Arm: Fix performance issue with thumb-2 tailcalls
We currently use a padding NOP after a Thumb to Arm interworking veneer (BX pc).
The NOP is never executed but may result in a performance penalty on some cores.
For this reason this patch changes the NOPs after Thumb to Arm veneers into B .-2
and adds a note to this in the source code for future reference.

* elf32-arm.c (elf32_thumb2_plt_entry, elf32_arm_plt_thumb_stub,

previous instruction.

commit d7a11d1383a2d0cdffc8c08e46b0cf5a66b3ce28

[gdb/testsuite] Clean up stale exec in gdb_compile_pascal
When running a pascal test with the stabs target board:
...
$ test=gdb.pascal/case-insensitive-symbols.exp
$ cd build/gdb/testsuite
$ make check RUNTESTFLAGS="$test --target_board=stabs"
...
we get:
...
nr of untested testcases 1
nr of unsupported tests 1
...
due to:
...
Error: Illegal parameter: -gstabs+^M
Error: /usr/bin/ppcx64 returned an error exitcode^M
...
OTOH, when running the same pascal test without the stabs target board:
...
$ make check RUNTESTFLAGS="$test"
...
we get:
...
nr of expected passes 20
...
But when subsequently again running with the stabs target board:
...
$ make check RUNTESTFLAGS="$test --target_board=stabs"
...
we now get:
...
nr of expected passes 20
...
The problem is that gdb_compile_pascal determines success based on existence
of the exec after compilation:
...
if ![file exists $destfile] {
unsupported "Pascal compilation failed: $result"
return "Pascal compilation failed."
}
...
without removing the exec before compilation, which allows a stale exec to
make it seem as if compilation has succeeded.
Fix this by removing the stale exec before compilation.
gdb/testsuite/ChangeLog:
2019-08-20 Tom de Vries <tdevries@suse.de>
* lib/pascal.exp (gdb_compile_pascal): Remove $destfile before
compilation.

Improve remote attach round-trips without btrace
For remotes which do not support btrace at all, we can save several
round trips for each thread. This is especially significant when your
remote is a kernel with 100s or 1000s of threads and latency is
intercontinental.
Previously, with target, remote, and infrun debugging enabled, one
might see:
Sending packet: $Hg18aee#43...Ack
Packet received: OK
Sending packet: $Hg186f7#eb...Ack
Packet received: OK
remote:target_xfer_partial (24, , 0x805454000, 0x0, 0x0, 4096) = -1, 0
repeated for all non-exited threads.
Afterwards, if the remote does not specify 'qXfer:btrace-conf:read+'
in qSupported stub features, these unnecessary thread switches are
avoided.
gdb/ChangeLog:
* remote.c (remote_target::remote_btrace_maybe_reopen): Avoid
unnecessary thread walk if remote doesn't support the packet.

Fix Fortran regression with variables in nested functions
Sergio pointed out that commit commit aa3b6533 ("Allow nested function
displays") regressed a few gdb.fortran tests. I was able to reproduce
these failures with gcc head.
The bug is that some spots calling contained_in will in fact do the
wrong thing if nested functions are considered as contained. In the
particular case of the Fortran regression, it was the call in
block_innermost_frame, being called from get_hosting_frame -- in this
case, the caller is specifically trying to avoid the nested case.
This patch fixes the problem by adding an "allow_nested" parameter to
contained_in, essentially reverting the change for most callers.

Add Rust support to source highlighting
Currently, no release of GNU Source Highlight supports Rust. However,
I've checked in a patch to do so there, and I plan to make a new
release sometime this summer.
This patch prepares gdb for that by adding support for Rust to the
source highlighting code.
Because Source Highlight will throw an exception if the language is
unrecognized, this also changes gdb to ignore exceptions here. This
will cause gdb to fall back to un-highlighted source text.
This updates gdb's configure script to reject the combination of
Source Highlight and -static-libstdc++. This is done because it's not
possible to use -static-libstdc++ and then catch exceptions from a
shared library.
Tested with the current and development versions of Source Highlight.

* configure: Rebuild.
* configure.ac: Disallow the combination of -static-libstdc++ and
source highlight.

Add --with-static-standard-libraries to the top level
gdb should normally not be linked with -static-libstdc++. Currently
this has not caused problems, but it's incompatible with catching an
exception thrown from a shared library -- and a subsequent patch
changes gdb to do just this.
This patch adds a new --with-static-standard-libraries flag to the
top-level configure. It defaults to "auto", which means enabled if
gcc is being built, and disabled otherwise.

Fix N^2 behavior in _bfd_dwarf2_find_symbol_bias
A customer reported a case where addr2line was very slow. We tracked
this down to some N^2 behavior in _bfd_dwarf2_find_symbol_bias in the

This patch fixes the bug, and reduces the runtime for a particular

Float16: Fix test failures for non ELF targets
The tests were failing due to md_atof trying to do word-wise endian
switching on the float16 (for little-endian targets sometimes
multi word values have their word order changed).
However since a float16 is only 1 word wide, it would end up writing
incorrect data, as you cannot switch the word order of just one word.

The test expects the read-only sections to have the same contents as in the

Remove the TUI execution info window
The TUI execution info window is unusual in that it is always linked
to a source or disassembly window. Even updates of its content are
handled by the source window, so it really has no life of its own.
This patch removes this window entirely and puts its functionality
directly into the source window. This simplifies the code somewhat.
This is a user-visible change, because now the box around the source
(or disassembly) window encloses the execution info as well. I
consider this an improvement as well, though.
Note that this patch caused ncurses to start emitting the "CSI Z"
sequence, so I've added this to the test suite terminal
implementation.

Given R_PPC_ADDR32 or R_PPC_UADDR32 relocs, this patch generates
R_PPC_ADDR32 or R_PPC_UADDR32 dynamic relocs from either type
depending on whether r_offset is 4-byte aligned, and similarly for
R_PPC_ADDR16/R_PPC_UADDR16.
* elf32-ppc.c (ppc_elf_relocate_section): Optimize unaligned relocs.

Fix paste-o in examine-backward.exp.
This patch fixes a paste-o that was introduced in commit
c8ad9b9a31aa3e6039567fc1f152dd454c946d5f. Previously the regexp for
the "examine 3 bytes backward from ${address_zero}" test correctly
matched 3 "${byte}" patterns, but in that commit the 6-byte regexp
from the previous test was mistakenly repeated here instead.

[gdb] Make maint info sections print relocated addresses
When running gdb.base/compare-sections.exp with -fPIE/-pie, we get:
...
print /u *(unsigned char *) 0x00000238^M
Cannot access memory at address 0x238^M
(gdb) FAIL: gdb.base/compare-sections.exp: read-only: get value of read-only section
...
The problem is that that "maint info sections" prints an unrelocated address:
...
[0] 0x00000238->0x00000254 at 0x00000238: .interp ALLOC LOAD READONLY \
DATA HAS_CONTENTS
...
while the test expects a relocated address.
Given that the documentation states that the command displays "the section
information displayed by info files", and that info files shows relocated
addresses:
...
0x0000555555554238 - 0x0000555555554254 is .interp
...
fix this by showing relocated addresses for maint info sections as
well.

TUI resize unification
The TUI currently has two different ways to resize a window: the
resize method, and the methods make_invisible_and_set_new_height and
make_visible_with_new_height.
There's no deep reason to have two different ways to resize a window,
so this patch unifies them, leaving just the "resize" method.
This also changes the locator to be handled more like an ordinary
window and less like an adjunct of the associated source window.

gnat encodes character enumeration literals using a few different

RISC-V: Fix lui relaxation issue with code at address 0.
This fixes a problem originally reported at
https://github.com/riscv/riscv-binutils-gdb/issues/173
If you have code linked at address zero, you can have a lui instruction
loading a value 0x800 which gets relaxed to a c.lui which is valid (c.lui 0x1
followed by addi -0x800). Relaxation can reduce the value below 0x800 at which
point the c.lui 0x0 is no longer valid. We can fix this by converting the
c.lui to a c.li which can load 0.

TUI window resize should not need invisibility
When resizing a window, the TUI currently first makes it invisible,
then changes the size, and then restores its visibility.
I think this is done because curses doesn't truly support resizing a
window -- there is a "wresize" extension, but the man page says it
isn't available in all versions of curses.
First, this is probably not a major problem any more. I imagine most
of those old systems are gone now.
Second, I think it's a better API to have this detail hidden inside of
the resize method.
This patch changes the code to follow this idea, and changes the
ordinary resize method to use wresize when it is available. The
special case for the command window is also moved to methods on the
command window.

Remove tui_alloc_source_buffer
There is no longer any need for tui_alloc_source_buffer. The two
callers of this function immediately change the contents of the
window, undoing the work done by this function.
This required adding a move constructor to tui_source_element -- a
mildly surprising find, but without this, resizing the vector will
cause crashes. This issue was masked earlier because
tui_alloc_source_buffer handled this.
Note that a patch for this bug was submitted here:

Skip batch-preserve-term-settings.exp tests that cannot work on Windows.
This group of tests assume that the gdb "shell" command launches a
POSIX-compliant shell supporting the PPID environment variable, which
is used to get gdb's pid for killing it from a remote_exec shell. But
on Windows host "shell" launches cmd.exe, which doesn't have an
equivalent query.

Replace write_inferior_memory with target_write_memory
target_write_memory is just a simple wrapper for
write_inferior_memory. Because target_write_memory is needed for
gdbsupport, and because gdb uses the name "target_write_memory"
everywhere, this patch renames write_inferior_memory and removes the
wrapper. I think this brings gdb and gdbserver slightly more in sync.

Fix CU overrun in scan_unit_for_symbols
A customer program had a DWARF CU that consisted of just a CU DIE,
without any children. In this situation, scan_unit_for_symbols will
try to read past the end of the current CU, and will take use the
first bytes of the next CU as an abbrev, printing an error message.
This patch fixes the bug by changing scan_unit_for_symbols to stop at
the end of the CU rather than the end of the .debug_info section.

AArch64: Allow additional sizes in prologue
When saving registers to the stack at the start of a function, not all state
needs to be saved. For example, only the first 64bits of float registers need
saving. However, a program may choose to store extra state if it wishes,
there is nothing preventing it doing so.
The aarch64_analyze_prologue will error if it detects extra state being
stored. Relex this restriction.
Tested via aarch64-prologue test.

register sizes.

Don't track the contents of the execution info window
The curses library keeps track of the contents of each window, and can

One call to tui_erase_exec_info_content can be removed. This call is

the only call to tui_erase_exec_info_content, so

removed.

to tui_make_all_invisible and removes the call from show_data.

I was curious why updating readline caused so much to be to rebuilt,

[gdb/testsuite] Fix gdb.gdb/selftest.exp regexp

The failure is due to gdb printing 'Thread 1 "xgdb" received signal SIGINT',

Fix gdb's selftest.exp after readline import
After the sync there is one testsuite regression, the test
"signal SIGINT" in gdb.gdb/selftest.exp which now FAILs. Previously,
the readline 6.2 SIGINT handler would temporarily reinstall the
underlying application's SIGINT handler and immediately re-raise SIGINT
so that the orginal handler gets invoked. But now (since readline 6.3)
its SIGINT handler does not re-raise SIGINT or directly invoke the
original handler; it now sets a flag marking that SIGINT was raised, and
waits until readline explicitly has control to call the application's
SIGINT handler. Anyway, because SIGINT is no longer re-raised from
within readline's SIGINT handler, doing "signal SIGINT" with a stopped
inferior gdb process will no longer resume and then immediately stop the
process (since there is no 2nd SIGINT to immediately catch). Instead,
the inferior gdb process will now just print "Quit" and continue to run.
So with this commit, this particular test case is adjusted to reflect
this change in behavior (we now have to send a 2nd SIGINT manually to
stop it).

* gdb.gdb/selftest.exp (test_with_self): Update test to now

Add generic and ARM specific support for half-precision IEEE 754 floating point numbers to the assembler.
Half precision floating point numbers will be encoded using the IEEE 754
half precision floating point format - 16 bits in total, 1 for sign, 5
for exponent and 10 bits of mantissa.
This patch implements the float16 directive for both the IEEE 754 format
and the Arm alternative format for the Arm backend.
The syntax of the directive is:
.float16 <0-n decimal numbers>
e.g.
.float16 12.0
.float16 0.23, 433.1, 0.06
The Arm alternative format is almost identical to the IEEE 754 format,
except that it doesn't encode for NaNs or Infinity (instead an exponent
of 0x1F represents a normalized number in the range 65536 to 131008).
The alternative format is documented in the reference manual:
https://static.docs.arm.com/ddi0487/db/DDI0487D_b_armv8_arm.pdf?_ga=2.72318806.49764181.1561632697-999473562.1560847439
Which format is used is controlled by the .float16_format <format>
directive, where if <format> = ieee, then use the IEEE 754
half-precision format else if <format> = alternative, then use the
Arm alternative format
Or the format can be set on the command line via the -mfp16-format
option that has a similar syntax. -mfp16-format=<ieee|alternative>.
This also fixes the format and it cannot be changed by any directives.
Once the format has been set (either by the command line option or a directive) it cannot be changed,
and any attempts to change it (i.e. with the float16_format directive) will result in a warning and the
line being ignored.
For ELF targets the appropriate EABI attribute will be written out at the end of assembling
if the format has been explicitly specified. If no format has been explicitly specified then no
EABI attributes will be written.
If the format is not explicitly specified then any float16 directives are encoding using the IEEE 754-2008
format by default until the format is fixed or changed with the float16_format directive.

Fix access to uninitialized variable in fill_in_stop_func
This patch changes find_pc_partial_function so that *block is set to
nullptr when it fails, so that fill_in_stop_func won't access an
uninitialized variable.

s390: Implement 'type_align' gdbarch method
The align.exp test case yields many FAILs on s390x, since GDB's _Alignoff
doesn't always agree with the compiler's. On s390x, the maximum alignment
is 8, but GDB returns an alignment of 16 for 16-byte data types such as
"long double".
This is fixed by implementing the type_align gdbarch method. The new
method returns an alignment of 8 for all integer, floating-point, and
vector types larger than 8 bytes. With this change, all align.exp tests
pass.

* s390-tdep.c (s390_type_align): New function.
(s390_gdbarch_init): Set it as type_align gdbarch method.

Add support for a MIPS specific .MIPS.xhash section.
This patch is a reimplementation of [1] which was submitted in 2015 by
Neil Schellenberger. Copyright issue was sorted out [2] last year.
It proposed a new section (.gnu.xhash) and related dynamic tag
(DT_GNU_XHASH). The new section would be virtually identical to the
existing .gnu.hash except for the translation table (xlat) which would
contain correct MIPS .dynsym indexes corresponding to the hashvals in
chains. This is because MIPS ABI imposes a different ordering on the
dynsyms than the one expected by the .gnu.hash section. Another addition
would be a leading word (ngnusyms) which would contain the number of
entries in the translation table.
In this patch, the new section name and dynamic tag are changed to
reflect the fact that the section should be treated as MIPS-specific
(.MIPS.xhash and DT_MIPS_XHASH).
This patch addresses the alignment issue as reported in [3], which is
caused by the leading word added to the .MIPS.xhash section. Leading word
is removed in this patch, and the number of entries in the translation
table is now calculated using DT_MIPS_SYMTABNO dynamic tag (this is
addressed by the corresponding glibc patch).
Suggestions on coding style in [4] were taken into account. Existing
GNU hash testcase was covered, and another one was added in the MIPS
part of the testsuite.
The other major change is reserving MIPS ABI version 5 for .MIPS.xhash,
marking the need of support for .MIPS.xhash in the dynamic linker (again,
addressed in the corresponding glibc patch). This is something which I
am not sure of, especially after reading [5]. I am confused on whether
this ABI version is reserved for IFUNC, or it can be used for this
purpose.
Already mentioned glibc patch is submitted at:

[gdb] Fix gdb.dwarf2/varval.exp with -fPIE/-pie
With target board unix/-fPIE/-pie, we get:
...
FAIL: gdb.dwarf2/varval.exp: print varval2
...
This is due comparing a get_frame_pc result (which includes the for PIE
non-zero relocation offset) with pc_high and pc_low obtained using
get_scope_pc_bounds (which do not include the relocation offset).
Fix this by adjusting pc_high and pc_low with the relocation offset.

[gdb/testsuite] Fix gdb.tui/basic.exp with check-read1
With gdb.tui/basic.exp and check-read1, we run into (using -v for
verbose log):
...
^[[0+++ _csi_0 <<<>>>
ERROR: (DejaGnu) proc "_csi_0" does not exist.
...
In contrast, without check-read1, we have:
...
^[[0;10m<SNIP>+++ _csi_m <<<0;10>>>
...
The problem is that this regexp in _accept:
...
-re "^\x1b\\\[(\[0-9;\]*)(\[0-9a-zA-Z@\])" {
...
while matching the longer sequence '^[' '[' '0' ';' '1' '0' 'm', also matches
the shorter sequence '^[' '[' '0'.
The regexp attempts to match a CSI (Control Sequence Introducer) sequence, and
the final byte of such a sequence cannot be a digit.
Fix the regexp accordingly:
...
- -re "^\x1b\\\[(\[0-9;\]*)(\[0-9a-zA-Z@\])" {
+ -re "^\x1b\\\[(\[0-9;\]*)(\[a-zA-Z@\])" {

AArch64 pauth: Indicate unmasked addresses in backtrace
Armv8.3-a Pointer Authentication causes the function return address to be
obfuscated on entry to some functions. GDB must unmask the link register in
order to produce a backtrace.
The following patch adds markers of [PAC] to the bracktrace, to indicate
which addresses needed unmasking. This includes the backtrace when using MI.
For example, consider the following backtrace:
(gdb) bt
0 0x0000000000400490 in puts@plt ()
1 0x00000000004005dc in foo ("hello") at cbreak-lib.c:6
2 0x0000000000400604 [PAC] in bar () at cbreak-lib.c:12
3 0x0000000000400620 [PAC] in main2 () at cbreak.c:17
4 0x00000000004005b4 in main () at cbreak-3.c:10
The functions in cbreak-lib use pointer auth, which masks the return address
to the previous function, causing the addresses of bar (in the library) and main2
(in the main binary) to require unmasking in order to unwind the backtrace.
An extra bool is added alongside the prev_pc in the frame structure. At the
point at which the link register is unmasked, the AArch64 port calls into frame
to sets the bool. This is the most efficient way of doing it.
The marker is also added to the python frame printer, which is always printed if
set. The marker is not explicitly exposed to the python code.
I expect this will potentially cause issues with some tests in the testsuite
when Armv8.3 pointer authentication is used. This should be fixed up in the
the future once real hardware is available for full testsuite testing.

ld: use a specific linker script in BPF targets
This patch makes the elf64bpf emulation to use it's own linker script,
based on elf.sc. At the moment, the only change is that the BPF
executable doesn't define an entry symbol (BPF programs feature
several entry points scattered in several sections.)
This is a step towards the goal of generating proper ELF executables
that would be loaded by the kernel's libbpf. We are not there yet:
BPF "programs" should still be linked with -r.
This change removes a warning while linking executables, decreases the
number of unsupported tests in the target from 47 to 29, and increases
the number of expected passes from 104 to 145.
Regtested in x86_64 for all targets.
No regressions.

Add a selftest that checks documentation invariants.
Several approaches were discussed (mail or irc) to verify the invariants of
the GDB help documentation : checking with apropos ., modifying add_cmd
to do the check and output a warning, implement maintenance check-doc.
A selftest was finally chosen as:
* this can be run on demand, including by users if they want
to check user defined commands.
* it does not interact with the normal behaviour of apropos, define,
python, ...
(such as output warnings when a user defines a command help that
does not respect the doc).
* when the selftest runs, it checks the user defined and python
defined commands currently defined.

Make first and last lines of 'command help documentation' consistent.
With this patch, the help docs now respect 2 invariants:
* The first line of a command help is terminated by a '.' character.
* The last character of a command help is not a newline character.
Note that the changes for the last invariant were done by Tom, as part of :
[PATCH] Remove trailing newlines from help text
https://sourceware.org/ml/gdb-patches/2019-06/msg00050.html
but some occurrences have been re-introduced since then.
Some help docs had to be rephrased/restructured to respect the above
invariants.
Before this patch, print_doc_line was printing the first line
of a command help documentation, but stopping at the first '.'
or ',' character.
This was giving inconsistent results :
* The first line of command helps was sometimes '.' terminated,
sometimes not.
* The first line of command helps was not always designed to be
readable/understandable/unambiguous when stopping at the first
'.' or ',' character.
This e.g. created the following inconsistencies/problems:
< catch exception -- Catch Ada exceptions
< catch handlers -- Catch Ada exceptions
< catch syscall -- Catch system calls by their names
< down-silently -- Same as the `down' command
while the new help is:
> catch exception -- Catch Ada exceptions, when raised.
> catch handlers -- Catch Ada exceptions, when handled.
> catch syscall -- Catch system calls by their names, groups and/or numbers.
> down-silently -- Same as the `down' command, but does not print anything.
Also, the command help doc should not be terminated by a newline
character, but this was not respected by all commands.
The cli-option -OPT framework re-introduced some occurences.
So, the -OPT build help framework was changed to not output newlines at the
end of %OPTIONS% replacement.
This patch changes the help documentations to ensure the 2 invariants
given above.
It implied to slightly rephrase or restructure some help docs.
Based on the above invariants, print_doc_line (called by
'apropos' and 'help' commands to print the first line of a command
help) now outputs the full first line of a command help.
This all results in a lot of small changes in the produced help docs.
There are less code changes than changes in the help docs, as a lot
of docs are produced by some code (e.g. the remote packet usage settings).

[PR build/24886] disable glibc mcheck support
This patch drops gdb's configury support for glibc's mcheck function.
It has been observed to cause false abort()s, because it is
thread-unsafe yet interposes every malloc/free operation. So if any
library transitively used by gdb also uses threads, then these
functions can easily corrupt their own checking data. These days, gcc
ASAN and valgrind provide high quality checking, and mcheck is
apparently itself being slowly deprecated.
So, let's stop linking to it. Attached patch drops the
autoconf/Makefile machinery for both gdb and gdbserver. No
testsuite-visible impact. IMHO not worth mentioning in NEWS.

Add more styling to "disassemble"
This adds more styling to the disassemble command. In particular,
addresses and function names in the disassembly are now styled.
This required fixing a small latent bug in set_output_style. This
function always passed NULL to emit_style_escape; but when writing to
a file other than gdb_stdout, it should emit the style escape
directly. (FWIW this is another argument for better integrating the
pager with ui_file and getting rid of this entire layer.)

Clean up source file error reporting
print_source_lines_base reopens the source file every time that a
source line is to be printed. However, there's no need to do this so
frequently -- it's enough to do it when switching source files, and
otherwise rely on the cache.
The code seems to try to avoid these multiple opens; at a guess I'd
say something just got confused along the way.
This patch fixes the problem by reorganizing the code both to make it
more clear, and to ensure that reopens only occur when the "last
source visited" changes.

Add file offsets to the source cache
Currently, gdb stores the number of lines and an array of file offsets
for the start of each line in struct symtab. This patch moves this
information to the source cache. This has two benefits.
First, it allows gdb to read a source file less frequently.
Currently, a source file may be read multiple times: once when
computing the file offsets, once when highlighting, and then pieces
may be read again while printing source lines. With this change, the
file is read once for its source text and file offsets; and then
perhaps read again if it is evicted from the cache.
Second, if multiple symtabs cover the same source file, then this will
share the file offsets between them. I'm not sure whether this
happens in practice.

Fix latent bug in source cache
The source cache was not returning the final \n of the requested range
of lines. This caused regressions with later patches in this series,
so this patch pre-emptively fixes the bug.

make it simpler to test, I changed extract_lines to be a static

LTO object insertion point
This is a mostly cosmetic fix for cases like PR24873 where LTO
recompiled objects were supposed to be inserted inside a group. The
specific case handled by this patch is when the first file inside a
group is an archive, the first file claimed by the plugin. Prior to
this patch we would have inserted the recompiled objects before the
group, which doesn't matter really since the entire group will be
reloaded, but it looks a little wrong in map files.

PR24873, gcc -flto objects result in --start-group .. --end-group failure to include --as-needed libraries
Reloading of archives (and checking --as-needed DSOs again) is
disabled until we hit the plugin insert point. It's necessary to do
that because in a case like lib1.a lto.o lib2.a where lib1.a and
lib2.a contain duplicate symbols, we want the lto.o recompiled object
to pull in objects from lib2.a as necessary, but not from lib1.a.
Unfortunately this heuristic fails when the insert point is inside a
group, because ld actually loads the symbols from the recompiled
object before running over the contours of the script, thus missing
the fact that new undefs appeared in the group.

Increase timeout in gdb.mi/list-thread-groups-available.exp
Running
make check-read1 TESTS="gdb.mi/list-thread-groups-available.exp"
on my machine results in timeout failures. Running it while having
`tail -F testsuite/gdb.log` on the side shows that the test is never
really blocked, it is just slow at consuming the large output generated
by `-list-thread-groups --available` (which lists all the processes on
the system).
If I increase the timeout to a large value, the test passes in ~30
seconds (compared to under 1 second normally).
Increase the timeout for the particular mi_gdb_test that is long to
execute under read1. The new timeout value is a bit arbitrary. The
default timeout is 10 seconds, so I set the new timeout to be
"old-timeout * 10", so 100 seconds in the typical case.

Use _() in calls to build_help
Currently some code in gdb uses build_help with N_(), like:
static const std::string compile_print_help
= gdb::option::build_help (N_("\
I believe this is incorrect. The N_ macro is used to mark text that
should end up in the message catalog, but which will be translated by
a later call to gettext.
However, in this case, there is no later call to gettext, so (if gdb
had translations), this text would remain untranslated.
Instead, I think using the ordinary _() macro is correct here.
Translators will have to know to preserve "%OPTIONS%" in the text --
but that seems both unavoidable and fine.

While reading that code, I noticed that some variables essentially meant
whether to consider some other variable or not. I think using
gdb::optional (which was not available when this code was written) is
clearer, as it embeds the used/not used predicate directly in the type

xtensa: bfd: add special case to loop alignment check
check_loop_aligned is used during link time relaxation to only allow
transformations that don't violate loop body alignment requirements.
Assembler can relax loops that have too long body by adding instructions
between the loop instruction and the loop body. check_loop_aligned must
check alignment of the first instruction of the actual loop body.
Detect loop / rsr.lend / wsr.lbeg sequence used in assembly time
relaxation and adjust alignment check when it's detected.

Include s12z-opc.h using ../opcodes.
This file exists in binutils-gdb/opcodes, and nothing in Makefile.in adds this

binutils-gdb/ to the include path (!). However, this is broken when compiling
with system readline.
Other files already use this way to include files in opcodes:

Require GNU make 3.82
Gdbserver has failed to build with GNU make 3.81 since commit 08f10e02be.
Update the NEWS file to state that versions earlier than 3.82 are not
supported.
3.82 was released in 2010, 3.81 was released 2006. A quick investigation
of the default GNU make version provided across various distros found the
earliest provided version to be 3.82:
*RHEL 7, Centos 6 - make 3.82
*Fedora 27 - make 4.2.1
*OpenSuse 42.2, SLES11 - make 4.2.1
*Ubuntu 16.04/18.04 - make 4.1
*Debian Jessie - make 4.0
Note that Glibc requires at least 4.0, whereas GCC still allows 3.81.

Allow nested function displays
In Ada, it's possible to have nested functions. However,
block.c:contained_in does not recognize this. Normally, this is no
problem, but if gdb is stopped inside a nested function, then you can
end up in the unexpected situation that "print" of an expression will
work, whereas "display" of the same expression will not -- because
contained_in returns 0.
This patch simply removes the BLOCK_FUNCTION check from contained_in.
The rationale here is that in languages without nested functions, this
will not cause any issues.

Allow display of negative offsets in print_address_symbolic()
When examining addresses associated with blocks with non-contiguous
address ranges, it's not uncommon to see large positive offsets which,
for some address width, actually represent a smaller negative offset.
Here's an example taken from the test case (using the
dw2-ranges-func-lo-cold executable):
(gdb) x/5i foo_cold
0x40110d <foo+4294967277>: push %rbp
0x40110e <foo+4294967278>: mov %rsp,%rbp
0x401111 <foo+4294967281>: callq 0x401106 <baz>
0x401116 <foo+4294967286>: nop
0x401117 <foo+4294967287>: pop %rbp
This commit, in conjuction with an earlier patch from this series, causes
cases like the above to be displayed like this (below) instead:
(gdb) x/5i foo_cold
0x40110d <foo_cold>: push %rbp
0x40110e <foo-18>: mov %rsp,%rbp
0x401111 <foo-15>: callq 0x401106 <baz>
0x401116 <foo-10>: nop
0x401117 <foo-9>: pop %rbp
Note that the address of foo_cold is now (due to another patch) being
displayed as <foo_cold> instead of <foo+BigOffset>. The subsequent
lines are shown as negative offsets from foo.
Disassembly using the "disassemble" command is somewhat affected by
these changes:
Before:
(gdb) disassemble foo_cold
Dump of assembler code for function foo:
Address range 0x401120 to 0x40113b:
0x0000000000401120 <+0>: push %rbp
0x0000000000401121 <+1>: mov %rsp,%rbp

There are several things here interacting with environment variable
LD_PRELOAD:
- the expect "binary" build/gdb/testsuite/expect-read1 with does
export LD_PRELOAD=build/gdb/testsuite/read1.so before calling native expect
- read1.so which does unsetenv ("LD_PRELOAD") upon first call to read
- the test-case, which wants to set or append libSegFault.so to LD_PRELOAD
The error occurs when accessing $env(LD_PRELOAD), in a branch where
"info exists env(LD_PRELOAD)" returns true. AFAIU, this is
https://core.tcl-lang.org/tcl/tktview?name=67fd4f973a "incorrect results of
'info exists' when unset env var in one interp and check for existence from
another interp".
Work around the tcl bug by not unsetting the variable, but setting it to ""
instead:
...
- unsetenv ("LD_PRELOAD");
+ setenv ("LD_PRELOAD", "", 1);
...
Verified that reverting commit de28a3b72e "[gdb/testsuite, 2/2] Fix
gdb.linespec/explicit.exp with check-read1" reintroduced the check-read1
failure in gdb.linespec/explicit.exp.

[gdb/testsuite] Fail in gdb_compile if nopie results in PIE executable
When running gdb.base/dump.exp with --target_board=unix/-fPIE/-pie, we get:
...
Running gdb/testsuite/gdb.base/dump.exp ...
FAIL: gdb.base/dump.exp: dump array as value, intel hex
...
The FAIL happens because although the test specifies nopie, the exec is
in fact compiled as PIE. The "-fPIE -pie" options specified using the
target_board are interpreted by dejagnu as multilib_flags, and end up
overriding the nopie flags.
Fix this by checking in gdb_compile if the resulting exec is PIE despite of
a nopie setting, and if so return an error:
...
Running gdb/testsuite/gdb.base/dump.exp ...
gdb compile failed, nopie failed to prevent PIE executable

Two fixes for test suite's terminal
Exactly which escape sequences are emitted by gdb in TUI mode are
determined largely by the curses implementation. Testing my latest
(as yet unsubmitted) series to refactor the TUI showed a couple of
failures that I tracked to the test suite's terminal implementation.
In particular, the CSI "@" sequence was not implemented; and the CSI
"X" sequence was implemented incorrectly.
This patch fixes both of these problems. Tested on x86-64 Fedora 28.

Implement 'set print frame-info|frame-arguments presence'.
New settings allow to better control what frame information is printed.
'set print frame-info' allows to override the default frame information
printed when a GDB command prints a frame.
The backtrace command has a new option -frame-info to override
this global setting.
It is now possible to have very short frame information by using the
new 'set print frame-arguments presence' and
'set print frame-info short-location'.
Combined with 'set print address off', a backtrace will only show
the essential information to see the function call chain, e.g.:
(gdb) set print address off
(gdb) set print frame-arguments presence
(gdb) set print frame-info short-location
(gdb) bt
#0 break_me ()
#1 call_me (...)
#2 main ()
(gdb)
This is handy in particular for big backtraces with functions having
many arguments.
Python frame filter printing logic has been updated to respect the new
setting in non MI mode.
Also, the default frame information printed was inconsistent when
backtrace was printing the frame information itself, or when the python
frame filtering code was printing the frame information.
This patch changes the default of python frame filtering to have a
consistent behaviour regarding printed frame-information, whatever
the presence/activity/matches of python filters.

[gdb/testsuite, 2/2] Fix gdb.linespec/explicit.exp with check-read1
When running gdb.linespec/explicit.exp with check-read1, we get:
...
(gdb) PASS: gdb.linespec/explicit.exp: set max-completions unlimited

(gdb) PASS: gdb.linespec/explicit.exp: complete with no arguments
break
-function

top
(gdb) FAIL: gdb.linespec/explicit.exp: complete with no arguments (clearing input line)

The problem is that the send_gdb "\t\t" triggers completion twice:
...
set tst "complete with no arguments"
send_gdb "break \t"
gdb_test_multiple "" $tst {
"break \\\x07" {
send_gdb "\t\t"
gdb_test_multiple "" $tst {
...
}
clear_input_line $tst
...
but the following gdb_test_multiple only parses it once, so the second
completion is left for clear_input_line, which fails.
Fix this by triggering completion only once.

[gdb/testsuite, 1/2] Fix gdb.linespec/explicit.exp with check-read1
When running gdb.linespec/explicit.exp with check-read1, we get:

break -source exp^Glicit^G^M

(gdb) FAIL: gdb.linespec/explicit.exp: complete non-unique file name

The problem is that we have a gdb_test_multiple where we match two regexps:
...
set tst "complete non-unique file name"
send_gdb "break -source exp\t"
gdb_test_multiple "" $tst {
-re "break -source exp\\\x07licit" {
...
}
-re "break -source exp\\\x07l" {
# This pattern may occur when glibc debuginfo is installed.
...
}
}
...
but since second is a substring of the first, we'll usually match the first,
but with check-read1 we'll match the second.
Fix this by using a single regexp and merging the related code.

[gdb/testsuite] Fix python.exp with check-read1
when running python/python.exp with check-read1, we get:
...
(gdb) PASS: gdb.python/python.exp: prompt substitution readline - end

File "<string>", line 3, in error_prompt^M
RuntimeError: Python exception called^M
(gdb) FAIL: gdb.python/python.exp: set the hook to default
...
The problem is that gdb_test_multiple here:
...
gdb_test_multiple "python gdb.prompt_hook = error_prompt" "set the hook" {
-re "Python Exception (exceptions.RuntimeError|<(type 'exceptions.|class ')RuntimeError'>) Python excepti
on called.*" {
pass "set hook"
}
}
...
specifies a regexp that ends with ".*" but doesn't specify the expected
$gdb_prompt.
Consequently, due to check-read1, the ".*" is matched to "" and the remaining
$gdb_prompt is read by the the following gdb_py_test_silent_cmd, which has
its own $gdb_prompt read by the following gdb_py_test_silent_cmd, which has
its own $gdb_prompt causing a mismatch for the following gdb_test_multiple:
...
gdb_test_multiple "python gdb.prompt_hook = error_prompt" "set the hook" {
-re "Traceback.*File.*line.*RuntimeError.*Python exception called.*" {
pass "set hook"
}
}
...
which causes both FAILs.
The second gdb_test_multiple has the same problem as the first, but it happens
not to cause a FAIL because it's followed by a gdb_py_test_silent_cmd and a
clean_restart.
Fix the regexps in both gdb_test_multiple calls.

PASS: gdb.base/maint.exp: maint print registers: got prompt
...
The problem is that when matching:
...
(gdb) maint print registers^M
Name Nr Rel Offset Size Type ^M
rax 0 0 0 8 int64_t ^M
...
the regexp for $saw_headers ends in "\[\r\n\]+", which
allows it to match only the "\r". The remaining "\n" then start the next line
to be matched, which doesn't match for the $saw_registers regexp since it
starts with "^\[^\r\n\]+".
Fix this by ending the regexps with "\r\n".

[gdb/testsuite] Fix gdb.base/define.exp with check-read1
When running gdb.base/define.exp with check-read1, we get:

The problem is that the "$gdb_prompt $" regexp here:
...
gdb_test_multiple "set prompt $prior_prompt " "reset gdb_prompt" {

}
}

triggers for the echoing of the command "set prompt $prior_prompt " rather
than for the prompt after the command has executed.
Fix this by changing the regexp to "\r\n$gdb_prompt $".

[gdb/testsuite] Don't expect gdb_prompt in mi_skip_python_test
When running gdb.python/py-mi-events.exp with make check-read1, we get:
...
(gdb) ^M
python print ('test')^M
&"python print ('test')\n"^M
~"test\n"^M
^done^M
(gdb) FAIL: gdb.python/py-mi-events.exp: verify python support
^M
python print (sys.version_info[0])^M
&"python print (sys.version_info[0])\n"^M
~"2\n"^M
^done^M
(gdb) FAIL: gdb.python/py-mi-events.exp: check if python 3
^M
...
The FAILs happen as follows.
On one hand, skip_python_tests_prompt uses the prompt_regexp parameter for the
user_code argument of gdb_test_multiple:
...
proc skip_python_tests_prompt { prompt_regexp } {
global gdb_py_is_py3k
gdb_test_multiple "python print ('test')" "verify python support" {
-re "not supported.*$prompt_regexp" {
unsupported "Python support is disabled."
return 1
}
-re "$prompt_regexp" {}
}
gdb_test_multiple "python print (sys.version_info\[0\])" "check if python 3" {
-re "3.*$prompt_regexp" {
set gdb_py_is_py3k 1
}
-re ".*$prompt_regexp" {
set gdb_py_is_py3k 0
}
}
...
On the other hand, gdb_test_multiple itself uses $gdb_prompt:
...
-re "\r\n$gdb_prompt $" {
if ![string match "" $message] then {
fail "$message"
}
set result 1
}
...
So when mi_skip_python_test calls skip_python_tests_prompt with prompt_regexp
set to $mi_gdb_prompt:
...
proc mi_skip_python_tests {} {
global mi_gdb_prompt
return [skip_python_tests_prompt "$mi_gdb_prompt$"]
}
...
and expect reads "(gdb) " and tries to match it (due to the READ1=1 setting),
the user_code regexps using $prompt_regexp (set to $mi_gdb_prompt) don't match,
but the $gdb_prompt regexp in gdb_test_multiple does match.
Fix this by adding a prompt_regexp parameter to gdb_test_multiple, and using the
parameter in skip_python_tests_prompt.
Tested gdb.python/py-mi-events.exp with make check READ1=1 x86_64-linux.

Fix stepping bug associated with non-contiguous blocks
I recently noticed the following behavior while debugging
dw2-ranges-func-low-cold. This is one of the test programs associated
with the test gdb.dwarf2/dw2-ranges-func.exp.
(gdb) b 70
Breakpoint 1 at 0x401129: file dw2-ranges-func-lo-cold.c, line 70.
(gdb) run
Starting program: dw2-ranges-func-lo-cold
Breakpoint 1, foo ()
at dw2-ranges-func-lo-cold.c:70
70 if (e) foo_cold (); /* foo foo_cold call */
(gdb) set var e=1
(gdb) step
[Inferior 1 (process 12545) exited normally]
This is incorrect. When stepping, we expect a step to occur. We do not
expect the program to exit. Instead, we should see the following behavior:
...
(gdb) set var e=1
(gdb) step
foo ()
at dw2-ranges-func-lo-cold.c:54
54 baz (); /* foo_cold baz call */
(Note that I've shortened the paths in the above sessions to improve
readability.)
The bug is in fill_in_stop_func() in infrun.c. While working on
non-contiguous address range improvements in 2018, I replaced the
call to find_pc_partial_function() with a call to
find_function_entry_range_from_pc(). Although this seemed like the
right thing to do at the time, I now think that calling
find_pc_partial_function (along with some other tweaks) is the right
thing to do.
For blocks with a single contiguous range, these functions do pretty
much the same thing: when the function succeeds, the function name,
start address, and end address are all filled in. Additionally,
find_pc_partial_function contains an additional output parameter
which is set to the block containing that PC.
For blocks with non-contiguous ranges, find_pc_partial_function
sets the start and end addresses to the start and end addresses
of the range containing the pc. find_function_entry_range_from_pc
does what it says; it sets the start and end addresses to those
of the range containing the entry pc.
The reason that I had thought that using the entry pc range was
correct is due to the fact that fill_in_stop_func() contains some
code for advancing past the function start and entry point. To do
this, we'd need the range that contains the entry pc.
However, when stepping, we actually want the range that contains the
stop pc. If that range also contains the entry pc, we should then
attempt to advance stop_func_start past the start offset and entry
point. (I haven't thought very hard about the reason for advancing
the stop_func_start in this manner. Since it's been there for quite
a while, I'm assuming that it's still a good idea.)
Back when I wrote the test case, I had included a test for doing the
step shown in the example above. I had problems with it, however. At
the time, I thought it was due to differing compiler versions, so I
disabled that portion of the test. I have now reenabled those tests,
but have left in place the logic which may be used to disable it.
The changes to dw2-ranges-func.exp depend on my other recent changes
to the file which have not been pushed yet.
Finally, I'll note that the only caller of
find_function_entry_range_from_pc() is/was fill_in_stop_func(). Once
this commit goes in, it'll be dead code. I considered removing it,
but I think that it ought to be used (instead of
find_pc_partial_function) for determining the correct range to scan
for prologue analysis, so I'm going to leave it in place for now.
gdb/ChangeLog:
* infrun.c (fill_in_stop_func): Use find_pc_partial_function
instead of find_function_entry_range_from_pc.
testsuite/ChangeLog:
* gdb.dwarf2/dw2-ranges-func.exp (enable_foo_cold_stepping):

Improve test gdb.dwarf2/dw2-ranges-func.exp
The original dw2-ranges-func.exp test caused a function named foo to be
created with two non-contiguous address ranges. In the C source file,
a function named foo_low was incorporated into the function foo which
was also defined in that file. The DWARF assembler is used to do this
manipulation. The source file had been laid out so that foo_low would
likely be placed (by the compiler and linker) at a lower address than
foo().
The case where a range at a higher set of addresses (than foo) was not
being tested. In a recent discussion on gdb-patches, it became clear
that performing such tests are desirable because bugs were discovered
which only became evident when the other range was located at high(er)
addresses than the range containing the entry point for the function.
This other (non entry pc) address range is typically used for "cold"
code which executes less frequently. Thus, I renamed foo_low to
foo_cold and renamed the C source file from dw-ranges-func.c to
dw-ranges-func-lo.c. I then made a copy of this file, naming it
dw-ranges-func-hi.c. (That was my intent anyway. According to git,
I renamed dw-ranges-func.c to dw-ranges-func-hi.c and then modified it.
dw-ranges-func-lo.c shows up as an entirely new file.)
Within dw-ranges-func-hi.c, I changed the placement of foo_cold()
along with some of the other functions so that foo_cold() would be at
a higher address than foo() while also remaining non-contiguous. The
two files, dw-ranges-func-lo.c and dw-ranges-func-hi.c, are
essentially the same except for the placement of some of the functions
therein.
The tests in dw2-ranges-func.exp where then wrapped in a new proc named
do_test which was then called in a loop from the outermost level. The
loop causes each of the source files to have the same tests run upon
them.
I also added a few new tests which test functionality fixed by the other
commits to this patch series. Due to the reorganization of the file,
it's hard to identify these changes in the patch. So, here are the
tests which were added:
with_test_prefix "no-cold-names" {
# Due to the calling sequence, this backtrace would normally
# show function foo_cold for frame #1. However, we don't want
# this to be the case due to placing it in the same block
# (albeit at a different range) as foo. Thus it is correct to
# see foo for frames #1 and #2. It is incorrect to see
# foo_cold at frame #1.
gdb_test_sequence "bt" "backtrace from baz" {
"\[\r\n\]#0 .*? baz \\(\\) "
"\[\r\n\]#1 .*? foo \\(\\) "
"\[\r\n\]#2 .*? foo \\(\\) "
"\[\r\n\]#3 .*? main \\(\\) "
}
# Doing x/2i foo_cold should show foo_cold as the first symbolic
# address and an offset from foo for the second. We also check to
# make sure that the offset is not too large - we don't GDB to
# display really large offsets that would (try to) wrap around the
# address space.
set foo_cold_offset 0
set test "x/2i foo_cold"
gdb_test_multiple $test $test {
-re " (?:$hex) <foo_cold>.*?\n (?:$hex) <foo\[+-\](\[0-9\]+)>.*${gdb_prompt}" {
set foo_cold_offset $expect_out(1,string)
pass $test
}
}
gdb_assert {$foo_cold_offset <= 10000} "offset to foo_cold is not too large"
# Likewise, verify that second address shown by "info line" is at
# and offset from foo instead of foo_cold.
gdb_test "info line *foo_cold" "starts at address $hex <foo_cold> and ends at $hex <foo\[+-\].*?>.*"
}
When run against a GDB without the requisite bug fixes (from this patch
series), these 6 failures should be seen:

dwarf2-frame.c: Fix FDE processing bug involving non-contiguous ranges
In the course of revising the test case for
gdb.dwarf2/dw2-ranges-func.exp, I added a new .c file which would
cause the "cold" range to be at a higher address than the rest of the
function. In these tests, the range in question isn't really cold in
the sense that a compiler has determined that it'll be executed less
frequently. Instead, it's simply the range that does not include the
entry pc. These tests are intended to mimic the output of such a
compiler, so I'll continue to refer to this range as "cold" in the
following discussion.
The original test case had only tested a cold range placed
at lower addresses than the rest of the function. During testing of the
new code where the cold range was placed at higher addresses, I found
that I could produce the following backtrace:
(gdb) bt
#0 0x0000000000401138 in baz ()
at dw2-ranges-func-hi-cold.c:72
#1 0x0000000000401131 in foo_cold ()
at dw2-ranges-func-hi-cold.c:64
#2 0x000000000040111e in foo ()
at dw2-ranges-func-hi-cold.c:50
#3 0x0000000000401144 in main ()
at dw2-ranges-func-hi-cold.c:78
This is correct, except that we'd like to see foo() listed instead
of foo_cold(). (I handle that problem in another patch.)
Now look at what happens for a similar backtrace where the cold range
is at a lower address than the foo's entry pc:
(gdb) bt
#0 0x000000000040110a in baz ()
at dw2-ranges-func-lo-cold.c:48
#1 0x0000000000401116 in foo ()
at dw2-ranges-func-lo-cold.c:54
#2 0x00007fffffffd4c0 in ?? ()
#3 0x0000000000401138 in foo ()
at dw2-ranges-func-lo-cold.c:70
Note that the backtrace doesn't go all the way back to main(). Moreover,
frame #2 is messed up.
I had seen this behavior when I had worked on the non-contiguous
address problem last year. At the time I convinced myself that the
mangled backtrace was "okay" since we're doing strange things with
the DWARF assembler. We're taking a function called foo_cold (though
it was originally called foo_low - my recent changes to the test case
changed the name) and via the magic of the DWARF assembler, we're
combining it into a separate (non-contiguous) range for foo. Thus,
it was a surprise to me when I got a good and complete backtrace when
the cold symbol is placed at an address that's greater than entry pc.
The function dwarf2_frame_cache (in dwarf2-frame.c) is making this
call:
if (get_frame_func_if_available (this_frame, &entry_pc)) ...
If that call succeeds (returns a true value), the FDE is then
processed up to the entry pc. It doesn't make sense to do this,
however, when the FDE in question does not contain the entry pc. This
can happen when the function in question is comprised of more than one
(non-contiguous) address range.
My fix is to add some comparisons to the test above to ensure that
ENTRY_PC is within the address range covered by the FDE.
gdb/ChangeLog:
* dwarf2-frame.c (dwarf2_frame_cache): Don't decode FDE instructions
for entry pc when entry pc is out of range for that FDE.

Restrict use of minsym names when printing addresses in disassembled code
build_address_symbolic contains some code which causes it to
prefer the minsym over the the function symbol in certain cases.
The cases where this occurs are the same as the "certain pathological
cases" that used to exist in find_frame_funname().
This commit largely disables that code; it will only prefer the
minsym when the address of minsym is identical to that of the address
under consideration AND the function address for the symbtab sym is
not the same as the address under consideration.
So, without this change, when using the dw2-ranges-func-lo-cold
executable from the gdb.dwarf2/dw2-ranges-func.exp test, GDB exhibits
the following behavior:
(gdb) x/5i foo_cold
0x40110d <foo+4294967277>: push %rbp
0x40110e <foo+4294967278>: mov %rsp,%rbp
0x401111 <foo+4294967281>: callq 0x401106 <baz>
0x401116 <foo+4294967286>: nop
0x401117 <foo+4294967287>: pop %rbp
On the other hand, still without this change, using the
dw2-ranges-func-hi-cold executable from the same test, GDB
does this instead:
(gdb) x/5i foo_cold
0x401128 <foo_cold>: push %rbp
0x401129 <foo_cold+1>: mov %rsp,%rbp
0x40112c <foo_cold+4>: callq 0x401134 <baz>
0x401131 <foo_cold+9>: nop
0x401132 <foo_cold+10>: pop %rbp
This is inconsistent behavior. When foo_cold is at a lower
address than the function's entry point, the symtab symbol (foo)
is displayed along with a large positive offset which would wrap
around the address space if the address space were only 32 bits wide.
(A later patch fixes this problem by displaying negative offsets.)
This commit makes the behavior uniform for both the "lo-cold" and
"hi-cold" cases:
lo-cold:
(gdb) x/5i foo_cold
0x40110d <foo_cold>: push %rbp
0x40110e <foo-18>: mov %rsp,%rbp
0x401111 <foo-15>: callq 0x401106 <baz>
0x401116 <foo-10>: nop
0x401117 <foo-9>: pop %rbp
hi-cold:
(gdb) x/5i foo_cold
0x401128 <foo_cold>: push %rbp
0x401129 <foo+35>: mov %rsp,%rbp
0x40112c <foo+38>: callq 0x401134 <baz>
0x401131 <foo+43>: nop
0x401132 <foo+44>: pop %rbp
In both cases, the symbol shown for the address at which foo_cold
resides is shown as <foo_cold>. Subsequent offsets are shown as
either negative or positive offsets from the entry pc for foo.
When disassembling a function, care must be taken to NOT display
<+0> as the offset for the second range. For this reason, I found
it necessary to add the "prefer_sym_over_minsym" parameter to
build_address_symbolic. The type of this flag is a bool; do_demangle
ought to be a bool also, so I made this change at the same time.
gdb/ChangeLog:
* valprint.h (build_address_symbolic): Add "prefer_sym_over_minsym"
parameter. Change type of "do_demangle" to bool.
* disasm.c (gdb_pretty_print_disassembler::pretty_print_insn):
Pass suitable "prefer_sym_over_minsym" flag to
build_address_symbolic(). Don't output "+" for negative offsets.
* printcmd.c (print_address_symbolic): Update invocation of
build_address_symbolic to include a "prefer_sym_over_minsym"
flag.
(build_address_symbolic): Add "prefer_sym_over_minsym" parameter.
Restrict cases in which use of minimal symbol is preferred to that
of a found symbol. Update comments.

Prefer symtab symbol over minsym for function names in non-contiguous blocks
The discussion on gdb-patches which led to this patch may be found
here:
https://www.sourceware.org/ml/gdb-patches/2019-05/msg00018.html
Here's a brief synopsis/analysis:
Eli Zaretskii, while debugging a Windows emacs executable, found
that functions comprised of more than one (non-contiguous)
address range were not being displayed correctly in a backtrace. This
is the example that Eli provided:
(gdb) bt
#0 0x76a63227 in KERNELBASE!DebugBreak ()
from C:\Windows\syswow64\KernelBase.dll
#1 0x012e7b89 in emacs_abort () at w32fns.c:10768
#2 0x012e1f3b in print_vectorlike.cold () at print.c:1824
#3 0x011d2dec in print_object (obj=<optimized out>, printcharfun=XIL(0),
escapeflag=true) at print.c:2150
The function print_vectorlike consists of two address ranges, one of
which contains "cold" code which is expected to not execute very often.
There is a minimal symbol, print_vectorlike.cold.65, which is the address
of the "cold" range.
GDB is prefering this minsym over the the name provided by the
DWARF info due to some really old code in GDB which handles
"certain pathological cases". This comment reads as follows:
/* In certain pathological cases, the symtabs give the wrong
function (when we are in the first function in a file which
is compiled without debugging symbols, the previous function
is compiled with debugging symbols, and the "foo.o" symbol
that is supposed to tell us where the file with debugging
symbols ends has been truncated by ar because it is longer
than 15 characters). This also occurs if the user uses asm()
to create a function but not stabs for it (in a file compiled
with -g).
So look in the minimal symbol tables as well, and if it comes
up with a larger address for the function use that instead.
I don't think this can ever cause any problems; there
shouldn't be any minimal symbols in the middle of a function;
if this is ever changed many parts of GDB will need to be
changed (and we'll create a find_pc_minimal_function or some
such). */
In an earlier version of this patch, I had left the code for the
pathological case intact, but those who reviwed that patch recommended
removing it. So that's what I've done - I've removed it.
gdb/ChangeLog:
* stack.c (find_frame_funname): Remove code which preferred
minsym over symtab sym in "certain pathological cases".

[gdb/testsuite] Add missing initial prompt read in multidictionary.exp
When running multidictionary.exp in conjunction with:
...
$ stress -c $(($(cat /proc/cpuinfo | grep -c "^processor") + 1))
...
we get:
...
Running gdb/testsuite/gdb.dwarf2/multidictionary.exp ...
ERROR: Couldn't load multidictionary into gdb.
=== gdb Summary ===

...
The multidictionary test-case needs -readnow, and achieves this using:
...
gdb_spawn_with_cmdline_opts "-readnow"
gdb_load
...
but the initial gdb prompt is not read. Usually, the following gdb_load
command accidentally consumes that initial prompt (at the gdb_expect for the
kill command in gdb_file_cmd). But under high load, that doesn't happen and
we run into the error.
Fix this by consuming the initial gdb prompt after spawning gdb.

[gdb][Arm]: gdb cannot step across CMSE secure entry function code.
GDB is not able to execute "step" command on function calls of Armv8-M cmse secure entry functions.
Everytime GNU linker come across definition of any cmse secure entry function in object file(s),
it creates two new instructions secure gateway (sg) and original branch destination (b.w),
place those two instructions in ".gnu.sgstubs" section of executable.
Any function calls to these cmse secure entry functions is re-directed through secure gateway (sg)
present in ".gnu.sgstubs" section.
Example:
Following is a function call to cmse secure entry function "foo":
...
bl xxxx <foo> --->(a)
...
<foo>
xxxx: push {r7, lr}
GNU linker on finding out "foo" is a cmse secure entry function, created sg and b.w instructions and
place them in ".gnu.sgstubs" section (marked by c).
The "bl" instruction (marked by a) which is a call to cmse secure entry function is modified by GNU linker
(as marked by b) and call flow is re-directly through secure gateway (sg) in ".gnu.sgstubs" section.
...
bl yyyy <foo> ---> (b)
...
section .gnu.sgstubs: ---> (c)
yyyy <foo>
yyyy: sg // secure gateway
b.w xxxx <__acle_se_foo> // original_branch_dest
...
0000xxxx <__acle_se_foo>
xxxx: push {r7, lr} ---> (d)
On invoking GDB, when the control is at "b" and we pass "step" command, the pc returns "yyyy"
(sg address) which is a trampoline and which does not exist in source code. So GDB jumps
to next line without jumping to "__acle_se_foo" (marked by d).
The above details are published on the Arm website [1], please refer to section 5.4 (Entry functions)
and section 3.4.4 (C level development flow of secure code).
[1] https://developer.arm.com/architectures/cpu-architecture/m-profile/docs/ecm0359818/latest/armv8-m-security-extensions-requirements-on-development-tools-engineering-specification
This patch fixes above problem by returning target pc "xxxx" to GDB on executing "step"
command at "b", so that the control jumps to "__acle_se_foo" (marked by d).

SHF_GNU_MBIND requires ELFOSABI_GNU
When SHF_GNU_MBIND was added in the SHF_LOOS to SHF_HIOS range, it
should have required ELFOSABI_GNU since these flags are already in use
by other OSes. HPUX SHF_HP_TLS in fact has the same value. That
means no place in binutils should test SHF_GNU_MBIND without first
checking OSABI, and SHF_GNU_MBIND should not be set without also
setting OSABI. At least, that's the ideal, but the patch accepts
SHF_GNU_MBIND on ELFOSABI_NONE object files since gas didn't always
set OSABI. However, to reinforce the fact that SHF_GNU_MBIND isn't
proper without a non-zero OSABI, readelf will display the flag as
LOOS+0 if OSABI isn't set.
The clash with SHF_HP_TLS means that hppa64-linux either has that flag
on .tbss sections or supports GNU_MBIND, not both. (hppa64-linux
users, if there are any, may have noticed that GNU ld since 2017
mysteriously aligned their .tbss sections to a 4k boundary. That was
one consequence of SHF_HP_TLS being blindly interpreted as
SHF_GNU_MBIND.) Since it seems that binutils, gdb, gcc, glibc, and
the linux kernel don't care about SHF_HP_TLS I took that flag out of
.tbss for hppa64-linux.

[gdb/testsuite] Fix command result testing in mi-complete.exp
When running gdb.mi/mi-complete.exp in conjunction with:
...
$ stress -c $(($(cat /proc/cpuinfo | grep -c "^processor") + 1))
...
we get less than 50% full passes:
...
$ for n in $(seq 1 100); do \
make V=1 -O check \
'RUNTESTFLAGS=gdb.mi/mi-complete.exp --target_board=unix'; \
done 2>&1 \
| grep "expected passes" | sort | uniq -c
45 # of expected passes 7
9 # of expected passes 8
46 # of expected passes 9
...
A diff between a passing and failing gdb.log shows this difference:
...
-&"set max-completions 1\n"
2-complete br
+&"set max-completions 1\n"
...
The problem is that the test-case issues the "set max-completion <n>" command,
and without waiting for the output issues a next command, and tries to parse
the results of both commands, expecting a specific interleaving of the various
output streams.
Fix the FAIL by waiting for the result of the "set max-completion <n>" command
before issuing another command.
Tested on x86_64-linux.

This patch addresses the change in the June Armv8.1-M Mainline specification, that marks certain MVE instructions as no longer UNPREDICTABLE when a source operand is the same as a destination operand for a 32-bit element size.
The instructions that this change apply to are:
VQDMLADH, VQRDMLADH, VQDMLSDH, VQRDMLSDH
The updated documentation is here: https://static.docs.arm.com/ddi0553/bh/DDI0553B_h_armv8m_arm.pdf
Fixed this by removing the check for this warning from GAS as well as opcodes.
Added testcases to test that the warning is not generated for the instructions that have a 32-bit element size
and the same source and destination operand. Also fixed tests that would previously check for this warning.

gdb: Show type summary for anonymous structures from c_print_typedef
Currently each language has a la_print_typedef method, this is only
used for the "info types" command.
The documentation for "info types" says:
Print a brief description of all types whose names match the regular
expression @var{regexp} (or all types in your program, if you supply
no argument).
However, if we consider this C code:
typedef struct {
int a;
} my_type;
Then currently with "info types" this will be printed like this:
3: typedef struct {
int a;
} my_type;
I see two problems with this, first the indentation is clearly broken,
second, if the struct contained more fields then it feels like the
actual type names could easily get lost in the noise.
Given that "info types" is about discovering type names, I think there
is an argument to be made that we should focus on giving _only_ the
briefest summary for "info types", and if the user wants to know more
they can take the type name and plug it into "ptype". As such, I
propose that a better output would be:
3: typedef struct {...} my_type;
The user understands that there is a type called `my_type`, and that
it's an alias for an anonymous structure type.
The change to achieve this turns out to be pretty simple, but only
effects languages that make use of c_print_typedef, which are C, C++,
asm, minimal, d, go, objc, and opencl. Other languages will for now
do whatever they used to do.
The patch to change how anonymous structs are displayed also changes
the display of anonymous enums, consider this code sample:
typedef enum {
AA, BB, CC
} anon_enum_t;
This used to be displayed like this:
3: typedef enum {AA, BB, CC} anon_enum_t;
Which will quickly become cluttered for enums with a large number of
values. The modified output looks like this:
3: typedef enum {...} anon_enum_t;
Again, the user can always make use of ptype if they want to see the
details of the anon_enum_t type.
It is worth pointing out that this change (to use {...}) only effects
anonymous structs and enums, named types don't change with this patch,
consider this code:
struct struct_t {
int i;
};
enum enum_t {
AA, BB, CC
};
The output from 'info types' remains unchanged, like this:
4: enum enum_t;
1: struct struct_t;
An additional area of interest is how C++ handles anonymous types used
within a typedef; enums are handled basically inline with how C
handles them, but structs (and classes) are slightly different. The
behaviour before the patch is different, and is unchanged by this
patch. Consider this code compiled for C++:
typedef struct {
int i;
} struct_t;
Both before and after this patch, this is show by 'info types' as:
3: typedef struct_t struct_t;
Unions are displayed similarly to structs in both C and C++, the
handling of anonymous unions changes for C in the same way that
it changes for anonymous structs.
I did look at ada, as this is the only language to actually have some
tests for "info types", however, as I understand it ada doesn't really
support typedefs, however, by forcing the language we can see what ada
would print. So, if we 'set language ada', then originally we printed
this:
3: record
a: int;
end record
Again the indentation is clearly broken, but we also have no mention
of the type name at all, which is odd, but understandable given the
lack of typedefs. If I make a similar change as I'm proposing for C,
then we now get this output:
3: record ... end record
Which is even less informative I think. However, the original output
_is_ tested for in gdb.ada/info_auto_lang.exp, and its not clear to me
if the change is a good one or not, so for now I have left this out.

type_print.

gdb: Improve output from "info types" commad
This commit makes two changes to the "info types" command:
First, only use typedef_print for printing typedefs, and use
type_print for printing non-typedef scalar (non-struct) types. The
result of this is the output for builtin types goes from this:
typedef double;
typedef float;
typedef int;
to this:
double;
float;
int;
which seems to make more sense.
Next GDB no longer matches msymbols as possible type names. When
looking for function symbols it makes sense to report matching
msymbols from the text sections, and for variables msymbols from the
data/bss sections, but when reporting types GDB would match msymbols
of type absolute. But I don't see why these are likely to indicate
type names. As such I've updated the msymbol matching lists in
symtab.c:search_symbols so that when searching in the TYPES_DOMAIN, we
never match any msymbols.
gdb/ChangeLog:
* symtab.c (search_symbols): Adjust msymbol matching type arrays
so that GDB doesn't match any msymbols when searching in the
TYPES_DOMAIN.
(print_symbol_info): Print using typedef_print or type_print based
on the type of the symbol. Add updated FIXME comment moved from...

Make documentation of "python" command match actual behavior
The example in the documentation for the "python" command shows GDB
outputting instructions for how to terminate a sequence of python
commands entered from the command line. The documentation shows that
the following two lines are being output, though this does not occur
when actually using the "python" command from GDB:
Type python script
End with a line saying just "end".
While display of this text might be helpful, GDB has several other
commands which also use the "end" terminator that offer no such text.
Examples include the "if" and "while" commands. For example,
(gdb) if 1==1
>print "a"
>end
$1 = "a"
This seems similar to doing:
(gdb) python
>print 23
>end
23
If we decide that we want the "python" command to print such a message,
we should also adjust the behavior for other GDB commands which also use
"end" to terminate a command list. I.e, if this decision is made, the
"if" and "while" commands ought to also print similar messages.
So, for the moment anyway, this commit adjusts the documentation of the
python command to match its implementation.
This patch was taken from a larger body of work originating from the
Archer project. I haven't been able to determine its original author,
though I did find a commit log from Jan Kratochvil (in the Archer
repository) which suggests that the change had originally been made to
gdb.texinfo, but got inadvertently dropped when the python related
documentation was split out to python.texi.
gdb/doc/ChangeLog:
* python.texi (python command): Revise example to match
command behavior.

gdb/riscv: Write 4-byte nop to dummy code region before inferior calls
When making inferior function calls GDB sets up a dummy code region on
the stack, and places a breakpoint within that region. If the random
stack contents appear to be a compressed instruction then GDB will
place a compressed breakpoint, which can cause problems if the target
doesn't support compressed instructions.
This commit prevents this issue by writing a 4-byte nop instruction to
the dummy region at the time the region is allocated. With this nop
instruction in place, when we come to insert the breakpoint then an
uncompressed breakpoint will be used.
This is similar to other targets, for example mips.

patch updates some text to reflect this change.
I also noticed that a few rules can be removed now. ARGSUSED doesn't

cpu,opcodes,gas: use %r0 and %r6 instead of %a and %ctf in eBPF disassembler
This patch changes the eBPF CPU description to prefer the register
names %r0 and %r6 instead of %a and %ctx when disassembling. This
matches better with the current practice, vs. cBPF.
It also updates the GAS tests in order to reflect this change.
Tested in a x86_64 host.

[AArch64] Rename +bitperm to +sve2-bitperm
After some discussion, we've decided to rename the +bitperm feature
flag to +sve2-bitperm, so that it's consistent with the other SVE2
feature flags. The associated internal macros already used
"SVE2_BITPERM", so only the feature flag itself needs to change.

[PowerPC64] pc-relative TLS relocations
This patch supports using pcrel instructions in TLS code sequences. A
number of new relocations are needed, gas operand modifiers to
generate those relocations, and new TLS optimisation. For
optimisation it turns out that the new pcrel GD and LD sequences can
be distinguished from the non-pcrel GD and LD sequences by there being
different relocations on the new sequence. The final "add ra,rb,13"
on IE sequences similarly needs a new relocation, or as I chose, a
modification of R_PPC64_TLS. On pcrel IE code, the R_PPC64_TLS points
one byte into the "add" instruction rather than being on the
instruction boundary.

libctf: introduce ctf_func_type_{info,args}, ctf_type_aname_raw
The first two of these allow you to get function type info and args out
of the types section give a type ID: astonishingly, this was missing
from libctf before now: so even though types of kind CTF_K_FUNCTION were
supported, you couldn't find out anything about them. (The existing
ctf_func_info and ctf_func_args only allow you to get info about
functions in the function section, i.e. given symbol table indexes, not
type IDs.)
The second of these allows you to get the raw undecorated name out of
the CTF section (strdupped for safety) without traversing subtypes to
build a full C identifier out of it. It's useful for things that are
already tracking the type kind etc and just need an unadorned name.

