MIPS16/GAS: Fix delay slot filling across frags
Fix an assertion failure like:
test.s: Assembler messages:
test.s:3: Internal error!
Assertion failure in append_insn at .../gas/config/tc-mips.c:7523.
Please report this bug.
triggered by assembling MIPS16 code like:
hello:
addiu $4, $4, 4
jr $31
with the generation of a listing file enabled, e.g.:
$ as -mips16 -O2 -aln=test.lst
The cause of the problem is the lack of support for moving instructions
across frags in MIPS16 jump swapping, which triggers more easily with
listing enabled as in that case every instruction gets placed in its own
frag. It would trigger even with listing disabled though if the
instruction to swap a MIPS16 jump with was unfortunately enough placed
as last in a frag that became full.
This scenario is already handled correctly with branch swapping in
regular MIPS and microMIPS code, so reuse it for MIPS16 code as well,
and now that all MIPS16 handling has become the same as the regular MIPS
and microMIPS cases remove MIPS16 special casing altogether.
This effectively complements:

MIPS/GAS: Simplify non-MIPS16 branch swapping sequence
Simplify non-MIPS16 branch swapping by copying the MIPS16 variant, which
sets the new position for the current instruction first and reduces the
calculation of the new position of the previous instruction. Also refer
to previous instruction's frag and position via `delay' for consistency.

PR gas/20312: Do not pad sections to alignment on failed assembly
Correct a regression from commit 85024cd8bcb9 ("Run write_object_file
after errors") causing unsuccessful assembly, which may be due to any
reason, such as supplying a valid source like this:
.text
.byte 0
.err
to terminate with an assertion failure like:
test.s: Assembler messages:
test.s:3: Error: .err encountered
../as-new: BFD (GNU Binutils) 2.24.51.20140628 internal error, aborting at .../gas/write.c line 608 in size_seg
../as-new: Please report this bug.
on targets whose default text section alignment is above 0, typically
RISC machines.
This is due to an attempt to set last text section's frag alignment to
0, requested from `subsegs_finish_section' where `frag_align_code
(alignment, 0)' is called with `alignment' set to 0 rather than the
section alignment if `had_errors' has returned true. The call to
`subsegs_finish_section' is made from `subsegs_finish' from
`write_object_file' at unsuccessful completion, which previously wasn't
made.
Always set last section's frag alignment from the section alignment
then, forcing no section padding instead if completing unsuccessfully,
so that in that case alignment padding is still suppressed from any
listing generated, fixing assertion failures for these targets:

Fix gdbserver/MI testing regression
Commit 51f77c3704a6 ("Add testing infrastruture bits for running with
MI on a separate UI") broke MI testing with native-gdbserver:
$ make check RUNTESTFLAGS="--target_board=native-gdbserver mi-var-child.exp"
...
Running .../src/binutils-gdb/gdb/testsuite/gdb.mi/mi-var-child.exp ...
can't unset "inferior_spawn_id": no such variable
while executing
"unset inferior_spawn_id"
(procedure "close_gdbserver" line 20)
invoked from within
"close_gdbserver"
...
When testing with gdbserver, gdb_exit is overridden with a special
version that calls close_gdbserver, which clears inferior_spawn_id.
The problem is that the commit mentioned above made
gdb_exit/mi_gdb_exit clear inferior_spawn_id too, and clearing a
non-existing variable is a tcl error.
Since gdb_exit/mi_gdb_exit always clears inferior_spawn_id now, the
fix is simply to stop clearing it in close_gdbserver.

Fix gold testsuite failure with GCC 6.
With GCC 6 when not using -static-libstdc++, the operator delete(void*)
function is defined in the shared C++ support library, rather than in
the main program. The test script is too aggressive in checking for
this symbol's presence among the exported symbols. This patch removes
the check for that symbol.

PR gdb/17210 - fix possible memory leak in read_memory_robust
PR gdb/17210 concerns a possible memory leak in read_memory_robust.
The bug can happen because read_memory_robust allocates memory, does
not install any cleanups, and invokes QUIT. Similarly, target_read
calls QUIT, so it too can potentially throw.
The fix is to install cleanups to guard the allocated memory.
Built and regtested on x86-64 Fedora 23. I couldn't think of a way to
test this, so no new test; and of course this means it should have

gold: Support 386 TLS code sequences without PLT
There are extensions to 386 psABI:
https://groups.google.com/forum/#!topic/ia32-abi/awsRSvJOJfs
to call tls_get_addr via GOT:
call *___tls_get_addr@GOT(%reg)
where EBX register isn't required as GOT base.
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, 7-byte lea instruction before call
instruction is replaced by 6-byte one to make room for indirect call.
For local dynamic model, we simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction
patterns. For local dynamic model to local exec model transition,
we generate a 6-byte lea instruction as nop, instead of a 1-byte nop
plus a 4-byte lea instruction.

Initialize strtok_r's saveptr to NULL
Building gdb with --enable-build-with-cxx=no trips on a warning:
../../binutils-gdb/gdb/rust-lang.c:173:15: error: saveptr may be used
uninitialized in this function [-Werror=maybe-uninitialized]
ret.name = concat (TYPE_NAME (type), "::", token, (char *) NULL);
The problem is that gcc doesn't understand that "tail" can never be
NULL in the call to strtok_r:
name = xstrdup (TYPE_FIELD_NAME (type, 0));
cleanup = make_cleanup (xfree, name);
tail = name + strlen (RUST_ENUM_PREFIX);
...
for (token = strtok_r (tail, "$", &saveptr);
Fix this by always initializing saveptr.

Set unknown_syscall differently on arm linux
Currently, we use 123456789 as unknown or illegal syscall number, and
expect program return ENOSYS. Although 123456789 is an illegal syscall
number on arm linux, kernel sends SIGILL rather than returns -ENOSYS.
However, arm linux kernel returns -ENOSYS if syscall number is within
0xf0001..0xf07ff, so we can use 0xf07ff for unknown_syscall in test.

GAS: Fix `abort' expansion in write.c
Remove an internal diagnostic regression introduced with the inclusion of
"libbfd.h" from write.c, added with:

"as.h" earlier on, making the message produced by any calls reached from

.../gas/testsuite/gas/elf/type.s: Internal error, aborting at .../gas/write.c:602 in size_seg
Please report this bug.
With the removal of "libbfd.h" restore the latter message format.

[AArch64] Use int64_t for address offset
In AArch64 displaced stepping and fast tracepoint, GDB/GDBserver needs
to check whether the offset can fit in the range. We are using int32_t
for offset, it is sufficient to get an offset from an instruction, but
it is not enough to get an offset from two addresses. For example,
we have a BL in shared lib which is at 0x0000002000040774, and the
scratch pad for displaced stepping is at 0x400698. The offset can't
fit in 28 bit imm. However, since we are using int32_t for offset, GDB
thinks the offset can fit it, and generate the B instruction with wrong
offset.
It fixes the following fail,

Remove parameter sysret from linux_target_ops.get_syscall_trapinfo
When I implement linux_target_ops.get_syscall_trapinfo for aarch64 and arm,
I find the second parameter sysret isn't used at all. In RSP, we don't
need syscall return value either, because GDB can figure out the return
value from registers content got by 'g' packet.
This patch is to remove them.

Probe catch syscall support
In 82075af2c14b1f8a54fa5796fb63f7ef23f98d9d (Implement 'catch syscall'
for gdbserver), only x86 is supported, but the test can still be run
on other linux targets, like aarch64 and ppc, with native-gdbserver.
This causes many new fails.
This patch removes the check on isnative and on target triplets.
Instead, we can insert catch point, and resume the program to see whether
catch syscall is supported or not.

[AArch64] Make register indices be full 64-bit values
aarch64_opnd_info used bitfields to hold vector element indices,
but values were stored into those bitfields before their ranges had
been checked. This meant large invalid indices could be silently
truncated to smaller valid indices.
The two obvious fixes were to do the range checking earlier or use
a full 64-bit field for the index. I went for the latter for two
reasons:
- Doing the range checking in operand_general_constraint_met_p
seems structurally cleaner than doing it while parsing.
- The bitfields didn't really buy us anything. The imm field
of the union is already 128 bits, so we can use a full int64_t
index without growing the structure.
The patch also adds missing range checks for the elements in a register
list index.

* opcode/aarch64.h (aarch64_opnd_info): Change index fields to int64_t.

Print void types correctly in Rust
Rust prefers to not specify the return type of a function when it is unit
(`()`). The type is also referred to as "void" in debuginfo but not in actual
usage, so we should never be printing "void" when the language is Rust.

Fix use of a dangling pointer for Python breakpoint objects
When a Python script tries to create a breakpoint but fails to do so,
gdb.Breakpoint.__init__ raises an exception and the breakpoint does not
exist anymore in the Python interpreter. However, GDB still keeps a
reference to the Python object to be used for a later hook, which is
wrong.
This commit adds the necessary cleanup code so that there is no stale
reference to this Python object. It also adds a new testcase to
reproduce the bug and check the fix.

Support structure offsets that are 512K or larger.
GDB computes structure byte offsets using a 32 bit integer. And,
first it computes the offset in bits and then converts to bytes. The
result is that any offset that if 512K bytes or larger overflows.
This patch changes GDB to use LONGEST for such calculations.

MIPS16/GAS: Restore unsupported relocation diagnostics
Correct a MIPS16 relocation handling regression in GAS introduced with:
commit 177b4a6ad0047c8995fbc55016bc4f4b68d53b4a
Author: Alexandre Oliva <aoliva@redhat.com>
Date: Mon Mar 18 18:56:18 2002 +0000
discussed at <https://sourceware.org/ml/binutils/2002-03/msg00345.html>,
which removed a preparatory call to `mips16_extended_frag' previously
made from `md_estimate_size_before_relax'. As a result the function is
never called with its `sec' parameter non-NULL and consequently all the
unsupported relocation checks within are dead and never trigger, causing
any unhandled relocations to silently resolve to 0. Unfortunately there
was no sufficient test suite coverage back then to catch this.
Remove all dead code then, and all the associated comments. Update the
remaining call to `mips16_extended_frag' from `mips_relax_frag' to pass
the relocation section as the `sec' parameter and use it to mark frags
which require an external relocation, as extended. Finally handle any
outstanding MIPS16 relocations in `md_convert_frag' and report an error
since we don't support any except with percent operators.

Author: John Baldwin <jhb@FreeBSD.org>

Add support for catching system calls to native FreeBSD targets.
All platforms on FreeBSD use a shared system call table, so use a
single XML file to describe the system calls available on each FreeBSD
platform.
Recent versions of FreeBSD include the identifier of the current
system call when reporting a system call entry or exit event in the
ptrace_lwpinfo structure obtained via PT_LWPINFO in fbsd_wait. As
such, FreeBSD native targets do not use the gdbarch method to fetch
the system call code. In addition, FreeBSD register sets fetched via
ptrace do not include an equivalent of 'orig_rax' (on amd64 for
example), so the system call code cannot be extracted from the
available registers during a system call exit. However, GDB assumes
that system call catch points are not supported if the gdbarch method
is not present. As a workaround, FreeBSD ABIs install a dummy gdbarch
method that throws an internal_error if it is ever invoked.
gdb/ChangeLog:
* configure.ac: Check for support for system call LWP fields on
FreeBSD.
* config.in, configure: Rebuild.

Add a new gdbarch method to print a single AUXV entry.
Different platforms have different meanings for auxiliary vector
entries. The 'print_auxv_entry' gdbarch method allows an architecture
to output a suitable description for platform-specific entries.
A fprint_auxv_entry function is split out of fprint_target_auxv.
This function outputs the description of a single auxiliary vector
entry to the specified file using caller-supplied formatting and
strings to describe the vector type.
The existing switch on auxiliary vector types is moved out of
fprint_target_auxv into a new default_print_auxv_entry function.
default_print_auxv_entry chooses an appropriate format and description
and calls fprint_single_auxv to describe a single vector entry.
This function is used as the default 'print_auxv_entry' gdbarch method.
fprint_target_auxv now invokes the gdbarch 'print_auxv_entry' method
on each vector entry.
gdb/ChangeLog:
* auxv.c (fprint_auxv_entry): New function.
(default_print_auxv_entry): New function.
(fprint_target_auxv): Use gdbarch_print_auxv_entry.

fix undefined reference to bfd_link_plugin_object_p during link
When configured with the default options, GDB currently fails to link,
due to an undefined reference to bfd_link_plugin_object_p, coming from
elflink.c:
#ifdef BFD_SUPPORTS_PLUGINS
|| (abfd->plugin_format == bfd_plugin_unknown
&& bfd_link_plugin_object_p (abfd))
#endif
This is because BFD_SUPPORTS_PLUGINS is always defined. It is its value
that determines whether plugin support is enabled or not.
bfd/ChangeLog:
* elflink.c: Check the value of BFD_SUPPORTS_PLUGINS rather
than its existance.

MIPS objcopy --rename-section fix
Some MIPS targets use a named section symbol rather than a symbol with
no name as is used with most ELF targets. When renaming sections, the
named section symbol needs to be renamed too.
Rather than fix this bug, I'd originally intended to just correct the
xfail added recently for update-1.o vs update4.o in update-section.exp,
using the same set of targets for the localize-hidden-1 mips xfail.
I'd extracted that target test into a new function, is_bad_symtab. It
turns out to be useful in readelf.exp too.

Move logic out of symbol_find_demangled_name
This patch moves most of the demangling logic out of
symbol_find_demangled_name into the various language_defn objects.
The simplest way to do this seemed to be to add a new method to
language_defn. This is shame given the existing la_demangle, but
given Ada's unusual needs, and the differing demangling options
between languages, la_demangle didn't seem to fit.
In order to make this work, I made enum language order-sensitive.
This helps preserve the current ordering of demangling operations.

PR gdb/16483 - simplify "info frame-filters" output
PR gdb/16483 notes that the output of "info frame-filters" is quite
voluminous. In particular it prints an entry for each objfile, even if
only to say that the objfile does not have any associated frame filters.
I think it's better to only print output when there is a frame filter.
There's nothing worth doing with the no-frame-filter information, and
limiting the output makes it much more readable.

[ARC] Misc minor edits/fixes
The code supporting -mspfp, -mdpfp, and -mfpuda options are in
sections of code that are commented as being for backward
compatibility only, and having no effect. However, they do have an
effect, enabling the SPX, DPX, and DPA instruction subclasses
respectively. This commit moves the code supporting these options
away from the comments indicating that they are dummy options, and
also fixes a small issue where -mnps400 had the additional effect
of enabling SPX instructions.
A couple of other minor edits (that make no functional change) are
also included.
gas/ChangeLog:
* config/tc-arc.c (options, md_longopts, md_parse_option):
Move -mspfp, -mdpfp and -mfpuda out of the sections for
dummy options. Correct erroneous enabling of SPFP

MIPS/GAS: Correct BFD_RELOC_MIPS_18_PCREL_S3 calculation
The PC-relative R_MIPS_PC18_S3 relocation and consequently its BFD
internal BFD_RELOC_MIPS_18_PCREL_S3 representation is calculated from
the address of the aligned doubleword containing the location being
relocated: (sign_extend(A) + S - (P & ~0x7)) >> 3 rather than the
address of the location itself. Reflect this in calculations made by
GAS so that the relocated field is set correctly if resolved by GAS,
such as with local symbols in the same section which do not require
relocations to be propagated to the link stage.

MIPS/GAS: Use the module level ISA setting for R6 relaxation
Use the module level ISA setting rather than the last ISA selected with
a `.set' directive in the source file in determination as to whether to
keep PC-relative relocations and then with the original symbol referred,
for the purpose of R6 linker relaxation.
This is so that with e.g. code like this:
b foo
.set mips32r2
...
it's the command line options or any `.module' directive that decides
how to encode any relocation for `foo' rather than the presence of `.set
mips32r2'.

Add "new-ui console" tests
This adds a test that uses new-ui to create a secondary console, and
then runs some basic smoke tests. It ensures that:
- synchronous commands send output to the UI that initiated it
- asynchronous events like breakpoint hits are reported on all
consoles.
- "new-ui" without arguments doesn't crash.
- The "new-ui" command doesn't repeat.

Always switch fork child to the main UI
The following scenario:
- gdb started in normal CLI mode.
- separate MI channel created with new-ui
- inferior output redirected with the "set inferior-tty" command.
- use -exec-run in the MI channel to run the inferior
is presently mishandled.
When we create the inferior, in fork-child.c, right after vfork, we'll
close all the file descriptors in the vfork child, and then dup the
tty to file descriptors 0/1/2, create a session, etc. Note that when
we close all descriptors, we close the file descriptors behind
gdb_stdin/gdb_stdout/gdb_stderr of all secondary UIs... So if
anything goes wrong in the child and it calls warning/error, it'll end
up writting to the current UI's stdout/stderr streams, which are
backed by file descriptors that have since been closed. Because this
happens in a vfork region, the corresponding stdin/stdout/stderr in
the parent/gdb end up corrupted.
The fix is to switch to the main UI right after the vfork, so that
gdb_stdin/gdb_stdout/gdb_stderr are correctly mapped to
stdin/stdout/stderr (and thus to file descriptors 0/1/2), so this code
works as it has always worked.
(Technically, we're doing a lot of stuff we shouldn't be doing after a
vfork, while we should only be calling async-signal-safe functions.)

Make mi-break.exp always expect breakpoint commands output on the main UI
mi-break.exp regresses when tested with MI running on a secondary UI,
with RUNTESTFLAGS="FORCE_SEPARATE_MI_TTY=1".
The problem is simply that the test sets a breakpoint, and attaches
"print" commands to the breakpoint. Since breakpoint commands always
run with the main UI as current UI, the breakpoint command's output
goes to the main UI. So we need to tweak the test to expect it there.

Add testing infrastruture bits for running with MI on a separate UI
With this, a specific test may can start GDB with MI on a separate UI
by using:
mi_gdb_start separate-mi-tty
In addition, it's also possible to run the whole testsuite with MI on
a separate tty, with:
make check RUNTESTFLAGS="FORCE_SEPARATE_MI_TTY=1"
gdb_main_spawn_id and mi_spawn_id are added so that tests may expect
output from either channel.
While at it, inferior_spawn_id was not being cleared when gdb exits,
unlike the other spawn ids, thus a test that starts gdb more than once

Add new command to create extra console/mi UIs
With all the previous plumbing in place, it's now easy to add a
command that actually creates a new console/mi UI.
The intended use case is to make it possible and easy for MI frontends
to provide a fully featured GDB console to users, with readline
support, command line editing, history, etc., just like if gdb was
started on the command line. Currently MI frontends have to try to
implement all of that theirselves and make use of "-interpreter-exec
console ...", which is far from perfect. If you ever tried Eclipse's
gdb console window, you'll know what I mean...
Instead of trying to multiplex console through MI, this command let's
just leverage all the built in readline/editing support already inside
gdb.
The plan is for the MI frontend to start GDB in regular console mode,
running inside a terminal emulator widget embedded in Eclipse (which
already exists, for supporting the shell widget; other frontends have
similar widgets), and then tell GDB to run a full MI interpreter on an
specified input/output device, independent of the console.
My original prototype planned to do things the other way around --
start GDB in MI mode, and then start an extra CLI console on separate
tty. I handed over that prototype to Marc Khouzam @ Eclipse CDT, and
after experimentation and discussion, we ended up concluding that
starting GDB in CLI mode instead was both easier and actually also
supported an interesting use case -- connect an Eclipse frontend to a
GDB that is already running outside Eclipse.
The current usage is "new-ui <interpreter> <tty>".
E.g., on a terminal run this scriplet:
$ cat gdb-client
#!/bin/bash
reset
tty
tail -f /dev/null
$ gdb-client
/dev/pts/15
Now run gdb on another terminal, and tell it to start a MI interpreter
on the tty of the other terminal:
...
(gdb) new-ui mi /dev/pts/15
New UI allocated
Now back to the the gdb-client terminal, we'll get an MI prompt, ready
for MI input:
/dev/pts/15
=thread-group-added,id="i1"
(gdb)
You can also start a new UI running a CLI, with:
(gdb) new-ui console /dev/pts/15
Though note that this console won't support readline command editing.
It works as if "set editing off" was entered.

Make stdin be per UI
This commit makes each UI have its own "stdin" stream pointer. This
is used to determine whether the "from_tty" argument to
execute_command, etc. should be true.
Related, this commit makes input_from_terminal_p take an UI parameter,
and then avoids the gdb_has_a_terminal in it. gdb_has_a_terminal only
returns info on gdb's own main/primary terminal (the real stdin).
However, the places that call input_from_terminal_p really want to
know is whether the command came from an interactive tty. This patch
thus renames input_from_terminal_p to input_interactive_p for clarity,
and then makes input_interactive_p check for "set interactive" itself,
along with ISATTY, instead of calling gdb_has_a_terminal. Actually,
quit_force wants to call input_interactive_p _after_ stdin is closed,
we can't call ISATTY that late. So instead we save the result of
ISATTY in a field of the UI.

Make main_ui be heap allocated
This is preparation for being able to create more than one UI object.
The change to gdb_main to stop using catch_errors is necessary because
catch_errors references current_uiout, which expands to

Currently when a "step", "next", etc. finishes, the current source

Push thread->control.command_interp to the struct thread_fsm
I noticed that if we step into an inline function, step_1 never
reaches proceed, and thus nevers sets the thread's
tp->control.command_interp. Because of that,
should_print_stop_to_console fails to determine that is should print
stop output to the console.
The fix is to set the thread's command_interp earlier. However, I
realized that we can move that field to the thread_fsm, given that its
lifetime is exactly the same as thread_fsm. So the patch plumbs all
fsms constructors to take the command interp and store it in the
thread_fsm.
We can see the fix in action, with e.g., the gdb.opt/inline-cmds.exp
test, and issuing a step when stopped at line 67:

FAIL: gdb.mi/mi-break.exp: intermediate stop and continue
FAIL: gdb.mi/mi-break.exp: test hitting breakpoint with commands (timeout)
Note the line marked >> above.
The test sets a breakpoint that runs "continue", a foreground command.
When we get to run the "continue", we've already emitted the *stopped
event on the MI UI, and set its prompt state to PROMPT_NEEDED (this is
done from within normal_stop). Since inferior events are always
handled with the main UI as current UI, breakpoint commands always run
with the main UI as current UI too. This means that the "continue"
ends up always disabling the prompt on the main UI, instead of the UI
that had just been done with synchronous execution.
I think we'll want to extend this with a concept of "set of
threads/inferiors a UI/interpreter is blocked waiting on", but I'm
leaving that for a separate series.

Replace the sync_execution global with a new enum prompt_state tristate
When sync_execution (a boolean) is true, it means we're running a
foreground command -- we hide the prompt stop listening to input, give
the inferior the terminal, then go to the event loop waiting for the
target to stop.
With multiple independent UIs, we need to track whether each UI is
synchronously blocked waiting for the target. IOW, if you do
"continue" in one console, that console stops accepting commands, but
you should still be free to type other commands in the others
consoles.
Just simply making sync_execution be per-UI alone not sufficient,
because of this in fetch_inferior_event:
/* If the inferior was in sync execution mode, and now isn't,
restore the prompt (a synchronous execution command has finished,
and we're ready for input). */
if (current_ui->async && was_sync && !sync_execution)
observer_notify_sync_execution_done ();
We'd have to record at entry the "was_sync" state for each UI, not
just of the current UI.
This patch instead replaces the sync_execution flag by a per-UI
tristate flag indicating the command line prompt state:
enum prompt_state
{
/* The command line is blocked simulating synchronous execution.
This is used to implement the foreground execution commands
('run', 'continue', etc.). We won't display the prompt and
accept further commands until the execution is actually over. */
PROMPT_BLOCKED,
/* The command finished; display the prompt before returning back to
the top level. */
PROMPT_NEEDED,
/* We've displayed the prompt already, ready for input. */
PROMPTED,
;
I think the end result is _much_ clearer than the current code, and,
it addresses the original motivation too.

Simplify starting the command event loop
All interpreter types (CLI/TUI/MI) print the prompt, and then call
start_event_loop.
Because we'll need an interpreter hook to display the
interpreter-specific prompt before going back to the event loop,
without actually starting an event loop, this patch moves the
start_event_loop call to common code, and replaces the command_loop
hook with a pre_command_look hook, that now just prints the prompt.
Turns out to be a cleanup on its own right anyway.

Make command line editing (use of readline) be per UI
Due to the way that readline's API works (based on globals), we can
only have one instance of readline in a process. So the goal of this
patch is to only allow editing in the main UI, and make sure that only
one UI calls into readline. Some MI paths touch readline variables
currently, which is bad as that is changing variables that matter for
the main console UI. This patch fixes those.
This actually fixes a nasty bug -- starting gdb in MI mode ("gdb
-i=mi"), and then doing "set editing on" crashes GDB, because MI is
not prepared to use readline:
set editing on
&"set editing on\n"
=cmd-param-changed,param="editing",value="on"
^done
(gdb)
p 1
readline: readline_callback_read_char() called with no handler!