Fix for using named pipes on Windows
On Windows, passing a named pipe as terminal argument to the new-ui
command does not work.
The problem is that the new_ui_command function in top.c opens the
same tty three times, for stdin, stdout and stderr. With Windows
named pipes, the second and third calls to open fail.
Opening the file only once and passing the same stream for stdin,
stdout and stderr makes it work.
Pedro says:
I tried it on GNU/Linux and things still work.
I ran all the MI tests with forced new-ui, with:
$ make check TESTS="gdb.mi/*.exp" RUNTESTFLAGS="FORCE_MI_SEPARATE_UI=1"
and saw no regressions.

Rearrange TUI data window code
An earlier patch caused tui-windata.h to be essentially empty. And,
other earlier patches implemented TUI data window methods in any spot
that happened to be convenient at the time.
This patch rearranges all the data window code to be somewhat more
organized. It moves tui_data_window to tui-regs.h, and moves the
implementation of all methods to tui-regs.c. It then removes
tui-windata.h and tui-windata.c.
It also removes the "structuring" comments from tui-regs.c; these are
not the usual gdb style, and were out of date anyhow. Finally, it
moves _initialize_tui_regs to the end of the file, per the usual gdb
convention.

Fix flushing bug in tui_puts_internal
A while back I changed gdb not to flush in some places. It turned out
that this broke the TUI a little. An easy way to see it is to run
"gdb -tui -nx", then "file gdb" at the gdb prompt. gdb will print the
usual "Reading symbols..." message -- but it won't appear on-screen
until the reading is complete.
This patch changes the TUI to do the equivalent of line buffering in
tui_puts_internal.

Always create an execution info window for a source window
A source or disassembly window will always have an "execution info"
window (the window along the side that displays breakpoint info), but
this isn't immediately clear from the source. As a result, some code
has checks to see whether the execution_info is NULL.
This changes the source window base class to always instantiate an
execution_info window, then updates the rest of the code. It also
simplifies window creation in tui-layout.c.

Remove some dead code from tui_set_layout
tui_set_layout sets regs_populate using:

Remove TUI data window special case
The TUI has a couple of special cases for updating the data window:
one in tui_rl_other_windowand one in tui_set_focus_command. As part
of the project to remove references to globals, I wanted to remove
these calls; but when I did, some simple operations (like "C-x o")
would cause the register window to blank.
This fixes the underlying problem by arranging for the data window's
refresh_window method to call the superclass method first, and then to
refresh the child windows. Then the special cases can be removed.

Simplify source window clearing
When a TUI source window is empty, it displays a "No Source Available"

Move content_in_use to tui_source_window class
From scanning the source now, it's clear that the content_in_use field
is only used for the source window. This patch moves the field there,
and changes it to be a bool at the same time. (A future patch will
clean this up further, removing the field entirely.)

gdb: Remove a non-const reference parameter
Non-const reference parameter should be avoided according to the GDB
coding standard:
https://sourceware.org/gdb/wiki/Internals%20GDB-C-Coding-Standards#Avoid_non-const_reference_parameters.2C_use_pointers_instead
This commit updates the gdbarch method gdbarch_stap_adjust_register,
and the one implementation i386_stap_adjust_register to avoid using a
non-const reference parameter.
I've also removed the kfail from the testsuite for bug 24541, as this
issue is now resolved.

x86: replace "anymem" checks where possible
Once operand parsing has completed, the simpler check of Operand_Mem can
be used in places where i.types[] got passed to operand_type_check().
Note that this has shown a couple of omissions of adjusting i.flags[]
when playing with i.op[] / i.types[] / i.tm.operand_types[]. Not all of
them get added here, just all of the ones needed in process_operands().

x86: drop stale Mem enumerator
This was supposed to also be removed by c48dadc9a8 ('x86: drop "mem"
operand type attribute'). It's odd enough that this hasn't caused
build issues, considering the careful use of OTunused (apparently to
avoid "missing initializer" warnings).
To avoid such happening again introduce compile time consistency
checks.

x86: make RegMem an opcode modifier
... instead of an operand type bit: It's an insn property, not an
operand one. There's just one actual change to be made to the
templates: Most are now required to have the (unswapped) destination go
into ModR/M.rm, so VMOVD template needs its opcode adjusted accordingly
and its operands swapped. {,V}MOVS{S,D}, otoh, are left alone in this
regard, as otherwise generated code would differ from what we've been
producing so far (which I don't think is wanted).
Take the opportunity and add a missing IgnoreSize to pextrb (leading to
an error in 16-bit mode), and take the liberty to once again drop stray
IgnoreSize attributes from lines changed and neighboring related ones.

x86: fold SReg{2,3}
They're the only exception to there generally being no mix of register
kinds possible in an insn operand template, and there being two bits per
operand for their representation is also quite wasteful, considering the
low number of uses. Fold both bits and deal with the little bit of
fallout.
Also take the liberty and drop dead code trying to set REX_B: No segment
register has RegRex set on it.
Additionally I was quite surprised that PUSH/POP with the permitted
segment registers is not covered by the test cases. Add the missing
pieces.

Fix __bss_start assertion failure in _bfd_elf_fix_symbol_flags

> issue has been filed in FreeBSD's bugzilla, at
> https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=237068 . It appears

I haven't looked under a debugger at your testcase but I think I know
what is going on here. You have a shared library with a weakly
defined llvm::hashing::detail::get_execution_seed()::seed which
happens to be at the same location as __bss_start in that library. At
the time the linker loads symbols for that library, it sees they are
both versioned and thus introduces non-versioned indirect symbols for
them. The linker considers the symbols as possibly being aliases,
setting up h->u.alias and h->is_weakalias such that
__bss_start@@JL_LLVM_6.0 is the definition. No real problem so far,
the definition is bfd_link_hash_defined, except that the zero size, no
type __bss_start symbol possibly should not be considered an alias in
the first place.
Later, __bss_start as defined by the linker script is entered into the
linker symbol table. This is similar to __bss_start being defined by
a regular object file in that ELF symbol resolution rules say that the
value of __bss_start in the library is overridden by __bss_start in
the executable/library being produced. So to accomplish the override,
ld flips __bss_start from being an indirect symbol pointing at
__bss_start@@JL_LLVM_6.0 to __bss_start@@JL_LLVM_6.0 being an indirect
symbol pointing at __bss_start. That's how we get an unexpected
indirect symbol and hit the assert.
What should happen I think, is for the def->def_regular code above the
assert to run in this case. The symbols are no longer aliases.
* elflink.c (_bfd_elf_fix_symbol_flags): If the def for an
alias is no longer bfd_link_hash_defined, clear the alias.

cpu,opcodes,gas: fix arguments to ldabs and ldind eBPF instructions
The eBPF non-generic load instructions ldind{b,h,w,dw} and
ldabs{b,h,w,dw} do not take an explicit destination register as an

adjust src-release following the renaming of gdb/common/ to gdb/gdbsupport/
A recent change renamed the common/ directory into gdbsupport/ in gdb.
This causes problems in the getver function in the src-release script
which doesn't find the create-version.sh script anymore. As a result,
it falls back on using the version.in file verbatim, meaning that
the "DATE" placeholder doesn't get replaced with the snapshot date,
and the "-git" suffix doesn't get stripped. More precisely, we get
snapshots called "gdb-8.3.50-DATE-git.tar" instead of (e.g.)
"gdb-8.3-20190712.tar".
This commit fixes the issue by adding support for this situation.
I left the support for $tool/common/create-version.sh, because
the sim still uses that directory structure.
ChangeLog:
* src-release (getver): If $tool/gdbsupport/create-version.sh
exists, use that to determine the version number.

Dynamic TLS section symbols
It is possible to create shared libraries on PowerPC using
-ftls-model=inital-exec or -ftls-model=local-exec. The first is half
reasonable, getting you a shared library that can't be dlopen'd but
otherwise is reasonable. The second is quite bad. Not only do you
lose being able to dlopen, the library also has dynamic text
relocations. Worse, the TPREL16_LO, TPREL16_HA and other TPREL16
dynamic relocs emitted were wrong, resulting in wrong values being
applied by ld.so.
Using the first TLS section symbol in dynamic relocations for local
TLS symbols doesn't work. It's wrong because TLS symbols used by TLS
relocs have values relative to the TLS segment, whereas the TLS
section symbols are addresses. This patch instead uses a symbol index
of zero which is used elsewhere by PowerPC on dynamic TLS relocs.
It's not strictly ABI compliant to use a non-TLS symbol with TLS
relocs but symbol index zero can be interpreted as "no symbol". Not
using the first TLS section symbol means it doesn't need to be dynamic.
The patch also fixes a further problem with PowerPC32 dynamic TPREL16*
relocs, which shouldn't have the symbol value in the addend as we do
for non-TLS symbols.

[GOLD] PowerPC notoc eh_frame
When generating notoc call and branch stubs without the benefit of
pc-relative insns, the stubs need to use LR to access the run time PC.
All LR changes must be described in .eh_frame if we're to support
unwinding through asynchronous exceptions. That's what this patch
does.
The patch has gone through way too many iterations. At first I
attempted to add multiple FDEs, one for each stub. That ran into
difficulties with do_plt_fde_location which is only capable of setting
the address of a single FDE per Output_data section, and with removing
any FDEs added on a previous do_relax pass. Removing FDEs (git commit
be897fb774) went overboard in matching the FDE contents. That means
either stashing the contents created for add_eh_frame_for_plt to use
when calling remove_eh_frame_for_plt, or recreating contents on the
fly (*) just to remove FDEs. In fact, FDE content matching is quite
unnecesary. FDEs added by a previous do_relax pass are those with
u_.from_linker.post_map set. So they can easily be recognised just by
looking at that flag. This patch keeps that part of the multiple FDE
changes.
In the end I went for just one FDE per stub group to describe the call
stubs. That's reasonably efficient for the common case of only
needing to describe the __tls_get_addr_opt call stub. We don't expect
to be making many calls using notoc stubs without pc-relative insns.
*) Which has it's own set of problems. The contents must be recreated
using the old stub layout, but .eh_frame size can affect stub
requirements so you need to temporarily keep the old .eh_frame size
when creating new stubs, then reset .eh_frame size before adding new
FDEs.

gdb: Carry default property type around with dynamic properties
This commit is preparation for the next one, with the aim of better
supporting signed dynamic properties on targets where the address size
specified in the DWARF headers is smaller than a CORE_ADDR, for
example debugging an i386 application on x86-64.
Consider this small Fortran program 'bounds.f90':
program test
integer, allocatable :: array (:)
allocate (array (-5:5))
array(3) = 1
end program test
Compiled with 'gfortran -m32 -g3 -O0 -o bounds bounds.f90'. The DWARF
for 'array' looks like this:
<2><97>: Abbrev Number: 10 (DW_TAG_variable)
<98> DW_AT_name : (indirect string, offset: 0x0): array
<9c> DW_AT_decl_file : 1
<9d> DW_AT_decl_line : 2
<9e> DW_AT_type : <0xaf>
<a2> DW_AT_location : 2 byte block: 91 58 (DW_OP_fbreg: -40)
<2><a5>: Abbrev Number: 11 (DW_TAG_lexical_block)
<a6> DW_AT_low_pc : 0x80485c3
<aa> DW_AT_high_pc : 0x8b
<2><ae>: Abbrev Number: 0

<b0> DW_AT_data_location: 2 byte block: 97 6 (DW_OP_push_object_address; DW_OP_deref)
<b3> DW_AT_allocated : 4 byte block: 97 6 30 2e (DW_OP_push_object_address; DW_OP_deref; DW_OP_lit0; DW_OP_ne)
<b8> DW_AT_type : <0x2a>
<2><bc>: Abbrev Number: 13 (DW_TAG_subrange_type)
<bd> DW_AT_lower_bound : 4 byte block: 97 23 10 6 (DW_OP_push_object_address; DW_OP_plus_uconst: 16; DW_OP_deref)
<c2> DW_AT_upper_bound : 4 byte block: 97 23 14 6 (DW_OP_push_object_address; DW_OP_plus_uconst: 20; DW_OP_deref)
<c7> DW_AT_byte_stride : 6 byte block: 97 23 c 6 34 1e (DW_OP_push_object_address; DW_OP_plus_uconst: 12; DW_OP_deref; DW_OP_lit4; DW_OP_mul)
<2><ce>: Abbrev Number: 0
If we look at the DW_AT_lower_bound attribute, which will become a
dynamic property that GDB evaluates when needed by calling
dwarf2_evaluate_property.
The process of evaluating a dynamic property requires GDB to execute
each DW_OP_* operation, the results of these operations is held on a
stack of 'struct value *'s.
When the entire expression is evaluated the result is on top of the
stack.
If we look at DW_AT_lower_bound then the last operation is
DW_OP_deref, this loads a signed address the size of which matches the
DWARF address size, and so in our i386 on x86-64 situation, the top of
the stack will be a signed 4-byte value.
The problem is how these values are fetched from the stack. Currently
they are always fetched by a call to dwarf_expr_context::fetch_address,
which converts the value to an unsigned value with a length matching
the values current length, before converting to a CORE_ADDR. This
means we loose the signed nature of the property.
I wonder if the best solution for dealing with signed properties will
be to move away from an over reliance on fetch_address, and instead
come up with a new solution that considers the current type of the
value on the stack, and the type that the value needs to become;
basically a solution built around casting rather than assuming we
always want an address.
However, before we can start to even think about moving away from
fetch_address, there is a more urgent issue to fix, which is we don't
currently know what type each property should be. We just hold the
value of the property in a CORE_ADDR as returned by fetch_address, and
rely on higher level code (outside of the DWARF expression evaluation
code) to fix things up for us. This is what this patch aims to
address.
When creating a dynamic property (see attr_to_dynamic_prop in
dwarf2read.c) we can sometimes figure out the type of a property; if
the property is a reference to another DIE then it will have a
DW_AT_type attribute.
However, the DW_AT_lower_bound case above isn't a reference to another
DIE, it's just a DWARF expression. We don't have any indication for
what type the property should have.
Luckily, the DWARF spec helps us out, for the lower and upper bounds
5.13 of the DWARFv5 spec tells us that without any other type
information the bounds are signed integers the same size as a DWARF
address.
It is my belief that we can find a suitable default type for every
dynamic property, either specified explicitly in the DWARF spec, or we
can infer an obvious choice if the spec doesn't help us.
This commit extends the creation of all dynamic properties to include
suggesting a suitable default type, all dynamic properties now always
carry their type around with them.
In later commits we can use this property type to ensure that the
value we extract from the DWARF stack is handled in a suitable manor
to correctly maintain its sign extension.
There should be no user visible changes from this commit. The actual
fix to correctly support negative array bounds will come later.
gdb/ChangeLog:
* dwarf2loc.c (dwarf2_evaluate_property): Update to take account
of changes to field names, and use new is_reference field to
decide if a property is a reference or not.
* dwarf2loc.h (struct dwarf2_locexpr_baton): Add 'is_reference'
field.

'referenced_type' to 'property_type' and update comments.

gdb/dwarf: Ensure the target type of ranges is not void
If a DW_TAG_subrange_type DWARF entry has no DW_AT_type then a default
type based on the size of an address on the current target is assumed.
We store this type as the target type for GDB's range types.
Currently GDB can create ranges for which the target type is VOID,
this is incorrect but seems to cause no problems. I believe the reason
this doesn't cause any issues is because the languages (for example
Ada) that actually make use of a ranges target type also have
compilers that generate DWARF that includes a DW_AT_type attribute.
However, gfortran does not include a DW_AT_type, its DWARF instead
relies on the default target type. This isn't currently a problem for
GDB as gfortran doesn't make use of the target type when printing
subranges, but it shouldn't hurt to fix this issue now.
I've added an assert into create_range_type that will catch this issue
if it comes up again.
This was tested on an x86-64/GNU-Linux machine with both the Ada and
gfortran compilers available with both '--target_board=unix' and
'--target_board=unix/-m32'. There are no user visible changes after
this commit.
gdb/ChangeLog:
* dwarf2read.c (read_subrange_index_type): New function.
(read_subrange_type): Move code into new function and call it.
* gdbtypes.c (create_range_type): Add some asserts.

that range bounds are handled they are held in a LONGEST, however in
value_subscripted_rvalue the bound is placed into an int.

I've written an assert in rl_redisplay that formulates the error condition:

which triggers without needing the address sanitizer (or even an executable),
like this:

`last_lmargin + (_rl_screenwidth + visible_wrap_offset) <= line_size'
failed.
Aborted (core dumped)
...
The basic problem is this: visible_line and invisible_line have length
line_size, but the update_line call assumes that line_size is at least
_rl_screenwidth + 1. Executing "set width 0" sets _rl_screenwidth to 32766 but
doesn't affect line_size, which is initialized to 1024.
Fix this by ensuring in init_line_structures and rl_redisplay that line_size
is at least _rl_screenwidth + 1.
Tested on x86_64-linux.

gdb: Add command completers for some info commands
Add command completion for info variables, functions, args, and

these commands all take a regexp which GDB can't really offer
completions for.

gdb: Allow quoting around string options in the gdb::option framework
Currently string options must be a single string with no whitespace,
this limitation prevents the gdb::option framework being used in some
places.
After this commit, string options can be quoted in single or double
quotes, and quote characters can be escaped with a backslash if needed
to either place them within quotes, or to avoid starting a quoted
argument.
This test adds a new function extract_string_maybe_quoted which is
basically a copy of extract_arg_maybe_quoted from cli/cli-utils.c,
however, the cli-utils.c function will be deleted in the next commit.
There are tests to exercise the new quoting mechanism.

* cli/cli-option.c (parse_option): Use extract_string_maybe_quoted
to extract string arguments.

Remove init_cli_cmds
I noticed that init_cli_cmds only installs a command, and so doesn't
need to be handled specially. This patch merges it into
_initialize_cli_cmds.
The help text is constructed dynamically, which is sometimes an
indication that special treatment is needed; but in this case it is
just to insert the value of "gdbinit", which is created at
compile-time and not modified; so this doesn't affect the result.
This version also removes the "gdbinit" global. There's no need for
it, as GDBINIT can be used instead. Note, though, that the help text
in question must still be dynamically constructed, in order to be
i18n-friendly.

Don't include gdbarch.h from defs.h
I touched symtab.h and was surprised to see how many files were
rebuilt. I looked into it a bit, and found that defs.h includes
gdbarch.h, which in turn includes many things.
gdbarch.h is only needed by a minority ofthe files in gdb, so this
patch removes the include from defs.h and updates the fallout.
I did "wc -l" on the files in build/gdb/.deps; this patch reduces the
line count from 139935 to 137030; so there are definitely future
build-time savings here.
Note that while I configured with --enable-targets=all, it's possible
that some *-nat.c file needs an update. I could not test all of
these. The buildbot caught a few problems along these lines.

Specialize value_cast error message for Ada
In Ada, the term for a cast is "type conversion". AdaCore has been
carrying a local patch to specialize the error message in value_cast,
but it seemed fine to me for this to be part of gdb. This also
removes a dead "return" statement.

arm-dis.c (print_insn_coprocessor): Rename index to index_operand.
Older gcc warns, arguably incorrectly, about name collisions between
global functions and function-local variable names. Consesus has been
to rename local variables whenever this is spotted, hence committed as
obvious. Note the pre-existing variable named idx; "index_operand"
seemed logical given the context.
* arm-dis.c (print_insn_coprocessor): Rename index to
index_operand.

Restore original GDB prompt in define.exp
define.exp will fail on a GDB which has set a custom prompt to identify
itself. This is because the test resets the prompt to a hard coded
"(gdb)" but then verifies the success of this against the value in
$gdb_prompt, which is set to the custom prompt.
The original approach to fix this involved resetting the prompt to
$gdb_prompt rather than a hard coded "(gdb)". However it was noted during
review that $gdb_prompt is a regular expression rather than a string.
This is problematic because in general the prompt would be reset to a
regular expression rather than an instance of a string accepted by said
regular expression.
The fix used in this commit avoids the above issue by capturing the
literal prompt from running "show prompt" and uses this literal to
restore the previous prompt.
Regression tested with GCC 7.3.0 on x86_64, ppc64le, aarch64.

Make "maint info breakpoints" show "catch catch/throw/rethrow" locations
This commit makes "maint info breakpoints" show the internal locations
of C++ exception catchpoints:
(gdb) info breakpoints
Num Type Disp Enb Address What
2 catchpoint keep y exception catch
With multiple locations:
(gdb) maint info breakpoints
Num Type Disp Enb Address What
2 catchpoint keep y exception catch
2.1 y 0x000000000040545f <__cxa_begin_catch+95> inf 1
2.2 y 0x00007ffff71dbe0f <__cxxabiv1::__cxa_begin_catch(void*)+95> inf 1
(gdb)
With a single location:
(gdb) maint info breakpoints 2
Num Type Disp Enb Address What
2 catchpoint keep y exception catch inf 1
2.1 y 0x00007ffff7bc0b7f <__cxa_begin_catch+95> inf 1
With no locations:
(gdb) maint info breakpoints 2
Num Type Disp Enb Address What
2 catchpoint keep y exception catch inf 1
Other catchpoints still show the same way, here a catch signal:
(gdb) info breakpoints
Num Type Disp Enb Address What
3 catchpoint keep y signal "<standard signals>"
(gdb) maint info breakpoints
Num Type Disp Enb Address What
3 catchpoint keep y signal "<standard signals>" inf 1
(gdb)
Note: I considered making the locations be printed from within
breakpoint_ops::print_one(), but gave up given the handling for the
broken MI v2 output:
/* The mi2 broken format: the main breakpoint tuple ends here, the locations
are outside. */
if (!use_fixed_output)

"catch catch/throw/rethrow", breakpoint -> catchpoint
Currently, with:
(gdb) catch catch
Catchpoint 1 (catch)
(gdb) catch throw
Catchpoint 2 (throw)
(gdb) catch rethrow
Catchpoint 3 (rethrow)
You get:
(gdb) info breakpoints
Num Type Disp Enb Address What
1 breakpoint keep y 0x0000000000b122af exception catch
2 breakpoint keep y 0x0000000000b1288d exception throw
3 breakpoint keep y 0x0000000000b12931 exception rethrow
I think it doesn't make much sense usability-wise, to show a
catchpoint as a breakpoint. The fact that GDB sets a breakpoint at
some magic address in the C++ run time is an implementation detail,
IMO. And as seen in the previous patch, such a catchpoint can end up
with more than one location/address even, so showing a single address
isn't entirely accurate.
This commit hides the addresses from view, and makes GDB show
"catchpoint" for type as well:
(gdb) info breakpoints
Num Type Disp Enb Address What
1 catchpoint keep y exception catch
2 catchpoint keep y exception throw
3 catchpoint keep y exception rethrow
This comment in the code seems telling:
/* We need to reset 'type' in order for code in breakpoint.c to do
the right thing. */
cp->type = bp_breakpoint;
It kind of suggests that the reason catchpoints end up shown as
breakpoints was that it was easier to implement them that way, rather
than a desired property.
This commit fixes things up to make it possible to have bp_catch
breakpoints have software/hardware breakpoint locations, thus
eliminating the need for that hack:
- redo breakpoint_address_is_meaningful in terms of the location's
type rather than breakpoint type.
- teach bpstat_what about stepping over the catchpoint locations.
- install a allocate_location method for "catch catch/throw/rethrow",
one that forces the location type.
Note that this also reverts the gdb hunk from:

Fix "info break" + "catch catch" + -static-{libstdc++,libgcc}
If you debug current GDB, set a "catch catch/throw/rethrow"
catchpoint, and then do "info breakpoints", the top GDB hits an
internal error:
(top-gdb) catch catch
Catchpoint 1 (catch)
(top-gdb) info breakpoints
Num Type Disp Enb Address What
1 breakpoint keep y src/gdb/breakpoint.c:6040: internal-error: void print_one_breakpoint_location(breakpoint*, bp_location*, int, bp_location**, int): Assertion `b->loc == NULL || b->loc->next == NULL' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
The assertion in question is asserting that a breakpoint with a
print_one method only has one location, and it fails because this
catchpoint ends up with two locations.
Internally, "catch catch" sets a breakpoint at __cxa_begin_catch. If
we do that manually, we see the locations:
(top-gdb) b -qualified __cxa_begin_catch
Breakpoint 2 at 0xb122b0 (2 locations)
(top-gdb) info breakpoints
Num Type Disp Enb Address What
2 breakpoint keep y <MULTIPLE>
2.1 y 0x0000000000b122b0 <__cxa_begin_catch>
2.2 y 0x00007ffff2f4ddb0 in __cxxabiv1::__cxa_begin_catch(void*) at ../../../../libstdc++-v3/libsupc++/eh_catch.cc:41
Note that I had used -qualified. It seems strange that we get a
location for a namespaced symbol, but that happens because the minimal
symbol for that address is indeed called __cxa_begin_catch.
The real issue is that gdb is linked with
-static-libgcc/-static-libstdc++. And then, it _also_ ends up with
shared libstc++ loaded:
(top-gdb) info sharedlibrary stdc++
From To Syms Read Shared Object Library
0x00007ffff2f4b380 0x00007ffff2ffc018 Yes /lib64/libstdc++.so.6
Location 2.2 is set within libstdc++.so.6's range:
(top-gdb) p 0x00007ffff2f4b380 <= 0x00007ffff2f4ddb0 && 0x00007ffff2f4ddb0 < 0x00007ffff2ffc018
$1 = true
So due to -static-lib*, we end up with _two_ copies of the
__cxa_begin_catch code:
(top-gdb) disassemble 0x0000000000b122b0
Dump of assembler code for function __cxa_begin_catch:
0x0000000000b122b0 <+0>: push %rbx
0x0000000000b122b1 <+1>: mov %rdi,%rbx
0x0000000000b122b4 <+4>: callq 0xb11a80 <__cxa_get_globals>
0x0000000000b122b9 <+9>: movabs $0xb8b1aabcbcd4d500,%rdx
...
(top-gdb) disassemble 0x00007ffff2f4ddb0
Dump of assembler code for function __cxxabiv1::__cxa_begin_catch(void*):
0x00007ffff2f4ddb0 <+0>: push %rbx
0x00007ffff2f4ddb1 <+1>: mov %rdi,%rbx
0x00007ffff2f4ddb4 <+4>: callq 0x7ffff2f4a090 <__cxa_get_globals@plt>
0x00007ffff2f4ddb9 <+9>: movabs $0xb8b1aabcbcd4d500,%rdx
...
I think we end up with libstdc++.so.6 loaded because
libsource-highlight.so depends on it.
Irrespective of whether it's a good idea to use
-static-libgcc/-static-libstdc++, GDB should not crash. Since there
are two copies of the code, it seems right to have more than one
location. So the fix is just to remove the assertion.
A testcase is included, which mimics the scenerio described above,
with binary linked with -static-lib{stdc++,gcc} and a shared library
that is linked normally, along with other combinations for good
measure.

Rename common to gdbsupport
This is the next patch in the ongoing series to move gdbsever to the
top level.
This patch just renames the "common" directory. The idea is to do
this move in two parts: first rename the directory (this patch), then
move the directory to the top. This approach makes the patches a bit
more tractable.
I chose the name "gdbsupport" for the directory. However, as this
patch was largely written by sed, we could pick a new name without too
much difficulty.

gdb: Don't skip prologue for explicit line breakpoints in assembler
It was observed that in some cases, placing a breakpoint in an
assembler file using filename:line-number syntax would result in the
breakpoint being placed at a different line within the file.
For example, consider this x86-64 assembler:
test:
push %rbp /* Break here. */
mov %rsp, %rbp
nop /* Stops here. */
The user places the breakpoint using file:line notation targeting the
line marked 'Break here', GDB actually stops at the line marked 'Stops
here'.
The reason is that the label 'test' is identified as the likely start
of a function, and the call to symtab.c:skip_prologue_sal causes GDB
to skip forward over the instructions that GDB believes to be part of
the prologue.
I believe however, that when debugging assembler code, where the user
has instruction-by-instruction visibility, if they ask for a specific
line, GDB should (as far as possible) stop on that line, and not
perform any prologue skipping. I don't believe that the behaviour of
higher level languages should change, in these cases skipping the
prologue seems like the correct thing to do.
In order to implement this change I needed to extend our current
tracking of when the user has requested an explicit line number. We
already tracked this in some cases, but not in others (see the changes
in linespec.c). However, once I did this I started to see some
additional failures (in tests gdb.base/break-include.exp
gdb.base/ending-run.exp gdb.mi/mi-break.exp gdb.mi/mi-reverse.exp
gdb.mi/mi-simplerun.exp) where we currently expected a breakpoint
placed at one file and line number to be updated to reference a
different line number, this was fixed by removing some code in
symtab.c:skip_prologue_sal. My concern here is that removing this
check didn't cause anything else to fail.
I have a new test that covers my original case, this is written for
x86-64 as most folk have access to such a target, however, any
architecture that has a prologue scanner can be impacted by this
change.
gdb/ChangeLog:
* linespec.c (decode_digits_list_mode): Set explicit_line to a
bool value.
(decode_digits_ordinary): Set explicit_line field in sal.
* symtab.c (skip_prologue_sal): Don't skip prologue for a
symtab_and_line that was set on an explicit line number in
assembler code. Do always update the recorded symtab and line if
we do skip the prologue.

* gdb.arch/amd64-break-on-asm-line.S: New file.
* gdb.arch/amd64-break-on-asm-line.exp: New file.

gdb: Remove unneeded parameter from set_breakpoint_location_function
The explicit_loc parameter in set_breakpoint_location_function is not
useful. This parameter is set from two possible fields of the
symtab_and_line used to create the breakpoint; the explicit_pc field,
and the explicit_line field.
First, the explicit_line field, this is not currently set for any
breakpoint command, so will never be true.
Next, the explicit_pc field. This can be true but will never be true
at the same time that the sal->msymbol field is also true - the
sal->msymbol is only ever set in linespec.c:minsym_found, which
doesn't allow for explicitly setting the pc.
The result of this is that if we are setting a breakpoint on an
msymbol that could turn out to be an ifunc, then we will not also have
either an explicit_pc or an explicit_line, this check can therefore be
removed.
There should be no user visible changes after this commit.
gdb/ChangeLog:
* breakpoint.c (set_breakpoint_location_function): Remove
explicit_loc parameter.
(momentary_breakpoint_from_master): Update call to
set_breakpoint_location_function.
(add_location_to_breakpoint): Likewise.

gdb/riscv: Don't use default bfd to define required features
When we initialise a gdbarch object we perform a check to try and
detect if the user is doing something silly; trying to run an RV64
binary on an RV32 target. To perform this check we compare the xlen
from the target description with the xlen specified in the headers on
the ELF being debugged.
If there is no ELF being debugged then we (currently) try to use the
bfd_arch_info from the gdbarch_info object, which will have been set
to the default architecture if no bfd is currently being debugged.
For RISC-V the default architecture is RV64.
What this means is that if a user tries to connect to an RV32 target
without specifying the BFD to debug then GDB will assume RV64. The
sanity check mentioned above will failed (xlen difference) and GDB
will throw an error. The error causes GDB to disconnect from the
remote target.
After this commit GDB no longer relies on the default bfd
architecture. If the user tries to connect without specifying the bfd
then GDB will simply make use of the xlen extracted from the target
description in order to find or create a suitable gdbarch object.
gdb/ChangeLog:
* riscv-tdep.c (riscv_features_from_gdbarch_info): Don't modify
required features based on default bfd type when no specific bfd
is present.

Re: gas/ELF: don't accumulate .type settings
git commit f2d4ba38f5 caused many failures for mips-sgi-irix targets,
and added a new test that failed for aarch64, nds32, and rl78.
The mips failures are due to BSF_OBJECT being set in many cases for
symbols by the mips .global/.globl directive. This patch removes that
code and instead sets BSF_OBJECT in a target frob_symbol function,
also moving the mips hacks in elf_frob_symbol to the new function.
Note that common symbols are handled fine in elf.c:swap_out_syms
without needing to set BSF_OBJECT, so that old code can disappear.
* config/obj-elf.c (elf_frob_symbol): Remove mips hacks.
* config/tc-mips.h (tc_frob_symbol): Define.
(mips_frob_symbol): Declare.
* config/tc-mips.c (s_mips_globl): Don't set BSF_OBJECT for irix.
(mips_frob_symbol): Fudge symbols for irix here.
* testsuite/gas/elf/type-2.e: Allow random target symbols.

Ensure GDB printf command can print convenience var strings without a target.
Without this patch, GDB printf command calls malloc on the target,
writes the convenience var content to the target,
re-reads the content from the target, and then locally printf the string.
This implies inferior calls, and does not work when there is no running
inferior, or when the inferior is a core dump.
With this patch, printf command can printf string convenience variables
without inferior function calls.
Ada string convenience variables can also be printed.

Fix breakpoints on file reloads for PIE binaries
When a binary is built using PIE, reloading the file will cause GDB to error
on restart. For example:
gdb ./a.out
(gdb) break main
(gdb) run
(gdb) file ./a.out
(gdb) continue
Will cause GDB to error with:
Continuing.
Warning:
Cannot insert breakpoint 1.
Cannot access memory at address 0x9e0
Command aborted.
This is due to the symbol offsets not being relocated after reloading the file.
Fix is to ensure solib_create_inferior_hook is called, in the same manner as
infrun.c:follow_exec().
Expand the idempotent test to cover PIE scenarios.
gdb/ChangeLog:
* symfile.c (symbol_file_command): Call solib_create_inferior_hook.

Fix TUI use of "has_break" field
The TUI uses the "has_break" in two different ways: sometimes as a
boolean, and sometimes as flags.
This patch changes the TUI to be more type-safe here, and fixes the
code. I could not find a bug that this caused, so apparently this is
just cosmetic.
This deletes some code from tui_set_disassem_content. Whenver this is
called, I believe the TUI updates the breakpoint information
afterward, so this assignment is redundant; which is good because it
is also incorrect.

Fix foreach_with_prefix regression
Fix a silly bug in commit a26c8de0ee93 ("Fix early return in
foreach_with_prefix").
That patch made foreach_with_prefix always return after the first
iteration, making ~10k tests disappear from test runs...
This fixes it, and as penance, adds a testcase that exercises all
kinds of different returns possible (ok, error, return, break,
continue). I've written it with regular "foreach", and then switched
to foreach_with_prefix and made sure we get the same results. I put
the testcase in a new gdb.testsuite/ subdir, since this is exercising
the testsuite harness bits. We can move this elsewhere if people

i386/AArch64: Remove old xml tests
Both the i386, X86_64 and AArch64 builds of gdbserver include a bunch of legacy
xml files, dat files and auto generated C files, when building for unit test.
These tests exists back from when feature target descriptions were added to
prove that the new target descriptions were identical to the original
older versions. The old files are not used for anything other than these tests.
Now that this has been proven, we are not gaining anything by keeping the
original files and tests. Should new functionality be added, it would break
the tests, unless the functionality was backported to the xml. There is no
requirement that we must match the exact xml from N releases ago. It adds
obfuscation, where as the feature target descriptions were meant to simplify
the code.
In addition, there are a bunch of xml and dat files which are completely unused.
This patch removes the selftests and the target descriptions from gdbserver.
Update the unittest to allow 0 tests (note, this failed on other targets that
never had any tests).

x86: correct "-Q" option handling
For another patch I wanted to use a sufficiently benign option (simply
to be able to specify one, which certain test case invocations require),
and I stumbled across -Q in the --help output. Before realizing that
this is x86-specific anyway, I've tried and and ran into a mysterious
testsuite failure, until I further realized that other than the help
text suggests the option requires an argument. Correct the help text,
and make the implementation actually match what the comment there has
been describing (and what the help text now says).

gas/ELF: don't accumulate .type settings
Recently a patch was submitted for a Xen Project test harness binary to
override the compiler specified @object to @func (see [1]). In a reply I
suggested we shouldn't make ourselves dependent on currently unspecified
behavior of gas here: It accumulates all requests, and then
bfd/elf.c:swap_out_syms(), in an apparently ad hoc manner, prioritizes
certain flags over others.
Make the behavior predictable: Generally the last .type is what counts.
Exceptions are directives which set multiple bits (TLS, IFUNC, and
UNIQUE): Subsequent directives requesting just the more generic bit
(i.e. FUNC following IFUNC) won't clear the more specific one. Warn
about incompatible changes, except from/to STT_NOTYPE.
Also add a new target hook, which hppa wants to use right away afaict.
In the course of adding the warning I ran into two ld testsuite
failures. I can only assume that it was a copy-and-paste mistake that
lead to the same symbol having its type set twice.

Fix early return in foreach_with_prefix
I noticed that an early return in a foreach_with_prefix block does not
cause the outer scope to return, like:
foreach_with_prefix var {"foo" "bar"} {

Teach gdb::option about string options
A following patch will make the "pipe" command use the gdb::option
framework for option processing. However, "pipe"'s only option today
is a string option, "-d DELIM", and gdb::option does not support
string options yet.
This commit adds support for string options, mapped to var_string.
For now, a string is parsed up until the first whitespace. I imagine
that we'll need to add support for quoting so that we could do:
(gdb) cmd -option 'some -string'
without gdb confusing the "-string" for an option.
This doesn't seem important for pipe, so I'm leaving it for another
day.
One thing I'm not happy with, is that the string data is managed as a
raw malloc-allocated char *, which means that we need to xfree it
manually. This is because var_string settings work that way too.
Although with var_string settings we're leaking the strings at gdb
exit, that was never really a problem. For options though, leaking is
undesirable.
I think we should tackle that for both settings and options at the
same time, so for now I'm just managing the malloced data manually.
It's a bit ugly in option_def_and_value, but at least that's hidden
from view.
For testing, this adds a new "-string" option to "maint
test-settings", and then tweaks gdb.base/options.exp to exercise it.

Make gdb::option::complete_options save processed arguments too
Currently, gdb::option::complete_options just discards any processed
option argument, because no completer needs that data.
When completing "pipe -d XXX gdbcmd XXX" however, the completer needs
to know about -d's argument (XXX), in order to know where input is
already past the gdb command and the delimiter.
In this commit, the fix for that is the factoring out of the
save_option_value_in_ctx function and calling it in complete_options.
For testing, this makes "maint show test-options-completion-result"
show the processed options too, like what the "maint test-options"
subcommands output when run. Then, of course, gdb.base/options.exp is
adjusted.
Doing this exposed a couple latent bugs, which is what the other gdb
changes in the patch are for:
- in the var_enum case, without the change, we'd end up with a null
enum argument, and print:
"-enum (null)"
- The get_ulongest change is necessary to avoid advancing PP in a
case where we end up throwing an error, e.g., when parsing "11x".
Without the change the operand pointer shown by "maint show
test-options-completion-result" would be left pointing at "x"
instead of "11x".

Fix test_gdb_complete_tab_multiple race
Running 'make check-read1 TESTS="gdb.base/options.exp"' revealed a
race in test_gdb_complete_tab_multiple. There's a gdb_test_multiple
call that expects a prompt in the middle of the regexp. That's racy
because gdb_test_multiple includes a built-in FAIL pattern for the
prompt, which may match if gdb is slow enough to produce the rest of
the output after the prompt.
Fix this in the usual way of splitting the matching in two.

Introduce the "with" command
( See original discussion and prototype here:
https://sourceware.org/ml/gdb-patches/2019-05/msg00570.html )
(gdb) help with
Temporarily set SETTING to VALUE, run COMMAND, and restore SETTING.
Usage: with SETTING [VALUE] [-- COMMAND]
Usage: w SETTING [VALUE] [-- COMMAND]
With no COMMAND, repeats the last executed command.
SETTING is any setting you can change with the "set" subcommands.
E.g.:
with language pascal -- print obj
with print elements unlimited -- print obj
As can be seen above, the "with" command is just like "set", but
instead of setting the setting permanently, it sets the setting, runs
a command and then restores the setting.
(gdb) p g_s
$1 = {a = 1, b = 2, c = 3}
(gdb) with language ada -- print g_s
$2 = (a => 1, b => 2, c => 3)
Warning: the current language does not match this frame.
(gdb) show language
The current source language is "auto; currently c".
(gdb) with print elements 100 -- with print object on -- print 1
$3 = 1
You can shorten things a bit though, as long as unambiguous. So this:
(gdb) with print elements 100 -- with print object off -- print 1
is the same as:
(gdb) w p el 100 -- w p o 0 -- p 1
Note that the patch adds a "w" alias for "with", as "w" is not
currently taken:
(gdb) w
Ambiguous command "w": watch, wh, whatis, where, while, while-stepping, winheight, ws.
Let me know if you'd prefer to reserve "w" for one of the other
commands above. IMHO, this command will end up being used frequently
enough that it deserves the "w" shorthand.
A nice feature is that this is fully integrated with TAB-completion:
(gdb) with p[TAB]
pagination print prompt python
(gdb) with print [TAB]
address max-depth static-members
array max-symbolic-offset symbol
array-indexes null-stop symbol-filename
asm-demangle object symbol-loading
demangle pascal_static-members thread-events
elements pretty type
entry-values raw union
frame-arguments repeats vtbl
inferior-events sevenbit-strings
(gdb) with print [TAB]
(gdb) with print elements unlimited -- thread apply all -[TAB]
-ascending -c -q -s
(gdb) with print elements unlimited -- print -[TAB]
-address -max-depth -repeats -vtbl
-array -null-stop -static-members
-array-indexes -object -symbol
-elements -pretty -union
The main advantage of this new command compared to command options,
like the new "print -OPT", is that this command works with any
setting, and, it works nicely when you want to override a setting
while running a user-defined command, like:
(gdb) with print pretty -- usercmd
The disadvantage is that it isn't as compact or easy to type. I think
of command options and this command as complementary. I think that
even with this new command, it makes sense to continue developing the
command options in the direction of exposing most-oft-used settings as
command options.
Inspired by Philippe's "/" command proposal, if no command is
specified, then the last command is re-invoked, under the overridden
setting:
(gdb) p g_s
$1 = {a = 1, b = 2, c = 3}
(gdb) with language ada
$2 = (a => 1, b => 2, c => 3)
Warning: the current language does not match this frame.
Note: "with" requires "--" to separate the setting from the command.
It might be possible to do without that, but, I haven't tried it yet,
and I think that this can go in without it. We can always downgrade
to making "--" optional if we manage to make it work.
On to the patch itself, the implementation of the command is simpler
than one might expect. A few details:
- I factored out a bit from pipe_command into repeat_previous
directly, because otherwise I'd need to copy&paste the same code and
same error message in the with command.
- The parse_cli_var_uinteger / parse_cli_var_zuinteger_unlimited /
do_set_command changes are necessary since we can now pass an empty
string as argument.
- do_show_command was split in two, as a FIXME comment suggests, but
for a different reason: we need to get a string version of a "set"
command's value, and we already had code for that in
do_show_command. That code is now factored out to the new
get_setshow_command_value_string function.
- There's a new "maint with" command added too:
(gdb) help maint with
Like "with", but works with "maintenance set" variables.
Usage: maintenance with SETTING [VALUE] [-- COMMAND]
With no COMMAND, repeats the last executed command.
SETTING is any setting you can change with the "maintenance set"
subcommands.
"with" and "maint with" share 99% of the implementation.
This might be useful on its own, but it's also useful for testing,
since with this, we can use the "maint set/show test-settings"
settings for exercising the "with" machinery with all the command
type variants (all enum var_types). This is done in the new
gdb/base/with.exp testcase.
The documentation bits are originally based on Philippe's docs for the
"/" command, hence the attribution in the ChangeLog.

Fix defaults of some "maint test-settings" subcommands
New tests added later for the incoming "with" command exposed a couple
invalid-default-value bugs in the "maint test-settings" commands:
- var_filename commands don't allow setting the filename to the empty
string (unlike var_optional_filename commands), yet, "maint
test-settings filename"'s control variable was not initialized, so
on startup, "maint test-settings show filename" shows an empty
string.
- "maint test-settings enum"'s control variable was not initialized,
so on startup, "maint test-settings show enum" shows an empty value
instead of a valid enum value.
Both issues are fixed by initializing the control variables.

Make "info threads" use the gdb::option framework
This makes "info threads" use the gdb::option framework to process
options. There's only one option today (-gid), and it isn't used much
frequently unless you're looking at matching MI output. Still, this
was in the neighborhood of "thread apply" so I had converted it.
The main advantage is that TAB completion now shows you the available
options, and gives you a hint to what the command accepts as operand
argument, including showing a metasyntactic variable:
(gdb) info threads [TAB]
-gid ID
(gdb) help info threads
Display currently known threads.
Usage: info threads [OPTION]... [ID]...
Options:
-gid
Show global thread IDs.
If ID is given, it is a space-separated list of IDs of threads to display.
Otherwise, all threads are displayed.

This patch fixes a bug in the AArch64 assembler where an incorrect structural load/store by element instruction would generate the wrong error message.
For example, when provided with the (incorrect) instruction
st4 {v0.16b-v3.16b}[4],[x0]
currently assembler provides the following error message
"Error: comma expected between operands at operand 2 -- `st4 {v0.16b-v3.16b}[4],[x0]'".
This was due to the assembler consuming the {v0.16b-v3.16b} as the first operand leaving
[4],[x0] as what it believed to be the second operand.
The actual error is that the first operand should be of element type and not
vector type (as provided). The new diagnostic for this error is
"Error: expected element type rather than vector type at operand 1 -- `st4 {v0.16b-v3.16b}[4],[x0]'.
Added testcases to check for the correct diagnostic message as well as checking that
variations of the structural load/store by element instruction also generate the error
when they have the same problem.

[gas][aarch64][SVE2] Fix pmull{t,b} requirement on SVE2-AES
I had mistakenly given all variants of the new SVE2 instructions
pmull{t,b} a dependency on the feature +sve2-aes.
Only the variant specifying .Q -> .D sizes should have that
restriction.
This patch fixes that mistake and updates the testsuite to have extra
tests (matching the given set of tests per line in aarch64-tbl.h that
the rest of the SVE2 tests follow).
We also add a line in the documentation of the command line to clarify
how to enable `pmull{t,b}` of this larger size. This is needed because
all other instructions gated under the `sve2-aes` architecture extension
are marked in the instruction documentation by an `HaveSVE2AES` check
while pmull{t,b} is gated under the `HaveSVE2PMULL128` check.
Regtested targeting aarch64-linux.

libctf: fix spurious error when rolling back to the first snapshot
The first ctf_snapshot called after CTF file creation yields a snapshot
handle that always yields a spurious ECTF_OVERROLLBACK error ("Attempt
to roll back past a ctf_update") on ctf_rollback(), even if ctf_update
has never been called.
The fix is to start with a ctf_snapshot value higher than the zero value
that ctf_snapshot_lu ("last update CTF snapshot value") is initialized
to.

libctf: deduplicate and sort the string table
ctf.h states:
> [...] the CTF string table does not contain any duplicated strings.
Unfortunately this is entirely untrue: libctf has before now made no
attempt whatsoever to deduplicate the string table. It computes the
string table's length on the fly as it adds new strings to the dynamic
CTF file, and ctf_update() just writes each string to the table and
notes the current write position as it traverses the dynamic CTF file's
data structures and builds the final CTF buffer. There is no global
view of the strings and no deduplication.
Fix this by erasing the ctf_dtvstrlen dead-reckoning length, and adding
a new dynhash table ctf_str_atoms that maps unique strings to a list
of references to those strings: a reference is a simple uint32_t * to
some value somewhere in the under-construction CTF buffer that needs
updating to note the string offset when the strtab is laid out.
Adding a string is now a simple matter of calling ctf_str_add_ref(),
which adds a new atom to the atoms table, if one doesn't already exist,
and adding the location of the reference to this atom to the refs list
attached to the atom: this works reliably as long as one takes care to
only call ctf_str_add_ref() once the final location of the offset is
known (so you can't call it on a temporary structure and then memcpy()
that structure into place in the CTF buffer, because the ref will still
point to the old location: ctf_update() changes accordingly).
Generating the CTF string table is a matter of calling
ctf_str_write_strtab(), which counts the length and number of elements
in the atoms table using the ctf_dynhash_iter() function we just added,
populating an array of pointers into the atoms table and sorting it into
order (to help compressors), then traversing this table and emitting it,
updating the refs to each atom as we go. The only complexity here is
arranging to keep the null string at offset zero, since a lot of code in
libctf depends on being able to leave strtab references at 0 to indicate
'no name'. Once the table is constructed and the refs updated, we know
how long it is, so we can realloc() the partial CTF buffer we allocated
earlier and can copy the table on to the end of it (and purge the refs
because they're not needed any more and have been invalidated by the
realloc() call in any case).
The net effect of all this is a reduction in uncompressed strtab sizes
of about 30% (perhaps a quarter to a half of all strings across the
Linux kernel are eliminated as duplicates). Of course, duplicated
strings are highly redundant, so the space saving after compression is
only about 20%: when the other non-strtab sections are factored in, CTF
sizes shrink by about 10%.
No change in externally-visible API or file format (other than the
reduction in pointless redundancy).

x86: drop Vec_Imm4
It is pretty wasteful to have a per-operand flag which is used in
exactly 4 cases. It can be relatively easily replaced, and by doing so
I've actually found some dead code to remove at the same time (there's
no case of ImmExt set at the same time as Vec_Imm4).

for -O2 and above though, at least for now.

x86-64: optimize certain commutative VEX-encoded insns
When they're in the 0F opcode space, swapping their source operands may
allow switching from 3-byte to 2-byte VEX prefix encoding. Note that NaN
behavior precludes us doing so for many packed and scalar floating point
insns; such an optimization would need to be done by the compiler
instead in this case, when it knows that NaN-s have undefined behavior
anyway.
While for explicitly specified AVX/AVX2 insns the optimization (for now
at least) gets done only for -O2 and -Os, it is utilized by default in
SSE2AVX mode, as there we're re-writing the programmer's specified insns
anyway.
Rather than introducing a new attribute flag, the change re-uses one
which so far was meaningful only for EVEX-encoded insns.

Adjust i386 registers on SystemTap probes' arguments (PR breakpoints/24541)
This bug has been reported on PR breakpoints/24541, but it is possible
to reproduce it easily by running:
make check-gdb TESTS=gdb.base/stap-probe.exp RUNTESTFLAGS='--target_board unix/-m32'
The underlying cause is kind of complex, and involves decisions made
by GCC and the sys/sdt.h header file about how to represent a probe
argument that lives in a register in 32-bit programs. I'll use
Andrew's example on the bug to illustrate the problem.
libstdc++ has a probe named "throw" with two arguments. On i386, the
probe is:
stapsdt 0x00000028 NT_STAPSDT (SystemTap probe descriptors)
Provider: libstdcxx
Name: throw
Location: 0x00072c96, Base: 0x00133d64, Semaphore: 0x00000000
Arguments: 4@%si 4@%di
I.e., the first argument is an unsigned 32-bit value (represented by
the "4@") that lives on %si, and the second argument is an unsigned
32-bit value that lives on %di. Note the discrepancy between the
argument size reported by the probe (32-bit) and the register size
being used to store the value (16-bit).
However, if you take a look at the disassemble of a program that uses
this probe, you will see:
00072c80 <__cxa_throw@@CXXABI_1.3>:
72c80: 57 push %edi

72ccc: 66 90 xchg %ax,%ax
72cce: 66 90 xchg %ax,%ax
Note how the program is actually using %edi, and not %di, to store the
second argument. This is the problem here.
GDB will basically read the probe argument, then read the contents of
%di, and then cast this value to uint32_t, which causes the wrong
value to be obtained. In the gdb.base/stap-probe.exp case, this makes
GDB read the wrong memory location, and not be able to display a test
string. In Andrew's example, this causes GDB to actually stop at a
"catch throw" when it should actually have *not* stopped.
After some discussion with Frank Eigler and Jakub Jelinek, it was
decided that this bug should be fixed on the client side (i.e., the
program that actually reads the probes), and this is why I'm proposing
this patch.
The idea is simple: we will have a gdbarch method, which, for now, is
only used by i386. The generic code that deals with register operands
on gdb/stap-probe.c will call this method if it exists, passing the
current parse information, the register name and its number.
The i386 method will then verify if the register size is greater or
equal than the size reported by the stap probe (the "4@" part). If it
is, we're fine. Otherwise, it will check if we're dealing with any of
the "extendable" registers (like ax, bx, si, di, sp, etc.). If we
are, it will change the register name to include the "e" prefix.
I have tested the patch here in many scenarios, and it fixes Andrew's
bug and also the regressions I mentioned before, on
gdb.base/stap-probe.exp. No regressions where found on other tests.

Fix crash when using PYTHONMALLOC=debug (PR python/24742)
This bug was originally reported against Fedora GDB:
https://bugzilla.redhat.com/show_bug.cgi?id=1723564
The problem is that GDB will crash in the following scenario:
- PYTHONMALLOC=debug or PYTHONDEVMODE=1 is set.
- The Python debuginfo is installed.
- GDB is used to debug Python.
The crash looks like this:
$ PYTHONMALLOC=debug gdb -args python3 -c pass
GNU gdb (GDB) Fedora 8.3-3.fc30

at p-4: 0x00 *** OUCH
at p-3: 0x00 *** OUCH

Because memory is corrupted at the start, the count of bytes requested
may be bogus, and checking the trailing pad bytes may segfault.
The 8 pad bytes at tail=0x706483999ad1f330 are Segmentation fault (core dumped)
It's hard to determine what happens, but after doing some
investigation and talking to Victor Stinner I found that GDB should
not use the Python memory allocation functions before the Python
interpreter is initialized (which makes sense). However, we do just
that on python/python.c:do_start_initialization:
...
progsize = strlen (progname.get ());
progname_copy = (wchar_t *) PyMem_Malloc ((progsize + 1) * sizeof (wchar_t));
...
/* Note that Py_SetProgramName expects the string it is passed to
remain alive for the duration of the program's execution, so
it is not freed after this call. */
Py_SetProgramName (progname_copy);
...
Py_Initialize ();
PyEval_InitThreads ();
Upon reading the Python 3 C API documentation, I
found (https://docs.python.org/3.5/c-api/memory.html):
To avoid memory corruption, extension writers should never try to
operate on Python objects with the functions exported by the C
library: malloc(), calloc(), realloc() and free(). This will result in
mixed calls between the C allocator and the Python memory manager with
fatal consequences, because they implement different algorithms and
operate on different heaps. However, one may safely allocate and
release memory blocks with the C library allocator for individual
purposes[...]
And Py_SetProgramName seems like a very simple call that doesn't need
a Python-allocated memory to work on. So I'm proposing this patch,
which simply replaces PyMem_Malloc by xmalloc.
Testing this is more complicated. First, the crash is completely
non-deterministic; I was able to reproduce it 10 times in a row, and
then I wasn't able to reproduce it anymore. I found that if you
completely remove your build directory and rebuild GDB from scratch,
you can reproduce it again confidently. And with my patch, I
confirmed that the bug doesn't manifest even in this situation.
No regressions found.
OK to apply?

Handle either order of name and linkage name
We discovered that the Ada support in gdb depends on the order of the
DW_AT_name and DW_AT_linkage_name attributes in the DWARF. In
particular, if they are emitted in the "wrong" order for some system
symbols, "catch exception" will not work.
This patch fixes this problem by arranging to always prefer the
linkage name if both exist. This seems to be what the full symbol
reader already does -- that is, this is another bug arising from
having two different DWARF readers.
Another possible issue here is that gdb still doesn't really preserve
mangled names properly. There's a PR open about this. However, this
seems to be somewhat involved to fix, which is why this patch
continues to work around the bigger issue.

Plugin target handling
This patch fixes failures with LTO on mingw32 targets. Since git
commit 7cf7fcc83c all possible targets (minus binary) are matched in
bfd_check_format_matches rather than lower priority targets being
excluded once a higher priority target matches. During linking that
results in the ld/plugin.c plugin_object_p function being called with
the input file xvec set to plugin_vec, which means
plugin_get_ir_dummy_bfd doesn't see the real format of the file
(pe-i386). It defaults to the output format instead, which happens to
be pei-i386, and this wrong choice persists for the dummy bfd.
pei-i386 isn't recognised as a valid linker input file.
So, omit recognizing a plugin object in bfd_check_format_matches when
some other object format matches, and make sure those other object
formats are checked first.
* format.c (bfd_check_format_matches): Don't match plugin target
if another target matches. Expand comment.

This fixes a bug in the ARm assembler where an immediate operand larger than 4 bits (0xF) could be passed to the SMC (Secure Monitor Call) instruction.
For example, this code is invalid:
smc #0x6951
The code would previously check for and encode for up to 16 bit immediate values, however
this immediate should instead be only a 4 bit value
(as documented herehttps://static.docs.arm.com/ddi0406/c/DDI0406C_C_arm_architecture_reference_manual.pdf ).
Fixed this by adding range checks in the relevant areas and also removing code that would
encode more than the first 4 bits of the immediate (code that is now redundant, as any immediate operand
larger than 0xF would error now anyway).

x86: allow VEX et al encodings in 16-bit (protected) mode
These encodings aren't valid in real and VM86 modes, but they are very
well usable in 16-bit protected mode.
A few adjustments in the disassembler tables are needed where Ev or Gv
were wrongly used. Additionally an adjustment is needed to avoid
printing "addr32" when that's already recognizable by the use of %eiz.
Furthermore the Iq operand template was wrong for XOP:0Ah encoding
insns: They're having a uniform 32-bit immediate. Drop Iq and introduce
Id instead.
Clone a few existing test cases to exercise assembler and disassembler.

RISC-V: Make objdump disassembly work right for binary files.
Without the ELF header to set info->endian, it ends up as BFD_UNKNOWN_ENDIAN
which gets printed as big-endian. But RISC-V instructions are always little
endian, so we can set endian_code correctly, and then set display_endian from
that. This is similar to how the aarch64 support works, but without the
support for constant pools, as we don't have that on RISC-V.

[gdb/testsuite] Compile varval twice, once without bad DWARF
When we run gdb.dwarf2/varval.exp with board cc-with-dwz, we run into:
...
gdb compile failed, dwz: varval: Couldn't find DIE referenced by \
DW_OP_GNU_variable_value
cc-with-tweaks.sh: dwz did not modify varval.
UNTESTED: gdb.dwarf2/varval.exp: failed to prepare
...
The problem is that varval contains some bad DWARF, which has been added
intentionally to test GDB, but that bad DWARF causes dwz to error out, which
has the consequence that the test-case remains untested with cc-with-dwz,
while the test-case contains also correct DWARF that does not occur in any
other test, and which we would really like to test with board cc-with-dwz.
Fix this by compiling varval twice, once without and once with the bad DWARF,
such that we have at least:
...

PASS: gdb.dwarf2/varval.exp: print varval2

[gdb/testsuite] Add back missing debug for index-cache.exp
The proc prepare_for_testing has "debug" as default argument for the options
parameter.
In the commit c596f180a1 "[gdb/testsuite] Compile index-cache.c with
-Wl,--build-id", by setting the options argument we've effectively dropped
"debug". This causes index-cache.exp to not contain any debug info anymore on

arm-tdep: sort mapping symbols after parsing all minimal symbols
Somebody on IRC reported a while ago that loading a big ARM program in
GDB was very slow. Their profiling pointed out that a big amount of
time was spent in
VEC_safe_insert (arm_mapping_symbol_s, *map_p, idx, &new_map_sym);
I was able to verify this as well.
ARM mapping symbols are special ELF symbols named $a, $d and $t
indicating that symbols starting at this address up to the next mapping
symbol (in terms of address) are of type "ARM code", "data" and "Thumb
code", respectively. GDB records these symbols in vectors (one for each
section) in arm-tdep.c. These vectors are sorted by symbol address, to
allow for quick lookup. The current approach is to insert new symbols
at the right position to keep the vectors sorted at all time. This is
done based on the assumption that mapping symbols come already almost
sorted from the binary, as explains this comment in
arm_record_special_symbol:
/* Assume that most mapping symbols appear in order of increasing
value. If they were randomly distributed, it would be faster to
always push here and then sort at first use. */
Well, it turns out this is not the case. The original reporter
mentioned that mapping symbols in their binaries are not nearly sorted,
and this is not my experience either (at least in the binary used in the
benchmark below). So if the values don't come nearly sorted, doing
insertions to keep the vectors sorted ends up being of the order of
number_of_mapping_symbols ^ 2.
This patch changes it just like the comment above says, to just append
to the vector in arm_record_special_symbol and sort the vector on first
use.
Benchmark
=========
I have done some benchmarks using an --enable-targets=all GDB, compiled
with -O2, running on x86-64 and parsing file
dce18d22e5c2ecb6a3a57372f4e6ef614130bc.debug from this package:
https://launchpad.net/ubuntu/+source/firefox/66.0.3+build1-0ubuntu1/+build/16608691/+files/firefox-dbg_66.0.3+build1-0ubuntu1_armhf.deb
This file is the separate debug info for libxul.so (part of firefox) for
ARM.
I have added some traces to measure the execution time of just
elf_symtab_read and ran GDB like this:
./gdb --data-directory=data-directory -nx -batch .../path/to/usr/lib/debug/.build-id/65/dce18d22e5c2ecb6a3a57372f4e6ef614130bc.debug
Since the new code sorts the vectors on first use, it would be difficult
to benchmark it as-is and be fair, since the "before" version does more
work in elf_symtab_read. So I have actually benchmarked a version of
the patch that did sort all the vectors at the end of elf_symtab_read,
so the sorting would be considered in the measured execution time.
Here's the measured execution time of elf_symtab_read, averaged on 3
runs:
insert sorted (before): 28.678s
sort after (after): 1.760s
And here's the total execution time of the command above (just one run).
The time is now mostly spent in reading DWARF.
insert sorted: 71.12s user 2.71s system 99% cpu 1:14.03 total
sort after: 46.42s user 2.60s system 99% cpu 49.147 total
I tried for fun on my Raspberry Pi 3, the run time of
elf_symtab_read goes from ~259s to ~9s, reading the same file.

MIPS/gas: Fix order of instructions in LI macro expansion
When MTHC1 instruction is paired with MTC1 to write a value to a
64-bit FPR, the MTC1 must be executed first, because the semantic
definition of MTC1 is not aware that software will be using an MTHC1
to complete the operation, and sets the upper half of the 64-bit FPR
to an UNPREDICTABLE value[1].
Fix the order of MTHC1 and MTC1 instructions in LI macro expansion.
Modify the expansions to exploit moves from $zero directly by-passing
the use of $AT, where ever possible.

( https://bugs.llvm.org/show_bug.cgi?id=9995 ) causing this problem.
Fix this by regenerating using clang 5.0.1.
Tested on x86_64-linux.

Remove union tui_which_element
This removes union tui_which_element, instead moving the content
directly into tui_source_window_base. This allows for the deletion of

which members are in use by which subtype.

Use bool for is_exec_point
This changes tui_source_element::is_exec_point to be a bool. I looked
at also changing "has_break", but it turns out that this field is used
inconsistently (sometimes as flags and sometimes as a bool), and so
needs more invesstigation before it can be changed.

Remove some TUI static allocations
The TUI statically allocates the "execution_info" for the source and
disassembly windows. However, there's no deep reason to do this, and
this approach makes it harder to allow multiple such windows.

allocate these windows as needed. This required pushing some code
into the tui_gen_win_info destructor, but that seems like a good idea
anyhow.

Introduce tui_gen_win_info::reset method
This introduces the tui_gen_win_info::reset method and changes various
places to use it. This led to the realization that the can_highlight
member only needs to be set during construction, so this patch makes
that change as well. Finally, init_and_make_win is drastically
simplified.

Remove an unneeded NULL check
show_source_or_disasm_and_command will either create or reset the

Remove struct tui_source_info
The tui_source_info struct is used as a member of the "detail" union
in tui_win_info, and this member of the union is only used by source
and disassembly windows. This patch removes tui_source_info and moves
its members directly to tui_source_window_base. This simplifies the
code by removing a layer of references from many places. In a few
spots, a new cast was needed, but most of these will be removed by the
end of the series.

x86: correct / adjust debug printing
For quite some time we've been using combinations of bits for
specifying various registers in operands and templates. I think it was
Alan who had indicated that likely the debug printing would need
adjustment as a result. Here we go.
Accumulator handling for GPRs gets changed to match that for FPU regs.
For this to work, OPERAND_TYPE_ACC{32,64} get repurposed, with their
original uses replaced by direct checks of the two bits of interest,
which is cheaper than operand_type_equal() invocations.
For SIMD registers nothing similar appears to be needed, as respective
operands get stripped from the (copy of the) template before pt() is
reached.
The type change on pi() is to silence a compiler diagnostic. Arguably
its other parameter could also be const-qualified.

x86: drop dqa_mode
I assume this mode was needed when EVEX.W handling wasn't really correct
yet for other than 64-bit mode. It's clearly not needed anymore. Its
elimination also allows dropping the EVEX.W split of VCVT{,U}SI2SS. (For
the record, the dropped mode would have been wrong if used in any table

everything else into OP_I(), and drop no longer needed local

x86: fix (dis)assembly of certain SSE2 insns in 16-bit mode
MOVNTI was wrongly assembled with a 66h prefix. Add IgnoreSize to
address this. It and the scalar to/from integer conversion insns also
were also wrongly using Ev / Gv, leading to 16-bit register names being
printed when 32-bit ones were meant.
Clone the 32-bit SSE2 test to cover both assembler and disassembler.

When running gdb.trace/{entry-values.exp,unavailable-dwarf-piece.exp} with
board cc-with-dwz, we run into two failures related to the DW_AT_decl_file
attribute:
- The encoding DW_FOR_sdata is used for DW_AT_decl_file, while the attribute
is required to have a an "unsigned integer constant" value.
- The DW_AT_decl_file attributes refer to a file with index one, while there's
no such file.
Fix this by using DW_FOR_udata and the value 0, meaning "no file specified".

PR24704, Internal error building skiboot for powerpc64-linux-gnu
While the skiboot linker script bears some culpability in this PR,
it's also true that the GOT indirect to GOT relative optimisation for
16-bit offsets isn't safe. At least, it isn't safe to remove the GOT
entry based on distance between the GOT pointer and symbol calculated
from the preliminary layout. So this patch removes that optimisation,
and reduces the range allowed for 32-bit and 34-bit offsets.