Currently, current_uiout starts out pointing to def_uiout, a dummy

Since we create a replacement uiout early on as soon as we create the

it.

Make the intepreters output to all UIs
When we have multiple consoles, MI channels, etc., then we need to
broadcast breakpoint hits, etc. to all UIs. In the past, I've
adjusted most of the run control to communicate events to the
interpreters through observer notifications, so events would be
properly sent to console and MI streams, in sync and async modes.
This patch does the next logical step -- have each interpreter's
observers output interpreter-specific info to _all_ UIs.
Note that when we have multiple instances of active cli/tui
interpreters, then the cli_interp and tui_interp globals no longer
work. This is addressed by this patch.
Also, the interpreters currently register some observers when resumed
and remove them when suspended. If we have multiple instances of the
interpreters, and they can be suspended/resumed at different,
independent times, that no longer works. What we instead do is always
install the observers, and then have the observers themselves know
when to do nothing.
An earlier prototype of this series did the looping over struct UIs in
common code, and then dispatched events to the interpreters through a
matching interp_on_foo method for each observer. That turned out a
lot more complicated than the present solution, as we'd end up with
having to create a new interp method every time some interpreter
wanted to listen to some observer notification, resulting in a lot of
duplicated make-work and more coupling than desirable.

Introduce interpreter factories
If every UI instance has its own set of interpreters, then the current
scheme of creating the interpreters at GDB initialization time no
longer works. We need to create them whenever a new UI instance is
created.
The scheme implemented here has each interpreter register a factory
callback that when called creates a new instance of a specific
interpreter type. Then, when some code in gdb looks up an interpreter
(always by name), if there's none yet, the factory method is called to
construct one.

Make the interpreters be per UI
Make each UI have its own interpreter list, top level interpreter,
current interpreter, etc. The "interpreter_async" global is not

left hidden in interps.c, opaque to the rest of GDB.

Make gdb_stdout&co be per UI
We need to have these send output to the proper UI.
However, this patch still make them look like globals. Kind of like
__thread variables, if you will. Changing everything throughout to
write something like current_ui->gdb_stdout instead would be massive
overkill, IMNSHO.
This leaves gdb_stdtargin/stdtarg/stdtargerr global, but maybe that was a
mistake, I'm not sure -- IIRC, MI formats target I/O differently, so
if we have a separate MI channel, then I guess target output should go
there instead of to gdb's stdout. OTOH, maybe GDB should send that
instead to "set inferior-tty", instead of multiplexing it over MI. We
can always fix those later when it gets clearer where they should go.

Introduce "struct ui"
This is a step towards supporting multiple consoles/MIs, each on its
own stdio streams / terminal.
See intro comment in top.h.
(I've had trouble picking a name for this object. I've started out
with "struct console" originally. But then this is about MI as well,
and there's "interpreter-exec console", which is specifically about
the CLI...
So I changed to "struct terminal", but, then we have a terminal object
that works when the input is not a terminal as well ...
Then I sort of gave up and renamed it to "struct top_level". But it
then gets horribly confusing when we talk about the "top level
interpreter that's running on the current top level".
In the end, I realized we're already sort of calling this "ui", in
struct ui_out, struct ui_file, and a few coments here and there.)

PASS: gdb.ada/mi_catch_ex.exp: continue until CE caught by all-exceptions catchpoint
The problem is that:
- MI prints the breakpoint hit twice: once on the MI stream;
another time on the console stream.
- After printing the Ada catchpoint hit, gdb selects a non-current
frame, from within the catchpoint's print_it routine.
So the second time the breakpoint is printed, the selected frame is no
longer the current frame, and then evaluating e.full_name in
ada_exception_name_addr fails.
This commit fixes the problem and enhances the gdb.ada/mi_catch_ex.exp
test to make sure the catchpoint hit is printed correctly on the
console stream too.

Prepare gdb.python/mi-py-events.exp for Python/MI in separate channels
Similarly to 5068630ad34dce5fefbe68d70d3a50cd8b92f71e
(gdb.python/py-events.exp and normal_stop observers ordering) [1],
this commit makes the gdb.python/py-mi-events.exp test not rely on
order in which MI and Python observers run, or even on where each
observer sends its output to.
This shows up as a problem when testing with MI running as a separate
terminal, for example, where Python event output and MI output go to
different channels, even. But in any case, relying on the order in
which observers run is always going to be fragile.
The fix is to save the string output in the handlers in some variables
and then having MI print them explicitly, instead of printing them
directly from the Python events.
Tested on x86_64 Fedora 23.

Use the IR symbol table for the IR input object
ELF linker shouldn't skip the IR object when searching the symbol table
of an archive element. If linker doesn't know if the object file is an

table and use the IR symbol table if the input is an IR object.

Don't generate PLT for IFUNC GOT/pointer reference
If a backend supports it, PLT entry isn't needed when all references
to a STT_GNU_IFUNC symbols are done via GOT or static function pointers.
For GOT entries, We generate dynamic R_*_GLOB_DAT relocations for
preemptable symbols and R_*_IRELATIVE relocations for non-preemptable
symbols to update them with real function address. For static pointer
pointers, we generate dynamic pointer relocations and store them in:
1. .rel[a].ifunc section in PIC object.
2. .rel[a].got section in dynamic executable.
3. .rel[a].iplt section in static executable.
We don't allocate GOT entry if it isn't used.

Handle reinsert breakpoints for vforked child
When a thread is doing step-over with reinsert breakpoint, and the
instruction executed is a syscall doing vfork, both parent and child
share the memory, so the reinsert breakpoint in the space is visible
to both of them. Also, removing the reinsert breakpoints from the
child will effectively remove them from the parent. We should
carefully manipulate reinsert breakpoints for both processes.
What we are doing here is that
- uninsert reinsert breakpoints from the parent before cloning the
breakpoint list. We use "uninsert" instead of "remove", because
we need to "reinsert" them back after vfork is done. In fact,
"uninsert" removes them from both child and parent process space.
- reinsert breakpoints in parent process are still copied to child's
breakpoint list,
- remove them from child's breakpoint list as what we did for fork,
at this point, reinsert breakpoints are removed from the child and
the parent, but they are still tracked by the parent's breakpoint
list,
- once vfork is done, "reinsert" them back to the parent,

Delete reinsert breakpoints from forked child
When a thread is stepping over a syscall instruction with software
single step, GDBserver inserts reinsert breakpoints at the next pcs.
If the syscall call is fork, the forked child has reinsert breakpoint
in its space, and GDBserver clones parent's breakpoint list to child's.
When GDBserver resumes the child, its bp_reinsert is zero, but has
reinsert breakpoints, so the following assert is triggered if I apply
the patch extending step-over-syscall.exp.

Step over exit with reinsert breakpoints
This patch fixes a GDBserver crash when one thread is stepping over
a syscall instruction which is exit. Step-over isn't finished due
to the exit, but GDBserver doesn't clean up the state of step-over,
so in the wait next time, GDBserver will wait on step_over_bkpt,
which is already exited, and GDBserver crashes because
'requested_child' is NULL. See gdbserver logs below,

The fix is to finish step-over if it is ongoing, and unsuspend other
threads. Without the fix in linux-low.c, GDBserver will crash in
with running gdb.base/step-over-exit.exp.

Switch to current thread in finish_step_over
This patch adds some sanity check that reinsert breakpoints must be
there when doing step-over on software single step target. The check
triggers an assert when running forking-threads-plus-breakpoint.exp
on arm-linux target,
gdb/gdbserver/linux-low.c:4714: A problem internal to GDBserver has been detected.^M
int finish_step_over(lwp_info*): Assertion `has_reinsert_breakpoints ()' failed.
the error happens when GDBserver has already resumed a thread of
process A for step-over (and wait for it hitting reinsert breakpoint),
but receives detach request for process B from GDB, which is shown in
the backtrace below,

the sanity check tries to find the reinsert breakpoint from process B,
but nothing is found. It is wrong, we need to search in process A,
since we started step-over of a thread of process A.

opcodes,gas: adjust sparc insns and make GAS aware of it
This patch marks the SPARC instructions in the opcodes table with their
proper opcode architectures, and makes the assembler aware of them.
This allows the assembler to properly realize when a new instruction
needs a higher architecture (after v9b) and to react accordingly
emitting an error message or bumping the architecture.
It also expands architecture mismatch tests to cover architectures
higher than v9b, and fixes a couple of minor bugs in the GAS testsuite.

gas: sparc: fix collision of registers and pseudo-ops.
The current sparc assembler breaks when the name of an ancillary-state
register, privileged register or hyperprivileged register has a
%-pseudo-operation name as a prefix. For example, %hmcdper and %hm(),
or %hintp and %hi().
This patch fixes it by introducing a new table `perc_table' (for
%-table) that contains an entry for every %name supported by the
assembler, other than the general registers. This table is used to
detect name collisions when the assembler tries to detect a %-pseudo-op.
This patch also fixes a related bug, making sure that v9a_asr_table and
hpriv_reg_table are sorted in reverse lexicographic order, as otherwise
the search code may fail.

bfd,opcodes: sparc: new opcode v9{c,d,e,v,m} architectures and bfd machine numbers.
This patch adds support for the opcode architectures
SPARC_OPCODE_ARCH_V9{C,D,E,V,M} and its associated BFD machine numbers
bfd_mach_sparc_v9{c,d,e,v,m} and bfd_mach_sparc_v8plus{c,d,e,v,m}.
Note that for arches up to v9b (UltraSPARC III), the detection of the
BFD machine type was based on the bits in the e_machine field of the ELF
header. However, there are no more available bits in that field, so
this patch takes the approach of using the hardware capabilities stored
in the object attributes HWCAPS/HWCAPS2 in order to characterize the
machine the object was built for.

Skip relocations in non-loaded, non-alloced sections

In particular, any relocs in such sections should not affect GOT

relocs, and there's not much point in propagating relocs to shared

gdb: Use UNSUPPORTED not XFAIL for unsupported target features
If a target does not support making function calls from GDB then in a
number of test files, we currently report an XFAIL and skip some, or all
of the tests. This commit changes the XFAIL to an UNSUPPORTED as this
seems more appropriate in these cases.
Some of the tests used bug ID 2416 to be reported in the XFAIL. In the
current GDB bugzilla bug 2416 has nothing to do with calling target
functions from GDB.

S/390: Dump unknown instructions according to their length.
Unknown instructions are currently just dumped as .long 1234. On
S/390 we can do a bit better since the instruction length is encoded
in the opcode. That way also unknown instructions can be skipped
according to their real length. That way we can continue correctly
after that instruction. However, there are also some drawbacks with
that behavior when dumping data. So for now that behavior is only
enabled for text section but even there it might mess things up when
having a literal pool embedded in the code. Therefore I've left the
feature disabled by default and have added the -Minsnlength option to
enable it explicitely.

i386: Test external function reference without PLT
To call an external function, the direct branch to the PLT entry can be
replaced by an indirect branch via the GOT slot, which is similar to the
first instruction in the PLT slot. Instead using the PLT slot as function
address, the function address is retrieved from the GOT slot. The
R_386_GOT32X relocation can be used to compute the address of the symbol’s
GOT entry without base register when PIC is disabled. In non-PIC
executable,
call/jmp *func@GOT
should be used for indirect branch via the GOT slot and
movl func@GOT, %eax
should be used to load function address. Unlike PIC case, no register
is needed to access GOT. If linker determines the function is defined
locally, it converts indirect branch via the GOT slot to direct branch
with a nop prefix and converts load via the GOT slot to load immediate
or lea.

Support i386 TLS code sequences without PLT
We can generate i386 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:
call *___tls_get_addr@GOT(%reg)
where EBX register isn't required as GOT base, instead of direct call:
call ___tls_get_addr[@PLT]
which requires EBX register as GOT base.
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, 7-byte lea instruction before call instruction
is replaced by 6-byte one to make room for indirect call. For local
dynamic model, we simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
a 6-byte lea instruction as nop, instead of a 1-byte nop plus a 4-byte
lea instruction. Since linker may convert
call ___tls_get_addr[@PLT]
to
addr32 call ____tls_get_addr
when producing static executable, both patterns are recognized.

PowerPC VLE
VLE is an encoding, not a particular processor architecture, so it
isn't really proper to select insns based on PPC_OPCODE_VLE. For
example
{"evaddw", VX (4, 512), VX_MASK, PPCSPE|PPCVLE, PPCNONE, {RS, RA, RB}},
{"vaddubs", VX (4, 512), VX_MASK, PPCVEC|PPCVLE, PPCNONE, {VD, VA, VB}},
shows two insns that have the same encoding, both available with VLE.
Enabling both with VLE means we can't disassemble the second variant
even if -Maltivec is given rather than -Mspe. Also, we don't check
user assembly against the processor type as well as we could.
Another problem is that when using the VLE encoding, insns from the
main ppc opcode table are not available, except those using opcode 4
and 31. Correcting this revealed two errors in the ld testsuite,
use of "nop" and "rfmci" when -mvle.
This patch fixes those problems in the opcode table, and removes
PPCNONE. I find a plain 0 distracts less from other values.
In addition, I've implemented code to recognize some machine values
from the apuinfo note present in ppc32 objects. It's not a complete
disambiguation since we're lacking info to detect newer chips, but
what we have should help with disassembly.

Add method/format information to =record-started
Eclipse CDT now supports enabling execution recording using two methods
(full and btrace) and both formats for btrace (bts and pt). In the
event that recording is enabled behind the back of the GUI (by the user
on the command line, or a script), we need to know which method/format
are being used, so it can be correctly reflected in the interface. This
patch adds this information to the =record-started async record.
Before:
=record-started,thread-group="i1"
After:
=record-started,thread-group="i1",method="btrace",format="bts"
=record-started,thread-group="i1",method="btrace",format="pt"
=record-started,thread-group="i1",method="full"
The "format" field is only present when the current method supports
multiple formats (only the btrace method as of now).

Support x86-64 TLS code sequences without PLT
We can generate x86-64 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:

For general dynamic model, one 0x66 prefix before call instruction is
removed to make room for indirect call. For local dynamic model, we
simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
4 0x66 prefixes, instead of 3, before mov instruction in 64-bit and
generate a 5-byte nop, instead of 4-byte, before mov instruction in
32-bit. Since linker may convert
call *__tls_get_addr@GOTPCREL(%rip)
to
addr32 call __tls_get_addr
when producing static executable, both patterns are recognized.

being set up.

avr: replace sentinal with iteration from 0 to ARRAY_SIZE
This seems a little easier to understand than using a sentinal, and will

gdb/remote-fileio.c: Eliminate custom SIGINT signal handler
... and fix Ctrl-C races.
The current remote-fileio.c SIGINT/EINTR code can lose Ctrl-C --
there's a period where SIG_IGN is installed as signal handler, for
example.
Since:
- remote.c no longer installs a custom SIGINT handler;
- The current remote-fileio.c SIGINT handler is basically the same as
the default SIGINT handler (event-top.c:handle_sigint), in
principle, except that instead of setting the quit flag, it sets a
separate flag.
I think we should be able to completely remove the remote-fileio.c
SIGINT handler, and centralize on the quit flag, thus fixing the
Ctrl-C race.

infcmd, btrace: fix crash in 'finish' for tailcall-only frames
Patch 7eb895307f53 Skip unwritable frames in command "finish"
skips non-writable frames in addition to tailcall frames.
If skip_tailcall_frames already returns NULL, skip_unwritable_frames
will be called with a NULL frame and crash in get_frame_arch. This is
caught by gdb.btrace/tailcall-only.exp.
Further, if we ever end up with a mixture of tailcall and non-writable
frames, we may not skip all of them, as intended.
Loop over skip_tailcall_frames and skip_unwritable_frames as long as at least
one of them makes progress.

Wake up interruptible_select in remote_fileio ctrl-c handler
As reported in PR 19998, after type ctrl-c, GDB hang there and does
not send interrupt. It causes a fail in gdb.base/interrupt.exp.
All targets support remote fileio should be affected.
When we type ctrc-c, SIGINT is handled by remote_fileio_sig_set,
as shown below,
#0 remote_fileio_sig_set (sigint_func=0x4495d0 <remote_fileio_ctrl_c_signal_handler(int)>) at /home/yao/SourceCode/gnu/gdb/git/gdb/remote-fileio.c:325

we don't set quit_serial_event,
do
{
res = gdb_select (n, readfds, writefds, exceptfds, timeout);
}
while (res == -1 && errno == EINTR);
if (res == 1 && FD_ISSET (fd, readfds))
{
errno = EINTR;
return -1;
}
return res;
we can't go out of the loop above, and that is why GDB can't send
interrupt.
Recently, we stop throwing exception from SIGINT handler
(remote_fileio_ctrl_c_signal_handler)
https://sourceware.org/ml/gdb-patches/2016-03/msg00372.html, which
is correct, because gdb_select is interruptible. However, in the
same patch series, we add interruptible_select later as a wrapper
to gdb_select, https://sourceware.org/ml/gdb-patches/2016-03/msg00375.html
and it is not interruptible (because of the loop in it) unless
select/poll-able file descriptors are marked.
This fix in this patch is to call quit_serial_event_set, so that we can
go out of the loop above, return -1 and set errno to EINTR.

[PR gdb/19893] Fix handling of synthetic C++ references
https://sourceware.org/bugzilla/show_bug.cgi?id=19893
I've traced the main source of the problem to pieced_value_funcs.coerce_ref not being
implemented. Since gdb always assumes references are implemented as pointers, this
causes it to think that it's dealing with a NULL pointer, thus breaking any operations
involving synthetic references.
What I did here was implementing pieced_value_funcs.coerce_ref using some of the synthetic
pointer handling code from indirect_pieced_value, as Pedro suggested. I also made a few
adjustments to the reference printing code so that it correctly shows either the address
of the referenced value or (if it's non-addressable) the "<synthetic pointer>" string.
I also wrote some unit tests based on Dwarf::assemble; these took a while to make
because in most cases I needed a synthetic reference to a physical variable. Additionally,
I started working on a unit test for classes that have a vtable, but ran into a few issues
so that'll probably go in a future patch. One thing that should definitely be fixed is that
proc function_range (called for MACRO_AT_func) will always try to compile/link using gcc
with the default options instead of g++, thus breaking C++ compilations that require e.g. libstdc++.

All emit calls have been tested using asserts before / after the move, to

emit_gt_goto, emit_lt_goto, emit_pop, emit_unsigned_less.

Add counter-cases for trace-condition.exp tests
In trace-condition.exp, tests are done by doing a conditional tracepoint
and validating that the trace contains all the frames that could be
collected if that condition is true.
E.g. test_tracepoints $trace_command "21 + 21 == 42" 10
This will always return true and collect the 10 frames possible to collect
with the test program.
However, if the condition evaluation is broken such that the condition is
unconditional we will not notice this problem.
This patch adds counter-cases to such conditions like so:
$trace_command "21 + 11 == 42" 0
This way such a problem would be noticed.
gdb/testsuite/ChangeLog:
* gdb.trace/trace-condition.exp: Add counter-case tests.

MIPS/BFD: Enable local R_MIPS_26 overflow detection
The original MIPS SVR4 psABI defines the calculation for the R_MIPS_26
relocation in a complex way, as follows[1]:
Name Value Field Symbol Calculation
R_MIPS_26 4 T-targ26 local (((A << 2) | \
(P & 0xf0000000)) + S) >> 2
4 T-targ26 external (sign-extend(A << 2) + S) >> 2
This is further clarified, by correcting typos (already applied in the
excerpt above) in the 64-bit psABI extension[2]. A note is included in
both documents to specify that for the purpose of relocation processing
a local symbol is one with binding STB_LOCAL and type STT_SECTION, and
otherwise, a symbol is external.
We have both calculations implemented for the R_MIPS_26 relocation, and
by extension also for the R_MIPS16_26 and R_MICROMIPS_26_S1 relocations,
from now on collectively called jump relocations. However our code uses
a different condition to tell local and external symbols apart, that is
it only checks for the STB_LOCAL binding and ignores the symbol type,
however for REL relocations only. The external calculation is used for
all RELA jump relocations.
In reality the difference matters for jump relocations referring local
MIPS16 and, as from recent commit 44d3da233815 ("MIPS/GAS: Treat local
jump relocs the same no matter if REL or RELA"), also local microMIPS
symbols. Such relocations are not converted to refer to corresponding
section symbols instead and retain the original local symbol reference.
It can be inferred from the relocation calculation definitions that the
addend is effectively unsigned for the local case and explicitly signed
for the external case. With the REL relocation format it makes sense
given the limited range provided for by the field being relocated: the
use of an unsigned addend expands the range by one bit for the local
case, because a negative offset from a section symbol makes no sense,
and any usable negative offset from the original local symbol will have
worked out positive if converted to a section-relative reference. In
the external case a signed addend gives more flexibility as offsets both
negative and positive can be used with a symbol. Any such offsets will
typically have a small value.
The inclusion of the (P & 0xf0000000) component, ORed in the calculation
in the local case, seems questionable as bits 31:28 are not included in
the relocatable field and are masked out as the relocation is applied.
Their value is therefore irrelevant for output processing, the relocated
field ends up the same regardless of their value. They could be used
for overflow detection, however this is precluded by adding them to bits
31:28 of the symbol referred, as the sum will not correspond to the
value calculated by the processor at run time whenever bits 31:28 of the
symbol referred are not all zeros, even though it is valid as long they
are the same as bits 31:28 of P.
We deal with this problem by ignoring any overflow resulting from the
local calculation. This however makes us miss genuine overflow cases,
where 31:28 of the symbol referred are different from bits 31:28 of P,
and non-functional code is produced.
Given the situation, for the purpose of overflow detection we can change
our code to follow the original psABI and only treat the in-place addend
as unsigned in the section symbol case, permitting jumps to offsets
128MiB and above into section. Sections so large may be uncommon, but
still a reasonable use case. On the other hand such large offsets from
regular local symbols are not expected and it makes sense to support
(possibly small) negative offsets instead, also in consistency with what
we do for global symbols.
Drop the (P & 0xf0000000) component then, treat the addend as signed
with local non-section symbols and also detect an overflow in the result
of such calculation with local symbols. NB it does not affect the value
computed for the relocatable field, it only affects overflow detection.

Return void from linker callbacks
The ldmain.c implementation of these linker callback functions always
return true, so any code handling a false return is dead. What's
more, some of the bfd backends abort if ever a false return is seen,
and there seems to be some confusion in gdb's compile-object-load.c.
The return value was never meant to be "oh yes, a multiple_definition
error occurred", but rather "out of memory or other catastrophic
failure".
This patch removes the status return on the callbacks that always
return true. I kept the return status for "notice" because that one
does happen to need to return "out of memory".

MIPS/BFD: Fix section symbol name fetching in relocation
Symbol table entries for section symbols are different between IRIX and
traditional MIPS ELF targets in that IRIX entries have their `st_name'
member pointing at the section's name in the string table section, while
traditional entries have 0 there and the section header string table has
to be referred via the relevant section header's `shn_name' member
instead.
This is chosen with the `elf_backend_name_local_section_symbols' backend
and can be observed with `readelf -s' output for an IRIX object:
Symbol table '.symtab' contains 12 entries:
Num: Value Size Type Bind Vis Ndx Name
0: 00000000 0 NOTYPE LOCAL DEFAULT UND
1: 00000000 0 SECTION LOCAL DEFAULT 1 .text
2: 00000000 0 SECTION LOCAL DEFAULT 3 .data
3: 00000000 0 SECTION LOCAL DEFAULT 4 .bss
4: 00000000 0 SECTION LOCAL DEFAULT 5 .reginfo
5: 00000000 0 SECTION LOCAL DEFAULT 6 .MIPS.abiflags
6: 00000000 0 SECTION LOCAL DEFAULT 7 .pdr
7: 00000000 0 SECTION LOCAL DEFAULT 9 .gnu.attributes
8: 00002000 16 FUNC GLOBAL DEFAULT 1 foo
9: 00004008 0 FUNC LOCAL DEFAULT 1 abar
10: 00002008 0 FUNC LOCAL DEFAULT 1 afoo
11: 00004000 16 FUNC GLOBAL DEFAULT 1 bar
and a corresponding traditional object:
Symbol table '.symtab' contains 12 entries:
Num: Value Size Type Bind Vis Ndx Name
0: 00000000 0 NOTYPE LOCAL DEFAULT UND
1: 00000000 0 SECTION LOCAL DEFAULT 1
2: 00000000 0 SECTION LOCAL DEFAULT 3
3: 00000000 0 SECTION LOCAL DEFAULT 4
4: 00004008 0 FUNC LOCAL DEFAULT 1 abar
5: 00002008 0 FUNC LOCAL DEFAULT 1 afoo
6: 00000000 0 SECTION LOCAL DEFAULT 5
7: 00000000 0 SECTION LOCAL DEFAULT 6

10: 00002000 16 FUNC GLOBAL DEFAULT 1 foo
11: 00004000 16 FUNC GLOBAL DEFAULT 1 bar
respectively. Consequently the right way to retrieve a section symbol's
name has to be chosen in `mips_elf_calculate_relocation' for the purpose
of error reporting.
Originally we produced symbol tables in the traditional object format
only and we handled it correctly until it was lost in a rewrite with:
commit 7403cb6305f5660fccc8869d3333a731102ae978
Author: Mark Mitchell <mark@codesourcery.com>
Date: Wed Jun 30 20:13:43 1999 +0000
probably because of the extra pointer indirection added which made the
same expression have a different meaning.
With the addition of IRIX symbol table format with:
commit 174fd7f9556183397625dbfa99ef68ecd325c74b
Author: Richard Sandiford <rdsandiford@googlemail.com>
Date: Mon Feb 9 08:04:00 2004 +0000
the bug has been partially covered and now when a relocation error is
triggered with an IRIX object the offending section symbol is correctly
reported:
tmpdir/dump0.o: In function `foo':
(.text+0x2000): relocation truncated to fit: R_MIPS_26 against `.text'
tmpdir/dump0.o: In function `bar':
(.text+0x4000): relocation truncated to fit: R_MIPS_26 against `.text'
because `bfd_elf_string_from_elf_section' retrieves the name from the
string table section. With a traditional object however the function
returns an empty string and consequently `no symbol' is printed instead:
tmpdir/dump0.o: In function `foo':
(.text+0x2000): relocation truncated to fit: R_MIPS_26 against `no symbol'
tmpdir/dump0.o: In function `bar':
(.text+0x4000): relocation truncated to fit: R_MIPS_26 against `no symbol'
Restore the original semantics so that the section name is always
correctly retrieved.