[gdb] Fix s390x -m31 build
When building gdb on s390x with -m31, we run into this Wformat
warning (which Werror turns into an error):
...
gdb/dwarf2read.c: In function \
'void create_addrmap_from_aranges(dwarf2_per_objfile*, \
dwarf2_section_info*)':
gdb/dwarf2read.c:3277:22: error: format '%zu' expects argument of type \
'size_t', but argument 3 has type 'int' [-Werror=format=]
warning (_("Section .debug_aranges in %s entry at offset %zu "
...
The Wformat warning is triggered in this statement:
...
warning (_("Section .debug_aranges in %s entry at offset %zu "
"length %s exceeds section length %s, "
"ignoring .debug_aranges."),
objfile_name (objfile), entry_addr - section->buffer,
plongest (bytes_read + entry_length),
pulongest (section->size));
...
where 'entry_addr - section->buffer' is of type ptrdiff_t and '%zu' prints an
unsigned with the same size as size_t/ssize_t.
On s390x with -m31, we have:
- size_t : unsigned long int (32-bit)
- ptrdiff_t: int (32-bit)
Wformat warns against this because even though long int and int have the same
size, the types are not compatible.
[ The Wformat warning is to similar to what we would get for x86_64 -m32
(where long and int are also the same size) and:
...
int i;
printf ("%ld", i);
... ]
Fix this by using '%s' and plongest instead of '%zu' to print ptrdiff_t.

libctf: fix ctf_open endianness problems with raw CTF files
ctf_open (or, rather, ctf_fdopen, which underlies it) has several
endianness problems, even though it was written after the
endian-swapping code was implemented, so should have been endian-aware.
Even though the comment right above the relevant check says that it wil
check for CTF magic in any endianness, it only checks in the native
endianness, so opening raw LE CTF files on BE, or vice-versa, will fail.
It also checks the CTF version by hand, without ever endianness-swapping
the header, so that too will fail, and is entirely redundant because
ctf_simple_open does the job properly in any case. We have a similar
problem in the next if block, which checks for raw CTF archives: we are
checking in the native endianness while we should be doing a le64toh()
on it to check in little-endian form only: so opening CTF archives
created on the local machine will fail if the local machine is
big-endian.
Adding insult to injury, if ctf_simple_open then fails, we go on and try
to turn it into a single-element CTF archive regardless, throwing the
error away. Since this involves dereferencing null pointers it is not
likely to work very well.
libctf/
* ctf-open-bfd.c: Add swap.h and ctf-endian.h.
(ctf_fdopen): Check for endian-swapped raw CTF magic, and
little-endian CTF archive magic. Do not check the CTF version:
ctf_simple_open does that in endian-safe ways. Do not dereference
null pointers on open failure.

libctf: endianness fixes
Testing of the first code to generate CTF_K_SLICEs on big-endian
revealed a bunch of new problems in this area. Most importantly, the
trick we did earlier to avoid wasting two bytes on padding in the
ctf_slice_t is best avoided: because it leads to the whole file after
that point no longer being naturally aligned, all multibyte accesses
from then on must use memmove() to avoid unaligned access on platforms
where that is fatal. In future, this is planned, but for now we are
still doing direct access in many places, so we must revert to making
ctf_slice_t properly aligned for storage in an array.
Rather than wasting bytes on padding, we boost the size of cts_offset
and cts_bits. This is still a waste of space (we cannot have offsets or
bits in bitfields > 256) but it cannot be avoided for now, and slices
are not so common that this will be a serious problem.
A possibly-worse endianness problem fixed at the same time involves
a codepath used only for foreign-endian, uncompressed CTF files, where
we were not copying the actual CTF data into the buffer, leading to
libctf reading only zeroes (or, possibly, uninitialized garbage).
Finally, when we read in a CTF file, we copy the header and work from
the copy. We were flipping the endianness of the header copy, and of
the body of the file buffer, but not of the header in the file buffer
itself: so if we write the file back out again we end up with an
unreadable frankenfile with header and body of different endiannesses.
Fix by flipping both copies of the header.
include/
* ctf.h (ctf_slice_t): Make cts_offset and cts_bits unsigned
short, so following structures are properly aligned.
libctf/
* ctf-open.c (get_vbytes_common): Return the new slice size.
(ctf_bufopen): Flip the endianness of the CTF-section header copy.
Remember to copy in the CTF data when opening an uncompressed
foreign-endian CTF file. Prune useless variable manipulation.

libctf: unidentified type kinds on open are a sign of file corruption
If we see a CTF type with a kind we do not recognize in its ctt_info
during opening, we cannot skip it and continue opening the file: if the
type kind is unknown, we do not know how long its vlen is, and we cannot
have skipped past it: so if we continue reading we will almost certainly
read in part of the vlen as if it were a new ctf_type_t.
Avoid this trouble by considering unknown type kinds to be a reason to
return ECTF_CORRUPT, just like everything else that reads in type kinds
does.
libctf/
* ctf-open.c (ctf_types): Fail when unidentified type kinds are
seen.

libctf: dump header offsets into the debugging output
This is an essential first piece of info needed to debug both libctf
writing and reading problems, and we weren't recording it anywhere!
(This is a short-term fix: fairly soon, we will record all of this in a
form that outlives ctf_bufopen, and then ctf_dump() will be able to dump
it like it can everything else.)
libctf/
* ctf-open.c (ctf_bufopen): Dump header offsets into the debugging
output.

libctf: drop mmap()-based CTF data allocator
This allocator has the ostensible benefit that it lets us mprotect() the
memory used for CTF storage: but in exchange for this it adds
considerable complexity, since we have to track allocation sizes
ourselves for use at freeing time, note whether the data we are storing
was ctf_data_alloc()ed or not so we know if we can safely mprotect()
it... and while the mprotect()ing has found few bugs, it *has* been the
cause of more than one due to errors in all this tracking leading to us
mprotect()ing bits of the heap and stuff like that.
We are about to start composing CTF buffers from pieces so that we can
do usage-based optimizations on the strtab. This means we need
realloc(), which needs nonportable mremap() and *more* tracking of the
*original* allocation size, and the complexity and bureaucracy of all of
this is just too high for its negligible benefits.
Drop the whole thing and just use malloc() like everyone else. It knows
better than we do when it is safe to use mmap() under the covers,
anyway.
While we're at it, don't leak the entire buffer if ctf_compress_write()
fails to compress it.

PR24689, string table corruption
The testcase in the PR had a e_shstrndx section of type SHT_GROUP.
hdr->contents were initialized by setup_group rather than being read
from the file, thus last byte was not zero and string dereference ran
off the end of the buffer.

* elfcode.h (elf_object_p): Check type of e_shstrndx section.

[gdbserver] Fix s390x -m31 gdbserver build
When building gdb on s390x with -m31, we run into this error:
...
gdb/gdbserver/linux-s390-ipa.c: \
In function 'const target_desc* get_ipa_tdesc(int)':
gdb/gdbserver/linux-s390-ipa.c:371:18: error: 's390_te_ft_collect_regmap' \
was not declared in this scope
SET_REGMAP(s390_te_ft_collect_regmap, 0);
The offending line is part of this code snippet:
...
case S390_TDESC_GS:
SET_REGMAP(s390_te_ft_collect_regmap, 0);
return tdesc_s390_gs_linux64;
...
introduced in commit ce29f8439f "S390: Make IPA recognize tdescs with guarded
storage".
The snippet is part of an #ifdef __s390x__ construct, in the false branch, and
in the true branch we find a snippet introduced by the same commit:
...
case S390_TDESC_GS:
SET_REGMAP(s390x_te_ft_collect_regmap, 0);
return tdesc_s390x_gs_linux64;
...
which is paired with a comment update for s390x_te_ft_collect_regmap:
...
-/* Used for s390x-te-linux64, s390x-tevx-linux64. */
+/* Used for s390x-te-linux64, s390x-tevx-linux64, and
+ s390x-gs-linux64. */
static const int s390x_te_ft_collect_regmap[] = {
...
A similar comment update is added in the same commit for
s390_te_linux64_ft_collect_regmap:
...
-/* Used for s390-te-linux64, s390-tevx-linux64. */
+/* Used for s390-te-linux64, s390-tevx-linux64, and s390-gs-linux64. */
static const int s390_te_linux64_ft_collect_regmap[] = {
...
but not paired with any update.
Fix the build breaker by making the offending SET_REGMAP use the regmap
indicated by the comment.
...
- SET_REGMAP(s390_te_ft_collect_regmap, 0);
+ SET_REGMAP(s390_te_linux64_ft_collect_regmap, 0);
...
Build on s390x-linux with -m31.
gdb/gdbserver/ChangeLog:
2019-06-20 Tom de Vries <tdevries@suse.de>
* linux-s390-ipa.c (get_ipa_tdesc)[!__s390x__]: Use

Fix crash when setting breakpoint condition
gdb could crash when setting a breakpoint condition on a breakpoint
when using the Ada language. The problem occurred because the
ada_evaluate_subexp would try to evaluate the array to compute its
attributes, but evaluating can't really be done at this time.
This patch fixes the problem by arranging not to try to evaluate in
EVAL_AVOID_SIDE_EFFECTS mode when computing an attribute.
Tested on x86-64 Fedora 29. Because this is Ada-specific, and because
Joel approved it internally, I am checking it in.

Instantiate a single source highlighter
It occurred to me that there's no reason to make a new source
highlighter each time gdb needs to highlight some source code.
Instead, a single one can be created and then simply reused each time.
This patch implements this idea. Tested on x86-64 Fedora 29.

* source-cache.c (highlighter): New global.

PowerPC64 notoc calls
Calls from functions that don't have a valid toc pointer in r2 (these
calls are marked with _NOTOC relocs) to functions that require r2
valid must go via the callee global entry point. This patch corrects
the condition the linker was using to detect functions that require r2
to be valid. Values of both zero and one in st_other local entry bits
mean a function doesn't care about r2.
* elf64-ppc.c (ppc64_elf_inline_plt): Correct st_other test for
functions that require r2 valid to use local entry.
(ppc64_elf_size_stubs, ppc64_elf_relocate_section): Likewise.

gdb: Remove use of deprecated_interactive_hook
The deprecated_interactive_hook is not used within GDB. It is used in
gdbtk, however this patch removes that use:
https://sourceware.org/ml/insight/2019-q2/msg00001.html
So I think there is no longer a reason to keep this hook around.
This patch removes it. There should be no user visible changes after
this commit.
gdb/ChangeLog:
* defs.h (deprecated_interactive_hook): Delete declaration.

[gdb/testsuite] Use -fuse-ld=gold in fission.exp
The target board fission.exp requires the gold linker (because it supports
--gdb-index).
When running the target board on a system where the default linker is not
gold, most tests will fail to compile.
Fix this by adding "-fuse-ld=gold" ( supported in gcc since version 4.8).

[gdb] Fix abstract_to_concrete type
The test-case varval.exp fails here:
...
FAIL: gdb.dwarf2/varval.exp: print varval2
...
with boards readnow/cc-with-gdb-index/cc-with-debug-names, as well as if gdb
is build with -fsanitize=address -lasan.
The problem is that the abstract_to_concrete map in which we track the
association of abstract to concrete DIEs (for DW_OP_GNU_variable_value
support) has type std::unordered_map<die_info_ptr, std::vector<die_info_ptr>>,
and the die_info_ptrs that we register in the map may be invalid by the time
that we start to lookup DIEs in the map.
Fix this by using the sect_offset instead to identify the DIEs in the map.
Build and tested on x86_64-linux.

doc: fix false claim about second argument to gdb
Section "Invoking GDB" of the manual states that if you try to launch
gdb with:
gdb program 1234
it will try to attach to the process with id 1234, unless there is a
file named 1234 in the current working directory, in which case it will
try to open that file as a core. In fact, when the second argument
starts with a digit, GDB tries to attach to process 1234 first, before
trying to open file 1234 as a core. So that last remark is not true and
therefore this patch removes it.
The same remark is present in the man page, so it is removed there too.
Section "Choosing Files" correctly states:
If the second argument begins with a decimal digit, GDB will first
attempt to attach to it as a process, and if that fails, attempt to
open it as a corefile.
so it is unchanged.
Finally, the man page has an additional detail compared to section
"Invoking GDB", regarding the use of the -p switch, so I added the same
detail to the "Invoking GDB" section.
gdb/doc/ChangeLog:
* gdb.texinfo (Invoking GDB): Remove sentence about how GDB
deals with a file that has the same name as the specified pid to
attach to. Add example using -p option.
(gdb man): Remove same sentence as in previous item.

==3997==ABORTING
...
The direct cause is that child_path gets called with parent == "", so this
test:
...
if (IS_DIR_SEPARATOR (parent[parent_len - 1]))
...
accesses parent[-1].
[ There is an open discussion (1) about whether an empty sysroot should indeed
be represented internally as "". But this patch focuses on fixing the
heap-buffer-overflow without any redesign. ]
Fix this by guarding the test with 'parent_len > 0'.
Note that the fix makes child_path behave the same for:
- parent == "/" && child == "/foo" (returns "foo")
- parent == "" and child == "/foo" (returns "foo").
Build and reg-tested on x86_64-linux.

I found a few spots that directly cast a tui_win_info to a

Write index for dwz -m file
PR 24445 ("dwz multifile index not written to index cache") exposed the
fact that we are not doing things right when we generate an index for an
object file that has is linked to a dwz file. The same happens whether
the index is generated with the intent of populating the index cache or
using the save gdb-index command.
The problem can be observed when running these tests with the
cc-with-dwz-m board:
FAIL: gdb.base/index-cache.exp: test_cache_enabled_hit: check index-cache stats
FAIL: gdb.dwarf2/gdb-index.exp: index used
FAIL: gdb.dwarf2/gdb-index.exp: index used after symbol reloading
When generating the index for such file and inspecting the CU list of the
resulting index (with readelf --debug-dump=gdb_index), we can see something
like:
CU table:
[ 0] 0x0 - 0xb9
[ 1] 0x0 - 0x44
This is supposed to be a sorted list of the ranges of all CUs in the
file this index represents, so already having some overlap is a red
flag. It turns out that we save the ranges of CUs coming from both the
main file and the dwz file in the same index.
After digging a little bit, it became quite obvious that the index in
the main file should only list the CUs present in the main file, and a
separate index should be generated for the dwz file, listing the CUs
present in that file.
First, that's what happens if you run dwz on a file that already has a
GDB index embedded. Second, dwarf2read.c has code to read an index from
a dwz file. The index in the dwz file is actually required to be
present, if the main file has an index.
So this patch changes write_psymtabs_to_index to generate an index for
the dwz file, if present. That index only contains a CU list, just like
what the dwz tool does when processing a file that already contains an
index.
Some notes about the implementation:
- The file management (creating a temp file, make sure it's
close/removed on error - in the right order) is a bit heavy in
write_psymtabs_to_index, and I needed to add a third file. I factored
this pattern in a separate class, index_wip_file.
- It became a bit tedious to keep the call to assert_file_size in
write_psymtabs_to_index, write_gdbindex would have had to return two
sizes. Instead, I moved the calls to assert_file_size where the file
is written. The downside is that we lose the filename at this point,
but it was only used for the very improbable case of ftell failing, so
I think it's not a problem.
- The actual writing of the index file is factored out to
write_gdbindex_1, so it can be re-used for both index files.
- While the "save gdb-index" command will now write two .gdb-index
files, this patch does not update the gdb-add-index.sh script, this
will come in a later patch.

gdb/testsuite: Improve detection of bug gdb/24541
In bug gdb/24686 a testsuite failure was reported, this failure was
actually just another instance of bug gdb/24541, however, due to the

Make gdb.base/index-cache.exp work with readnow board (PR 24669)
The gdb.base/index-cache.exp test fails with the readnow board:
$ make check TESTS="gdb.base/index-cache.exp" RUNTESTFLAGS="--target_board=readnow"
FAIL: gdb.base/index-cache.exp: test_cache_enabled_miss: at least one file was created
FAIL: gdb.base/index-cache.exp: test_cache_enabled_miss: expected file is there
FAIL: gdb.base/index-cache.exp: test_cache_enabled_miss: check index-cache stats
FAIL: gdb.base/index-cache.exp: test_cache_enabled_hit: check index-cache stats
The problem is similar to what was fixed in
5a56d6a65f84 ("[gdb/testsuite] Fix index-cache.exp with cc-with-{gdb-index,debug-names}")
In that commit, gdb.base/index-cache.exp was modified to account for the
fact that the index cache is not used when the binary already has an
embedded index.
The same situation happens when GDB is started with the -readnow flag:
it bypasses indices and partial symbols. So this patch updates the test
to also expect the index cache not to be used if -readnow is present in
$GDBFLAGS,

gdb/fortran: Show the type for non allocated / associated types
Show the type of not-allocated and/or not-associated types. For array
types and pointer to array types we are going to print the number of
ranks.
Consider this Fortran program:
program test
integer, allocatable :: vla (:)
logical l
allocate (vla(5:12))
l = allocated (vla)
end program test
And this GDB session with current HEAD:
(gdb) start
...
2 integer, allocatable :: vla (:)
(gdb) n
4 allocate (vla(5:12))
(gdb) ptype vla
type = <not allocated>
(gdb) p vla
$1 = <not allocated>
(gdb)
And the same session with this patch applied:
(gdb) start
...
2 integer, allocatable :: vla (:)
(gdb) n
4 allocate (vla(5:12))
(gdb) ptype vla
type = integer(kind=4), allocatable (:)
(gdb) p vla
$1 = <not allocated>
(gdb)
The type of 'vla' is now printed correctly, while the value itself
still shows as '<not allocated>'. How GDB prints the type of
associated pointers has changed in a similar way.

* f-typeprint.c (f_print_type): Don't return early for not
associated or not allocated types.

gdb/mi: New commands to catch C++ exceptions
Adds some MI commands to catch C++ exceptions. The new commands are
-catch-throw, -catch-rethrow, and -catch-catch, these all correspond
to the CLI commands 'catch throw', 'catch rethrow', and 'catch catch'.
Each MI command takes two optional arguments, '-t' has the effect of
calling 'tcatch' instead of 'catch', for example:
(gdb)
-catch-throw -t
Is the same as:
(gdb) tcatch throw
There is also a '-r REGEXP' argument that can supply a regexp to match
against the exception type, so:
(gdb)
-catch-catch -r PATTERN
Is the same as:
(gdb) catch catch PATTERN
The change in print_mention_exception_catchpoint might seem a little
strange; changing the output from using ui_out::field_int and
ui_out::text to using ui_out::message.
The print_mention_exception_catchpoint is used as the 'print_mention'
method for the exception catchpoint breakpoint object. Most of the
other 'print_mention' methods (see breakpoint.c) use either
printf_filtered, of ui_out::message. Using field_int was causing an
unexpected field to be added to the MI output. Here's the output
without the change in print_mention_exception_catchpoint:
(gdb)
-catch-throw
^done,bkptno="1",bkpt={number="1",type="breakpoint",disp="keep",
enabled="y",addr="0x00000000004006c0",
what="exception throw",catch-type="throw",
thread-groups=["i1"],times="0"}
Notice the breakpoint number appears in both the 'bkptno' field, and
the 'number' field within the 'bkpt' tuple. Here's the output with
the change in print_mention_exception_catchpoint:
(gdb)
-catch-throw
^done,bkpt={number="1",type="breakpoint",disp="keep",
enabled="y",addr="0x00000000004006c0",

gdb: Don't allow annotations to influence what else GDB prints
The annotations should be additional information printed by GDB to be
consumed by users (GUIs), but GDB shouldn't reduce what it prints
based on whether annotations are on or not. However, this is what
happens for annotate_source_line.
This commit makes annotate_source_line a void function that simply
outputs the annotation information, GDB will then print the contents
of the source line to the terminal in the normal way.
Some tests needed to be updated after this commit.

gdb: Remove an update of current_source_line and current_source_symtab
While reviewing some of the annotation code I noticed that
identify_source_line (in source.c) sets current_source_line,
current_source_symtab, and also calls clear_lines_listed_range. This
seems a little strange, identify_source_line is really a wrapper
around annotate_source, and is only called when annotation_level is
greater than 0 (so annotations are turned on).
It seems weird (to me) that when annotations are on we update GDB's
idea of the "current" line/symtab, but when they are off we don't,
given that annotations are really about communicating GDB's state to a
user (GUI) and surely shouldn't be changing GDB's behaviour.
This commit removes from identify_source_line all of the setting of
current line/symtab and the call to clear_lines_listed_range, after
doing this GDB still passes all tests, so I don't believe these lines
were actually required.
With this code removed identify_source_line is only a wrapper around
annotate_source, so I moved identify_source_line to annotate.c and
renamed it to annotate_source_line.

Move gnulib to top level
This patch moves the gdb/gnulib subdirectory to the top level.
It adjusts the top-level build system to build gnulib when necessary,
and changes gdb to use this. However, gdbserver still builds its own
copy of gnulib, just from the new source location.
A small hack was needed to ensure that gnulib is only built when gdb
is enabled. The Makefile only provides an ordering -- the directory
must be mentioned in configdirs to actually be compiled at all.
Most of the patch is just a "git mv" of gnulib, though a few minor
path adjustments were needed in some files there.
Tested by the buildbot.

Only compute realpath when basenames_may_differ is set
A user noted that, when sources are symlinked, gdb annotations will
print the real path, rather than the name of the symlink.
It seems to me that it is better to print the name of the file that
was actually used in the build, unless there is some reason not to.
This patch implements this, with the caveat that it will not work when
basenames-may-differ is enabled. The way this mode is currently
implemented, returning the symbolic (not real) path is not possible.
While I think it would be good to redo the source file name cache and
perhaps integrate it with class source_cache, I haven't done so here.

Allow re-assigning to convenience variables
In Ada mode, re-assigning an array of a different size to a
convenience variable will cause an error:
(gdb) set lang ada
(gdb) set $v := "abc"
(gdb) set $v := "abcd"
cannot assign arrays of different length
However, this does not really make sense -- instead, it should always
be possible to overwrite a convenience variable.

Fix gdb.ada/vla.exp
PR ada/24539 concerns a test failure in gdb.ada/vla.exp.
The problem here is that different versions of Gnat emit the

failing actually being the correct one.
Joel pointed out that this can be fixed by simply adding the
No_Component_Reordering pragma to the type in question, which is what

Fix gdb build with -std=gnu++11
The options framework series broken the build with gcc 4.8, or any
other compiler were we end up forcing -std=gnu++11, causing errors
like these:
../../binutils-gdb/gdb/compile/compile.c: In function gdb::option::option_def_group make_compile_options_def_group(compile_options*):
../../binutils-gdb/gdb/compile/compile.c:266:44: error: could not convert (const gdb::option::option_def*)(& compile_command_option_defs) from const gdb::option::option_def* to gdb::array_view<const gdb::option::option_def>

^
CXX copying.o
../../binutils-gdb/gdb/compile/compile.c:267:1: error: control reaches end of non-void function [-Werror=return-type]
}

This is a C++11 vs C++14 difference -- C++14 relaxed the rules for

Delete parse_flags/parse_flags_qcs
Now that "thread/frame apply" have been converted to the gdb::option
framework, these functions are no longer used.
For a while, I thought about keeping the unit tests, by making a local
version of parse_flags_qcs in the unit tests file. But all that would
really test that is used by GDB itself, is the validate_flags_qcs
function. So in the end, I went through all the unit tests, and
converted any that wasn't already covered to gdb.base/options.exp

Make "thread apply" use the gdb::option framework
Similarly to the "frame apply" patch, this makes the "thread apply"
family of commands -- "thread apply TID", "thread apply all" and
"taas" use the gdb::option framework for '-'-style options.
No new options are added, but there are some user-visible changes:
- Can now abbreviate and complete "-ascending"
- We now have a completer for "thread apply" commands
Can now complete options ("thread apply all -[TAB]"), and also,
'thread apply all COMMAND[TAB]' now does what you'd expect, by
making use of the new complete_command routine.
- "help" output tweaked with auto-generated option descriptions:
~~~
Usage: thread apply all [OPTION]... COMMAND
Prints per-inferior thread number and target system's thread id
followed by COMMAND output.
By default, an error raised during the execution of COMMAND
aborts "thread apply".
Options:
-ascending
Call COMMAND for all threads in ascending order.
The default is descending order.
-q
Disables printing the thread information.
-c
Print any error raised by COMMAND and continue.
-s
Silently ignore any errors or empty output produced by COMMAND.
~~~

"thread apply 1 -- -" vs "frame apply level 0 -- -"
With the following patch, we'll be able to explicitly tell "thread
apply" where options end, using the "--" delimiter. A test added by
that patch caught a pre-existing inconsistency:
(gdb) thread apply 1 -- -
Invalid thread ID: -
(gdb) frame apply level 0 -- -
#0 main () at threads.c:55
Cannot enable the TUI when output is not a terminal
Above, "thread apply" did not try to run the command, while "frame
apply level" did. ("-" is a valid TUI command.)
That "-" is past "--", so it should have not been confused with an
invalid TID, in the "thread apply" case.
That error actually doesn't come from the TID parser, but instead from
thread_apply_command directly.
So that error/check needs tweaking. The next question is what to
tweak it to.
"-" is actually a valid TUI command:
(gdb) help -
Scroll window backward.
Usage: - [WIN] [N]
(gdb) frame apply level 0 -- -
#0 main () at threads.c:55
Cannot enable the TUI when output is not a terminal
While I don't imagine it being useful to use that "-" command with
"thread apply" or "frame apply level", the fact is that you can use it
with "frame apply level", but not with "thread apply". And since it's
an actual command, pedantically it seems right to allow it.
That's what this commit does.
Note: simply removing the "isalpha" check regresses
gdb.multi/tids.exp -- see related commit 3f5b7598805c.

Make "frame apply" support -OPT options
This adds support for '-'-style options to the "frame apply" family of
commands -- "frame apply COUNT", "frame apply level", "frame apply
all", "faas" and "tfaas".
The -q/-c/-s flags were already supported, -past-main/-past-entry is
new:
~~~
(gdb) help frame apply all
Apply a command to all frames.
Usage: frame apply all [OPTION]... COMMAND
Prints the frame location information followed by COMMAND output.
By default, an error raised during the execution of COMMAND
aborts "frame apply".
Options:
-q
Disables printing the frame location information.
-c
Print any error raised by COMMAND and continue.
-s
Silently ignore any errors or empty output produced by COMMAND.
-past-main [on|off]
Set whether backtraces should continue past "main".
Normally the caller of "main" is not of interest, so GDB will terminate
the backtrace at "main". Set this if you need to see the rest
of the stack trace.
-past-entry [on|off]
Set whether backtraces should continue past the entry point of a program.
Normally there are no callers beyond the entry point of a program, so GDB
will terminate the backtrace there. Set this if you need to see
the rest of the stack trace.
~~~
TAB completion of options is now supported. Also, TAB completion of
COMMAND in "frame apply all COMMAND" does the right thing now, making
use of complete_command, added by the previous patch. E.g.:
(gdb) thread apply all -ascending frame apply all -past-main print -[TAB]
-address -elements -pretty -symbol
-array -null-stop -repeats -union
-array-indexes -object -static-members -vtbl
(gdb) thread apply all -ascending frame apply all -past-main print glo[TAB]
global1 global2
The change to tfaas_command is necessary because otherwise you get
this:
(gdb) tfaas --
Unrecognized option at: frame apply all -s --
That's because the above is equivalent to:
(gdb) thread apply all -s frame apply all -s --
and the "--" instructs "thread apply" to consider everything up to
"--" as its command options. And from that view, "frame" is an
invalid option.
The change makes tfaas be equivalent to:
(gdb) thread apply all -s -- frame apply all -s --

Introduce complete_nested_command_line
This adds a completion helper routine that makes it possible for a
command that takes another command as argument, such as "frame apply
all COMMAND" as "thread apply all COMMAND", to complete on COMMAND,
and have the completion machinery recurse and complete COMMAND as if
you tried to complete "(gdb) COMMAND". I.e., we'll be able to
complete like this, for example:
(gdb) thread apply all -[TAB]
-c -ascending -q -s
(gdb) thread apply all -ascending frame apply all -[TAB]
-c -limit -past-entry -past-main -q -s
(gdb) thread apply all -ascending frame apply all -past-main print -[TAB]
-address -elements -pretty -symbol
-array -null-stop -repeats -union
-array-indexes -object -static-members -vtbl
(gdb) thread apply all -ascending frame apply all -past-main print glo[TAB]
global1 global2
Above, the completer function understands that "thread apply all" is a
command, and then parses "-ascending" successfully and understand that
the rest of the string is "thread apply all"'s operand. And then, the
process repeats for the "frame apply" command, and on and on.

"backtrace full/no-filters/hide" completer
"backtrace"'s completer now completes on command options:

But it doesn't know how to complete on qualifiers:

Make "backtrace" support -OPT options
This adds support for comand options to the "backtrace" command. We'll get:
(gdb) bt -
-entry-values -hide -past-main
-frame-arguments -no-filters -raw-frame-arguments
-full -past-entry
~~~~
(gdb) help backtrace
Print backtrace of all stack frames, or innermost COUNT frames.
Usage: backtrace [OPTION]... [QUALIFIER]... [COUNT | -COUNT]
Options:
-entry-values no|only|preferred|if-needed|both|compact|default
Set printing of function arguments at function entry
GDB can sometimes determine the values of function arguments at entry,
in addition to their current values. This option tells GDB whether
to print the current value, the value at entry (marked as val@entry),
or both. Note that one or both of these values may be <optimized out>.
-frame-arguments all|scalars|none
Set printing of non-scalar frame arguments
-raw-frame-arguments [on|off]
Set whether to print frame arguments in raw form.
If set, frame arguments are printed in raw form, bypassing any
pretty-printers for that value.
-past-main [on|off]
Set whether backtraces should continue past "main".
Normally the caller of "main" is not of interest, so GDB will terminate
the backtrace at "main". Set this if you need to see the rest
of the stack trace.
-past-entry [on|off]
Set whether backtraces should continue past the entry point of a program.
Normally there are no callers beyond the entry point of a program, so GDB
will terminate the backtrace there. Set this if you need to see
the rest of the stack trace.
-full
Print values of local variables.
-no-filters
Prohibit frame filters from executing on a backtrace.
-hide
Causes Python frame filter elided frames to not be printed.
For backward compatibility, the following qualifiers are supported:
full - same as -full option.
no-filters - same as -no-filters option.
hide - same as -hide.
With a negative COUNT, print outermost -COUNT frames.
~~~~
Implementation wise, this:
- Moves relevant options/settings globals to structures.
- Tweaks a number of functions to pass down references to such structures.
- Adds option_def structures describing the options/settings.
- Makes backtrace_command parse the options, with gdb::option::process_options.
- Tweaks "backtrace"'s help to describe the new options.
- Adds testcases.
Note that backtrace is a PROCESS_OPTIONS_UNKNOWN_IS_OPERAND command,
because of the "-COUNT" argument.
The COUNT/-COUNT argument is currently parsed as an expression. I
considered whether it would be prudent here to require "--", but
concluded that the risk of causing a significant breakage here is much
lower compared to "print", since printing the expression is not the
whole point of the "backtrace" command. Seems OK to me to require
typing "backtrace -past-main -- -p" if the user truly wants to refer
to the negative of a backtrace count stored in an inferior variable
called "p".

"set print raw frame-arguments" -> "set print raw-frame-arguments"
A following patch will introduce options for the "backtrace" command,
based on some "set print" and "set backtrace" settings. There's one
setting in particular that is a bit annoying if we want to describe
the backtrace options and the settings commands using the same data
structures:
"set print raw frame-arguments"
The problem is that space between "raw" and "frame-arguments".
Calling the option
"bt -raw frame-arguments"
would be odd. So I'm calling the option
"bt -raw-frame-arguments"
instead.
And for consistency, this patch renames the set/show commands to:
"set print raw-frame-arguments"
"show print raw-frame-arguments"
I.e., dash instead of space. The old commands are left in place, but
marked deprecated.
We need to adjust a couple testcases, because the relevant tests use
gdb_test_no_output and the old commands are no longer silent:
(gdb) set print raw frame-arguments on
Warning: command 'set print raw frame-arguments' is deprecated.
Use 'set print raw-frame-arguments'.

Migrate rest of compile commands to new options framework
As I was in the neighbourhood, I converted the other "compile"
subcommands to the new options framework too. Specifically, "compile
code" and "compile file".
The user-visible changes are:
- All abbreviations of "-raw" are accepted now, instead of just -r.
Obviously that means "-ra" is now accepted.
- Option completion now works.
- "compile file" did not have a completer yet, and now it knows to
complete on filenames.
- You couldn't use "compile file" with a file named "-something".
You can now, with "compile file -- -something".