Skip attach-many-short-lived-threads.exp on known-broken DejaGnu versions
If the testsuite is run with a DejaGnu version that predates the fix
from last year:
[PATCH] DejaGnu kills the wrong process due to PID-reuse races
http://lists.gnu.org/archive/html/dejagnu/2015-07/msg00005.html
... gdb.threads/attach-many-short-lived-threads.exp fails randomly,
often. Other tests randomly fail due to that issue too, but this one
is _much_ more exposed.
DejaGnu 1.6 was released meanwhile, which includes that DejaGnu fix,
and also some distros backported the fix too.
So skip the test when run with older/broken DejaGnus.

Replace CpuAMD64/CpuIntel64 with AMD64/Intel64
AMD64 vs CpuIntel64 ISA should be handled similar as AT&T vs Intel
syntax. Since cpu_flags isn't sorted by position, we need to check

gdb: Forward VALUE_LVAL when avoiding side effects for STRUCTOP_STRUCT
When evaluating an expression with EVAL_AVOID_SIDE_EFFECTS if the value
we return is forced to be of type not_lval then GDB will be unable to
take the address of the returned value.
Instead, we should properly initialise the LVAL of the returned value.
This commit builds on two previous commits 2520f728b710 (Forward
VALUE_LVAL when avoiding side effects for STRUCTOP_STRUCT) and
ac775bf4d35b (gdb: Forward VALUE_LVAL when avoiding side effects for
STRUCTOP_PTR), which in turn build on ac1ca910d74d (Fixes for PR
exp/15364).
This commit is currently untested due to my lack of access to an OpenCL
compiler, however, if follows the same pattern as the first two commits
mentioned above and so I believe that it is correct.
gdb/ChangeLog:
* opencl-lang.c (evaluate_subexp_opencl): If
EVAL_AVOID_SIDE_EFFECTS mode, forward the VALUE_LVAL attribute to
the returned value in the STRUCTOP_STRUCT case.

gdb: Forward VALUE_LVAL when avoiding side effects for STRUCTOP_PTR
Assume that we have a C program like this:
struct foo_type
{
int var;
} foo;
struct foo_type *foo_ptr = &foo;
int
main ()
{
return foo_ptr->var;
}
Then GDB should be able to evaluate the following, however, it currently
does not:
(gdb) start
...
(gdb) whatis &(foo_ptr->var)
Attempt to take address of value not located in memory.
The problem is that in EVAL_AVOID_SIDE_EFFECTS mode,
eval.c:evaluate_subexp_standard always returns a not_lval value as the
result for a STRUCTOP_PTR operation. As a consequence, the rest of
the code believes that one cannot take the address of the returned
value.
This patch fixes STRUCTOP_PTR handling so that the VALUE_LVAL
attribute for the returned value is properly initialized. After this
change, the above session becomes:
(gdb) start
...
(gdb) whatis &(foo_ptr->var)
type = int *
This commit is largely the same as commit 2520f728b710 (Forward
VALUE_LVAL when avoiding side effects for STRUCTOP_STRUCT) but applied
to STRUCTOP_PTR rather than STRUCTOP_STRUCT. Both of these commits are
building on top of commit ac1ca910d74d (Fixes for PR exp/15364).
gdb/ChangeLog:
* eval.c (evaluate_subexp_standard): If EVAL_AVOID_SIDE_EFFECTS
mode, forward the VALUE_LVAL attribute to the returned value in
the STRUCTOP_PTR case.
gdb/testsuite/ChangeLog:
* gdb.base/whatis.c: Extend the test case.
* gdb.base/whatis.exp: Add additional tests.

MIPS/BFD: Report `bfd_reloc_outofrange' errors as such
A `bfd_reloc_outofrange' condition from `mips_elf_calculate_relocation'
currently triggers the warning callback, which in the case of LD prints
messages like:
foo.o: In function `foo':
(.text+0x0): warning: JALX to a non-word-aligned address
or:
foo.o: In function `foo':
(.text+0x0): warning: PC-relative load from unaligned address
and nothing else, which suggests this is a benign condition and link has
otherwise successfully run to completion. This is however not the case,
the link terminates right away with no further messages and no output
produced.
Use the general error or warning info callback then, preserving the
message format. Also set a BFD error condition so that a failure is
unambiguously reported. Complement the change with a set of suitable
test suite additions.

Enable 64-bit archives in ar and ranlib
Since existing ld and gold support the 64-bit (MIPS) ELF archives, we
can use the 64-bit (MIPS) ELF archives as 64-bit archives. Since the
plugin target is used to create archive in plugin-enabled ar, we need
a way to enable 64-bit archives in the plugin target. This patch adds
--enable-64-bit-archive to bfd to force 64-bit archives in ar and
ranlib. Since both 64-bit MIPS and s390 ELF targets currently use
64-bit archives, 64-bit archives are enabled by default for them.
64-bit archive is generated automatically if the archive is too big.
Tested on Linux/x86 and Linux/x86-64 with existing ld and gold.

Skip an archive element if not added by linker
During archive rescan to resolve symbol references for files added by
LTO, linker add_archive_element callback is called to check if an
archive element should added. After all IR symbols have been claimed,
linker won't claim new IR symbols and shouldn't add the LTO archive
element. This patch updates linker add_archive_element callback to
return FALSE when seeing an LTO archive element during rescan and
changes ELF linker to skip such archive element.

Fix PR python/17386 - add __index__ method to gdb.Value
This patch fixes PR python/17386.
The bug is that gdb.Value does not implement the Python __index__
method. This method is needed to convert a Python object to an index
and is used by various operations in Python, such as indexing an
array.
The fix is to implement the nb_index method for gdb.Value.
nb_index was added in Python 2.5. I don't have a good way to test
Python 2.4, but I made an attempt to accomodate it.
I chose to use valpy_long in all cases because this simplifies porting
to Python 3, and because there didn't seem to be any harm.

Python 2's PyNumberMethods has nb_inplace_divide, but Python 3 does
not. This patch adds it for Python 2.
This buglet didn't cause much fallout because the only non-NULL entry
in value_object_as_number after this is for valpy_divide; and the
missing slot caused it to slide up to nb_floor_divide (where
nb_true_divide was intended).

Fix PR gdb/19828: gdb -p <process from a container>: internal error
When GDB attaches to a process, it looks at the /proc/PID/task/ dir
for all clone threads of that process, and attaches to each of them.
Usually, if there is more than one clone thread, it means the program
is multi threaded and linked with pthreads. Thus when GDB soon after
attaching finds and loads a libthread_db matching the process, it'll
add a thread to the thread list for each of the initially found
lower-level LWPs.
If, however, GDB fails to find/load a matching libthread_db, nothing
is adding the LWPs to the thread list. And because of that, "detach"
hits an internal error:

Working on the fix for gdb/19828, I saw
gdb.threads/attach-many-short-lived-threads.exp fail once in an

issue similar to what's been fixed in remote.c a while ago --
linux-nat.c was not fetching the pending status from the right place.

[Linux] Optimize PID -> struct lwp_info lookup
Hacking the gdb.threads/attach-many-short-lived-threads.exp test to
spawn thousands of threads instead of dozens, and running gdb under
perf, I saw that GDB was spending most of the time in find_lwp_pid:
- captured_main
- 93.61% catch_command_errors
- 87.41% attach_command
- 87.40% linux_nat_attach
- 87.40% linux_proc_attach_tgid_threads
- 82.38% attach_proc_task_lwp_callback
- 81.01% find_lwp_pid
5.30% ptid_get_lwp
+ 0.10% ptid_lwp_p
+ 0.64% add_thread
+ 0.26% set_running
+ 0.24% set_executing
0.12% ptid_get_lwp
+ 0.01% ptrace
+ 0.01% add_lwp
attach_proc_task_lwp_callback is called once for each LWP that we
attach to, found by listing the /proc/PID/task/ directory. In turn,
attach_proc_task_lwp_callback calls find_lwp_pid to check whether the
LWP we're about to try to attach to is already known. Since
find_lwp_pid does a linear walk over the whole LWP list, this becomes
quadratic. We do the /proc/PID/task/ listing until we get two
iterations in a row where we found no new threads. So the second and
following times we walk the /proc/PID/task/ dir, we're going to take
an even worse find_lwp_pid hit.
Fix this by adding a hash table keyed by LWP PID, for fast lookup.
The linked list embedded in the LWP structure itself is kept, and made
a double-linked list, so that removals from that list are O(1). An
earlier version of this patch got rid of this list altogether, but
that revealed hidden dependencies / assumptions on how the list is
sorted. For example, killing a process and then waiting for all the
LWPs status using iterate_over_lwps only works as is because the
leader LWP is always last in the list. So I thought it better to take
an incremental approach and make this patch concern itself _only_ with
the PID lookup optimization.

[Linux] Avoid refetching core-of-thread if thread hasn't run
Hacking the gdb.threads/attach-many-short-lived-threads.exp test to
spawn thousands of threads instead of dozens, I saw GDB having trouble
keeping up with threads being spawned too fast, when it tried to stop
them all. This was because while gdb is doing that, it updates the
thread list to make sure no new thread has sneaked in that might need
to be paused. It does this a few times until it sees no-new-threads
twice in a row. The thread listing update itself is not that
expensive, however, in the Linux backend, updating the threads list
calls linux_common_core_of_thread for each LWP to record on which core
each LWP was last seen running, which opens/reads/closes a /proc file
for each LWP which becomes expensive when you need to do it for
thousands of LWPs.
perf shows gdb in linux_common_core_of_thread 44% of the time, in the
stop_all_threads -> update_thread_list path in this use case.
This patch simply makes linux_common_core_of_thread avoid updating the
core the thread is bound to if the thread hasn't run since the last
time we updated that info. This makes linux_common_core_of_thread
disappear into the noise in the perf report.

[Linux] Read vDSO range from /proc/PID/task/PID/maps instead of /proc/PID/maps
... as it's _much_ faster.
Hacking the gdb.threads/attach-many-short-lived-threads.exp test to
spawn thousands of threads instead of dozens to stress and debug
timeout problems with gdb.threads/attach-many-short-lived-threads.exp,
I saw that GDB would spend several seconds just reading the
/proc/PID/smaps file, to determine the vDSO mapping range. GDB opens
and reads the whole file just once, and caches the result, but even
that is too slow. For example, with almost 8000 threads:
$ ls /proc/3518/task/ | wc -l
7906
reading the /proc/PID/smaps file grepping for "vdso" takes over 15
seconds :
$ time cat /proc/3518/smaps | grep vdso
7ffdbafee000-7ffdbaff0000 r-xp 00000000 00:00 0 [vdso]
real 0m15.371s
user 0m0.008s
sys 0m15.017s
Looking around the web for hints, I found a nice description of the
issue here:
http://backtrace.io/blog/blog/2014/11/12/large-thread-counts-and-slow-process-maps/
The problem is that /proc/PID/smaps wants to show the mappings as
being thread stack, and that has the kernel iterating over all threads
in the thread group, for each mapping.
The fix is to use the "map" file under /proc/PID/task/PID/ instead of
the /proc/PID/ one, as the former doesn't mark thread stacks for all
threads.
That alone drops the timing to the millisecond range on my machine:
$ time cat /proc/3518/task/3518/smaps | grep vdso
7ffdbafee000-7ffdbaff0000 r-xp 00000000 00:00 0 [vdso]
real 0m0.150s
user 0m0.009s
sys 0m0.084s
And since we only need the vdso mapping's address range, we can use
"maps" file instead of "smaps", and it's even cheaper:
/proc/PID/task/PID/maps :
$ time cat /proc/3518/task/3518/maps | grep vdso
7ffdbafee000-7ffdbaff0000 r-xp 00000000 00:00 0 [vdso]

Linux native thread create/exit events support
A following patch (fix for gdb/19828) makes linux-nat.c add threads to
GDB's thread list earlier in the "attach" sequence, and that causes a
surprising regression on
gdb.threads/attach-many-short-lived-threads.exp on my machine. The
extra "thread x exited" handling and traffic slows down that test
enough that GDB core has trouble keeping up with new threads that are
spawned while trying to stop existing ones.
I saw the exact same issue with remote/gdbserver a while ago and fixed
it in 65706a29bac5 (Remote thread create/exit events) so part of the
fix here is the exact same -- add support for thread created events to
gdb/linux-nat.c. infrun.c:stop_all_threads enables those events when
it tries to stop threads, which ensures that new threads never get a
chance to themselves start new threads, thus fixing the race.

MIPS/GAS: Cut TLS reloc dead code path in `md_apply_fix'
With code refactoring made in commit b886a2ab0d52 and the addition of
`calculate_reloc' and a separate test for TLS relocs against constants
made there the preexisting fall-through from the TLS reloc switch case
has effectively become a dead execution path. This is because the call
to `calculate_reloc' present there is only made if `fixP->fx_done' is
true, which can only be the case if `fixP->fx_addsy' is NULL, which in
turn has already triggered the TLS reloc test and made execution break
out of the switch statement.
Remove the fall-through then and reshape code accordingly.

Fix PR python/19438, PR python/18393 - initialize dictionaries
This fixes PR python/19438 and PR python/18393. Both bugs are about
invoking dir() on some Python object implemented by gdb, and getting a
crash.
The crash happens because the dictionary field of these objects was
not initialized. Apparently what happens is that this field can be
lazily initialized by Python when assigning to an attribute; and it
can also be handled ok when using dir() but without __dict__ defined;
but gdb defines __dict__ because this isn't supplied automatically by
Python.
The docs on this seem rather sparse, but this patch works ok.
An alternative might be to lazily create the dictionary in
gdb_py_generic_dict, but I went with this approach because it seemed
more straightforward.

MIPS: Fix the encoding of immediates with microMIPS JALX
The microMIPS JALX instruction shares the R_MICROMIPS_26_S1 relocation
with microMIPS J/JAL/JALS instructions, however unlike the latters its
encoded immediate argument is unusually shifted left by 2 rather than 1
in calculating the value used for the operation requested.
We already handle this exception in `mips_elf_calculate_relocation' in
LD, in a scenario where JALX is produced as a result of relaxing JAL for
the purpose of making a cross-mode jump. We also get it right in the
disassembler in `decode_micromips_operand'.
What we don't correctly do however is processing microMIPS JALX produced
by GAS from an assembly source, where a non-zero constant argument or a
symbol reference with a non-zero in-place addend has been used. In this
case the same calculation is made as for microMIPS J/JAL/JALS, causing
the wrong encoding to be produced by GAS on making an object file, and
then again by LD in the final link. The latter in particular causes the
calculation, where the addend fits in the relocatable field, to produce
different final addresses for the same source code depending on whether
REL or RELA relocations are used.
Correct these issues by special-casing microMIPS JALX in the places that
have been previously missed.

Remove unsupported `am34-*-linux*' target triplet
The `am34-*-linux*' target cannot be configured for, `am34' is not a CPU
name recognized by `config.sub'. It has never been, required code has
not been contributed to GNU config, neither before nor since the
addition of the target triplet to our configury with commit bfff16424942
("Add MN10300 linker relaxation support for symbol differences") back in
2007. Also there is no difference in actual tool configuration between
the `am34-*-linux*' and `am33_2.0-*-linux*' targets, except from a
different executable prefix and tooldir name.

gas/arc: Make member of arc_flags const
By making the flgp field of struct arc_flags constant we can remove a

gas/arc: Fix array overrun when checking opcode array
The opcode array iterator mechanism can, in some situations, result in
reading memory outside of the opcode array. When using the
iterator-next mechanism to find the next possible arc_opcode, if we find
an opcode where the name field is NULL, or the name does not match, then
the cached opcode pointer is not set to NULL. The result is that
another call to iterator-next will again increment the opcode
pointer (which might now point outside the opcode array) and attempt to
access the name field of this undefined opcode.
Fixed in this commit by clearing the cached opcode pointer.
I've added a test case, which currently shows the bug, however, this
will only expose this bug while the opcode used (dsp_fp_cmp) is the last
opcode in the table.

Add mi-threads-interrupt.exp test (PR 20039)
Add a new test for PR 20039. The test spawns new threads, then tries to
interrupt, continue, and interrupt again. This use case was fixed by
commit 5fe966540d6b748f825774868463003700f0c878 in master, but gdb 7.11
is affected (so if you try it on the gdb-7.11-branch right now, the test
will fail).
New in v2, the test now handles mi-async on mode properly. The failure
was specific to mi-async off, but I don't think it's bad to test the
same thing under async on mode. I added a little hack when running in
async mode to work around bug 20045.
I also removed one continue/interrupt pair, as a single one was enough to
trigger the problem.

Fix double prompt output after run control MI commands with mi-async on (PR 20045)
When you use a run control command (-exec-run, -exec-continue,
-exec-next, ...) with mi-async on, an extra (gdb) prompt is displayed:
-exec-continue
^running
*running,thread-id="all"
(gdb)
(gdb)
It doesn't seem to be a big problem for front-ends, since this behavior
started in gdb 7.9 and we haven't heard anything about that. However,
it caused me some trouble while writing a test for PR 20039 [1].
The problem comes from an extra (gdb) prompt that we write when running
in mi-async off mode to emulate a past buggy behavior. When executing a
run control command synchronously, previous gdbs always printed a prompt
right away, even though they are not ready to accept new MI commands
until the target stops. Only at this time should they display a prompt.
But to keep backwards compatibility apparently, we print it anyway.
Since commit 198297aaf, the condition that decides whether we should
print that "bogus" prompt or not has become true, even when running with
mi-async on. Since we already print a prompt at the end of the
asynchronous command execution, it results in two prompts for one
command.
The proposed fix is to call target_can_async_p instead of
target_is_async_p, to make the condition:
if (!target_can_async_p () || sync_execution)
... show prompt ...
That shows the prompt if we are emulating a synchronous command on top
of an asynchronous target (sync_execution) or if the target simply can't
run asynchronously (!target_can_async_p ()).
Note that this code is changed and this bug fixed by Pedro's separate
console series, but I think it would be nice to have it fixed in the
mean time.
I ran the gdb.mi directory of the testsuite with mi-async on and off, I
didn't see any regressions.
gdb/ChangeLog:
* mi/mi-main.c (mi_on_resume): Call target_can_async_p instead
of target_is_async_p.

MIPS/opcodes: Correct mixed MIPS16 and microMIPS disassembly
Mixing MIPS16 and microMIPS code in a single binary isn't usually
supported but GAS happily produces such code if requested. However it
is not correctly disassembled even if a symbol table is available and
function symbols are correctly anotated with the ISA mode. This is
because the ELF-header global microMIPS ASE flag takes precedence over
MIPS16 function annotation, causing them to be treated as regular MIPS
code.
Correct the problem by respecting function symbol anotation regardless
of the ELF-header flag.

Fix -exec-run not running asynchronously with mi-async on (PR gdb/18077)
When doing -exec-run on a freshly started GDB, the only target on the
target stack at the time the dummy one. When mi_async_p is called to
know whether the run should be async, it queries whether the current
target (dummy) supports async, and the answer is no. The fix is to make
the code query the target that will be used for the run, which is not
necessarily the current target.
No regressions in the gdb.mi directory using the unix, native-gdbserver
and native-extended-gdbserver boards. The test doesn't pass when
forcing maint set target-async off, obviously, since it makes mi-async
have no effect. It doesn't seem like other tests are checking for that
eventuality, so I didn't in the new test.

Add self-test framework to gdb
I wanted to unit test the Rust lexer, so I added a simple unit testing
command to gdb.
The intent is that self tests will only be compiled into gdb in
development mode. In release mode they simply won't exist. So, this
exposes $development to C code as GDB_SELF_TEST.
In development mode, test functions are registered with the self test
module. A test function is just a function that does some checks, and
throws an exception on failure.
Then this adds a new "maint selftest" command which invokes the test

Match shell_prompt # in batch-preserve-term-settings.exp
batch-preserve-term-settings.exp fails if the shell prompt isn't $. It
is # in our testing env. In fact, the shell prompt can be anything.
The perfect solution would be "set_board_info shell_prompt" in the
host board file, and use board_info shell_prompt in
batch-preserve-term-settings.exp. This is a little bit overkill to
me, and we still need to figure out the different prompts on different
shells. I also tried to start shell with the prompt preset, but there is
not unique way to set shell prompt in different shells, so I give up.
It is reasonably simple to match either $ or # for the shell prompt, and
we can easily extend it to match other char, like >.

V850/BFD: Call `_bfd_elf_copy_private_bfd_data' again
Correct a regression introduced with commit 685080f21003 ("Adds support
for generating notes in V850 binaries.") which replaced rather than
extending the call to `_bfd_elf_copy_private_bfd_data' with

Strip global symbol defined in discarded section
When a global symbol is defined in COMDAT group, we shouldn't leave an

LD/testsuite: Add STB_GNU_UNIQUE cross-linker test
Some targets are only really, or at least regularly, regression-tested
in a crossed configuration. Currently we only have native compiled test
cases for the STB_GNU_UNIQUE feature in the linker test suite. This is
nice, covering run-time semantics even, but quite often not run at all.
Consequently a regression may remain unnoticed for long.
Add a simple test case then to provide basic linker coverage with no
need for a compiler or a native toolchain.

Throw NOT_AVAILABLE_ERROR in read_stack and read_code
Nowadays, read_memory may throw NOT_AVAILABLE_ERROR (it is done by
patch http://sourceware.org/ml/gdb-patches/2013-08/msg00625.html)
however, read_stack and read_code still throws MEMORY_ERROR only. This
causes PR 19947, that is prologue unwinder is unable unwind because
code memory isn't available, but MEMORY_ERROR is thrown, while unwinder
catches NOT_AVAILABLE_ERROR.

The fix is to let read_stack and read_code throw NOT_AVAILABLE_ERROR too,
in order to align with read_memory.

Fix solib-display.exp remote check
This test currently uses [is_remote target] to check if the test is
supported. This is not quite correct, as the limitation is actually
that it requires support for "running", ruling out stub-like targets.
Therefore, it should check for use_gdb_stub.
This has no visible effect right now, but it will once we make the
native-gdbserver board non-dejagnu-remote.

* gdb.base/solib-display.exp: Check for [use_gdb_stub]Â instead

Introduce procedure use_gdb_stub
This patch introduces the use_gdb_stub procedure, which allows getting
the right value of the use_gdb_stub variable/property in any all
situations.
When calling it before the $use_gdb_stub global variable has been set,
it will return the value of the use_gdb_stub property from the board
file. This happens when tests want to bail out early (even before gdb
has been started) when the current test setup is a stub.
Otherwise, it returns the value of the $use_gdb_stub global.
It's possible for these two to differ when a test file overrides the
value of the global.

* lib/gdb.exp (use_gdb_stub): New procedure.

oldloc = setlocale (LC_ALL, NULL);
setlocale (LC_ALL, "");
...
setlocale (LC_ALL, oldloc);
I.e., the second setlocale call frees 'oldloc'.
From http://pubs.opengroup.org/onlinepubs/9699919799/functions/setlocale.html :
"The returned string pointer might be invalidated or the string
content might be overwritten by a subsequent call to setlocale()."