Make "print" and "compile print" support -OPT options
This patch adds support for "print -option optval --", etc.
Likewise for "compile print".
We'll get:
~~~~~~
(gdb) help print
Print value of expression EXP.
Usage: print [[OPTION]... --] [/FMT] [EXP]
Options:
-address [on|off]
Set printing of addresses.
-array [on|off]
Set pretty formatting of arrays.
-array-indexes [on|off]
Set printing of array indexes.
-elements NUMBER|unlimited
Set limit on string chars or array elements to print.
"unlimited" causes there to be no limit.
-max-depth NUMBER|unlimited
Set maximum print depth for nested structures, unions and arrays.
When structures, unions, or arrays are nested beyond this depth then they
will be replaced with either '{...}' or '(...)' depending on the language.
Use "unlimited" to print the complete structure.
-null-stop [on|off]
Set printing of char arrays to stop at first null char.
-object [on|off]
Set printing of C++ virtual function tables.
-pretty [on|off]
Set pretty formatting of structures.
-repeats NUMBER|unlimited
Set threshold for repeated print elements.
"unlimited" causes all elements to be individually printed.
-static-members [on|off]
Set printing of C++ static members.
-symbol [on|off]
Set printing of symbol names when printing pointers.
-union [on|off]
Set printing of unions interior to structures.
-vtbl [on|off]
Set printing of C++ virtual function tables.
Note: because this command accepts arbitrary expressions, if you
specify any command option, you must use a double dash ("--")
to mark the end of option processing. E.g.: "print -o -- myobj".
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I want to highlight the comment above about "--".
At first, I thought we could make the print command parse the options,
and if the option wasn't recognized, fallback to parsing as an
expression. Then, if the user wanted to disambiguate, he'd use the
"--" option delimiter. For example, if you had a variable called
"object" and you wanted to print its negative, you'd have to do:
(gdb) print -- -object
After getting that working, I saw that gdb.pascal/floats.exp
regressed, in these tests:
gdb_test "print -r" " = -1\\.2(499.*|5|500.*)"
gdb_test "print -(r)" " = -1.2(499.*|5|500.*)"
gdb_test "print -(r + s)" " = -3\\.4(499.*|5|500.*)"
It's the first one that I found most concerning. It regressed because
"-r" is the abbreviation of "-raw". I realized then that the behavior
change was a bit risker than I'd like, considering scripts, wrappers
around gdb, etc., and even user expectation. So instead, I made the
print command _require_ the "--" options delimiter if you want to
specify any option. So:
(gdb) print -r
is parsed as an expression, and
(gdb) print -r --
is parsed as an option.
I noticed that that's also what lldb's expr (the equivalent of print)
does to handle the same problem.
Going back the options themselves, note that:
- you can shorten option names, as long as unambiguous.
- For boolean options, 0/1 stand for off/on.
- For boolean options, "true" is implied.
So these are all equivalent:
(gdb) print -object on -static-members off -pretty on -- foo
(gdb) print -object -static-members off -pretty -- foo
(gdb) print -object -static-members 0 -pretty -- foo
(gdb) print -o -st 0 -p -- foo
TAB completion is fully supported:
(gdb) p -[TAB]
-address -elements -pretty -symbol
-array -null-stop -repeats -union
-array-indexes -object -static-members -vtbl
Note that the code is organized such that some of the options and the
"set/show" commands code is shared. In particular, the "print"
options and the corresponding "set print" commands are defined with
the same structures. The commands are installed with the
gdb::option::add_setshow_cmds_for_options function.

Introduce generic command options framework
This commit adds a generic command options framework, that makes it
easy enough to add '-'-style options to commands in a uniform way,
instead of each command implementing option parsing in its own way.
Options are defined in arrays of option_def objects (for option
definition), and the same options definitions are used for supporting
TAB completion, and also for generating the relevant help fragment of
the "help" command. See the gdb::options::build_help function, which
returns a string with the result of replacing %OPTIONS% in a template
string with an auto-generated "help" string fragment for all the
passed-in options.
Since most options in GDB are in the form of "-OPT", with a single
dash, this is the format that the framework supports.
I like to think of gdb's "-OPT" as the equivalent to getopt's long
options format ("--OPT"), and gdb's "/" as the equivalent to getopt's
short options format. getopt's short options format allows mixing
several one-character options, like "ls -als", kind of similar to
gdb's "x /FMT" and "disassemble /MOD", etc. While with gdb's "-"
options, the option is expected to have a full name, and to be
abbreviatable. E.g., "watch -location", "break -function main", etc.
This patch only deals with "-" options. The above comment serves more
to disclose why I don't think we should support mixing several
unrelated options in a single "-" option invocation, like "thread
apply -qcs" instead of "thread apply -q -c -s".
The following patches will add uses of the infrastructure to several
key commands. Most notably, "print", "compile print", "backtrace",
"frame apply" and "thread apply". I tried to add options to several
commands in order to make sure the framework didn't leave that many
open holes open.
Options use the same type as set commands -- enum var_types. So
boolean options are var_boolean, enum options are var_enum, etc. The
idea is to share code between settings commands and command options.
The "print" options will be based on the "set print" commands, and
their names will be the same. Actually, their definitions will be the
same too. There is a function to create "set/show" commands from an
array for option definitions:
/* Install set/show commands for options defined in OPTIONS. DATA is
a pointer to the structure that holds the data associated with the
OPTIONS array. */
extern void add_setshow_cmds_for_options (command_class cmd_class, void *data,
gdb::array_view<const option_def> options,
struct cmd_list_element **set_list,
struct cmd_list_element **show_list);
That will be used by several following patches.
Other features:
- You can use the "--" delimiter to explicitly indicate end of
options. Several existing commands use this token sequence for
this effect already, so this just standardizes it.
- You can shorten option names, as long as unambiguous. Currently,
some commands allow this (e.g., break -function), while others do
not (thread apply all -ascending). As GDB allows abbreviating
command names and other things, it feels more GDB-ish to allow
abbreviating option names too, to me.
- For boolean options, 0/1 stands for off/on, just like with boolean
"set" commands.
- For boolean options, "true" is implied, just like with boolean "set
commands.
These are the option types supported, with a few examples:
- boolean options (var_boolean). The option's argument is optional.
(gdb) print -pretty on -- *obj
(gdb) print -pretty off -- *obj
(gdb) print -p -- *obj
(gdb) print -p 0 -- *obj
- flag options (like var_boolean, but no option argument (on/off))
(gdb) thread apply all -s COMMAND
- enum options (var_enum)
(gdb) bt -entry-values compact
(gdb) bt -e c
- uinteger options (var_uinteger)
(gdb) print -elements 100 -- *obj
(gdb) print -e 100 -- *obj
(gdb) print -elements unlimited -- *obj
(gdb) print -e u -- *obj
- zuinteger-unlimited options (var_zuinteger_unlimited)
(gdb) print -max-depth 100 -- obj
(gdb) print -max-depth -1 -- obj
(gdb) print -max-depth unlimited -- obj
Other var_types could be supported, of course. These were just the
types that I needed for the commands that I ported over, in the
following patches.
It was interesting (and unfortunate) to find that we need at least 3
different modes to cover the existing commands:
- Commands that require ending options with "--" if you specify any
option: "print" and "compile print".
- Commands that do not want to require "--", and want to error out if
you specify an unknown option (i.e., an unknown argument that starts
with '-'): "compile code" / "compile file".
- Commands that do not want to require "--", and want to process
unknown options themselves: "bt", because of "bt -COUNT",
"thread/frame apply", because "-" is a valid command.
The different behavior is encoded in the process_options_mode enum,
passed to process_options/complete_options.
For testing, this patch adds one representative maintenance command
for each of the process_options_mode values, that are used by the
testsuite to exercise the options framework:
(gdb) maint test-options require-delimiter
(gdb) maint test-options unknown-is-error
(gdb) maint test-options unknown-is-operand
and adds another command to help with TAB-completion testing:
(gdb) maint show test-options-completion-result
See their description at the top of the maint-test-options.c file.
Docs/NEWS are in a patch later in the series.

number_or_range_parser::get_number, don't treat "1 -" as a range
While adding -OPT options to "frame apply level", I noticed that:
(gdb) frame apply level 0 -[TAB]
wasn't completing on the supported options. This commit fixes it.
We'll get instead:
(gdb) frame apply level 0 -
-c -past-entry -past-main -q -s
I added the isspace check because this case:
(gdb) frame apply level 0-
can't be an option.
Tests for this will be in a new gdb.base/options.exp file, in a
following patch. It will exercise all of:
(gdb) frame apply level 0-
(gdb) frame apply level 0 -
(gdb) frame apply level 0 --

boolean/auto-boolean commands, make "o" ambiguous
We currently accept "o" with boolean/auto-boolean commands, taking it
to mean "on". But "o" is ambiguous, between "on" and "off". I can't
imagine why assuming the user wanted to type "on" is a good idea, it
might have been a typo.
This commit makes gdb error out. We now get:
(gdb) maint test-settings set boolean o
"on" or "off" expected.
(gdb) maint test-settings set auto-boolean o
"on", "off" or "auto" expected.

New set/show testing framework (gdb.base/settings.exp)
This commit adds new representative commands for all types of settings
commands supported by gdb (enum var_types), and then uses them to
exercise settings parsing and completion.
(gdb) maint test-settings s[TAB]
set show
(gdb) maint test-settings set [TAB]
auto-boolean integer uinteger
boolean optional-filename zinteger
enum string zuinteger
filename string-noescape zuinteger-unlimited
(gdb) maint test-settings set enum [TAB]
xxx yyy zzz
etc.
This is basically unit testing, except that it goes fully via GDB. It
must be done this way in order to exercise TAB completion properly,
which must go via readline.

Remove "show" command completers, "set" command completers for string commands
The default command completer is symbol_completer, but it makes no
sense for a "show" command to complete on symbols, or anything else,
really.
I wonder whether we should instead make the default be no completer.
That seems like a much larger/complicated audit/change, so I'd like to
move forward with this version, as it'll be covered by tests. I
noticed this because a following patch will add a new
gdb.base/settings.exp testcase that exercises all sorts of details of
settings commands, including completing the show commands, using new
representative "maint test-settings <type or settings command>"
commands.
Also remove the completer for var_string and var_string_noescape
commands. No point in completing symbols when GDB is expecting a
string.

Fix TID parser bug
I noticed this inconsistency in the error messages below:
(gdb) print --1
Left operand of assignment is not an lvalue.
(gdb) thread apply 1 print --1
Thread 1 (Thread 0x7ffff7fb6740 (LWP 17805)):
inverted range
The "inverted range" error happens because get_number_trailer returns
0 to indicate error, but number_or_range_parser::get_number is not
checking for that. I tried detected the error there, but that doesn't
work because number_of_range_parser is used in places that _do_ want
to legitimately handle 0. IMO we should fix get_number_trailer's
interface or use something else when we want to parse 0 too.
I've decided to fix it in a different way, similarly to how
number_or_range_parser::finished was changed in commit 529c08b25ec7
("Add helper functions parse_flags and parse_flags_qcs").
Seems like a good change, even if we tweaked
number_or_range_parser::get_number, as it simplifies
thread_apply_command and makes them consistent with
number_or_range_parser::finished().
We now get the same error message in both cases:
(gdb) print --1
Left operand of assignment is not an lvalue.
(gdb) thread apply 1 print --1
Thread 1 (Thread 0x7ffff7fb6740 (LWP 17805)):

Fix latent bug with custom word point completers
Completion routines that use a custom word point, and that then
recurse into complete_line (e.g., if we make "thread apply" a custom
word point completer, and complete on the command passed as argument),
we stumble on this latent bug:
(gdb) thread apply all pri[TAB]
(gdb) thread apply all priprint
The problem is that there's a spot in complete_line_internal_1 that
rewinds the completion word but does not reflect that change in the
custom word point in the tracker. This patch fixes it.

Fix latent bug in custom word point completion handling
Without this fix, if we switch the "print" completer to custom word
point handling, we regress gdb.base/completion.exp like this:
(gdb) p "break1.c FAIL: gdb.base/completion.exp: complete 'p "break1' (timeout)
The problem is that completing an expression that starts with double
quotes, and resolves to a filename, like this:
(gdb) p "break1[TAB]
would change from this, with current master:
(gdb) p "break1.c"|
^^^^^^^^^^|
\- cursor here
to this:
(gdb) p "break1.c |
^^^^^^^^^^|
\- quote replaced by space
The issue is that completer.c:advance_to_completion_word misses
telling the completion tracker to emulate readline's handling of
completing a string when rl_find_completion_word returns a delimiter.
This commit fixes the latent bug.

cpu/or1k: Add support for orfp64a32 spec
This patch adds support for OpenRISC 64-bit FPU operations on 32-bit cores by
using register pairs. The functionality has been added to OpenRISC architecture
specification version 1.3 as per architecture proposal 14[0].
For supporting assembly of both 64-bit and 32-bit precision instructions we have
defined CGEN_VALIDATE_INSN_SUPPORTED. This allows cgen to use 64-bit bit
architecture assembly parsing on 64-bit toolchains and 32-bit architecture
assembly parsing on 32-bit toolchains. Without this the assembler has issues
parsing register pairs.
This patch also contains a few fixes to the symantics for existing OpenRISC
single and double precision FPU operations.

Dwarf: Don't add nameless modules to partial symbol table
A name for BLOCK DATA in Fortran is optional. If no name has been
assigned, GDB crashes during read-in of DWARF when BLOCK DATA is
represented via DW_TAG_module. BLOCK DATA is used for one-time
initialization of non-pointer variables in named common blocks.
As of now there is no issue when gfortran is used as DW_TAG_module is
not emitted. However, with Intel ifort the nameless DW_TAG_module is
present and has the following form:
...
<1><dd>: Abbrev Number: 7 (DW_TAG_module)
<de> DW_AT_decl_line : 46
<df> DW_AT_decl_file : 1
<e0> DW_AT_description : (indirect string, offset: 0x110): block
data
<e4> DW_AT_high_pc : 0x402bb7
<ec> DW_AT_low_pc : 0x402bb7
...
The missing name leads to a crash in add_partial_symbol, during length
calculation.

Move gdb's xmalloc and friends to new file
When "common" becomes a library, linking will cause a symbol clash,
because "xmalloc" and some related symbols are defined in that
library, libiberty, and readline.
To work around this problem, this patch moves the clashing symbols to
a new file, which is then compiled separately for both gdb and
gdbserver.

Remove linux-waitpid.c debugging code
The debugging code in linux-waitpid.c is one of the few remaining
spots that depends on the gdb/gdbserver difference.
My first thought was that this code is not extremely useful, so this
patch removes this code. (However, if it is actually useful to
someone, we could make it work by introducing a new abstraction.)

Remove trailing newlines from help text
I noticed recently that some command had a trailing newline in its
"help" output. So, I temporarily hacked cli-decode.c to print
something when a new command was installed that had a trailing newline
in its help message, and wrote this patch, which removes all the ones
I could find this way. (There could still be a few more in *-nat
files.)
Tested on x86-64 Fedora 29.

[gdb/testsuite] Fix remove-inferiors.exp FAIL with readnow board
We see this failure with the readnow board:
...
FAIL: gdb.multi/remove-inferiors.exp: load binary
...
When running with board readnow, an extra message "Expanding full symbols" is
emitted after the "Reading symbols" message, and the regexp corresponding to
the FAIL only allows the first message.
Fix this by allowing the extra message in the regexp.

[gdb/testsuite] Fix main high_pc in nonvar-access.exp
When running gdb.dwarf2/nonvar-access.exp with board readnow, we have:
...
FAIL: gdb.dwarf2/nonvar-access.exp: print/x def_implicit_s
...
and 12 more similar failures.
I've tracked this down to the range of main being hardcoded to
[_main, _main+0x10000) in the dwarf assembly:
...
DW_TAG_subprogram {
{name main}
{DW_AT_external 1 flag}
{low_pc [gdb_target_symbol main] DW_FORM_addr}
{high_pc [gdb_target_symbol main]+0x10000 DW_FORM_addr}
} {
...
which overlaps with the .debug_info for the elf-init.c CU (containing
__libc_csu_init and __libc_csu_fini).
Fix this by using function_range to find the actual range of main.

gdb: Check for not allocated/associated values during array slicing
When extracting an array slice we should give up if the array is
not-allocated or not-associated. For Fortran, at least in gfortran
compiled code, the upper and lower bounds are undefined if the array
is not allocated or not associated, in which case performing checks
against these bounds will result in undefined behaviour.
Better then to throw an error if we try to slice such an array. This
changes the error message that the user will receive in these
cases (if they got an error message before). Previously they may have
gotten "slice out of range" now they'll get "array not allocated" or
"array not associated".

* valops.c (value_slice): Check for not allocated or not
associated values.

* gdb.fortran/vla-sizeof.exp: Update expected results.

The structure of this index is:

adress area : [0x28, 0x3c) : size 0x14
symbol table : [0x3c, 0x203c) : size 0x2000
constant pool: [0x203c, 0x203c): size 0x0
EOF : 0x203c
...
Note that the symbol table consists entirely of empty slots (where an empty
slot is a pair of 32-bit zeroes), and that the constant pool is empty.
The problem happens here in mapped_index_base::build_name_components:
...
auto count = this->symbol_name_count ();
for (offset_type idx = 0; idx < count; idx++)
{
if (this->symbol_name_slot_invalid (idx))
continue;
const char *name = this->symbol_name_at (idx);
...
when accessing the slot at idx == 0 in the symbol table,
symbol_name_slot_invalid returns false so we calculate name, which is
calculated using 'constant_pool + symbol_table[idx].name', which means we get
name == constant_pool. And given that the constant pool is empty, name now
points past the memory allocated for the index, and when we access name[0] for
the first time in cp_find_first_component_aux, we run into the
heap-buffer-overflow.
Fix this by fixing the definition of symbol_name_slot_invalid:
...
- return bucket.name == 0 && bucket.vec;
+ return bucket.name == 0 && bucket.vec == 0;
...

The problem happens in linespec_lexer_lex_string when lexing

else if (PARSER_STREAM (parser) - start > 4

[gdb/symtab] Fix symbol loading performance regression
The commit "[gdb/symtab] Fix language of duplicate static minimal symbol"
introduces a performance regression, when loading a cc1 executable build with
-O0 -g and gcc 7.4.0. The performance regression, measured in 'real' time is
about 175%.
The slower execution comes from the fact that the fix in symbol_set_names
makes the call to symbol_find_demangled_name unconditional.
Fix this by reverting the commit, and redoing the fix as follows.
Recapturing the original problem, the first time symbol_set_names is called
with gsymbol.language == lang_auto and linkage_name == "_ZL3foov", the name is
not present in the per_bfd->demangled_names_hash hash table, so
symbol_find_demangled_name is called to demangle the name, after which the
mangled/demangled pair is added to the hashtable. The call to
symbol_find_demangled_name also sets gsymbol.language to lang_cplus.
The second time symbol_set_names is called with gsymbol.language == lang_auto
and linkage_name == "_ZL3foov", the name is present in the hash table, so the
demangled name from the hash table is used. However, the language of the
symbol remains lang_auto.
Fix this by adding a field language in struct demangled_name_entry, and using
the field in symbol_set_names to set the language of gsymbol, if necessary.
Tested on x86_64-linux.

Remove newlines from warnings
ARI pointed out that a recent patch introduced a call to "warning"
with a string that ended in a newline:
https://sourceware.org/ml/gdb-patches/2019-06/msg00000.html
This is generally forbidden, I believe, because warning adds its own
newline.
This patch removes all of the trailing newlines I was able to find. I
searched for 'warning (.*\\n"' and then fixed the ones where the
newline appeared at the end of the string (some had internal
newlines).

Use gdbpy_enter in py-breakpoint.c
A few spots in py-breakpoint.c acquire the GIL manually. However,
because these spots generate events, and because events are expected

Python globals are set correctly.

Mention in the description of the `-rpath' LD option the restrictions

only documented along with the `-rpath-link' option, which may not be

Apply substitute-path to relative filenames as well
When source file path is relative to the build directory (which
is considered a good practice and is enforced in certain buildsystems,
such as meson), gdb only applies substitute-path to the build directory
path. Then gdb appends the source file path to the rewritten build
directory path, and tries to access that.
This fails if either two of the following conditions are true:
a) The user didn't specify substitute-path for the build directory.
This is highly likely, since path substitution for build directories
is not documented anywhere, and since gdb does not tell[0] the user
the path to the build directory, just the source file path.
b) The source file path changed.
This can also easily happen, since a source path that is relative
to the build directory can include any number of directory names
that are not part of the program source tree (starting with the
name of the root directory of the source tree). Gdb will not apply
substitute-path to that relative path, thus there is no way for
the user to tell gdb about these changes.
This commit changes the code to apply substitute-path to all filenames,
both relative and absolute. This way it is possible to do things like:
set substitute-path ../foobar-1.0 /src/my/foobar-1.0
which is completely in line with the user expectations.
This might break unusual cases where build directory path is also
relative (is that even possible?) and happens to match the path
to the source directory (i.e. happens to match a substitution rule).
[0]: There's a "maintenance info symtabs" command that does show the names
of the build directories, but normal users are not required to
know or use that.

Add timestamps to "maint time" output
Currently "maint time" will print the amount of time a command took.
Sometimes, though, it's useful to have a timestamp as well -- for
example if one is correlating a gdb log with some other log.
This patch adds a timestamp to the start and end of each command when
this setting is in effect.
This also removes a "//" comment and changes scoped_command_stats to
use DISABLE_COPY_AND_ASSIGN; two minor things I noticed while working
on the patch.
Tested on x86-64 Fedora 29.

[BFD, AArch64] Fix PT_GNU_PROPERTY alignment issue
If the new GNU property section was being created by the linker
(this will happen only if none of the inputs have any GNU property
section but the command line to the linker forces a bti with
--force-bti), the alignment of the section and hence the program
header of PT_GNU_PROPERTY type was not being set correctly. This
patch fixes this issue.

gdb/riscv: Don't error when decoding a 6 or 8 byte instruction
If the RISC-V prologue scanner finds a 6 or 8 byte instruction we
currently throw an internal error, which is not great for the user.
A mechanism already exists in the prologue scanner to leave
instructions marked as unknown so that we can stop the prologue scan
without raising an error, this is used for all 2 and 4 byte
instructions that are not part of the small set the prologue scanner
actually understands.
This commit changes GDB so that all 6 and 8 byte instructions are
marked as unknown, rather than causing an error.

Introduce and use make_unique_xstrdup
Adds an utility function to make it shorter to write the common case
of wrapping an xstrdup with a unique_xmalloc_ptr, and uses it
throughout.
Note: I tried to put this in common/common-utils.h near skip_spaces,
etc. but that is included in common/common-defs.h before
common/gdb_unique_ptr.h is included, so it would fail to compile
because gdb::unique_xmalloc_ptr isn't defined at that point yet. I
tried moving the gdb_unique_ptr.h inclusion before common-utils.h, but
that doesn't work because gdb_unique_ptr.h depends on common-utils.h
for xfree.

libctf: look for BSD versus GNU qsort_r signatures
We cannot just look for any declaration of qsort_r, because some
operating systems have a qsort_r that has a different prototype
but which still has a pair of pointers in the right places (the last two
args are interchanged): so use AC_LINK_IFELSE to check for both
known variants of qsort_r(), and swap their args into a consistent order
in a suitable inline function. (The code for this is taken almost
unchanged from gnulib.)
(Now we are not using AC_LIBOBJ any more, we can use a better name for
the qsort_r replacement as well.)

Author: Philippe Waroquiers <philippe.waroquiers@skynet.be>
Date: Fri May 31 14:00:47 2019 +0200
Improve usability and/or readibility of help and apropos output.
The "help" command can output long list of command names or classes.
Use the title style to style the command names or classes to make
the output more readable.
Similarly, change "apropos" command to also style the command names.
It is sometimes unclear why "apropos REGEXP" lists some commands,
and then the user has to manually do 'help command' for all commands
listed by "apropos" to see more details about the matching commands.
=> Add an optional flag -v so that "apropos -v REGEXP":
* outputs the full documentation of matching commands.
* highlights the documentation parts matching REGEXP.

Add highlight style, title style, fputs_highlighted. Improve 'show style'
Have 'show style' and its subcommands using a style to style its output.
This allows the GDB user or developer to use 'show style' to visually see

Add 2 new styles highlight style, title style and fputs_highlighted function.
Highlight style is used by fputs_highlighted to highlight the parts of
its char *STR argument that match a HIGHLIGHT regexp.
This (and the title style) will be used in a following patch.

Implement | (pipe) command.
The pipe command allows to run a GDB command, and pipe its output
to a shell command:
(gdb) help pipe
Send the output of a gdb command to a shell command.
Usage: | [COMMAND] | SHELL_COMMAND
Usage: | -d DELIM COMMAND DELIM SHELL_COMMAND
Usage: pipe [COMMAND] | SHELL_COMMAND
Usage: pipe -d DELIM COMMAND DELIM SHELL_COMMAND
Executes COMMAND and sends its output to SHELL_COMMAND.
The -d option indicates to use the string DELIM to separate COMMAND
from SHELL_COMMAND, in alternative to |. This is useful in
case COMMAND contains a | character.
With no COMMAND, repeat the last executed command
and send its output to SHELL_COMMAND.
(gdb)
For example:
(gdb) pipe print some_data_structure | grep -B3 -A3 something
The pipe character is defined as an alias for pipe command, so that
the above can be typed as:
(gdb) | print some_data_structure | grep -B3 -A3 something
If no GDB COMMAND is given, then the previous command is relaunched,
and its output is sent to the given SHELL_COMMAND.
This also defines convenience vars $_shell_exitcode and $_shell_exitsignal
to record the exit code and exit signal of the last shell command
launched by GDB e.g. by "shell", "pipe", ...

Add previous_saved_command_line to allow a command to repeat a previous command.
Currently, a previous command can be repeated when the user types an
empty line. This is implemented in handle_line_of_input by
returning saved_command_line in case an empty line has been input.
If we want a command to repeat the previous command, we need to save
the previous saved_command_line, as when a command runs, the saved_command_line
already contains the current command line of the command being executed.
As suggested by Tom, the previous_saved_command_line is made static.
At the same time, saved_command_line is also made static.
The support functions/variables for the repeat command logic are now all
located inside top.c.

libctf: fix a number of build problems found on Solaris and NetBSD
- Use of nonportable <endian.h>
- Use of qsort_r
- Use of zlib without appropriate magic to pull in the binutils zlib
- Use of off64_t without checking (fixed by dropping the unused fields
that need off64_t entirely)
- signedness problems due to long being too short a type on 32-bit
platforms: ctf_id_t is now 'unsigned long', and CTF_ERR must be
used only for functions that return ctf_id_t
- One lingering use of bzero() and of <sys/errno.h>
All fixed, using code from gnulib where possible.
Relatedly, set cts_size in a couple of places it was missed
(string table and symbol table loading upon ctf_bfdopen()).

Don't crash is dwarf_decode_macro_bytes's 'body' is NULL, even when '!is_define'
Ref.: https://bugzilla.redhat.com/show_bug.cgi?id=1715008
On commit 7bede82892a06e6c26989803e70f53697392dcf9 ("Don't crash if
dwarf_decode_macro_bytes's 'body' is NULL"), I was too strict when
checking if 'body' is NULL: the check only comprised the case when
'is_define' is true. However, the corruption of .debug_macro by
rpmbuild's "debugedit" also affects the case when 'is_define' is
false, i.e., when the macro is being undefined.
This commit improves the check and covers both cases now. This has
been tested on Fedora 30 with a problematic debuginfo, and I don't see
a segfault anymore.
OK to push?

Fix crash in cp_print_value_fields
PR c++/20020 concerns a crash in cp_print_value_fields. The immediate
cause is that cp_print_value_fields does not handle the case where
value_static_field fails. This is fixed in this patch by calling
cp_print_static_field from the "try" block.
Digging a bit deeper, the error occurs because GCC does not emit a
DW_AT_const_value for a static constexpr member appearing in a
template class. I've filed a GCC bug for this.
Tested on x86-64 Fedora 29.

Add "set print finish"
A user wanted to be able to disable the display of the value when
using "finish" -- but still have the value entered into the value
history in case it was useful later on. Part of the rationale here is
that sometimes the value might be quite large, or expensive to display
(in their case this was compounded by a rogue pretty-printer).
This patch implements this idea.

Remove find_old_style_renaming_symbol
We found a case where a "bt" was very slow with Ada code. Profiling
with callgrind showed this to be primarily due to calls to
find_old_style_renaming_symbol. Because new-style renaming symbols
were implemented in 2007, it seems safe enough to remove this old
code.
A "-batch -ex bt" test on a large Ada program improves from:
13.23user 0.57system 0:13.82elapsed 99%CPU (0avgtext+0avgdata 571408maxresident)k
to

binutils: CTF support for objdump and readelf
This introduces CTF support for objdump and readelf. objdump has the
following new arguments:
--ctf=SECTION: display CTF in the given SECTION
--ctf-parent=SECTION: name of CTF section that is the parent of this section
readelf has the above, and these two as well:
--ctf-symbols=SECTION: name of symbol table section (optional)
--ctf-strings=SECTION: name of string table section (optional)
(objdump can always use BFD machinery to determine the applicable string
and symbol tables automatically, so these arguments are unnecessary.)
Nearly all the work is done by the ctf_dump machinery in libctf: most of
the remaining work is option-processing and section-reading, and thus is
different for objdump and readelf: the minimal amount of similar code
remaining is, in my view, too small to share, particularly given that
objdump uses ctf_bfdopen() and readelf uses ctf_simple_open() since it
doesn't have a bfd.
I am not particularly satisfied with the way resources are freed in
either of these (I was forced to do it at the top level, for lack of
anywhere else to free resources allocated during option processing), but
I can't see any better way to do it without introducing new
infrastructure for no other purpose.
There are essentially arbitrary ordering changes to the Makefile.in's
order of libtool-related stuff that I can't get rid of, but they have no
semantic effect. (It is possible that some hunks of these changes could
be dropped, but that seems a bit risky to me.)

This facility allows you to associate regions of type IDs with *labels*,
a labelled tiling of the type ID space. You can use these to define

space, or to assist with parallelization of CTF processing, or for any
other purpose you can think of.
Notably absent from here (though declared in the API header) is any way
to define new labels: this will probably be introduced soon, as part of
the linker deduplication work. (One existed in the past, but was deeply
tied to the Solaris CTF file generator and had to be torn out.)

libctf: lookups by name and symbol
These functions allow you to look up types given a name in a simple
subset of C declarator syntax (no function pointers), to look up the
types of variables given a name, and to look up the types of data
objects and the type signatures of functions given symbol table offsets.
(Despite its name, one function in this commit, ctf_lookup_symbol_name(),
is for the internal use of libctf only, and does not appear in any
public header files.)

libctf: core type lookup
Finally we get to the functions used to actually look up and enumerate
properties of types in a container (names, sizes, members, what type a
pointer or cv-qual references, determination of whether two types are
assignment-compatible, etc).
With a very few exceptions these do not work for types newly added via
ctf_add_*(): they only work on types in read-only containers, or types
added before the most recent call to ctf_update().
This also adds support for lookup of "variables" (string -> type ID
mappings) and for generation of C type names corresponding to a type ID.

libctf: ELF file opening via BFD
These functions let you open an ELF file with a customarily-named CTF
section in it, automatically opening the CTF file or archive and
associating the symbol and string tables in the ELF file with the CTF
container, so that you can look up the types of symbols in the ELF file
via ctf_lookup_by_symbol(), and so that strings can be shared between
the ELF file and CTF container, to save space.
It uses BFD machinery to do so. This has now been lightly tested and
seems to work. In particular, if you already have a bfd you can pass
it in to ctf_bfdopen(), and if you want a bfd made for you you can
call ctf_open() or ctf_fdopen(), optionally specifying a target (or
try once without a target and then again with one if you get
ECTF_BFD_AMBIGUOUS back).
We use a forward declaration for the struct bfd in ctf-api.h, so that
ctf-api.h users are not required to pull in <bfd.h>. (This is mostly
for the sake of readelf.)

libctf: mmappable archives
If you need to store a large number of CTF containers somewhere, this
provides a dedicated facility for doing so: an mmappable archive format
like a very simple tar or ar without all the system-dependent format
horrors or need for heavy file copying, with built-in compression of
files above a particular size threshold.
libctf automatically mmap()s uncompressed elements of these archives, or
uncompresses them, as needed. (If the platform does not support mmap(),
copying into dynamically-allocated buffers is used.)
Archive iteration operations are partitioned into raw and non-raw
forms. Raw operations pass thhe raw archive contents to the callback:
non-raw forms open each member with ctf_bufopen() and pass the resulting
ctf_file_t to the iterator instead. This lets you manipulate the raw
data in the archive, or the contents interpreted as a CTF file, as
needed.
It is not yet known whether we will store CTF archives in a linked ELF
object in one of these (akin to debugdata) or whether they'll get one
section per TU plus one parent container for types shared between them.
(In the case of ELF objects with very large numbers of TUs, an archive
of all of them would seem preferable, so we might just use an archive,
and add lzma support so you can assume that .gnu_debugdata and .ctf are
compressed using the same algorithm if both are present.)
To make usage easier, the ctf_archive_t is not the on-disk
representation but an abstraction over both ctf_file_t's and archives of
many ctf_file_t's: users see both CTF archives and raw CTF files as
ctf_archive_t's upon opening, the only difference being that a raw CTF
file has only a single "archive member", named ".ctf" (the default if a
null pointer is passed in as the name). The next commit will make use
of this facility, in addition to providing the public interface to
actually open archives. (In the future, it should be possible to have
all CTF sections in an ELF file appear as an "archive" in the same
fashion.)
This machinery is also used to allow library-internal creators of
ctf_archive_t's (such as the next commit) to stash away an ELF string
and symbol table, so that all opens of members in a given archive will
use them. This lets CTF archives exploit the ELF string and symbol
table just like raw CTF files can.
(All this leads to somewhat confusing type naming. The ctf_archive_t is
a typedef for the opaque internal type, struct ctf_archive_internal: the
non-internal "struct ctf_archive" is the on-disk structure meant for
other libraries manipulating CTF files. It is probably clearest to use
the struct name for struct ctf_archive_internal inside the program, and
the typedef names outside.)

Date: Wed Apr 24 10:17:13 2019 +0100
libctf: opening
This fills in the other half of the opening/creation puzzle: opening of
already-existing CTF files. Such files are always read-only: if you
want to add to a CTF file opened with one of the opening functions in
this file, use ctf_add_type(), in a later commit, to copy appropriate
types into a newly ctf_create()d, writable container.
The lowest-level opening functions are in here: ctf_bufopen(), which
takes ctf_sect_t structures akin to ELF section headers, and
ctf_simple_open(), which can be used if you don't have an entire ELF
section header to work from. Both will malloc() new space for the
buffers only if necessary, will mmap() directly from the file if
requested, and will mprotect() it afterwards to prevent accidental
corruption of the types. These functions are also used by ctf_update()
when converting types in a writable container into read-only types that
can be looked up using the lookup functions (in later commits).
The files are always of the native endianness of the system that created
them: at read time, the endianness of the header magic number is used to
determine whether or not the file needs byte-swapping, and the entire
thing is aggressively byte-swapped.
The agggressive nature of this swapping avoids complicating the rest of
the code with endianness conversions, while the native endianness
introduces no byte-swapping overhead in the common case. (The
endianness-independence code is also much newer than everything else in
this file, and deserves closer scrutiny.)
The accessors at the top of the file are there to transparently support
older versions of the CTF file format, allowing translation from older
formats that have different sizes for the structures in ctf.h:
currently, these older formats are intermingled with the newer ones in
ctf.h: they will probably migrate to a compatibility header in time, to
ease readability. The ctf_set_base() function is split out for the same
reason: when conversion code to a newer format is written, it would need
to malloc() new storage for the entire ctf_file_t if a file format
change causes it to grow, and for that we need ctf_set_base() to be a
separate function.
One pair of linked data structures supported by this file has no
creation code in libctf yet: the data and function object sections read
by init_symtab(). These will probably arrive soon, when the linker comes
to need them. (init_symtab() has hardly been changed since 2009, but if
any code in libctf has rotted over time, this will.)
A few simple accessors are also present that can even be called on
read-only containers because they don't actually modify them, since the
relevant things are not stored in the container but merely change its
operation: ctf_setmodel(), which lets you specify whether a container is
LP64 or not (used to statically determine the sizes of a few types),
ctf_import(), which is the only way to associate a parent container with
a child container, and ctf_setspecific(), which lets the caller
associate an arbitrary pointer with the CTF container for any use. If
the user doesn't call these functions correctly, libctf will misbehave:
this is particularly important for ctf_import(), since a container built
against a given parent container will not be able to resolve types that
depend on types in the parent unless it is ctf_import()ed with a parent
container with the same set of types at the same IDs, or a superset.
Possible future extensions (also noted in the ctf-hash.c file) include
storing a count of things so that we don't need to do one pass over the
CTF file counting everything, and computing a perfect hash at CTF
creation time in some compact form, storing it in the CTF file, and
using it to hash things so we don't need to do a second pass over the
entire CTF file to set up the hashes used to go from names to type IDs.
(There are multiple such hashes, one for each C type namespace: types,
enums, structs, and unions.)

libctf: creation functions
The CTF creation process looks roughly like (error handling elided):
int err;
ctf_file_t *foo = ctf_create (&err);
ctf_id_t type = ctf_add_THING (foo, ...);
ctf_update (foo);
ctf_*write (...);
Some ctf_add_THING functions accept other type IDs as arguments,
depending on the type: cv-quals, pointers, and structure and union
members all take other types as arguments. So do 'slices', which
let you take an existing integral type and recast it as a type
with a different bitness or offset within a byte, for bitfields.
One class of THING is not a type: "variables", which are mappings
of names (in the internal string table) to types. These are mostly
useful when encoding variables that do not appear in a symbol table
but which some external user has some other way to figure out the
address of at runtime (dynamic symbol lookup or querying a VM
interpreter or something).
You can snapshot the creation process at any point: rolling back to a
snapshot deletes all types and variables added since that point.
You can make arbitrary type queries on the CTF container during the
creation process, but you must call ctf_update() first, which
translates the growing dynamic container into a static one (this uses
the CTF opening machinery, added in a later commit), which is quite
expensive. This function must also be called after adding types
and before writing the container out.
Because addition of types involves looking up existing types, we add a
little of the type lookup machinery here, as well: only enough to
look up types in dynamic containers under construction.

We now enter a series of commits that are sufficiently tangled that
avoiding forward definitions is almost impossible: no attempt is made to

libctf: hashing
libctf maintains two distinct hash ADTs, one (ctf_dynhash) for wrapping
dynamically-generated unknown-sized hashes during CTF file construction,
one (ctf_hash) for wrapping unchanging hashes whose size is known at
creation time for reading CTF files that were previously created.
In the binutils implementation, these are both fairly thin wrappers
around libiberty hashtab.
Unusually, this code is not kept synchronized with libdtrace-ctf,
due to its dependence on libiberty hashtab.

libctf: low-level list manipulation and helper utilities
These utilities are a bit of a ragbag of small things needed by more
than one TU: list manipulation, ELF32->64 translators, routines to look
up strings in string tables, dynamically-allocated string appenders, and
routines to set the specialized errno values previously committed in
<ctf-api.h>.
We do still need to dig around in raw ELF symbol tables in places,
because libctf allows the caller to pass in the contents of string and
symbol sections without telling it where they come from, so we cannot
use BFD to get the symbols (BFD reasonably demands the entire file). So
extract minimal ELF definitions from glibc into a private header named
libctf/elf.h: later, we use those to get symbols. (The start-of-
copyright range on elf.h reflects this glibc heritage.)

XCOFF linker segmentation fault
The XCOFF linker temporarily trims the output bfd section list,
without adjusting section_count to suit. This is a little rude, but
the dwarf line number code can easily cope with this situation. So
check for a NULL end of list as well as limiting the saved section
VMAs to the first section_count list entries.

Fix failure on powerpc 32-bit only targets
Targets that lack ppc64 support were failing the new prefix-reloc
test. This patch adds some test infrastructure to deal with that, and
changes the powerpc gas usage info so that "-a64" is omitted when
unsupported.
I've been meaning to break up the usage message for a long time;
While doing so causes translators some work now, it should make it
easier next time a new powerpc option is added.

aarch64: add STO_AARCH64_VARIANT_PCS and DT_AARCH64_VARIANT_PCS
The bottom 2 bits of st_other are used for visibility, the top 6 bits are
de facto reserved for processor specific use. This patch defines a
bits to mark function symbols that follow a variant procedure call standard
with different register usage convention.
A dynamic tag is also defined that marks modules with R_<CLS>_JUMP_SLOT
relocations referencing symbols marked with STO_AARCH64_VARIANT_PCS.
This can be used by dynamic linkers that support lazy binding to decide
what registers need to be preserved during symbol resolution.

gdb/riscv: Improve flen length determination
This solves an assertion failure when a remote provides a target
description which only refers to floating point registers by their
hardware name (e.g. f0), rather than their ABI name (e.g. ft0). GDB
assumed that should the floating point register feature be presented,
it would contain a register called ft0.
The floating point length is now instead determined by searching for
the same register, but looking for any of its aliases.
gdb/ChangeLog:
* riscv-tdep.c (riscv_gdbarch_init): Support determining flen from
target descriptions using exclusively floating point register name
aliases.

gdb/fortran: Handle gdbarch_floatformat_for_type returning nullptr
In this commit:
commit 34d11c682fd96c7dbe3ebd6cd9033e65d51ec7a3
Date: Fri May 3 15:23:55 2019 +0100
gdb/fortran: Use floatformats_ia64_quad for fortran 16-byte floats
GDB was changed such that the Fortran's 16-byte float format was
obtained by calling gdbarch_floatformat_for_type instead of just using
gdbarch_long_double_format as it was before.
The problem with this default_floatformat_for_type can return NULL in
some cases, and the code introduced in 34d11c682f didn't consider
this.
This commit introduces several alternative strategies for finding a
suitable 16-byte floating point type. First GDB calls
gdbarch_floatformat_for_type (this was what 34d11c682f added), if this
returns null GDB will use gdbarch_long_double_format if it is the
correct size (this was the format used before 34d11c682f). Finally,
if neither of the above provides a suitable type then GDB will create
a new dummy type.
This final dummy type is unlikely to provide an correct debug
experience as far as examining the 16-byte floats, but it should
prevent GDB crashing.

[gdb/cli] Fix use of uninitialized variable in complete_command
When building gdb on ubuntu 16.04 with gcc 5.4.0, and running the gdb
testsuite we run into:
...
FAIL: gdb.linespec/explicit.exp: complete after -line: \
cmd complete "b -line argument " (timeout)
...
The failure is reproducible outside the testsuite like this:
...
$ gdb -q build/gdb/testsuite/outputs/gdb.linespec/explicit/explicit \
-ex "complete b -line argument"
Reading symbols from \
build/gdb/testsuite/outputs/gdb.linespec/explicit/explicit...
terminate called after throwing an instance of 'std::length_error'

Aborted (core dumped)
...
The problem is here in complete_command:
...
completion_result result = complete (arg, &word, "e_char);
std::string arg_prefix (arg, word - arg);
if (result.number_matches != 0)
...
The problem is that the word variable is not initialized when
result.number_matches == 0, but the variable is still used in the arg_prefix
initialization.
Fix this by guarding the arg_prefix initialization with the
'result.number_matches != 0' test.

AArch64: Implement choice between Cortex-A53 erratum workarounds. (PR ld/24373)
The Cortex-A53 erratum currently has two ways it can resolve the erratum when
using the flag --fix-cortex-a53-843419:
1) If the address is within the range of an ADR instruction it rewrites the ADRP
into an ADR, and those doesn't need the use of a veneer.
2) If the address is not within range, it adds a branch to a veneer which will
execute the final bit of the erratum workaround and branch back to the call
site.
When we do this we always generate the veneers and we always align the size of
the text section to 4KB. This is because we only know which workaround we can
use after all linking has finished and all addresses are known. This means even
though the veneers are not used, we still generate the section and we still
change the size of the input section.
This is problematic for small memory devices as this would require the user to
take about a ~4KB hit in memory even though it's not even used.
Since there's no real way to restart the linking process from the final write
phase this patch solves the issue by allowing the user more control over which
erratum workaround gets used.
Concretely this changes the option --fix-cortex-a53-843419 to take optional
arguments --fix-cortex-a53-843419[=full|adr|adrp]
- full (default): Use both ADRP and ADR workaround. This is equivalent to not
specifying any options and is the default behavior before this
patch.
- adr: Only use the ADR workaround, this will not cause any increase in binary
size but linking will fail if the referenced address is out of range of
an ADR instruction.
- adrp: Use only the ADRP workaround, this will never rewrite your ADRP.
In the cases where the user knows how big their binaries are the `adr` option
would prevent the unneeded overhead.

Fix PR 24571 - Relaxation does not shorten jmp or call to target at pc-relative range boundary
The range check done to transform an absolute call/jump to a pc-relative one is
off-by-one, and that causes this shortening optimization to be missed if the
branch target is right at the range boundary.
In the non-shrinkable case, the range is what is mentioned in the ISA - -4094
bytes in the backward direction, and 4096 bytes in the positive direction.
In the shrinkable case, the forward jump range increases by two bytes (deleted
because of the shortening from call/jmp to rcall/rjmp), and therefore, the
range is -4094 in the reverse, and 4098 in the positive direction.
Fix the ranges for !shrinkable and shrinkable cases, and add a test caes to
ensure jumps to max forward and backward ranges get relaxed to rjmp.

Fix PR 24564 - link fails for some rcalls/rjmps with wraparound
The current code to compute relative distance in the wrap around case does not
handle the edge case of the target (after adjusting for implicit PC increment)
being exactly half of the wrap around distance. This patch fixes that and adds a
testcase.
The range for a forward relative jump call is 4096 bytes ((2 * 2047) + (2 bytes
for the implicit PC increment)). If the target of the jump is at a distance of
4098 bytes, it is out of range for a forward jump - however, a backward jump can
still reach that address if pmem-wrap-around is 8192.
Assume address 0 has rjmp to address 4098. With a wrap around of 8192 and
*without* adjusting for the implicit PC increment of 2 bytes, rjmp .-4096 will
jump to address 4096 (wrap around at 8192 and decreasing addresses from then
on). Adjusting 2 bytes for the implicit PC increment, the actual target is 4098.
avr_relative_distance_considering_wrap_around though, does the wrap around only
if the passed in distance is less than half of the wrap around distance. In this
case, it is exactly equal to half (original distance 4098, adjusted distance of
4096 and wraparound of 8192), and the bypassed wrap around causes the reloc
overflow error.
Fix by wrapping around even if adjusted distance is equal to half of wrap around
distance.

GAS: Replace macro LITERAL_PREFIXDOLLAR_HEX with a runtime value.
In an upcoming commit, I need to be able to set the prefix used
to introduce hexadecimal literal constants using a command line
flag. This is not currently possible, because the switch which
determines this (LITERAL_PREFIXDOLLAR_HEX) is a macro set at
build time.
This change substitutes it for a variable to be set at start up.
gas/ChangeLog:
* expr.c (literal_prefix_dollar_hex): New variable.
(operand)[case '$']: Use the new variable instead of the old macro.
* expr.h (literal_prefix_dollar_hex): Declare it.
* config/tc-epiphany.c (md_begin): Assign literal_prefix_dollar_hex.
* config/tc-ip2k.c: ditto
* config/tc-mt.c: ditto
* config/tc-epiphany.h (LITERAL_PREFIXDOLLAR_HEX): Remove macro definition.

gdb/fortran: Use floatformats_ia64_quad for fortran 16-byte floats
PR gdb/18644 is caused by GDB using the wrong floating point format
for gfortran's 16-byte floating point type, including when the 16-byte
float is used as the component of a 32-byte complex type.
This commit addresses the issue in two places, first in i386-tdep.c,
there is already some code to force the use of floatformats_ia64_quad
for specific named types, this is extended to include the type names
that gfortran uses for its 16-byte floats.
Second, the builtin 16-byte float type (in f-lang.c) is changed so it
no longer uses gdbarch_long_double_format. On i386 this type is not
16-bytes, but is smaller, this is not what gfortran is expecting.
Instead we now use gdbarch_floatformat_for_type and ask for a
16-byte (128 bit) type using the common gfortran type name. This is
then spotted in i386-tdep.c (thanks to the first change above) and we
again get floatformats_ia64_quad returned.
This patch was tested on X86-64/GNU-Linux using '--target_board=unix'
and '--target_board=unix/-m32', and resolves all of the known failures
associated with PR gdb/18644. I've also added the test case from the
original bug report.

testsuite: Add replay logging to GDBSERVER_DEBUG
Add "replay" to the list of GDBSERVER_DEBUG options. This will
cause a gdbserver.replay file to be written to the test output
directory.
At the same time switch this to a comma separated list in order
to easily handle all possible options.
The replay log is created by GDB, but has been added to
GDBSERVER_DEBUG as it is only required for gdbserver tests. To
enable it, the gdb_debug_init is overridden to allow the additional
checking, before calling the original function.

testsuite: Record all gdb input to gdb.in
When debugging testsuite failures, it can be awkward parsing gdb.log to
obtain all the commands run in order to manually re-run the test.
This patch adds the functionality to save all gdb commands to the file gdb.in
when the testsuite is run. The file is saved in the directory for the test and
if gdb is restarted then .1, .2, .3 etc is added to the filename.
Once a test has been run, the .in file can be used to re-run the test in the
following way:
gdb -x outputs/gdb.store/gdb.in outputs/gdb.store/store
The code works by intercepting send_gdb. I've added a TYPE to ensure that any
commands that would destroy the playback are kept from the log (for example the
Y from an answer to a y/n question).
Adds library function standard_output_file_with_gdb_instance to open a file
postfixed with count of the gdb instance. Ensure this count is reset when a new
.exp script is run.
I've re-run a random selection of .in files to check they do not error. Logs with
commands such as "attach <pid>" will not directly work when re-run.

Add debug redirect option
Currently, when logging is enabled, output will be sent to both a
logfile and standard terminal output. The redirect option sends output
only to the logfile. This includes all debug output.
Add the option to redirect debug output seperately to normal
output, using the cli command:
set logging debugredirect on
By setting this and enabling logging, all output and debug will
be sent to the logfile. The user will still see all output but
no debug output.
This causes a change in behaviour for anyone currently using
logging redirect, as now only output will be redirected. Users
will have to issue the additional command above to also redirect
debug.

This error happens as follows.
The function find_partial_die has a cu argument, but returns a pdi which may
or may not be from that cu:
...
/* Find a partial DIE at OFFSET, which may or may not be in CU,
except in the case of .debug_types DIEs which do not reference
outside their CU (they do however referencing other types via
DW_FORM_ref_sig8). */
static struct partial_die_info *
find_partial_die (sect_offset sect_off, int offset_in_dwz, struct dwarf2_cu *cu)
...
So the pdi returned by find_partial_die here in partial_die_parent_scope may
be from another cu:
...
partial_die_parent_scope (struct partial_die_info *pdi,
struct dwarf2_cu *cu)
{
const char *grandparent_scope;
struct partial_die_info *parent, *real_pdi;
/* We need to look at our parent DIE; if we have a DW_AT_specification,
then this means the parent of the specification DIE. */
real_pdi = pdi;
while (real_pdi->has_specification)
real_pdi = find_partial_die (real_pdi->spec_offset,
real_pdi->spec_is_dwz, cu);
parent = real_pdi->die_parent;
...
in which case both real_pdi and parent will be not from cu, but from another
one, say cu2.
Subsequently, cu's comp_unit_obstack is used to set parent->scope:
...
parent->scope = typename_concat (&cu->comp_unit_obstack,
grandparent_scope,
parent->name, 0, cu);
...
So, we use cu->comp_unit_obstack to assign a value to the scope field of
a pdi belonging to cu2, and when cu is deleted, the scope field points to a
freed value.
Fix this by making find_partial_die return the cu corresponding to the
returned pdi, and handling this at the call sites.
Tested on x86_64-linux.

Make stap-probe.c:stap_parse_register_operand's "regname" an std::string
This patch simplifies the code of

Fix darwin-nat.c build
John Marshall pointed out that darwin-nat.c fails to build:
CXX darwin-nat.o
../../../binutils-gdb/gdb/darwin-nat.c:1709:8: error: must use 'class' tag to refer to type 'thread_info' in this scope

class 'thread_info' is hidden by a non-type declaration of 'thread_info' here

Mach has a thread_info() function declared in that header, which darwin-nat.c #includes.

Don't crash if dwarf_decode_macro_bytes's 'body' is NULL
Hi,
Ref.: https://bugzilla.redhat.com/show_bug.cgi?id=1708192
https://bugzilla.redhat.com/show_bug.cgi?id=1708786
During the Fedora RPM build process, gdb-add-index is invoked to
extract the DWARF index from the binary, and GDB will segfault because
dwarf2read.c:parse_definition_macro's 'body' variable is NULL.
The underlying problem is that Fedora's rpm-build's "debugedit"
program will silently corrupt .debug_macro strings when a binary is
compiled with -g3. This is being taken care of by Mark Wielaard,
here:
https://bugzilla.redhat.com/show_bug.cgi?id=1708786
However, I still feel it's important to make GDB more resilient
against invalid DWARF input, so I'm proposing this rather simple patch
to catch the situation when "body == NULL" (i.e., it's probably been
corrupted) and issue a complaint. This is not a real fix to the
problem, of course, but at least GDB is able to finish without
segfaulting.
OK for master?

GDB (s12z): Improve reliability of the stack unwinder.
Previously, the stack unwinder searched through consecutive bytes for values

This was error prone, because such bytes could also be the operands of other
instructions. This change uses the opcodes api to interpret the code in each
frame.

Fix assertion failure in coerce_unspec_val_to_type
coerce_unspec_val_to_type does:
set_value_address (result, value_address (val));
However, this is only valid for lval_memory. This patch changes this
code to only set the address for lval_memory values.
This seems like an ordinary oversight in coerce_unspec_val_to_type,
and a test case would be difficult to write, so I'm submitting it
without a test case.
Tested on x86-64 Fedora 29; plus using an Ada program that exhibits
the bug (but which cannot be shared).

[gdb/testsuite] Fix base address selection entry encoding in dw2-skip-prologue.S
A base address selection entry in a location list consist of two (constant or
relocated) address offsets. The two offsets are the same size as an address
on the target machine.
The test-case gdb.dwarf2/dw2-skip-prologue.S encodes a base address selection
entry using .4byte, which is incorrect for 8-byte pointer size. [ Which
triggers an assert in dwz, see PR dwz/24172. ]

Fix GDB build when using --disable-gdbmi
Since commit
b4be1b064860 ("Fix MI output for multi-location breakpoints")
we get this error when building with --disable-gdbmi:
CXXLD gdb
/home/smarchi/src/binutils-gdb/gdb/breakpoint.c:6358: error: undefined reference to 'mi_multi_location_breakpoint_output_fixed(ui_out*)'
This is due to breakpoint.c using a function defined in mi/mi-main.c, even
though mi/mi-main.c isn't included in the build.
To fix it, use the flags feature of ui_out. mi_ui_out has the new
fix_multi_location_breakpoint_output flag set for versions >= 3. Also,
move the global variable fix_multi_location_breakpoint_output to
breakpoint.c, so it can be read there even when we build without MI. I
renamed it to fix_multi_location_breakpoint_output_globally so it
doesn't clash with the new enumerator.
gdb/ChangeLog:
* breakpoint.h (fix_multi_location_breakpoint_output_globally):
New variable declaration.
* breakpoint.c (fix_multi_location_breakpoint_output_globally):
New variable.

cc-with-tweaks: show dwz stderr and verify result
When running the gdb.base/index-cache.exp test case with the
cc-with-dwz-m board, I noticed that the final executable didn't actually
contain a .gnu_debugaltlink section with the name of the external dwz
file:
$ readelf --debug-dump=links testsuite/outputs/gdb.base/index-cache/index-cache
* empty *
Running dwz by hand, I realized it's because dwz complains that the
output .debug_info section is empty and fails:
$ gcc ~/src/binutils-gdb/gdb/testsuite/gdb.base/index-cache.c -g3 -O0 -o a && cp a b
$ dwz -m foo a b
dwz: foo: .debug_info section not present
$ echo $?
1
This is because index-cache.c is trivial (just an empty main) and dwz
doesn't find anything to factor out to the dwz file. [1]
I think that cc-with-tweaks should fail in this scenario: if the user
asks for an external dwz file to be generated (the -m flag), then it
should be an error if cc-with-tweaks doesn't manage to produce an
executable with the proper link to this external dwz file. Otherwise,
the test runs with a regular non-dwzified executable, which gives a
false sense of security about whether the feature under test works with
dwzified executables.
So this patch adds checks for that after invoking dwz. It also removes
the 2>&1 to allow the error message to be printed like so:
Running /home/smarchi/src/binutils-gdb/gdb/testsuite/gdb.base/index-cache.exp ...
gdb compile failed, dwz: /home/smarchi/build/binutils-gdb/gdb/testsuite/outputs/gdb.base/index-cache/index-cache.dwz: .debug_info section not present
- In the -m case (multi-file compression), we check if the expected output file
exists.
- In the -z case (single-file compression), we check if the file
contents has changed. This should catch cases where dwz doesn't modify the
file because it's not worth it.
It was chosen not to check for dwz's exit code, as it is not very
reliable up to dwz 0.12.
With this patch, fewer tests will pass than before with the
cc-with-dwz and cc-with-dwz-m boards, but those were false positives
anyway, as the test ran with regular executables.
[1] Note that dwz has been patched by Tom de Vries to work correctly in
this case, so we can use dwz master to run the test:

[binutils][aarch64] New sve_size_bh iclass.
Add new iclass sve_size_bh to handle instructions that have two variants
encoded with the SVE_sz field.
This iclass behaves the same as the sve_size_sd iclass, but it has a
nicer name for those instructions that choose between variants using the
"B" and "H" size qualifiers.

[binutils][aarch64] SVE2 feature extension flags.
Include all feature flag macros.
The "sve2" extension that enables the core sve2 instructions.
This also enables the sve extension, since sve is a requirement of sve2.
Extra optional sve2 features are the bitperm, sm4, aes, and sha3 extensions.
These are all given extra feature flags, "bitperm", "sve2-sm4",
"sve2-aes", and "sve2-sha3" respectively.
The sm4, aes, and sha3 extensions are explicitly marked as sve2
extensions to distinguish them from the corresponding NEON extensions.
Rather than continue extending the current feature flag numbers, I used
some bits that have been skipped.

[gdb/testsuite] Fix gdb.arch/amd64-entry-value-paramref.S
The file gdb.arch/amd64-entry-value-paramref.S contains a DIE for function
bar:
...
DIE29: .uleb128 0x2 # (DIE (0x29) DW_TAG_subprogram)
.ascii "bar\0" # DW_AT_name
.byte 0x1 # DW_AT_decl_file (gdb.arch/amd64-entry-value-paramref.cc)
.byte 0x15 # DW_AT_decl_line
.long DIE45 # DW_AT_type
.byte 0x1 # DW_AT_inline
...
which refers to DIE45:
...
DIE45: .uleb128 0x4 # (DIE (0x45) DW_TAG_base_type)
.byte 0x4 # DW_AT_byte_size
.byte 0x5 # DW_AT_encoding
.ascii "int\0" # DW_AT_name
...
using a form DW_FORM_ref4:
...
.uleb128 0x2 # (abbrev code)
.uleb128 0x2e # (TAG: DW_TAG_subprogram)
.byte 0x1 # DW_children_yes
...
.uleb128 0x49 # (DW_AT_type)
.uleb128 0x13 # (DW_FORM_ref4)
...
However, the DW_FORM_ref4 is a CU-relative reference, while using a label for
the value will result in a section-relative value.
So, if linked in object files contain dwarf info and are placed in the
.debug_info section before the compilation units generated from
amd64-entry-value-paramref.S, then the referenced type is at 0x108:
...
<1><108>: Abbrev Number: 4 (DW_TAG_base_type)
<109> DW_AT_byte_size : 4
<10a> DW_AT_encoding : 5 (signed)
<10b> DW_AT_name : int
...
but the reference will point to a non-existing DIE at 0x1cf:
...
<1><f0>: Abbrev Number: 2 (DW_TAG_subprogram)
<f1> DW_AT_name : bar
<f5> DW_AT_decl_file : 1
<f6> DW_AT_decl_line : 21
<f7> DW_AT_type : <0x1cf>
<fb> DW_AT_inline : 1 (inlined)
...
which happens to cause a GDB internal error described in PR23270 - "GDB
internal error: dwarf2read.c:18656: internal-error: could not find partial
DIE 0x1b7 in cache".
Fix the invalid DWARF by making the reference value CU-relative:
...
- .long DIE45 # DW_AT_type
+ .long DIE45 - .Ldebug_info0 # DW_AT_type
...
Tested on x86_64-linux.

When debugging a mixed Ada/C program using this scenario:
- set print frame-arguements all
- an Ada function named pck.call_me calls a C function named break_me
- you put a breakpoint in break_me and the program reaches this
breakpoint.
Now display the backtrace:
(gdb) bt
#0 break_me () at [...]
#1 0x000000000040243e in pck.call_me (
s={P_ARRAY = 0x7fffffffe21c, P_BOUNDS = 0x41e6e8}) at [...]
whereas we should expect:
(gdb) bt
#0 break_me () at [...]
#1 0x000000000040243e in pck.call_me (s="test") at [...]
The problem is that GDB prints the S parameter in the pck.call_me Ada
function using the current language, so the C one, because the program
is stopped in a C function, whereas it should use the pck.call_me frame
one. This behavior is ok when user manually changes the language but it's
not the right one when language is auto.
This patch fixes this problem so now when using auto language, all Ada
frame arguments are printed using Ada like syntax when the frame is part
of Ada code, even if the program is stopped in a frame using a different
language.
If the user explicitly sets a language (using "set language ...") then
no change here, all the Ada frame arguments are printed using this
language.

Fix style bug when paging
Philippe pointed out a styling bug that would occur in some conditions
when paging:
https://sourceware.org/ml/gdb-patches/2019-04/msg00101.html
I was finally able to reproduce this, and this patch fixes the bug.
The problem occurred when text overflowed the line, causing a
pagination prompt, but when no wrap column had been set. In this
case, the current style was reset to show the prompt, but then not
reset back to the previously applied style before emitting the rest of
the line.
The fix is to record the applied style in this case, and re-apply it
afterward -- but only if the pager prompt was emitted, something that
the existing style.exp pointed out on the first, more naive, version
of the patch.
Tested on x86-64 Fedora 29.

Correctly handle non-C-style arrays in c_get_string
A user here noticed that the Python Value.string method did not work
for Ada arrays. I tracked this down to an oddity in value_as_address
-- namely, it calls coerce_array, but that function will not force
array coercion when the language has c_style_arrays=false, as Ada
does.
This patch fixes the problem by changing c_get_string so that arrays
take the "in GDB's memory" branch. The actual patch is somewhat more
complicated than you might think, because the caller can request more
array elements than the type allows. This is normal when the type is
using the C struct hack.
Tested on x86-64 Fedora 29.

Change ptype/o to print bit offset
Consider this short C example:
struct inner
{
unsigned x;
unsigned y : 3;
unsigned z : 3;
};
struct outer
{
unsigned char o : 3;
struct inner i __attribute__ ((packed));
};
When I use "ptype/o" on this, I get:
(gdb) ptype/o struct outer
/* offset | size */ type = struct outer {
/* 0: 5 | 1 */ unsigned char o : 3;
/* XXX 5-bit hole */
/* 1 | 8 */ struct inner {
/* 1 | 4 */ unsigned int x;
/* 5:29 | 4 */ unsigned int y : 3;
/* 5:26 | 4 */ unsigned int z : 3;
/* XXX 2-bit padding */
/* XXX 3-byte padding */
/* total size (bytes): 8 */
} i;
/* total size (bytes): 9 */
}
In the location of "o" ("0: 5"), the "5" means "there are 5 bits left
relative to the size of the underlying type.
I find this very difficult to follow. On irc, Sergio said that this
choice came because it is what pahole does. However, I think it's not
very useful, and maybe is just an artifact of the way that
DW_AT_bit_offset was defined in DWARF 3.
This patch changes ptype/o to print the offset of a bitfield in a more
natural way, that is, using the bit number according to the platform's
bit numbering.
With this patch, the output is now:

This is better, IMO, because now the "offset" of a bitfield is
consistent with the offset of an ordinary member, referring to its
offset from the start of the structure.

Fix ptype/o comment formatting
I noticed that ptype/o will print:
/* 3: 3 | 1 */ signed char a4 : 2;
/* XXX 3-bit hole */
That is, "*/" at the end of the "hole" message does not line up with
the other comment ends. I thought it would be a bit nicer if this did
line up, so I fixed it. Then, to my surprise, I found that I could
not make ptype-offsets.exp fail.
I still am not sure why it doesn't fail, but changing the tests to use
string_to_regexp and changing the quoting helped. This in turn showed
that some of the existing test cases were wrong, so I've also updated
them here.

Fix VLA printing for Ada
While looking at a different Ada problem, I found that printing a
record containing a VLA did not work properly.
I tracked the problem down to dwarf2_evaluate_property trying, and
failing, to compare two types that differed only in qualifiers.
This patch changes dwarf2_evaluate_property to ignore qualifiers when
comparing types.

gas/elf dwarf2 tests
Make them work for tile, by using ".quad 0" as the simulated
instruction and doubling size of aligns. The larger aligns tripped
over riscv alignment handling, fixed by adding -mno-relax there.
Also disable link-relax for avr, pru and xtensa, allowing these
targets to pass these tests. With link-time relaxation enabled,
these targets emit alignment relocations rather than aligning at
assembly time. This means the assembler doesn't see a change in PC
when it is expected over an alignment frag and thus view numbers are
calculated incorrectly.

xfail locview tests on mep that use complex relocs for view numbers
Expressions that compute view numbers that aren't simplified early
enough to a constant end up being selected for representation as
complex relocations, enabled on mep-* targets.
It would be possible to recognize such expressions, that can resolve
to constants, but this problem was hit before, in preexisting tests,
so xfail the new hits similarly.
The new hits were caused by yesterday's patch to dwarf2dbg.c: views in
the beginning of subsections are now computed later, based on the

[gdb/testsuite] Fix ls_host return in index-cache.exp
When adding a debug print here in index-cache.exp:
...
proc_with_prefix test_cache_disabled { cache_dir } {
lassign [ls_host $cache_dir] ret files_before
+ puts "before: '$files_before'"
+ exit
...
we have:
...
files_before: ''
...
When further adding:
...
proc_with_prefix test_cache_disabled { cache_dir } {
+ exec touch $cache_dir/foo.1 $cache_dir/foo.2 $cache_dir/foo.3
...
we have:
...
files_before: 'foo.1'
...
while we're expecting file_before to contain foo.[123].
Fix this by making the return statement in ls_host return a list rather than a
string (in accordance with the ls_host documentation), after which we have:
...
files_before: 'foo.1 foo.2 foo.3'
...

[gdb/testsuite] Fix .debug_aranges in watch-loc.c
When running gdb.dlang/watch-loc.exp with target board cc-with-debug-names, we
run into:
...
FAIL: gdb.dlang/watch-loc.exp: disassemble _Dmain (GDB internal error)
...
in more detail:
...
(gdb) disassemble _Dmain
gdb/dwarf2read.c:5293: internal-error: \
compunit_symtab* dw2_find_pc_sect_compunit_symtab(objfile*, \
bound_minimal_symbol, CORE_ADDR, obj_section*, int): \
Assertion `result != NULL' failed.
...
The problem is that the .debug_aranges section in watch-loc.c contains a
debug_info_offset which is set to 0:
...
asm (
" .pushsection .debug_aranges,\"\",%progbits\n"
" .4byte .Laranges_end - .Laranges_start\n"
".Laranges_start:\n"
" .2byte 0x2\n"
" .4byte 0\n"
...
while the compilation unit at offset 0 in the .debug_section in the executable
is in fact not the compilation unit generated from watch-loc-dw.S.
[ Note: this is a non-trivial test-case. The file watch-loc-dw.S contains a
.debug_info section, but not an .debug_aranges section or any actual code.
The file watch-loc.c contains code and a .debug_aranges section, but no other
debug section. So, the intent for the .debug_aranges section in watch-loc.c
is to refer to a compilation unit in the .debug_info section in
watch-loc-dw.S. ]
This happens when linked in object files contain dwarf info and are placed in
the .debug_info section before the compilation units generated from
watch-loc.c and watch-loc-dw.S.
Fix this by defining the debug_info_offset field using a label .Lcu1_begin
that defines the start of an empty .debug_section compilation unit:
...
asm (
+ " .pushsection .debug_info,\"\",%progbits\n"
+ ".Lcu1_begin:"
+ " .popsection\n"
" .pushsection .debug_aranges,\"\",%progbits\n"
" .4byte .Laranges_end - .Laranges_start \n"
".Laranges_start:\n"
" .2byte 0x2\n"
- " .4byte 0\n"
+ " .4byte .Lcu1_begin\n"
...
which during linking merges with the start of the .debug_info section of
watch-loc-dw.S.
Tested on x86_64-linux with native, cc-with-gdb-index and cc-with-debug-names.

[gdb/testsuite] Fix handling of DW_FORM_ref_addr in dwarf assembler
When running gdb.dwarf2/multidictionary.exp with target board cc-with-dwz and
current dwz, we run into a dwz abort:
...
gdb compile failed, gdb/contrib/cc-with-tweaks.sh: line 188: 11484 Aborted \
(core dumped) $DWZ "$output_file" > /dev/null 2>&1
UNTESTED: gdb.dwarf2/multidictionary.exp: multidictionary.exp
...
The dwz abort (PR dwz/24169) is caused by an invalid DW_FORM_ref_addr in the
multidictionary binary.
The multidictionary binary is build from multidictionary.S which is generated
using the dwarf assembler, and multidictionary.S contains dwarf for 3
compilation units.
In multidictionary0.o (generated from multidictionary.S), we find a concrete
formal parameter DIE:
...
<2><dc>: Abbrev Number: 4 (DW_TAG_formal_parameter)
<dd> DW_AT_abstract_origin: <0xa6>
...
referring to an abstract formal parameter DIE at 0xa6:
...
<2><a6>: Abbrev Number: 8 (DW_TAG_formal_parameter)
<a7> DW_AT_name : msg
<ab> DW_AT_type : <0x92>
...
but in the multidictionary binary the concrete formal parameter DIE is still
referring to 0xa6:
...
<2><1a3>: Abbrev Number: 4 (DW_TAG_formal_parameter)
<1a4> DW_AT_abstract_origin: <0xa6>
...
while the abstract formal parameter DIE has moved to 0x16d:
...
<2><16d>: Abbrev Number: 8 (DW_TAG_formal_parameter)
<16e> DW_AT_name : msg
<172> DW_AT_type : <0x159>
...
The concrete formal parameter DIE is specified in multidictionary.S like this:
...
.Llabel21:
.uleb128 4
.4byte .Llabel17 - .Lcu1_begin
...
The problem is that the .Lcu1_begin label is assumed to mark the start of the
.debug_info section in the executable, but in fact it marks the start of the
first compilation unit from multidictionary.S in the executable. Usually
these two entities are the same, but they are not when linked in object files
contain dwarf info and are placed in the .debug_info section before the
compilation units generated from multidictionary.S.
Fix this in the dwarf assembler by generating instead the label itself:
...
.Llabel21:
.uleb128 4
.4byte .Llabel17
...
resulting in a relocation in the object file:
...
Offset Info Type Sym. Value Sym. Name + Addend
0000000000dd 00040000000a R_X86_64_32 0000000000000000 .debug_info + a6
...
and resulting in the correct offset in the executable:
...
<2><1a3>: Abbrev Number: 4 (DW_TAG_formal_parameter)
<1a4> DW_AT_abstract_origin: <0x16d>
...

[LVu] base subseg head view on prev subseg's tail
Location views at borders between subsegments/subsections in the same
segment/section are computed as if each new subsegment/subsection
started with a forced view reset to zero, but the line number program
does not introduce resets that are not explicitly requested, so if a
subsegment ends at the same address another starts, the line number
program will have a continuity of views at the border address, whereas
the initial view number label in the latter subsegment will be
miscomputed as zero.
This patch delays the assignment of view expressions at subsegment
heads to the time of chaining the frags of subsegments into a single
segment, so that they are set based on the view at the end of the
previous subsegment in the same segment.
The line number program created for the test program had an
unnecessary DW_LNS_advance_pc at the end. This patch also arranges
for us not to emit it.

Don't derive partial_symbol from general_symbol_info
This patch partly reverts commit 8a6d42345 ("Change representation of
psymbol to flush out accessors"); specifically, it changes
partial_symbol to no longer derive from general_symbol_info.
The basic problem here is that the bcache compares objects bitwise,
and this change made it less likely that the relevant fields in the
psymbol would be fully initialized. This could be seen by running a
test under valgrind on the Fedora-i686 buildbot.
I considered a simpler patch, namely just zeroing the psymbol's
"value" field in add_psymbol_to_bcache. However, it wasn't clear to
me that this memset could not then be optimized away by the compiler.
Regression tested by the buildbot. I think this should go in 8.3 as
well.

m32c padding with nops
m32c_md_end attempted to pad out a code section with nops, but this
was just plain wrong in many ways:
- The padding didn't happen at all if the last section emitted wasn't
a code section.
- The padding went to the wrong place if subsections were used, and
the last subseg used wasn't the highest numbered subseg.
- Padding wasn't added to all code sections.
- If the last section was empty, it was padded to 4 bytes.
- The padding didn't go to a 4-byte alignment boundary, instead it
effectively made the last instruction 4 bytes in size.
- The padding didn't take into account that code sections may have
contents other than machine instructions.
So, rip it out and handle nop padding properly, also fixing .align
.balign/.p2align in the middle of code.

PR24511, nm should not mark symbols in .init_array as "t"
This patch restricts the section names matched in coff_section_type,
a function that translates section names to symbol type, and arranges
to translate section flags to symbol type before looking at names.
The latter change resulted in various test failures due to improper
section flags being used in tests, and by the plugin support, so fix
that too.
The new test fails on many ELF targets that lack .init/fini_array
in their scripts. I've just xfailed those. pru-elf oddly defines
__init_array_begin rather than __init_array_start. I've left that
target as a FAIL, and pj-elf too which reports an error for undefined
weak symbols.

Fix cast of character to enum type in Ada
An internal bug report points out that, when a global character enum
type is used, casting fails, like:
(gdb) print global_char_enum'('F')
$1 = 70
The bug here turns out to be that enumerators are qualified, so for
example the mangled name might be "pck__QU48", rather than "QU48".
This patch fixes the problem by only examining the suffix of the
enumerator. This is ok because the type is already known, and because
the mangling scheme ensures that there won't be clashes.

On MS-Windows, define _WIN32_WINNT in a single common place.
This changeset defines _WIN32_WINNT to at least 0x0501, the level
of Windows XP, unless defined to a higher level, in a single
place. It then removes all the overrides of _WIN32_WINNT in
individual files as no longer needed. Doing this also solves
compilation of windows-nat.c with mingw.org's MinGW, as that
file uses CONSOLE_FONT_INFO which needs the XP level to become
exposed in the Windows headers, while mingw.org defaults to
Windows 9X.

Fix lookup of separate debug file on MS-Windows.
If you put the separate debug file in a global debug directory, GDB on
MS-Windows would fail to find it. This happens because we obtain the
directory to look up the debug file by concatenating the debug
directory name with the leading directories of the executable, and the
latter includes the drive letter on MS-Windows. So we get an invalid
file name like
d:/usr/lib/debug/d:/usr/bin/foo.debug
This commit fixes that by removing the colon of the drive letter,
thus producing
d:/usr/lib/debug/d/usr/bin/foo.debug

gdb/rust: Handle printing structures containing strings
When printing a rust structure that contains a string GDB can
currently fail to read the fields that define the string. This is
because GDB mistakenly treats a value that is the parent structure as
though it is the structure that defines the string, and then fails to
find the fields needed to extract a string.
The solution is to create a new value to represent the string field of
the parent value.

[gdb/testsuite] Fix "unable to find usable gdb" error with cc-with-tweaks.exp
When running fullpath-expand.exp with target_board=dwarf4-gdb-index, we run
into:
...
$ make check-gdb RUNTESTFLAGS="--target_board=dwarf4-gdb-index fullpath-expand.exp"
Running src/gdb/testsuite/gdb.base/fullpath-expand.exp ...
gdb compile failed, cc-with-tweaks.sh: unable to find usable gdb
=== gdb Summary ===
nr of untested testcases 1
...
The same happens with fullname.exp.
The dwarf4-gdb-index.exp board file includes cc-with-tweaks.exp, which uses
cc-with-tweaks.sh, which calls gdb-add-index.sh.
The gdb-add-index.sh script uses a gdb executable, defaulting to gdb:
...
GDB=${GDB:=gdb}
...
The cc-with-tweaks.sh script tries to ensure that the build gdb executable is
used by gdb-add-index.sh:
...
if [ -z "$GDB" ]
then
if [ -f ./gdb ]
then
GDB="./gdb -data-directory data-directory"
elif [ -f ../gdb ]
then
GDB="../gdb -data-directory ../data-directory"
elif [ -f ../../gdb ]
then
GDB="../../gdb -data-directory ../../data-directory"
else
echo "$myname: unable to find usable gdb" >&2
exit 1
fi
fi
...
So, if the current directory is build/gdb/testsuite, then a gdb executable
build/gdb/testsuite/../gdb will be used.
However, in the case of fullpath-expand.exp the test cd's into the sources:
...
set saved_pwd [pwd]
cd $srcdir
set err [gdb_compile "${subdir}/${srcfile} ${subdir}/${srcfile2}" $binfile \
executable {debug}]
cd $saved_pwd
...
and cc-with-tweaks.sh generates the "unable to find usable gdb" error.
The same error occurs if we use --target_board=cc-with-dwz instead (only in
this case we actually don't need gdb, we just need the GDB variable to be set
in cc-with-tweaks.sh, which arguably is a bug in cc-with-tweaks.sh).
Fix both errors in cc-with-tweaks.exp by generating a gdb script gdb.sh using
$GDB, $GDBFLAGS and $INTERNAL_GDBFLAGS and passing this script to
cc-with-tweaks.sh by setting env(GDB).

gdb/windows-nat.c: Get rid of main_thread_id global
This global is meant to point to the "main" thread of execution of
the program we are debugging. It is set when attaching to a process
or when receiving a CREATE_PROCESS_DEBUG_EVENT event. The theory at
the time was that this was also going to be the thread receiving
the EXIT_PROCESS_DEBUG_EVENT event.
Unfortunately, we have discovered since then that this is actually
not guaranteed. What this means in practice is that there is moderate
risk that main_thread_id refers to a thread which no longer exists.
This global is used in 3 situations:
- OUTPUT_DEBUG_STRING_EVENT
- LOAD_DLL_DEBUG_EVENT
- UNLOAD_DLL_DEBUG_EVENT
It's not clear why we would need to use the main_thread_id in those cases
instead of using the thread ID provided by the kernel events itself.
So this patch implements this approach, which then allows us to delete
the main_thread_id global.

* windows-nat.c (main_thread_id): Delete.
(handle_output_debug_string): Replace main_thread_id by
current_event.dwThreadId.

(Windows) fix thr != nullptr assert failure in delete_thread_1
We have observed that GDB would randomly trip the following
assertion failure when debugging on Windows. When allowing
the program to run until the inferior exits, we occasionally see:
(gdb) cont
Continuing.
[Thread 48192.0xd100 exited with code 1]
[Thread 48192.0x10ad8 exited with code 1]
[Thread 48192.0x36e28 exited with code 0]

../../src/gdb/thread.c:453: internal-error: void delete_thread_1(thread_inf
o*, bool): Assertion `thr != nullptr' failed.
Running the same scenario with some additional traces enabled...
(gdb) set verbose
(gdb) set debugevents
... allows us to understand what the issue is. To understand, we need
to first look at the events received when starting the program, and
in particular which threads got created how. First, we get a
CREATE_PROCESS_DEBUG_EVENT for tid=0x442a8:
gdb: kernel event for pid=317536 tid=0x442a8 code=CREATE_PROCESS_DEBUG_EVENT)
Shortly after, we get some CREATE_THREAD_DEBUG_EVENT events,
one of them being for tid=0x4010c:
gdb: kernel event for pid=317536 tid=0x4010c code=CREATE_THREAD_DEBUG_EVENT)
Fast forward a bit of debugging, and we do a "cont" as above,
at which point the programs reaches the end, and the system reports
"exit" events. The first interesting one is the following:
gdb: kernel event for pid=317536 tid=0x442a8 code=EXIT_THREAD_DEBUG_EVENT)
This is reporting a thread-exit event for a thread whose tid
is the TID of what we call the "main thread". That's the thread
that was created when we received the CREATE_PROCESS_DEBUG_EVENT
notification, and whose TID is actually stored in a global variable
named main_thread_id. This is not something we expected, as
the assumption we made was that the main thread would exit last,
and we would be notified of it via an EXIT_PROCESS_DEBUG_EVENT.
But apparently, this is not always true, at least on Windows Server
2012 and 2016 where this issue has been observed happening randomly.
The consequence of the above notification is that we call
windows_delete_thread for that thread, which removes it from
our list of known threads.
And a little bit later, then we then get the EXIT_PROCESS_DEBUG_EVENT,
and we can see that the associated tid is not the main_thread_id,
but rather the tid of one of the threads that was created during
the lifetime of the program, in this case tid=0x4010c:
gdb: kernel event for pid=317536 tid=0x4010c code=EXIT_PROCESS_DEBUG_EVENT)
And the debug trace printed right after shows why we're crashing:
[Deleting Thread 317536.0x442a8]
We are trying to delete the thread whose tid=0x442a8, which is
the main_thread_id! As we have already deleted that thread before,
the search for it returns a nullptr, which then trips the assertion
check in delete_thread_1.
This commit fixes this issue. It ignores the open question of
what to do with the main_thread_id global, particularly after
that thread has been removed from our list of threads. This will
be dealt with as a separate patch, to allow cherry-picking
this patch into a release branch.
For now, we fix the code so as to avoid this crash.
gdb/ChangeLog:
* windows-nat.c (get_windows_debug_event) <EXIT_PROCESS_DEBUG_EVENT>:
Use current_event.dwThreadId instead of main_thread_id.

Fix "catch exception" with dynamic linking
When an Ada program is dynamically linked against libgnat, and when
one of the standard exceptions is used, the exception object may be
referenced by the main executable using a copy relocation.
In this situation, a "catch exception" for those exceptions will not
manage to stop. This happens because, under the hood, "catch
exception" creates an expression object that examines the object
addresses -- but in this case, the address will be incorrect.
This patch fixes the problem by arranging for these filter expressions
to examine all the relevant minimal symbols. This way, the object
from libgnat will be found as well.

Fix crash in dwarf2read.c with template parameters
PR c++/24470 concerns a crash in dwarf2read.c that occurs with a
particular test case.
The issue turns out to be that process_structure_scope will pass NULL
to symbol_symtab. This happens because new_symbol decided not to
create a symbol for the particular DIE.
This patch fixes the problem by finding another reasonably-appropriate
symtab to use instead; issuing a complaint if one cannot be found for
some reason.
As mentioned in the bug, I think there are other bugs here. For
example, when using "ptype" on the "l" object in the test case, I
think I would expect to see the template parameter. I didn't research
this too closely, since it seemed more important to fix the crash.
Tested on x86-64 Fedora 29.
I'd like to check this in to the 8.3 branch as well.

gdb/fortran: print function arguments when printing function type
Before this commit using ptype on a Fortran function will include
information about the functions return type, but not the expected
arguments as it would for C or C++. After this commit argument types
are included in the ptype output.
For example, before GDB prints:
(gdb) ptype fun1
type = integer(kind=4) ()
(gdb) ptype is_bigger
type = logical(kind=4) ()
and after GDB prints:
(gdb) ptype fun1
type = integer(kind=4) (integer(kind=4))
(gdb) ptype is_bigger
type = logical(kind=4) (integer(kind=4), integer(kind=4))

gdb/fortran: Print 'void' type in lower case
For a program compiled with gfortran the base type names are written
as lower cases in the DWARF, and so GDB will display them as lower
case. Additionally, in most places where GDB supplies its own type
names (for example all of the types defined in f-lang.c in
`build_fortran_types`), the type names are all lower case.
An exception to this is where GDB prints the void type for Fortran.
In this case GDB uses upper case.
I'm not aware of any reason why this type should merit special
attention, and it looks our of place when printing types, so this
commit changes from 'VOID' to 'void' to match all the other types.
gdb/ChangeLog:
* f-lang.c (build_fortran_types): Change name of void type to
lower case.
* f-typeprint.c (f_type_print_base): Print the name of the void
type, rather than a fixed string.
* f-valprint.c (f_decorations): Use lower case void string.
gdb/testsuite/ChangeLog:
* gdb.fortran/exprs.exp (test_convenience_variables): Expect lower
case void string.

gdb/fortran: better types for components of complex numbers
Currently when using $_creal and $_cimag to access the components of a
complex number the types of these components will have C type names
'float', 'double', etc. This is because the components of a complex
number are not given type names in DWARF, so GDB has to pick some
suitable names, and currently we always use the C names.
This commit changes the type names used based on the language, so for
Fortran we will now use the Fortran float types, and so will get the
Fortran float type names 'real', 'real*8', etc.

gdb/fortran: Introduce fortran-operator.def file
Future commits will add more Fortran specific expression operators.
In preparation for these new operators, this commit adds a new
fortran-operator.def file similar to how GDB already has
ada-operator.def.
I've moved UNOP_KIND the Fortran specific operator I introduced in
commit 4d00f5d8f6c4 into this file, and renamed it to make it clearer
that the operator is Fortran specific. I've then updated the Fortran
exp_descriptor table (exp_descriptor_f) to use entirely Fortran
specific functions that now handle UNOP_FORTRAN_KIND (the new name for
UNOP_KIND).
There should be no visible changes for standard users after this
commit, though for developers, the output when 'set debug expression
1' is now better, before:

gdb: Introduce 'print max-depth' feature
Introduce a new print setting max-depth which can be set with 'set
print max-depth DEPTH'. The default value of DEPTH is 20, but this
can also be set to unlimited.
When GDB is printing a value containing nested structures GDB will
stop descending at depth DEPTH. Here is a small example:
typedef struct s1 { int a; } s1;
typedef struct s2 { s1 b; } s2;
typedef struct s3 { s2 c; } s3;
typedef struct s4 { s3 d; } s4;
s4 var = { { { { 3 } } } };
The following table shows how various depth settings affect printing
of 'var':
| Depth Setting | Result of 'p var' |
|---------------+--------------------------------|
| Unlimited | $1 = {d = {c = {b = {a = 3}}}} |
| 4 | $1 = {d = {c = {b = {a = 3}}}} |
| 3 | $1 = {d = {c = {b = {...}}}} |
| 2 | $1 = {d = {c = {...}}} |
| 1 | $1 = {d = {...}} |
| 0 | $1 = {...} |
Only structures, unions, and arrays are replaced in this way, scalars
and strings are not replaced.
The replacement is counted from the level at which you print, not from
the top level of the structure. So, consider the above example and
this GDB session:
(gdb) set print max-depth 2
(gdb) p var
$1 = {d = {c = {...}}}
(gdb) p var.d
$2 = {c = {b = {...}}}
(gdb) p var.d.c
$3 = {b = {a = 3}}
Setting the max-depth to 2 doesn't prevent the user from exploring
deeper into 'var' by asking for specific sub-fields to be printed.
The motivation behind this feature is to try and give the user more
control over how much is printed when examining large, complex data
structures.
The default max-depth of 20 means that there is a change in GDB's
default behaviour. Someone printing a data structure with 20 levels
of nesting will now see '{...}' instead of their data, they would need
to adjust the max depth, or call print again naming a specific field
in order to dig deeper into their data structure. If this is
considered a problem then we could increase the default, or even make
the default unlimited.
This commit relies on the previous commit, which added a new field to
the language structure, this new field was a string that contained the
pattern that should be used when a structure/union/array is replaced
in the output, this allows languages to use a syntax that is more
appropriate, mostly this will be selecting the correct types of
bracket '(...)' or '{...}', both of which are currently in use.
This commit should have no impact on MI output, expressions are
printed through the MI using -var-create and then -var-list-children.
As each use of -var-list-children only ever displays a single level of
an expression then the max-depth setting will have no impact.
This commit also adds the max-depth mechanism to the scripting
language pretty printers following basically the same rules as for the
built in value printing.
One quirk is that when printing a value using the display hint 'map',
if the keys of the map are structs then GDB will hide the keys one
depth level after it hides the values, this ensures that GDB produces
output like this:
$1 = map_object = {[{key1}] = {...}, [{key2}] = {...}}
Instead of this less helpful output:
$1 = map_object = {[{...}] = {...}, [{...}] = {...}}
This is covered by the new tests in gdb.python/py-nested-maps.exp.

gdb: Introduce new language field la_is_string_type_p
This commit is preparation work for the next commit, and by itself
makes no user visible change to GDB. I've split this work into a
separate commit in order to make code review easier.
This commit adds a new field 'la_is_string_type_p' to the language
struct, this predicate will return true if a type is a string type for
the given language.
Some languages already have a "is this a string" predicate that I was
able to reuse, while for other languages I've had to add a new
predicate. In this case I took inspiration from the value printing
code for that language - what different conditions would result in
printing something as a string.
A default "is this a string" method has also been added that looks for
TYPE_CODE_STRING, this is the fallback I've used for a couple of
languages.
In this commit I add the new field and initialise it for each
language, however at this stage the new field is never used.

gdb/ada: Update some predicate functions to return bool
A later commit would like to make use of a pointer to the function
ada_is_string_type, however, this will require the function to return
a bool (so the signature matches).
As the ada_is_string_type is a predicate function, and its return
value is only ever used as either true or false, then this commit
updates the function to return a bool.
As a consequence ada_is_character_type needs to change too.
There should be no user visible changes after this commit.

[gdb/testsuite] Fix regexp in skip_opencl_tests

then this regexp in skip_opencl_tests fails to match:

so instead we hit the default clause after a 30 seconds timeout. With the

Have 'thread|frame apply' style their output.
'thread|frame apply CMD' launches CMD so that CMD output goes to a string_file.
This patch ensures that string_file for such CMD output contains
style escape sequences that 'thread|frame apply' will later on
output on the real terminal, so as to have CMD output properly styled.
The idea is to have the class ui_file having overridable methods
to indicate that the output to this ui_file should be done using
'terminal' behaviour such as styling.
Then these methods are overriden in string_file so that a specially
constructed string_file will get output with style escape sequences.
After this patch, the output of CMD by thread|frame apply CMD is styled
similarly as when CMD is launched directly.
Note that string_file (term_out true) could also support wrapping,
but this is not done (yet?).
Tested on debian/amd64.

Implement show | set may-call-functions [on|off]
Inferior function calls are powerful but might lead to undesired
results such as crashes when calling nested functions (frequently
used in particular in Ada).
This implements a GDB setting to disable calling inferior functions.
Note: the idea is that if/when the 'slash command' patch is pushed,
that this setting can be changed e.g. by using the shortcut /c.
This is version 2 of the patch. It handles all the received comments,
mostly replace 'can-call' by 'may-call', and avoid using
'inferior function call' in factor of 'calling function in the program'.

c++/24367: Infinite recursion of typedef substitution
This bug finds another usage where we end up segfaulting while
normalizing user input. inspect_type and replace_type recurse,
attempting to substitute the "real" symbol name for the typedef name.
However, since the both these names are the same, they keep calling
each other until the stack overflows.
A simple reproducer for it is given by
typedef struct foo foo;
int qux (foo *f) { return 0; }
(gdb) b qux(foo*)
Segmentation fault
inspect_type already contains some special handling to prevent a
similar situation from occurring with namespaces. I wonder, however,
whether we need be so pedantic about the exact nature of the substitution.
This patch implements this rather more aggressive assumption that these
substitutions should be avoided whenever the replacement symbol's name is
exactly the same as the one we're trying to substitute. [In the above
example, we're trying to substitute the tyepdef named "foo" with the symbol
named "foo" (a struct).]

Fix memory leak in exception code
PR gdb/24475 concerns a memory leak coming from gdb's exception
handling code.
The leak occurs because throw_exception_sjlj does not arrange to
destroy the exception object it is passed. However, because
gdb_exception has a destructor, it's undefined to longjmp in this
situation.
This patch fixes the problem by avoiding the need to run any
destructors in gdb_rl_callback_handler, by making the gdb_exception
"static".

Implement dump of mappings with ELF headers by gcore
This patch has a long story, but it all started back in 2015, with
commit df8411da087dc05481926f4c4a82deabc5bc3859 ("Implement support
for checking /proc/PID/coredump_filter"). The purpose of that commit
was to bring GDB's corefile generation closer to what the Linux kernel
does. However, back then, I did not implement the full support for
the dumping of memory mappings containing ELF headers (like mappings
of DSOs or executables). These mappings were being dumped most of
time, though, because the default value of /proc/PID/coredump_filter
is 0x33, which would cause anonymous private mappings (DSOs/executable
code mappings have this type) to be dumped. Well, until something
happened on binutils...
A while ago, I noticed something strange was happening with one of our
local testcases on Fedora GDB: it was failing due to some strange
build-id problem. On Fedora GDB, we (unfortunately) carry a bunch of
"local" patches, and some of these patches actually extend upstream's
build-id support in order to generate more useful information for the
user of a Fedora system (for example, when the user loads a corefile
into GDB, we detect whether the executable that generated that
corefile is present, and if it's not we issue a warning suggesting
that it should be installed, while also providing the build-id of the
executable). A while ago, Fedora GDB stopped printing those warnings.
I wanted to investigate this right away, and spent some time trying to
determine what was going on, but other things happened and I got
sidetracked. Meanwhile, the bug started to be noticed by some of our
users, and its priority started changing. Then, someone on IRC also
mentioned the problem, and when I tried helping him, I noticed he
wasn't running Fedora. Hm... So maybe the bug was *also* present
upstream.
After "some" time investigating, and with a lot of help from Keith and
others, I was finally able to determine that yes, the bug is also
present upstream, and that even though it started with a change in ld,
it is indeed a GDB issue.
So, as I said, the problem started with binutils, more specifically
after the following commit was pushed:
commit f6aec96dce1ddbd8961a3aa8a2925db2021719bb
Author: H.J. Lu <hjl.tools@gmail.com>

ld: Add --enable-separate-code
This commit makes ld use "-z separate-code" by default on x86-64
machines. What this means is that code pages and data pages are now
separated in the binary, which is confusing GDB when it tries to decide
what to dump.
BTW, Fedora 28 binutils doesn't have this code, which means that
Fedora 28 GDB doesn't have the problem. From Fedora 29 on, binutils
was rebased and incorporated the commit above, which started causing
Fedora GDB to fail.
Anyway, the first thing I tried was to pass "-z max-page-size" and
specify a bigger page size (I saw a patch that did this and was
proposed to Linux, so I thought it might help). Obviously, this
didn't work, because the real "problem" is that ld will always use
separate pages for code and data. So I decided to look into how GDB
dumped the pages, and that's where I found the real issue.
What happens is that, because of "-z separate-code", the first two pages
of the ELF binary are (from /proc/PID/smaps):

Notice how we have "Anonymous" data mapped into the page. This will be
important.
So, the way GDB decides which pages it should dump has been revamped
by my patch in 2015, and now it takes the contents of
/proc/PID/coredump_filter into account. The default value for Linux
is 0x33, which means:
Dump anonymous private, anonymous shared, ELF headers and HugeTLB
private pages.
Or:
filter_flags filterflags = (COREFILTER_ANON_PRIVATE
| COREFILTER_ANON_SHARED
| COREFILTER_ELF_HEADERS
| COREFILTER_HUGETLB_PRIVATE);
Now, it is important to keep in mind that GDB doesn't always have *all*
of the necessary information to exactly determine the type of a page, so
the whole algorithm is based on heuristics (you can take a look at
linux-tdep.c:dump_mapping_p and
linux-tdep.c:linux_find_memory_regions_full for more info).
Before the patch to make ld use "-z separate-code", the (single) page
containing data and code was being flagged as an anonymous (due to the
non-zero "Anonymous:" field) private (due to the "r-xp" permission),
which means that it was being dumped into the corefile. That's why it
was working fine.
Now, as you can imagine, when "-z separate-code" is used, the *data*
page (which is where the ELF notes are, including the build-id one) now
doesn't have any "Anonymous:" mapping, so the heuristic is flagging it
as file-backed private, which is *not* dumped by default.
The next question I had to answer was: how come a corefile generated by
the Linux kernel was correct? Well, the answer is that GDB, unlike
Linux, doesn't actually implement the COREFILTER_ELF_HEADERS support.
On Linux, even though the data page is also treated as a file-backed
private mapping, it is also checked to see if there are any ELF headers
in the page, and then, because we *do* have ELF headers there, it is
dumped.
So, after more time trying to think of ways to fix this, I was able to
implement an algorithm that reads the first few bytes of the memory
mapping being processed, and checks to see if the ELF magic code is
present. This is basically what Linux does as well, except that, if
it finds the ELF magic code, it just dumps one page to the corefile,
whereas GDB will dump the whole mapping. But I don't think that's a
big issue, to be honest.
It's also important to explain that we *only* perform the ELF magic
code check if:
- The algorithm has decided *not* to dump the mapping so far, and;
- The mapping is private, and;
- The mapping's offset is zero, and;
- The user has requested us to dump mappings with ELF headers.
IOW, we're not going to blindly check every mapping.
As for the testcase, I struggled even more trying to write it. Since
our build-id support on upstream GDB is not very extensive, it's not
really possible to determine whether a corefile contains build-id
information or not just by using GDB. So, after thinking a lot about
the problem, I decided to rely on an external tool, eu-unstrip, in
order to verify whether the dump was successful. I verified the test
here on my machine, and everything seems to work as expected (i.e., it
fails without the patch, and works with the patch applied). We are
working hard to upstream our "local" Fedora GDB patches, and we intend
to submit our build-id extension patches "soon", so hopefully we'll be
able to use GDB itself to perform this verification.
I built and regtested this on the BuildBot, and no problems were
found.

testsuite: Add option to capture gdbserver debug
Add both board option and environment variable which enables gdbserver
debug and sends it to the file gdbserver.debug, located in the output
directory for the current test. Document this.
Add support for the environment variable in the Makefile.
The testsuite can be run with gdbserver debug enabled in the following way:
make check GDBSERVER_DEBUG=all
Disable tspeed.exp when debugging to prevent the log file filling

LTO: Properly handle wrapper symbols in IR
When a wrapper symbol, __wrap_FOO, is defined in IR, its resolution
should be LDPR_PREVAILING_DEF, not PREVAILING_DEF_IRONLY, since LTO
doesn't know that __wrap_FOO provides definition of FOO. And resolution
of FOO should be LDPR_RESOLVED_IR since it is resolved by __wrap_FOO in
IR.

Detect invalid length field in debug frame FDE header.
GDB was failing to catch cases where a corrupt ELF or core file
contained an invalid length value in a Dwarf debug frame FDE header.
It was checking for buffer overflow but not cases where the length was
negative or caused pointer wrap-around.
In addition to the additional validity check, this patch cleans up the
multiple signed/unsigned conversions on the length field so that an
unsigned representation is used consistently throughout.
This patch fixes CVE-2017-9778 and PR gdb/21600.

[BFD, AArch64] Improve bti/pac plts.
This patch aims to improve the definitions of BTI and PAC based PLTs.
The following changes are made:
* PLT0 does not need PAC instructions since the PLTGOT[2] (and PLTGOT[1])
are readonly so they cannot be corrupted at runtime. Thus both PAC plt0
and BTI+PAC plt0 are removed and we can use basic plt0 and BTI plt0
instead, respectively.
* We can remove the extra padding nops when we add the new bti instructions.
BTI plt0 and BTI TLSDESC plt are updated.
* For better performance PLTn could be padded to 24bytes. Both BTI pltn and
PAC pltn are updated.

Speed up locview resolution with relaxable frags
Targets such as xtensa incur a much higher overhead to resolve
location view numbers than e.g. x86, because the expressions used to
compute view numbers cannot be resolved soon enough.
Each view number is computed by incrementing the previous view, if
they are both at the same address, or by resetting it to zero
otherwise. If PV is the previous view number, PL is its location, and
NL is the location of the next view, its number is computed by
evaluating NV = !(NL > PL) * (PV + 1).
set_or_check_view uses resolve_expression to decide whether portions
of this expression can be simplified to constants. The (NL > PL)
subexpression is one that can often be resolved to a constant,
breaking chains of view number computations at instructions of nonzero
length, but not after alignment that might be unnecessary.
Alas, when nearly every frag ends with a relaxable instruction,
frag_offset_fixed_p will correctly fail to determine a known offset
between two unresolved addresses in neighboring frags, so the
unresolved symbolic operation will be constructed and used in the
computation of most view numbers. This results in very deep
expressions.
As view numbers get referenced in location view lists, each operand in
the list goes through symbol_clone_if_forward_ref, which recurses on
every subexpression. If each view number were to be referenced, this
would exhibit O(n^2) behavior, where n is the depth of the view number
expressions, i.e., the length of view number sequences without an
early resolution that cuts the expression short.
This patch enables address compares used by view numbering to be
resolved even when exact offsets are not known, using new logic to
determine when the location either remained the same or changed for
sure, even with the possibility of relaxation. This enables most view
number expressions to be resolved with a small, reasonable depth.

Use better test for usable compiler in ld testsuite.
The ld testsuite includes numerous tests that depend on being able to
compile and link programs with the C compiler. Some of these tests
use [which $CC] to check for the presence of the compiler before
proceeding with the test, but run_ld_link_exec_tests and run_cc_link_tests
give ERRORs if compilation fails. Also, even if $CC is defined and present,
it may not be usable due to missing libraries, etc.
This patch adds a new procedure check_compiler_available that attempts
to build an empty program and caches the result. Uses of [which $CC]
are replaced with calls to this procedure, and run_ld_link_exec_tests
and run_cc_link_tests now also guard attempts to use $CC.

Use "pulongest" on aarch64-tdep.c:aarch64_gdbarch_init
While trying to build GDB on i686, I found the following error:

This happens because aarch64-tdep.c:aarch64_gdbarch_init prints a
"uint64_t" variable using "%ld". This patch fixes the build by using
"pulongest" instead. As explained in a similar fix (commit
495143533ad95369811391c6e3c6dadd69d7dd67), this should be safe because
if aarch64-tdep.c is included in the build, then ULONGEST must be a

Commit 4aa866af ("Fix AMD64 return value ABI in expression

resolve_symbol_value vs. .loc view resolution
In most cases we don't want expression symbols, such as that created
for an expression like "symbol + (1f - .)", resolved down to a
constant. Instead we'd like to leave the expression as "symbol +
constant" once the "1f - ." part has been resolved, and let the
backend decide whether "symbol" can be reduced further.
However, that doesn't work when trying to resolve .loc view symbols
early. We get expression symbols left as an O_symbol expression
pointing at an absolute symbol, and marked as sy_flags.sy_resolved.
That wouldn't really be a problem, but when one of those expression
symbols is used in further .loc view expressions, its value is taken
as zero.
This patch fixes the symbol value mistake, and stops creation of
O_symbol expression symbols pointing to absolute symbols. Either of
these fixes would cure the .loc view usage.
PR 24444
* symbols.c (resolve_symbol_value): When handling symbols
marked as sy_flags.resolved, return correct value for the

seg_left to test for undefined and common symbols. Don't
leave an O_symbol expression when X_add_symbol resolves to
the absolute_section. Init final_val later.

gdb/nds32: Use type_align instead of nds32_type_align
The general type_align method should be a suitable alternative to
nds32_type_align, so switch to use that.
The only change this will introduce is related to static fields in a
struct or union, the existing code doesn't take account of static
fields when computing the alignment for structs of unions, though this
is probably a bug - which would probably be exposed by the test case
gdb.cp/many-args.exp, though I don't have any way to test this target
right now.

* nds32-tdep.c (nds32_type_align): Delete.

gdb/arm: Use type_align instead of arm_type_align
Replaces use of arm_type_align with common type_align function.
Doing this fixes a bug in arm_type_align where static fields are
considered as part of the alignment calculation of a struct, which
results in arguments passed on the stack being misaligned, this bug
was causing a failure in gdb.cp/many-args.exp.
Part of the old arm_type_align is retained and used as the gdbarch
type align callback in order to correctly align vectors.

* arm-tdep.c (arm_type_align): Only handle vector override case.
(arm_push_dummy_call): Use type_align.

[gdb/testsuite] Fix gdb.btrace/reconnect.exp with native-gdbserver
When running gdb.btrace/reconnect.exp with native-gdbserver, we run into:

due to the fact that we're trying to match:

[gdb/contrib] Remove superfluous .alt file after dwz invocation in cc-with-tweaks.sh
The -m option of cc-with-tweaks.sh sets want_multi to true, invoking dwz like
this:
...
elif [ "$want_multi" = true ]; then
cp $output_file ${output_file}.alt
$DWZ -m ${output_file}.dwz "$output_file" ${output_file}.alt \
> /dev/null 2>&1
fi
...
The problem that is being solved here, is that we want to test dwz in
multifile mode, which requires more than one input file, while we only have
(at the scope of cc-with-tweaks.sh) one executable. We handle this by copying
the executable and offering this as a second input (and using a copy has the
additional benefit that it maximally enables dwz transformation).
However, after the dwz invocation, the copy is no longer used, and the
presence of the file actually causes a test regression:
...
FAIL: gdb.base/jit-so.exp: test jit-reader-load filename completion
...
Fix this by removing the superflous copy after dwz invocation.
Tested on x86_64-linux.

solib-svr4: Pass down svr4_info as much as possible
While reviewing
https://sourceware.org/ml/gdb-patches/2019-04/msg00141.html
I noticed that we relied heavily on global state through the
get_svr4_info function, which uses current_program_space. I thought we
could improve this (make things more explicit and easier to follow) by
- Making get_svr4_info accept a program_space parameter, making it
return the SVR4 info for that program space.
- Passing down the svr4_info object from callers as much as possible.
This means looking up the svr4_info for the appropriate program space at
the entry points of the solib-svr4.c file and passing it down. For now,
these entry points (most of them are "methods" of svr4_so_ops) rely on
current_program_space, but we can later try to change the target_so_ops
interface to pass down the program space.
gdb/ChangeLog:
* solib-svr4.c (get_svr4_info): Add pspace parameter.
(svr4_keep_data_in_core): Pass current_program_space to get_svr4_info.

(svr4_fetch_objfile_link_map): Pass objfile->pspace to

(svr4_in_dynsym_resolve_code): Pass current_program_space to
get_svr4_info.
(probes_table_htab_remove_objfile_probes): Pass objfile->pspace
to get_svr4_info.

Fix "nosharedlibrary + continue + shared lib event" crash
On systems that use the probes-based solib interface, GDB misbehaves
if you run the "nosharelibrary" command, continue execution, and then
the program hits the shared library event breakpoint. On my system it
aborts like this:
(gdb) nosharedlibrary
(gdb) c
Continuing.
pure virtual method called
terminate called without an active exception
Aborted (core dumped)
Though it's really undefined behavior territory, caused by deferencing
a dangling solib event probe pointer.
I've observed this by running "nosharedlibrary" when stopped at the
entry point, but it should happen at any other point, if the program
does a dlopen/dlclose after.
The fix is to discard an objfile's probes from the svr4 probes table
when an objfile is about to be released.
New test included, works with both native and gdbserver testing.
Valgrind log:
(gdb) starti
(gdb) nosharedlibrary
(gdb) c
Continuing.

Note, this little bit in the patch is just a cleanup that I noticed:
- lookup.prob = prob;
lookup.address = address;
That line isn't necessary because hashing/comparison only looks at the
address.

Fix GDB crash when registers cannot be modified.
This crash was detected when using GDB with the valgrind gdbserver.
To reproduce:
valgrind sleep 10000
In another window:
gdb
target remote | vgdb
p printf("make sleep print something\n")
=>
terminate called after throwing an instance of 'gdb_exception_error'
Aborted
The problem is that the valgrind gdbserver does not allow to change
registers when the inferior is blocked in a system call.
GDB then raises an exception. The exception causes the destructor
of
typedef std::unique_ptr<infcall_suspend_state, infcall_suspend_state_deleter>
infcall_suspend_state_up;
to be called. This destructor itself tries to restore the value of
the registers, and fails similarly. We must catch the exception in
the destructor to avoid crashing GDB.
If the destructor encounters a problem, no warning is produced if
there is an uncaught exception, as in this case, the user will already
be informed of a problem via this exception.
With this change, no crash anymore, and all the valgrind 3.15 tests
pass succesfully.

Print non-Ada unions without crashing
ada-lang.c is a bit too eager trying to decode unions in the Ada style
-- looking for discriminants and such. This causes crashes when
printing a non-Ada union in Ada mode, something that can easily happen
when printing a value from history or certain registers on AArch64.
This patch fixes the bug by changing ada-lang.c to only apply special
Ada treatment to types coming from an Ada CU. This in turn required a
couple of surprising changes.
First, some of the Ada code was already using HAVE_GNAT_AUX_INFO to
decide whether a type had already been fixed -- such types had
INIT_CPLUS_SPECIFIC called on them. This patch changes these spots to
use the "none" identifier instead.
This then required changing value_rtti_type to avoid changing the
language-specific object attached to an Ada type, which seems like a
good change regardless.
Tested on x86-64 Fedora 29.

[gdb/testsuite] Fix gdb.base/break-probes.exp with native-gdbserver
When running break-probes.exp with native-gdbserver, we run into:
...
FAIL: gdb.base/break-probes.exp: run til our library loads (the program exited)
FAIL: gdb.base/break-probes.exp: call (int) foo(23)
...
due to the fact that we're trying to match:
...
Inferior loaded /data/gdb_versions/devel/build/gdb/testsuite/outputs/gdb.base\
/break-probes/break-probes-solib.so
...
using pattern:
...
Inferior loaded $sysroot$binfile_lib
...
which expands into:
...
Inferior loaded //data/gdb_versions/devel/build/gdb/testsuite/outputs/gdb.base\
/break-probes/break-probes-solib.so
...
Fix by setting sysroot to "" in local-board.exp.
Tested on x86_64-linux with native-gdbserver.

[gdb] Handle vfork in thread with follow-fork-mode child
When debugging any of the testcases added by this commit, which do a
vfork in a thread with "set follow-fork-mode child" + "set
detach-on-fork on", we run into this assertion:
...
src/gdb/nat/x86-linux-dregs.c:146: internal-error: \
void x86_linux_update_debug_registers(lwp_info*): \
Assertion `lwp_is_stopped (lwp)' failed.
...
The assert is caused by the following: the vfork-child exit or exec
event is handled by handle_vfork_child_exec_or_exit, which calls
target_detach to detach from the vfork parent. During target_detach
we call linux_nat_target::detach, which:
#1 - stops all the threads
#2 - waits for all the threads to be stopped
#3 - detaches all the threads
However, during the second step we run into this code in
stop_wait_callback:
...
/* If this is a vfork parent, bail out, it is not going to report
any SIGSTOP until the vfork is done with. */
if (inf->vfork_child != NULL)
return 0;
...
and we don't wait for the threads to be stopped, which results in this
assert in x86_linux_update_debug_registers triggering during the third
step:
...
gdb_assert (lwp_is_stopped (lwp));
...
The fix is to reset the vfork parent's vfork_child field before
calling target_detach in handle_vfork_child_exec_or_exit. There's
already similar code for the other paths handled by
handle_vfork_child_exec_or_exit, so this commit refactors the code a
bit so that all paths share the same code.
The new tests cover both a vfork child exiting, and a vfork child
execing, since both cases would trigger the assertion.
The new testcases also exercise following the vfork children with "set
detach-on-fork off", since it doesn't seem to be tested anywhere.
Tested on x86_64-linux, using native and native-gdbserver.

Avoid crash in dwarf2_init_complex_target_type
After commit 35add35 ("gdb: Fix failure in gdb.base/complex-parts.exp

nullptr. This patch avoids the problem by checking for this case.

floating point type.

gdbserver: Move remote_debug to a single place
A comment in debug.h (written in 2014) states: "We declare debug format
variables here, and debug_threads but no other debug content variables
(e.g., not remote_debug) because while this file is not currently used by
IPA it may be some day, and IPA may have its own set of debug content
variables".
This has resulted in remote_debug being declared in many .c/.h files
throughout gdbserver.
It would be much simplier to define it one place. The most logical place to
define it is in debug.h, surrounded by #define guards. If IPA is changed,
then at that point the variable can be moved elsewhere.

gdb/riscv: Allow breakpoints to be created at invalid addresses
Some testsuite cases (gdb.cp/nsalias.exp for example) construct dwarf2
debug info for fake functions to test that this debug info is handled
correctly.
We currently get an error trying to read from an invalid address while
creating breakpoints for these fake functions.
Other targets allow creating breakpoints on invalid addresses, and
only error when GDB actually tries to insert the breakpoints.
In order to make RISC-V behave in the same way as other targets, this
commit makes the failure to read memory during breakpoint creation
non-fatal, we then expect to see a failure when GDB tries to insert
the breakpoint, just like other targets.
Tested with a riscv64-linux native testsuite run.
gdb/ChangeLog:
* riscv-tdep.c (riscv_breakpoint_kind_from_pc): Hanndle case where
code read might fail, assume 4-byte breakpoint in that case.

Fix AMD64 return value ABI in expression evaluation
The AMD64 System V ABI specifies that when a function has a return type
classified as MEMORY, the caller provides space for the value and passes
the address to this space as the first argument to the function (before
even the "this" pointer). The classification of MEMORY is applied to
struct that are sufficiently large, or ones with unaligned fields.
The expression evaluator uses call_function_by_hand to call functions,
and the hand-built frame has to push arguments in a way that matches the
ABI of the called function. call_function_by_hand supports ABI-based
struct returns, based on the value of gdbarch_return_value, however on
AMD64 the implementation of the classifier incorrectly assumed that all
non-POD types (implemented as "all types with a base class") should be
classified as MEMORY and use the struct return.
This ABI mismatch resulted in issues when calling a function that returns
a class of size <16 bytes which has a base class, including issues such
as the "this" pointer being incorrect (as it was passed as the second
argument rather than the first).
This is now fixed by checking for field alignment rather than POD-ness,
and a testsuite is added to test expression evaluation for AMD64.

rather than a hand-rolled POD check when checking for forced MEMORY
classification.

AArch64 SVE: Support changing vector lengths for ptrace
When writing registers to the kernel, check if regcache VG has been changed. If
so then update the thread's vector length, then write back the registers.

The regcache registers should already be of the correct length.
Remove all the checks that error if the vector length has changed.

[binutils, ARM, 16/16] Add support to VLDR and VSTR of system registers
GNU as' Arm backend assumes each mnemonic has a single entry in the instruction table but VLDR (system register) and VSTR (system register) are different instructions than VLDR and VSTR. It is thus necessary to add some form of demultiplexing in the parser. It starts by creating a new operand type OP_VLDR which indicate that the operand is either the existing OP_RVSD operand or a system register. The function parse_operands () then tries these two cases in order, calling the new parse_sys_vldr_vstr for the second case.
Since the encoding function is specified in the instruction table entry, it also need to have some sort of demultiplexing. This is done in do_vldr_vstr which either calls the existing do_neon_ldr_str () or calls the new do_t_vldr_vstr_sysreg ().
A new internal relocation is needed as well since the offset has a shorter range than in other Thumb coprocessor instructions. Disassembly also requires special care since VSTR (system register) reuse the STC encoding with the coprocessor number 15. Armv8.1-M Mainline ARM manual states that coprocessor 8, 14 and 15 are reserved for floating-point and MVE instructions a feature bit check is added if the coprocessor number is one of this value and we are trying to match a coprocessor instruction (eg. STC) to forbid the match.

[binutils, ARM, 15/16] Add support for VSCCLRM
Like for CLRM, this patch aims to share as much logic with the similar looking VLDM/VSTM. This is achieved by adding 2 new enumerator values in enum reg_list_els for the single-precision and double-precision variants of VSCCLRM and extending parse_vfp_reg_list () to deal with these types.
These behave like the existing REGLIST_VFP_S and REGLIST_VFP_D types with extra logic to expect VPR as the last element in the register list.
The function is algo augmented with a new partial_match parameter to indicate if any register other than VPR had already been parsed in the register list so as to not try parsing the second variant if that's the case and return the right error message.
The rest of the patch is the usual encoding function, new disassembler table entries and format specifier and parsing, encoding and disassembling tests.
It is worth mentioning that the new entry in the disassembler table was added in the coprocessor-related table despite VSCCLRM always being available even in FPU-less configurations. The main reason for this is that VSCCLRM also match VLDMIA entry and must thus be tried first but coprocessor entries are tried before T32 entries. It also makes sense because it is in the same encoding space as coprocessor and VFP instructions and is thus the natural place for someone to look for this instruction.
Note: Both variants of VSCCLRM support D16-D31 registers but Armv8.1-M Mainline overall does not. I have thus decided not to implement support for these registers in order to keep the code simpler. It can always be added later if needed.

[opcodes, ARM, 14/16] Add mode availability to coprocessor table entries
The coprocessor_opcodes table is used both to share commonalities in coprocessor-related instructions and to avoid duplication between Arm and Thumb mode. However, some instructions do have differences between Arm and Thumb. For instance, vldmia allows PC as base register in Arm mode but not in Thumb mode.
In that very case the distinction becomes necessary because the encoding with PC as base register is used in Thumb mode to denote a VSCCLRM. It is thus necessary to distinguish what is Arm or Thumb only from what is shared. This patch adds an extra field to the coprocessor_opcodes table entries to indicate what mode is a given instruction available in. The print_insn_coprocessor then uses that field to determine if an entry that matched the mark and value checked should be allowed to match or not given the current mode.
ChangeLog entry is as follows:

[binutils, ARM, 13/16] Add support for CLRM
Given the similarity between LDM/STM and CLRM register lists, most of the changes in this patch aim at sharing code between those two sets of instruction. Sharing is achieved both in parsing and encoding of those instructions.
In terms of parsing, parse_reg_list () is extended to take a type that describe what type of instruction is being parsed. The reg_list_els used for parse_vfp_reg_list () is reused for the type and that function is added an assert for the new REGLIST_CLRM and REGLIST_RN enumerators.
parse_reg_list () is then taught to accept APSR and reject SP and PC when parsing for a CLRM instruction. At last, caller of parse_reg_list () is updated accordingly and logic is added for the new OP_CLRMLST operand.
Encoding-wise, encode_thumb2_ldmstm () is reused to encode the variable bits of CLRM and is thus renamed encode_thumb2_multi (). A new do_io parameter is added to distinguish between LDM/STM and CLRM which guard all the LDM/STM specific code of the function.
Finally objdump is told how to disassemble CLRM, again reusing the logic to print the LDM/STM register list (format specifier 'm'). Tests are also added in the form of negative tests to check parsing and encoding/disassembling tests.

[binutils, ARM, 5/16] BF insns infrastructure with new global reloc R_ARM_THM_BF16
This patch is part of a series of patches to add support for Armv8.1-M Mainline instructions to binutils.
This adds infrastructure for the BF instructions which is one of the first instructions in Arm that have more than one relocations in them.
This is the third infrastructure patch that adds a new relocation R_ARM_THM_BF16.
The inconsistency between external R_ARM_THM_BF16 and internal
BFD_RELOC_ARM_THUMB_BF17 is because internally we count the static bit-0 of the immediate and we don't externally.

[binutils, ARM, 4/16] BF insns infrastructure with array of relocs in struct arm_it
This patch is part of a series of patches to add support for ARMv8.1-M Mainline
instructions to binutils.
This adds infrastructure for the Branch Future instructions (BF, BFX, BFL,
BFLX, BFCSEL).
These are the first instructions in ARM that have more than one relocations in
them. Their external relocations can be found in the 'ELF for the Arm
Architecture - ABI 2019Q1' document on developer.arm.com
This is the second infrastructure patch that adds support to allow up to
3 relocations in an instruction. This is done by changing the reloc member of
struct arm_it to an array instead (relocs[3]). All the previous occurrences of
reloc can now to referring to relocs[0].

[binutils, ARM, 3/16] BF insns infrastructure with new bfd_reloc_code_real for fallback branch
This patch is part of a series of patches to add support for Armv8.1-M Mainline
instructions to binutils.
This adds infrastructure for the Branch Future instructions (BF, BFX, BFL, BFLX,
BFCSEL). These are the first instructions in ARM that have more than one
relocations in them.
This is the first infrastructure patch that adds a new bfd_reloc_code_real enum
for the fallback branch offset.
This is common for all such instructions and needs to be resolvable by the
assembler.

[binutils, ARM, 1/16] Add support for Armv8.1-M Mainline CLI
The patch is straightforward, it does the following:
- support the new Tag_CPU_arch build attribute value, ie.:
+ declare the new value
+ update all the asserts forcing logic to be reviewed for new
architectures
+ create a corresponding bfd_mach_arm_8_1M_MAIN enumerator in bfd and
add mapping from Tag_CPU_arch to it
+ teach readelf about new Tag_CPU_arch value
- declare armv8.1-m.main as a supported architecture value
- define Armv8.1-M Mainline in terms of feature bits available
- tell objdump mapping from bfd_mach_arm_8_1M_MAIN enumerator to feature
bits available
- update architecture-specific logic in gas and bfd guarded by the
asserts mentioned above.
- tests for all the above

sim: Use host not target byte order for merging and splitting values
When using writes to memory through a struct to merge and extract
multi-word value, it is the endianness of the host, not the target
that affects which order the component words need to be written into
the structure.
Of the 5 functions adjusted here 4 of them are unused. The 5th,
JOINSIDF will soon be used by the or1k target.
For or1k, simulated on x86-64, this change fixes this function so that
the correct bytes are now returned.

Automatic makefile dependencies for generated ld/e*.c
This patch modifies genscripts.sh to emit dependency info along with
the generated emulation e*.c files. This is done by a new source_sh

included by the Makefile.

gdb: Fix failure in gdb.base/complex-parts.exp for x86-32
The x86-32 ABI specifies 96-bit long double, this was causing a
failure on the test gdb.base/complex-parts.exp.
The problem is that GDB tries to find a builtin floating point type of
the correct size in order to reuse the name of that type as the name
for the components of the complex type being built.
Previously GDB was only aware of floating point types sized 32, 64, or
128 bits. This patch teaches GDB how to handle 96 bit floating point
type.
gdb/ChangeLog:
* dwarf2read.c (dwarf2_init_complex_target_type): Handle complex
target types of size 96-bits, add some additional comments, and
check that the builtin type we found was the correct size.

gdb: Remove LANG_MAGIC
The language_defn structure has an la_magic field, this used to be
used as a basic check that the language_defn structure had the
expected layout - at least the end of the structure was where we
expected it to be.
This feature only really makes sense if we imagine GDB dynamically
loading language support from dynamic libraries, where a version
mismatch might cause problems.
However, in current GDB language support is statically built into GDB,
and since this commit:

Date: Thu Jul 20 18:28:01 2017 +0100
Make language_def O(1)
the existing (if pointless) check of the la_magic field was removed.
There now appears to be no use of the la_magic field, and I propose
that we delete it.
There should be no user visible changes after this commit.

gdb/riscv: Handle empty C++ structs during argument passing
This commit resolves a large number of failures in the test script
gdb.base/infcall-nested-structs.exp which were caused by GDB (for
RISC-V) incorrectly handling empty C++ structures when preparing
arguments for a dummy call, or collecting a return value.
The issue is further complicated in that there was a bug in GCC, such
that in some cases GCC would generate incorrect code when passing a
small structure that contained empty sub-structures. This was fixed
in GCC trunk on 5-March-2019, so in order to see the best results with
this patch you'll need a recent version of GCC.
Anything that used to work should continue to work after this patch,
regardless of GCC version being used.
The fix in this commit is that GDB now pays more attention to the
offset of fields within a structure when preparing arguments as in C++
an empty structure has a non-zero size, this is an example:
struct s1 { struct s2 { } empty; int f; };
We previously assumed that 'f' was at offset 0 inside type 's1',
however this is not the case in C++ as 's2' has size 1, and with
alignment 'f' is likely at some even bigger offset inside 's1'.
gdb/ChangeLog:
* riscv-tdep.c (riscv_call_arg_complex_float): Fix offset of first
component to 0.
(riscv_struct_info::riscv_struct_info): Initialise m_offsets
member.
(riscv_struct_info::analyse): New implementation using new
analyse_inner member function.
(riscv_struct_info::field_offset): New member function.
(riscv_struct_info::m_offsets): New member variable.
(riscv_struct_info::analyse_inner): New private member function,
takes the old implementation of riscv_struct_info::analyse but
extended to track field offsets.
(riscv_call_arg_struct): Update the struct folding special cases
to handle cases where empty C++ structs, which are non-zero
length, are found.
(riscv_arg_location): Initialise the length of each location, a
non-zero length now indicates the location is in use.
(riscv_push_dummy_call): Allow for the first location having a
non-zero offset when setting up arguments.
(riscv_return_value): Likewise, but for return values.

[gdb/testsuite] Add cc-with-dwz.exp and cc-with-dwz-m.exp
We can use CC_WITH_TWEAKS_FLAGS when cd-ing into the gdb build subdir and
invoking make check:
...
$ cd $objdir/gdb
$ make check \
RUNTESTFLAGS='--target_board=cc-with-tweaks' \
CC_WITH_TWEAKS_FLAGS='-z'
...
But when cd-ing into the top-level build dir and invoking make check-gdb
instead:
...
$ cd $objdir
$ make check-gdb \
RUNTESTFLAGS='--target_board=cc-with-tweaks' \
CC_WITH_TWEAKS_FLAGS='-z'
...
using CC_WITH_TWEAKS_FLAGS has no effect, because CC_WITH_TWEAKS_FLAGS is not
passed down from the top level Makefile.
Add cc-with-dwz.exp and cc-with-dwz-m.exp, that don't require
CC_WITH_TWEAKS_FLAGS to be set in the make invocation, allowing us to run these
test configurations from the toplevel build dir:
...

AArch64: When DF_BIND_NOW don't use TLSDESC GOT value.
When using DF_BIND_NOW on AArch64 we don't reserve the GOT slot for a TLSDESC,
but we still emitted DT_TLSDESC_GOT and DT_TLSDESC_PLT. This caused random
memory corruption as the "special" value of (bfd_vma)-1 would be set for
dt_tlsdesc_got.
Since we don't have a value of dt_tlsdesc_got I also don't emit DT_TLSDESC_PLT
now becuase it would point to an incomplete PLT. To be able to write the PLT
entry DT_TLSDESC_GOT is needed and since we don't have one we can't write the
PLT entry either.
It is my understanding that GLIBC doesn't need these two entries when not lazy
loading. Conversely AArch32 does not reserve neither the GOT not the PLT slot
when doing DF_BIND_NOW.
AArch32 does not need these checks because these values are initialized to 0
and so the if (...) checks don't pass, but on AArch64 these are initialized
to (bfd_vma)-1 and thus we need some extra checks.

[BINUTILS, AArch64, 2/2] Update Store Allocation Tag instructions
This patch updates the Store allocation tags instructions in
Armv8.5-A Memory Tagging Extension. This is part of the changes
that have been introduced recently in the 00bet10 release
All of these instructions have an updated register operand (Xt -> <Xt|SP>)
- STG <Xt|SP>, [<Xn|SP>, #<simm>]
- STG <Xt|SP>, [<Xn|SP>, #<simm>]!
- STG <Xt|SP>, [<Xn|SP>], #<simm>

- STZ2G <Xt|SP>, [<Xn|SP>, #<simm>]!
- STZ2G <Xt|SP>, [<Xn|SP>], #<simm>
In order to accept <Rt|SP> a new operand type Rt_SP is introduced which has
the same field as FLD_Rt but follows other semantics of Rn_SP.

Fix amd64->i386 linux syscall restart problem
This commit fixes some failures in gdb.base/interrupt.exp
when debugging a 32-bit i386 linux inferior from an amd64 host.
When running the following test...
make check RUNTESTFLAGS="--target_board unix/-m32 interrupt.exp"
... without this commit, I see the following output:
FAIL: gdb.base/interrupt.exp: continue (the program exited)
FAIL: gdb.base/interrupt.exp: echo data
FAIL: gdb.base/interrupt.exp: Send Control-C, second time
FAIL: gdb.base/interrupt.exp: signal SIGINT (the program is no longer running)
ERROR: Undefined command "".
ERROR: GDB process no longer exists
=== gdb Summary ===
When the test is run with this commit in place, we see 12 passes
instead. This is the desired behavior.
Analysis:
On Linux, when a syscall is interrupted by a signal, the syscall
may return -ERESTARTSYS when a signal occurs. Doing so indicates that
the syscall is restartable. Then, depending on settings associated
with the signal handler, and after the signal handler is called, the
kernel can then either return -EINTR or can cause the syscall to be
restarted. In this discussion, we are concerned with the latter
case.
On i386, the kernel returns this status via the EAX register.
When debugging a 32-bit (i386) process from a 64-bit (amd64)
GDB, the debugger fetches 64-bit registers even though the
process being debugged is 32-bit. Since we're debugging a 32-bit
target, only 32 bits are being saved in the register cache.
Now, ideally, GDB would save all 64-bits in the regcache and
then would be able to restore those same values when it comes
time to continue the target. I've looked into doing this, but
it's not easy and I don't see many benefits to doing so. One
benefit, however, would be that EAX would appear as a negative
value for doing syscall restarts.
At the moment, GDB is setting the high 32 bits of RAX (and other
registers too) to 0. So, when GDB restores EAX just prior to
a syscall restart, the high 32 bits of RAX are zeroed, thus making
it look like a positive value. For this particular purpose, we
need to sign extend EAX so that RAX will appear as a negative
value when EAX is set to -ERESTARTSYS. This in turn will cause
the signal handling code in the kernel to recognize -ERESTARTSYS
which will in turn cause the syscall to be restarted.
This commit is based on work by Jan Kratochvil from 2009:
https://sourceware.org/ml/gdb-patches/2009-11/msg00592.html
Jan's patch had the sign extension code in amd64-nat.c. Several
other native targets make use of this code, so it seemed better
to move the sign extension code to a linux specific file. I
also added similar code to gdbserver.
Another approach is to fix the problem in the kernel. Hui Zhu
tried to get a fix into the kernel back in 2014, but it was not
accepted. Discussion regarding this approach may be found here:
https://lore.kernel.org/patchwork/patch/457841/
Even if a fix were to be put into the kernel, we'd still need
some kind of fix in GDB in order to support older kernels.
Finally, I'll note that Fedora has been carrying a similar patch for
at least nine years. Other distributions, including RHEL and CentOS
have picked up this change and have been using it too.

Disable R_X86_64_PLT32 generation as branch marker on Solaris/x86
The fix H.J. implemented for PR gas/22791 in the thread starting at
[PATCH] x86-64: Treat PC32 relocation with branch as PLT32
https://sourceware.org/ml/binutils/2018-02/msg00065.html
is causing problems on Solaris/x86. The native linker is strongly
preferred there, and there's no intention of implementing the linker
optimization he plans there. Besides, the kernel runtime linker,
otherwise has no need to deal with that reloc at all, and instead of
adding (possibly even more) workarounds with no benefit, it seems
appropriate to disable the R_X86_64_PLT32 generation as branch marker on
Solaris/x86 in the first place.
The patch itself is trivial, the only complication is adapting the
testsuite. Since I've found no way to have conditional sections in the
.d files, I've instead used the solution already found elsewhere of
having separate .d files for the affected tests in an i386/solaris
subdirectory and skipping the original ones.
Tested on amd64-pc-solaris2.11 and x86_64-pc-linux-gnu without
regressions.

Fix Rust lexer buglet
PR rust/24414 points out that the Rust lexer uses strtoul when lexing
an integer, and that this can give the wrong results in some
situations.
This patch changes it to use strtoulst, like most of the rest of gdb.
It also adds a self test.
Tested on x86-64 Fedora 29 using an i686 build.

Use find_thread_in_random in select_event_lwp
I noticed that find_thread_in_random duplicates the code in
find_thread_in_random, so this patch changes the latter to use the
former.
There are two other spots in gdb that do this, but to unify all of
them would require switching some code from using the "iterate over"
idiom to using iterators.
Another possible improvement is that find_thread_in_random could be
made single-pass using reservoir sampling.
Tested by the buildbot.

Use -qualified flag when setting temporary breakpoint in start command
When using the "start" command, GDB puts a temporary breakpoint on the
"main" symbol (we literally invoke the tbreak command). However, since
it does wild matching by default, it also puts a breakpoint on any C++
method or "main" function in a namespace. For example, when debugging
GDB, it creates a total of 24 locations:
(gdb) start
Temporary breakpoint 1 at 0x198c1e9: main. (24 locations)
as there are a bunch of methods called main in the selftests, such as
selftests::string_view::capacity_1::main()
If such method was called in the constructor of a global object, or a
function marked with the attribute "constructor", then we would stop at
the wrong place. Also, this causes a few extra symtabs (those that
contain the "wrong" mains) to be expanded for nothing.
The dummiest, most straightforward solution is to add -qualified when
invoking tbreak. With this patch, "start" creates a single-location
breakpoint, as expected.
I copied the start.exp test to start-cpp.exp and made it use a C++ test
file, which contains two main functions. The new test verifies that the
output of "start" is the output we get when we set a single-location
breakpoint.

* infcmd.c (run_command_1): Pass -qualified to tbreak when usind
the "start" command.

Rename python function thread_from_thread_handle to thread_from_handle
This renaming was done to stay consistent with the naming of the new
gdb.InferiorThread.handle method. I had initially named it "thread_handle"
but Tom Tromey suggested just "handle".
The old name (thread_from_thread_handle) still works, but is marked as
deprecated in comments in the code as well as in the documentation.
I have some code which uses these functions. I very much like the
brevity of the new names.

Support buffer objects as handles in Inferior.thread_from_thread_handle()
InferiorThread.handle() returns a python bytes object. We'd like to
be able to pass the output of this function, a thread handle, to
Inferior.thread_from_thread_handle(). Up to now,
thread_from_thread_handle() expects to receive a gdb.Value input.
This commit adds support to also allow a python buffer object to be
passed as the handle.
infpy_thread_from_thread_handle() calls find_thread_by_handle() which
has the obvious functionality. It used to pass the thread handle via
a struct value pointer. I've revised this interface to instead pass a
gdb::array_view<const gdb_byte> object. (Thanks to Tom Tromey for
suggesting this data structure over an earlier version which passed a
gdb_byte pointer and length.)

* gdbthread.h (find_thread_by_handle): Revise declaration.
* thread.c (find_thread_by_handle): Likewise. Adjust
implementation too.
* python/py-inferior.c (infpy_thread_from_thread_handle): Add

Some gdb_exception{,error,quit} tweaks
- Explicitly include <string> for std::string.
- Use std::make_shared to construct gdb_exception::message instead of
operator new, avoiding one heap allocation (2 instead of 3). Add
'const char *fmt, va_list ap' parameters to
gdb_exception{,error,quit}'s ctors, and do the std::make_shared in
the gdb_exception ctor.
- gdb_exception_error's constructor does not need to have an 'enum
return_reason' parameter, since it is always RETURN_ERROR, by
definition.
- Similarly, gdb_exception_quit's contructor does not need to have
'enum return_reason'/'enum errors' parameters.
- In the gdb_exception_{quit,_error} ctors that take a gdb_exception
as argument, assert that they're being passed a gdb_exception object
of the right 'reason'.

Replace throw_exception with throw in some cases
This replaces throw_exception with "throw;" when possible. This was
written by script. The rule that is followed is that uses of the
form:
catch (... &name)
{
...
throw_exception (name);
}
... can be rewritten. This should always be safe, because exceptions
are caught by const reference, and therefore can't be modified in the

The intermediate layer of gdb_exception_RETURN_MASK_ALL did not seem
needed, so this patch removes it entirely.

Make exceptions use std::string and be self-managing
This changes the exception's "message" member to be a shared_ptr
wrapping a std::string. This allows removing the stack of exception
messages, because now exceptions will self-destruct when needed. This
also adds a noexcept copy constructor and operator= to gdb_exception,
plus a "what" method.

Simplify exception handling
Now that cleanups have been removed, TRY/CATCH can't be SJLJ-based any
more. This patch simplifies the exception handling code, by removing
the non-working variants.
Note that the "pure" C++ exception handling code is removed as well; I
think the route forward must be to change exceptions to be
self-destructing, so that try_scope_depth can simply be removed.
Some longjmp-based code remains, as it is needed to throw an exception
through readline.

Make "all" depend on "info"
I've broken "make info" a couple of times now, because I sometimes
forget to run "make info" after modifying a Texinfo file.
I don't know why gdb's "make all" doesn't build the info pages. I
suspect this was some Cygnus-local oddity back in the day.
This patch changes doc/Makefile.in so that the info pages are built by
"make all". As a point of reference, Automake has essentially always
worked this way. According to the Automake manual (I didn't
double-check) this is required by the GNU coding standards.
The first time I sent this patch, I mentioned that I wanted to look
into some existing bugs in bugzilla about missing "makeinfo".
However, today I tried and I discovered that BFD requires makeinfo,
and builds its info file as part of "all". So, I think this change
doesn't worsen the situation for users in any way, and can simply go
in.

Andreas Schwab and John Baldwin pointed out some bugs in the header
sorting patch; and I noticed that the output was not correct when
limited to a subset of files (a bug in my script).
So, I'm reverting the patch. I may try again after fixing the issues

commit 0570503dd31bc20294e228339fcbdd39b19608cc

Use linux_get_auxv to get AT_PHDR in the PPC stub
This patch fixes a build error due to a call to ppc_get_auxv that was
left over after linux_get_hwcap and linux_get_hwcap2 were introduced
in:
974c89e0882ddb03e294eca76a9e3d3bef90eacf gdbserver: Add
linux_get_hwcap
Because the missing call fetched AT_PHDR and not AT_HWCAP,
linux_get_auxv is now visible.
This use also required ppc_get_auxv to return a status variable
indicating that the AT_PHDR entry was not found separately from the
actual value of of the auxv entry. Therefore, the new linux_get_auxv
function is changed to return a status variable and write the entry
value to a pointer passed as an argument.
Note that linux_get_hwcap and linux_get_hwcap2 still use the return
value as both an indicator of that the entry wasn't found and as the
actual value of the entry.
gdb/gdbserver/ChangeLog:
2019-04-05 Pedro Franco de Carvalho <pedromfc@linux.ibm.com>
* linux-low.c (linux_get_auxv): Remove static. Return auxv entry
value in argument pointer, return 1 if the entry is found and 0
otherwise. Move comment.
(linux_get_hwcap, linux_get_hwcap2): Use modified linux_get_auxv.
* linux-low.h (linux_get_auxv): Declare.
* linux-ppc-low.c (is_elfv2_inferior): Use linux_get_auxv.

Move type stack handling to a new class
This introduces a new "type_stack" class, and moves all the parser
type stack handling to this class. Parsers that wish to use this
facility must now instantiate this class somehow. I chose this

Remove paren_depth global
This removes the "paren_depth" global. In most cases, it is made into
a static global in a given parser. I consider this a slight
improvement, because it makes it clear that the variable isn't used
for communication between different modules of gdb. The one exception
is the Rust parser, which already incorporates all local state into a
transient object; in this case the parser depth is now a member.

PowerPC bc extended branch mnemonics and "y" hints
This patch fixes a problem with disassembly of branch instructions
for processors complying with PowerPC ISA versions prior to version
2.0, ie. those that use "y" bit branch taken hints. Many of the
extended bcctr and bclr mnemonics that should have disassembled with a
"-" suffix, ie. not taken, did not display the "-" due to the ordering
in powerpc_opcodes. I believe it's been that way from the original
85dcf36d72b commit of ppc-opc.c.
I've also added a BH field (optional) to a few opcodes. This gives
better disassembly in raw mode, showing the branch taken hint in the
mnemonic as is done for bc. It would be reasonable to add a BH
field to all bcctr, bclr, and bctar extended mnemonics but that runs
into a small difficulty: Currently we print all or none of the
optional operands. That means for example that "bgectr cr2" would
display as "bgectr cr2,0" if a BH field is added to bgectr.
* ppc-opc.c (XLBH_MASK): Subtract off BH field from BB_MASK.
(powerpc_opcodes): Reorder bcctr and bclr extended mnemonics
to favour printing of "-" branch hint when using the "y" bit.
Allow BH field on bc{ctr,lr,tar}{,l}{-,+}.

local implementation in favor of 'target_waitstatus_to_string' (thanks!), but
introduced a small typing error:

gas: use literals/const16 for xtensa loop relaxation
Loop opcode relaxation that uses addi/addmi doesn't work well with other
relaxations that may cause code movement. Instead of encoding fixed loop
end offset in the relaxed sequence use l32r or a pair of const16 to load
loop end address. This way the address of the loop end gets a relocation
record and it gets updated appropriately.

RISC-V: Don't check ABI flags if no code section.
This fixes a glib build failure reported in PR 24389. Using ld -b binary
creates an object file with no elf header flags set which has the wrong ABI
info for riscv64-linux. But the file also has no code sections, so I added
code borrowed from the arm port that only checks the ELF header ABI flags if
there is a code section.

gdb/fortran: Handle internal function calls
If an convenience function is defined in python (or guile), then
currently this will not work in Fortran, instead the user is given
this message:
(gdb) set language fortran
(gdb) p $myfunc (3)
Cannot perform substring on this type
Compare this to C:
(gdb) set language c
(gdb) p $myfunc (3)
$1 = 1
After this patch we see the same behaviour in both C and Fortran.
I've extended the test to check that all languages can call the
convenience functions - only Fortran was broken.
When calling convenience functions in Fortran we don't need to perform
the same value preparation (passing by pointer) that we would for
calling a native function - passing the real value is fine.
gdb/ChangeLog:
* eval.c (evaluate_subexp_standard): Handle internal functions
during Fortran function call handling.
gdb/testsuite/ChangeLog:
* gdb.python/py-function.exp: Check calling helper function from
all languages.
* lib/gdb.exp (gdb_supported_languages): New proc.

gdb: Add $_cimag and $_creal internal functions
Add two new internal functions $_cimag and $_creal that extract the
imaginary and real parts of a complex value.
These internal functions can take a complex value of any type 'float
complex', 'double complex', or 'long double complex' and return a
suitable floating point value 'float', 'double', or 'long double'.
So we can now do this:
(gdb) p z1
$1 = 1.5 + 4.5 * I
(gdb) p $_cimag (z1)
$4 = 4.5
(gdb) p $_creal (z1)
$4 = 1.5
The components of a complex value are not strictly named types in
DWARF, as the complex type is itself the base type. However, once we
are able to extract the components it makes sense to be able to ask
what the type of these components is and get a sensible answer back,
rather than the error we would currently get. Currently GDB says:
(gdb) ptype z1
type = complex double
(gdb) p $_cimag (z1)
$4 = 4.5
(gdb) ptype $
type = <invalid type code 9>
With the changes in dwarf2read.c, GDB now says:
(gdb) ptype z1
type = complex double
(gdb) p $_cimag (z1)
$4 = 4.5
(gdb) ptype $
type = double
Which seems to make more sense.
gdb/ChangeLog:

* dwarf2read.c (dwarf2_init_complex_target_type): New function.

[GAS, Arm] CLI with architecture sensitive extensions
This patch adds a new framework to add architecture sensitive extensions, like
GCC does. This patch also implements all architecture extensions currently
available in GCC.
This framework works as follows. To enable architecture sensitive extensions
for a particular architecture, that architecture must contain an ARM_ARCH_OPT2
entry in the 'arm_archs' table. All fields here are the same as previous, with
the addition of a new extra field at the end to <name> it's extension table.
This <name>, corresponds to a <name>_ext_table of type 'struct arm_ext_table'.
This struct can be filled with three types of entries:
ARM_ADD (string <ext>, arm_feature_set <enable_bits>), which means +<ext> will
enable <enable_bits>
ARM_REMOVE (string <ext>, arm_feature_set <disable_bits>), which means
+no<ext> will disable <disable_bits>
ARM_EXT (string <ext>, arm_feature_set <enable_bits>, arm_feature_set
<disable_bits>), which means +<ext> will enable <enable_bits> and +no<ext>
will disable <disable_bits> (this is to be used instead of adding an
ARM_ADD and ARM_REMOVE for the same <ext>)
This patch does not disable the use of the old extensions, even if some of them
are duplicated in the new tables. This is a "in-between-step" as we may want to
deprecate the old table of extensions in later patches. For now, GAS will first
look for the +<ext> or +no<ext> in the new table and if no entry is found it
will continue searching in the old table, following old behaviour. If only an
ARM_ADD or an ARM_REMOVE is defined for <ext> and +no<ext> or +<ext> resp. is
used then it also continues to search the old table for it.
A couple of caveats:
- This patch does not enable the use of these architecture extensions with the
'.arch_extension' directive. This is future work that I will tend to later.
- This patch does not enable the use of these architecture extensions with the
-mcpu option. This is future work that I will tend to later.
- This patch does not change the current behaviour when combining an
architecture extension and using -mfpu on the command-line. The current
behaviour of GAS is to stage the union of feature bits enabled by both -march
and -mfpu. GCC behaves differently here, so this is something we may want to
revisit on a later date.

Add gdb.Value.format_string ()
The str () function, called on a gdb.Value instance, produces a string
representation similar to what can be achieved with the print command,
but it doesn't allow to specify additional formatting settings, for
instance disabling pretty printers.
This patch introduces a new format_string () method to gdb.Value which
allows specifying more formatting options, thus giving access to more
features provided by the internal C function common_val_print ().

Allow really large fortran array bounds: fortran type/value printers
This is the fortran part of the patch, including tests, which
are essentially unchanged from Siddhesh's original 2012 submission:
https://sourceware.org/ml/gdb-patches/2012-08/msg00562.html
There is, however, one large departure. In the above thread,
Jan pointed out problems with GCC debuginfo for -m32 builds
(filed usptream as gcc/54934). After investigating the issue,
I am dropping the hand-tweaked assembler source file to workaround
this case.
While I would normally do something to accommodate this, in
this case, given the ubiquity of 64-bit systems today (where
the tests pass) and the apparent lack of urgency on the compiler
side (by users), I don't think the additional complexity and
maintenance costs are worth it. It will be very routinely tested
on 64-bit systems. [For example, at Red Hat, we always
test -m64 and -m32 configurations for all GDB releases.]
gdb/ChangeLog:
From Siddhesh Poyarekar:
* f-lang.h (f77_get_upperbound): Return LONGEST.
(f77_get_lowerbound): Likewise.
* f-typeprint.c (f_type_print_varspec_suffix): Expand

Allow really large fortran array bounds: TYPE_LENGTH to ULONGEST
This series is revisit of Siddhesh Poyarekar's patch from back in
2012. The last status on the patch is in the following gdb-patches
thread:
https://sourceware.org/ml/gdb-patches/2012-08/msg00562.html
It appears that Tom approved the patch, but Jan had some issues
with a compiler error that made the test fail on -m32 test runs.
He wrote up a hand-tweaked .S file to deal with it. Siddesh said
he would update tests. Then nothing.
Siddesh and Jan have both moved on since.
The patch originally required a large precursor patch to work.