[AArch64] Also puts value in place for R_AARCH64_RELATIVE
When handling absolute relocations for global symbols bind within the
shared object, AArch64 will generate one dynamic RELATIVE relocation,
but won't apply the value for this absolution relocations at static
linking stage. This is different from AArch64 gold linker and x86-64.
This is not a bug as AArch64 is RELA, there is only guarantee that
relocation addend is placed in the relocation entry. But some
system softwares originally writen for x86-64 might assume AArch64
bfd linker gets the same behavior as x86-64, then they could take
advantage of this buy skipping those RELATIVE dynamic relocations
if the load address is the same as the static linking address.
This patch makes AArch64 BFD linker applies absolution relocations at
static linking stage for scenario described above. Meanwhile old AArch64
android loader has a bug (PR19163) which relies on current linker behavior
as a workaround, so the same option --no-apply-dynamic-relocs added.

Fix PR gdb/16818, workaround Python's forcing of -export-dynamic
GDB's use of --dynamic-list to only export the proc-service symbols is
broken due to Python's "python-config --ldflags" saying we should link
with -export-dynamic, causing us to export _all_ extern symbols
anyway. On Fedora 23:
$ python-config --ldflags
-lpython2.7 -lpthread -ldl -lutil -lm -Xlinker -export-dynamic
$ python3.4-config --ldflags
-L/usr/lib64 -lpython3.4m -lpthread -ldl -lutil -lm -Xlinker -export-dynamic
Having GDB export all its symbols leads to issues such as PR gdb/16818
(GDB crashes when using name for target remote hostname:port), where a
GDB symbol unintentionally preempts a symbol in one of the NSS modules
glibc loads into the process. NSS modules should not define symbols
outside the implementation namespace or the relevant standards, but,
alas, that's a longstanding and hard to fix issue. See libc-alpha
discussion at:
[symbol name space issues with NSS modules]
https://sourceware.org/ml/libc-alpha/2016-04/msg00130.html
Python should instead be either using GCC's symbol visibility feature
or -Wl,--dynamic-list as well, to only export Python API symbols, but,
it doesn't. There are bugs open upstream for that:
[Use -Wl,--dynamic-list=x.list, not -Xlinker -export-dynamic]
http://bugs.python.org/issue10112
[Use GCC visibility attrs in PyAPI_*]
http://bugs.python.org/issue11410
But that's taking a long while to resolve.
I thought of working around this Python issue by making GDB build with
-fvisibility=hidden, as Jan suggests in Python issue 10112, as then
Python's "-Xlinker -export-dynamic" has no effect. However, that
would need to be done in the whole source tree (bfd, libiberty, etc.),
and I think that would break GCC plugins, as I believe those have
access to all of GCCs symbols, by "design". So we'd need a new
configure switch, or have the libraries in the tree detect which of
GCC or GDB is being built, but that doesn't work, because the answer
can be "both" with combined builds...
So this patch instead works around Python's bug, by simply sed'ing
away "-Xlinker -export-dynamic" from the result of python-config.py
--ldflags, making -Wl,--dynamic-list work again as it used to. It's
ugly, but so is the bug...
Note that if -Wl,--dynamic-list doesn't work, we always link with
-rdynamic, so static Python should still work.
Tested on F23 with --python=python (Python 2.7) and
--python=python3.4.

Fix detach.exp remote check
This test seems to work with both native-gdbserver and
native-extended-gdbserver, so I removed the remote check.
When running with native-gdbserver (a stub-like target), detach makes
gdbserver stop and gdb disconnect. runto_main just spawns a brand new
gdbserver. So it tests the exact same thing twice. It doesn't hurt
though.
With native-extended-gdbserver, the test is probably a bit more useful
(and similar to native). It tests running/detaching twice using the
same gdb/gdbserver instances, since with extended-remote, you can
detach/attach/run all you want, unlike with remote.
gdb/testsuite/ChangeLog:
* gdb.base/detach.exp: Remove is_remote check.

Fix annota-input-while-running.exp remote check
The comment says that we can't use runto_main here becore it doesn't
know how to handle annotation. Instead, the test puts a breakpoint at
main and calls run by hand. Therefore, it can't work with stub targets,
since they can't "run". The check should be then changed to check the
use_gdb_stub variable instead of [is_remote target].
But as an alternative, we can just use runto_main and enable annotations
after, since the "run to main" part is not really part of what we want
to test.
I also removed the "set test..." line that is unused.
gdb/testsuite/ChangeLog:
* gdb.base/annota-input-while-running.exp: Don't check for
[is_remote target]. Enable annotations after running to main.

Fix write endianness/size problem for fast tracepoint enabled flag
I am sending this fix on behalf of Par Olsson, as a follow-up of this
one:
https://www.sourceware.org/ml/gdb-patches/2015-10/msg00196.html
This problem is exposed when enabling/disabling fast tracepoints on big
endian machines. The flag is defined as an int8_t, but is written from
gdbserver as an integer (usually 32 bits). When the agent code reads it
as an int8_t, it only considers the most significant byte, which is
always 0.
Also, we were writing 32 bits in an 8 bits field, so the write would
overflow, but since the following bytes are padding (the next field is
an uint64_t), it luckily didn't cause any issue on little endian
systems.
The fix was originally tested on ARM big endian systems, but I don't
have access to such a system. However, thanks to Marcin's PowerPC fast
tracepoint patches and gcc110 (big endian Power7) on the gcc compile
farm, I was able to reproduce the problem, test the fix and write a
test (the following patch).

ftrace tests: Use gdb_load_shlib result to lookup IPA in info sharedlibrary
Some fast tracepoints tests make sure that the in-process agent library
is properly loaded, by searching for the library name in "info
sharedlibrary".
Originally, it would search for the full path. Since patch "Make ftrace
tests work with remote targets" [1], the "runtime" location of the IPA,
in the standard output directory, is not the same as the original
location, in the gdbserver build directory. Therefore, the patch
changed the checks:
gdb_test "info sharedlibrary" ".*${libipa}.*" "IPA loaded"
to
gdb_test "info sharedlibrary" ".*[file tail ${libipa}].*" "IPA loaded"
so that only the "libinproctrace.so" part would be searched for.
Antoine (in CC) pointed out that I missed some, so I have to update
them. In the mean time, I noticed that I missed a few test failures:
adding the SONAME to the IPA makes it possible for the test executable
to erroneously pick up libinproctrace.so from /usr/lib if the test
harness failed to put the libinproctrace.so we want to test in the right
place. To mitigate that kind of error in the future, we can use the
return value of gdb_load_shlib (the path of the "runtime" version of the
library) and use that to search in the output of info sharedlibrary.
When testing locally, gdb_load_shlib returns the full normalized path of
the destination library, which the test executable should use e.g.:
/path/to/gdb/testsuite/outputs/gdb.trace/thetest/libinproctrace.so
My testing showed that it was the same path that gdb displayed in info
sharedlibrary. If the test executable picks up another
libinproctrace.so, the test will fail.
When testing remotely, gdb_load_shlib/gdb_remote_download only returns
us "libinproctrace.so", so the situation doesn't really change. If
there is a rogue libinproctrace.so in /usr/lib on the target and we fail
to download ours, it might cover up a test failure. But that situation
is probably still better than the original one, where it wasn't possible
to test remotely using the IPA at all.

Remove need_step_over from struct lwp_info
Hi,
I happen to see that field need_step_over in struct lwp_info is only
used to print a debug info. need_step_over is set in linux_wait_1
when breakpoint_here is true, however, we check breakpoint_here too in
need_step_over_p and do the step over. I think we don't need field
need_step_over, and check breakpoint_here directly in need_step_over_p.
This field was added in this patch

wasn't changed much since then.
This patch is to remove it.

Make gdb_load_shlibs return the destination path of the library
This patch makes gdb_load_shlibs return the destination path of the
copied library. To make the procedure implementation and interface more
straightforward, it also changes it so that it accepts a single shared
library path at the time. Therefore, calls that are passed multiple
libraries:
gdb_load_shlibs $lib1 $lib2
must be changed to separate calls:
gdb_load_shlibs $lib1
gdb_load_shlibs $lib2
A subtle impact is the solib-search-path handling. In the former
version, solib-search-path is set using the directory of the first
passed lib (further calls overwrite the value). In the later version,
the directory of the library passed to the last call to gdb_load_shlibs
remnains. I don't think that's a problem in practice, since if we had
tests that needed multiple different paths in solib-search-path, they
wouldn't work in the first place.
Changed in v2:
* Split behavioural and rename changes in two separate patches.
gdb/testsuite/ChangeLog:
* lib/gdb.exp (gdb_load_shlibs): Accept a single argument. Return
result of gdb_remote_download.

Workaround gdbserver<7.7 for setfs
With current FSF GDB HEAD and old FSF gdbserver I expected I could do:
gdb -ex 'file target:/root/redhat/threadit' -ex 'target remote :1234'
(supplying that unsupported qXfer:exec-file:read by "file")
But that does not work because:
Sending packet: $vFile:setfs:0#bf...Packet received: OK
Packet vFile:setfs (hostio-setfs) is supported
...
Sending packet: $vFile:setfs:104#24...Packet received: OK
"target:/root/redhat/threadit": could not open as an executable file: Invalid argument
GDB documentation says:
The valid responses to Host I/O packets are:
An empty response indicates that this operation is not recognized.
This "empty response" vs. "OK" was a bug in gdbserver < 7.7. It was fixed by:

c_value_print: Revert 'val' to a reference for TYPE_CODE_STRUCT
Currently c_value_print will turn struct reference values into pointers before
doing a set of RTTI checks. This was introduced as a fix to PR c++/15401.
If there's RTTI the pointer will be adjusted and converted back to a reference.
However, if there's no RTTI the value will still be treated as a pointer during
the remainder of the function.
This patch moves the conversion down so that it's always performed when needed.
Notice this currently has not user-visible effects, so can be seen as a small
code cleanup. However, it'll be necessary for the bug-fix for handling
synthetic C++ references. It causes no testsuite regressions.

Avoid non-C++-enabled babeltrace versions
In some babeltrace versions before 1.2.0, the header file iterator.h
declares the enum values `BT_SEEK_*' within the struct declaration of
bt_iter_pos. The enum values are supposed to be globally-scoped, which
works for C, but not for C++. Later babeltrace versions declare the
enum outside the struct:
https://lists.lttng.org/pipermail/lttng-dev/2013-September/021411.html
Now that GDB is compiled with C++, the GDB build fails on a system with
an affected babeltrace version: the compiler complains about a missing
declaration of BT_SEEK_BEGIN in ctf.c.
This patch enhances the configure check to recognize such babeltrace
versions as unusable for GDB.
gdb/ChangeLog:
* configure.ac: Enhance configure check for babeltrace to reject
non-C++-enabled versions.
* configure: Regenerate.

add casts to avoid arithmetic on void *
arithmetic on void * is undefined in ISO C, so we should avoid it. In
GNU C sizeof void * is defined as 1, and that is pretty clearly what
this code wants, so change it to do arithmetic on bfd_byte *.
Unfortunately most of the argument types come from virtual function
interfaces so changing the types to bfd_byte * isn't trivial though it
might make the code clearer. So for the moment its easiest to leave the
variable types as void * and cast before doing arithmetic.

fort_dyn_array: Use value constructor instead of raw-buffer manipulation.
Instead of pre-computing indices into a fortran array re-use
the value_* interfaces to subscript a fortran array.
The benefit of using the new interface is that it takes care of
dynamic types and resolve them when needed.
This fixes issues when printing structures with dynamic arrays from toplevel.

Resume the inferior with signal rather than stepping over
When GDBserver steps over a breakpoint using software single step, it
enqueues the signal, single step and deliver the signal in the next
resume if step over is not needed. In this way, the program won't
receive the signal if the conditional breakpoint is set a branch to
self instruction, because the step over is always needed.

[GDBserver] Don't error in reinsert_raw_breakpoint if bp->inserted
GDBserver steps over a breakpoint while the single step breakpoint
is inserted at the same address, there are two breakpoint objects
using single raw breakpoint, which is inserted (for single step).
When step over is finished, GDBserver reinsert the breakpoint, but
it finds the raw breakpoint is already inserted, and error out
"Breakpoint already inserted at reinsert time." Even if I change the
order to delete reinsert breakpoints first (which only decreases the
refcount, but leave inserted flag unchanged), the error is still
there.
The fix is to remove the error and return instead.

Insert breakpoint even when the raw breakpoint is found
When GDBserver inserts a breakpoint, it looks for raw breakpoint, if
the raw breakpoint is found, increase its refcount, and return. This
doesn't work when it steps over a breakpoint using software single
step and the underneath instruction of breakpoint is branch to self.
When stepping over a breakpoint on ADDR using software single step,
GDBserver uninsert the breakpoint, so the corresponding raw breakpoint
RAW's 'inserted' flag is zero. Then, GDBserver insert single step
breakpoint at the same address ADDR because the instruction is branch
to self, the same raw brekapoint RAW is found, and increase the
refcount. However, the raw breakpoint is not inserted, and the
program won't stop.

only skip the non-single-step breakpoints if they are inserted at
the place we are stepping over, however we don't want to skip
single-step breakpoint if its thread is the thread we are stepping

Before this patch

read_value_memory checks parameter 'stack', and call read_stack or

Centralize yacc interface names remapping (yyparse, yylex, yyerror, etc)
This factors out all the yy-variables remapping to a single file,
instead of each parser having to do the same, with different prefixes.
With this, a parser just needs to define the prefix they want and
include yy-remap.h, which does the dirty job.
Note this renames the c_error, ada_error, etc. functions. Writing the
remapping pattern as:
#define yyerror GDB_YY_REMAP (error)
instead of:
#define yyerror GDB_YY_REMAP (yyerror)
would have avoided the renaming. However, that would be problematic
if we have a macro 'foo' in scope, when we write:
#define yyfoo GDB_YY_REMAP (foo)
as that would expand 'foo'.
The c_yyerror etc. naming end ups indicating that this is a yacc
related function more clearly, so feels like a good change, anyway.

Propagate GDB/C++ exceptions across readline using sj/lj-based TRY/CATCH
If we map GDB'S TRY/CATCH macros to C++ try/catch, GDB breaks on
systems where readline isn't built with exceptions support. The
problem is that readline calls into GDB through the callback
interface, and if GDB's callback throws a C++ exception/error, the
system unwinder won't manage to unwind past the readline frame, and
ends up calling std::terminate(), which aborts the process:
(gdb) whatever-command-that-causes-an-error
terminate called after throwing an instance of 'gdb_exception_RETURN_MASK_ERROR'
Aborted
$
This went unnoticed for so long because:
- the x86-64 ABI requires -fasynchronous-unwind-tables, making it
possible for exceptions to cross readline with no special handling.
But e.g., on ARM or AIX, unless you build readline with
-fexceptions, you trip on the problem.
- TRY/CATCH was mapped to setjmp/longjmp, even in C++ mode, until
quite recently.
The fix is to catch and save any GDB exception that is thrown inside
the GDB readline callback, and then once the callback returns back to
the GDB code that called into readline in the first place, rethrow the
saved GDB exception.
This is similar in spirit to how we catch/map GDB exceptions at the
GDB/Python and GDB/Guile API boundaries.
The next question is then: if we intercept all exceptions within GDB's
readline callback, should we simply return normally to readline? The
callback prototype has no way to signal an error back to readline (*).
The answer is no -- if we return normally, we'll be returning to a
loop inside rl_callback_read_char that continues processing pending
input, calling into GDB again, redisplaying the prompt, etc. Thus if
we want to error out of rl_callback_read_char, we need to long jump
across it, just like we always did before TRY/CATCH were ever mapped
to C++ exceptions.
My first approach built a specialized API to handle this, with a
couple macros to hide the setjmp/longjmp and the struct gdb_exception
saving/rethrowing.
However, I realized that we need to:
- Handle multiple active rl_callback_read_char invocations. If,
while processing input something triggers a secondary prompt, we
end up in a nested rl_callback_read_char call, through
gdb_readline_wrapper.
- Propagate a struct gdb_exception along with the longjmp.
... and that this is exactly what the setjmp/longjmp-based TRY/CATCH
does.
So the fix makes the setjmp/longjmp TRY/CATCH always available under
new TRY_SJLJ/CATCH_SJLJ aliases, even when TRY/CATCH is mapped to C++
try/catch, and then uses TRY_SJLJ/CATCH_SJLJ to propagate GDB
exceptions across the readline callback.
This turns out to be a much better looking fix than my bespoke API
attempt, even. We'll probably be able to simplify TRY_SJLJ/CATCH_SJLJ
when we finally get rid of TRY/CATCH all over the tree, but until
then, this reuse seems quite nice for avoiding a second parallel
setjmp/longjmp mechanism.
(*) - maybe we could propose a readline API change, but we still need
to handle current readline, anyway.

[ARM] Clear reserved bits in CPSR
Bits 20 ~ 23 of CPSR are reserved (RAZ, read as zero), but they are not
zero if the arm program runs on aarch64-linux. AArch64 tracer gets PSTATE
from arm 32-bit tracee as CPSR, but bits 20 ~ 23 are used in PSTATE. I
think kernel should clear these bits when it is read through ptrace, but
the fix in user space is still needed.

Hi,
I am seeing the fail below on aarch64-linux with gcc 4.9.2,

(gdb) FAIL: gdb.base/annota1.exp: breakpoint main
the test expects the breakpoint is set on line 15. Let us look at
the main function,
12 int
13 main (void)
14 {
15 int my_array[3] = { 1, 2, 3 }; /* break main */
16
17 value = 7;

the breakpoint is set on the right address after skipping prologue, but
0x00000000004006e8 is mapped to the line 14, as shown below,

3 14 0x00000000004006e8
4 15 0x00000000004006fc
so GDB does nothing wrong. Program hits breakpoint on either line 14
or line 15 is right to me. With anther gcc (4.9.3), the line-table looks
correct, and no test fail. Instead of setting breakpoint on main and
assuming the line is what we get from the source, we can set breakpoint
on that line. On the other hand, the test prints the values of the
array and check, so we need to set breakpoint on the line setting the
values of array and "next", rather than setting the breakpoint on main.

function callee is prologue-less, because nothing needs to be saved
on stack,
(gdb) disassemble callee
Dump of assembler code for function callee:
0x00010680 <+0>: movw r3, #2364 ; 0x93c
0x00010684 <+4>: movt r3, #2
0x00010688 <+8>: ldr r3, [r3]
0x0001068c <+12>: add r2, r3, #1
0x00010690 <+16>: movw r3, #2364 ; 0x93c
0x00010694 <+20>: movt r3, #2
0x00010698 <+24>: str r2, [r3]

0x000106a0 <+32>: mov r0, r3
0x000106a4 <+36>: bx lr
program stops at the 0x106a0 (passed the epilogue) after the first
"step". When second "step" is executed, the stepping range is
[0x10680-0x106a0], which starts from the first instruction of function
callee (because it doesn't have prologue).
infrun: resume (step=1, signal=GDB_SIGNAL_0), trap_expected=0, current thread [LWP 2461] at 0x1069c^M
infrun: prepare_to_wait^M
infrun: target_wait (-1.0.0, status) =^M
infrun: 2461.2461.0 [LWP 2461],^M
infrun: status->kind = stopped, signal = GDB_SIGNAL_TRAP^M
infrun: TARGET_WAITKIND_STOPPED^M
infrun: stop_pc = 0x10698^M
infrun: stepping inside range [0x10680-0x106a0]
When program goes out of the range, it stops at the caller of callee,
and test fails. IOW, if function callee has prologue, the stepping
range won't start from the first instruction of the function, and
program stops at the prologue and test passes.
IMO, GDB does nothing wrong, but test shouldn't expect the program
stops in callee after the second "step". I decide to fix test rather
than GDB. In this patch, I change to test to do one "step", and check
the program is still in callee, then, do multiple "step" until program
goes out of the callee.

Deliver signal in hardware single step
GDBserver doesn't deliver signal when stepping over a breakpoint even
hardware single step is used. When GDBserver started to step over
(thread creation) breakpoint for mutlit-threaded debugging in 2002 [1],
GDBserver behaves this way.
This behavior gets trouble on conditional breakpoints on branch to
self instruction like this,
0x00000000004005b6 <+29>: jmp 0x4005b6 <main+29>
and I set breakpoint
$(gdb) break branch-to-self.c:43 if counter > 3
and the variable counter will be set to 5 in SIGALRM signal handler.
Since GDBserver keeps stepping over breakpoint, the SIGALRM can never
be dequeued and delivered to the inferior, so the program can't stop.
The test can be found in gdb.base/branch-to-self.exp.
GDBserver didn't deliver signal when stepping over a breakpoint because
a tracepoint is collected twice if GDBserver does so in the following
scenario, which can be reproduced by gdb.trace/signal.exp.
- program stops at tracepoint, and tracepoint is collected,
- gdbserver starts a step-over,
- a signal arrives, step-over is canceled, and signal should be passed,
- gdbserver starts a new step-over again, pass the signal as well,
- program stops at the entry of signal handler, step-over finished,
- gdbserver proceeds,
- program returns from the signal handler, again to the tracepoint,
and thus is collected again.
The spurious collection isn't that harmful, IMO, so it should be OK
to let GDBserver deliver signal when stepping over a breakpoint.

This is to test whether GDBserver deliver signal to the inferior while

Set dynobj to a normal input file if possible
When check_relocs is called after gc-sections has run,
_bfd_elf_link_create_dynstrtab may be called with an dynamic object
and hash_table->dynobj may be NULL. We may not set dynobj, an input
file holding linker created dynamic sections to the dynamic object,
which has its own dynamic sections. We need to find a normal input
file to hold linker created sections if possible. Otherwise ld will
crash during LTO input rescan when linker created dynamic section
overrides input dynamic section.

MIPS/GAS: Fix an ISA override not lifting ABI restrictions
Correct a regression introduced with commit 919731affbef ("Add MIPS
.module directive") causing code like:
.set mips3
dli $2, 0x9000000080000000
to fail assembly with the following error message produced:
Error: number (0x9000000080000000) larger than 32 bits
if built with `mips3' selected as the global ISA (e.g. `-march=mips3').
This is because a `.set' directive doing an ISA override does not lift
the ABI restriction on register sizes if the ISA remains unchanged.
Previously the directive always set register sizes from the ISA chosen,
which is what some code expects. Restore the old semantics then.

MIPS: Go back with the default Linux # of registers to 90
Set the number of registers for non-XML-described Linux targets to 90,
reverting a change made here with the addition of DSP register support:

Author: Maciej W. Rozycki <macro@linux-mips.org>

and fixing a regression introduced for legacy `gdbserver' targets
causing a "Remote 'g' packet reply is too long" error message where the
amount of register data received with a `g' packet (90) exceeds the
maximum number of registers expected (79).
Update the setting for XML-described targets, reflecting the actual
number of registers which have been assigned numbers, matching the:
gdb_assert (gdbarch_num_regs (gdbarch) <= MIPS_RESTART_REGNUM);
requirement in `mips_linux_init_abi'.

* mips-tdep.c (mips_gdbarch_init): For GDB_OSABI_LINUX set
`num_regs' to 90 rather than 79. Where a target description is
present adjust the setting appropriately.

Check R_386_NONE/R_X86_64_NONE in eh6.d
There is no need for run-time relocation when converting pointers
in .eh_frame section to DW_EH_PE_pcrel encoding. R_386_NONE and
R_X86_64_NONE are expected since the space for run-time relocation
has been allocated. This is an optimization.

[AArch64] Support RAS extension for ARMv8 onwards.
The RAS extension was introduced as part of the ARMv8.2 architecture
where it is a required feature. It is also available as an optional
feature for ARMv8 and ARMv8.1. In binutils, the RAS extension is
currently enabled by default for -march=armv8.2-a but is not available
for -march=armv8 or -march=armv8.1-a.
This patch adds the feature extension '+ras' to enable the RAS extension
for ARMv8 and ARMv8.1, it is disabled by default.

Cast the pointer assigned to ss_sp to char *.
FreeBSD versions older than 11.0 use char * as the type of ss_sp in
stack_t instead of the standards-defined void *. C++ allows a char *
pointer to be converted to a void *, so it is safe to cast the return
value of xmalloc to char * if ss_sp is either a char * or void *.
Just always use the cast to char * since that is less ugly than having
to add a special case.
gdb/ChangeLog:
* main.c (setup_alternate_signal_stack): Cast to char *.

Re-factor (i386|amd64)mpx target descriptions.
In the previous patch a new set of target descriptions
(i386|amd64)-avx-mpx were added being same as the (i386|amd64)-mpx.
This patch removes AVX feature from (i386|amd64)-mpx target
description set.
This way the (i386|amd64)avx_mpx(_linux|) set has AVX and MPX features
and (i386|amd64)mpx(_linux|) only MPX.

Add target descriptions for AVX + MPX
The current MPX target descriptions assume that MPX is always combined
with AVX, however that's not correct. We can have machines with MPX
and without AVX; or machines with AVX and without MPX.
This patch adds new target descriptions for machines that support
both MPX and AVX, as duplicates of the existing MPX descriptions.
The following commit will remove AVX from the MPX-only descriptions.