I have whittled this down to/rewritten the bare minimum, and this
first patch is the result, changing the type of TYPE_LENGTH
to ULONGEST from unsigned int.
The majority of the changes involve changing printf format
strings to use %s and pulongest instead of %d.
gdb/ChangeLog:
* ada-lang.c (ada_template_to_fixed_record_type_1): Use
%s/pulongest for TYPE_LENGTH instead of %d in format
strings.
* ada-typerint.c (ada_print_type): Likewise.
* amd64-windows-tdep.c (amd64_windows_store_arg_in_reg): Likewise.
* compile/compile-c-support.c (generate_register_struct): Likewise.
* gdbtypes.c (recursive_dump_type): Likewise.
* gdbtypes.h (struct type) <length>: Change type to ULONGEST.
* m2-typeprint.c (m2_array): Use %s/pulongest for TYPE_LENGTH
instead of %d in format strings.
* riscv-tdep.c (riscv_type_alignment): Cast second argument
to std::min to ULONGEST.
* symmisc.c (print_symbol): Use %s/pulongest for TYPE_LENGTH
instead of %d in format strings.
* tracepoint.c (info_scope_command): Likewise.
* typeprint.c (print_offset_data::update)
(print_offset_data::finish): Likewise.
* xtensa-tdep.c (xtensa_store_return_value)

Fix gdb.multi/multi-arch-exec.exp blocking under high load/slow gdb
When running multi-arch-exec.exp under valgrind, the test succeeds
when the machine is not loaded, but blocks when the machine is highly
loaded (e.g. when running the testsuite with valgrind with -j X
where X is one more than the nr of available cores).
The problem is that the hello program dies too early due to the alarm (30).
So, increase the alarm timer.
Note that this does not make the test take longer (it takes about
3.5 seconds on my system). As I understand, the alarm is just there
to avoid hello staying there forever in case of another problem.

Fix GDB being suspended SIGTTOU when running gdb.multi/multi-arch-exec.exp
When running under valgrind, multi-arch-exec.exp blocks forever.
Some (painful) investigation shows this is due to valgrind slowing
down GDB, and GDB has to output some messages at a different time,
when GDB does not have the terminal for output.
To reproduce the problem, you need to slow down GDB.
It can be reproduced by:
cd gdb/testsuite/outputs/gdb.multi/multi-arch-exec/
../../../../gdb -ex 'set debug lin-lwp 1' -ex 'break all_started' -ex 'run' ./2-multi-arch-exec
The above stops at a breakpoint. Do continue.
GDB is then suspended because of SIGTTOU.
The stacktrace that leads to the hanging GDB is:
(top-gdb) bt
at ../../binutils-gdb/gdb/exceptions.c:130
....
Alternatively, the same happens when doing
strace -o s.out ../../../../gdb -ex 'break all_started' -ex 'run' ./2-multi-arch-exec
And of course, valgrind is also sufficiently slowing down GDB to
reproduce this :).
Fix this by calling target_terminal::ours_for_output ();
at the beginning of follow_exec.
Note that all this terminal handling is not very clear to me:
* Some code takes the terminal, and then takes care to give it back to the inferior
if the terminal was belonging to the inferior.
(e.g. annotate_breakpoints_invalid).
* some code takes the terminal, but does not give it back
(e.g. update_inserted_breakpoint_locations).
* some code takes it, and unconditionally gives it back
(e.g. handle_jit_event)
* here and there, we also find
gdb::optional<target_terminal::scoped_restore_terminal_state> term_state;
before a (sometimes optional) call to ours_for_output.
And such calls to ours_for_output is sometimes protected by:
if (target_supports_terminal_ours ())
(e.g. exceptions.c: print_flush).
but most of the code calls it without checking if the target supports it.
* some code is outputting some errors, but only takes the terminal
after. E.g. infcmd.c: prepare_one_step

Fix stepping past unwritable kernel helper on nios2-linux-gnu.
This patch fixes a problem on nios2-linux-gnu with stepping past the
kernel helper __kuser_cmpxchg, which was exposed by the testcase
gdb.threads/watchpoint-fork.exp. The kernel maps this function into
user space on an unwritable page. In this testcase, the cmpxchg
helper is invoked indirectly from the setbuf call in the test program.
Since this target lacks hardware breakpoint/watchpoint support, GDB
tries to single-step through the program by setting software
breakpoints, and was just giving an error when it reached the function
on the unwritable page.
The solution here is to always step over the call instead of stepping
into it; cmpxchg is supposed to be an atomic operation so this
behavior seems reasonable. The hook in nios2_get_next_pc is somewhat
generic, but at present cmpxchg is the only helper provided by the
Linux kernel that is invoked by an ordinary function call. (Signal
return trampolines also go through the unwritable page but not by a
function call.)
Fixing this issue also revealed that the testcase needs a much larger
timeout factor when software single-stepping is used. That has also
been fixed in this patch.

Testsuite: set sysroot when using gdbserver
When testing using native-gdbserver and native-extended-gdbserver, the sysroot
is not set. This results in a warning from GDB and files are sent via the
remote protocol, which can be slow.
On Ubuntu 18.04 (unlike most distros) the debug versions of the standard
libraries are included by default in /usr/lib/debug/.
These file reads are causing a complete native-gdbserver run on the AArch64
buildbot slave to timeout after 2.5 hours. This is also causing the builds
to back up on the slave.
The solution is to ensure the sysroot is set to / for all local boards.
This drastically reduces the time of a test. For example, gdb.base/sigall.exp
drops from 23 seconds to 4 seconds.
A full native-gdbserver run on the AArch64 slave now takes 8 minutes.
gdb/testsuite/ChangeLog:
* boards/local-board.exp: set sysroot to /.

PR24390, Don't decode mtfsb field as a cr field
"mtfsb0 4*cr7+lt" doesn't make all that much sense, but unfortunately
glibc uses just that instead of "mtfsb0 28" to clear the fpscr xe bit.
So for backwards compatibility accept cr field expressions when
assembling mtfsb operands, but disassemble to a plain number.

Allocate minimal symbols with malloc
Before this commit, the array of 'struct minimal_symbol'
contained a last element that was a "null symbol". The comment in
minimal_symbol_reader::install was:
/* We also terminate the minimal symbol table with a "null symbol",
which is *not* included in the size of the table. This makes it
easier to find the end of the table when we are handed a pointer
to some symbol in the middle of it. Zero out the fields in the
"null symbol" allocated at the end of the array. Note that the
symbol count does *not* include this null symbol, which is why it
is indexed by mcount and not mcount-1. */
memset (&msymbols[mcount], 0, sizeof (struct minimal_symbol));
However, minimal_symbol_upper_bound was still based on the assumption
that the array of minsym is terminated by a minsym with a null symbol:
it is looping with:
for (i = 1; MSYMBOL_LINKAGE_NAME (msymbol + i) != NULL; i++)
Replace this NULL comparison by a logic that calculates how
many msymbol are following the msymbols from which we are starting from.
(Re-)tested on debian/amd64, natively and under valgrind.

Testsuite: Ensure interrupt-daemon-attach doesn't run forever
Looking at the AArch64 buildbot, I noticed about two dozen old instances of
interrupt-daemon-attach taking up a full 100% cpu each.
If the test fails then the test binary relies on an alarm to ensure it dies
after 60 seconds.
As per the Linux man page for alarm:
Alarms created by alarm() ... are not inherited by children created via fork.
Update the test to add an alarm in the child and also put a sleep in the
child loop so it does not constantly consume cpu.
Note I haven't managed to re-create why the test failed. This fix will just
stop it hanging and consuming cpu when it does.
gdb/testsuite/ChangeLog:
* gdb.base/interrupt-daemon-attach.c (main): Add alarm and sleep
in child.

gdb-gdb.py.in: Fix error when printing range type
I noticed that trying to print the contents of a struct main_type
would fail when the type was a TYPE_CODE_RANGE:
(gdb) p *type.main_type
$1 = Python Exception <class 'gdb.error'> There is no member named low_undefined.:
And indeed, Python is right, fields "low_undefined" has been removed
from struct range_bounds back in ... 2014! It was done when we introduced
dynamic bounds handling. This patch fixes gdb-gdb.py.in according to
the new structure.

(StructMainTypePrettyPrinter.bounds_img): Use new "bound_img"
method to compute the bounds of range types. Also print "[evaluated]"
if the bounds' values come from a dynamic evaluation.

gdb: Make python display_hint None handling defined behaviour
The documentation say that the display_hint method must return a
string to serve as a display hint, and then goes on to list some
acceptable strings.
However, if we don't supply the display_hint method then we get a
default display style behaviour and there's currently no way (in the
python api) to force this default behaviour.
The guile api allows #f to be used in order to force the default
display style behaviour, and this is documented.
Currently, using None in the python api also forces the default
display behaviour.
This commit extends the documentation to make returning None from the
display_hint method an official mechanism by which the user can get
the default display style.
I've extended one of the existing tests to cover this case.

* python.texi (Pretty Printing API): Document use of None for the
display_hint.
gdb/testsuite/ChangeLog:
* gdb.python/py-prettyprint.c (struct container) <is_map_p>: New

* gdb.python/py-prettyprint.exp: Add new tests.

gdb/testsuite: Make test names unique in gdb.python/py-prettyprint.exp
This makes the test names unique in gdb.python/py-prettyprint.exp, it
also switches to use gdb_breakpoint and gdb_continue_to_breakpoint
more so that we avoid test names with the source line number in - this
is bad if the test source ever changes as the test names will then
change.
One final change is to switch from using gdb_py_test_silent_cmd to use
gdb_test_no_output, the former should be used for running python
commands and can catch any thrown exception. However, in this case
the command being run is not a python command, its just a normal GDB
CLI command that produces no output, so lets use the appropriate
wrapper function.
gdb/testsuite/ChangeLog:
* gdb.python/py-prettyprint.exp: Use gdb_breakpoint and
gdb_continue_to_breakpoint more throughout this test.
(run_lang_tests) Supply unique test names, and use
gdb_test_no_output.

AArch64/Arm: Update testcases fixing endiannes and linux targets
This fixes the testcases that are failing due to my recent patch.
It turns out that the start address across baremetal and linux builds
isn't entirely predictable without a linker script. Since the address
themselves are not the important thing I am ignoring them now.
Secondly I was encoding data using .word using non 0 values, however
because .word is subjected to endiannes these non-zero values under
big-endian happen to fall into the encoding space of instructions which
changes the disassembly. Using 0 fixes this problem and the purpose of
the test still holds, though objdump will dump ... for data only sections,
which is ok as the data/insn mixed sections will test the patch.
The ARM Attributes sections is not important and is ignored.

Fix use-after-free in source_cache::get_source_lines
Commit ab42892fb7d2 ("Fix vertical scrolling of TUI source window")
introduced a use-after-free in source_cache::get_source_lines.
At the beginning of the method, we get the fullname of the symtab:
const char *fullname = symtab_to_fullname (s);
fullname points to the string owned by the symtab (s.fullname). When we
later do
scoped_fd desc = open_source_file (s);
s.fullname gets reallocated (even though the string contents may not
change). The fullname local variable now points to freed memory.
To avoid it, refresh the value of fullname after calling
open_source_file.
Here is the ASan report:

Arm: Fix Arm disassembler mapping symbol search.
Similar to the AArch64 patches the Arm disassembler has the same issues with
out of order sections but also a few short comings.
For one thing there are multiple code blocks to determine mapping symbols, and
they all work slightly different, and neither fully correct. The first thing
this patch does is centralise the mapping symbols search into one function
mapping_symbol_for_insn. This function is then updated to perform a search in
a similar way as AArch64.
Their used to be a value has_mapping_symbols which was used to determine the
default disassembly for objects that have no mapping symbols. The problem with
the approach was that it was determining this value in the same loop that needed
it, which is why this field could take on the states -1, 0, 1 where -1 means
"don't know". However this means that until you actually find a mapping symbol
or reach the end of the disassembly glob, you don't know if you did the right
action or not, and if you didn't you can't correct it anymore.
This is why the two jump-reloc-veneers-* testcases end up disassembling some
insn as data when they shouldn't.
Out of order here refers to an object file where sections are not listed in a
monotonic increasing VMA order.
The ELF ABI for Arm [1] specifies the following for mapping symbols:
1) A text section must always have a corresponding mapping symbol at it's
start.
2) Data sections do not require any mapping symbols.
3) The range of a mapping symbol extends from the address it starts on up to
the next mapping symbol (exclusive) or section end (inclusive).
However there is no defined order between a symbol and it's corresponding
mapping symbol in the symbol table. This means that while in general we look
up for a corresponding mapping symbol, we have to make at least one check of
the symbol below the address being disassembled.
When disassembling different PCs within the same section, the search for mapping
symbol can be cached somewhat. We know that the mapping symbol corresponding to
the current PC is either the previous one used, or one at the same address as
the current PC.
However this optimization and mapping symbol search must stop as soon as we
reach the end or start of the section. Furthermore if we're only disassembling
a part of a section, the search is a allowed to search further than the current
chunk, but is not allowed to search past it (The mapping symbol if there, must
be at the same address, so in practice we usually stop at PC+4).
lastly, since only data sections don't require a mapping symbol the default
mapping type should be DATA and not INSN as previously defined, however if the
binary has had all its symbols stripped than this isn't very useful. To fix
this we determine the default based on the section flags. This will allow the
disassembler to be more useful on stripped binaries. If there is no section
than we assume you to be disassembling INSN.

AArch64: Have -D override mapping symbol as documented.
The documentation for -D says that on Arm platforms -D should disassemble
data as instructions.
"If the target is an ARM architecture this switch also has the effect of
forcing the disassembler to decode pieces of data found in code sections
as if they were instructions. "
This makes it do as it says on the tincan so it's more consistent with
aarch32. The usecase here is for baremetal developers who have created
their instructions using .word directives instead if .insn.
Though for Linux users I do find this behavior somewhat non-optimal.
Perhaps there should be a new flag that just disassembles the values
following the actual mapping symbol?

AArch64: Fix AArch64 disassembler mapping symbol search
My previous patch for AArch64 was not enough to catch all the cases where
disassembling an out-of-order section could go wrong. It had missed the case
DATA sections could be incorrectly disassembled as TEXT.
Out of order here refers to an object file where sections are not listed in a
monotonic increasing VMA order.

AArch64: Fix disassembler bug with out-of-order sections
The AArch64 disassembler has an optimization that it uses to reduce the amount
it has to search for mapping symbols during disassembly. This optimization
assumes that sections are listed in the section header in monotonic increasing
VMAs. However this is not a requirement for the ELF specification.
Because of this when such "out of order" sections occur the disassembler would
pick the wrong mapping symbol to disassemble the section with.
This fixes it by explicitly passing along the stop offset for the current
disassembly glob and when this changes compared to the previous one we've seen
the optimization won't be performed. In effect this restarts the search from
a well defined starting point. Usually the symbol's address.
The existing stop_vma can't be used for this as it is allowed to be unset and
setting this unconditionally would change the semantics of this field.

Fix testsuite hangs when gdb_test_multiple body errors out
This commit fixes a regression in the testsuite itself, triggered by
errors being raised from within gdb_test_multiple, originally reported
by Pedro Franco de Carvalho's at
<https://sourceware.org/ml/gdb-patches/2019-03/msg00160.html>. Parts
of the commit message are based on his report.
This started happening due to a commit that was introduced recently,
and it can cause the testsuite to hang.
The commit that triggers this is:
fe1a5cad302b5535030cdf62895e79512713d738
[gdb/testsuite] Log wait status on process no longer exists error
That commit introduces a new "eof" block in gdb_test_multiple. That
is not incorrect itself, but dejagnu's remote_expect is picking that
block as the "default" action when an error is raised from within the
commands inside a call to gdb_test_multiple:
# remote_expect works basically the same as standard expect, but it
# also takes care of getting the file descriptor from the specified
# host and also calling the timeout/eof/default section if there is an
# error on the expect call.
#
proc remote_expect { board timeout args } {
I find that "feature" surprising, and I don't really know why it
exists, but this means that the eof section that remote_expect picks
as the error block can be executed even when there was no actual eof
and the GDB process is still running, so the wait introduced in the
commit that tries to get the exit status of GDB hangs forever, while
GDB itself waits for input.
This only happens when there are internal testsuite errors (not
testcase failures). This can be reproduced easily with a testcase
such as:
gdb_start
gdb_test_multiple "show version" "show version" {
-re ".*" {
error "forced error"
}
}
I think that working around this in GDB is useful so that the
testsuite doesn't hang in these cases.
Adding an empty "default" block at the end of the expect body in
gdb_test_multiple doesn't work, because dejagnu gives preference to
"eof" blocks:
if { $x eq "eof" } {
set save_next 1
} elseif { $x eq "default" || $x eq "timeout" } {
if { $error_sect eq "" } {
set save_next 1
}
}
And we do have "eof" blocks. So we need to make sure that the last
"eof" block is safe to use as the default error block. It's also
pedantically incorrect to print
"ERROR: Process no longer exists"
which is what we'd get if the last eof block we have was selected
(more below on this).
So this commit solves this by appending an "eof" with an empty
spawn_id list, so that it won't ever match.
Now, why is the first "eof" block selected today as the error block,
instead of the last one?
The reason is that remote_expect, while parsing the body to select the
default block to execute after an error, is affected by the comments
in the body (since they are also parsed).
If this comment in gdb_test_multiple
# patterns below apply to any spawn id specified.
is changed to
# The patterns below apply to any spawn id specified.
then the second eof block is selected and there is no hang.
Any comment at that same place with an even number of tokens also
works.
This is IMO a coincidence caused by how comments work in TCL.
Comments should only appear in places where a command can appear. And
here, remote_expect is parsing a list of options, not commands, so
it's not unreasonable to not parse comments, similarly to how this:
set a_list {
an_element
# another_element
}
results in a list with three elements, not one element.
The fact that comments with an even number of tokens work is just a
coincidence of how remote_expect's little state machine is
implemented.
I thought we could solve this by stripping out comment lines in
gdb_expect, but I didn't find an easy way to do that. Particularly, a
couple naive approaches I tried run into complications. For example,
we have gdb_test calls with regular expressions that include sequences
like "\r\n#", and by the time we get to gdb_expect, the \r\n have
already been expanded to a real newline, so just splitting the whole
body at newline boundaries, looking for lines that start with #
results in incorrectly stripping out half of the gdb_text regexp. I
think it's better (at least in this commit), to move the comments out
of the list, because it's much simpler and risk free.

(re-)fix the regcache leaks when detaching from an executable.
Commit 799efbe8e01ab8292c01f46ac59a6fb2349d4535 was supposed to fix

save the ptid before detach.
This commit (pushed as OBVIOUS, as the change was already reviewed/approved)
saves the ptid before the detach, as in the original reviewed patch

Have parser reset the innermost block tracker
I ran across a comment in symfile.c today:
/* Clear globals which might have pointed into a removed objfile.
FIXME: It's not clear which of these are supposed to persist
between expressions and which ought to be reset each time. */
It seems to me that this can be clarified: the parser entry points
ought to reset the innermost block tracker (and the expression context
block), and these should not be considered valid for code to use at
arbitrary times -- only immediately after an expression has been
parsed.
This patch implements this idea. This could be further improved by
removing the parser globals and changing the parser functions to
return this information, but I have not done this.
Tested by the buildbot.

In break-interp.exp, pie is explicitly set for some tests and assumed
to be disabled for the remainder.
Ensure pie is disabled for these tests when required.
In addition, add a pie option to gdb_compile to match the nopie option
and simplify use.

RISC-V: Fix linker crash in section symbol check.
sym is only set for local symbols. h is only set for global symbols. Gas
won't let me create a global section symbol, but bfd appears to have some
support for that, and I can't rule out that other assemblers might do this.
So we need to support both, and verify sym and h are non-NULL before using.

[BFD, AArch64, x86] Improve warning for --force-bti
The AArch64 linker option to turn on BTI (--force-bti) warns in case there are
input objects which have a missing GNU NOTE section for BTI. This patch is trying
to improve the warnings that come out.
In order to do so, I propose adding a new argument to elf_merge_gnu_properties
and the backend function merge_gnu_properties. This new argument makes sure
that we now pass both the objects along with the properties to which they
belong to. The x86 backend function has also been updated to match this
change.

Fix some dlx fails
Generic linker ELF targets using CREATE_OBJECT_SYMBOLS in their
scripts run into a problem. The file symbols are created by
_bfd_generic_link_output_symbols in each object file, in the section
corresponding to the CREATE_OBJECT_SYMBOLS section, typically .text.
If it so happens that the output .text section is stripped due to
being empty, then elf.c:assign_section_numbers won't assign an ELF
section number and swap_out_syms will report "unable to find
equivalent output section" for the object symbols. Fix this by
always keeping an output section with CREATE_OBJECT_SYMBOLS.
* ldlang.c (lang_size_sections_1): Set SEC_KEEP on
create_object_symbols_section.
* testsuite/ld-elf/pr22319.d: Don't xfail dlx.

Don't show "display"s twice in MI
If you run "gdb -i=mi2" and set a "display", then when "next"ing the
displays will be shown twice:
~"1: x = 23\n"
~"7\t printf(\"%d\\n\", x);\n"
~"1: x = 23\n"
*stopped,reason="end-stepping-range",frame={addr="0x0000000000400565",func="main",args=[],file="q.c",fullname="/tmp/q.c",line="7"},thread-id="1",stopped-threads="all",core="1"
The immediate cause of this is this code in mi_on_normal_stop_1:
print_stop_event (mi_uiout);
console_interp = interp_lookup (current_ui, INTERP_CONSOLE);
if (should_print_stop_to_console (console_interp, tp))
print_stop_event (mi->cli_uiout);
... which obviously prints the stop twice.
However, I think the first call to print_stop_event is intended just
to emit the MI *stopped notification, which explains why the source
line does not show up two times.
This patch fixes the bug by changing print_stop_event to only call
do_displays for non-MI-like ui-outs.

Add comments describing tui_ui_out and its fields, cleanup a bit
This commit add comments describing tui_ui_out and its fields, and
cleans up the code a little bit.
Also switch to using in-class initialization so that the initial
values can be seen alongside the comments.
I see no reason for initializing m_line as -1 instead of 0, since all
the checks in the .c file are of the form "> 0". AFAICS there's no
practical difference between -1 and 0. So it seems simpler to
initialize it as 0.
There's a bit of redundancy in tui_ui_out::do_field_string, which is
fixed by this commit.

Fix first time you type UP or DOWN in TUI's command window
The first time you type UP or DOWN arrow in the command window, GDB
should scroll the source window, but instead it displays the line
number and the file name in the command window(?).
What happens there is that the first time we call
tui_ui_out::do_field_int, it doesn't initialize m_line, because
m_start_of_line is -1, as set by the constructor; and then the
following call to tui_ui_out::do_field_string falls back to
cli_ui_out::do_field_string because m_line is zero.
The problem is caused by a typo in the C++ification of tui_ui_out,
commit 112e8700a6f, where m_line and m_start_of_line's initial values
were swapped from what they used to be:

Fix regression caused by minimal symbol changes
The earlier patch to change minimal symbol allocations to use xmalloc
erroneously left a call to obstack_blank in
minimal_symbol_reader::install. Because obstack_blank does not finish
the object allocation on an obstack, this in turn could cause invalid
memory reads in some situations.
This patch fixes the problem by removing the call. Tested on x86-64
Fedora 29; also verified with valgrind.

Improve/fix the TUI's current source line highlight
With styling enabled, I think the way we display the TUI's
highlighted/current line is very ugly and distracting. The problem in
my view is that we reverse foreground/background in colored text as
well, leading to rainbow of background colors.
This patch changes that to something that I find much more sensible --
only reverse the default foreground/background colors, leave styled
text colors alone. If the foreground color is not the default
(because the text was styled), leave the foreground color as is. If
e.g., the terminal is fg=BLACK, and bg=WHITE, and the style wants to
print text in RED, reverse the background color (print in BLACK), but
still print the text in RED.
Note: The new ui_file_style::set_fg method isn't called set_foreground
instead, because set_foreground is a macro in /usr/lib/term.h (ncurses).

Fix scrolling right in the TUI
This commit fixes two issues in scrolling right in the TUI:
#1 - Scrolling right with the arrow keys, the first keypress doesn't
do anything. The problem is that copy_source_line() checks if
(column < first_col), and because of the ++column directly before, it
basically starts with 1 instead of 0.
#2 - Scrolling right handles TABS and escaped characters as single
characters, which just looks weird. The problem is that there's a
spot that misses handling TABS.

Fix Ada "ptype" bug with array types
Using ptype on an array type in Ada can sometimes show an incorrect
high bound. This happens because ada_evaluate_subexp will create an
array with an incorrect upper bound in the EVAL_AVOID_SIDE_EFFECTS
case.
This patch fixes the problem by arranging to always create such an
array with valid bounds.

PR24355, segmentation fault in function called from ppc_finish_symbols
This one looks to be a bug going back to 2009, git commit e054468f6c
"STT_GNU_IFUNC support for PowerPC". That bug was carried over with
git commit 49c09209d0 "Rearrange PLT reloc output on powerpc".
If the refcount for an ifunc local sym plt entry was zero,
ppc_elf_size_dynamic_sections would correctly set plt.offset to -1 but
leave glink_offset uninitialized. That leads to occasional segfaults
(which can be made solid with MALLOC_PERTURB_=1 when using glibc).
So, guard the write_glink_stub call with plt.offset != -1. Also,
remove the totally ineffective attempt at writing multiple-use glink
stubs only once.

Because MSYMBOL_SET_LANGUAGE and MSYMBOL_SET_NAMES were only used from

Allocate minimal symbols with malloc
Currently, minimal symbols are allocated on the per-BFD obstack.
However, it is also possible for multiple symbol readers to create
minimal symbols for a given objfile. In this case, the minimal
symbols will be reallocated on the obstack, leading to some waste of
storage.
This is a memory leak, but I think it won't be caught by tools like
valgrind, because valgrind doesn't know about obstacks.
This patch fixes the problem by using malloc to allocate the storage
for minimal symbols.

Simplify per-BFD storage management
There's no reason that the objfile_per_bfd_storage must be allocated
via bfd_alloc. This patch changes objfile_per_bfd_storage to be
managed more simply, via ordinary new and delete; and moves some code
into its (new) destructor.
While doing this I also noticed an extra initialization of
language_of_main, and removed it.

Fix colors in TUI mode in MS-Windows build with ncurses
The MS-Windows port of ncurses fails to switch to a color pair if
one or both of the colors are the implicit default colors. This
change records the default colors when TUI is initialized, and
then specifies them explicitly when a color pair uses the default
colors. This allows color styling in TUI mode on MS-Windows.

Change pid_to_str to return std::string
Currently the target pid_to_str method returns a const char *, so many
implementations have a static buffer that they update. This patch
changes these methods to return a std::string instead. I think this
is cleaner and avoids possible gotchas when calling pid_to_str on
different ptids in a single statement. (Though no such calls exist
currently.)
This also updates various helper functions, and the gdbarch pid_to_str
methods.
I also made a best effort to fix all the callers, but I can't build
some of the *-nat.c files.
Tested by the buildbot.

Fix MI output for multi-location breakpoints
New in v2:
- Addressed comments about doc, updated the MI version table
- New doc for the Breakpoint information format
- New -fix-multi-location-breakpoint-output command, with associated
doc, test and NEWS updated accordingly
- Fixed the output, the locations list is now actually in the tuple
representing the breakpoint.
Various MI commands or events related to breakpoints output invalid MI
records when printing information about a multi-location breakpoint.
For example:
-break-insert allo
^done,bkpt={...,addr="<MULTIPLE>",...},{number="1.1",...},{number="1.2",...}
The problem is that according to the syntax [1], the top-level elements
are of type "result" and should be of the form "variable=value".
This patch changes the output to wrap the locations in a list:
^done,bkpt={...,addr="<MULTIPLE>",locations=[{number="1.1",...},{number="1.2",...}]}
The events =breakpoint-created, =breakpoint-modified, as well as the
-break-info command also suffer from this (and maybe others I didn't
find).
Since this is a breaking change for MI, we have to deal somehow with
backwards compatibility. The approach taken by this patch is to bump
the MI version, use the new syntax in MI3 while retaining the old syntax
in MI2. Frontends are expected to use a precise MI version (-i=mi2), so
if they do that they should be unaffected.
The patch also adds the command -fix-multi-location-breakpoint-output,
which front ends can use to enable this behavior with MI <= 2.

Factor out mi_ui_out instantiation logic
When re-reviewing this [1] I noticed that there were two spots encoding
the logic of instantiating an mi_ui_out object based on the interpreter
name ("mi", "mi1", "mi2" or "mi3"):
- mi_interp::init
- mi_load_progress
Both encode the logic to choose what the default version is when the
interpreter name is "mi". I had forgotten the one in mi_load_progress.
Therefore, I propose extracting that logic to a single function. I
started to add a new overload of mi_out_new, then realized the current
mi_out_new wasn't very useful, being just a thing wrapper around "new
mi_ui_out". So I ended up with just an mi_out_new function taking the
interp name as parameter.
I ran the gdb.mi tests, and verified manually the behavior (including
the load command).
[1] https://sourceware.org/ml/gdb-patches/2019-01/msg00427.html
gdb/ChangeLog:
* mi/mi-out.h (mi_out_new): Change parameter to const char *.
* mi/mi-out.c (mi_out_new): Change parameter to const char *,
instantiate mi_ui_out based on interpreter name.
* mi/mi-interp.c (mi_interp::init): Use the new mi_out_new.

[BFD, LD, AArch64, 3/3] Add --pac-plt to enable PLTs protected with PAC.
This is part of the patch series to add support for BTI and
PAC in AArch64 linker.
1) This patch adds new definitions of PAC enabled PLTs
and both BTI and PAC enabled PLTs.
2) It also defines the new dynamic tag DT_AARCH64_PAC_PLT
for the PAC enabled PLTs.
3) This patch adds a new ld command line option: --pac-plt.
In the presence of this option, the linker uses the PAC
enabled PLTs and marks with DT_AARCH64_PAC_PLT.
4) In case both BTI and PAC are enabled the linker should
pick PLTs enabled with both and also use dynamic tags for both.
All these are made according to the new AArch64 ELF ABI

[BFD, LD, AArch64, 2/3] Add --force-bti to enable BTI and to select BTI enabled PLTs
This is part of the patch series to add support for BTI and
PAC in AArch64 linker.
1) This patch adds a new ld command line option: --force-bti.
In the presence of this option, the linker enables BTI with the
GNU_PROPERTY_AARCH64_FEATURE_1_BTI feature. This gives out warning
in case of missing gnu notes for BTI in inputs.
2) It also defines a new set of BTI enabled PLTs. These are used either
when all the inputs are marked with GNU_PROPERTY_AARCH64_FEATURE_1_BTI
or when the new --force-bti option is used. This required adding new
fields in elf_aarch64_link_hash_table so that we could make the PLT
related information more generic.
3) It also defines a dynamic tag DT_AARCH64_BTI_PLT. The linker uses
this whenever it picks BTI enabled PLTs.
All these are made according to the new AArch64 ELF ABI

dwarf2: Align relocation within .debug_line section
All relocations specify a byte address. As dwarf debug information is
organized in octets, some relocations may not be aligned. While it
might be possible to define special relocations that operate at an
octet offset from their address, it's easier to ensure the relocations
are aligned by padding with "nop" statements.
In most dwarf sections this requirement is already fulfilled, only
relocations for symbol address within the .debug_line section can be
misaligned.

dwarf2: Pad size of .debug_line section.
As all dwarf debug information is organized in octets, the size of all
dwarf sections must be aligned to OCTETS_PER_BYTE. Most DWARF sections
meet this requirement, only the .debug_line section can reach an
arbitrary octet size.
In order to align the size to a multiple of OCTETS_PER_BYTE, the section
is padded with "nop" statements at the end.

Support TLS variables on FreeBSD/amd64.
Use the fs_base register to fetch the address of a thread's tcb and
calculate the address of the DTV array. This value is then passed to
fbsd_get_thread_local_address to compute the final variable address.
Note that fs_base is currently only available via the native target as
core dumps on FreeBSD do not store the value of fs_base.

Date: Tue Mar 12 13:39:02 2019 -0700
Add a helper function to resolve TLS variable addresses for FreeBSD.
The fbsd_get_thread_local_address function accepts the base address of
a thread's DTV array and the base address of an object file's link map
and uses this to compute a TLS variable's address. FreeBSD
architectures use an architecture-specific method to determine the
address of the DTV array pointer and call this helper function to
perform the rest of the address calculation.

Add a more general version of lookup_struct_elt_type.
lookup_struct_elt is a new function which returns a tuple of
information about a component of a structure or union. The returned
tuple contains a pointer to the struct field object for the component
as well as a bit offset of that field within the structure. If the
field names a field in an anonymous substructure, the offset is the
"global" offset relative to the original structure type. If noerr is
set, then the returned tuple will set the field pointer to NULL to
indicate a missing component rather than throwing an error.
lookup_struct_elt_type is now reimplemented in terms of this new
function. It simply returns the type of the returned field.
gdb/ChangeLog:
* gdbtypes.c (lookup_struct_elt): New function.
(lookup_struct_elt_type): Reimplement via lookup_struct_elt.
* gdbtypes.h (struct struct_elt): New type.

Handle an edge case for minisym TLS variable lookups.
If a TLS variable is provided by a minisym from a separate debug file,
the separate debug file is passed to
gdbarch_fetch_tls_load_module_address. However, the object files
stored in the shared object list are the original object files, not
the separate debug object files. In this case,
svr4_fetch_objfile_link_map was failing to find the link map entry
since the debug object file is not in its internal list, only the
original object file.
gdb/ChangeLog:
* solib-svr4.c (svr4_fetch_objfile_link_map): Look for
objfile->separate_debug_objfile_backlink if not NULL.

Support fs_base and gs_base on FreeBSD/i386.
The i386 BSD native target uses the same ptrace operations
(PT_[GS]ET[FG]SBASE) as the amd64 BSD native target to fetch and store
the registers.
The amd64 BSD native now uses 'tdep->fsbase_regnum' instead of
hardcoding AMD64_FSBASE_REGNUM and AMD64_GSBASE_REGNUM to support
32-bit targets. In addition, the store operations explicitly zero the
new register value before fetching it from the register cache to
ensure 32-bit values are zero-extended.

gdb/testsuite: Prepare for DejaGnu 1.6.2
Changes in DejaGnu 1.6.2 mean that our testsuite will no longer run.
This is because of some confusion over how the gdb.exp file is
handled.
The gdb.exp file is really the tool init file, which is loaded from
within the DejaGnu core, and it should not be loaded directly from any
other file in the testsuite.
DejaGnu tries to prevent the same library being loaded twice by
remembering the names of library files as they are loaded. Until
recently loading the tool init file in DejaGnu was very similar to
loading a library file, as a result, loading the gdb.exp tool init
file simply recorded 'gdb.exp' as having been loaded, future attempts
to load 'gdb.exp' as a library would then be ignored (as the file was
marked as already loaded).
DejaGnu has now changed so that it supports having both a tool init
file and a library with the same name, something that was not possible
before. What this means however is that when the core loads the
'gdb.exp' tool init file it no longer marks the library 'gdb.exp' as
having been loaded. When we then execute 'load_lib gdb.exp' we then
try to reload the 'gdb.exp' file.
Unfortunately our gdb.exp file can only be loaded once. It use of
'rename cd builtin_cd' means that a second attempt to load this file
will fail.
This was discussed on the DejaGnu list here:
http://lists.gnu.org/archive/html/dejagnu/2019-03/msg00000.html
and the suggested advice is that, unless we have some real requirement
to load the tool init file twice, we should remove calls to 'load_lib
gdb.exp' and rely on DejaGnu to load the file for us, which is what
this patch does.
I've tested with native X86-64/GNU Linux and see no regressions.

Don't use bfd_get_file_size in objdump
Compressed debug sections can have uncompressed sizes that exceed the
original file size, so we can't use bfd_get_file_size. objdump also
used bfd_get_file_size to limit reloc section size, but I believe the
underlying bug causing the PR22508 out of bounds buffer access was
that we had an integer overflow when calculating the reloc buffer
size. I've fixed that instead in most of the backends, som and
vms-alpha being the exceptions. SOM and vmd-alpha have rather more
serious bugs in their slurp_relocs routines that would need fixing
first if we want to fuss about making them safe against fuzzed object
files.
The patch also fixes a number of other potential overflows by using
the bfd_alloc2/malloc2/zalloc2 memory allocation functions.

Ensure 'help set/show print inferior-events' shows the example events.
Without this patch, the help stops after 'e.g.' :
(gdb) apropos \(inferior\|thread\) event
set print inferior-events -- Set printing of inferior events (e.g.
set print thread-events -- Set printing of thread events (such as thread start and exit)
show print inferior-events -- Show printing of inferior events (e.g.
show print thread-events -- Show printing of thread events (such as thread start and exit)
Using the same notation as for the thread evenets (i.e. 'such as') gives:
(gdb) apropos \(inferior\|thread\) event
set print inferior-events -- Set printing of inferior events (such as inferior start and exit)
set print thread-events -- Set printing of thread events (such as thread start and exit)
show print inferior-events -- Show printing of inferior events (such as inferior start and exit)
show print thread-events -- Show printing of thread events (such as thread start and exit)

PR24311, FAIL: S-records with constructors
Not padding string merge section output to its alignment can cause
failures of the S-record tests when input string merge sections are
padded, since the ELF linker output for the single string section
would shrink compared to the SREC linker output. That might result in
following sections having different addresses.
On the other hand, padding string merge section output when input
string merge sections are *not* padded can also cause failures, in
this case due to the ELF linker output for the string section being
larger (due to padding) than the SREC linker output.
It would be better to write a more robust test, but it is also nice
to leave input unchanged when no string merges occur.

* merge.c (merge_strings): Return secinfo. Don't pad section
to alignment here.
(_bfd_merge_sections): Pad section to alignment here, if input
sections contributing to merged output all pad to alignment.

Fix normal_stop latent bug
TARGET_WAITKIND_NO_RESUMED doesn't have an associated event thread, so
we shouldn't be referring to inferior_thread() assuming it points to
one.
This was caught on the multi-target branch, where we always switch to
no-thread-selected whenever we start handling an event, exactly to
catch places that incorrectly use "inferior_ptid/inferior_thread()"
without switching to the right event thread / target.
Here, on the branch, we assert in inferior_thread() because
TARGET_WAITKIND_NO_RESUMED doesn't have an associated event thread, so
inferior_ptid is still null_ptid.

Remove last cleanups from stabsread.c
This removes the last cleanups from stabsread.c. Similar code in
dwarf2read.c was C++-ified, but considering that stabs are deprecated,
it seemed simpler to just change these allocations to use an obstack
and leave the data structures in place.
This patch renames field_info to stabs_field_info -- adding a
constructor here provoked a bug due to the resulting ODR violation.

gdb/fortran: Handle older TYPE*SIZE typenames
This patch adds support for the older TYPE*SIZE typenames that are
still around in older code.
For implementation this currently reuses the kind mechanism, as under
gFortran the kind number is equivalent to the size, however, this is
not necessarily true for all compilers. If the rules for other
compilers are better understood then this code might need to be
improved slightly to allow for a distinction between size and kind,
however, adding this extra complexity now seems pointless.

gdb/fortran: Use TYPE_CODE_CHAR for character types
Switch to using TYPE_CODE_CHAR for character types. This appears to
have little impact on the test results as gFortran uses the
DW_TAG_string_type to represent all character variables (as far as I
can see). The only place this has an impact is when the user casts a
variable to a character type, in which case GDB does now use the CHAR
type, and prints the variable as both a value and a character, for
example, before:
(gdb) p ((character) 97)
$1 = 97
and after:
(gdb) p ((character) 97)
$1 = 97 'a'

gdb/fortran: Add Fortran 'kind' intrinsic and keyword
The 'kind' keyword has two uses in Fortran, it is the name of a
builtin intrinsic function, and it is also a keyword used to create a
type of a specific kind.
This commit adds support for using kind as an intrinsic function, and
also adds some initial support for using kind to create types of a
specific kind.
This commit only allows the creation of the type 'character(kind=1)',
however, it will be easy enough to extend this in future to support
more type kinds.
The kind of any expression can be queried using the kind intrinsic
function. At the moment the kind returned corresponds to the size of
the type, this matches how gfortran handles kinds. However, the
correspondence between kind and type size depends on the compiler
and/or the specific target, so this might not be correct for
everyone. If we want to support different compilers/targets in future
the code to compute the kind from a type will need to be updated.

Testsuite: Ensure changing directory does not break the log file
get_compiler_info switches to a new log file before checking the compiler
to ensure the checks are not logged. Afterwards it restores back to using
the original log file. However, the logfile uses a relative path name -
if the current test has changed the current directory then all further
output for the test will be lost. This can confuse the code that collates
the main gdb.log file at the end of a FORCE_PARALLEL run.
fullpath-expand.exp calls gdb_compile after changing the current directory.
The "Ensure stack protection is off for GCC" patch added a call to
get_compiler_info from inside of gdb_compile, causing log file collection
to break for FORCE_PARALLEL runs.
The ideal solution would be to ensure the log file is always created using
an absolute path name. However, this is set at multiple points in
Makefile.in and in some instances just relies on dejagnu common code to set
the log file directory to "."
The simpler and safer solution is to override the builtin cd function. The
new function checks the current log file and if the path is relative, then
it resets the logging using an absolute path. Finally it calls the builtin
cd. This ensures get_compiler_info (and any other code) can correctly
backup and restore the current log file.
gdb/testsuite/ChangeLog:
* lib/gdb.exp (builtin_cd): rename of cd.
(cd): Override builtin.

Fortran function calls with arguments
Prior to this patch, calling functions on the inferior with arguments and
then using these arguments within a function resulted in an invalid
memory access. This is because Fortran arguments are typically passed as
pointers to values.
It is possible to call Fortran functions, but memory must be allocated in
the inferior, so a pointer can be passed to the function, and the
language must be set to C to enable C-style casting. This is cumbersome
and not a pleasant debug experience.
This patch implements the GNU Fortran argument passing conventions with
caveats. Firstly, it does not handle the VALUE attribute as there is
insufficient DWARF information to determine when this is the case.
Secondly, functions with optional parameters can only be called with all
parameters present. Both these cases are marked as KFAILS in the test.
Since the GNU Fortran argument passing convention has been implemented,
there is no guarantee that this patch will work correctly, in all cases,
with other compilers.
Despite these limitations, this patch improves the ease with which
functions can be called in many cases, without taking away the existing
approach of calling with the language set to C.

Change the_dummy_target to be a global
While debugging gdb, I printed the target stack and got:
(top-gdb) p g_target_stack
$10 = {
m_top = thread_stratum,
m_stack = {0x142b0b0, 0x13da600 <exec_ops>, 0x1c70690, 0x13d63b0 <ravenscar_ops>, 0x0, 0x0, 0x0}
}
(This is clearly from before the change to make ravenscar
multi-target-capable.)
Here, 0x142b0b0 is the singleton dummy target. It seems to me that
since this is always a singleton, it would be a bit nicer if it were a
global, so that it would be noted in the above.
This patch implements this idea, and now I get:
(top-gdb) p g_target_stack
$2 = {
m_top = dummy_stratum,
m_stack = {0x1f1b040 <the_dummy_target>, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0}
}

to me.

Small fix to gdb.Value constructor doc
The synopsis of the two-parameters form of the gdb.Value constructor is
currently shown as
Value.__init__ (val, [, type ])
in the documentation.
First, there is an extra comma, which I think we can remove in any
case.
Then, since the type parameter is not optional, I would not put in
between square brackets. Those usually indicate that something is
optional.
With this patch, it appears as:
Value.__init__ (val, type)

Remove excess calls to gdb_flush
A customer noticed some mildly odd MI output, where CLI output was
split into multiple MI strings at unusual boundaries, like this:
~"$1 = (b => true"
~", p => 0x407260"
This is technically correct according to the MI spec, but still
unusual, in that there's no particular reason for the string to be
split where it is.
I tracked this down to a call to gdb_flush in generic_val_print.
Then, I went through all calls to gdb_flush and removed the ones I
thought were superfluous. In particular:
* Any call in the value-printing code;
* Likewise the type-printing code (just a single call); and
* Any call that immediately followed a printf that obviously
ended with a newline, my belief being that gdb's standard output
streams are line buffered (by inheriting the behavior from stdio)
Regression tested on x86-64 Fedora 29.
I didn't add a new test case. I tend to think we don't necessarily
want to specify this behavior in the tests. Let me know what you
think of this.

Use '$enable_unittest' instead of '$development' on gdbserver/configure.srv (for 'aarch64*-*-linux*' case)
On commit 8ecfd7bd4acd69213c06fac6de9af38299123547 ("Add parameter to
allow enabling/disabling selftests via configure") it seems that I
forgot to use the proper '$enable_unittest' variable when checking to
see whether to add selftest-related objects to 'srv_regobj'. This
causes a build failure on Aarch64 when 'development=false' (which is
the case for the 8.3 branch) and 'enable_unittest=true'.
This patch fixes the problem by using '$enable_unittest' instead of
'$development' when performing the check. As a reminder, it's
important to notice that '$enable_unittest's default value (i.e., when
the option '--enable-unit-tests' is not passed to configure) is the
same as '$development', so this patch doesn't affect the current
build.
I'd like to install this patch both on master and on the 8.3 branch.
OK?

gdbserver short-circuit-argument-list failures
This patch fixes test case failures observed when running
short-circuit-argument-list.exp with gdb server boards. Thanks to Sergio
Durigan Junior for pointing this out.
Assertions failed with the native{,-extended}-gdbserver boards as the
standard output from the test program appears in a different location
than observed on non-gdbserver boards. This standard output was used to
determine whether a function, which had been logically short-circuited,
was called or not. Since the location of the standard out cannot be
relied upon to verify this, a new mechanism was needed.
The test program now records function calls in variables named the same
as the function with a "_called" suffix. These variables can then be
queried from the test case to verify the occurrence of a call.
A method to reset the call counts has been included in the test case, so
that any future assertions added to this test can ensure a fresh set of
initial values before proceeding. Not resetting values between groups of
assertions creates a dependency between them, which increases the
likelihood that a single failure causes subsequent assertions to fail.
Regression tested on x86_64, aarch64 and ppc64le.
Regression tested with Ada on x86_64.
Regression tested with the native{,-extended}-gdbserver boards on x86_64.

Binutils: Always skip only 1 byte for CIE version 1's return address register.
According to the specification for the CIE entries, when the CIE version is 1 then
the return address register field is always 1 byte. Readelf does this correctly in
read_cie in dwarf.c but ld does this incorrectly and always tries to read a
skip_leb128. If the value here has the top bit set then ld will incorrectly read
at least another byte, causing either an assert failure or an incorrect address to
be used in eh_frame.
I'm not sure how to generate a generic test for this as I'd need to write assembly,
and it's a bit hard to trigger. Essentially the relocated value needs to start with
something that & 0x70 != 0x10 while trying to write a personality.

Testsuite: Catch gdbserver socket listen errors
When launching gdbserver, the testsuite checks for binding failure but
does not check for failure to listen to socket error (which can happen
due to another gdbserver binding to the socket at the same time).
When this error occurs, the test will ignore the error and connect GDB
to the failed port. This may succeed and GDB will now be connected to
the gdbserver from another test. This eventually causes both tests to
fail.
When running the tests suite with native-gdbserver across many cores,
this issue may happen once or twice, each causing random failures for
two .exp testscripts.
Example gdb.log output for the failure:
The testsuite sucessfully notices a failure to connect to port 2348.
It launches again with port 2349, which also fails. The testsuite
ignores this error and uses gdb to connect to the port - which succeeds.

Fix regcache leak, and avoid possible regcache access after detach.
Valgrind reports leaks like the below in various tests,
e.g. gdb.threads/attach-slow-waitpid.exp, gdb.ada/task_switch_in_core.exp, ...
Fix the leak by clearing the regcache when detaching from an inferior.
Note that these leaks are 'created' when GDB exits,
when the regcache::current_regcache is destroyed : the elements
of the forward_list are pointers, and the 'pointed to' memory is not
deleted by the forward_list destructor.
Nevertheless, fixing this leak is good as it makes a bunch of
tests 'leak clean'.
Also, it seems strange to keep a register cache for a process from
which GDB detached : it is not clear if this cache is still valid
after detach. And effectively, when clearing only the regcache,
(and not the frame cache), then the frame cache was still 'pointing'
at this regcache and was used when switching to the child process
in the test gdb.threads/watchpoint-fork.exp, which seems strange.
So, we solve the leak and avoid possible accesses to the regcache
and frame cache of the detached inferior, by clearing both the
regcache and the frame cache.
Tested on debian/amd64, natively, under Valgrind,
and with make check RUNTESTFLAGS="--target_board=native-gdbserver".

Make 'show width/height' display "unlimited" when capped for readline
When we cap the height/width sizes before passing to readline, tweak
the corresponding command variable to show "unlimited":
(gdb) set height 0x8000
(gdb) show height
Number of lines gdb thinks are in a page is unlimited.
Instead of the current output:

Prevent overflow in rl_set_screen_size
GDB calls rl_set_screen_size in readline with the current screen size,
measured in rows and columns. To represent "infinite" sizes, GDB
passes in INT_MAX; however, since rl_set_screen_size internally
multiplies the number of rows and columns, this causes a signed
integer overflow. To prevent this we can instead pass in the
approximate square root of INT_MAX (which is still reasonably large),
so that even when the number of rows and columns is "infinite" we
don't overflow.

Use Python 2.[67] / 3.X / PEP 3118 buffer protocol
This patch removes the non-IS_PY3K code in infpy_write_memory()
and infpy_search_memory(). In both cases, the remaining code
from these ifdefs is related to use of the PEP 3118 buffer protocol.
(Deleted code is either due to simplification or related to use of the
old buffer protocol.) PEP 3118 is sometimes referred to as the "new"
buffer protocol, though it's not that new anymore.
The link below describes new features in Python 2.6. In particular,
it says that the buffer protocol described by PEP 3118 is in Python
2.6. It also says (at the top of the page) that Python 2.6 was
released on Oct 1, 2008.
https://docs.python.org/3/whatsnew/2.6.html#pep-3118-revised-buffer-protocol
The last security release for the Python 2.6 series was 2.6.9. It was
released on Oct 29, 2013. According to this document...
https://www.python.org/download/releases/2.6.9/
...support for the 2.6 series has ended:
With the 2.6.9 release, and five years after its first release,
the Python 2.6 series is now officially retired. All official
maintenance for Python 2.6, including security patches, has ended.
For ongoing maintenance releases, please see the Python 2.7
series.
As noted earlier, Python 2.6, Python 2.7, and Python 3.X all have
support for the PEP 3118 buffer protocol. Python releases prior
to 2.6 use an older buffer protocol. Since Python 2.6 has been
retired for a good while now, it seems reasonable to me to remove
code using the older buffer protocol from GDB.
I have also simplified some of the code via use of the Py_buffer
unique_ptr specialization which I introduced in the two argument
gdb.Value constructor patch series. Therefore, there is a dependency
on patch #1 from that series.
I have tested against both Python 2.7.15 and 3.7.2. I see no
regressions among the non-racy tests. I've also verified that
PyBuffer_Release is being called when the affected functions exit
while running the tests in gdb.python/py-inferior.exp by hand. I've
also tried running valgrind on GDB while running this test, but I'm
puzzled by the results that I'm seeing - I'm seeing no additional
leaks when I comment out the Py_buffer_up lines that I introduced.
That said, I'm not seeing any leaks that obviously originate from
either infpy_write_memory() or infpy_search_memory().
gdb/ChangeLog:
* python/py-inferior.c (infpy_write_memory): Remove non-IS_PY3K
code from these functions. Remove corresponding ifdefs. Use
Py_buffer_up instead of explicit calls to PyBuffer_Release.
Remove gotos and target of gotos.
(infpy_search_memory): Likewise.

Testsuite: Allow multiple lines of "as" in testsuite.
Committed on behalf of Matthew Malcomson.
This allows checking the command line parsing more easily than before by
allowing many command line invokations from the same .d file.
Each line is used as a set of flags, and the tests are ran against the output
of the assembler with each set.
Each line of assembler is treated as another set of tests (as if the test file
were copied to another with a different #as: line).
This patch includes some example uses where multiple testcases can be merged
into one file using this new functionality.

gdb: Handle alignment for C++ structures with static members
In 'type_align' when computing the alignment of a structure we should
not consider the alignment of static structure members, these are
usually stored outside of the structure and therefore don't have any
impact on the structures alignment requirements.
I've extended the existing alignment calculating test to compile in
both C and C++ now so that we can create structures with static
members.

* gdbtypes.c (type_align): Don't consider static members when

type_align function was structured so that for "basic" types (int,
float, etc) the gdbarch_type_align hook was called, which for
"compound" types (arrays, structs, etc) the common type_align code has
a fixed method for how to extract a "basic" type and would then call
itself on that "basic" type.
The problem is that if an architecture wants to modify the alignment
rules for a "compound" type then this is not currently possible.
In the revised structure, all types pass through the
gdbarch_type_align method. If this method returns 0 then this
indicates that the architecture has no special rules for this type,
and GDB should apply the default rules for alignment. However, the
architecture is free to provide an alignment for any type, both
"basic" and "compound".
After this commit the default alignment rules now all live in the
type_align function, the default_type_align only ever returns 0,
meaning apply the default rules.
I've updated the 3 targets (arc, i386, and nios2) that already
override the gdbarch_type_align method to fit the new scheme.
Tested on X86-64/GNU Linux with no regressions.
gdb/ChangeLog:
* arc-tdep.c (arc_type_align): Provide alignment for basic types,
return 0 for other types.
* arch-utils.c (default_type_align): Always return 0.
* gdbarch.h: Regenerate.
* gdbarch.sh (type_align): Extend comment.
* gdbtypes.c (type_align): Add additional comments, always call
gdbarch_type_align before applying the default rules.
* i386-tdep.c (i386_type_align): Return 0 as the default rule,
generic code will then apply a suitable default.
* nios2-tdep.c (nios2_type_align): Provide alignment for basic
types, return 0 for other types.

gdb/riscv: Use legacy register numbers in default target description
When the target description support was added to RISC-V, the register
numbers assigned to the fflags, frm, and fcsr control registers in the
default target descriptions didn't match the register numbers used by
GDB before the target description support was added.
What this means is that if a tools exists in the wild that is using
hard-coded register number, setup to match GDB's old numbering, then
this will have been broken (for fflags, frm, and fcsr) by the move to
target descriptions. QEMU is such a tool.
There are a couple of solutions that could be used to work around this
issue:
- The user can create their own xml description file with the
register numbers setup to match their old tool, then load this by
telling GDB 'set tdesc filename FILENAME'.
- Update their old tool to use the newer default numbering scheme, or
better yet add proper target description support to their tool.
- We could have RISC-V GDB change to maintain the old defaults.
This patch changes GDB back to using the old numbering scheme.
This change is only visible to remote targets that don't supply their
own xml description file and instead rely on GDB's default numbering.
Note that even though 32bit-cpu.xml and 64bit-cpu.xml have changed,
the corresponding .c file has not, this is because the numbering added
to the registers in the xml files is number 0, this doesn't result in
any new C code being generated .
gdb/ChangeLog:
* features/riscv/32bit-cpu.xml: Add register numbers.
* features/riscv/32bit-fpu.c: Regenerate.
* features/riscv/32bit-fpu.xml: Add register numbers.
* features/riscv/64bit-cpu.xml: Add register numbers.
* features/riscv/64bit-fpu.c: Regenerate.
* features/riscv/64bit-fpu.xml: Add register numbers.

Define gdb.Value(bufobj, type) constructor
Provided a buffer BUFOBJ and a type TYPE, construct a gdb.Value object
with type TYPE, where the value's contents are taken from BUFOBJ.
E.g...
(gdb) python import struct
(gdb) python unsigned_int_type=gdb.lookup_type('unsigned int')
(gdb) python b=struct.pack('=I',0xdeadbeef)
(gdb) python v=gdb.Value(b, unsigned_int_type) ; print("%#x" % v)
0xdeadbeef
This two argument form of the gdb.Value constructor may also be used
to obtain gdb values from selected portions of buffers read with
Inferior.read_memory(). The test case (which is in a separate patch)
demonstrates this use case.

Fix crash when loading dwp files
When loading dwp files, we create an array of ELF sections indexed by the ELF
section index in the dwp file. The size of this array is calculated by
section_count, as returned by bfd_count_sections, plus 1 (to account for the
null section at index 0). However, when loading the bfd file, strtab/symtab
sections are not added to the list, nor do they increment section_count, so
section_count is actually smaller than the number of ELF sections.
This happens to work when using GNU dwp, which lays out .debug section first,
with sections like .shstrtab coming at the end. Other tools, like llvm-dwp, put
.strtab first, and gdb crashes when loading those dwp files.
For instance, with the current state of gdb, loading a file like this:
$ readelf -SW <file.dwp>
[ 0] <empty>
[ 1] .debug_foo PROGBITS ...
[ 2] .strtab STRTAB ...
... results in section_count = 2 (.debug is the only thing placed into
bfd->sections, so section_count + 1 == 2), and sectp->this_idx = 1 when mapping
over .debug_foo in dwarf2_locate_common_dwp_sections, which passes the
assertion that 1 < 2.
However, using a dwp file produced by llvm-dwp:
$ readelf -SW <file.dwp>
[ 0] <empty>
[ 1] .strtab STRTAB ...
[ 2] .debug_foo PROGBITS ...
... results in section_count = 2 (.debug is the only thing placed into
bfd->sections, so section_count + 1 == 2), and sectp->this_idx = 2 when mapping
over .debug_foo in dwarf2_locate_common_dwp_sections, which fails the assertion
that 2 < 2.
The assertion hit is:
gdb/dwarf2read.c:13009: internal-error: void dwarf2_locate_common_dwp_sections(bfd*, asection*, void*): Assertion `elf_section_nr < dwp_file->num_sections' failed.
This patch changes the calculation of section_count to use elf_numsections,
which should return the actual number of ELF sections.

Back when I proposed the '--readnever' feature, I somehow forgot or

using '--readnever'.
We've been carrying this patch on Fedora GDB for quite some time, and
as expected the corefiles generated by gcore on Fedora don't have

generate corefiles using '--readnever'.

Look for build-id-based separate debug files under the sysroot
When looking for a separate debug file that matches a given build-id,
GDB only looks in the host's debug dir (typically /usr/lib/debug). This
patch makes it look in the sysroot as well. This is to match the
behavior of GDB when using debuglink-based separate debug files,
introduced in :
402d2bfec42 ("Look for separate debug files in debug directories under a sysroot.")
In the following example, my sysroot is "/tmp/sysroot" and I am trying
to load symbols for
/tmp/sysroot/usr/lib/arm-linux-gnueabihf/gconv/EBCDIC-AT-DE.so. This is
the current behavior:

In the original code, there is a suspicious "abfd.release ()" in
build_id_to_debug_bfd, that I don't understand. If a file with the
right name exists but its build-id note doesn't match, we release (leak)
our reference, meaning the file will stay open? I removed it in the new
code, so that the reference is dropped if we end up not using that file.
I tested briefly by corrupting a separate debug file to trigger this
code, nothing exploded.

Fix symtab/23853: symlinked default symtab

in default symtabs that are symlinks. For example:
(gdb) list
11 GNU General Public License for more details.

14 along with this program. If not, see <http://www.gnu.org/licenses/>. */

24 {
25 return foo ();
26 }
(gdb) b 19
No line 19 in the current file.
Make breakpoint pending on future shared library load? (y or [n])
The problem here is that when create_sals_line_offset sets the default
symtab, it immediately calls symtab_to_fullname, passing that fullname
to collect_symtabs_from_filename to find all matching symtabs. This
fails because we end up looking for a symtab with the name of the
actual file on disk (which is different in this case because of the
symlink) instead of the one stored in the debug info.
Since we already have the lookup name of the default symtab, use it
instead of the fullname. [This fullname thing was originally added
in 2007 in a series dealing with *displaying* absolute file names.
Clearly, this instance has nothing to do with the display of file names.]

Disable styling when running in batch mode
The GCC Guality testsuite within GCC compiles C/C++ files in GCC at
various optimization levels then debugs them in GDB, checking that
program values can be read. This is done within the dejagnu framework.
The new style options in GDB have broken many of the tests due to the
testsuite being unable to process the new control characters. The fix
in Guality is to either to improve the string matching or to disable
styling on the cli or init file (after checking gdb is recent enough
to support styling).
This fix will also need making an any other testsuites in the wild
that use GDB.
An alternative would be to automatically disable styling when using GDB
in batch mode. The reasoning here is that batch mode is only used when
automating GDB and any output will be processed later either with text
processing tools or viewed in text editors, many of these will not
correctly handle the control characters by default. This ensures GDB
continues to work as expected. Anyone who explicitly wants styling in
batch mode can enable it either in the init file or adding to the batch
file - but that would not be the standard use case.
Patch simply disables style after reading the batch command flag, before
reading in the init file or batch file.

* main.c (captured_main_1): Disable styling in batch mode.

PowerPC __tls_get_addr arg parsing
The syntax we ended up with for -m32 -fPIC calls to __tls_get_addr is
rather weird.
bl __tls_get_addr+0x8000(gd0@tlsgd)@plt
This came about by accident, probably due to requiring the arg reloc
before the call reloc.
Of course the @plt really belongs with __tls_get_addr since it affects
the call rather than the call arg, and it isn't a great deal of
trouble to ensure the relocs are emitted in the correct order. This
patch supports a newer syntax, like so:
bl __tls_get_addr+0x8000@plt(gd0@tlsgd)

Fix error message and use-after-free on errors in nested sourced files
Errors that happen in nested sourced files (when a sourced file sources
another file) lead to a wrong error message, or use-after-free.
For example, if I put this in "a.gdb":
command_that_doesnt_exist
and this in "b.gdb":
source a.gdb
and try to "source b.gdb" in GDB, the result may look like this:
(gdb) source b.gdb
b.gdb:1: Error in sourced command file:
_that_doesnt_exist:1: Error in sourced command file:
Undefined command: "command_that_doesnt_exist". Try "help".
Notice the wrong file name where "a.gdb" should be. The exact result
may differ, depending on the feelings of the memory allocator.
What happens is:
- The "source a.gdb" command is saved by command_line_append_input_line
in command_line_input's static buffer.
- Since we are sourcing a file, the script_from_file function stores the
script name (a.gdb) in the source_file_name global. However, it doesn't
do a copy, it just saves a pointer to command_line_input's static buffer.
- The "command_that_doesnt_exist" command is saved by
command_line_append_input_line in command_line_input's static buffer.
Depending on what xrealloc does, source_file_name may now point to
freed memory, or at the minimum the data it was pointing to was
overwritten.
- When the error is handled in script_from_file, we dererence
source_file_name to print the name of the file in which the error
occured.
To fix it, I made source_file_name an std::string, so that keeps a copy of
the file name instead of pointing to a buffer with a too small
lifetime.
With this patch, the expected filename is printed, and no use-after-free
occurs:
(gdb) source b.gdb
b.gdb:1: Error in sourced command file:
a.gdb:1: Error in sourced command file:
Undefined command: "command_that_doesnt_exist". Try "help".
I passed explicit template parameters to make_scoped_restore
(<std::string, const std::string &>), so that the second parameter is
passed by reference and avoid a copy.
It was not as obvious as I first thought to change gdb.base/source.exp
to test this, because source commands inside sourced files are
interpreted relative to GDB's current working directory, not the
directory of the currently sourced file. As a workaround, I moved the
snippet that tests errors after the snippet that adds the source
directory to the search path. This way, the "source source-error-1.gdb"
line in source-error.exp manages to find the file.
For reference, here is what ASAN reports when use-after-free occurs:
(gdb) source b.gdb

Minor Ada task cleanups
While working on the Ada task code, I noticed a few things that could
be cleaned up:
* task_list_valid_p was not set in all cases in ada_build_task_list.
This causes many needless re-fetches of the task list.
* task_list_valid_p can be bool, and various functions can also return
bool.
* Nothing checks the return value of read_known_tasks, so it can be
changed to return void.
* The call to ada_build_task_list in
ravenscar_thread_target::update_thread_list is redundant, because
this is the first thing done by iterate_over_live_ada_tasks.
Tested using the internal AdaCore test suite against a ravenscar
target.

gdb: Allow gdbarch to override alignment for method and member pointers
The code in type_align (gdbtypes.c) currently hard-codes the rules for
aligning method and member pointers. It would seem better to forward
these types through the gdbarch hook, so that an architecture could
override the alignment of these types if needed.
Only 3 architectures currently override the gdbarch alignment hook,
these are arc, i386, and nio2.
For arc and nios the alignment rules are that alignment is the minimum
of 4-bytes and the type length. As pointers are 4-bytes on these
targets, then (assuming method and members pointers are also 4-bytes)
there should be no change to the alignment after this patch.
For i386 the gdbarch alignment hook overrides for some INT and FLOAT
types only. For method and member pointers we align on the type size
still, so there should be no change to the alignment after this patch.
I tested this on x86-64 GNU Linux with no regressions.
gdb/ChangeLog:
* gdbtypes.c (type_align): Allow alignment of TYPE_CODE_METHODPTR
and TYPE_CODE_MEMBERPTR to be overridden by the gdbarch.

Fix leaks of 'per program space' and 'per inferior' ada task data.
Valgrind reports leaks such as the below.
Fix these leaks by changing ada_tasks_pspace_data_handle
and ada_tasks_inferior_data_handle to use the 'with_cleanup' register variant.
Tested on debian/amd64 natively and under Valgrind.

Fix pager bugs with style output
I believe this fixes all the pager output problems with styling that
Philippe pointed out, plus at least one more. The patch is somewhat
hard to reason about, so you may wish to give it a try. Even writing
the tests was hard.
This removes the style caching, because it was difficult to keep the
style cache correct in all cases. Since this would cause more style
escapes to be emitted, instead it changes fputs_styled to try to avoid
unnecessary changes.
Another bug was that the wrap buffer was not flushed in the case where
wrap_column==0. In the old (pre-patch series) code, characters were
directly emitted in this case; so flushing the wrap buffer here
restores this behavior.
On error the wrap buffer must be emptied. Otherwise, interrupting
output can leave characters in the buffer that will be emitted later.
As discussed on gdb-patches, this fixes the ada-lang.c problem where
filtered and unfiltered printing were mixed. Now user_select_syms
uses filtered printing, which is what its callees were already doing.
Finally, it was possible for source line highlighting to be garbled
(and invalid escape sequences emitted) if the pager was invoked at the
wrong spot. To fix this, the patch arranges for source line escapes
to always be emitted as a unit.

the same as integers and enums, rather than returning zero,
which means for this function that it could not determine its

(Ada) fix GDB crash printing packed array
Trying to print a packed array sometimes leads to a crash (see
attached testcase for an example of when this happens):
| (gdb) p bad
| [1] 65571 segmentation fault gdb -q foo
Variable "bad" is declared in the debug information as an array where
the array's type name has an XPnnn suffix:
| .uleb128 0xc # (DIE (0x566) DW_TAG_typedef)
| .long .LASF200 # DW_AT_name: "pck__t___XP1"
| [loc info attributes snipped]
| .long 0x550 # DW_AT_type
| .byte 0x1 # DW_AT_alignment
The signals to GDB that the debugging information follows a GNAT encoding
used for packed arrays, and an in order to decode it, we need to find
the type whose name is the same minus the "___XPnnn" suffix: "pck__t".
For that, we make a call to ada-lang.c::standard_lookup, which is
a simple function which essentially does:
| /* Return the result of a standard (literal, C-like) lookup of NAME in
| given DOMAIN, visible from lexical block BLOCK. */
|
| [...]
| sym = lookup_symbol_in_language (name, block, domain, language_c, 0);
Unfortunately for us, while the intent of this call was to perform
an exact-match lookup, in our case, it returns ... type pck__t___XP1
instead! In other words, it finds itself back. The reason why it finds
this type is a confluence of two factors:
(1) Forcing the lookup into language_c currently does not affect
how symbol matching is done anymore, because we look at the symbol's
language to determine which kind of matching should be done;
(2) The lookup searches the local context (via block) first, beforei
doing a more general lookup. And looking at the debug info for
the main subprogram, we see that type "pck__t" is not declared
there, only in the debug info for pck.ads. In other words,
there is no way that we accidently find "pck__t" by random chance.
I believe Pedro added a new function called ada_lookup_encoded_symbol
for that specific purpose, so I started by replacing the lookup
by language above by this. Unfortunately, still no joy.
This was because, even though ada_lookup_encoded_symbol puts angle-
brackets around the search name to signal that we want a verbatim
search, we end up losing that information in the function called
to compare a symbol with the search name:
| static bool
| do_full_match (const char *symbol_search_name,
| const lookup_name_info &lookup_name,
| completion_match_result *comp_match_res)
| {
| return full_match (symbol_search_name, ada_lookup_name (lookup_name));
^^^^^^^^^^^^^^^
|
<=> lookup_name.m_ada.m_encoded_name
(no angle brackets)
The way I fixed this was by introducing a new function called
do_exact_match, and then adjust ada_get_symbol_name_matcher to
return that function when seeing that we have a verbatim non-wild-match
search.
As it happens, this fixes an incorrect test in gdb.ada/homony.exp,
where we were inserting a breakpoint on a symbol using the angle-brackets
notation, and got 2 locations for that breakpoint...
(gdb) b <homonym__get_value>
Breakpoint 1 at 0x4029fc: <homonym__get_value>. (2 locations)
... each location being in a different function:
(gdb) info break
Num Type Disp Enb Address What
1 breakpoint keep y <MULTIPLE>
1.1 y 0x00000000004029fc in homonym.get_value
at /[...]/homonym.adb:32
1.2 y 0x0000000000402a3a in homonym.get_value
at /[...]/homonym.adb:50
(gdb) x /i 0x00000000004029fc
0x4029fc <homonym__get_value+8>: movl $0x1d,-0x4(%rbp)
(gdb) x /i 0x0000000000402a3a
0x402a3a <homonym__get_value__2+8>: movl $0x11,-0x4(%rbp)
Since we used angle-brackets, we shouldn't be matching the second one,
something this patch fixes.

* ada-lang.c (standard_lookup): Use ada_lookup_encoded_symbol
instead of lookup_symbol_in_language

Special-case wildcard requests in ravenscar-thread.c
ravenscar-thread.c intercepts resume and wait target requests and
replaces the requested ptid with the ptid of the underlying CPU.
However, this is incorrect when a request is made with a wildcard
ptid.
This patch adds a special case to ravenscar-thread.c for
minus_one_ptid. I don't believe a special case for process wildcards
is necessary, so I have not added that.
Joel's description explains the bug well:
At the user level, we noticed the issue because we had a test were
we insert a breakpoint one some code which is only run from, say,
CPU #2, whereas we unfortunately resumed the execution after having
stopped somewhere in CPU #1. As a result, we sent an order to resume
CPU #1, which starves CPU #2 forever, because the code in CPU #1
waits for some of the Ada tasks allocated to CPU #2 (and we never
reach our breakpoint either).

C++-ify ravenscar_arch_ops
This turns ravenscar_arch_ops into an abstract base class and updates
all the places where it is used. This is an improvement because it
avoids any possibility of forgetting to set one of the function
pointers. It also makes clear that these functions aren't intended to
be changed dynamically.
This version of the patch removes the prepare_to_store method, as it
is unused, and it is easy enough to add if it is ever needed.

(riscv/ada) fix error when calling functions with range argument
Using the gdb.ada/call_pn.exp testcase, and running it by hand on
riscv64-elf, we get the following error:
(gdb) call pn(55)
Could not compute alignment of type
The problem occurs because the parameter's type is a TYPE_CODE_RANGE,
and that type code is not handled by riscv_type_alignment. So this patch
fixes the issue by handling TYPE_CODE_RANGE the same way we handle other
integral types.

(Windows) remove thread notification for main thread of inferior
This is a followup on a recent patch which, among other things
introduced the exit notification of the main thread in order
to be symetrical with the fact that a thread notification was
emitted before signaling its creation.
This patch takes the opposite approach of removing both creation
and exit notifications for that main thread, which is consistent
with what is done on other platforms such as GNU/Linux for instance.

Try to use the canonical version of a sysroot for debug file links.
Object file paths passed to find_separate_debug_file are always
canonical paths with symbolic links resolved. If a sysroot path
traverses a symbolic link, it will not match the object file paths.
Generate a canonical version of the sysroot directory. If it is
valid, use it instead of gdb_sysroot with child_path to determine if
an object file is under a system root.

Use child_path to determine if an object file is under a sysroot.
This fixes the case where the sysroot happens to end in a trailing
'/'. Note that the path returned from child_path always skips over
the directory separator at the start of the base path, so a separator
must always be explicitly added before the base path.

determine if an object file is under a sysroot.

Add a new function child_path.
child_path returns a pointer to the first component in a child path
that comes after a parent path. This does not depend on trying to
stat() the paths since they may describe remote paths but instead
relies on filename parsing. The function requires that the child path
describe a filename that contains at least one component below the
parent path and returns a pointer to the first component.

Look for separate debug files in debug directories under a sysroot.
When an object file is present in a system root, GDB currently looks
for separate debug files under the global debugfile directories. For
example, if the sysroot is set to "/myroot" and hte global debugfile
directory is set to "/usr/lib/debug", GDB will look for a separate
debug file for "/myroot/lib/libc.so.7" in the following paths:
/myroot/lib/libc.so.7.debug
/myroot/lib/.debug/libc.so.7.debug
/usr/lib/debug//myroot/lib/libc.so.7.debug
/usr/lib/debug/lib/libc.so.7.debug
However, some system roots include a full system installation
including a nested global debugfile directory under the sysroot. This
patch adds an additional check to support such systems. In the
example above the additional path searched is:
/myroot/usr/lib/debug/lib/libc.so.7.debug
To try to preserve existing behavior as much as possible, this new
path is searched last for each global debugfile directory.

* symfile.c (find_separate_debug_file): Look for separate debug
files in debug directories under the sysroot.

Use function_name_style to print Ada and C function names
Note that ada-typeprint.c print_func_type is called with
types representing functions and is also called to print
a function NAME together with its type. In such a case, the function
name will be printed using function name style.
Similarly, c_print_type_1 is called to print a type, optionally
with the name of an object of this type in the VARSTRING arg.
So, c_print_type_1 uses function name style to print varstring
when the type code indicates that c_print_type_1 TYPE is some
'real code'.

Fix splay tree KEY leak detected in GDB test gdb.base/macscp.exp
When a node is removed from a splay tree, the splay tree was
not using the function splay_tree_delete_key_fn to release the key.
This was causing a leak, fixed by Tom Tromey.
This patch fixes another key leak, that happens when a key equal to
a key already present is inserted. In such a case, we have to release
the old KEY.
Note that this is based on the assumption that the caller always
allocates a new KEY when doing an insert.
Also, clarify the documentation about when the release functions are
called.

AArch64: Detect exit from execve syscall
Checking the syscall number when stopped on entry/exit relies on checking
the value in register X8.
However, on exit from an execve syscall, the registers will all be cleared.
Given this is only checked on syscall entry/exit, then a cleared register
state either means execve exit or syscall 0 (io_setup) entry with invalid
parameters and an invalid FR and LR, which in reality should never happen.
Use this to detect execve exit.
Move function to allow use of aarch64_sys_execve enum, and use newer
regcache functions.
Fixes gdb.base/catch-syscall.exp on Aarch64.
gdb/ChangeLog:
* aarch64-linux-tdep.c (aarch64_linux_get_syscall_number): Check

x86: Rewrite NOP generation for fill and alignment
increased MAX_MEM_FOR_RS_ALIGN_CODE to 4095 which resulted in increase
of assembler time and memory usage by 5 times for inputs with many
.p2align directives, which is typical for LTO output. This patch passes
max_bytes to TC_FRAG_INIT so that MAX_MEM_FOR_RS_ALIGN_CODE can be set
as needed and tracked by backend it so that HANDLE_ALIGN can check the
maximum alignment for each rs_align_code frag. Wall time to assemble

(Ada) -var-update crash for variable whose type is a reference to changeable
Consider the following variable, which is a string whose value
is not known at compile time, because it is the return value
from a function call (Get_Name):
A : String := Get_Name;
If one tries to create a varobj for that variable, everything works
as expected:
| (gdb) -var-create a * a
| ^done,name="a",numchild="19",value="[19] \"Some kind of string\"",type="<ref> array (1 .. 19) of character",thread-id="1",has_more="0"
However, try then to request an update, regardless of whether the string
has changed or not, and we get a crash:
| -var-update a
| ~"/[...]/gdb/varobj.c:1379: internal-error: bool install_new_value(varobj*, value*, bool): Assertion `!value_lazy (var->value.get ())' failed.\nA problem internal to GDB has been detected,\nfurther debugging may prove unreliable.\nQuit this debugging session? (y or n) "
When the varobj gets created (-var-create), the expression is evaluated
and transformed into a value. The debugging information describes our
variables as a reference to an array of characters, so our value has
the corresponding type. We then call varobj.c::install_new_value
to store that value inside our varobj, and we see that this function
pretty starts by determining weither our varobj is changeable, via:
| changeable = varobj_value_is_changeable_p (var);
(where 'var' is the varobj we are building, and where the function
varobj_value_is_changeable_p simply dispatches to the Ada version
of this routine: ada_value_is_changeable_p).
At this point, the varobj doesn't have a value, yet, but it does
have a type which was provided by varobj_create a little bit before
install_new_value was called. So ada_value_is_changeable_p uses that
to determine whether or not our type is changeable.
Since our type is a reference to an array, and that the value of
such objects is displayed as if there weren't a reference, it means
that our object is changeable -- in other words, if an element of
the string changes, then the "value" field of the varobj will change
accordingly. But unfortunately, ada_value_is_changeable_p mistakenly
returns false, because it is missing the handling of reference types.
As a consequence of this, install_new_value doesn't feel it is
necessary to fetch the value's contents, as explained by the following
comment inside that function:
/* The new value might be lazy. If the type is changeable,
that is we'll be comparing values of this type, fetch the
value now. Otherwise, on the next update the old value
will be lazy, which means we've lost that old value. */
This means that a lazy value gets installed inside our varobj
as a result of the mistake in ada_value_is_changeable_p.
Another important detail is that, after determining whether
our varobj is changeable or not, it then purposefully removes
the reference layer from our value:
/* We are not interested in the address of references, and given
that in C++ a reference is not rebindable, it cannot
meaningfully change. So, get hold of the real value. */
if (value)
value = coerce_ref (value);
The consequence of those two facts on shows up only later, when
the user requests an update (-var-update). When doing so, GDB
evaluates the expression again into a value which is once more
a reference to a string, and then calls install_new_value again
to install the new value and report any changes. This time around,
the call to...
| changeable = varobj_value_is_changeable_p (var);
... now gets a varobj which has a value, and one which had the reference
layer removed! So, this time, we classify the varobj correctly, and
say it is changeable. And because it is changeable, we then go into
the section of code in install_new_value which checks for changes,
where we need the varobj's value to not be lazy, as explained by
the comment we quoted above. That's what the assertion was about.
This patch fixes the issues by teaching ada_value_is_changeable_p
to ignore reference layers when evaluating a given varobj's type.

* ada-varobj.c (ada_value_is_changeable_p): Add handling of
TYPE_CODE_REF types.

Prior to this patch, this testcase reports 2 unresolved tests

Recent gcc commit b4371b277f1e ("[ARC] Enable init_array support")

Even prior to that, it seems ARC port is the only one with this

binutils: Add new GNU format mode to `size` utility
The size tool currently defaults to berkeley format output. However,
this output format has a weird quirk, read-only data is counted
against the text sections, not the data sections.
The code offers no real explanation for why this is, but I'm reluctant
to change it for two reasons, first, I'm assuming it probably makes
sense in some case that I'm not thinking of (maybe a target where
sections are not marked executable, and so there's no distinction
between read-only data and code), and second, the code has been this
way for at least 20 years, I worry that changing things now might
cause more confusion than it solves.
This commit then introduces a new output format for the size tool,
this new format displays the results in a similar manor to the
berkeley format, but counts read-only data in the data column, and
only executable sections are counted in the text column.
Given that this is a brand new output format I've gone ahead and
simplified things a little, while the berkeley format displays the
total twice, once in decimal and once in hex, the new display format
just displays the total in decimal. Of course, there's still the
'--radix' option which can be used to display all the results in
hexadecimal or octal.
I've called the new format 'gnu', so '--format=gnu' or '-G' are used
to access it.

Arm: Backport hlt to all architectures.
The software trap instruction HLT that was introduced in Armv8-a is used
as the semihosting trap instruction in AArch64. In order to allow systems
configured to run AArch64 code to also run AArch32 with semihosting it was
decided that AArch32 should also use HLT in the case of the "mixed mode"
environment. This requires that HLT also be backported to all earlier
architectures. The instruction is in the undefined encoding space earlier
architectures but must trigger a semihosting trap [3].
The Arm Architectural Reference Manual [1] doesn't explicitly mention this
however this is an explicit requirement in the Semihosting-v2 protocol [2].

gdbserver: When attaching, add process before lwps
The recent BP/WP changes for AArch64 swapping the order in add_lwp()
so that the process was added before the lwp. This was due to the lwp
creation requiring the process data.
This also needs changing in linux_attach().
Also add additional checks to make sure cannot attach to the same
process twice. Add test case for this - do this by splitting
attach.exp into distinct pass and error case sections.
Fixes gdb.server/ext-attach.exp on Aarch64.

Make gdb.base/corefile.exp work on terminals with few rows
When creating a pty to spawn a subprocess (such as gdb), Expect
copies the settings of its own controlling terminal, including the
number of rows and columns. If you "make check" on a terminal with just
a few rows (e.g. 4), GDB will paginate before reaching the initial
prompt. In default_gdb_start, used by most tests, this is already
handled: if we see the pagination prompt, we sent \n to continue.
Philippe reported that gdb.base/corefile.exp didn't work in terminals
with just a few rows. This test spawns GDB by hand, because it needs to
check things before the initial prompt, which it couldn't do if it used
default_gdb_start.
In this case I think it's not safe to use the same technique as in
default_gdb_start. Even if we could send a \n if we see a pagination
prompt, we match some multiline regexes in there. So if a pagination
slips in there, it might make the regexes not match and fail the test.
It's also not possible to use -ex "set height 0" or -iex "set height 0",
it is handled after the introduction text is shown.
The simplest way I found to avoid showing the pagination completely is
to set stty_init (documented in expect's man page) to initialize gdb's
pty with a fixed number of rows.
And actually, if we set stty_init in gdb_init, it works nicely as a
general solution applicable to all tests. We can therefore remove the
solution introduced in e882ef3cfc3 ("testsuite: expect possible
pagination when starting gdb") where we matched the pagination prompt
during startup.
gdb/testsuite/ChangeLog:
* lib/gdb.exp (default_gdb_start): Don't match pagination
prompt.
(gdb_init): Set stty_init.

Normalize include guards in gdb
While working on my other scripts to deal with gdb headers, I noticed
that some files were missing include guards. I wrote a script to add
the missing ones, but found that using the obvious names for the
guards ran into clashes -- for example, gdb/nat/linux-nat.h used
"LINUX_NAT_H", but this was also the script's choice for
gdb/linux-nat.h.
So, I changed the script to normalize all include guards in gdb. This
patch is the result.
As usual the script is available here:
https://github.com/tromey/gdb-refactoring-scripts
Tested by rebuilding; I also ran it through "Fedora-x86_64-m64" on the
buildbot.

Fix leak of identifier in macro definition.
Valgrind detects leaks like the following (gdb.base/macscp.exp).
This patch fixes 1 of the 3 leaks (the last one in the list below).
The remaining leaks are better fixed in splay_tree_remove and
splay_tree_insert in libiberty.
Tested on debian/amd64, natively and under valgrind.

Fix 'info proc cmdline' for native FreeBSD processes.
The kern.proc.args.<pid> sysctl returns the argv array as a packed
array of arguments, each null terminated. To construct a complete
command line, the arguments must be joined with spaces by converting
the intermediate nul characters to spaces. Previously only the first
argument was shown in cmdline output. Now, all arguments are shown.

removed check R_X86_64_PC32 relocation against protected symbols in
shared objects. Since elf_x86_64_check_relocs is called after we
have seen all input files, we can check for PC-relative relocations in
elf_x86_64_check_relocs. We should not allow PC-relative relocations
against protected symbols since address of protected function and
location of protected data may not be in the shared object.

Hoist assertion in target_stack::unpush
I noticed that target_stack::unpush first uses the target "t", then
later asserts that it is non-NULL:
strata stratum = t->stratum ();
[...]
gdb_assert (t != NULL);
This is backwards, though, as the assertion must come first.

[PR gdb/23985] Fix libinproctrace.so build
The IPA objects currently may use gnulib replacement apis, which is
wrong: gnulib is not linked into the produced dso and it cannot be
because it is not built with -fPIC -fvisibility=hidden.
The gnulib replacement detection is broken under cross compilation:
for targets other than *-gnu*, replacements are enabled that depend
on execution time detection. This causes unnecessary build failure
when the target has proper support for the replaced api.
This fix tries to undo the replacements, which is tricky because the
gnulib headers are still used for various compile time fixups and
there is no simple knob in gnulib to only turn the replacements off.
Without this workaround gdb fails to cross build to non-gnu targets:
ld: tracepoint-ipa.o: in function `gdb_agent_helper_thread(void*)':
gdb/gdbserver/tracepoint.c:7221: undefined reference to `rpl_strerror'
...

Release the GIL while running a gdb command or expression
PR python/23615 points out that gdb.execute_gdb_command does not
release the Python GIL. This means that, while the gdb command is
running, other Python threads do not run.
This patch solves the problem by introducing a new RAII class that can
be used to temporarily release and then re-acquire the GIL, then puts
this into the appropriate places in execute_gdb_command and
gdbpy_parse_and_eval.
This does not include a test case, because after some research I could
not find a way to write one that was not racy.

Fix GCC9 warning on elf32-arm.c:elf32_arm_final_link_relocate
Fedora Rawhide has just switched to GCC9, and now GDB doesn't compile
because of a BFD warning:
BUILDSTDERR: ../../bfd/elf32-arm.c: In function 'elf32_arm_final_link_relocate':
BUILDSTDERR: ../../bfd/elf32-arm.c:10907:10: error: absolute value function 'labs' given an argument of type 'bfd_signed_vma' {aka 'long long int'} but has parameter of type 'long int' which may cause truncation of value [-Werror=absolute-value]
BUILDSTDERR: 10907 | value = labs (relocation);
BUILDSTDERR: | ^~~~
You can take a look at the full build log here:
https://kojipkgs.fedoraproject.org//work/tasks/4828/32174828/build.log
The fix is (apparently) simple: instead of using 'labs', we should use
'llabs', since we're passing a 'bfd_signed_vma' to it, which is at
least a 'long long int', as far as I have checked. This is what this
patch does.

gdbserver: When attaching, add process before lwps
The recent BP/WP changes for AArch64 swapping the order in add_lwp()
so that the process was added before the lwp. This was due to the lwp
creation requiring the process data.
This also needs changing in linux_attach().
Fixes gdb.server/ext-attach.exp on Aarch64.

tests - now they are no longer racy it'll be easier to spot. Also

AArch64: Update encodings for stg, st2g, stzg and st2zg.
This patch is part of a series of patches to introduce a few changes to the
Armv8.5-A Memory Tagging Extension. This patch updates the st*g instructions
to use a previously reserved field for a new register operand. Thus the
new versions of the instructions are as follows:
- STG Xt, [<Xn|SP>, #<simm>]
- STG Xt, [<Xn|SP>, #<simm>]!
- STG Xt, [<Xn|SP>], #<simm>
- STZG Xt, [<Xn|SP>, #<simm>]
- STZG Xt, [<Xn|SP>, #<simm>]!
- STZG Xt, [<Xn|SP>], #<simm>
- ST2G Xt, [<Xn|SP>, #<simm>]
- ST2G Xt, [<Xn|SP>, #<simm>]!
- ST2G Xt, [<Xn|SP>], #<simm>
- STZ2G Xt, [<Xn|SP>, #<simm>]
- STZ2G Xt, [<Xn|SP>, #<simm>]!
- STZ2G Xt, [<Xn|SP>], #<simm>

target_pass_signals/target_program_signals: Use gdb::array_view
This replaces the pointer and length parameters of target_pass_signals
and target_program_signals with a gdb::array_view parameter, and fixes
the fallout.
In infrun.c, the signal_stop, signal_print, signal_program,
signal_catch, signal_pass globals are currently pointers to
heap-allocated memory. I see no point in that, so I converted them to
arrays. This allows simplifying the calls to
target_pass_signals/target_program_signals, since we can pass the
array directly, which can implicitly convert to gdb::array_view.

AArch64 AAPCS: Ignore static members
Static members in C++ structs are global data and therefore not part of the
list of struct members considered for passing in registers.
Note the corresponding code in GCC (from which the GDB AAPCS code is based)
does not have any static member checks due to the static members not being
part of the struct type at that point.
Extend gdb.base/infcall-nested-structs.exp to test structs with static
members when compiled for C++. XFAIL more cases for x86_64 (see gdb/24104).
For completeness, ensure some test cases have both empty structures and
static members.
Also fixes gdb.dwarf2/dw2-cp-infcall-ref-static.exp.

Use forward_scope_exit for scoped_finish_thread_state
This reimplements the manually-written scoped_finish_thread_state
class as a forward_scope_exit instantiation. forward_scope_exit has
the same interface as scoped_finish_thread_state, so nothing else has
to change.
A forward_scope_exit is preferred over make_scope_exit here because
infrun.c:normal_stop needs to wrap scoped_finish_thread_state in a
gdb::optional. Since we need the type there, might as well use it
everywhere.

commit 5b9b3e53a68f4568dc0b6907e34e763a6c3dd145
Author: Pedro Alves <palves@redhat.com>
Date: Wed Jan 23 18:58:29 2019 +0000
Introduce forward_scope_exit
This adds a template that can be used to automatically instantiate
scope_exit-like types that wrap some cleanup function. The
instantiated type has a ctor that has the same interface as the
wrapped function. While the "magic" is just straight C++11, the
intended use is via the FORWARD_SCOPE_EXIT macro, which is a minimal
macro that avoids spelling out the wrapped function name more than
once:
void some_function (int foo, object *bar);
using some_function_fce = FORWARD_SCOPE_EXIT (some_function);
some_function_fce cleanup (some_int, some_obj_ptr);
The above runs:
some_function (some_int, some_obj_ptr);
at scope exit.
This is mainly useful as opposed to a simpler SCOPE_EXIT when you need
to:
- cancel the scope_exit, in which case you need the object's name
- wrap the scope_exit in a gdb::optional, in which case you need the
scope_exit's type in advance.
More details in the code comments.

Author: Pedro Alves <palves@redhat.com>
Date: Wed Jan 23 18:58:29 2019 +0000
Introduce scope_exit
This add a new template class scope_exit. scope_exit is a
general-purpose scope guard that calls its exit function at the end of
the current scope. A scope_exit may be canceled by calling the
"release" method. The API is modeled on P0052R5 - Generic Scope Guard
and RAII Wrapper for the Standard Library, which is itself based on
Andrej Alexandrescu's ScopeGuard/SCOPE_EXIT.
The main advantage of scope_exit is avoiding writing single-use RAII
classes and its boilerplate. Following patches will remove a few of
such classes.
There are two forms available:
- The "make_scope_exit" form allows canceling the scope guard. Use
it like this:
auto cleanup = make_scope_exit ( <function, function object, lambda> );
...
cleanup.release (); // cancel
- If you don't need to cancel the guard, you can use the SCOPE_EXIT
macro, like this:
SCOPE_EXIT { /* any code you like here. */ }
Note: scope_exit instances do not allocate anything on the heap.

Fix leak in splay-tree
Philippe Waroquiers noticed a memory leak in gdb, which he tracked
down to a bug in splay-tree. splay_tree_remove does not call the
`delete_key' function when it removes the old node; but it should.
I looked at every splay tree in GCC and there is only one that passes
a non-NULL delete function -- the one in lto.c. That file does not
call splay_tree_remove. So, I think this is safe to check in.
I re-ran the LTO tests to double check.
libiberty/
* splay-tree.c (splay_tree_remove): Delete the key if necessary.

AArch64 AAPCS: Empty structs have non zero size in C++
When gdb.base/infcall-nested-structs.c is complied as C++, the compiler
will not pass structs containing empty structs via float arguments.
This is because structs in C++ have a minimum size of 1, causing padding
in the struct once compiled. The AAPCS does not allow structs with
padding to be passed in float arguments.
Add padding checks to AArch64 and add C++ compile variant to the test.
Some of the tests fail on X86_64. This has been raised as bug gdb/24104.
gdb/ChangeLog:
* aarch64-tdep.c (aapcs_is_vfp_call_or_return_candidate_1): Check
for padding.

Testsuite: Ensure stack protection is off for GCC
Using -fstack-protector-strong will cause GDB to break on the wrong line
when placing a breakpoint on a function. This is due to inadequate dwarf
line numbering, and is being tracked by the GCC bug
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=88432
GCC (and Clang) provided by Debian/Ubuntu default to stack protector
being enabled.
Ensure that when running the GDB testsuite, stack protector is always
turned off for GCC 4.1.0 (when stack protector was added) and above.
Ensure that this does not cause infinite recursion due to
test_compiler_info having to compile a file itself.
Add a test to explicitly test breakpoints with various levels of stack
protection on both GCC and Clang, with xfail for the known errors.
Restore change in ovldbreak.exp which worked around the issue.

2019-01-18 Alan Hayward <alan.hayward@arm.com>
* gdb.base/stack-protector.c: New test.
* gdb.base/stack-protector.exp: New file.
* gdb.cp/ovldbreak.exp: Only allow a single break line.
* lib/gdb.exp (get_compiler_info): Use getting_compiler_info
option.
(gdb_compile): Remove stack protector for GCC and prevent
recursion.

Arm: Clean up PE GAS testsuite correct THUMB tests.
The PE targets don't support mapping symbols and so the disassembler is unable
to correctly output thumb instructions when the input was thumb.
So for testcases that only have thumb output, I have copied them and skipped the
ones for which auto-detection is supposed to work on PE, and added a new one
that will force thumb output. This so that the tests still check the mapping
symbols.
For the tests that switch between thumb and arm in one file I just skip them
entirely on PE targets.
This cleans up the PE GAS testsuite.

* sim-arange.c: eliminate DEFINE_NON_INLINE_P
commit c24bdb023c8e1fa969d6eb945059fa8ed0d490c7
Author: Keith Seitz <keiths@redhat.com>

Introduce dwarf2_cu::get_builder
This patch is an attempt to deal with a variety of bugs reported where
GDB segfaults attempting to access a dwarf2_cu's builder. In certain
circumstances, this builder can be NULL. This is especially common
when inheriting DIEs via inlined subroutines in other CUs. The test
case demonstrates one such situation reported by users. See gdb/23773,
rhbz1638798, and dups for other concrete examples.
The approach taken here is to save the ancestor CU into the dwarf2_cu of
all CUs with DIEs that are "imported." This can happen whenever
follow_die_offset and friends are called. This essentially introduces a
chain of CUs that caused the importation of a DIE from a CU. Whenever
a builder is requested of a CU that has none, the ancestors are searched
for the first one with a builder.
A design side effect of this is that the builder can now only be
accessed by getter and setter methods because the builder itself
is private.
The bulk of the patch is relatively mindless text conversion from
"cu->builder" to "cu->get_builder ()". I've included one test which
was derived from one (of the many) bugs reported on the issue in both
sourceware and Fedora bugzillas.

doc: Add table of MI versions
This patch adds a table summarizing the history or MI versions:
- The version number
- Which GDB version introduced it
- Breaking changes compared to the previous version
The goal of the table is to help writers of front ends know which
version of MI they can use with a given GDB version. It will also help
them update their code to work against a newer MI version.
Right now, we just have 1 and 2, but we expect to add an entry for 3
soon. I did a bit of archelogy and reverse engineering of the code to
come up with the breaking changes for MI 2.
I did some changes to the text around it, some things that I thought
needed to be clarified, seemed a bit dated or seemed just wrong
(especially "Apart from mi0, new versions of @value{GDBN} will not
support old versions of MI").

MI versions. Update text around it.

Fix placement of output in TUI mode
The fix for PR tui/28819 regressed gdb command output a bit. In

[PowerPC] Aliases for vector registers
This patch defines pseudo-registers "v0" through "v31" as aliases that
map to the corresponding raw "vr0" through "vr31" vector registers for
Power.
The motivation behind this is that although GDB defines these
registers as "vrX", the disassembler prints them as "vX", e.g. as the
operands in instructions such as "vaddubm v2,v1,v1". This can be
confusing to users trying to print out the values of the operands
while inspecting the disassembled code.
The new aliases are made not to belong to any register group, to avoid
duplicated values in "info register vector" and "info register all".
The arch-specific rs6000_pseudo_register_reggroup_p function had
previously been removed since the other pseudo-registers could have
their groups inferred by their type. It restored with this patch to
handle the aliases. Membership for the other pseudo-registers is
still determined using the default function.
A new tests checks that GDB prints the expected values of vector
registers after they are filled by the inferior, by using both the raw
names and the aliases. Two other existing tests are modified to also
test the aliases.

how the tdep->num_regs and tdep->num_pseudo_regs are calculated, but
didn't update these numbers in the gdbarch for the xtensa-linux target.
As a result xtensa-linux-gdb behaves as xtensa-elf-gdb and cannot

expand a bit the in-GDB help for the "catch exception" help text
One of our users remarked that the help doesn't mention the fact that
the "catch exception" supports the special argument "unhandled" to catch
exceptions which do not have a handler. This patch changes the output
of...
| (gdb) help catch exception
| Catch Ada exceptions, when raised.
| With an argument, catch only exceptions with the given name.
... to ...
| (gdb) help catch exception
| Catch Ada exceptions, when raised.
| Usage: catch exception [ ARG ]
|
| Without any argument, stop when any Ada exception is raised.
| If ARG is "unhandled" (without the quotes), only stop when the exception
| being raised does not have a handler (and will therefore lead to the task's
| termination).
| Otherwise, the catchpoint only stops when the name of the exception being
| raised is the same as ARG.

Finally, we can remove dw2_add_symbol_to_list since the wrapper function

symbols of multiple languages, negating the need for the assertion
entirely.

This patch builds on the previous by enabling the `new' multidictionary

with "mdict_" and similar transformations.
A word of warning, even with the use of multidictionaries, the code
still does not satisfactorily fix the reported problems with gdb/23712

gdb/23712: Introduce multidictionary's
gdb/23712 is a new manifestation of the now-infamous (at least to me)
symtab/23010 assertion failure (DICT_LANGUAGE == SYMBOL_LANGAUGE).
An example of the problem (using test case from symtab/23010):
Reading symbols from /home/rdiez/rdiez/arduino/JtagDue/BuildOutput/JtagDue-obj-release/firmware.elf...done.
(gdb) p SysTick_Handler
dwarf2read.c:9715: internal-error: void dw2_add_symbol_to_list(symbol*, pending**): Assertion `(*listhead) == NULL || (SYMBOL_LANGUAGE ((*listhead)->symbol[0]) == SYMBOL_LANGUAGE (symbol))' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
This assertion was added specifically to catch this condition (of adding
symbols of different languages to a single pending list).
The problems we're now seeing on systems utilizing DWARF debugging seem to
be caused by the use of LTO, which adds a CU with an artificial DIE of
language C99 which references DIEs in other CUs of language C++.
Thus, we create a dictionary containing symbols of C99 but end up
stuffing C++ symbols into it, and the dw2_add_symbol_to_list triggers.
The approach taken here to fix this is to introduce multi-language
dictionaries to "replace" the standard, single-language dictionaries
used today.
Note to reviewers: This patch introduces some temporary functions to
aide with review. This and other artifacts (such as "See dictionary.h"
which appear incorrect) will all be valid at the end of the series.
This first patch introduces the new multidictionary and its API (which
is, by design, identical to the old dictionary interface). It also
mutates dict_create_hashed and dict_create_linear so that they take
a std::vector instead of the usual struct pending linked list. This will
be needed later on.
This patch does /not/ actually enable multidictionary's. That is left
for a subsequent patch in the series.
I've done exhaustive performance testing with this approach, and I've
attempted to minimize the overhead for the (overwhelmingly) most common
one-language scenario.
On average, a -g3 -O0 GDB (the one we developers use) will see
approximately a 4% slowdown when initially reading symbols. [I've
tested only GDB and firefox with -readnow.] When using -O2, this
difference shrinks to ~0.5%. Since a number of runs with these
patches actually run /faster/ than unpatched GDB, I conclude that
these tests have at least a 0.5% error margin.
On our own gdb.perf test suite, again, results appear to be pretty
negligible. Differences to unpatched GDB range from -7.8% (yes,
patched version is again faster than unpatched) to 27%. All tests
lying outside "negligible," such as the 27% slowdown, involve a total
run time of 0.0007 (or less) with smaller numbers of CUs/DSOs (usually 10
or 100). In all cases, the follow-up tests with more CUs/DSOs is never
more than 3% difference to the baseline, unpatched GDB.
In my opinion, these results are satisfactory.

Fix tracepoint.c:parse_tracepoint_definition leak (and one more)
Coverity points out that gdb/tracepoint.c:parse_tracepoint_definition
can leak 'cond' in this line:
cond = (char *) xmalloc (2 * xlen + 1);
That can leak because we're in a loop and 'cond' may have already been
xmalloc'ed into in a previous iteration. That won't normally happen,
because we don't expect to see a tracepoint definition with multiple
conditions listed, but, it doesn't hurt to be pedantically correct,
in case some stub manages to send something odd back to GDB.
At first I thought I'd just replace the xmalloc call with:
cond = (char *) xrealloc (cond, 2 * xlen + 1);
and be done with it. However, my pedantic self realizes that
warning() can throw as well (due to pagination + Ctrl-C), so I fixed
it using gdb::unique_xmalloc_ptr instead.
While doing this, I noticed that these vectors in struct uploaded_tp:
std::vector<char *> actions;
std::vector<char *> step_actions;
hold heap-allocated strings, but nothing is freeing the strings,
AFAICS.
So I ended up switching all the heap-allocated strings in uploaded_tp
to unique pointers. This patch is the result of that.
I also wrote an alternative, but similar patch that uses std::string
throughout instead of gdb::unique_xmalloc_ptr, but in the end reverted
it because the code didn't look that much better, and I kind of
dislike replacing pointers with fat std::string's (3 or 4 times the
size of a pointer) in structures.

Fix leak in mdebugread.c
Coverity points out that all the "continue;" statements in the switch
case in parse_partial_symbols leak STABSTRING. This is because we
only release STABSTRING at the end of the scope, with:
if (stabstring
&& stabstring != debug_info->ss + fh->issBase + sh.iss)
xfree (stabstring);
but that bit of code is skipped if a case in the switch statement ends
with "continue".
Fix this by using gdb::unique_xmalloc_ptr to manage the heap-allocated
version of 'stabsstring'.
I don't know how to test this.

gdb: Improve scoped_switch_fork_info class
After committing this patch I got this feedback:
https://sourceware.org/ml/gdb-patches/2019-01/msg00181.html
This patch makes the constructor of scoped_switch_fork_info explicit,
and wraps the core of the destructor in a TRY/CATCH block.
I've run this through the testsuite on X86-64/GNU Linux, however, this
code is not exercised, so this patch is untested.

* linux-fork.c (scoped_switch_fork_info)
<scoped_switch_fork_info>: Make explicit.

Move psymtabs to their own obstack
Previously, the psymtab obstack was just a pointer to the objfile
obstack. This patch changes psymtabs to use their own obstack,
instead. A gdb::optional is used to avoid unnecessary allocation when
the obstack is not needed.
After this patch, the psymtab code lifetime model is that, in the core
psymtab code, objects allocated on the psymtab obstack may point to
other such objects, or to objects on the per-BFD obstack -- but never
to the objfile obstack.
Note however that this invariant is only obeyed the core psymtab code,
and even there not quite fully: there is still a link from the psymtab
to the full symtab.
Symbol readers are free to work however they like; and in particular,
even after this patch, in practice all symbol readers violate this
invariant via the read_symtab_private field.

Make psymtab_storage::free_psymtabs private
This adds a new psymtab allocation method to psymtab_storage and
changes the free_psymtabs member to be private. While not strictly
necessary, this seems like a decent cleanup, and also makes it simpler
to move psymtabs off of obstacks entirely, should that prove
desirable.

Introduce objfile::reset_psymtabs
This introduces a new method, objfile::reset_psymtabs, and changes
reread_symbols to use it. This method simply destroys the existing
partial symbols and recreates the psymtab_storage object.
This patch fixes a latent bug -- namely, that reread_symbols should
clear objfile::psymbol_map, but does not. I can submit that
separately if you'd prefer.

Introduce class psymtab_storage
This introduces a new psymtab_storage class, which holds all
psymbol-related objects that are independent of the objfile. (This
latter contraint explains why psymbol_map was not moved; though this
could still be done with some work.)
This patch does not yet change where psymtab allocation is done --
that comes later. This just wraps everything in a single object to
make further transformations simpler.
Note that a shared_ptr is used to link from the objfile to the
psymtab_storage object. The end goal here is to allow a given symbol
reader to simply attach to the psymtab_storage object to the BFD, then
reuse it in later invocations; shared_ptr makes this simple to reason
about.

gdb: Remove support for old mangling schemes
An upcoming sync with gcc's libiberty [1] will remove support for old
mangling schemes (GNU v2, Lucid, ARM, HP and EDG). It will remove the
cplus_demangle_opname function, so we need to get rid of its usages in
GDB (it's a GNU v2 specific function).
I think the changes are mostly relatively obvious, some hacks that were
necessary to support overloaded operators with GNU v2 mangling are not
needed anymore.
The change in stabsread.c is perhaps less obvious. I think we could get
rid of more code in that region that is specific to old mangling
schemes, but I chose to do only the minimal changes required to remove
the cplus_demangle_opname uses. There is also a detailed comment just
above that explaining how GNU v2 and v3 mangled symbols are handled, I
decided to leave it as-is, since I wasn't sure which part to remove,
change or leave there.

gdb: Avoid signed integer overflow when printing source lines
When printing source lines with calls to print_source_lines we need to
pass a start line number and an end line number. The end line number
is calculated by calling get_lines_to_list and adding this value to
the start line number. For example this code from list_command:
print_source_lines (cursal.symtab, first,
first + get_lines_to_list (), 0);
The problem is that get_lines_to_list returns a value based on the
GDB setting `set listsize LISTSIZE`. By default LISTSIZE is 10,
however, its also possible to set LISTSIZE to unlimited, in which
case get_lines_to_list will return INT_MAX.
As the parameter signature for print_source_lines is:
void print_source_lines (struct symtab *, int, int,
print_source_lines_flags);
and `first` in the above code is an `int`, then when LISTSIZE is
`unlimited` the above code will result in signed integer overflow,
which is undefined.
The solution in this patch is a new class source_lines_range that can
be constructed from a single line number and a direction (forward or
backward). The range is then constructed from the line number and the
value of get_lines_to_list.
gdb/ChangeLog:
* cli/cli-cmds.c (list_command): Pass a source_lines_range to
print_source_lines.
* source.c (print_source_lines_base): Update line number check.

gdb/testsuite: Remove interactive prompt case from mi_gdb_test
I noticed that when running this test:
make check-gdb RUNTESTFLAGS="--target_board=native-gdbserver gdb.mi/mi-break.exp"
I would occasionally see some UNRESOLVED test results like this:
(gdb)
PASS: gdb.mi/mi-break.exp: mi-mode=separate: breakpoint at main
Expecting: ^(kill[
]+)?(.*[
]+[(]gdb[)]
[ ]*)
kill
&"kill\n"
~"Kill the program being debugged? (y or n) [answered Y; input not from terminal]\n"
=thread-group-exited,id="i1"
ERROR: Got interactive prompt.
UNRESOLVED: gdb.mi/mi-break.exp: mi-mode=separate:
The problem appears to be that the expect buffer fills up to include
the '(y or n)' prompt without including the following lines.
The pattern supplied by the outer test script is looking for the
following lines. As the following lines are not present then expect
matches on the interactive prompt case rather than the case for the
user supplied pattern.
The problem with this is that we are not really at an interactive
prompt, GDB is providing an answer for us and then moving on. When I
examine a successful run of the test the output from GDB is identical,
the only difference is where expect happens to buffer the output from
GDB.
This patch remove all special handling of the interactive prompt
case. This means that if we ever break GDB and start seeing an
unexpected interactive prompt then tests will rely on a timeout to
fail, instead of having dedicated interactive prompt detection, but
this solves the problem that an auto-answered prompt looks very
similar to an interactive prompt.
With this patch in place I can now leave the following loop running
indefinitely, where before it would fail usually after ~10
iterations.
while make check-gdb RUNTESTFLAGS="--target_board=native-gdbserver gdb.mi/mi-break.exp"; \
do /bin/true; \
done
gdb/testsuite/ChangeLog:
* lib/mi-support.exp (mi_gdb_test): Remove interactive prompt
case.

Fix leak in linespec.c
Valgrind reports a leak in many tests, such as:
==9382== 16 bytes in 1 blocks are definitely lost in loss record 236 of 3,282
==9382== at 0x4C2BE6D: malloc (vg_replace_malloc.c:309)

==9382== by 0x51D16A: xresizevec<linespec_canonical_name> (poison.h:170)
==9382== by 0x51D16A: add_sal_to_sals(linespec_state*, std::vector<symtab_and_line, std::allocator<symtab_and_line> >*, symtab_and_line*, char const*, int) (linespec.c:1041)
==9382== by 0x51E2BF: create_sals_line_offset (linespec.c:2215)
==9382== by 0x51E2BF: convert_linespec_to_sals(linespec_state*, linespec*) (linespec.c:2358)
==9382== by 0x521B5D: convert_explicit_location_to_sals (linespec.c:2473)
Fix leak by xfree-ing self->canonical_names in linespec_state_destructor.
The leak probably appeared with the patch 'Remove cleanup from linespec.c',
as there was a cleanup to xfree canonical_names before the patch.
Tested on Debian/amd64, native and under valgrind.

Fix build failure with macOS bison
PR gdb/24060 points out a compilation failure of the C, Fortran and Pascal
parsers when they are built using the macOS system bison. The bug is a name
clash between the VARIABLE token name and the VARIABLE enumerator in ui-out.h.
This patch renames VARIABLE in c-exp.y, f-exp.y and p-exp.y to DOLLAR_VARIABLE
to avoid the clash. It also renames similar variables in other .y files so
that all languages use the same name.

gdb: Handle requests to print source lines backward
...by which I mean from high line number to low, not, actually
backward character by character!
Commit:
commit 62f29fda90cf1d5a1899f57ef78452471c707fd6
Date: Tue Oct 9 22:21:05 2018 -0600
Highlight source code using GNU Source Highlight
introduced a regression in the test gdb.linespec/explicit.exp, in
which a request is made to GDB to print a reverse sequence of lines,
from +10 to -10 from the current line number. The expected behaviour
is that GDB prints nothing. The above commit changed this so that GDB
now prints:
Line number 32 out of range; /path/to/gdb/testsuite/gdb.linespec/explicit.c has 71 lines.
which is a little confusing.
This commit fixes the regression, and restores the behaviour that GDB
prints nothing.
While I was passing I noticed a call to `back` on a std::string that I
was concerned could be empty if the request for source lines returns
an empty string. I don't know if it would be possible for a request
for lines to return an empty string, I guess it should be impossible,
in which case, maybe this should be an assertion, but adding a `empty`
check, seems like an easy and cheap safety net.
gdb/ChangeLog:
* source.c (print_source_lines_base): Handle requests to print
reverse line number sequences, and guard against empty lines
string.

Highlight source code using GNU Source Highlight
A bug was introduced such that when displaying source code from a file
with lines `\r\n` GDB would print `^M` at the end of each line.
This caused a regression on the test gdb.fortran/nested-funcs.exp,
which happens to have `\r\n` line endings.

run_dump_test source in build directory
Some existing tests build .s and .d files for run_dump_test, using an
absolute #source: line in the .d file. This patch changes that scheme
a little to instead use "#source: ./..." in .d files rather than
"#source: $objdir/...", which is more useful in cases where the .d
file is not generated.
This allows RX gas test files to be built in the build directory,
rather than in a source directory (which might be read-only).

Fix crash in "finish"
PR gdb/28155 notes a crash in "finish" that occurs with a particular
source file compiled by clang.
The bug is the typical gdb problem of a missing call to check_typedef.

get_return_value asserts that the return type is not void, but the
callers were not using check_typedef first.

GDB crash re-running program on Windows (native)
Running any program twice on Windows current results in GDB crashing:
$ gdb -q any_program
(gdb) run
$ gdb dummy -batch -ex run -ex run
[New Thread 684960.0xe5878]
[New Thread 684960.0xd75ac]

[Thread 684960.0xc1f50 exited with code 0]
[Inferior 1 (process 684960) exited normally]
(gdb) run
Segmentation fault
The crash happens while processing the CREATE_PROCESS_DEBUG_EVENT
for the second run; in particular, we have in get_windows_debug_event:
| case CREATE_PROCESS_DEBUG_EVENT:
| [...]
| if (main_thread_id)
| windows_delete_thread (ptid_t (current_event.dwProcessId, 0,
| main_thread_id),
| 0);
The problem is that main_thread_id is the TID of the main thread from
the *previous* inferior, and this code is trying to delete that
thread. The problem is that it is constructing a PTID by pairing
the TID of the previous inferior with the PID of the new inferior.
As a result, when we dig inside windows_delete_thread to see
how it would handle that, we see...
| delete_thread (find_thread_ptid (ptid));
Since the PTID is bogus, we end up calling delete_thread with
a NULL thread_info. It used to be harmless, turning the delete_thread
into a nop, but the following change...
| commit 080363310650c93ad8e93018bcb6760ba5d32d1c
| Date: Thu Nov 22 16:09:14 2018 +0000
| Subject: Per-inferior thread list, thread ranges/iterators, down with ALL_THREADS, etc.
... changed delete_thread to get the list of threads from
the inferior, which itself is now accessed via the given
thread_info. This is the corresponding diff that shows the change:
| - for (tp = thread_list; tp; tpprev = tp, tp = tp->next)
| + for (tp = thr->inf->thread_list; tp; tpprev = tp, tp = tp->next)
As a result of this, passing a NULL thread_info is no longer
an option!
Stepping back a bit, the reason behind deleting the thread late
could be found in a patch from Dec 2003, which laconically explains:
| commit 87a45c96062d658ca83b50aa060a648bf5f5f1ff
| Date: Fri Dec 26 00:39:04 2003 +0000
|
| * win32-nat.c (get_child_debug_event): Keep main thread id around
| even after thread exits since Windows insists on continuing to
| report events against it.
A look at the gdb-patches archives did not provide any additional
clues (https://www.sourceware.org/ml/gdb-patches/2003-12/msg00478.html).
It is not clear whether this is still needed or not. This patch
assumes that whatever isue there was, the versions of Windows
we currently support no longer have it.
With that in mind, this commit fixes the issue by deleting the thread
when the inferior sends the exit-process event as opposed to deleting it
later, while starting a new inferior.
This also restores the printing of the thread-exit notification for
the main thread, which was missing before. Looking at the transcript
of the example shown above, we can see 4 thread creation notifications,
and only 3 notifications for thread exits. Now creation and exit
notifications are balanced.
In the handling of EXIT_THREAD_DEBUG_EVENT, the main_thread_id
check is removed because deemed unnecessary: The main thread was
introduced by a CREATE_PROCESS_DEBUG_EVENT, and thus the kernel
is expected to report its death via EXIT_PROCESS_DEBUG_EVENT.
And finally, because the behavior of delete_thread did change
(albeit when getting a value we probably never expected to receive),
this patch also adds a gdb_assert. The purpose is to provide some
immediate information in case there are other callers that mistakenly
call delete_thread with a NULL thread info. This can be useful
information when direct debugging of GDB isn't an option.
gdb/ChangeLog:
* thread.c (delete_thread_1): Add gdb_assert that THR is not
NULL. Initialize tpprev to NULL instead of assigning it
to NULL on the next statement.
* windows-nat.c (windows_delete_thread): Remove check for
main_thread_id before printing thread exit notifications.
(get_windows_debug_event) <EXIT_THREAD_DEBUG_EVENT>:
Remove thread ID check against main_thread_id.
<CREATE_PROCESS_DEBUG_EVENT>: Remove call to
windows_delete_thread.
<EXIT_PROCESS_DEBUG_EVENT>: Add call to windows_delete_thread.

Use xstrdup in tui_set_source_content
valgrind pointed out that the string copy in tui_set_source_content
was not allocating space for the trailing \0:
==3941== Invalid write of size 1
==3941== at 0x4C3239F: strcpy (vg_replace_strmem.c:512)
==3941== by 0x72036B: strcpy (string_fortified.h:90)

Looking closer, I don't think there's a need to check the line width

Don't build readline/libreadline.a, when --with-system-readline is supplied
https://sourceware.org/bugzilla/show_bug.cgi?id=18632
The bundled libreadline is always built, even if the system is
./configure'd --with-system-readline and the build libreadline.a is not
used.
Proposed patch:
Fix ./configure.ac not to proceed readline/, when --with-system-
readline is provided

Remove a cleanup from target-descriptions.c
This removes a cleanup from target-descriptions.c, by changing it to
use a unique_ptr instead. Note that a deletion adapter is used, even
though target_desc is allocated with new, to avoid moving target_desc
to target-descriptions.h.

Change inferior_to_inferior_object to return a gdbpy_ref
Most callers of inferior_to_inferior_object already use a gdbpy_ref,
so this changes inferior_to_inferior_object to return one. Doing this
revealed that create_thread_object was not correctly handling the case
where inferior_to_inferior_object failed, so this patch fixes this as
well.

Place displaced step data directly in inferior structure
This patch moves the per-inferior data related to displaced stepping to
be directly in the inferior structure, rather than in a container on the
side.
On notable difference is that previously, we deleted the state on
inferior exit, which guaranteed a clean state if re-using the inferior
for a new run or attach. We now need to reset the state manually.
At the same time, I changed step_saved_copy to be a gdb::byte_vector, so
it is automatically freed on destruction (which should plug the leak
reported here [1]).

gdb/ChangeLog:
* inferior.h (class inferior) <displaced_step_state>: New field.

Fix leak of struct call_thread_fsm in call_function_by_hand_dummy.
When the call does not complete, the call_thread_fsm allocated
by new_call_thread_fsm is not cleaned up and deleted, which causes
the following leak e.g. in gdb.base/callfuncs.exp:
==29263== 560 bytes in 7 blocks are definitely lost in loss record 2,833 of 3,341
==29263== at 0x4C2E0BC: calloc (vg_replace_malloc.c:762)

==29263== by 0x4E67EB: xcnew<call_thread_fsm> (poison.h:122)
==29263== by 0x4E67EB: new_call_thread_fsm (infcall.c:516)
==29263== by 0x4E67EB: call_function_by_hand_dummy(value*, type*, gdb::array_view<value*>, void (*)(void*, int), void*) (infcall.c:1154)
==29263== by 0x4E784E: call_function_by_hand(value*, type*, gdb::array_view<value*>) (infcall.c:693)
==29263== by 0x496111: eval_call(expression*, noside, int, value**, char const*, type*) [clone .isra.5] (eval.c:835)
Fix the leak by similarly doing cleanup/destroy when restoring
previous state machine.
Tested on debian/amd64, natively and under valgrind.

Fix search of debug files for remote debuggee
When using remote debugging server, and when debuggee filename is
inferred via qXfer:exec-file:read request, or sysroot starts with
"target:", this "target:" prefix of filepaths is not treated correctly
during debug file search - it appears in the middle of the looked up
paths.
In the following example, unpatched GDB can't find separate debug files for
neither the executable, nor standard libraries:
$ gdb -ex 'set debug separate-debug-file 1' -ex 'set sysroot target:/' -ex 'set debug-file-directory /usr/lib/debug:/home/j/hide' -ex 'target remote :3333' -ex 'break main' -ex 'continue' -ex 'bt' -ex 'info sharedlibrary' -ex 'set confirm off' -ex 'quit'

Tracing the origin of this file down, I found that it was copied
from GCC's libstdc++-v3 testsuite:
Adapt and integrate string_view tests
https://www.sourceware.org/ml/gdb-patches/2018-04/msg00113.html
Looking at the version in GCC, I found the same issue, so sent

gdb/riscv: Split ISA and ABI features
The goal of this commit is to allow RV64 binaries compiled for the 'F'
extension to run on a target that supports both the 'F' and 'D'
extensions.
The 'D' extension depends on the 'F' extension and chapter 9 of the
RISC-V ISA manual implies that running a program compiled for 'F' on
a 'D' target should be fine.
To support this the gdbarch now holds two feature sets, one represents
the features that are present on the target, and one represents the
features requested in the ELF flags.
The existing error checks are relaxed slightly to allow binaries
compiled for 32-bit 'F' extension to run on targets with the 64-bit
'D' extension.
A new set of functions called riscv_abi_{xlen,flen} are added to
compliment the existing riscv_isa_{xlen,flen}, and some callers to the
isa functions now call the abi functions when that is appropriate.
In riscv_call_arg_struct two asserts are removed, these asserts no
longer make sense. The asserts were both like this:
gdb_assert (TYPE_LENGTH (ainfo->type)
<= (cinfo->flen + cinfo->xlen));
And were made in two cases, when passing structures like these:
struct {
integer field1;
float field2;
};
or,
struct {
float field1;
integer field2;
};
When running on an RV64 target which only has 32-bit float then the
integer field could be 64-bits, while if the float field is 32-bits
the overall size of the structure can be 128-bits (with 32-bits of
padding). In this case the assertion would fail, however, the code
isn't incorrect, so its safe to just remove the assertion.
This was tested by running on an RV64IMFDC target using a compiler
configured for RV64IMFC, and comparing the results with those obtained
when using a compiler configured for RV64IMFDC. The only regressions
I see (now) are in gdb.base/store.exp and are related too different
code generation choices GCC makes between the two targets.
Finally, this commit does not make any attempt to support running
binaries compiled for RV32 on an RV64 target, though nothing in here
should prevent that being supported in the future.

gdbarch. Relax an error check to allow 32-bit abi float to run on
a target with 64-bit float hardware.

Fix 'help set/show style' strange layouts/results.
The layout for 'help set address|variable' is strange, e.g.:
(gdb) help set style address
style address
List of show Address display styling
Configure address colors and display intensity subcommands:
show Address display styling
Configure address colors and display intensity background -- Set the background color for this property
show Address display styling
Configure address colors and display intensity foreground -- Set the foreground color for this property
show Address display styling
Configure address colors and display intensity intensity -- Set the display intensity color for this property
Type "help show Address display styling
Configure address colors and display intensity" followed by show Address display styling
Configure address colors and display intensity subcommand name for full documentation.
Type "apropos word" to search for commands related to "word".
Command name abbreviations are allowed if unambiguous.
(gdb)
The help for 'set style function|filename' gives help for 'Show':
(gdb) help set style filename
Filename display styling
Configure filename colors and display intensity.
List of show style filename subcommands:
show style filename background -- Set the background color for this property
show style filename foreground -- Set the foreground color for this property
show style filename intensity -- Set the display intensity color for this property
The help for 'show style function|filename' is equally strange, as it speaks
about commands, instead of sub commands:
(gdb) help show style filename
Filename display styling
Configure filename colors and display intensity.
List of commands:
background -- Show the background color for this property
foreground -- Show the foreground color for this property
intensity -- Show the display intensity color for this property
Type "help" followed by command name for full documentation.
Type "apropos word" to search for commands related to "word".
Command name abbreviations are allowed if unambiguous.
(gdb)
This patch fixes all this.
Note that the 'set style' and 'show style' have the same prefix_doc:
(gdb) help show style
Style-specific settings
Configure various style-related variables, such as colors
...
(gdb) help set style
Style-specific settings
Configure various style-related variables, such as colors
...
Other similar commands (such as set|show history) have typically
a more specific prefix:
(gdb) help show history
Generic command for showing command history parameters.
...
(gdb) help set history
Generic command for setting command history parameters.
...
This could be fixed by having set_prefix_doc and show_prefix_doc instead of
the single prefix_doc argument to cli_style_option::add_setshow_commands.
That could be improved if deemed better.

Make ANSI terminal escape sequences work in TUI
PR tui/14126 notes that ANSI terminal escape sequences don't affect
the colors shown in the TUI. A simple way to see this is to try the
extended-prompt example from the gdb manual.
Curses does not pass escape sequences through to the terminal.
Instead, it replaces non-printable characters with a visible
representation, for example "^[" for the ESC character.
This patch fixes the problem by adding a simple ANSI terminal sequence
parser to gdb. These sequences are decoded and those that are
recognized are turned into the appropriate curses calls.
The curses approach to color handling is unusual and so there are some
oddities in the implementation.
Standard curses has no notion of the default colors of the terminal.
So, if you set the foreground color, it is not possible to reset it --
you have to pick some other color. ncurses provides an extension to
handle this, so this patch updates configure and uses it when
available.
Second, in curses, colors always come in pairs: you cannot set just
the foreground. This patch handles this by tracking actually-used
pairs of colors and keeping a table of these for reuse.
Third, there are a limited number of such pairs available. In this
patch, if you try to use too many color combinations, gdb will just
ignore some color changes.
Finally, in addition to limiting the number of color pairs, curses
also limits the number of colors. This means that, when using
extended 8- or 24-bit color sequences, it may be possible to exhaust
the curses color table.
I am very sour on the curses design now.
I do not know how to write a test for this, so I did not.

Add output styles to gdb
This adds some output styling to the CLI.
A style is currently a foreground color, a background color, and an
intensity (dim or bold). (This list could be expanded depending on
terminal capabilities.)
A style can be applied while printing. For ui-out, this is done by
passing the style constant as an argument. For low-level cases,
fprintf_styled and fputs_styled are provided.
Users can control the style via a number of new set/show commands. In
the interest of not typing many nearly-identical documentation
strings, I automated this. On the down side, this is not very
i18n-friendly.
I've chose some default colors to use. I think it would be good to
enable this by default, so that when users start the new gdb, they
will see the new feature.
Stylizing is done if TERM is set and is not "dumb". This could be
improved when the TUI is available by using the curses has_colors
call. That is, the lowest layer could call this without committing to
using curses everywhere; see my other patch for TUI colorizing.
I considered adding a new "set_style" method to ui_file. However,
because the implementation had to interact with the pager code, I
didn't take this approach. But, one idea might be to put the isatty
check there and then have it defer to the lower layers.

Change wrap buffering to use a std::string
Currently wrap buffering is implemented by allocating a string that is
the same width as the window, and then writing characters into it.
However, if gdb emits terminal escapes, then these could possibly
overflow the buffer.
To prevent this, change the wrap buffer to be a std::string and update
the various uses.
This also changes utils.c to always emit characters to the wrap
buffer. This simplifies future patches which emit terminal escape
sequences, and also makes it possible for the "echo" and "printf"
commands to be used to emit terminal escapes and have these work in
the TUI.

Fix leak of set/show verbose doc, avoid xfree of static string
In the tests
py-pp-registration/gdb.log
default/gdb.log
foll-fork/gdb.log
setshow/gdb.log
break-interp/gdb.log
Valgrind detects a leak of the doc strings for the set and show verbose cmd.
Here is the stacktrace of the leaked set doc:
==25548== 15 bytes in 1 blocks are definitely lost in loss record 101 of 3,120

==25548== by 0x289CA7: main (gdb.c:32)
The leak is created by top.c set_verbose 'elaborate joke':
the doc string is changed according to the verbosity:
(gdb) help set verbose
Set verbosity.
(gdb) set verbose on
(gdb) help set verbose
Set verbose printing of informational messages.
(gdb)
set_verbose creates the leak as it replaces the string allocated in
the above stacktrace by a static (non translated) string:
...
if (info_verbose)
{
c->doc = "Set verbose printing of informational messages.";
...
Also, this can possibly trigger a call to 'free' of a static string,
as c->doc_allocated is kept true, while the string is not allocated anymore.
This patch:
* fixes the leak by freeing the previous docs if doc_allocated.
* internationalize the messages.
* properly sets doc_allocated to 0 once doc strings are static.

Avoid internal errors when stepping outside 'main' on MinGW
When one steps with "next" past the 'main's 'return' statement
in MinGW programs built by mingw.org's tools, PC lands in a
function whose symbol is not in any symtab. GDB then looks
up the nearest symbol, and should find none, because all those
with addresses below PC are not real functions. Having
unresolved symbols, whose address is zero, in minsyms tricked
GDB into using these bogus symbols, which then caused
assertion violation and internal_error. See the discussion at
https://sourceware.org/ml/gdb-patches/2018-12/msg00176.html
for more details.

PR24015, glibc-2.28 on little-endian mips32 broken
Commit 2bf2bf23da exposed a bug on targets that create common sections
other than the standard ELF SHN_COMMON. If these are output by ld -r,
then their type becomes SHT_PROGBITS unless the target handles them
specially (eg. by elf_backend_special_sections), and if they are
merged into .bss/.sbss by ld -r then that section becomes SHT_PROGBITS.
Worse, if they are output by ld -r, then their size is increased by
bfd_generic_define_common_symbol during final link, which leads to
bogus file contents being copied to output.
For mips, it seems to me that the .scommon section should not be
output for ld -r, but I haven't made that change in this patch.

Translate PyExc_KeyboardInterrupt to gdb "quit"
A while back I typed "info pretty-printers" with a large number of
printers installed, and I typed "q" to stop the pagination. I noticed
that gdb printed a Python exception in this case.
It seems to me that, instead, quitting pagination (or control-c'ing a
Python command generally) should be handled the same way that gdb
normally handles a quit.
This patch implements this idea by changing gdbpy_handle_exception to
treat PyExc_KeyboardInterrupt specially.

Improve gdb.ada/rename_subscript_param.exp by using more unique names.
With old compilers, the test fails because no debug info is generated
for 'B' and GDB finds some 'b' in atnat.h:
(gdb) print b
Multiple matches for b
[0] cancel
[1] b at ../sysdeps/ieee754/dbl-64/atnat.h:106
[2] b at ../sysdeps/ieee754/dbl-64/atnat.h:106
[3] b at ../sysdeps/ieee754/dbl-64/atnat.h:106
> FAIL: gdb.ada/rename_subscript_param.exp: print b before changing its value (timeout)
Avoid the timeout by renaming 'b' to rename_subscript_param_b.
Also, change 'before' to 'after' in the gdb_test message that prints
the value after changing it.
The test still fails with old compilers that do not properly
generate debug info for this renaming:
(gdb) print rename_subscript_param_b
No definition of "rename_subscript_param_b" in current context.
(gdb) FAIL: gdb.ada/rename_subscript_param.exp: print rename_subscript_param_b before changing its value
Note: if the compiler would generate the correct debug info, the test should
succeed with the name B. However, waiting for this fix, changing the name
ensures that the test fails directly, instead of causing a timeout.

Fix gdb.ada/packed_array_assign.exp by using more unique names.
The test gdb.ada/packed_array_assign fails due to conflict between component 'w'
and system.dim.mks.w:
(gdb) print pra := ((x => 2, y => 0, w => 17), pr, (x => 7, y => 1, w => 23))

(gdb) FAIL: gdb.ada/packed_array_assign.exp: print pra := ((x => 2, y => 0, w => 17), pr, (x => 7, y => 1, w => 23))
Also, depending on the compiler version, the component w might be reordered
and placed before components x and y.
So, change the component order in the source, so that both an old

and a new compiler (GNATMAKE Pro 20.0w (20181210-82), based on gcc 8.2.1)
produce the same component order (checked by using -gnatR3s).
So, update to test the new (more unique) names in the source order.

gdb: Allow struct fields named double
The 64-bit RISC-V target currently models the floating point registers
as having the following type:
union riscv_double
{
builtin_type_ieee_single float;
builtin_type_ieee_double double;
}
Notice the choice of names for the fields of this struct, possibly not
ideal choices, as these are not valid field names in C. However, this
type is only ever defined within GDB (or in the target description),
and no restriction seems to exist on the field names in that case.
The problem though is that currently:
(gdb) info registers $ft0
ft0 {float = 0, double = 0} (raw 0x0000000000000000)
(gdb) p $ft0.float
$1 = 0
(gdb) p $ft0.double
A syntax error in expression, near `double'.
We can access the 'float' field, but not the 'double' field. This is
because the string 'double' is handled differently to the string
'float' in c-exp.y.
In both cases the string '$ft0' is parsed as a VARIABLE expression.
In the 'float' case, the string 'float' becomes a generic NAME token
in 'lex_one_token', which then allows the rule "exp '.' name" to match
and the field name lookup to occur.
The 'double' case is different. In order to allow parsing of the type
string 'long double', the 'double' string becomes the token
DOUBLE_KEYWORD. At this point there's no rule to match "exp '.'
DOUBLE_KEYWORD", so we can never lookup the field named 'double'.
We could rename the fields for RISC-V, and maybe that would be the
best solution. However, its not hard to allow for fields named
'double', which is what this patch does.
A new case is added to the 'field_name' rule to match the
DOUBLE_KEYWORD, and create a suitable 'struct stoken'. With this done
the "exp '.' field_name" pattern can now match, and we can lookup the
double field.
With this patch in place I now see this behaviour:
(gdb) info registers $ft0
ft0 {float = 0, double = 0} (raw 0x0000000000000000)
(gdb) p $ft0.float
$1 = 0
(gdb) p $ft0.double
$2 = 0
I've gone ahead and handled INT_KEYWORD, LONG, SHORT, SIGNED_KEYWORD,
and UNSIGNED as well within field_name.
I've added a new test for this functionality.
This change was tested on x86-64 GNU/Linux with no regressions.

gdb/riscv: Prevent buffer overflow in riscv_return_value
The existing code for reading and writing the return value can
overflow the passed in buffers in a couple of situations. This commit
aims to resolve these issues.
The problems were detected using valgrind, here are two examples,
first from gdb.base/structs.exp:
(gdb) p/x fun9()

...
There are a couple of problems with the existing code, that are all
related.
In riscv_call_arg_struct we incorrectly rounded up the size of a
structure argument. This is unnecessary, and caused GDB to read too
much data into the output buffer when extracting a struct return
value.
In fixing this it became clear that we were incorrectly assuming that
any value being placed in a register (or read from a register) would
always access the entire register. This is not true, for example a
9-byte struct on a 64-bit target places 8-bytes in one registers and
1-byte in a second register (assuming available registers). To handle
this I switch from using cooked_read to cooked_read_part.
Finally, when processing basic integer return value types these are
extended to xlen sized types and then passed in registers. We
currently don't handle this type expansion in riscv_return_value, but
we do in riscv_push_dummy_call. The result is that small integer
types (like char) result in a full xlen sized register being written
into the output buffer, which results in buffer overflow. To address
this issue we now create a value of the expanded type and use this
values contents buffer to hold the return value before casting the
value down to the smaller expected type.
This patch resolves all of the valgrind issues I have found so far,
and causes no regressions. Tested against RV32/64 with and without
floating point support.
gdb/ChangeLog:
* riscv-tdep.c (riscv_call_arg_struct): Don't adjust size before
assigning locations.
(riscv_return_value): Take more care not to read/write outside of

Add debug output for recorded minsyms
While discussing this issue:

I added a printf gated by "set debug symtab-create" to be able to
quickly see all minimal symbols recorded by GDB. I thought it would be
useful to have it built-in, for the future. Here's how the output
looks:

Fix various tests to use -no-pie linker flag when needed
Various tests use test code written in i386 / x86_64 assembly that cannot
be used to create PIE executables. Therefore compilation of test programs
failed on systems where the compiler default is to create PIE executable.
The solution is to use -no-pie linker flag, however, such flag may not
(is not) supported by all compilers GDB needs to support (e.g. gcc 4.8).
To handle this, introduce a new flag to gdb_compile - nopie - which
inserts -no-pie linker flag where supported and is no-op where it is
not. By default, -no-pie flag is inserted since most modern compiler do
support it.

Workaround a FreeBSD kernel bug resulting in spurious SIGTRAP events.
The ptrace command PT_LWPINFO to request detailed information about a
stopped thread can return stale signal information from an earlier
stop. Events which are reporting an intercepted signal will always
report the correct information, but signal stops for some other events
such as system call enter/exit events might include stale siginfo from
an earlier signal. In particular, if a thread reports a system call
entry or exit event after previously reporting a single-step or
breakpoint event via SIGTRAP, fbsd_handle_debug_trap believed the
system call event was the previous event and claimed it resulting in a
spurious SIGTRAP event.
True breakpoint and single-step events will never report another event
in the pl_flags member of struct ptrace_lwpinfo. Use this to detect
stale siginfo by requiring pl_flags to have only the PL_FLAG_SI flag
and no other flags before treating a SIGTRAP as a single-step or
breakpoint trap.
gdb/ChangeLog:
* fbsd-nat.c (fbsd_handle_debug_trap): Require pl.pl_flags to
equal PL_FLAG_SI.
(fbsd_nat_target::stopped_by_sw_breakpoint): Likewise.

gdb: Fix "info os <unknown>" command
Running `info os someUnknownOsType` is crashing when gdb is built with
-D_GLIBCXX_DEBUG:
/usr/include/c++/5/debug/vector:439:error: attempt to
access an element in an empty container.
In target_read_stralloc from target.c, the call to
target_read_alloc_1 can return an empty vector, we then call vector::back on
this vector, which is invalid.
This commit adds a check for emptiness before trying to call
vector::back on it. It also adds test to check for `info os <unknown>`
to return the proper error message.
This is a regression in gdb 8.2 and this patch restores the behavior of
previous versions.

Fix compile error with clang 3.8
When compiling with clang 3.8 (default clang version on Debian

Silence them by value-initializing those objects. It's not necessary
with other compilers (later clang versions, gcc), but it shouldn't
hurt either.

Ensure deterministic result order in gdb.ada/info_auto_lang.exp
standard_ada_testfile, standard_test_file and the explicit
csrcfile assignment in info_auto_lang.exp all gives similar pathnames
prefix for a source, such as
/home/philippe/gdb/git/build_binutils-gdb/gdb/testsuite/../../../binutils-gdb/gdb/testsuite/gdb.<something>.
Note that the above pathnames contain ../ which appears when a relative
pathname is used to call configure.
In any case, the gnat compiler normalizes Ada sources path when compiling.
So, the 'Ada' .o object are referencing a pathname such as
/home/philippe/gdb/git/binutils-gdb/gdb/testsuite/gdb.ada/info_auto_lang/proc_in_ada.adb,
while the 'C' .o object still references the not normalized pathname.
As the results of 'info functions | ...' are sorted by pathname first,
the order of the results depends on the comparison between different directories,
leading to results that can change depending on these directories.
=> Ensure the result order is always the same, by normalising the C source file,
which makes the results independent of the way configure is launched.
Tested by running the testcase in 2 different builds, that without normalize
were giving different results.
Note: such 'set csrcfile' is used in 4 other tests mixing Ada and C.
After discussion, it was deemed sufficient to just normalize the pathname
for this test.

gdb: Add default frame methods to gdbarch
Supply default gdbarch methods for gdbarch_dummy_id,
gdbarch_unwind_pc, and gdbarch_unwind_sp. This patch doesn't actually
convert any targets to use these methods, and so, there will be no
user visible changes after this commit.
The implementations for default_dummy_id and default_unwind_sp are
fairly straight forward, these just take on the pattern used by most
targets. Once these default methods are in place then most targets
will be able to switch over.
The implementation for default_unwind_pc is also fairly straight
forward, but maybe needs some explanation.
This patch has gone through a number of iterations:
https://sourceware.org/ml/gdb-patches/2018-03/msg00165.html
https://sourceware.org/ml/gdb-patches/2018-03/msg00306.html
https://sourceware.org/ml/gdb-patches/2018-06/msg00090.html
https://sourceware.org/ml/gdb-patches/2018-09/msg00127.html
and the implementation of default_unwind_pc has changed over this
time. Originally, I took an implementation like this:
CORE_ADDR
default_unwind_pc (struct gdbarch *gdbarch, struct frame_info *next_frame)
{
int pc_regnum = gdbarch_pc_regnum (gdbarch);
return frame_unwind_register_unsigned (next_frame, pc_regnum);
}
This is basically a clone of default_unwind_sp, but using $pc. It was
pointed out that we could potentially do better, and in version 2 the
implementation became:
CORE_ADDR
default_unwind_pc (struct gdbarch *gdbarch, struct frame_info *next_frame)
{
struct type *type;
int pc_regnum;
CORE_ADDR addr;
struct value *value;
pc_regnum = gdbarch_pc_regnum (gdbarch);
value = frame_unwind_register_value (next_frame, pc_regnum);
type = builtin_type (gdbarch)->builtin_func_ptr;
addr = extract_typed_address (value_contents_all (value), type);
addr = gdbarch_addr_bits_remove (gdbarch, addr);
release_value (value);
value_free (value);
return addr;
}
The idea was to try split out some of the steps of unwinding the $pc,
steps that are on some (or many) targets no-ops, and so allow targets
that do override these methods, to make use of default_unwind_pc.
This implementation remained in place for version 2, 3, and 4.
However, I realised that I'd made a mistake, most targets simply use
frame_unwind_register_unsigned to unwind the $pc, and this throws an
error if the register value is optimized out or unavailable. My new
proposed implementation doesn't do this, I was going to end up
breaking many targets.
I considered duplicating the code from frame_unwind_register_unsigned
that throws the errors into my new default_unwind_pc, however, this
felt really overly complex. So, what I instead went with was to
simply revert back to using frame_unwind_register_unsigned. Almost
all existing targets already use this. Some of the ones that don't can
be converted to, which means almost all targets could end up using the
default.
One addition I have made over the version 1 implementation is to add a
call to gdbarch_addr_bits_remove. For most targets this is a no-op,
but for a handful, having this call in place will mean that they can
use the default method. After all this, the new default_unwind_pc now
looks like this:
CORE_ADDR
default_unwind_pc (struct gdbarch *gdbarch, struct frame_info *next_frame)
{
int pc_regnum = gdbarch_pc_regnum (gdbarch);
CORE_ADDR pc = frame_unwind_register_unsigned (next_frame, pc_regnum);
pc = gdbarch_addr_bits_remove (gdbarch, pc);
return pc;
}

[GOLD] Tweak keep_text_section_prefix test for PowerPC64 ELFv1
This test checks code layout by function symbol ordering, but that
doesn't work on powerpc64 ELFv1 where the function symbol is on a
descriptor. A simple work-around is to have nm emit synthetic symbols
marking the code entry point of functions. Since the text segment is
laid out before the data segment, the synthetic symbols will have
lower addresses than function descriptor symbols and be seen first in
nm -n output.
On other targets, nm --synthetic typically emits symbols on plt
entries. Since the testcase doesn't call any of the functions of
interest there shouldn't be plt entries for those functions, so there
should be no potentially confusing extra symbols.

sim: Don't overwrite stored errno in sim_syscall_multi
The host syscall callback mechanism should take care of updating the
errcode within the CB_SYSCALL struct, and we should not be adjusting
the error code once the syscall has completed. We especially, should
not be rewriting the syscall errcode based on the value of errno some
time after running the host syscall, as there is no guarantee that
errno has not be overwritten.
To perform a syscall we call cb_syscall (in syscall.c). To return
from cb_syscall control passes through one of two exit paths these are
labeled FinishSyscall and ErrorFinish and are reached using goto
statements scattered throughout the cb_syscall function.
In FinishSyscall we store the syscall result in 'sc->result', and the
error code is transated to target encoding, and stored in
'sc->errcode'.
In ErrorFinish, we again store the syscall result in 'sc->result', and
fill in 'sc->errcode' by fetching the actual errno from the host with
the 'cb->get_errno' callback.
In both cases 'sc->errcode' will have been filled in with an
appropriate value.
Further, if we look at a specific syscall example, CB_SYS_open, in
this case the first thing we do is fetch the path to open from the
target with 'get_path', if this fails then the errcode is returned,
and we jump to FinishSyscall. Notice that in this case, no host
syscall may have been performed, for example a failure to read the
path to open out of simulated memory can return EINVAL without
performing any host syscall. Given that no host syscall has been
performed, reading the host errno makes absolutely no sense.
This commit removes from sim_syscall_multi the rewriting of
sc->errcode based on the value of errno, and instead relies on the
value stored in the cb_syscall.
sim/common/ChangeLog:
* sim-syscall.c (sim_syscall_multi): Don't update sc->errcode at
this point, it should have already been set in cb_syscall.

gdb/dwarf: Convert some predicates from int to bool
In the dwarf reader we have a set of predicates, these include the
different producer predicates and also some control predicates. The
older ones are declared as integers, while newer ones (added since the
C++ conversion) are bool.
This commit makes them all bool for consistency. There should be no
user visible change after this commit.
gdb/ChangeLog:
* dwarf2read.c (struct dwarf2_cu): Convert the fields 'mark',
'has_loclist', 'checked_producer', 'producer_is_gxx_lt_4_6',
'producer_is_gcc_lt_4_3', 'producer_is_icc_lt_14',
'processing_has_namespace_info' from unsigned int to bool. Update
comments.