Fix PR gdb/19250: ptrace prototype is not detected properly in C++ mode
The ptrace args/return types detection doesn't work properly in C++
mode, on non-GNU/Linux hosts. For example, on gcc70 (NetBSD 5.1),
where the prototype is:
int ptrace(int, __pid_t, void*, int);
configure misdetects it as:
$ grep PTRACE_TYPE config.h
#define PTRACE_TYPE_ARG1 int
#define PTRACE_TYPE_ARG3 int *
#define PTRACE_TYPE_ARG4 int
/* #undef PTRACE_TYPE_ARG5 */
#define PTRACE_TYPE_RET int
resulting in:
../../src/gdb/amd64bsd-nat.c: In function 'void amd64bsd_fetch_inferior_registers(target_ops*, regcache*, int)':
../../src/gdb/amd64bsd-nat.c:56: warning: dereferencing type-punned pointer will break strict-aliasing rules
../../src/gdb/amd64bsd-nat.c: In function 'void amd64bsd_store_inferior_registers(target_ops*, regcache*, int)':
../../src/gdb/amd64bsd-nat.c:104: warning: dereferencing type-punned pointer will break strict-aliasing rules
../../src/gdb/amd64bsd-nat.c:110: warning: dereferencing type-punned pointer will break strict-aliasing rules
We could address this [1], however despite ptrace.m4's claim:
# Needs to be tested in C++ mode, to detect whether we need to cast
# the first argument to enum __ptrace_request.
it appears that there's actually no need to test in C++ mode. Always
running the ptrace tests in C mode works just the same on GNU/Linux.
I remember experimenting with several different ways to handle the
original issue back then, and maybe that was needed in some other
attempt and then I didn't realize it ended up not really necessary.
Confirmed that this fixes the NetBSD 5.1 C++ build, and confirmed that
C and C++ builds on Fedora 23 are unaffected.

Fix gdb crash when trying to print the address of a synthetic C++ reference
After compiling a program which uses C++ references some optimizations may
convert the references into synthetic "pointers". Trying to print the address
of one of such synthetic references causes gdb to crash with the following
error:
(gdb) print &ref
/build/buildd/gdb-7.7.1/gdb/dwarf2loc.c:1624: internal-error: Should not be able to create a lazy value with an enclosing type
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Apparently, what was causing it was that value_addr returns a copy of the value
that represents the reference with its type set to T* instead of T&. However,
its enclosing_type is left untouched, which fails a check made in
read_pieced_value. We only see the crash happen for references that are
synthetic because they're treated as pieced values, thus the call to
read_pieced_value.
On a related note, it seems that in general there are all sorts of breakage
when working with synthetic references. This is reported here:

remove pointless assignment
Presumably this was supposed to be regname[sizeof (regname) - 1] but was typoed
to regname[sizeof (rename) - 1]. However that should be unnecessary because
sprintf should null terminate. As is this assignment is invalid ISO C because
rename refers to the function rename (), and sizeof on functions is undefined.
In GNU C C the size of functions is 1 so the expression is the same as
regname[0]. The following call to sprintf () clearly will over right that, so
the statement either has no effect or is invalid. Given that it seems safe to
just remove it. While we are there correct the size of regname, and switch
from snprintf to sprintf since we know the exact length of the result.

MIPS/Linux: Also recognize TRAP_BRKPT and TRAP_HWBKPT
This makes the MIPS Linux backends recognize TRAP_BRKPT and
TRAP_HWBKPT in siginfo.si_code in addition to SI_KERNEL, since Linux
4.6 now reports the finer-grained si_code values too.
Refs:
https://sourceware.org/ml/gdb-patches/2016-02/msg00756.html
https://sourceware.org/ml/gdb-patches/2016-04/msg00090.html
On kernels that report SI_KERNEL (<= 4.5), we'll enter the "ambiguous"
path of save_stop_reason:
if (GDB_ARCH_IS_TRAP_BRKPT (siginfo.si_code)
&& GDB_ARCH_IS_TRAP_HWBKPT (siginfo.si_code))
{
/* The si_code is ambiguous on this arch -- check debug
registers. */
if (!check_stopped_by_watchpoint (lp))
lp->stop_reason = TARGET_STOPPED_BY_SW_BREAKPOINT;
}
while on kernels that report the finer-grained si_code values (>= 4.6),
we'll enter the corresponding branches:
else if (GDB_ARCH_IS_TRAP_BRKPT (siginfo.si_code))
{
}
else if (GDB_ARCH_IS_TRAP_HWBKPT (siginfo.si_code))
{
...
gdb/ChangeLog:

* nat/linux-ptrace.h [__mips__] (GDB_ARCH_IS_TRAP_BRKPT): Also
accept TRAP_BRKPT.

[ARM] minor opt in thumb_stack_frame_destroyed_p
thumb_stack_frame_destroyed_p scans the instructions from PC to the
end of the function, but if PC is far from the end of pc, we don't
have to scan, because PC should be in epilogue if it is still
far from the end of the function. The criterion I use here is 16
bytes, which is more than 4 instructions.
Regression tested on aarch64-linux with mutli-arch debug.

arc/nps400 : New cmem instructions and associated relocation
Add support for arc/nps400 cmem instructions, these load and store
instructions are hard-wired to access "0x57f00000 + 16-bit-offset".
Supporting this relocation required some additions to the arc relocation
handling in the bfd library, as well as the standard changes required to
add a new relocation type.
There's a test of the new instructions in the assembler, and a test of
the relocation in the linker.

* reloc.c: Add BFD_RELOC_ARC_NPS_CMEM16 entry.

bfd/arc: Rename enum entries to avoid conflicts
In bfd/elf32-arc.c an enum is created that contains entries with generic
names like 'NONE' and 'OFF'. This has been fine for now, but I had a
need to include opcode/arc.h into bfd/elf32-arc.c. Unfortunately
opcode/arc.h includes a different enum with identical generic names.
Given that changing the enum in the header file could mean wide-ranging
changes, while changing the enum in the .c file is limited to only
changing the one file, I've added a prefix to the enum in the .c file.
This commit does not add the new include, that will come later. There
should be no functional change with this commit.

Test GDB connection to GDBserver with no symbol files
This test exercises the scenarios where we attempt to connect GDB to GDBserver
in standard remote mode, query the symbol file path, attempt to open said
symbol file on GDB's end and fail, causing the connection to drop abruptly.
Regression-tested on x86-64/Ubuntu.
With an unpatched GDB we should see this:
FAIL: gdb.server/connect-with-no-symbol-file.exp: sysroot=: action=permission: connection to GDBserver succeeded (the program is no longer running)
FAIL: gdb.server/connect-with-no-symbol-file.exp: sysroot=: action=delete: connection to GDBserver succeeded (the program is no longer running)

Debugging without a binary (regression)
When we attempt to debug a process using GDBserver in standard remote mode
without a symbol file on GDB's end, we may run into an issue where GDB cuts
the connection attempt short due to an error. The error is caused by not
being able to open a symbol file, like so:
--
(gdb) set sysroot
(gdb) tar rem :2345
Remote debugging using :2345
/proc/23769/exe: Permission denied.
(gdb) i r
The program has no registers now.

This is caused by a couple of function calls within exec_file_locate_attach
that can potentially throw errors.
The following patch guards both exec_file_attach and symbol_file_add_main to
prevent the errors from disrupting the connection process.
There was also a case where native GDB tripped on this problem, but it was
mostly fixed by bf74e428bca61022bd5cdf6bf28789a184748b4d.

gdbserver-base.exp: Copy file to standard output directory in ${board}_download
gdbserver-base.exp is used as the base for both native-gdbserver.exp and
native-extended-gdbserver.exp. (Despite its name, it should really be
considered as a "local-gdbserver-base", as it's not really appropriate to
implement a remote gdbserver board.)
Currently, the _download procedure is implemented as a no-op (it returns
the source file path). Because of the SONAME change, The fast
tracepoint tests now require the executable and the IPA
(libinproctrace.so) to be located in the same directory (see [1]). When
using the native-gdbserver board, because _download returns the original
file path, the executable does not end up in the same directory as the
library, and it fails to execute.
In more general terms, with the recent changes, the testsuite now
assumes that when it does
${board}_download <source path 1> <destination path 1>
${board}_download <source path 2> <destination path 2>
where the destination paths are relative (generally just the file name),
both files will end up in the same base directory. That assumption does
not hold for the current implementation in gdbserver-base.exp.
The proper fix would be to make native-gdbserver non-remote, so that
gdb_remote_download would not call DejaGnu's remote_download (see [2]).
We could then get rid of ${board}_download in gdbserver-base.exp.
However, that will likely take some time to complete. In the mean time,
in order to make the fast tracepoint tests pass, we can simply copy the
file to the standard output directory. Basically, it just mimics what
gdb_remote_download would do if the board wasn't flagged as remote.
Note that I missed these failures originally because I had a
libinproctrace.so in /usr/local/lib. So, even though libinproctrace.so
wasn't copied to the test output directory, it did find the one in
/usr/local/lib. It would be nice to find a way to protect against this,
as it could easily happen again...
Regtested with unix, native-gdbserver and native-extended-gdbserver, and
didn't see anything notable, except the ftrace tests now passing for
native-gdbserver.

Fix aarch64 ftrace JIT condition testcase
This patch fixes the following failure:
FAIL: gdb.trace/trace-condition.exp: ftrace: -(21 << 1) == -42: check 10
frames were collected.
This was due to aarch64_emit_sub using the wrong order in its operands, so the
operation would end up being 42 - 0 rather than 0 - 42.
This patch also fixes the order of aarch64_emit_add for clarity.
The test case for emit_sub is fixed so that the proper order of
the operands is needed for the test to pass.
Tested on aarch64-native-extended-gdbserver.
Note: trace-condition.exp was broken a bit so I had to modify it to run
the test. A fix is coming for that in another patch.

support async mode), GDB 7.4 time. Later, GDB 7.8 switched to
target-async on by default, making the regression user-visible by

MIPS/GAS: Relax branches to symbols resolved at link time
Where branch relaxation is enabled emit the long sequence for branches
whose distance cannot be determined, i.e. to symbols that are undefined
or in a different segment. These symbols are only resolved at link time
and therefore the longer sequence ensures the branch target is in range,
which cannot be guaranteed with a direct branch.
This is the opposite to the current implementation, originally proposed
here: <https://sourceware.org/ml/binutils/2002-09/msg00218.html>. The
proposal was then extensively discussed before the final version was
posted here: <https://sourceware.org/ml/binutils/2002-10/msg00191.html>
and eventually committed:
commit 4a6a3df43dbb37853a7b88b10ae97d9ec5daf987
Author: Alexandre Oliva <aoliva@redhat.com>
Date: Sat Oct 12 05:23:33 2002 +0000
The case considered here was not commented in the review however and the
original version remains. With branch relaxation enabled it makes more
sense to do it consistently, so that all code impure with respect to
branch distances can be linked. Direct branches are still produced for
the cases concerned where branch relaxation is disabled, which is the
default.

target remote: Don't rely on immediate_quit (introduce quit handlers)
remote.c is the last user of immediate_quit. It's relied on to
immediately break the initial remote connection sync up, if the user
does Ctrl-C, assuming that was because the target isn't responding.
At that stage, since the connection isn't synced yet, disconnecting is
the only safe thing to do. This commit reworks that, to not rely on
throwing from the SIGINT signal handler.
So, this commit:
- Introduces the concept of a "quit handler". This is used to
override what does the QUIT macro do when the quit flag is set.
- Makes the "struct serial" reachar / write code call QUIT in the
partial read/write loops, so the current quit handler is invoked
whenever a serial->read_prim / serial->write_prim returns EINTR.
- Makes the "struct serial" reachar / write code call
interruptible_select instead of gdb_select, so that QUITs are
detected in a race-free manner.
- Stops remote.c from setting immediate_quit during the initial
connection.
- Instead, we install a custom quit handler whenever we're calling
into the serial code. This custom quit handler knows to immediately
throw a quit when we're in the initial connection setup, and
otherwise defer handling the quit/Ctrl-C request to later, when
we're safely out of a packet command/response sequence. This also
is what is now responsible for handling "double Ctrl-C because
target connection is stuck/wedged."
- remote.c no longer installs a specialized SIGINT handlers, and
instead re-uses the quit flag. Since we want to rely on the QUIT
macro, the SIGINT handler must also set the quit. And the easiest
is just to not install custom SIGINT handler in remote.c. Let the
standard SIGINT handler do its job of setting the quit flag.
Centralizing SIGINT handlers seems like a good thing to me, anyway.

Do target_terminal_ours in query & friends instead of in all callers
Any time a caller calls query & friends / prompt_for_continue without
ensuring that gdb owns the terminal for input is a bug. So do that in
defaulted_query / prompt_for_continue directly instead.
An example of a case where we currently miss calling
target_terminal_ours is internal_error. Ever since defaulted_query
was made to use gdb_readline_callback, there's no way to answer the
internal error query if the internal error happens while the target is
has the terminal:

ada-lang.c: Introduce type_as_string and use it
A couple wrong things here
- We should not use target_terminal_ours when all we want is output.
We should use target_terminal_ours_for_output instead, which
preserves raw/cooked terminal modes, and SIGINT forwarding.
- Most importantly, relying on stderr output immediately preceding
the error/exception print isn't correct. The exception could be
caught and handled, for example; MI frontends won't display the
stderr part in an error dialog box. Etc.
This commit introduces a type_as_string helper that allows building a
full error string including type info.

Fix inconsistent handling of EINTR in ser-*.c backends
- If serial->write_prim returns EINTR, ser_bas_write returns it to the
caller. This just looks wrong to me -- part of the output may have
already been sent, and there's no way for the caller to know that,
and thus no way for a caller to handle a partial write correctly.
- While ser-unix.c:ser_unix_read_prim retries on EINTR,
ser-tcp.c:net_read_prim does not.
This commit moves EINTR handling to the ser_base_write and
ser_base_readchar level, so all serial backends (at least those that
use it) end up handling EINTR consistently.

Pass Ctrl-C to the target in target_terminal_inferior
If the user presses Ctrl-C immediately before target_terminal_inferior
is called and the target is resumed, instead of after, the Ctrl-C ends
up pending in the quit flag until the target next stops.
remote.c has this bit to handle this:
if (!target_is_async_p ())
{
ofunc = signal (SIGINT, sync_remote_interrupt);
/* If the user hit C-c before this packet, or between packets,
pretend that it was hit right here. */
if (check_quit_flag ())
sync_remote_interrupt (SIGINT);
}
But that's only reachable if async is off, while async is on by
default nowadays. It's also obviously not reacheable on native
targets.
This patch generalizes that to all targets.
We can't remove that remote.c bit yet, until we get rid of the sync
SIGINT handler though. That'll be done later in the series.

Decouple target_interrupt from all-stop/non-stop modes
In non-stop mode, "interrupt" results in a "stop with no signal",
while in all-stop mode, it results in a remote interrupt request /

target_interrupt specifically always about "Interrupting as if with
Ctrl-C", just like it is documented.

Don't call clear_quit_flag in prepare_to_throw_exception
I think this is reminiscent of the time when a longjmp would always
jump to the top level. Nowaways code that throw exceptions other than
a quit, which may even be caught and handled without reaching the top
level. Certainly such exceptions shouldn't clear an interrupt
request...
(We also need to get rid of prepare_to_throw_exception in order to be
able to just do "throw ex;" in C++.)
One could argue that we should clear the quit flag when we throw a
quit from the SIGINT handler, when immediate_quit is in effect, to
handle a race, here:
immediate_quit++;
QUIT;
... that's the usual pattern code must use when enabling
immediate_quit. The QUIT is there to catch the case of Ctrl-C having
already been pressed before immediate_quit was enabled. However, this
can happen:
immediate_quit++;
<< Ctrl-C pressed here too.
QUIT;
And in that case, if the quit flag was already set, it'll stay set
even after throwing a quit from the SIGINT handler. The end result is
a double quit. But OTOH, the user did press Ctrl-C two times. Since
I'm getting rid of immediate_quit, I'm not bothering with this.

wrapped in throw_exception and friends, and this code was in an

Introduce interruptible_select
We have places where we call a blocking gdb_select expecting that a
Ctrl-C will unblock it. However, if the Ctrl-C is pressed just before
gdb_select, the SIGINT handler runs before gdb_select, and thus
gdb_select won't return.
For example gdb_readline_no_editing:
QUIT;
/* Wait until at least one byte of data is available. Control-C
can interrupt gdb_select, but not fgetc. */
FD_ZERO (&readfds);
FD_SET (fd, &readfds);
if (gdb_select (fd + 1, &readfds, NULL, NULL, NULL) == -1)
and stdio_file_read:
/* For the benefit of Windows, call gdb_select before reading from
the file. Wait until at least one byte of data is available.
Control-C can interrupt gdb_select, but not read. */
{
fd_set readfds;
FD_ZERO (&readfds);
FD_SET (stdio->fd, &readfds);
if (gdb_select (stdio->fd + 1, &readfds, NULL, NULL, NULL) == -1)
return -1;
}
return read (stdio->fd, buf, length_buf);
This is a race classically fixed with either the self-pipe trick, or
by blocking SIGINT and then using pselect instead of select.
Blocking SIGINT most of the time would mean that check_quit_flag (and
thus QUIT) would need to do a syscall every time it is called, which
sounds best avoided, since QUIT is called in many loops. Thus we take
the self-pipe trick route (wrapped in a serial event).
Instead of having all places that need this manually add an extra file
descriptor to the set of gdb_select's watched file descriptors, we
introduce a wrapper, interruptible_select, that does that.
The Windows version of gdb_select actually does not suffer from this,
because mingw-hdep.c:gdb_call_async_signal_handler sets a Windows
event that gdb_select always waits on. So this patch can be seen as
generalization of that technique. We can't remove that extra event
from mingw-hdep.c until we get rid of immediate_quit though.

Fix signal handler/event-loop races
GDB's core signal handling suffers from a classical signal handler /
mainline code race:
int
gdb_do_one_event (void)
{
...
/* First let's see if there are any asynchronous signal handlers
that are ready. These would be the result of invoking any of the
signal handlers. */
if (invoke_async_signal_handlers ())
return 1;
...
/* Block waiting for a new event. (...). */
if (gdb_wait_for_event (1) < 0)
return -1;
...
}
If a signal is delivered while gdb is blocked in the poll/select
inside gdb_wait_for_event, then the select/poll breaks with EINTR,
we'll loop back around and call invoke_async_signal_handlers.
However, if the signal handler runs between
invoke_async_signal_handlers and gdb_wait_for_event,
gdb_wait_for_event will block, until the next unrelated event...
The fix is to a struct serial_event, and register it in the set of
files that select/poll in gdb_wait_for_event waits on. The signal
handlers that defer work to invoke_async_signal_handlers call
mark_async_signal_handler, which is adjusted to also set the new
serial event in addition to setting a flag, and is thus now is
garanteed to immediately unblock the next gdb_select/poll call, up
until invoke_async_signal_handlers is called and the event is cleared.

Introduce a serial interface for select'able events
This patch adds a new "event" struct serial type, that is an
abstraction specifically for waking up blocking waits/selects,
implemented on top of a pipe on POSIX, and on top of a native Windows
event (CreateEvent, etc.) on Windows.
This will be used to plug signal handler / mainline code races.
For example, GDB can indefinitely delay handling a quit request if the
user presses Ctrl-C between the last QUIT call and the next (blocking)
gdb_select call in the event loop:
QUIT;
<<< press ctrl-c here and end up blocked in gdb_select
indefinitely.
gdb_select (...); // whoops, SIGINT was already handled, no EINTR.
A global alone (either the quit flag, or the "ready" flag of the async
signal handlers in the event loop) is not sufficient.
To plug races such as these on POSIX systems, we have to register some
waitable file descriptor in the set of files gdb_select waits on, and
write to it from the signal handler. This is classically a pipe, and
the pattern called the self-pipe trick. On Linux, it could be a more
efficient eventfd instead, but I'm sticking with a pipe for
simplifity, as we need it for portability anyway.
(Alternatively, we could use pselect/ppoll, and block signals until
the pselect. The latter is not a design I think GDB could use,
because we want the QUIT macro to be super cheap, as it is used in
loops. Plus, Windows.)
This is a "struct serial" because Windows's gdb_select relies on that.
Windows's gdb_select, our "select" replacement, knows how to wait on
all kinds of handles (regular files, pipes, sockets, console, etc.)
unlike the native Windows "select" function, which can only wait on
sockets. Each file descriptor for a "serial" type that is not
normally waitable with WaitForMultipleObjects must have a
corresponding struct serial instance. gdb_select then internally
looks up the struct serial instance that wraps each file descriptor,
and asks it for the corresponding Windows waitable handle.
We could use serial_pipe() to create a "struct serial"-wrapped pipe
that is usable everywhere, including Windows. That's what currently
python/python.c uses for cross-thread posting of events.
However, serial_write and serial_readchar are not designed to be
async-signal-safe on POSIX hosts. It's easier to bypass those when
setting/clearing the event source.
And writing and a serial pipe is a bit heavy weight on Windows.
gdb_select requires an extra thread to wait on the pipe and several
Windows events, when a single manual-reset Windows event, with no
extra thread is sufficient.
The intended usage is simply:
- Call make_serial_event to create a serial event object.
- From the signal handler call serial_event_set to set the event.
- From mainline code, have select/poll wait for serial_event_fd(), in
addition to whatever other files you're about to wait for.

Stop remote-fileio.c from throwing from SIGINT handler
This code installs a custom signal handler that throws a quit

that call is interruptible.
This is not only useful for switching to native C++ exceptions, but
AFAICS, also fixes a potential mess up of the remote protocol
connection, since there are target_read_memory calls done while
remote_fio_no_longjmp is clear. If the user presses ctrl-c while GDB
is sending or receiving a packet, we'll stop the communication
immediately, at a point where it isn't safe.

The need for the QUIT in stdin_event_handler is then exposed by the
gdb.base/double-prompt-target-event-error.exp test, which has:
# We're now stopped in a pagination query while handling a
# target event (printing where the program stopped). Quitting
# the pagination should result in only one prompt being
# output.
send_gdb "\003p 1\n"
Without that change we'd get:
Continuing.

^CpQuit

gdb/ChangeLog:

* event-top.c (stdin_event_handler): Call QUIT;
(prompt_for_continue): Don't run with immediate_quit set.

TUI: check whether in secondary prompt instead of immediate_quit
As can be seen in the tui_redisplay_readline comment:
"The command could call prompt_for_continue and we must not restore
SingleKey so that the prompt and normal keymap are used."
immediate_quit is being used as proxy for "secondary prompt".
We have a better predicate nowadays, so use it.
gdb/ChangeLog:
2016-04-12 Pedro Alves <palves@redhat.com>
* tui/tui-io.c (tui_redisplay_readline): Check
gdb_in_secondary_prompt_p instead of immediate_quit.
* tui/tui.c: Include top.h.
(tui_rl_startup_hook): Check gdb_in_secondary_prompt_p instead of
immediate_quit.

Don't rely on immediate_quit in command_line_input
AFAICS, immediate_quit was only needed here nowdays to be able to
interrupt gdb_readline_no_editing.
command_line_input can also take the gdb_readline_wrapper path, but
since that is built on top of the event loop (gdb_select / poll and
asynchronous signal handlers), it can be interrupted.
gdb/ChangeLog:
2016-04-12 Pedro Alves <palves@redhat.com>
* top.c: Include "gdb_select.h".
(gdb_readline_no_editing): Wait for input with gdb_select instead
of blocking in fgetc.
(command_line_input): Don't set immediate_quit.

Make gdb.server/solib-list.exp work for remote targets
There are a few small changes needed to make it work with a real remote
target.
- Remove the [is_remote target] check.
- Remove soname setting when building the lib, it's done by default now
anyway.
- In the compilation of the executable, pass the shared lib using the
shlib option, so that RPATH is set.
- Download the program to the target using gdb_remote_download, and
record the remote path. Remove loading of the program using
gdb_load_shlibs, which was not really appropriate anyway.
- Run the remote path through readlink (see comment in the code).
- Start gdbserver with the remote path.
Also, don't set executable and objfile variables, as they are unused.
Tested with native, native-gdbserver, native-extended-gdbserver, and a
remote gdbserver.
gdb/testsuite/ChangeLog:
* gdb.server/solib-list.exp: Remove is_remote check.
Pass shlib= to gdb_compile. Don't link shared library with
-soname. Call gdb_remote_download instead of gdb_load_shlibs.
Run binary filename through "readlink -f" on the target.

The copying comes from gdbserver_spawn ->
gdbserver_download_current_prog -> gdb_remote_download.
There's actually no need to download the interpreter to the target -
it's part of the target system/environment. So fix this by making the
test just not use gdb_load (and gdb_file_cmd as consequence) at all,
and instead pass the interpreter filename to gdbserver as an argument.

2016-04-08 Pedro Alves <palves@redhat.com>
* gdb.server/solib-list.exp: Don't use gdb_load. Instead pass the

value: Make accessor methods' parameters const-correct
I did a quick pass over value.c and value.h and made some of the accessor methods'
pass-by-reference parameters const-correct. Besides the obvious benefits, this is
required if we want to use them on values that are already declared as const
(such as the parameters to lval_funcs).
There's probably a lot more stuff that can be made const, here and elsewhere.

The compiled code's .debug_line is wrong (for the simplistic approach of GDB
to put a breakpoint on the first address belonging to that source line) and so
GDB misses the breakpoint at the last line:

Fix gdb.compile/compile.exp shlib regression
Commit 6e774b13c3b8 (Make ftrace tests work with remote targets) made
a few gdb.compile/compile.exp tests disappear:
-PASS: gdb.compile/compile.exp: call shared library function
-PASS: gdb.compile/compile.exp: expect 1
-PASS: gdb.compile/compile.exp: modify shared library variable
-PASS: gdb.compile/compile.exp: expect 15
This is because the test uses ldflags instead of using the shlib
option, so it misses linking with -rpath, resulting in:
(gdb) run
Starting program: .../compile/compile-shlib
.../compile/compile-shlib: error while loading shared libraries: compile-shlib.so: cannot open shared object file: No such file or directory

gas/arc: Handle multiple arc_opcode chains for same mnemonic
This commit completes support for having multiple instructions with the
same mnemonic in non-contiguous blocks within the arc_opcodes table.
The commit adds an iterator mechanism for the arc_opcode_hash_entry
structure, which is then used in find_opcode_match to consider all
arc_opcode entries with the same mnemonic, even when these instructions
are stored in non-contiguous blocks.
I extend the comment on the arc_opcodes table to discuss how entries
within the table are organised, and to mention how instructions can be
split into multiple groups if needed, but that the table is still
searched in table order.
There should be no user visible changes after this commit.
gas/ChangeLog:
* config/tc-arc.c (struct arc_opcode_hash_entry_iterator): New
structure.
(arc_opcode_hash_entry_iterator_init): New function.
(arc_opcode_hash_entry_iterator_next): New function.
(find_opcode_match): Iterate over all arc_opcode entries
referenced by the arc_opcode_hash_entry passed in as a parameter.
opcodes/ChangeLog:
* arc-opc.c (arc_opcodes): Extend comment to discus table layout.

gas/arc: Additional work to support multiple arc_opcode chains
Building on earlier commits, this commit moves along support for having
multiple arc_opcode entries in the arc_opcodes table that have the same
mnemonic (name) field, but are not stored in a contiguous block in the
table.
In this commit we support looking up the arc_opcode_hash_entry from the
hash table, and passing this along to the find_opcode_match function,
which then finds the specific arc_opcode that we're assembling. We
still don't actually support the multiple chains of arc_opcode entries
in this commit, but the limitation is now isolated to the
find_opcode_match function.
There is no user visible change after this commit.
gas/ChangeLog:
* config/tc-arc.c (arc_find_opcode): Now returns
arc_opcode_hash_entry pointer.
(find_opcode_match): Update argument type, extract arc_opcode from
incoming arc_opcode_hash_entry.
(find_special_case_pseudo): Update return type.
(find_special_case_flag): Update return type.
(find_special_case): Update return type.
(assemble_tokens): Lookup arc_opcode_hash_entry based on
instruction mnemonic, then use find_opcode_match to identify
specific arc_opcode.

gas/arc: Modify structure used to hold opcodes
The arc assembler builds a hash table to hold references to arc_opcode
entries in the arc_opcodes table. This hash assumes that each mnemonic
will always appear in a contiguous blocks within the arc_opcodes table;
all ADD instruction will be together, all AND instructions will likewise
be together and so on.
The problem with this is that as different variations of arc are added,
then it is often more convenient to split instructions apart, so all the
base ADD instructions are together, but, variants of ADD specific to one
variation of arc are grouped with other instructions specific to that
arc variant. The current data structures don't support splitting the
instructions in this way.
This commit is a first step towards addressing this limitation. In this
commit the hash table that currently holds arc_opcode pointers directly,
instead holds a pointer to a new, intermediate, data structure. This
new data structure holds the pointer to the arc_opcode. In this way, we
can, in the future support having the intermediate structure hold
multiple pointers to different arc_opcode groups.
There should be no visible functional change after this commit.
gas/ChangeLog:
* config/tc-arc.c (struct arc_opcode_hash_entry): New structure.
(arc_find_opcode): New function.
(find_special_case_pseudo): Use arc_find_opcode.
(find_special_case_flag): Likewise.
(assemble_tokens): Likewise.
(md_begin): Build hash using struct arc_opcode_hash_entry.

aarch64-linux, there is no prologue in void_func, so two breakpoints
are set at the same place (0x4007a0).

we can see breakpoint on 0x85f4 are inserted *twice*, but only removed
once. That is fine to remote target, because Z/z packets are
idempotent, but there is a leftover in record_full_breakpoints
in record-full target. The flow can be described as below,
record_full_breakpoints remote target
-----------------------------------------------------------------------
forward execution, continue, in_target_beneath 1 breakpoint inserted
insert breakpoints on 0x85f4 in_target_beneath 1
twice
program stops,
remove breakpoint on 0x85f4 in_target_beneath 1 breakpoint removed
reverse execution, continue, in_target_beneath 1 none is requested
insert breakpoints on 0x85f4, in_target_beneath 0
program stops,
remote breakpoint on 0x85f4, in_target_beneath 0 request to remove,
but GDBserver
doesn't know
now, the question is why breakoint on 0x85f4 is inserted twice? One
is the normal breakpoint, and the other is the single step breakpoint.
GDB inserts single step breakpoint to do single step. When program
stops at 0x85f4, both of them are set on 0x85f4, and GDB deletes
single step breakpoint, so in update_global_location_list, this
breakpoint location is no longer found, GDB call
force_breakpoint_reinsertion to mark it condition_updated, and insert
it again.
The reason force_breakpoint_reinsertion is called to update the
conditions in the target side, because the conditions may be
changed. My original fix is to not call force_breakpoint_reinsertion
if OLD_LOC->cond is NULL, but it is not correct if another location
on the same address has condition, GDB doesn't produce condition for
target side, but GDB should do.
Then, I change my mind back to make record-full handling breakpoint
idempotent, to align with remote target. Before insert a new entry
into record_full_breakpoints, look for existing one on the same
address first. I also add an assert on
"bp->in_target_beneath == in_target_beneath", to be safer.

Set bp_tgt->reqstd_address and bp_tgt->placed_size in record_full_insert_breakpoint
I notice that bp_tgt won't be fully initialized if to_insert_breakpoint
isn't called in record_full_insert_breakpoint, and bp_tgt->reqstd_address
is zero, so an entry is added to record_full_breakpoints, but its address
is zero, which is wrong. This patch is to call gdbarch_breakpoint_from_pc
in the else branch to set bp_tgt->reqstd_address and bp_tgt->placed_size.

ld/arc: Make little endian default choice for linker scripts
When building with --enable-targets=all the target string is not set to
something that matches the pattern arc*-*, and so the script used to
decide if we should build big or little endian linker script currently
exits with an error.
This commit makes little endian linker script be the default, which will
be used when building for all targets, this matches the behaviour from
before I made the endianness switchable, when we only ever built little
endian linker scripts anyway.

* emulparams/arc-endianness.sh: Make little endian default choice.

gas/arc: Allow greater range of characters into flag names
An upcoming commit will add a new arc instruction flag that uses
characters that have never appeared in an arc instruction flag before.
Currently the assembler is very conservative about which characters can
or cannot appear in an instruction flag.
This commit relaxes these constraints a little. After this commit all
alpha-numeric characters are now allowed into instruction flags. This
complete set is not required for the upcoming change, however, having
this slightly larger set does not impact the assemblers ability to
correctly parse input, but does make it easier to add new flag to the
instruction table.

gas/arc: Remove preprocess_operands function
The preprocess_operands function changes the incoming list of assembler
tokens based on the assumption that the first arc_operand found will be
the same instruction class as all of the arc_operands for the same
mnemonic.
Though this assumption is probably fine, removing this assumption, and
pushing the token change down into assemble_tokens makes the code no
more complex, and might even be easier to follow.
There should be no user visible changes after this commit.

Eliminate -var-create error for optzd ptr to struct
This patch eliminates an error thrown when accessing the value of a
pointer to a structure where the pointer has been optimized out and
'set print object' is 'on'. The error shows up as the rather ugly
value of the pointer variable in Eclipse.
If 'set print object' is 'on', GDB tries to determine the actual
(derived) type of the object rather than the declared type, which
requires dereferencing the pointer, which in this cases throws an
error because the pointer has been optimized out.
The fix is to simply ignore the 'print object on' setting for
pointers or references to structures when they have been optimized
out. This means we just get the declared type instead of the actual
type, because in this case that's the best that we can do.
To implement the fix, value_optimized_out was modified so that it
no longer throws an error when it fails to fetch the specified
value. Instead, it just checks value->optimized_out. If we can't
definitively say that the value is optimized out, then we assume
it is not.

Optimized-out pointer: New test for error handling
This patch implements a test that ensures that with "set print object
on", -var-create returns "<optimized out>" for an optimized out pointer
to structure, rather than throwing an error, while also ensuring that
any attempt to dereference the pointer *will* throw an error.
It uses the dwarf assembler to construct the appropriate debug info
to represent a pointer-to-struct in the program as optimized out,
and then accesses that pointer in various ways. The test uses both
the console interpreter and the MI interpreter.

Workaround gdbserver<7.7 for setfs
With current FSF GDB HEAD and old FSF gdbserver I expected I could do:
gdb -ex 'file target:/root/redhat/threadit' -ex 'target remote :1234'
(supplying that unsupported qXfer:exec-file:read by "file")
But that does not work because:
Sending packet: $vFile:setfs:0#bf...Packet received: OK
Packet vFile:setfs (hostio-setfs) is supported
...
Sending packet: $vFile:setfs:104#24...Packet received: OK

GDB documentation says:

An empty response indicates that this operation is not recognized.
This "empty response" vs. "OK" was a bug in gdbserver < 7.7. It was fixed by:

ld/arc: Fix linker for big-endian arc targets
This aims to bring the linker for big-endian arc targets into line with
the linker for (the default) little endian arc targets.
The bulk of the changes are to extend the target pattern in the test
files from 'arc-*...' to 'arc*-*...' and so match both big and little
endian arc targets.
In the ld/emulparams/ directory the existing scripts checked for a
variable ARC_ENDIAN to switch between big and little endian targets,
however, this variable is never set up.
So, a new script snippet is introduced which sets up ARC_ENDIAN based on
the value of target, this snippet is then included from all of the
existing arc scripts.
The existing big-endian variants of all the scripts, which existed, but
were never used, are deleted in this commit.

Make ftrace tests work with remote targets
When we build a shared library for testing, it is built differently
whether it is meant for the local system or a remote one. When it is
for the local system, the library is built with no SONAME. So when the
executable is built, roughly in this way:
$ gcc testfile.c /path/to/library.so
the executable will contain an absolute reference to the library. For
example:
$ readelf -a testsuite/gdb.python/py-shared | grep NEEDED
0x0000000000000001 (NEEDED) Shared library: [/home/emaisin/build/binutils-gdb/gdb/testsuite/gdb.python/py-shared-sl.sl]
When testing is done remotely, the absolute path obviously doesn't work.
Therefore, we build the library with an SONAME:
$ readelf -a testsuite/gdb.python/py-shared-sl.sl | grep SONAME
0x000000000000000e (SONAME) Library soname: [py-shared-sl.sl]
which ends up in the executable's NEEDED field:
$ readelf -a testsuite/gdb.python/py-shared | grep NEEDED
0x0000000000000001 (NEEDED) Shared library: [py-shared-sl.sl]
The executable and the library are then uploaded side-by-side on the
remote system. To allow the dynamic linker to find the shared library,
we have to add the special RPATH value $ORIGIN, which tells it to search
in the executable's directory:
$ readelf -a testsuite/gdb.python/py-shared | grep ORIGIN
0x000000000000000f (RPATH) Library rpath: [$ORIGIN]
The problem with the IPA library is that it doesn't have an SONAME,
making it very difficult to do testing on a remote board. When a
test executable is linked with it, it contains an absolute reference to
the library path. Therefore, unless the paths on the target are the
same as on the build system, it won't work.
To make it possible for tests using the IPA library to run test on
remote boards, I suggest adding an SONAME to libinproctrace.so. I don't
think it should be a big problem for users. All the libraries installed
on my system have an SONAME, so it should be fine if libinproctrace.so
does too.
As a consequence, native testing does not work anymore, since
executables do not contain the absolute path to the library anymore. To
keep them working, we can have gdb_load_shlibs copy the library to the
test directory when testing natively. That's done by modifying
gdb_load_shlibs. We also have to add RPATH=$ORIGIN to executables, even
when testing natively.
I think it's a good change in general, as it reduces the differences
between testing a native and a remote target. To further reduce those
differences, we can also always build test shared libraries with an
SONAME.
ftrace.exp and ftrace-lock.exp need to be modified slightly. The code
checks that the IPA library is loaded using the absolute path on the
build machine. That obviously doesn't work if the test is done
remotely, as the path will be different. I changed the tests to only
search for the library basename (e.g. libinproctrace.so).
gdb/gdbserver/ChangeLog:
* Makefile.in ($(IPA_LIB)): Set SONAME of the IPA lib.
gdb/testsuite/ChangeLog:
* gdb.trace/ftrace-lock.exp: Check for IPA basename instead of
absolute.

Improve gdb_remote_download, remove gdb_download
This patch removes gdb_download in favor of gdb_remote_download, since
they are very close in functionality. Also, in preparation for the
following patch about shared library handling during tests, it improves
gdb_remote_download so that it uses standard_output_file for any
destination board that is local, not only host.
If the destination board is remote, gdb_remote_download will use the
standard remote_download from DejaGnu, resulting in the file being
transferred on the remote system.
If the destination is local, gdb_remote_download will copy the file to
the standard test directory (found using standard_output_file). Tcl's
file copy seems to handle gracefully cases where the source file is the
same as the destination, so I don't think it's necessary to check for
that case ourselves, as a previous version of the patch did.
I'd prefer to keep the name gdb_download instead of gdb_remote_download,
since I don't like the fact that gdb_remote_download implies that the
destination is remote, when it's not always the case. However,
gdb_remote_download is used at many more places than gdb_download, so
it's easier to reuse that. Also, since it's a wrapper around DejaGnu's
remote_download, it might be better to keep that name. I don't know.
I ran the testsuite native, with native-gdbserver and with a
remote gdbserver, and didn't see any related failure.
gdb/testsuite/ChangeLog:
* gdb.base/jit-so.exp: Use gdb_remote_download instead of
gdb_download. Use it even if the target is not remote.
* gdb.base/jit.exp (compile_jit_test): Likewise.

ELF/LD: Avoid producing hidden and internal dynamic symbols
Always turn hidden and internal symbols which have a dynamic index into
local ones. This is required by the the ELF gABI[1]:
"A hidden symbol contained in a relocatable object must be either
removed or converted to STB_LOCAL binding by the link-editor when the
relocatable object is included in an executable file or shared object."
"An internal symbol contained in a relocatable object must be either
removed or converted to STB_LOCAL binding by the link-editor when the
relocatable object is included in an executable file or shared object."
The ELF linker usually respects this requirement, however in the case
where a dynamic symbol has been preallocated due to a reference of the
default export class aka visibility from the object being linked, and
then merged with a hidden or internal symbol definition from within the
same object, then the original export class is carried over to the
output dynamic symbol table, because while merging the generic ELF
linker only converts affected dynamic symbols to local when they are
defined or referenced by the object being linked and a dynamic object
involved in the link both at a time.
The dynamic symbol produced confuses then the dynamic loader at the run
time -- the hidden or internal export class is ignored and the symbol
follows preemption rules as with the default export class.
In the MIPS target it happens when `mips_elf_record_global_got_symbol'
creates a dynamic symbol when a call relocation is encountered.
Additionally if the undefined symbol referred by such a relocation does
specify the intended export class, then a local dynamic symbol is
created instead, which is harmless and allowed, but useless. Normally
no local dynamic symbols are created, except for a single dummy one at
the beginning.
Correct the problem by removing the extra check for a dynamic symbol
being defined or referenced by the object being linked and a dynamic
object involved in the link both at a time. The test cases included
cover the internal and hidden symbol cases, as well as a protected
symbol for a reference, the handling of which is unchanged by this fix.
Both cases described above are covered, that is where an internal or
hidden dynamic symbol is produced and where a local one is.
NB this change affects CRIS results where some symbols in the static
table produced in a final link are now converted from STV_HIDDEN to
STB_LOCAL. This happens whenever the `elf_backend_hide_symbol' handler
is called, so the affected symbols must have been chosen for entering
into the dynamic symbol table, except in these test cases no such symbol
table is produced. In fully linked binaries the static symbol table is
only used for debugging though, so such a change is fine.

gdb: allow enumeration constants as second operand of BINOP_REPEAT
This patch adds support for TYPE_CODE_ENUM values to be supplied
as right-hand side operand of the BINOP_REPEAT (@) operator. The
following should now work:
enum {
sz = 17
};
int
main ()
{
int arr[sz + 1] = { 0 };
return 0; /* line 9 here */
}
(gdb) b 9
(gdb) r
(gdb) p arr@sz
$1 = {0 <repeats 17 times>}
(gdb)
A couple of tests is also included in this patch to demonstrate that it is
working as intended.

PR19886, --as-needed regression
This isn't perfect in checking whether libraries will be loaded since
elf_link_add_object_symbols doesn't recurse down DT_NEEDED links.
(That happens later in ld/emultempl/elf32.em after_open.) So in
effect this recursive check really only looks one level down the
DT_NEEDED tree. Which is enough for the most common case, and
libc.so/ld.so in particular.

and a13c46966d308297a1273e35ccc807a3912d573d . One is a simple
missing cast, the other is const usage on global function pointers
exported from IPA: in C++, consts are static, and thus won't be
exported from the DSO (the build error was because of non-applicable
visibility("default")).

Fix PR gdb/19858: GDB doesn't register the JIT libraries on attach
Ref: https://sourceware.org/ml/gdb/2016-03/msg00023.html
GDB currently fails to fetch the list of already-registered JIT
modules on attach.
Nothing is calling jit_inferior_init, which is what is responsible for
walking the JIT object list at init time.
Despite the misleading naming, jit_inferior_created_hook ->
jit_inferior_init is only called when the inferior execs.
This regressed with the fix for PR gdb/13431 (03bef283c2d3):
https://sourceware.org/ml/gdb-patches/2012-02/msg00023.html which
removed the inferior_created (jit_inferior_created_observer)
observer.
Adding an inferior_created observer back fixes the issue.
In turn, this exposes a bug in jit_breakpoint_re_set_internal as well,
which is returning the wrong result when we already have the
breakpoint at the right address.

IPA: Add alloc_jump_pad_buffer target hook.
Targets may have various requirements on the required location of the jump
pad area. Currently IPA allocates it at the lowest possible address,
so that it is reachable by branches from the executable. However, this
fails on powerpc, which has executable link address (0x10000000) much
larger than branch reach (+/- 32MiB).
This makes jump pad buffer allocation a target hook instead. The current
implementations are as follows:
- i386 and s390: Branches can reach anywhere, so just mmap it. This
avoids the linear search dance.
- x86_64: Branches have +/-2GiB of reach, and executable is loaded low,
so just call mmap with MAP_32BIT. Likewise avoids the linear search.
- aarch64: Branches have +-128MiB of reach, executable loaded at 4MiB.
Do a linear search from 4MiB-size downwards to page_size.
- s390x: Branches have +-4GiB of reach, executable loaded at 2GiB.
Do like on aarch64.

When gdb is started in MI mode, the output of gdb.execute

To assure consistent output format, this is fixed by using the console

make xtensa_section_rename () take const char *
Xtensa uses it in several macros passing it a literal string, so its convenient
for the argument type to be const char *. However some of the code in
symbols.c seems to assume tc_canonicalize_symbol_name () will return a non
const pointer, and some other target's implementations even modify the
argument, so it seems best to return a char * which means casting away const on
the argument when we return it instead of another string.

tc-i960.c: add some casts when assigning literals to args[i]
parse_ldconst () takes a char ** as a in / out argument, and sometimes points
args[0] to a constant string. Then in some cases after parse_ldconst ()
returns md_assemble () twiddles the contents of arg[0]. So it seems like
it would take some work to avoid these casts, and its not really clear
that work is worth it.

cast the arg to md_assemble () to char *
For these targets its not clear how md_assemble can usefully be split up so
that part can take const char *. There is also a fair number of targets that
need md_assemble () to take a char *, so we can't easily make the argument
const. So since there isn't many callers it seems easiest to just add a couple
of casts.

work around get_symbol_name () in sparc and ia64
get_symbol_name () returns a char * in a out arg, which means we need to cast
to assign a literal to the variable passed to get_symbol_name (). It seems

cast literal to char * when assigning to input_line_ptr
various places either directly or indirectly set input_line_pointer to point at
a literal. Currently lots of places modify the string input_line_pointer
points at, so making it const isn't easy. Since most if not all of these
places assign to input_line_pointer to parse an expression it would probably be
best to add ways to generate and deal with expressions that doesn't involve
parsing strings, but for now adding some casts seems easiest.

Don't override definition a shared object by one in a later shared object.
In PR 16979, a reference to malloc is being resolved to an unversioned
reference in libmalloc.so. When linked with --as-needed, however, the
dynamic table does not list libmalloc.so as a DT_NEEDED library.
If we have a reference to an unversioned symbol in a shared object,
and we later see a versioned definition in another shared object, we
were overriding the first definition with the second in the process of
defining the default version. As a result, we no longer think that the
first shared object was actually needed to resolve any symbols, and we
don't list it as a DT_NEEDED library.
This patch fixes the problem by treating the two definitions as separate
symbols, so the second definition does not override the first.

gdbserver/IPA: Export some functions via global function pointers.
On powerpc64, qSymbol for a function returns the function code address,
and not the descriptor address. Since we emit code calling gdb_collect
and some other functions, we need the descriptor (no way to know the
proper TOC address without it). To get the descriptor address, make
global function pointer variables in the IPA pointing to the relevant
functions and read them instead of asking for them directly via qSymbol.

#0 0x76ff65a2 in shr1 () from /home/yao/Source/gnu/build/gdb/testsuite/gdb.reverse/shr1.sl
#1 0x0000869e in main () at /home/yao/Source/gnu/build/gdb/testsuite/../../../binutils-gdb/gdb/testsuite/gdb.reverse/solib-reverse.c:34
Backtrace stopped: previous frame inner to this frame (corrupt stack?)
(gdb) disassemble shr1
Dump of assembler code for function shr1:

0x76ff65a2 <+18>: bx lr
End of assembler dump.
in this case, prologue unwinder is used. It analyzes the prologue and
get the offsets of saved registers to SP. However, in epilogue, the
SP has been restored, prologue unwinder gets the registers from the
wrong address, and even the frame id is wrong.
In reverse debugging, this case (program stops at the last instruction
of function) happens quite frequently due to the reverse execution.
There are many test fails due to missing epilogue unwinder.
This adds epilogue unwinder, but the frame cache is still get by
prologue unwinder except that SP is fixed up separately, because SP
is restored in epilogue.
This patch fixes many fails in solib-precsave.exp, and solib-reverse.exp.

Refactor arm_stack_frame_destroyed_p
This patch is to refactor arm_stack_frame_destroyed_p, so that the code
can be used in both arm_stack_frame_destroyed_p and arm epilogue
unwinder I am going to add in the next patch. In fact, the code
is the same in two places, but checking whether it is thumb mode
is slightly different. arm_stack_frame_destroyed_p uses
arm_pc_is_thumb, and epilogue unwinder should use arm_frame_is_thumb.