AArch64: Fix the gdb build with musl libc
Including asm/sigcontext.h together with libc headers is not valid. In
general linux headers may not work with libc headers, so mixing them
should be avoided, especially when the linux header defines types that
are also exposed in libc headers.
In case of asm/sigcontext.h glibc happens to work because glibc signal.h
directly includes it, but e.g. in musl libc signal.h replicates the
sigcontext.h definitions in an abi compatible way which are in conflict
with the linux definitions when both headers are included.
Since old linux headers or old libc headers may not have the necessary
definitions, gdb has to replicate the definitions it relies on anyway.
Which is fine since all definitions must be ABI stable. For linux apis
that are not available via libc headers, replicating the definitions in
gdb is the most reliable way to use them.
Note: asm/ptrace.h includes asm/sigcontext.h in some versions of linux
headers, which is just as problematic and should be fixed in linux.
gdb/ChangeLog:
* nat/aarch64-sve-linux-ptrace.h: Include signal.h instead of
asm/sigcontext.h.

Factorize killing the children in linux-ptrace.c, and fix a 'process leak'.
Running the gdb testsuite under Valgrind started to fail after 100+ tests,
due to out of memory caused by lingering processes.
The lingering processes are caused by the combination
of a limitation in Valgrind signal handling when using PTRACE_TRACEME
and a (minor) bug in GDB.
The Valgrind limitation is : when a process is ptraced and raises
a signal, Valgrind will replace the raised signal by SIGSTOP as other
signals are masked by Valgrind when executing a system call.
Removing this limitation seems far to be trivial, valgrind signal
handling is very complex.
Due to this valgrind limitation, GDB linux_ptrace_test_ret_to_nx gets
a SIGSTOP signal instead of the expected SIGTRAP or SIGSEGV.
In such a case, linux_ptrace_test_ret_to_nx does an early return, but
does not kill the child (running under valgrind), child stays in a STOP-ped
state.
These lingering processes then eat the available system memory,
till launching a new process starts to fail.
This patch fixes the GDB minor bug by killing the child in case
linux_ptrace_test_ret_to_nx does an early return.
nat/linux-ptrace.c has 3 different logics to kill a child process.
So, this patch factorizes killing a child in the function kill_child.
The 3 different logics are:
* linux_ptrace_test_ret_to_nx is calling both kill (child, SIGKILL)
and ptrace (PTRACE_KILL, child, ...), and then is calling once
waitpid.
* linux_check_ptrace_features is calling ptrace (PTRACE_KILL, child, ...)
+ my_waitpid in a loop, as long as the waitpid status was WIFSTOPPED.
* linux_test_for_tracefork is calling once ptrace (PTRACE_KILL, child, ...)
+ my_waitpid.
The linux ptrace documentation indicates that PTRACE_KILL is deprecated,
and tells to not use it, as it might return success but not kill the tracee.
The documentation indicates to send SIGKILL directly.
I suspect that linux_ptrace_test_ret_to_nx calls both kill and ptrace just
to be sure ...
I suspect that linux_check_ptrace_features calls ptrace in a loop
to bypass the PTRACE_KILL limitation.
And it looks like linux_test_for_tracefork does not handle the PTRACE_KILL
limitation.
Also, 2 of the 3 logics are calling my_waitpid, which seems better,
as this is protecting the waitpid syscall against EINTR.
So, the logic in kill_child is just using kill (child, SIGKILL)
+ my_waitpid, and then does a few verifications to see everything worked
accordingly to the plan.
Tested on Debian/x86_64.

elf: Add PT_GNU_PROPERTY segment type
Linkers group input note sections with the same name into one output
note section with the same name. One output note section is placed in
one PT_NOTE segment. New linkers merge all input .note.gnu.property
sections into one output .note.gnu.property section with a single
NT_GNU_PROPERTY_TYPE_0 note in a single PT_NOTE segment. Since older
linkers treat input .note.gnu.property section as a generic note section
and just concatenate all input .note.gnu.property sections into one
output .note.gnu.property section without merging them, we may
see one or more NT_GNU_PROPERTY_TYPE_0 notes in PT_NOTE segment, which
are invalid.
GNU_PROPERTY_X86_UINT32_VALID was defined to address this issue such
that linker sets the bit for non-relocatable outputs. But it isn't
sufficient:
1. It doesn't cover generic properties.
2. When -mx86-used-note=yes is passed to x86 assembler, the
GNU_PROPERTY_X86_UINT32_VALID bit is set in GNU_PROPERTY_X86_ISA_1_USED
property in object file and older linkers generate invalid
NT_GNU_PROPERTY_TYPE_0 notes with the GNU_PROPERTY_X86_UINT32_VALID bit
set.
I am proposing the following changes:
1. Add PT_GNU_PROPERTY segment type:
# define PT_GNU_PROPERTY (PT_LOOS + 0x474e553)
which covers .note.gnu.property section.
2. Remove GNU_PROPERTY_X86_UINT32_VALID.

Update the FreeBSD system call table to match FreeBSD 12.0.
Add a script to generate the FreeBSD XML system call table from the
sys/sys/syscall.h file in the kernel source tree. For ABI
compatiblity system calls used by older binaries (such as
freebsd11_kevent()), the original system call name is used as an
alias.

branch which is expected to be the file used in 12.0 (head is
currently in code freeze as part of the 12.0 release process).

Add an optional "alias" attribute to syscall entries.
When setting a syscall catchpoint by name, catch syscalls whose name
or alias matches the requested string.
When the ABI of a system call is changed in the FreeBSD kernel, this
is implemented by leaving a compatibility system call using the old
ABI at the existing "slot" and allocating a new system call for the
version using the new ABI. For example, new fields were added to the
'struct kevent' used by the kevent() system call in FreeBSD 12. The
previous kevent() system call in FreeBSD 12 kernels is now called
freebsd11_kevent() and is still used by older binaries compiled
against the older ABI. The freebsd11_kevent() system call can be
tagged with an "alias" attribute of "kevent" permitting 'catch syscall
kevent' to catch both system calls and providing the expected user
behavior for both old and new binaries. It also provides the expected
behavior if GDB is compiled on an older host (such as a FreeBSD 11
host).

gdb: Update test pattern to deal with native-extended-gdbserver
When running the test gdb.base/annota1.exp with:
make check-gdb RUNTESTFLAGS="--target_board=native-extended-gdbserver gdb.base/annota1.exp"
I would see a failure due to some unexpected lines in GDB's output.
The extra lines (when compared with a native run) were about file
transfer from the remote back to GDB.
This commit extends the regexp for this test to allow for these extra
lines, and also splits the rather long regexp up into a list of parts.
With this change in place I see no failures for gdb.base/annota1.exp
when using the native-extended-gdbserver target board, nor with a
native run on X86-64/Linux.

gdb/infcall: Make infcall_suspend_state into a class
I ran into a situation where attempting to make an inferior function
call would trigger an assertion, like this:
(gdb) call some_inferior_function ()
../../src/gdb/regcache.c:310: internal-error: void regcache::restore(readonly_detached_regcache*): Assertion `src != NULL' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
The problem that triggers the assertion is that in the function
save_infcall_suspend_state, we basically did this:
1. Create empty infcall_suspend_state object.
2. Fill fields of infcall_suspend_state object.
The problem is causes is that if filling any of the fields triggered
an exception then the infcall_suspend_state object would be deleted
while in a partially filled in state.
In the specific case I encountered, I had a remote RISC-V target that
claimed in its target description to support floating point registers.
However, this was not true, and when GDB tried to read a floating
point register the remote sent back an error. This error would cause
an exception to be thrown while creating the
readonly_detached_regcache, which in turn caused GDB to try and delete
an infcall_suspend_state which didn't have any register state, and
this triggered the assertion.
To prevent this problem we have two possibilities, either, rewrite the
restore code the handle partially initialised infcall_suspend_state
objects, or, prevent partially initialised infcall_suspend_state
objects from existing. The second of these seems like a better
solution.
So, in this patch, I move the filling in of the different
infcall_suspend_state fields within a new constructor for
infcall_suspend_state. Now, if generating one of those fields fails
the destructor for infcall_suspend_state will not be executed and GDB
will not try to restore the partially saved state.
With this patch in place GDB now behaves like this:
(gdb) call some_inferior_function ()
Could not fetch register "ft0"; remote failure reply 'E99'
(gdb)
The inferior function call is aborted due to the error.
This has been tested against x86-64/Linux native, native-gdbserver,
and native-extended-gdbserver with no regressions. I've manually
tested this against my baddly behaving target and confirmed the
inferior function call is aborted as described above.

gdb/riscv: Handle passing variadic floating point arguments
This commit fixes some test failures in gdb.base/varargs.exp when
running on targets with floating point hardware. Floating point
unnamed (variadic) arguments should be passed in integer registers
according to the abi.
After this commit I see no failures in gdb.base/varargs.exp on 32 or
64 bit targets with floating point hardware.

Fix leaks in all the linux osdata annex transfers + code factorization.
Valgrind reports leaks in all linux osdata annex transfers of linux-osdata.c.
A typical leak (this one is of gdb.base/info-os) is:
==10592== VALGRIND_GDB_ERROR_BEGIN
==10592== 65,536 bytes in 1 blocks are definitely lost in loss record 3,175 of 3,208
==10592== at 0x4C2E273: realloc (vg_replace_malloc.c:826)
==10592== by 0x409B0C: xrealloc (common-utils.c:62)
==10592== by 0x408BC3: buffer_grow(buffer*, char const*, unsigned long) [clone .part.1] (buffer.c:40)
==10592== by 0x5263DF: linux_xfer_osdata_processes(unsigned char*, unsigned long, unsigned long) (linux-osdata.c:370)
==10592== by 0x520875: linux_nat_xfer_osdata (linux-nat.c:4214)
...
The leaks are created because the linux_xfer_osdata_* functions
transfer the ownership of their 'static struct buffer' memory
to their 'static char *buf' local var, but then call buffer_free
instead of xfree-ing buf.
I see no reason why the ownership of the memory has to be transferred
from a local var to another local var, so the fix consists in dropping
the 'static char *buf' and accessing the struct buffer memory where needed.
Also, because this bug was replicated in all functions, and there was
a non neglectible amount of duplicated code, the setup and usage
of the 'static struct buffer' is factorized in a new function
common_getter. The buffer for a specific annex is now a member
of the struct osdata_type instead of being a static var of each
linux_xfer_osdata_* function.
Thanks to this, all the linux_xfer_osdata_* do not have
anymore any logic related to the partial transfer of data: they now
only build the xml data in a struct buffer.
This all removes about 300 SLOC.
Note: git diff/git format-patch shows a lot of differences only due
to space changes/indentation changes.
So, git diff -w helps to look only at the relevant differences.

Fix tid-reuse sometimes blocks for a very long (infinite?) time.
A failure that seems to cause a long/infinite time is the following:
For a not clear reason, tid-reuse.c spawner thread sometimes gets an error:
tid-reuse: /bd/home/philippe/gdb/git/build_moreaa/gdb/testsuite/../../../moreaa/gdb/testsuite/gdb.threads/tid-reuse.c:58: spawner_thread_func: Assertion `rc == 0' failed.
which causes a SIGABRT to be trapped by gdb, and tid-reuse does not reach the
after_count breakpoint:
Thread 2 "tid-reuse" received signal SIGABRT, Aborted.
[Switching to Thread 0x7ffff7518700 (LWP 10368)]
__GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:51
51 ../sysdeps/unix/sysv/linux/raise.c: No such file or directory.
(gdb) FAIL: gdb.threads/tid-reuse.exp: continue to breakpoint: after_count
After that, tid-reuse.exp gets the value of reuse_time, but this one kept its
initial value of -1 (as unsigned) :
print reuse_time
$1 = 4294967295
(gdb) PASS: gdb.threads/tid-reuse.exp: get reuse_time
tid-reuse then dies, and the .exp script continues (with some FAIL)
till it executes:
set timeout [expr $reuse_time * 2]
leading to the error:
(gdb) ERROR: integer value too large to represent as non-long integer

This patch gives a default value of 60, so that if ever something wrong happens
in tid-reuse, then the value retrieved by the .exp script stays in a reasonable
range.
Simon verified the patch by:
"I replaced the pthread_create call with the value 1 to simulate a
failure, and the test succeeds to fail quickly with your patch applied.
Without your patch, I get the infinite hang that you describe."
Compared to V1:
As suggested by Pedro, this version checks the pthread calls return
code (in particular of pthread_create) and reports the failure reason,
instead of just aborting.

This leak is created because a call to td_ta_new allocates some resources
that must be freed with td_ta_delete, and that was missing.
With this patch, the nr of GDB executions leaking during regression tests
decreases further from 566 to 380.
Note that the gdbserver equivalent code is properly calling
td_ta_delete: see thread_db_mourn in thread-db.c.
Tests run natively on debian/amd64, and run under valgrind.

* source.c: Various cosmetic changes.
(forward_search_command): Handle very long source lines correctly.
a buffer with a hard limit was converted to a heap buffer:
@@ -1228,15 +1284,26 @@ forward_search_command (regex, from_tty)
stream = fdopen (desc, FOPEN_RT);
clearerr (stream);
while (1) {
-/* FIXME!!! We walk right off the end of buf if we get a long line!!! */
- char buf[4096]; /* Should be reasonable??? */

+ static char *buf = NULL;
+ register char *p;
+ int cursize, newsize;

+ cursize = 256;
+ buf = xmalloc (cursize);
+ p = buf;
However, reverse_search_command has the exact same problem, and that
wasn't fixed. We still have that "we walk right off" comment...
Recently, the xmalloc above was replaced with a xrealloc, because as
can be seen above, that 'buf' variable above was a static local,
otherwise we'd be leaking. This commit replaces that and the
associated manual buffer growing with a gdb::def_vector<char>. I
don't think there's much point in reusing the buffer across command
invocations.
While doing this, I realized that reverse_search_command is almost
identical to forward_search_command. So this commit factors out a
common helper function instead of duplicating a lot of code.
There are some tests for "forward-search" in gdb.base/list.exp, but
since they use the "search" alias, they were a bit harder to find than
expected. That's now fixed, both by testing both variants, and by
adding some commentary. Also, there are no tests for the
"reverse-search" command, so this commit adds some for that too.

gdb/emacs/dir-locals: Update settings for c++-mode
The current .dir-locals file for GDB causes files that would usually
open in c-mode (for example, files ending in .c) to open in c++-mode.
However, all of the other settings applied for c-mode appear to get
reset when the file is switched over to c++-mode.
For example, we currently say:
(c-mode . ((c-file-style . "GNU")
(mode . c++)
(indent-tabs-mode . t)
(tab-width . 8)
(c-basic-offset . 2)
(eval . (c-set-offset 'innamespace 0))
))
(c++-mode . ((eval . (when (fboundp 'c-toggle-comment-style)
(c-toggle-comment-style 1)))))
So, when we enter c++-mode `indent-tabs-mode` is reset to its global
value, as are all of the other settings listed for c-mode.
This commit copies all of the settings (except the `mode` setting)
from the c-mode list to the c++-mode list.
The emacs documentation doesn't mention that `mode` causes this
resetting behaviour, so, in case this is an emacs bug, I'm using emacs
version 26.1. Having the settings duplicated shouldn't cause any
problems except for a slight maintenance overhead.
gdb/ChangeLog:
* .dir-locals.el: Copy most of the settings from c-mode over to
c++-mode.

Fix a (one shot small) leak in language.c
Valgrind detects the following leak:

==28395== 5 bytes in 1 blocks are definitely lost in loss record 20 of 2,770
==28395== at 0x4C2BE2D: malloc (vg_replace_malloc.c:299)

==28395== by 0x29D837: main (gdb.c:32)
==28395==
==28395== VALGRIND_GDB_ERROR_END
This is a very small leak (1 block/5 bytes), happening only once
per GDB startup as far as I can see. But this fix make the nr of leaking
GDB in the testsuite decreasing from 628 to 566.
It is unclear why a xstrdup-ed value is assigned to 'language'
at initialization time, while a static "auto" string is assigned
as part of the set_language_command.
So, that shows that it is ok to initialize 'language' directly
with "auto".
Also, I cannot find any place where 'language' is xfree-d.
No leak was detected for 'range' and 'case_sensitive', but
similarly, no indication why a static string cannot be assigned.
Regression-tested on debian/x86_64.
Also, full testsuite run under valgrind, less tests leaking,
and no dangling pointer problem detected.

PowerPC @l, @h and @ha warnings, plus VLE e_li
This patch started off just adding the warnings in tc-ppc.c about
incorrect usage of @l, @h and @ha in instructions that don't have
16-bit D-form fields. That unfortunately showed up three warnings in
ld/testsuite/ld-powerpc/vle-multiseg.s on instructions like
e_li r3, IV_table@l+0x00
which was being assembled to
8: 70 60 00 00 e_li r3,0
a: R_PPC_ADDR16_LO IV_table
The ADDR16_LO reloc is of course completely bogus on e_li, which has
a split 20-bit signed integer field in bits 0x1f7fff, the low 11 bit
in 0x7ff, the next 5 bits in 0x1f0000, and the high 4 bits in 0x7800.
Applying an ADDR16_LO reloc to the instruction potentially changes
the e_li instruction to e_add2i., e_add2is, e_cmp16i, e_mull2i,
e_cmpl16i, e_cmph16i, e_cmphl16i, e_or2i, e_and2i., e_or2is, e_lis,
e_and2is, or some invalid encodings.
Now there is a relocation that suits e_li, R_PPC_VLE_ADDR20, which was
added 2017-09-05 but I can't see code in gas to generate the
relocation. In any case, VLE_ADDR20 probably doesn't have the correct
semantics for @l since ideally you'd want an @l to pair with @h or @ha
to generate a 32-bit constant. Thus @l should only produce a 16-bit
value, I think. So we need some more relocations to handle e_li it
seems, or as I do in this patch, modify the behaviour of existing
relocations when applied to e_li instructions.

sim/cris: Fix references to cgen cpu directory
Don't assume that cgen is located within the binutils-gdb tree. We
already have CGEN_CPU_DIR and CPU_DIR defined, these are the cpu/
directory within cgen, and the cpu/ directory within binutils-cpu.
The cris target tries to find CPU_DIR relative to the cgen source
tree, which can be wrong when building with an out of tree cgen.

sim/opcodes: Allow use of out of tree cgen source directory
When configuring with '--enbale-cgen-maint' the default for both the
opcodes/ and sim/ directories is to assume that the cgen source is
within the binutils-gdb source tree as binutils-gdb/cgen/.
In the old cvs days, this worked well, as cgen was just another
sub-module of the single cvs repository and could easily be checked
out within the binutils-gdb directory, and managed by cvs in the
normal way.
Now that binutils-gdb is in git, while cgen is still in cvs, placing
the cgen respository within the binutils-gdb tree is more troublesome,
and it would be nice if the two tools could be kept separate.
Luckily there is already some initial code in the configure.ac files
for both opcodes/ and sim/ to support having cgen be located outside
of the binutils-gdb tree, however, this was speculative code written
imagining a future where cgen would be built and installed to some
location.
Right now there is no install support for cgen, and so the configure
code in opcodes/ and sim/ doesn't really do anything useful. In this
commit I repurpose this code to allow binutils-gdb to be configured so
that it can make use of a cgen source directory that is outside of the
binutils-gdb tree.
With this commit applied it is now possible to configure and build
binutils-gdb like this:
/path/to/binutils-gdb/src/configure --enable-cgen-maint=/path/to/cgen/src/cgen/
make all-opcodes
make -C opcodes run-cgen-all
Just in case anyone is still using cgen inside the binutils-gdb tree,
I have left the default behaviour of '--enable-cgen-maint' (with no
parameter) unchanged, that is it looks for the cgen directory as
'binutils-gdb/cgen/'.

opcodes/riscv: Hide '.L0 ' fake symbols
The RISC-V assembler generates fake labels with the name '.L0 ' as
part of the debug information (see
gas/config/tc-riscv.h:FAKE_LABEL_NAME).
The problem is that currently, when disassembling an object file, the
output looks like this (this is an example from the GDB testsuite, but
is pretty representative of anything with debug information):

The frequent repeated '.L0 ' labels are pointless, as they are
non-unique there's no way to match a use of '.L0 ' to its appearence
in the output, so we'd be better off just not printing it at all.
That's what this patch does by defining a 'symbol_is_valid' method for
RISC-V. With this commit, the same disassembly now looks like this:

In order to share the fake label between the assembler and the
libopcodes library, I've added some new defines RISCV_FAKE_LABEL_NAME
and RISCV_FAKE_LABEL_CHAR in include/opcode/riscv.h. I could have
just moved FAKE_LABEL_NAME to the include file, however, I thnk this
would be confusing, someone working on the assembler would likely not
expect to find FAKE_LABEL_NAME defined outside of the assembler source
tree. By introducing the RISCV_FAKE_LABEL_* defines I can leave the
assembler standard FAKE_LABEL_ defines in the assembler source, but
still share the RISCV_FAKE_LABEL_* with libopcodes.

RISCV_FAKE_LABEL_NAME.

Use separate sed expressions to escape auto-load directories.
Not all sed implementations support alternation via \| in the default
regular expressions. Instead, resort to separate sed expressions via
-e for $debugdir and $datadir. This fixes the default setting of the
auto-load directories on FreeBSD. Previously on FreeBSD the sed
invocation was a no-op causing the debugdir and datadir values to be
expanded yielding an autoload path of ':${prefix}/share/gdb'.
gdb/ChangeLog:
* configure: Re-generate.
* configure.ac: Use separate sed expressions to escape variables
in auto-load directories.

[aarch64] Add support for pointer authentication B key
Armv8.3-A has another key used in pointer authentication called the
B-key (other than the A-key that is already supported). In order for
stack unwinders to work it is necessary to be able to identify frames
that have been signed with the B-key rather than the A-key and it was
felt that keeping this as an augmentation character in the CIE was the
best bet. The DWARF extensions for ARM therefore propose to add a new
augmentation character 'B' to the CIE augmentation string and the
corresponding cfi directive ".cfi_b_key_frame". I've made the relevant
changes to GAS and LD to add support for B-key unwinding, which required
modifying LD to check for 'B' in the augmentation string, adding the
".cfi_b_key_frame" directive to GAS and adding a "pauth_key" field to
GAS's fde_entry and cie_entry structs.
The pointer authentication instructions will behave as NOPs on
architectures that don't support them, and so a check for the
architecture being assembled for is not necessary since there will be no
behavioural difference between augmentation strings with and without the
'B' character on such architectures.

gdb/riscv: Improve logic for when h/w float abi should be used
Currently, if the target announces that it has floating point
registers in its target description then GDB assumes that the hardware
float ABI should be used. However, there's nothing stopping a user
compiling a program for the soft-float abi, and then trying to run
this on a target with hardware floating point registers.
This commit adjusts the logic that decides if GDB should use the
hardware float abi. The primary decision now is based on what the ELF
currently being executed says in its headers. If the file was
compiled for h/w float abi, then GDB uses h/w float abi, otherwise s/w
float is used.
If the current BFD is not an ELF then we don't currently have a
mechanism for figuring out if the file was compiled for float or not.
In this case we disable the h/w float abi. This shouldn't be a
problem as, right now, the RISC-V linker can only produce ELFs.
If there is NO current BFD (can this happen?) then we will enable h/w
float abi if the target has floating point hardware, otherwise, s/w
float abi is used.
This commit also adds some sanity checking that the features requested
in the BFD (xlen and flen) match the target description.
For testing I ran the testsuite on a target that returns a target
description containing both integer and floating point registers, but
used a compiler that didn't have floating point support. Before this
commit I would see failures on may tests that made inferior calls
using floating point arguments, after this commit, all of these issues
are resolved. One example from the testsuite is
gdb.base/infcall-nested-structs.exp.
gdb/ChangeLog:
* riscv-tdep.c (riscv_features_from_gdbarch_info): New function.
(riscv_find_default_target_description): Use new function to
extract feature from gdbarch_info.
(riscv_gdbarch_init): Add error checks for xlen and flen between

think the hardware floating point abi should be used.

gdb/testsuite/sim: Remove redundant setting of timeout
In the config/sim.exp file two functions are defined. Both of these
functions define local timeout variables and then call gdb_expect,
which (through a call to get_largest_timeout) will find the local
definition of timeout.
However, both of these functions set the local timeout to some
arbitrary value and print a log message for this "new" timeout just
before returning.
As in both cases, the timeout is a local variable, this final setting
of the timeout has no effect and can be removed.
As having log messages about the timeout being adjusted could cause
confusion I've removed all logging related to timeouts in this
function, timeouts are adjusted throughout the testsuite without any
logging, there doesn't seem to be any good reason why these functions
should get their own logging.
With the logging gone there seems to be little need to a local timeout
variable at all, and so I've folded the local timeout directly into
the call to gdb_expect.
gdb/testsuite/ChangeLog:
* config/sim.exp (gdb_target_sim): Remove redundant adjustment of
local timeout variable before return, and remove all local timeout
variable entirely.
(gdb_load): Likewise.

AArch64: Racy: Don't set empty set of hardware BPs/WPs on new thread
On some heavily loaded AArch64 boxes, GDB will sometimes hang forever when
the inferior creates a thread. This hang happens inside the kernel during
the ptrace call to set hardware watchpoints or hardware breakpoints.
Currently, GDB will always set hw wp/bp at the start of each thread even if
there are none set in the process.
This patch works around the issue by avoiding setting hw wp/bp if there
are none set for the process.
On an effected machine, this fix drastically reduces the racy nature of the
gdb.threads test set. I ran the entire gdb test suite across all processors
for 100 iterations, then ran the results through the racy tests script.
Without the patch, 58 .exp files in gdb.threads were marked as racy. After
the patch this reduced to the same ~14 tests as the non effected boxes.
Clearly GDB will still be subject to hangs on an effect box if hw wp/bp's are
used prior to creating inferior threads on a heavily loaded system.
To enable this in gdbserver, the sequence in gdbserver add_lwp() is switched
to the same as gdb order as gdb, to ensure the thread is registered before
calling new_thread(). This allows aarch64_linux_new_thread() to read the
ptid.

this property should not be removed from output to indicate it has zero

[aarch64] - Only use MOV for disassembly when shifter op is LSL #0
ARM Architecture Reference Manual for the profile ARMv8-A, Issue C.a,
states that MOV (register) is an alias of the ORR (shifted register)
iff shift == '00' && imm6 == '000000' && Rn == '11111'. However, mov
is currently preferred for a broader range of orr instructions, which
is incorrect.

[gdb/testsuite] Add gdb-caching-proc.exp testcase
When caching a proc using gdb_caching_proc, it will become less likely to
be executed, and consequently it's going to be harder to detect that the
proc is racy. OTOH, in general the proc is easy to rerun. So, add a
test-case to run all uncached gdb_caching_procs a number of times and detect
inconsistent results.
The purpose of caching is to reduce runtime, so rerunning is somewhat
counter-productive in that aspect, but it's better than uncached, because the
number of reruns is constant-bounded, and the increase in runtime is bound to
this test-case, and can be disabled on slow targets.
Tested on x86_64-linux.

PR23938, should not free memory alloced in obstack by free()
This removes ineffectual and wrong code caching section names in
gas/stabs.c. Code like
seg = subseg_new (name, 0);
...
if (seg->name == name)
seg->name = xstrdup (name);
with the idea of being able to unconditionally free "name" later no
longer works. "name" is referenced by the section hash table as well
as in the section->name field. It would be possible to use
"bfd_rename_section (stdoutput, seg, xstrdup (name))", but instead I
opted for a fairly straight-forward approach of adding extra
parameters to two functions to indicate section name strings should be
freed if possible.

linespec_parser_new allocates a std::vector<symtab *> at line 2756, and stores
the pointer to this vector in PARSER_RESULT (parser)->file_symtabs. At 3
different places in linespec.c, another std::vector is assigned to a
linespec->file_symtabs, without first deleting the current value.
The leak is fixed by assigning the vector itself instead of the pointer.
Everything should be moved, so there is no significant data copy
involved.

Update the conditionals in fbsd-nat.h so they are always honored.
Not all of the architecture-specific FreeBSD target files were
including the right headers to enable conditionals in fbsd-nat.h after
the C++ target conversion. As a result, certain operations like 'info
auxv' and 'p $_siginfo' were not working for some native targets
(noticed on RISC-V). Fix this in a couple of ways:
1) Declare fbsd_nat_target::xfer_partial unconditionally and only use
conditionals in the function body for individual target objects.
Originally this function was only used to read the ELF auxiliary
vector, so the entire function was conditional on a macro required
for that object (KERN_AUXV_PROC). However, xfer_partial has since
grown support for additional objects. Making the function
unconditional avoids needing to add the right header to fbsd-nat.h
and allows each target object to use independent requirements.
This did require using a more explicit conditional test for the
$_siginfo support. Removing the "outer" KERN_PROC_AUXV test
enabled $_siginfo for all kernels with PT_LWPINFO, but some older
kernels (FreeBSD 6.0) exposed PT_LWPINFO with a different siginfo
format. Instead use an explicit test for when the current siginfo
format was adopted (shipped in FreeBSD 7.0). This actually enables
$_siginfo on a wider range of kernels as KERN_PROC_AUXV wasn't
introduced until FreeBSD 9.1/10.0.
2) Include <sys/proc.h> in fbsd-nat.h for the definition of
TDP_RFPPWAIT that governs support for fork following.
gdb/ChangeLog:
* fbsd-nat.c [__FreeBSD_version >= 700009] (USE_SIGINFO): Macro

GAS/MIPS: Add `-mfix-r5900' option for the R5900 short loop erratum
`-march=r5900' already enables the R5900 short loop workaround.
However, the R5900 ISA and most other MIPS ISAs are mutually
exclusive since R5900-specific instructions are generated as well.
The `-mfix-r5900' option can be used in combination with e.g.
`-mips2' or `-mips3' to generate generic MIPS binaries that also
work with the R5900 target.
This change has been tested with `make RUNTESTFLAGS=mips.exp

`mipsr5900el-elf' and `mips3-unknown-linux-gnu'.

gdb/riscv: Add read_description method for riscv_linux_nat_target
Adds riscv_linux_nat_target::read_description method to find a
suitable target description for the native linux target we are running
on.
Currently this will supply a suitably sized set of x-registers, and
will probe the kernel to see if the f-registers are readable. If they
are readable then we currently assume that the f-registers are the
same size as the x-registers as I don't know of a good way to probe
the f-register length. This will obviously need fixing in future.
As of Linux 4.19 there is no ptrace support for reading the
f-registers, this should appear in 4.20, so right now we only return
target descriptions without f-registers.

gdb/riscv: Create each unique target description only once
GDB relies on the fact that if two target descriptions have the same
contents, then they will be the same object instance (having the same
address). One place where this is a requirement is in
GDBARCH_LIST_LOOKUP_BY_INFO which is used to find previously created
gdbarch objects.
In GDBARCH_LIST_LOOKUP_BY_INFO a pointer comparison is made on the
gdbarch's target description, if the pointers are different then it is
assumed the gdbarches have different, non-compatible target
descriptions.
Previously we would create duplicate target descriptions in the belief
that RISCV_GDBARCH_INIT would spot this duplication and discard the
second instance. However, this was incorrect, and instead we ended up
creating duplicate gdbarch objects.
With this commit every unique feature set will create one and only one
target description, the feature set and resulting target description
is then cached so that the same target description object can be
returned later.
Many other target avoid this problem by creating a small number of
named target descriptions, and returning one of these. However, we
currently have 8 possible target descriptions (32 vs 64 bit for x-reg
and f-reg, and h/w or s/w float abi) and creating each of these just
to avoid a dynamic cache seems pointless.

Fix dwarf2read.c:dwarf2_find_containing_comp_unit's binary search
First of all, I would like to express my gratitude to Keith Seitz, Jan
Kratochvil and Tom Tromey, who were really kind and helped a lot with
this bug. The patch itself was authored by Jan.
This all began with:
https://bugzilla.redhat.com/show_bug.cgi?id=1639242
py-bt is broken, results in exception
In summary, the error reported by the bug above is:
$ gdb -args python3
GNU gdb (GDB) Fedora 8.1.1-3.fc28
(...)
Reading symbols from python3...Reading symbols from /usr/lib/debug/usr/bin/python3.6-3.6.6-1.fc28.x86_64.debug...done.
done.
Dwarf Error: could not find partial DIE containing offset 0x316 [in module /usr/lib/debug/usr/bin/python3.6-3.6.6-1.fc28.x86_64.debug]
After a long investigation, and after thinking that the problem might
actually be on DWZ's side, we were able to determine that there's
something wrong going on when
dwarf2read.c:dwarf2_find_containing_comp_unit performs a binary search
over all of the CUs belonging to an objfile in order to find the CU
which contains a DIE at an specific offset. The current algorithm is:
static struct dwarf2_per_cu_data *
dwarf2_find_containing_comp_unit (sect_offset sect_off,
unsigned int offset_in_dwz,
struct dwarf2_per_objfile *dwarf2_per_objfile)
{
struct dwarf2_per_cu_data *this_cu;
int low, high;
const sect_offset *cu_off;
low = 0;
high = dwarf2_per_objfile->all_comp_units.size () - 1;
while (high > low)
{
struct dwarf2_per_cu_data *mid_cu;
int mid = low + (high - low) / 2;
mid_cu = dwarf2_per_objfile->all_comp_units[mid];
cu_off = &mid_cu->sect_off;
if (mid_cu->is_dwz > offset_in_dwz
|| (mid_cu->is_dwz == offset_in_dwz && *cu_off >= sect_off))
high = mid;
else
low = mid + 1;
}
For the sake of this example, let's consider that "sect_off =
0x7d".
There are a few important things going on here. First,
"dwarf2_per_objfile->all_comp_units ()" will be sorted first by
whether the CU is a DWZ CU, and then by cu->sect_off. In this
specific bug, "offset_in_dwz" is false, which means that, for the most
part of the loop, we're going to do "high = mid" (i.e, we'll work with
the lower part of the vector).
In our particular case, when we reach the part where "mid_cu->is_dwz
== offset_in_dwz" (i.e, both are false), we end up with "high = 2" and
"mid = 1". I.e., there are only 2 elements in the vector who are not
DWZ. The vector looks like this:
#0: cu->sect_off = 0; length = 114; is_dwz = false <-- low
#1: cu->sect_off = 114; length = 7796; is_dwz = false <-- mid
#2: cu->sect_off = 0; length = 28; is_dwz = true <-- high
...
The CU we want is #1, which is exactly where "mid" is. Also, #1 is
not DWZ, which is also exactly what we want. So we perform the second
comparison:
(mid_cu->is_dwz == offset_in_dwz && *cu_off >= sect_off)
^^^^^^^^^^^^^^^^^^^
Because "*cu_off = 114" and "sect_off = 0x7d", this evaluates to
false, so we end up with "low = mid + 1 = 2", which actually gives us
the wrong CU (i.e., a CU that is DWZ). Next in the code, GDB does:
gdb_assert (low == high);
this_cu = dwarf2_per_objfile->all_comp_units[low];
cu_off = &this_cu->sect_off;
if (this_cu->is_dwz != offset_in_dwz || *cu_off > sect_off)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
{
if (low == 0 || this_cu->is_dwz != offset_in_dwz)
error (_("Dwarf Error: could not find partial DIE containing "
"offset %s [in module %s]"),
sect_offset_str (sect_off),
bfd_get_filename (dwarf2_per_objfile->objfile->obfd));
...
Triggering the error we saw in the original bug report.
It's important to notice that we see the error message because the
selected CU is a DWZ one, but we're looking for a non-DWZ CU here.
However, even when the selected CU is *not* a DWZ (and we don't see
any error message), we still end up with the wrong CU. For example,
suppose that the vector had:
#0: cu->sect_off = 0; length = 114; is_dwz = false
#1: cu->sect_off = 114; length = 7796; is_dwz = false
#2: cu->sect_off = 7910; length = 28; is_dwz = false
...
I.e., #2's "is_dwz" is false instead of true. In this case, we still
want #1, because that's where the DIE is located. After the loop ends
up in #2, we have "is_dwz" as false, which is what we wanted, so we
compare offsets. In this case, "7910 >= 0x7d", so we set "mid = high
= 2". Next iteration, we have "mid = 0 + (2 - 0) / 2 = 1", and thus
we examining #1. "is_dwz" is still false, but "114 >= 0x7d" also
evaluates to false, so "low = mid + 1 = 2", which makes the loop stop.
Therefore, we end up choosing #2 as our CU, even though #1 is the
right one.
The problem here is happening because we're comparing "sect_off"
directly against "*cu_off", while we should actually be comparing
against "*cu_off + mid_cu->length" (i.e., the end offset):
...
|| (mid_cu->is_dwz == offset_in_dwz
&& *cu_off + mid_cu->length >= sect_off))
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
...
And this is what the patch does. The idea is that if GDB is searching
for an offset that falls above the *end* of the CU being
analyzed (i.e., "mid"), then the next iteration should try a
higher-offset CU next. The previous algorithm was using
the *beginning* of the CU.
Unfortunately, I could not devise a testcase for this problem, so I am
proposing a fix with this huge explanation attached to it in the hope
that it is sufficient. After talking a bit to Keith (our testcase
guru), it seems that one would have to create an objfile with both DWZ
and non-DWZ sections, which may prove very hard to do, I think.
I ran this patch on our BuildBot, and no regressions were detected.

target_ops::to_stratum -> target_ops::stratum() virtual method
Given that a target's stratum is a property of the type, and not of an
instance of the type, get rid of to_stratum data field and replace it
with a virtual method.
I.e., when we have e.g., 10 target remote instances active, there's no
need for each of the instances to have their own to_stratum copy.

Convert default_child_has_foo functions to process_stratum_target methods
This patch converts the default_child_has_foo functions to
process_stratum_target methods. This simplifies "regular"
non-inf_child process_stratum targets, since they no longer have to
override the target_ops::has_foo methods to call the default_child_foo
functions. A couple targets need to override the new defaults
(corelow and tracefiles), but it still seems like a good tradeoff,
since those are expected to be little different (target doesn't run).

Avoid buffer overflow in value_x_unop
Commit 6b1747cd1 ("invoke_xmethod & array_view") contains this change:
- argvec = (struct value **) alloca (sizeof (struct value *) * 4);
+ value *argvec_storage[3];
+ gdb::array_view<value *> argvec = argvec_storage;
However, value_x_unop still does:
argvec[2] = value_from_longest (builtin_type (gdbarch)->builtin_int, 0);
argvec[3] = 0;
This triggers an error with -fsanitize=address from userdef.exp:
ERROR: AddressSanitizer: stack-buffer-overflow on address 0x7ffdcf185068 at pc 0x000000e4f912 bp 0x7ffdcf184d80 sp 0x7ffdcf184d70

#0 0xe4f911 in value_x_unop(value*, exp_opcode, noside) ../../binutils-gdb/gdb/valarith.c:557
[...]
I think the two assignments to argvec[3] should just be removed, and
that this was intended in the earlier patch but just missed.
This passes userdef.exp with -fsanitize=address.

Fix use-after-free in gdbserver
-fsanitize=address pointed out a use-after-free in gdbserver. In
particular, handle_detach could reference "process" after it was
deleted by detach_inferior. Avoiding this also necessitated changing

Tested by the buildbot using a few of the gdbserver builders.

Document purpose of each ld statement lists
When discovering the statement lists via their header variable
statement_list, file_chain and input_file_chain it can be confusing to
figure out what they are for. They can point to the same initial
statement and the relation between the next field they use is not
obvious from the name.
This commit adds comment for each of those statement list header to
explain what they are for and what next field they use. It also rewrite
the comment for the next fields to simply redirect the reader to the
list header to avoid duplication of documentation.

[ARM] Update knowledge of bfd architectures
Commit c0c468d562649df0f695737262b6230b7a56a4bb updated bfd's knowledge
of Arm architectures to Armv5TEJ and later but missed the list of CPUs
recognized by objdump -d -m<cpu>.
.note.gnu.arm.ident related code is intentionally not updated as build
attributes are a better mechanism to express the ISA in a file. However
this patch adds tests for the existing code since no existing testcase
cover those codepaths. Since I've only ever managed for
bfd_arm_get_mach_from_notes () to have an effect by using objcopy on
a file with a note but no Arm build attribute, the tests make use of
both objcopy actions supported by run_dump_test which requires to have a
ld line as well.
Note that the CPU list in bfd/cpu-arm.c was simply copied over from
GAS' CPU list but sorted alphabetically as already done for existing
entries.

MIPS/LD: Accept high-part relocations in PIC code with absolute symbols
Accept R_MIPS_HI16, R_MIPS_HIGHER and R_MIPS_HIGHEST relocations and
their compressed counterparts in PIC code where the symbol referred is
absolute. Such an operation is meaningful, because an absolute symbol
effectively is a constant the calculation of the value of which has been
deferred to the static link time, and which is not going to change any
further at the dynamic load time. Therefore there is no need ever to
refuse the use of these relocations with such symbols, as the resulting
run-time value observed by the program will be correct even in PIC code.
This is not the case with R_MIPS_26 and its compressed counterparts,
because the run-time value calculated by the instructions these
relocations are used with depends on the address of the instruction
itself, and that can change according to the base address used by the
dynamic loader. Therefore these relocations have to continue being
rejected in PIC code even with absolute symbols.
This allows successful linking of code that relies on previous linker
behavior up to commit 861fb55ab50a ("Defer allocation of R_MIPS_REL32
GOT slots"), <https://sourceware.org/ml/binutils/2008-08/msg00096.html>,
which introduced the problematic check missing this special exception

MIPS/LD: Continue processing with refused relocations in PIC code
Switch from `_bfd_error_handler' to `info->callbacks->einfo' with error
reporting concerning the use of position-dependent relocations such as
R_MIPS_HI16 or R_MIPS_26 in PIC code and continue processing so that any
subsequent link errors are also shown rather than the linker terminating
right away. This can reduce user frustration where correcting one error
only reveals another one; instead all are shown together making them all
possible to investigate at once. The use of the `%X' specifier causes
the linker to terminate unsuccessfully at the end of processing.
Also fix the message to say `cannot' rather than `can not'.

LD: Convert `%P: %H:' to `%H:' in error messages
Similarly to commit 174d0a74a2e6 ("PowerPC/BFD: Convert `%P: %H:' to
`%H:' in error messages") convert linker relocation error messages to
use `%H:' rather `%P: %H:', removing inconsistent message composition
like:
$ cat reloc-j.s
.text
.globl foo
.ent foo
foo:
j bar
j bar
.end foo
$ cat reloc-j.ld
SECTIONS
{
bar = 0x12345678;
.text : { *(.text) }
/DISCARD/ : { *(*) }
}
$ as -o reloc-j.o reloc-j.s
$ ld -T reloc-j.ld -o reloc-j reloc-j.o
ld: tmpdir/reloc-j.o: in function `foo':
(.text+0x0): relocation truncated to fit: R_MIPS_26 against `bar'
ld: (.text+0x8): relocation truncated to fit: R_MIPS_26 against `bar'
$
where subsequent lines referring to issues within a single function have
the name of the linker executable prepended, but the first one does not.
As noted with the commit referred this breaks a GNU Coding Standard's
requirement that error messages from compilers should look like this:
source-file-name:lineno: message
also quoted in `vfinfo' code handling these specifiers.
Remove the linker name prefix then, making the messages now look like:
$ ld -T reloc-j.ld -o reloc-j reloc-j.o
tmpdir/reloc-j.o: in function `foo':
(.text+0x0): relocation truncated to fit: R_MIPS_26 against `bar'

AArch64: Fix regression in Cortex A53 erratum when PIE. (PR ld/23904)
The fix for PR ld/22263 causes TLS relocations using ADRP to be relaxed
into MOVZ, however this causes issues for the erratum code.
The erratum code scans the input sections looking for ADRP instructions
and notes their location in the stream.
It then later tries to find them again in order to generate the linker
stubs. Due to the relaxation it instead finds a MOVZ and hard aborts.
Since this relaxation is a valid one, and in which case the erratum no
longer applies, it shouldn't abort but instead just continue.
This changes the TLS relaxation code such that when it finds an ADRP and
it relaxes it, it removes the erratum entry from the work list by changing
the stub type into none so the stub is ignored.
The entry is not actually removed as removal is a more expensive operation
and we have already allocated the memory anyway.
The clearing is done for IE->LE and GD->LE relaxations, and a testcase is
added for the IE case. The GD case I believe to be impossible to get together
with the erratum sequence due to the required BL which would break the sequence.
However to cover all basis I have added the guard there as well.

Implement timestamp'ed output on "make check"
It is unfortunately not uncommon to have tests hanging on some of the
BuildBot workers. For example, the ppc64be/ppc64le+gdbserver builders
are especially in a bad state when it comes to testing GDB/gdbserver,
and we can have builds that take an absurd amount of time to
finish (almost 1 week for one single build, for example).
It may be hard to diagnose these failures, because sometimes we don't
have access to the faulty systems, and other times we're just too busy
to wait and check which test is actually hanging. During one of our
conversations about the topic, someone proposed that it would be a
good idea to have a timestamp put together with stdout output, so that
we can come back later and examine which tests are taking too long to
complete.
Here's my proposal to do this. The very first thing I tried to do was
to use "ts(1)" to achieve this feature, and it obviously worked, but
the problem is that I'm afraid "ts(1)" may not be widely available on
every system we support. Therefore, I decided to implement a *very*
simple version of "ts(1)", in Python 3, which basically does the same
thing: iterate over the stdin lines, and prepend a timestamp onto
them.
As for testsuite/Makefile.in, the user can now specify two new
variables to enable timestamp'ed output: TS (which enables the
output), and TS_FORMAT (optional, used to specify another timestamp
format according to "strftime").
Here's an example of how the output looks like:
...

...
(What, gdb.base/quit-live.exp is taking 26 seconds to complete?!)
Output to stderr is not timestamp'ed, but I don't think that will be a
problem for us. If it is, we can revisit the solution and extend it.

gdbserver: AArch64: Remove cannot_fetch/store_register
The cannot store/fetch register functions are only used for checking
if a register can be accessed using PEEKUSER/POKEUSER.
The AArch64 port doesn't support this method of access, so remove the
unused functions.

Per-inferior thread list, thread ranges/iterators, down with ALL_THREADS, etc.
As preparation for multi-target, this patch makes each inferior have
its own thread list.
This isn't absolutely necessary for multi-target, but simplifies
things. It originally stemmed from the desire to eliminate the
init_thread_list calls sprinkled around, plus it makes it more
efficient to iterate over threads of a given inferior (no need to
always iterate over threads of all inferiors).
We still need to iterate over threads of all inferiors in a number of
places, which means we'd need adjust the ALL_THREADS /
ALL_NON_EXITED_THREADS macros. However, naively tweaking those macros
to have an extra for loop, like:
#define ALL_THREADS (thr, inf) \
for (inf = inferior_list; inf; inf = inf->next) \
for (thr = inf->thread_list; thr; thr = thr->next)
causes problems with code that does "break" or "continue" within the
ALL_THREADS loop body. Plus, we need to declare the extra "inf" local
variable in order to pass it as temporary variable to ALL_THREADS
(etc.)
It gets even trickier when we consider extending the macros to filter
out threads matching a ptid_t and a target. The macros become tricker
to read/write. Been there.
An alternative (which was my next attempt), is to replace the
ALL_THREADS etc. iteration style with for_each_all_threads,
for_each_non_exited_threads, etc. functions which would take a
callback as parameter, which would usually be passed a lambda.
However, I did not find that satisfactory at all, because the
resulting code ends up a little less natural / more noisy to read,
write and debug/step-through (due to use of lambdas), and in many
places where we use "continue;" to skip to the next thread now need to
use "return;". (I ran into hard to debug bugs caused by a
continue/return confusion.)
I.e., before:
ALL_NON_EXITED_THREADS (tp)
{
if (tp->not_what_I_want)
continue;
// do something
}
would turn into:
for_each_non_exited_thread ([&] (thread_info *tp)
{
if (tp->not_what_I_want)
return;
// do something
});
Lastly, the solution I settled with was to replace the ALL_THREADS /
ALL_NON_EXITED_THREADS / ALL_INFERIORS macros with (C++20-like) ranges
and iterators, such that you can instead naturaly iterate over
threads/inferiors using range-for, like e.g,.:
// all threads, including THREAD_EXITED threads.
for (thread_info *tp : all_threads ())
{ .... }
// all non-exited threads.
for (thread_info *tp : all_non_exited_threads ())
{ .... }
// all non-exited threads of INF inferior.
for (thread_info *tp : inf->non_exited_threads ())
{ .... }
The all_non_exited_threads() function takes an optional filter ptid_t as
parameter, which is quite convenient when we need to iterate over
threads matching that filter. See e.g., how the
set_executing/set_stop_requested/finish_thread_state etc. functions in
thread.c end up being simplified.
Most of the patch thus is about adding the infrustructure for allowing
the above. Later on when we get to actual multi-target, these
functions/ranges/iterators will gain a "target_ops *" parameter so
that e.g., we can iterate over all threads of a given target that
match a given filter ptid_t.
The only entry points users needs to be aware of are the
all_threads/all_non_exited_threads etc. functions seen above. Thus,
those functions are declared in gdbthread.h/inferior.h. The actual
iterators/ranges are mainly "internals" and thus are put out of view
in the new thread-iter.h/thread-iter.c/inferior-iter.h files. That
keeps the gdbthread.h/inferior.h headers quite a bit more readable.
A common/safe-iterator.h header is added which adds a template that
can be used to build "safe" iterators, which are forward iterators
that can be used to replace the ALL_THREADS_SAFE macro and other
instances of the same idiom in future.
There's a little bit of shuffling of code between
gdbthread.h/thread.c/inferior.h in the patch. That is necessary in
order to avoid circular dependencies between the
gdbthread.h/inferior.h headers.
As for the init_thread_list calls sprinkled around, they're all
eliminated by this patch, and a new, central call is added to
inferior_appeared. Note how also related to that, there's a call to
init_wait_for_inferior in remote.c that is eliminated.
init_wait_for_inferior is currently responsible for discarding skipped
inline frames, which had to be moved elsewhere. Given that nowadays
we always have a thread even for single-threaded processes, the
natural place is to delete a frame's inline frame info when we delete
the thread. I.e., from clear_thread_inferior_resources.

Fix follow_exec latent problem
A following commit to make each inferior have its own thread list
exposes a problem with bf93d7ba99 ("Add thread after updating gdbarch
when exec'ing"), which is that we can't defer adding the thread
because that breaks try_open_exec_file which deep inside ends up
calling inferior_thread():

The problem is latent currently because inferior_thread() at that
point manages to return a thread, even though it's the wrong one (of
the old inferior).
The problem originally fixed by bf93d7ba99 was:
(...) we should avoid doing register reads
after a process does an exec and before we've updated that inferior's
gdbarch. Otherwise, we may interpret the registers using the wrong
architecture.
(...) The call to "add_thread" done just after adding the inferior is
problematic, because it ends up reading the registers (because the ptid
is re-used, we end up doing a switch_to_thread to it, which tries to
update stop_pc). (...)
The register-reading issue is no longer a problem nowadays, ever since
switch_to_thread stopped reading the stop_pc in git commit
f2ffa92bbce9 ("gdb: Eliminate the 'stop_pc' global").
So this commit basically reverts bf93d7ba99.

Avoid find_thread_ptid with null_ptid
With a following patch, find_thread_ptid will first find the inferior
for the passed-in ptid, using find_inferior_pid, and then look for the
thread in that inferior's thread list. If we pass down null_ptid to
find_thread_ptid then that means we'll end up passing 0 to
find_inferior_pid, which hits this assertion:
> struct inferior *
> find_inferior_pid (int pid)
> {
> struct inferior *inf;
>
> /* Looking for inferior pid == 0 is always wrong, and indicative of
> a bug somewhere else. There may be more than one with pid == 0,
> for instance. */
> gdb_assert (pid != 0);
This patch prepares for the change, by avoiding passing down null_ptid
to find_thread_ptid or to functions that naturally use it, such as the
target_pid_to_str call in inferior.c:add_inferior. In that latter
case, the patch changes GDB output,
from:
(gdb) add-inferior
[New inferior 2 (process 0)]
to:
(gdb) add-inferior
[New inferior 2]
which seems like a good change to me. It might not even make sense to
talk about "process" for the current target, for example.
The python_on_normal_stop change ends up avoiding looking up the
same thread twice (inferior_thread also does a look up).

Make command-repeat work after gdb.execute
Since commit
56bcdbea2bed ("Let gdb.execute handle multi-line commands")
command repetition after using the `gdb.execute` Python function
fails (the previous command is not repeated anymore). This happens
because read_command_lines_1 sets dont_repeat, but the call to
prevent_dont_repeat in execute_gdb_command is later.
The fix is to move the call to prevent_dont_repeat to the beginning of
the function.
Tested on my laptop (ArchLinux-x86_64).

Fix linking MSP430 files created by gcc's LTO optimizer.
When invoking GCC with "-g -flto", the compiler will create LTO objects
with debug information. The objects created are "simple ELF" objects (see
libiberty/simple-object-elf.c) and do not have target-specific sections.
When the MSP430 linker sees one of these objects without a .MSP430.attributes
section it errors:
> error: /tmp/cc4LhbEI.ltrans0.ltrans.o uses MSP430X instructions but /tmp/ccynqIwudebugobj uses unknown
> error: /tmp/cc4LhbEI.ltrans0.ltrans.o uses the small code model whereas /tmp/ccynqIwudebugobj uses the unknown code model
> error: /tmp/cc4LhbEI.ltrans0.ltrans.o uses the small data model whereas /tmp/ccynqIwudebugobj uses the unknown data model
> error: /tmp/cc4LhbEI.ltrans0.ltrans.o uses the small code model but /tmp/ccynqIwudebugobj uses the unknown data model
> failed to merge target specific data of file /tmp/cc4LhbEI.ltrans0.ltrans.o
The following patch allows these debug LTO objects to be linked with other
MSP430 objects even if they do not have a .MSP430.attributes section.
bfd * elf32-msp430.c (elf32_msp430_merge_mspabi_attributes): Do not
error when .MSP430.attributes section is missing from objects
created by LTO.

gdb/riscv: Add target description support
This commit adds target description support for riscv.
I've used the split feature approach for specifying the architectural
features, and the CSR feature is auto-generated from the riscv-opc.h
header file.
If the target doesn't provide a suitable target description then GDB
will build one by looking at the bfd headers.
This commit does not implement target description creation for the
Linux or FreeBSD native targets, both of these will need to add
read_description methods into their respective target classes, which
probe the target features, and then call
riscv_create_target_description to build a suitable target
description. Until this is done Linux and FreeBSD will get the same
default target description based on the bfd that bare-metal targets
get.
I've only added feature descriptions for 32 and 64 bit registers, 128
bit registers (for RISC-V) are not supported in the reset of GDB yet.
This commit removes the special reading of the MISA register in order
to establish the target features, this was only used for figuring out
the f-register size, and even that wasn't done consistently. We now
rely on the target to tell us what size of registers it has (or look
in the BFD as a last resort). The result of this is that we should
now support RV64 targets with 32-bit float, though I have not
extensively tested this combination yet.

valops.c: Overload resolution code: Rename parameters/locals
While looking over this code, I thought the names of the parameters to
find_oload_champ and related functions and locals were a bit too
cryptic. For example, FN_LIST holds methods, not free functions.
Free-functions are in OLOAD_SYMS.
This patch renames parameters/variables to the more obvious
methods/xmethods/functions instead.

valops.c: Some more gdb::array_view
This commit replaces some more use of pointer+length pairs in the
overload resolution code with gdb::array_view.
find_oload_champ's interface is simplified/normalized: the xmethods
parameter is converted from std::vector to array pointer, and then the
num_fns parameter is always passed in, no matter the array which is
non-NULL. I tweaked the formatting of callers a little bit here and
there so that the 3 optional parameters are all in the same line. (I
tried making the 3 optional array parameters be array_views, but the
resulting code didn't look as nice.)

C++ify badness_vector, fix leaks
badness_vector is currently an open coded vector. This reimplements
it as a std::vector.
This fixes a few leaks as well:
- find_oload_champ is leaking every badness vector calculated bar the
one returned.
- bv->rank is always leaked, since callers of rank_function only
xfree the badness_vector pointer, not bv->rank.

invoke_xmethod & array_view
This replaces more pointer+length with gdb::array_view. This time,
around invoke_xmethod, and then propagating the fallout around, which
inevitably leaks to the overload resolution code.
There are several places in the code that want to grab a slice of an
array, by advancing the array pointer, and decreasing the length
pointer. This patch introduces a pair of new
gdb::array_view::slice(...) methods to make that convenient and clear.
Unit test included.

Use gdb:array_view in call_function_by_hand & friends
This replaces a few uses of pointer+length with gdb::array_view, in
call_function_by_hand and related code.
Unfortunately, due to -Wnarrowing, there are places where we can't
brace-initialize an gdb::array_view without an ugly-ish cast. To
avoid the cast, this patch introduces a gdb::make_array_view function.
Unit tests included.
This patch in isolation may not look so interesting, due to
gdb::make_array_view uses, but I think it's still worth it. Some of
the gdb::make_array_view calls disappear down the series, and others
could be eliminated with more (non-trivial) gdb::array_view
detangling/conversion (e.g. code around eval_call). See this as a "we
have to start somewhere" patch.

gdb: Use string_printf to format int fields instead of a fixed size buffer
This patch removes a FIXME comment from cli-out.c, now instead of
formatting integers into a fixed size buffer we build a std::string
and extract the formatted integer from that.
The old code using a fixed size buffer was probably fine (the integer
was not going to overflow it) and probably slightly more efficient
(avoids building a std::string) however, given we already have utility
code in GDB that will allow the 'FIXME' comment to be removed, it
seems like an easy improvement.
gdb/ChangeLog:
* cli-out.c (cli_ui_out::do_field_int): Use string_printf rather
than a fixed size buffer.

gdb: Respect field width and alignment for 'fmt' fields in CLI output
Currently the method 'cli_ui_out::do_field_fmt' has this comment:
/* This is the only field function that does not align. */
The reality is even slightly worse, the 'fmt' field type doesn't
respect either the field alignment or the field width. In at least
one place in GDB we attempt to work around this lack of respect for
field width by adding additional padding manually. But, as is often
the case, this is leading to knock on problems.
Conside the output for 'info breakpoints' when a breakpoint has
multiple locations. This example is taken from the testsuite, from
test gdb.opt/inline-break.exp:
(gdb) info breakpoints
Num Type Disp Enb Address What
1 breakpoint keep y <MULTIPLE>
1.1 y 0x00000000004004ae in func4b at /src/gdb/testsuite/gdb.opt/inline-break.c:64
1.2 y 0x0000000000400682 in func4b at /src/gdb/testsuite/gdb.opt/inline-break.c:64
The miss-alignment of the fields shown here is exactly as GDB
currently produces.
With this patch 'fmt' style fields are now first written into a
temporary buffer, and then written out as a 'string' field. The
result is that the field width, and alignment should now be respected.
With this patch in place the output from GDB now looks like this:
(gdb) info breakpoints
Num Type Disp Enb Address What
1 breakpoint keep y <MULTIPLE>
1.1 y 0x00000000004004ae in func4b at /src/gdb/testsuite/gdb.opt/inline-break.c:64
1.2 y 0x0000000000400682 in func4b at /src/gdb/testsuite/gdb.opt/inline-break.c:64
This patch has been tested on x86-64/Linux with no regressions,
however, the testsuite doesn't always spot broken output formatting or
alignment. I have also audited all uses of 'fmt' fields that I could
find, and I don't think there are any other places that specifically
try to work around the lack of width/alignment, however, I could have
missed something.

* breakpoint.c (print_one_breakpoint_location): Reduce whitespace,
and remove insertion of extra spaces in GDB's output.
* cli-out.c (cli_ui_out::do_field_fmt): Update header comment.
Layout field into a temporary buffer, and then output it as a
string field.
gdb/testsuite/ChangeLog:
* gdb.opt/inline-break.exp: Add test that info breakpoint output
is correctly aligned.

Fix regression 'info variables' does not show minimal symbols.
12615cba8411c8 Add [-q] [-t TYPEREGEXP] [NAMEREGEXP] args to info [args|functions|locals|variables]
introduced a regression that minimal symbols were not listed anymore, due to a wrong
condition checking the absence of a type regexp in the loop scanning the minimal symbols.
Instead, before entering the loop scanning the minimal symbols, check that we
do not have a type regexp, as we will never match a minimal symbol with
this type regexp.
With the fix in this patch, for this part of the code, we basically go back
to the GDB 8.2 logic, with just the addition of
&& !treg.has_value ())
to 'enter' in the minsym case.
This should ensure that at least there is no regression compared to 8.2,
when not using the new type matching argument, as there was no treg in 8.2.

Handle TYPE_CODE_PTR when printing Rust types
This changes the Rust type printers to handle TYPE_CODE_PTR. The
current approach is not ideal, because currently the code can't
distinguish between mut and const, or between pointers and references.
(These are debuginfo deficiencies, for which there are rustc bugs on
file.)
Meanwhile, this at least clears up the case seen in PR rust/23625.

Aarch64: Fix segfault when casting dummy calls
The following will segfault on aarch64 if foo is in another object,
was compiled as c++ and has no debug symbols:
(gdb) p (int)foo()
This is because aarch64_push_dummy_call determines the return type
of the function and then does not check for null pointer.
A null pointer for the return type means the call has no debug
information. For the code to get here, then the call must have
been cast, otherwise we'd error out sooner. In the case of a
no-debug-info call cast, the return type is the type the user
had cast the call to, but we do not have that information
available here.
However, aarch64_push_dummy_call only requires the return type in
order to calculate lang_struct_return. This information is available
in the return_method enum. The fix is to simply use this instead.
Adds testcase to check calls across objects, with all combinations
of c, c++, debug and no debug.

opcodes/nfp: Fix disassembly of crc[] with swapped operands.
The decoding of the CRC operation in alu instructions was using bits
from the instruction word directly, instead of srcA which would be
different if the swap bit was set.

Add completer for skip numbers
Add completer to various commands that accept skip numbers:
- skip enable
- skip disable
- skip delete
- info skip
These commands also accept ranges, the completer works for that but is
not very smart. It will suggest invalid ranges, for example when doing
"2-<TAB>" it will suggest "1", which would not result in a valid range.
Also, it will keep suggesting when doing "1-2-<TAB>", even though it's
an invalid syntax.
A future idea would be to make a re-usable and well-tested completer for
numbers and ranges. I think it could at least be re-used for breakpoint
and thread numbers (for example with the "enable breakpoints" command).
gdb/ChangeLog:
* skip.c (complete_skip_number): New function.
(_initialize_step_skip): Add completers to some skip commands.
gdb/testsuite/ChangeLog:
* gdb.base/skip.exp: Add standard_testfile. Add "skip delete"
completer tests.

[BINUTILS, AARCH64, 6/8] Add Tag getting instruction in Memory Tagging Extension
This patch is part of the patch series to add support for ARMv8.5-A
Memory Tagging Extensions which is an optional extension to

This patch add support to the Bulk Allocation Tag instructions from
MTE. These are the following instructions added in this patch:
- LDGV <Xt>, [<Xn|SP>]!
- STGV <Xt>, [<Xn|SP>]!
This needed a new kind of operand for the new addressing [<Xn|SP>]!
since this has no offset and only takes a pre-indexed version.
Hence AARCH64_OPND_ADDR_SIMPLE_2 and ldtdgv_indexed are introduced.
(AARCH64_OPND_ADDR_SIMPLE fulfilled the no offset criteria but does
not allow writeback). We also needed new encoding and decoding
functions to be able to do the same.

Remove a VEC from remote.c
This removes the VEC from remote_g_packet_data, replacing it with a

destroyed, so this seemed ok.

[gdb/symtab] Fix language of duplicate static minimal symbol
Consider a test-case with source files msym.c:
...
static int foo (void) { return 1; }
...
and msym_main.c:
...
static int foo (void) { return 2; }
int main (void) { return 0; }
..
compiled as c++ with minimal symbols:
...
$ g++ msym_main.c msym.c
...
With objdump -x we find the two foo symbols prefixed with their corresponding
files in the symbol table:
...
0000000000000000 l df *ABS* 0000000000000000 msym_main.c
00000000004004c7 l F .text 000000000000000b _ZL3foov
0000000000000000 l df *ABS* 0000000000000000 msym.c
00000000004004dd l F .text 000000000000000b _ZL3foov
...
However, when we use gdb to print info on foo, both foos are listed, but we
get one symbol mangled and one symbol demangled:
...
$ gdb ./a.out -batch -ex "info func foo"
All functions matching regular expression "foo":
Non-debugging symbols:
0x00000000004004c7 foo()
0x00000000004004dd _ZL3foov
...
During minimal symbol reading symbol_set_names is called for each symbol.
First, it's called with foo from msym.c, an entry is created in
per_bfd->demangled_names_hash and symbol_find_demangled_name is called, which
has the side effect of setting the language of the symbol to language_cplus.
Then, it's called with foo from msym_main.c. Since
per_bfd->demangled_names_hash already has an entry for that name,
symbol_find_demangled_name is not called, and the language of the symbol
remains language_auto.
Fix this by doing the symbol_find_demangled_name call unconditionally.

PowerPC, don't use bfd reloc howto in md_assemble
We support source like the following
.data
.quad x-.
.space 8
x:
where at the time the .quad line is assembled, x is unknown so a fixup
is emitted for later evaluation. This is supported for data even when
the target may not have relocations for the expression, for example,
32-bit powerpc targets lack a 64-bit reloc. As long as the fixup
resolves at assembly time, gas is happy.
The idea of this patch is to support fixups that resolve at assembly
time for instructions too, even when the target might lack the
necessary relocations (and thus no howto).
* config/tc-ppc.c (fixup_size): New function.
(md_assemble): Use it to derive size and pcrel directly
from fixup reloc type.

Avoid crash when calling warning too early
I noticed that if you pass the name of an existing file (not a
directory) as the argument to --data-directory, gdb will crash:
$ ./gdb -nx --data-directory ./gdb
../../binutils-gdb/gdb/target.c:590:56: runtime error: member call on null pointer of type 'struct target_ops'
This was later reported as PR gdb/23838.
This happens because warning ends up calling
target_supports_terminal_ours, which calls current_top_target, which
returns nullptr this early.
This fixes the problem by handling this case specially in
target_supports_terminal_ours. I also changed
target_supports_terminal_ours to return bool.

type Small_Float_Vector is array (1 .. 2) of Float;
function Create_Small_Float_Vector return Small_Float_Vector is

end Create_Small_Float_Vector;
... which declares a type which is an array with 2 floats in it
(floats are 4 bytes on AArch64), trying to get GDB to print
the return value from that function does not work:

Value returned is $1 = (4.25, 4.25)
Because the return type is an HFA, it is returned via the first two
SIMD registers. However, what happens is that the current implementation
fails to realize that this is an HFA, and therefore fetches the return
value from the wrong location. And the reason why it fails to realize
this is because it thinks that our array has 8 elements (HFAs have
a maximum of 4). Looking at aapcs_is_vfp_call_or_return_candidate_1,
where this is determined, we can easily see why (looks like a thinko):
| case TYPE_CODE_ARRAY:
| [...]
| struct type *target_type = TYPE_TARGET_TYPE (type);
| int count = aapcs_is_vfp_call_or_return_candidate_1
| (target_type, fundamental_type);
|
| if (count == -1)
| return count;
|
!! -> | count *= TYPE_LENGTH (type);
| return count;
Here, we first determine the count for one element of our array,
and so we should then be multiplying that count by the number
of elements in our array (2 in our case). But instead, we multiply it
by the total size (8). As a result, we do not classify the return
type as an HFA, and thus pick the wrong location for fetching
the return value.
gdb/ChangeLog:
* aarch64-tdep.c (aapcs_is_vfp_call_or_return_candidate_1):
return the correct count for potential HFAs.
Tested on aarch64-linux, fixes:

x86-64: fix ZMM register state tracking
The three AVX512 state components are entirely independent - one being
in its "init state" has no implication whatsoever on either of the other
two. Fully separate X86_XSTATE_ZMM_H and X86_XSTATE_ZMM handling, to
prevent upper halves of the upper 16 ZMM registers to display as if they
were zero (when they aren't) after e.g. VZEROALL/VZEROUPPER.

gdb/riscv: Handle errors while setting the frame id
When we connect to a remote target one of the first things GDB does is
establish a frame id. If an error is thrown while building this frame
id then GDB will disconnect from the target.
This can mean that, if the user is attempting to connect to a target
that doesn't yet have a program loaded, or the program the user is
going to load onto the target doesn't match what is already loaded, or
the target is just in some undefined state, then the very first
request for a frame id can fail (for example, by trying to load from
an invalid memory address), and GDB will disconnect. It is then
impossible for the user to connect to the target and load a new
program at all.
An example of such a session might look like this:
Reading symbols from ./gdb/testsuite/outputs/gdb.arch/riscv-reg-aliases/riscv-reg-aliases...
(gdb) target remote :37191
Remote debugging using :37191
0x0000000000000100 in ?? ()
Cannot access memory at address 0x0
(gdb) load
You can't do that when your target is `exec'
(gdb) info frame
/path/to/gdb/gdb/thread.c:93: internal-error: thread_info* inferior_thread(): Assertion `tp' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
The solution is to handle errors in riscv_frame_this_id, and leave the
this_id variable with its default value, which is the predefined
'outermost' frame.
With this fix in place, connecting to the same target now looks like
this:
(gdb) target remote :37191

0x0000000000000100 in ?? ()

Make gold testsuite work with CC and CXX specifying -B
The patch allows the gold testsuite to pass when using something like
the following configure line, which works for the rest of the binutils
testsuite. At least, it does if you don't configure your gcc with any
of the options that force a particular path to as or ld.
gccdir="/home/alan/build/gcc/prev-"
gccsrc="/home/alan/src/gcc.git"
gcctarg="x86_64-linux"
CC="${gccdir}gcc/xgcc -B${gccdir}gcc/" \
CXX="${gccdir}gcc/xg++ -B${gccdir}gcc/ -I${gccdir}$gcctarg/libstdc++-v3/include -I${gccdir}$gcctarg/libstdc++-v3/include/$gcctarg -I${gccsrc}/libstdc++-v3/libsupc++ -L${gccdir}$gcctarg/libstdc++-v3/src/.libs/" \
~/src/binutils-gdb/configure ...
gold's -Bgcctestdir/ option must come before the -B supplied by $CC
or $CXX, in order to pick up the linker we want to test. Also when
using a not-yet-installed gcc, it is necessary to provide a collect-ld
in gcctestdir/ as otherwise a collect-ld script in -B${gccdir}gcc/
will be used and the wrong linker tested.
Besides this, the patch fixes some bugs: The $COMPILE -D_FORTIFY_SOURCE
edit was wrong (but worked for usual values), and the $CXXLINK_S edit
unnecessarily but harmlessly used extra backslash quoting. See
posix shell documentation regarding quoting, or
www.gnu.org/software/bash/manual/bashref.html#Command-Substitution
Also, -Bgcctestdir/ in one place makes it less likely a new test will
be added that accidentally lacks the option.

(Ada/tasking) fix array or string index out of range warning
A recent change in the compiler highlighted a small weakness in
the function reading the contents of the Ada Task Control Block
(ATCB -- the data that allows us to inspect Ada tasks). As a result,
anytime we read it, we started getting some warnings. For instance,
using the gdb.ada/tasks.exp testcase...
$ gnatmake -g foo.adb
$ gdb foo
(gdb) b foo.adb:60
Breakpoint 1 at 0x403e07: file foo.adb, line 60.
(gdb) run
[...]
Thread 1 "foo" hit Breakpoint 1, foo () at foo.adb:60
60 for J in Task_List'Range loop -- STOP_HERE
... we can see that the "info tasks" command produces some warnings,
followed by the correct output.
(gdb) info tasks
!! -> warning: array or string index out of range
!! -> warning: array or string index out of range
!! -> warning: array or string index out of range
!! -> warning: array or string index out of range
ID TID P-ID Pri State Name
* 1 654050 48 Runnable main_task
2 654ef0 1 48 Accept or Select Term task_list(1)
3 658680 1 48 Accept or Select Term task_list(2)
4 65be10 1 48 Accept or Select Term task_list(3)
The problem comes from the fact that read_atcb, the function responsible
for loading the contents of the ATCB, blindly tries to read some data
which is only relevant when a task is waiting for another task on
an entry call. A comment in that code's section gives a hint as to
how the information is meant to be decoded:
/* Let My_ATCB be the Ada task control block of a task calling the
entry of another task; then the Task_Id of the called task is
in My_ATCB.Entry_Calls (My_ATCB.ATC_Nesting_Level).Called_Task. */
What the comment shows is that, to get the Id of the task being called,
one has to go through the entry calls field, which is an array pointer.
Up to now, we were lucky that, for tasks that are _not_ waiting on an
entry call, its ATCB atc_nesting_level used to be set to 1, and so
we were able to silently read some irrelevant data. But a recent change
now causes this field to be zero instead, and this triggers the warning,
since we are now trying to read outside of the array's range (arrays
in Ada often start at index 1, as is the case here).
We avoid this issue by simply only reading that data when the data
is actually known to be relevant (state == Entry_Caller_Sleep).
This, in turn, allows us to simplify a bit the use of the task_info->state
field, where we no longer need to check task the task has a state equal
to Entry_Caller_Sleep before using this field. Indeed, with this new
approach, we now know that, unless task_info->state == Entry_Caller_Sleep,
the state is now guaranteed to be zero. In other words, we no longer set
task_info->called_task to some random value, forcing to check the task's
state first as a way to verify that the data is not random.
gdb/ChangeLog:
* ada-lang.c (read_atcb): Only set task_info->called_task if
task_info->state == Entry_Caller_Sleep.
(print_ada_task_info): Do not check task_info->state before
checking task_info->called_task.
(info_task): Likewise.

ada-tasks.c::read_atcb: start from a cleared ada_task_info result
The purpose of this patch is not to fix a bug per se, but rather
to robustify this function to make sure it never returns a struct
ada_task_info where some of the fields are left uninitialized.
Reading the current implementation, it attempts to methodically
set them all one by one: but it's not excluded that a future
change might miss something. A memset is cheap and make sure that
this function returns repeatable results.
This in turns allows us to remove some assignments which have become
redundant.
gdb/ChangeLog:
* ada-tasks.c (read_atcb): Clear task_info before computing
the value of each of its fields.

gdb: Guard against NULL dereference in dwarf2_init_integer_type
In this commit:
commit eb77c9df9f6d2f7aa644a170280fe31ce080f887
Date: Thu Oct 18 14:04:27 2018 +0100
gdb: Handle ICC's unexpected void return type
A potential dereference of a NULL pointer was introduced if a
DW_TAG_base_type is missing a DW_AT_name attribute.
I have taken this opportunity to fix a slight confusion that existed
in the test also added in the above commit, the test had two C
variables, declared like this:
int var_a = 5;
void *var_ptr = &var_a;
However, the fake DWARF in the test script declared them like this:
void var_a = 5;
void *var_ptr = &var_a;
This wasn't a problem as the test never uses 'var_a' directly, this
only exists so 'var_ptr' can be initialised. However, it seemed worth
fixing.
I've also added a test for a DW_TAG_base_type with a missing
DW_AT_name, as clearly there's not test currently that covers this
(the original patch tested cleanly). I can confirm that the new test
causes GDB to crash before this patch, and passes with this patch.
gdb/ChangeLog:
* dwarf2read.c (dwarf2_init_integer_type): Check for name being
NULL before dereferencing it.
gdb/testsuite/ChangeLog:
* gdb.dwarf2/void-type.exp: Rename types, and make var_a an 'int'.
* gdb.dwarf2/missing-type-name.exp: New file.