Simplify gdb.reverse/until-reverse.c
Nowadays, functions fprintf, printf and malloc are executed in
gdb.reverse/until-reverse.c, so that it takes much time to record
instructions inside them. This may cause timeout, and we had several

(gdb) FAIL: gdb.reverse/until-precsave.exp: run to end of main (got interactive prompt)
however, I can't figure out how these functions (fprintf, printf and
malloc) are related to the test itself. marker1 is a function from
shared library too so we don't need these complicated libc functions
at all. IMO, recording the instructions in these libc functions has
nothing to do with the test itself except slow down the test. This
patch is to remove the usage of fprintf and printf, and also move
malloc to a dead code path.

gdbserver: Handle 'v' packet while processing qSymbol.
On powerpc64, qSymbol query may require gdb to read a function
descriptor, sending a vFile packet to gdbserver. Thus, we need
to handle 'v' packet in look_up_one_symbol.
vFile replies may be quite long, and require reallocating own_buf.
Since handle_v_requests assumes the buffer is the static global own_buf
from server.c and reallocates it, we need to make own_buf global and
use it from look_up_one_symbol instead of using our own auto variable.
I've also done the same change in relocate_instruction, just in case.
On gdb side, in remote_check_symbols, rs->buf may be clobbered by vFile
handling, yet we need its contents for the reply (the symbol name is
stored there). Allocate a new buffer instead.
This broke fast tracepoints on powerpc64, due to errors in reading IPA
symbols.
gdb/ChangeLog:
* remote.c (remote_check_symbols): Allocate own buffer for reply.
gdbserver/ChangeLog:
* remote-utils.c (look_up_one_symbol): Remove own_buf, handle 'v'
packets.
(relocate_instruction): Remove own_buf.
* server.c (own_buf): Make global.
(handle_v_requests): Make global.
* server.h (own_buf): New declaration.
(handle_v_requests): New prototype.

gdbserver/s390: Add fast tracepoint support.
Fast tracepoints will only work on 6-byte intructions, and assume at least
a z900 CPU. s390 also has 4-byte jump instructions, which also work on
pre-z900, but their range is limitted to +-64kiB, which is not very useful
(and wouldn't work at all with current jump pad allocation).
There's a little problem with s390_relocate_instruction function: it
converts BRAS/BRASL instructions to LARL of the return address + JG
to the target address. On 31-bit, this sets the high bit of the target
register to 0, while BRAS/BRASL would set it to 1. While this is not
a problem when the result is only used to address memory, it could
possibly break something that expects to compare such addresses for
equality without first masking the bit off. In particular, I'm not sure
whether leaving the return address high bit unset is ABI-compliant
(could confuse some unwinder?). If that's a problem, it could be fixed
by handling it in the jump pad (since at that point we can just modify
the GPRs in the save area without having to worry about preserving
CCs and only having that one GPR to work with - I'm not sure if it's
even possible to set the high bit with such constraints).

make md_parse_option () take a const char *
This is mostly just adding const in many places, however there are a couple
interesting things. We need to add casts in tc-s390.c and tc-cris.c because
they have functions that assign to input_line_pointer an argument that
sometimes comes from md_parse_option. Presumably this is safe because those
targets never pass literals to md_parse_option (), but this code should
probably be improved in the future. Also xtensa passes the argument to strtoll
which is a rather odd function, it takes a const char * as argument and returns
a pointer into that string as a char * through an out argument, but we can work
around that by adding more variables.

gas: sparc: allow ASR registers in the 0..31 range in V9 and later
In the SPARC V9 (and later) versions of the SPARC specification, the
section C.1.1 "Register Names" specifies that:
"asr_reg. An asr_reg is an Ancillary State Register name. It may have
one of the following values:
%asr16-%asr31"
The rationale of having this restriction was that the registers from 16
to 31 are reserved to implementations, and are therefore "non-V9". It
also assumes that the existing ASR registers in the range 0..31 will
have their own names such as %y, that can be used to access such
registers.
However, this is problematic. When a new ASR register is introduced,
such as %mcdper a.k.a. %asr14, it is useful to be able to use %asr14 in
order to not depend on the latest version of the assembler.
The Solaris assembler is lax and allows to assembly instructions
referring to %asr0 to %asr31. This patch makes the GNU assembler to
mimic that behavior.
gas/ChangeLog:
2016-03-24 Jose E. Marchesi <jose.marchesi@oracle.com>
* config/tc-sparc.c (sparc_ip): Remove the V9 restriction on ASR

instruction.

make microblaze build with -Wwrite-strings
frag_var () assigns its last argument to frag::fr_opcode, and it turns out
some targets modify the string that points to. However it appears niether the
generic code or the microblaze code modifies what fr_opcode points to, so this
code should be safe. So we unfortunately need to cast to char * when passing
an argument to frag_var () but otherwise microblaze can itself point to these
strings with const char *.

Fix problem where gold fails to issue an undefined symbol error during LTO.
During LTO, if (1) an IR file contains a COMDAT group that is kept,
(2) a later non-claimed file contains the same group, which we discard,
and (3) the plugin fails to provide a definition of the symbols in that
COMDAT group, gold silently resolves any references to those symbols
to 0.
This patch adds a check for a placeholder symbol when deciding
whether to issue an undefined symbol error. It also adds an extra
note after any undefined placeholder symbol error that explains
that a definition was expected from the plugin.

arc/opcodes: Use flag operand class to handle multiple flag matches
When parsing the operand instruction flags we don't currently detect the
case where multiple flags are provided from the same class set, these
will be accepted and the bit values merged together, resulting in the
wrong instruction being assembled. For example:
adc.n.eq r0,r0,r2
Will assemble without error, yet, upon disassembly, the instruction will
actually be:
adc.c r0,r0,r2
In a later commit the concept of required flags will be introduced.
Required flags are just like normal instruction flags, except that they
must be present for the instruction to match. Adding this will allow
for simpler instructions in the instruction table, and allow for more
sharing of operand extraction and insertion functions.
To solve both of the above issues (multiple flags being invalid, and
required flags), this commit reworks the flag class mechanism.
Currently the flag class is never used. Each instruction can reference
multiple flag classes, each flag class has a class type and a set of
flags. However, at present, the class type is never used. The current
values identify the type of instruction that the flag will be used in,
but this is not required information.
Instead, this commit discards the old flag classes, and introduces 3 new
classes. The first F_CLASS_NONE, is just a NULL marker value, and is
only used in the NULL marker flag class. The other two flag classes are
F_FLAG_OPTIONAL, and F_FLAG_REQUIRED.
The class F_FLAG_OPTIONAL has the property that at most one of the flags
in the flag set for that class must be present in the instruction. The
"at most" one means that no flags being present is fine.
The class F_FLAG_REQUIRED is not currently used, but will be soon. With
this class, exactly one of the flags from this class must be present in
the instruction. If the flag class contains a single flag, then of
course that flag must be present. However, if the flag class contained
two or more, then one, and only one of them must be present.

arc: Add nps400 machine type, and assembler flag.
This commit introduces the nps400 machine type as a variant of arc.
There's a new flag in the assembler to select this machine type. All
other changes are just adding handling of the new machine type into the
relevant places.
The nps400 is an arc700 variant with some vendor specific instructions
added into the instruction set. This commit does not add any of the new
instructions, this is just laying the groundwork for future commits.
However, in preparation for these new instructions a new opcode define for
nps400 has been added to include/opcode/arc.h, this new opcode define is
used in the assembler and disassembler along with the existing define
for arc700 such that when assembling and disassembling for nps400 the
user will have access to all arc700 instructions and all the nps400
vendor extension instructions.

arc: Remove EF_ARC_CPU_GENERIC constant.
The constant EF_ARC_CPU_GENERIC is defined in the include/elf/arc.h
file, and is used in a few places in binutils, however, this constant
should never make it into the elf header flags; we always set a valid
cpu type in the assembler, which should then be copied over during
linking.
There are some non-gnu arc compilers that don't write an architecture
type into the e_flags field, instead leaving the field as 0, which is
the EF_ARC_CPU_GENERIC value. This non-gnu compiler uses the machine
type to distinguish between the old and newer arc architectures, setting
the machine type to EM_ARC_COMPACT for old arc600, arc601, and arc700
architectures, while using EM_ARC_COMPACT2 for newer arcem and archs
architectures.
Previously when displaying the machine flags for an older EM_ARC_COMPACT
machine, if the e_flags had not been filled in, then we relied on the
default case statement to display the message "Generic ARCompact", while
in the EM_ARC_COMPACT2 case we specifically handled EF_ARC_CPU_GENERIC
to print "ARC Generic", leaving the default case to print a message
about unrecognised cpu flag.
After this commit EF_ARC_CPU_GENERIC has been removed, for both machine
types EM_ARC_COMPACT and EM_ARC_COMPACT2 we now rely on the default case
statement to handle the situation where the e_flags has not been filled
in. The message displayed is now "Unknown ARCompact" (for older arc
architectures) and "Unknown ARC" (for the newer architectures). The
switch from "Generic" to "Unknown" in the message string is for clarity,
calling the file "Generic" can give the impression that the file is
compiled for a common sub-set of the architectures, and would therefore
run on any type of machine (or at least any type of new or old machine
depending on if the machine type is ARC or ARCv2). However, this was
not what "Generic" meant, it really meant "Unknown", so that's what we
now say.
As part of the merging of the readelf flag reading code, I have unified
the strings used in displaying the ELF ABI. This means that for older
arc machines (arc600, arc601, and arc700) the string used for the
original ABI, and ABIv2 have changed, the current ABIv3 remains the
same. For the newer architectures (arcem and archs) the abi strings
remain unchanged in all cases.

* elf32-arc.c (arc_elf_print_private_bfd_data): Remove use of

This commit restructures the selection of the default cpu/mach so that
the choice is made from md_begin (if the user has not provided a command

At the request of Synopsys, the default architecture changes to ARC700
from this commit, previously the default was a non-existent

variants. There's some clean up associated with removing the default
merged architecture, and a small test fix now that the default is

gas/arc: Fix test for big-endian arc
The inline-data test checks the specific bytes laid down by the
assembler, and so relies on the endianness of the target. I could
change the expected results to be endian agnostic, however, I worried

slip through. Instead I add a new test for big-endian arc, and restrict
the existing test to little-endian arc.

Fix problem where gold cannot build .eh_frame_hdr from ld -r output.
When running ld -r on objects that have comdat groups, when gold
deduplicates a function in a comdat group, it removes the relocations
from the EH information that referred to the dropped copy of the function.
When running a final link using the result of the -r link, the missing
relocation cause it to fail to recognize the FDE for the dropped
function.
This patch improves gold's FDE scanning to take into account the
possibility that an FDE corresponds to a dropped function, and drops
that FDE as well.
Gnu ld, on the other hand, leaves the relocations in the ld -r output,
but makes them R_NONE with an r_sym field of 0. This was sufficient to
let both linkers recognize the FDE properly.
With this fix, if you do an ld -r with gold, then do the final link with
Gnu ld, the .eh_frame_hdr section will not be generated. To make it work
with Gnu ld, we would have to leave the R_NONE relocations in, but I
think it's better to drop the relocations entirely. I'd hope that if
you're doing a -r link with gold, you'll also do the final link with
gold.

tc-i386.c: store encoded instructions in unsigned char[]
char can be a signed type, and some of the values in these arrays are greater
than 0x80 which means they are outside of the range a signed char can store.
Fortunately it seems most compilers handle this in the obvious way by storing
the same bits as a negative number, but this is wierd and easily fixed.

Set signal to 0 after enqueue_pending_signal
Today, we enqueue signal in linux_resume_one_lwp_throw, but set
variable 'signal' many lines below with the comment
/* Postpone any pending signal. It was enqueued above. */
signal = 0;
I feel difficult to associate code across many lines, and we should
move the code close to enqueue_pending_signal call. This is what
this patch does in general. After this change, variable 'signal'
is set to zero very early, so the 'signal' value in the following
debugging message makes no sense, so I remove it from the debugging
message. The function returns early if lwp->status_pending_p is
true, so 'signal' value in the debugging message doesn't matter,
AFAICS. Also, I move one debugging message several lines below to
make it close the real ptrace call,
if (debug_threads)
debug_printf ("Resuming lwp %ld (%s, signal %d, stop %s)\n",
lwpid_of (thread), step ? "step" : "continue", signal,
lwp->stop_expected ? "expected" : "not expected");
so that the debugging message can reflect what GDBserver does. This
is a code refactor and only debugging messages are affected.

gdb -p <pid from a container>
will print:
warning: Target and debugger are in different PID namespaces; thread lists and other data are likely unreliable
It correctly states the problem but it does not say how to solve it.
Originally I wanted to suggest also the Docker "-p 1234:1234" parameter but
I see the containers are more general topic than just Docker (even LxC etc.).
According to Gary future GDBs should be able to work even without gdbserver.
But currently gdbserver is still required.

PR remote/19496, timeout in forking-threads-plus-bkpt
This patch addresses a failure in
gdb.threads/forking-threads-plus-breakpoint.exp:
FAIL: gdb.threads/forking-threads-plus-breakpoint.exp: cond_bp_target=1:
detach_on_fork=on: inferior 1 exited (timeout)
Cause:
A fork event was reported to GDB before GDB knew about the parent
thread, followed immediately by a breakpoint event in a different
thread. The parent thread was subsequently added via
remote_notice_new_inferior in process_stop_reply, but when the thread
was added the thread_info.state was set to THREAD_STOPPED. The fork
event was then handled correctly, but when the fork parent was resumed
via a call to keep_going, the state was unchanged.
The breakpoint event was then handled, which caused all the
non-breakpoint threads to be stopped. When the breakpoint thread was
resumed, all the non-breakpoint threads were resumed via
infrun.c:restart_threads. Our old fork parent wasn't restarted,
because it still had thread_info.state set to THREAD_STOPPED.
Ultimately the program under debug hung waiting for a pthread_join
while the old fork parent was stopped forever by GDB.
Fix:
Since this is non-stop, then the bug is that the thread should have
been added in THREAD_RUNNING state. Consider that infrun may be
pulling target events out of the target_ops backend into its own event
queue, but, not process them immediately. E.g., infrun may be
stopping all threads temporarily for a step-over-breakpoint operation
for thread A (stop_all_threads). The waitstatus of all threads is
thus left pending in the thread structure (save_status), including the
fork event of thread B. Right at this point, if the user does "info
threads", that should show thread B (the fork parent) running, not
stopped, even if internally, gdb is holding it paused for a little
bit.
Thus if in non-stop mode, always add new threads in the external
user-visible THREAD_RUNNING state. Change remote_notice_new_inferior
to accept the internal executing state of the thread instead, with
EXECUTING set to 1 when we discover a thread that is running on the
target (such as through remote_update_thread_list), and 0 when the
thread is really paused (such as when we see a stop reply).
Tested on x86_64 Linux and Nios II Linux target with x86 Linux host.

Since test artifacts are organized in a directory hierarchy, the

linux-record: Simplify with record_mem_at_reg()
The function record_linux_system_call() often records a memory area
whose address is contained in a register. So far this required two
function calls: one for fetching the register value, and another one for
recording the memory area. These two function calls are now merged into
a new local helper function, and all occurrences are adjusted. This
reduces the source code and makes it more readable.

* linux-record.c (record_mem_at_reg): New helper function.
(record_linux_system_call): Exploit new helper function where

linux-record: Fix bad fall-through for pipe/pipe2
This patch added handling for some syscalls to linux-record.c:
https://sourceware.org/ml/gdb-patches/2015-10/msg00452.html
But for both `pipe' and `pipe2' the patch lacks a statement after an
`if', such that the following `break' is interpreted as the `if'-body
instead.
This adds the missing (return-) statements for the conditionals.
gdb/ChangeLog:
* linux-record.c (record_linux_system_call): Add missing return
statements to handling of pipe and pipe2 syscalls.

PR remote/19496, interrupted syscall in forking-threads-plus-bkpt
This patch addresses "fork:Interrupted system call" (or wait:) failures
in gdb.threads/forking-threads-plus-breakpoint.exp.
The test program spawns ten threads, each of which do ten fork/waitpid
sequences. The cause of the problem was that when one of the fork
children exited before the corresponding fork parent could initiate its
waitpid for that child, a SIGCHLD and/or SIGSTOP was delivered and
interrupted a fork or waitpid in another thread.
The fix was to wrap the system calls in a loop to retry the call if
it was interrupted, like:
do
{
pid = fork ();
}
while (pid == -1 && errno == EINTR);
Since this is a Linux-only test I figure it is OK to use errno and EINTR.
I tried a number of alternative fixes using SIG_IGN, SA_RESTART,
pthread_sigblock, and bsd_signal, but none of these worked as well.
Tested on Nios II Linux target with x86 Linux host.

PR 18303, Tolerate malformed input for lookup_symbol-called functions
lookup_symbol is often called with user input. Consequently, any
function called from lookup_symbol{,_in_language} should attempt to
deal with malformed input gracefully. After all, malformed user
input is not a programming/API error.
This patch does not attempt to find/correct all instances of this. It
only fixes locations in the code that trigger test suite failures.
This patch fixes PR breakpoints/18303, "Assertion: -breakpoint-insert
with windows paths of file in non-current directory".
The patch includes three new tests related to this. One is just
gdb.linespec/ls-errs.exp copied and converted to use C++ instead of C, and
to add a case using a file name containing a Windows-style logical drive
specifier. The others include an MI test to provide a regression test for
the specific case reported in PR 18303, and a C++ test for proper error
handling of access to a program variable when using a file scope specifier
that refers to a non-existent file.
Tested on x86_64 native Linux.

Add -z noreloc-overflow option to x86-64 ld
Add -z noreloc-overflow command-line option to the x86-64 ELF linker to

Fix PR gdb/19676: Internal error in linux-thread.db.c if /proc not mounted
If /proc is not mounted, GDB fails an assertion in find_new_threads_once:
Continuing.
.../src/gdb/linux-thread-db.c:1249: internal-error: find_new_threads_once: Assertion `!target_has_execution' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
That was supposed to catch misuses of td_ta_thr_iter, which is unsafe
for live debugging. However, if /proc is not mounted, we still
fallback to using it.
I didn't bother with a warning, because GDB already prints several
others related to failing to open /proc files.

Fix PR gdb/19676: Disable displaced stepping if /proc not mounted
On GNU/Linux archs that support displaced stepping, if /proc is not
mounted, GDB gets stuck not able to step past breakpoints:
(gdb) c
Continuing.
dl_main (phdr=<optimized out>, phnum=<optimized out>, user_entry=<optimized out>, auxv=<optimized out>) at rtld.c:2163

Cannot find AT_ENTRY auxiliary vector entry.

That's because GDB can't figure out where the scratch pad is.
This is a regression introduced by the earlier changes to make the
Linux native target always work in non-stop mode.
This commit makes GDB detect the case and fallback to stepping over
breakpoints in-line.

Add $_as_string convenience function
This patch is a follow-up to "Add printf format specifier for printing
enumerator":
https://sourceware.org/ml/gdb-patches/2016-02/msg00144.html
Instead of having a solution specific to the printf command, Pedro
suggested adding a general purpose function $_as_string() that would
cover this use case and more.
So, in order to print the textual label of an enum, one can use:
(gdb) printf "Visiting node of type %s\n", $_as_string(node)
Visiting node of type NODE_INTEGER

Command line input handling TLC
I didn't manage to usefully split this further into smaller
independent pieces, so:
- Use "struct buffer" more.
- Split out the responsibility of composing a complete command line
from multiple input lines split with backslash
(
E.g.:
(gdb) print \
1 + \
2
$1 = 3
(gdb)
)
to a separate function. Note we don't need the separate
readline_input_state and more_to_come globals at all. They were
just obfuscating the logic.
- Factor out the tricky mostly duplicated code in
command_line_handler and command_line_input.

the local entry. Fix by calling the function via a pointer in a global

S390: Recognize special jumps in prologue parser
Functions compiled with the gcc option `-mhotpatch' may start with a
branch-never BRCL instruction as a 6-byte NOP. And functions compiled
with `-mstack-size' contain a BRC instruction in their prologue that is
actually a conditional trap. Both of these special jumps cause the
prologue parser to stop and yield bad unwinding results.
This change makes the prologue analyzer recognize such special jumps and
ignore them.

* s390-linux-tdep.c (s390_analyze_prologue): Ignore BRC and BRCL
instructions that do nothing or are conditional traps.

S390: Add use of unavailable-stack frame ID
When determining the frame ID of an inline frame, GDB currently asserts
that a valid ID of the underlying real frame is found, and that it does
not match outer_frame_id. From inline_frame_this_id():
/* For now, require we don't match outer_frame_id either (see
comment above). */
gdb_assert (!frame_id_eq (*this_id, outer_frame_id));
However, this assertion may fail when the real frame's unwinder can not
determine the frame ID. This happened on an s390x target with a binary
that lacked call frame information and also confused the prologue
analyzer, because then s390_frame_this_id() left the frame ID at its
default.
To fix this, this change enhances s390_frame_this_id such that an
unavailable-stack frame ID is built if no frame base can be determined
but the function address is available.
gdb/ChangeLog:
* s390-linux-tdep.c (s390_prologue_frame_unwind_cache): Store
frame func's PC in info->func before any other failure can occur.
(s390_frame_this_id): Use frame_id_build_unavailable_stack if
info->func has been filled out.

Avoid spaces in osabi names
It's not possible today to select some of the osabis by name.
Specifically, those that have spaces in their names and then the first
word is ambiguous...
For example:
(gdb) set osabi <TAB>
[...]
FreeBSD ELF
FreeBSD a.out
[...]
(gdb) set osabi FreeBSD ELF
Ambiguous item "FreeBSD ELF".
In reality, because "set osabi" is an enum command, that was
equivalent to trying "set osabi FreeBSD", which is then obviously
ambiguous, because of "FreeBSD ELF" and "FreeBSD a.out".
Also, even if the first word is not ambiguous, we actually ignore
whatever comes after the first word:
(gdb) set osabi GNU/Linux
(gdb) show osabi
The current OS ABI is "GNU/Linux".
The default OS ABI is "GNU/Linux".
(gdb) set osabi Windows SomeNonsense
^^^^^^^^^^^^
(gdb) show osabi
The current OS ABI is "Windows CE".
The default OS ABI is "GNU/Linux".
(gdb)
Fix this by avoiding spaces in osabi names.
We could instead make "set osabi" have a custom set hook, or
alternatively make the enum set hook (in cli-setshow.c) handle values
with spaces, but OTOH, I have a feeling that could cause trouble.
E.g., in cases where we might want to write more than one enum value
in the same line. We could support quoting as workaround, but, not
sure we want that. "No spaces" seems like a simpler rule.

[FR-V] Handle FR300
Even though "set architecture" presents fr300 as option:
(gdb) set architecture fr<TAB>
fr300 fr400 fr450 fr500 fr550 frv
Actually selecting fr300 doesn't work:
(gdb) set architecture fr300
Architecture `fr300' not recognized.
The target architecture is set automatically (currently i386)
(gdb)
This just looks like an obvious oversight. Looking around gcc and
binutils sources, FR300 is basically a FR500 specialized for DSP and
low power.

Fix v850 bfd arch info printable names
Currently, it's not possible to manually set some of the v850 archs in
gdb:
(gdb) set architecture v850<TAB>
v850 (using old gcc ABI)
v850-rh850
v850e
v850e (using old gcc ABI)
v850e1
[...]
(gdb) set architecture v850 (using old gcc ABI)
Ambiguous item "v850 (using old gcc ABI)".
The problem is that "set architecture" is a GDB "enum command", and
GDB only considers an enum value to be the string up until the first
space. So writing "v850 (using old gcc ABI)" is the same as writing
"v850", and then that's not an unambiguous arch printable name prefix.
v850 is actually the only arch that has spaces in its printable name.
One can conveniently see that with e.g.:
(gdb) set max-completions unlimited
(gdb) complete set architecture
...
Rather than hack GDB into accepting this somehow, make v850 arch
printable names more like the printable names of the other archs, and
put the abi variant in the "machine" part, after a ':'.
We now get:
(gdb) set architecture v850<TAB>
v850:old-gcc-abi
v850:rh850
v850e
v850e1
v850e1:old-gcc-abi
v850e2
v850e2:old-gcc-abi
[...]
And now "set architecture v850:old-gcc-abi" works as expected.
I ran the binutils/gas/ld testsuites, and found no regressions. I
don't have a cross compiler handy, but I ran the gdb tests anyway,
which covers at least some snoke testing.
I think that the OUTPUT_ARCH in ld/scripttempl/v850.sc may have got
broken with the previous 2012 change, since I hacked v850_rh850.sc to
output "v850" and ld failed to grok it. I think it only works if the
old GCC ABI is the configured v850 default ABI. That's now fixed by
changing to use explicit v850:old-gcc-abi.
Also, this actually "fixes" an existing GDB test, which isn't likewise
expecting spaces in arch names, when GDB is configured for
--target=v850:
(gdb) FAIL: gdb.xml/tdesc-arch.exp: read valid architectures

type = long double
(gdb)
Even if the target and host floating-point formats match, the length
of the types might still be different. On x86, long double is the
80-bit extended precision type on both 32-bit and 64-bit ABIs, but by
default it is stored as 12 bytes on 32-bit, and 16 bytes on 64-bit,
for alignment reasons. Several places in doublest.c already consider
this, but floatformat_to_doublest and floatformat_from_doublest miss
it. E.g., convert_typed_floating and store_typed_floating,

Fix HP/PA GNU/Linux "long double" format
This:
$ ./gdb -ex "set architecture hppa1.0" -ex "set osabi GNU/Linux" -ex "ptype 1.0L"
Shows that HPPA/Linux support for long doubles is broken. It causes
GDB to access memory out of bounds. With Valgrind, we see:
The target architecture is assumed to be hppa1.0

The trouble is that hppa_linux_init_abi overrides the default
long_double_bit set by the generic hppa-tdep.c:
set_gdbarch_long_double_bit (gdbarch, 128);
set_gdbarch_long_double_format (gdbarch, floatformats_ia64_quad);
with:
/* On hppa-linux, currently, sizeof(long double) == 8. There has been
some discussions to support 128-bit long double, but it requires some
more work in gcc and glibc first. */
set_gdbarch_long_double_bit (gdbarch, 64);
which misses overriding the long_double_format, so we end with a weird
combination of:
set_gdbarch_long_double_bit (gdbarch, 64);
set_gdbarch_long_double_format (gdbarch, floatformats_ia64_quad);
Weird because floatformats_ia64_quad's totalsize is longer than 64-bits.
The floatformat conversion routines use the struct floatformat's
totalsize (in bits) to know how much to copy/convert, thus the buffer
overruns.

Refactor Output_data_reloc_base::do_write for MIPS-specific relocs.
This patch is a simple refactoring that will allow the MIPS backend to
replace the Output_data_reloc_base::do_write() method without copying
its entire implementation. I've moved the implementation of do_write()
into a function template, which can be instantiated with a custom
class to write the MIPS-specific relocation format. The custom class
for MIPS needs access to the symbol index and address from
Output_reloc, so I've included the part of Vlad's MIPS-64 patch that
makes those accessor methods public.

Improve analysis of racy testcases
This is an initial attempt to introduce some mechanisms to identify
racy testcases present in our testsuite. As can be seen in previous
discussions, racy tests are really bothersome and cause our BuildBot
to pollute the gdb-testers mailing list with hundreds of
false-positives messages every month. Hopefully, identifying these
racy tests in advance (and automatically) will contribute to the
reduction of noise traffic to gdb-testers, maybe to the point where we
will be able to send the failure messages directly to the authors of
the commits.
I spent some time trying to decide the best way to tackle this
problem, and decided that there is no silver bullet. Racy tests are
tricky and it is difficult to catch them, so the best solution I could
find (for now?) is to run our testsuite a number of times in a row,
and then compare the results (i.e., the gdb.sum files generated during
each run). The more times you run the tests, the more racy tests you
are likely to detect (at the expense of waiting longer and longer).
You can also run the tests in parallel, which makes things faster (and
contribute to catching more racy tests, because your machine will have
less resources for each test and some of them are likely to fail when
this happens). I did some tests in my machine (8-core i7, 16GB RAM),
and running the whole GDB testsuite 5 times using -j6 took 23 minutes.
Not bad.
In order to run the racy test machinery, you need to specify the
RACY_ITER environment variable. You will assign a number to this
variable, which represents the number of times you want to run the
tests. So, for example, if you want to run the whole testsuite 3
times in parallel (using 2 cores), you will do:
make check RACY_ITER=3 -j2
It is also possible to use the TESTS variable and specify which tests
you want to run:
make check TEST='gdb.base/default.exp' RACY_ITER=3 -j2
And so on. The output files will be put at the directory
gdb/testsuite/racy_outputs/.
After make invokes the necessary rules to run the tests, it finally
runs a Python script that will analyze the resulting gdb.sum files.
This Python script will read each file, and construct a series of sets
based on the results of the tests (one set for FAIL's, one for
PASS'es, one for KFAIL's, etc.). It will then do some set operations
and come up with a list of unique, sorted testcases that are racy.
The algorithm behind this is:
for state in PASS, FAIL, XFAIL, XPASS...; do
if a test's state in every sumfile is $state; then
it is not racy
else
it is racy
(The algorithm is actually a bit more complex than that, because it
takes into account other things in order to decide whether the test
should be ignored or not).
IOW, a test must have the same state in every sumfile.
After processing everything, the script prints the racy tests it could
identify on stdout. I am redirecting this to a file named racy.sum.
Something else that I wasn't sure how to deal with was non-unique
messages in our testsuite. I decided to do the same thing I do in our
BuildBot: include a unique identifier in the end of message, like:
gdb.base/xyz.exp: non-unique message
gdb.base/xyz.exp: non-unique message <<2>>
This means that you will have to be careful about them when you use
the racy.sum file.
I ran the script several times here, and it did a good job catching
some well-known racy tests. Overall, I am satisfied with this
approach and I think it will be helpful to have it upstream'ed. I
also intend to extend our BuildBot and create new, specialized
builders that will be responsible for detecting the racy tests every X
number of days.

Fix argument passing for call
When calling function with argument of size more than 8 bytes fails with
an error "That operation is not available on integers of more than 8 bytes.".
avr-gdb considers only 8 bytes (sizeof(long long)) in case of passing the
argument in registers. When the argument is of size more than 8 byte
then the utility function to extract bytes failed with the above error.

* avr-tdep.c (AVR_LAST_ARG_REGNUM): Define.
(avr_push_dummy_call): Correct last needed argument register.
Write MSB of argument into register and subsequent bytes into
other registers in decreasing order.

ARM process record: VMOV
ARM process record gets the wrong register number for VMOV (from core
register to single-precision register). That is, we should record
the D register rather than the S pseudo register. The patch also
removes the condition "bit (arm_insn_r->arm_insn, 20)" check, which
has been checked above.
It fixes the following internal error,

Step over fork/vfork syscall insn in gdbserver
We can also extend disp-step-syscall.exp to test GDBserver step over
breakpoint on syscall instruction. That is, we set a breakpoint
with a false condition on syscall instruction, so that GDBserver will
step over it.
This test triggers a GDBserver internal error, which can be fixed by
this series.

Step over syscalll insn with disp-step on and off
disp-step-syscall.exp was added to test displaced stepping over syscall
instructions, in which we set breakpoint on syscall instruction, and
step over it. In fact, we can extend the test to non-displaced-stepping

when GDBserver steps over a thread, other threads have been suspended,
the "stepping" thread may create new thread, but GDBserver doesn't set
it suspend count to 1. When GDBserver unsuspend threads, the child's
suspend count goes to -1, and the assert is triggered. In fact, GDBserver
has already taken care of suspend count of new thread when GDBserver is
suspending all threads except the one GDBserver wants to step over by
https://sourceware.org/ml/gdb-patches/2015-07/msg00946.html
+ /* If we're suspending all threads, leave this one suspended
+ too. */
+ if (stopping_threads == STOPPING_AND_SUSPENDING_THREADS)
+ {
+ if (debug_threads)
+ debug_printf ("HEW: leaving child suspended\n");
+ child_lwp->suspended = 1;
+ }
but that is not enough, because new thread is still can be spawned in
the thread which is being stepped over. This patch extends the
condition that GDBserver set child's suspend count to one if it is
suspending threads or stepping over the thread.

Don't recursively look for a symbol in all imports of imported modules.
Given two or more modules that import each other's scope, the current symbol
lookup routines would go round in circles looking through each import from
each module, possibly checking the same module twice or more until all possible
paths are marked as "searched".
Given enough modules, this causes an exponential slowdown in time taken to find
symbols that do exist, and infinite recursion when they don't.

cyclic imports.

[BFD][AARCH64]Fix MOVW_SABS_G(0,1,2) relocation overflow check.
For these three relocations, 17 bit signed value should be used, instead of
16 bit. The bitsize field is changed from 16 to 17, this field in aarch64
backend is used for overflow check only.

Optimize x86 GOT32X/GOTPCRELX relocations
R_386_GOT32X, R_X86_64_GOTPCRELX and R_X86_64_REX_GOTPCRELX relocations
retrieve the symbol address via its GOT slot. If the symbol address is
known at the link-time, we can use it directly by changing instruction
encoding. Indirect branch can only be converted to PC relative direct
branch. MOV can be changed to LEA or encoded differently with signed
address. The subset of binary operations can be encoded only with
signed address.
If undefined weak symbol is resolved to zero link-time, we can use it
as address. Zero addresss can't used with PC relative direct branch
when PIC is true since the current PC is unknown. In 64-bit, 32-bit
relocation for PC relatiave direct branch to zero may also overflow.
If this optimization causes relocation overflow, --no-relax can be used
to work around it.

gdb.reverse/insn-reverse.c to test more arm instructions.
- Set flag SINGLE_REG correctly. In the arch reference manual,
SING_REG is true when the bit 8 of instruction is zero.
- Record the right D registers for instructions changing S registers.
- Fix the order of length and address in record_buf_mem array.
- Shift the offset by 2 instead of by 24.

Properly implement STT_COMMON
The BFD configure option, --enable-elf-stt-common, can't be to used to
verify STT_COMMON implementation with the normal binutils build. Instead,
this patch removes it from BFD. It adds --elf-stt-common=[no|yes] to ELF
assembler/objcopy and adds -z common/-z nocommon to ld.
A configure option, --enable-elf-stt-common, is added to gas to specify
whether ELF assembler should generate common symbols with the STT_COMMON
type by default.
Since BSF_KEEP_G is never used, it is renamed to BSF_ELF_COMMON for ELF
common symbols.

[x86] Resolve non-PIC undefweak symbols in executable
For i386 and x86-64, non-PIC references to undefined weak symbols are
resolved without dynamic relocation when creating executable. Resolved
undefined weak symbols are removed from the dynamic symbol table in
executable. One exception is on i386, we need resolved undefined weak
symbols in the dynamic symbol table in PIE if input relocatable files
contain branchs without PLT so that we can branch to 0 with dynamic
relocation in text section.
This makes behaviors of dynamic executable and position independent
executable predictable with mixed PIC and non-PIC references to undefined
weak symbols. If all references to undefined weak symbols are PIC,
dynamic relocations against undefined weak symbols will be generated
in executable unless -z nodynamic-undefined-weak is passed to linker.

gdbserver/s390: Enable high GPRs, VX, TDB with 31-bit gdbserver.
Currently, 31-bit gdbserver doesn't support collecting/supplying high
GPRs, VX registers, and TDB data. This is not much of a problem now,
since machines that have them usually have a 64-bit gdbserver that can
be used to debug 31-bit targets just fine. However, with fast
tracepoints, it's not possible to use a 64-bit gdbserver with a 31-bit
IPA (and thus a 31-bit target), so 31-bit gdbserver has to be used
for 31-bit targets. Thus, this patch is needed to allow collecting
high GPRs and VX registers on 31-bit targets via fast tracepoints.

* linux-s390-low.c (s390_num_regs_3264): Define on 31-bit too.

[PR gdb/13808] gdb.trace: Pass tdesc selected in gdbserver to IPA.
If gdbserver and IPA are using different tdesc, they will disagree
about 'R' trace packet size. This results in mangled traces.
To make sure they pick the same tdesc, gdbserver pokes the tdesc
(specified as an index in a target-specific list) into a global
variable in IPA. In theory, IPA could find out the tdesc on its
own, but that may be complex (in particular, I don't know how to
tell whether we have LAST_BREAK on s390 without messing with ptrace),
and we'd have to duplicate the logic.
Tested on i386 and x86_64. On i386, it fixes two FAILs in ftrace.exp.
On x86_64, these failures have been KFAILed - one of them works now,
but the other now fails due to an unrelated reason (ugh).

gdb.trace: Surround $call_insn with \y in entry-values.exp
The PPC64 tracepoint patch added \y at the end of the call_insn pattern -
without that, it embarassed itself and matched the 'bl' in "Dump of
assem*bl*er code for function" as the powerpc call opcode. Since that
sounds like a generally good idea, I've added \y before and after
call_insn for every target. As a result, I had to change x86_64's mnemonic
to 'callq'.
gdb/testsuite/ChangeLog:
* gdb.trace/entry-values.exp: Surround $call_insn with '\y',
change x86_64 call_insn to 'callq'.

Map registers to remote numbers when encoding an ax_reg or ax_reg_mask operation
When encoding the agent expression operation ax_reg or ax_reg_mask, the
register number used is internal to GDB. However GDBServer expects a tdesc
based number.
This usually does not cause a problem since at the moment, for raw
registers GDBServer R trace action ignores the register mask and just
collects all registers.
It can be a problem, however with pseudo registers on some platforms if the
tdesc number doesn't match the GDB internal register number.
This is the case with ARM, the upcoming ARM tracepoint support, fails
these test cases without this patch:
gdb.trace/collection.exp: collect register locals collectively:*
GDBSever would exit with: unhandled register size
Since the register number is not mapped.
This patch fixes these issues by calling gdbarch_remote_register_number
before encoding the register number in the ax_reg or ax_reg_mask operation.
Tested on x86 native-gdbserver no regressions observed.
gdb/ChangeLog:
* ax-general.c (ax_reg): Call gdbarch_remote_register_number.
(ax_reg_mask): Likewise.

Handle MIPS Linux SIGTRAP siginfo.si_code values
This unbreaks pending/delayed breakpoints handling, as well as
hardware watchpoints, on MIPS.
Ref: https://sourceware.org/ml/gdb-patches/2016-02/msg00681.html
The MIPS kernel reports SI_KERNEL for all kernel generated traps,
instead of TRAP_BRKPT / TRAP_HWBKPT, but GDB isn't aware of this.
Basically, this commit:
- Folds watchpoints logic into check_stopped_by_breakpoint, and
renames it to save_stop_reason.
- Adds GDB_ARCH_IS_TRAP_HWBKPT.
- Makes MIPS set both GDB_ARCH_IS_TRAP_BRPT and
GDB_ARCH_IS_TRAP_HWBKPT to SI_KERNEL. In save_stop_reason, we
handle the case of the same si_code returning true for both
TRAP_BRPT and TRAP_HWBKPT by looking at what the debug registers
say.
Tested on x86-64 Fedora 20, native and gdbserver.

Process record for aarch64-linux syscall
This patch updates the syscalls in sync with syscalls/aarch64-linux.xml.
Some syscalls are still not supported by gdb/linux-record.c yet. Mark
them UNSUPPORTED_SYSCALL_MAP.
This patch fixes the following test fail,
Process record and replay target doesn't support syscall number 56^M
Process record: failed to record execution log.^M
^M
Program stopped.^M

gdb.trace: Fix unavailable.exp if last register happens to be PC.
unavailable.exp executes "info registers", expecting to find at least
two instances of "<unavailable>". However, it uses
"<unavailable>.*<unavailable>" as the pattern, which doesn't match
when the last register happens to be available (eg. PC). Change it
to ".*<unavailable>.*<unavailable>.*" instead.
Noticed on s390, no regression on x86_64.

Intel MPX bound violation handling
With Intel Memory Protection Extensions it was introduced the concept of
boundary violation. A boundary violations is presented to the inferior as
a segmentation fault having SIGCODE 3. This patch adds a
handler for a boundary violation extending the information displayed
when a bound violation is presented to the inferior. In the stop mode
case the debugger will also display the kind of violation: "upper" or
"lower", bounds and the address accessed.
On no stop mode the information will still remain unchanged. Additional
information about bound violations are not meaningful in that case user
does not know the line in which violation occurred as well.
When the segmentation fault handler is stop mode the out puts will be
changed as exemplified below.
The usual output of a segfault is:
Program received signal SIGSEGV, Segmentation fault
0x0000000000400d7c in upper (p=0x603010, a=0x603030, b=0x603050,
c=0x603070, d=0x603090, len=7) at i386-mpx-sigsegv.c:68
68 value = *(p + len);
In case it is a bound violation it will be presented as:
Program received signal SIGSEGV, Segmentation fault
Upper bound violation while accessing address 0x7fffffffc3b3
Bounds: [lower = 0x7fffffffc390, upper = 0x7fffffffc3a3]
0x0000000000400d7c in upper (p=0x603010, a=0x603030, b=0x603050,
c=0x603070, d=0x603090, len=7) at i386-mpx-sigsegv.c:68
68 value = *(p + len);
In mi mode the output of a segfault is:
*stopped,reason="signal-received",signal-name="SIGSEGV",
signal-meaning="Segmentation fault", frame={addr="0x0000000000400d7c",
func="upper",args=[{name="p", value="0x603010"},{name="a",value="0x603030"}

gdb: Add guess_tracepoint_registers hook to gdbarch.
When we're looking at a tracefile trace frame where registers are not
available, and the tracepoint has only one location, we supply
the location's address as the PC register. However, this only works
if PC is not a pseudo register, and individual architectures may want
to guess more registers. Add a gdbarch hook that will handle that.

xtensa: fix .init/.fini literals moving
Despite the documentation and the comment in xtensa_move_literals, in
the presence of --text-section-literals and --auto-litpools literals are
moved from the separate literal sections into .init and .fini, because
the check in the xtensa_move_literals is incorrect.
This moving was broken with introduction of auto litpools: some literals
now may be lost. This happens because literal frags emitted from .init
and .fini are not closed when new .literal_position marks new literal
pool. Then frag_align(2, 0, 0) changes type of the last literal frag to
rs_align. rs_align frags are skipped in the xtensa_move_literals. As a
result fixups against such literals are not moved out of .init.literal/
.fini.literal sections producing the following assembler error:
test.S: Warning: fixes not all moved from .init.literal
test.S: Internal error!
Fix check for .init.literal/.fini.literal in the xtensa_move_literals
and don't let it move literals from there in the presence of
--text-section-literals or --auto-litpools.

PR remote/19496, internal err forking-threads-plus-bkpt
This patch fixes an internal error that occurs in
gdb.threads/forking-threads-plus-breakpoint.exp:
/blah/binutils-gdb/gdb/target.c:2723: internal-error: Can't determine the
current address space of thread Thread 3170.3170
In default_thread_address_space, find_inferior_ptid couldn't find 3170.3170
because it had been overwritten in inferior_appeared, called as follows:
inferior_appeared
remote_add_inferior
remote_notice_new_inferior
remote_update_thread_list
The cause of the problem was the following sequence of events:
* GDB knows only about the main thread
* the first fork event is reported to GDB, saved as pending_event
* qXfer:threads:read gets the threads from the remote.
remove_new_fork_children id's the fork child from the pending event
and removes it from the list reported to GDB. All the rest of the
threads, including the fork parent, are added to the GDB thread list.
* GDB stops all the threads. All the stop events are pushed onto the
stop reply queue behind the pending fork event. The fork waitstatus
is saved in the fork parent thread's pending status field
thread_info.suspend.
* remote_wait_ns calls queued_stop_reply and process_stop_reply to
remove the fork event from the front of the stop reply queue and save
event information in the thread_info structure for the fork parent
thread. Unfortunately, none of the information saved in this way is
the fork-specific information.
* A subsequent qXfer:threads:read packet gets the thread list including
the fork parent and fork child. remove_new_fork_children checks the
thread list to see if there is a fork parent, doesn't find one, checks
the stop reply queue for a pending fork event, doesn't find one, and
allows the fork child thread to be reported to GDB before the fork
event has been handled. remote_update_thread_list calls
remote_notice_new_thread and overwrites the current (main) thread in
inferior_appeared.
So the fork event has been reported out of target_wait but it was left
pending on the infrun side (infrun.c:save_waitstatus). IOW, the fork
event hasn't been processed by handle_inferior_event yet, so it hasn't
made it to tp->pending_follow yet.
The fix is to check thread_info.suspend along with the
thread_info.pending_follow in remote.c:remove_new_fork_children, to
prevent premature reporting of the fork child thread creation.

testsuite: Make standard_temp_file use invocation-specific directories
Just like standard_output_file, standard_temp_file should use multiple
directories to make the tests parallel-safe. However,
standard_temp_file is sometimes called in some procedures that are not
test-specific. For example, gdb_init uses it, but is called once before
all test files are ran. Therefore, we can't organize it in a
temp/gdb.subdir/testname layout, like standard_output_file.
Because it's just meant for temporary files that don't really need to be
inspected after the test, we can just put them in a directory based on
the runtest pid. There is always a single exp file being executed by a
particular runtest invocation at any given time, so it should be safe.
gdb/testsuite/ChangeLog:
* lib/gdb.exp (standard_temp_file): Return a path specific to
the runtest invocation.

testsuite: Fix save-trace.exp writing outside standard output directory
In save-trace.exp, we want to test loading of a tracepoint definition
file with a relative path (I am not sure why in fact). We currently use
"savetrace-relative.tr", which ends up directly in testsuite/. If we
use [standard_output_file] on that path, it becomes absolute. I decided
to just replace [pwd] with . (a dot) in the path given by
standard_output_file to make it relative. However, this trick only
works because [pwd] is a prefix of the standard output directory. So I
added a check to verify that precondition.
gdb/testsuite/ChangeLog:
* gdb.trace/save-trace.exp: Change relative path to be in the
standard output directory.

Fix BFD format matching for x86_64-w64-mingw32 -m32 LTO.
In <https://sourceware.org/ml/binutils/2015-12/msg00190.html> (commit
4a07dc81356ed8728e204e9aabeb256703c59aef), Kwok fixed a problem with
the template used for a dummy BFD for an IR file for LTO on MinGW,
where the input and output formats are not the same.
A problem, however, remains in the case of linking for
x86_64-w64-mingw32 -m32, where LTO linking reports an ambiguity
between the pe-i386 and pei-i386 formats. An object (pe-i386) with
plugin data is being tested by the linker to see what formats match.
The default format initially set by the linker when
bfd_check_format_matches is called is pei-i386 (as that's the output
format from the linker script), which does not match, so the function
goes on to the loop over possible BFD vectors. The pe-i386 vector
matches, as it should. One other vector matches: the plugin vector.
bfd_check_format_matches tests a vector for matching by temporarily
modifying the BFD object to use that vector then using
_bfd_check_format on it. So the BFD object is temporarily using
plugin_vec. _bfd_check_format ends up using bfd_plugin_object_p which
uses plugin_object_p from ld which uses plugin_get_ir_dummy_bfd which
succeeds, having created a BFD based on link_info.output_bfd (because
srctemplate is the BFD temporarily using plugin_vec, even after Kwok's
patch link_info.output_bfd is all that's available to base the dummy
BFD on). So we end up with a match from the plugin vector which uses
the pei-i386 vector even though the pei-i386 vector itself does not
match the input object. (In the i686-mingw32 case, as opposed to this
multilib case, pe-i386 is the default BFD target, which would
short-circuit that logic.)
There are two cases of the linker handling inputs with a plugin: they
may be inputs that are also accepted by some non-plugin BFD format, as
here, or they may be a format that would not be recognized at all, as
with some tests in the ld testsuite. In the former case, there is no
need for BFD to accept the objects using the plugin vector, as the
linker has its own logic to allow plugins to claim objects accepted by
some other BFD vector. Thus, this patch arranges for the plugin
vector to have the lowest match priority, and for the priority from
that vector to be used in the relevant case (the attempted match to
the plugin vector results in TEMP pointing to the pei-i386 vector).
Tested for GCC and Binutils testsuites for x86_64-pc-linux-gnu, as
well as verifying that it fixes the observed LTO issue for
x86_64-w64-mingw32.
* plugin.c (plugin_vec): Set match priority to 255.
* format.c (bfd_check_format_matches) [BFD_SUPPORTS_PLUGINS]: When
matching against the plugin vector, take priority from there not
from TEMP.

[ARM] Software single step cross kernel helpers
GDB step cross kernel helpers only works if the kernel helpers are tail
called, which is the case how it is used in glibc. See __aeabi_read_tp
in sysdeps/unix/sysv/linux/arm/aeabi_read_tp.S. In __aeabi_read_tp,
branch/jump to the kernel helper is the last instruction, and the next
instruction address is in LR, which is in caller function. GDB can
handle this correctly. For example, glibc function __GI___ctype_init
calls __aeabi_read_tp
0xb6e19b30 <__GI___ctype_init+4>: ldr r3, [pc, #80] ;
0xb6e19b34 <__GI___ctype_init+8>: bl 0xb6e0a6e0 <__aeabi_read_tp>
0xb6e19b38 <__GI___ctype_init+12>: ldr r3, [pc, r3]
and __aeabi_read_tp calls kernel helper,
(gdb) disassemble __aeabi_read_tp
0xb6fef5d0 <+0>: mvn r0, #61440 ; 0xf000
0xb6fef5d4 <+4>: sub pc, r0, #31
once GDB or GDBserver single step instruction on 0xb6fef5d4, LR is
0xb6e19b38, which is right address of next instruction to set breakpoint
on.
However, if the kernel helpers are not tail-called, the LR is still the
address in the caller function of kernel helper's caller, which isn't
the right address of next instruction to set breakpoint on. For example,
we use kernel helper in main,
(gdb) disassemble main
....
0x00008624 <+32>: mov r3, #4064 ; 0xfe0^M
0x00008628 <+36>: movt r3, #65535 ; 0xffff^M
0x0000862c <+40>: blx r3
0x00008630 <+44>: ldr r3, [r11, #-8]
kernel helper is called on 0x0000862c and the expected next instruction
address is 0x00008630, but the LR now is the return address of main.
The problem here is LR may not have the right address because when we
single step the instruction, it isn't executed yet, so the LR isn't
updated. This patch fix this problem by decoding instruction, if the
instruction updates LR (BL and BLX), the next instruction address is
PC + INSN_SIZE, otherwise, get the address of next instruction from LR.

[ARM] Fixup PC in software single step
When I exercise GDBserver software single step, I see the following
error, which has been already handled by GDB properly.
In GDBserver log, we can see, GDBserver tries to single step instruction
on 0xb6e0a6e4, and destination address is 0xffff0fe0,
stop pc is 0xb6e0a6e4
Writing f001f0e7 to 0xffff0fe0 in process 7132
Failed to insert breakpoint at 0xffff0fe0 (Input/output error).
Failed to insert breakpoint at 0xffff0fe0 (-1).
(gdb) disassemble __aeabi_read_tp,+8
Dump of assembler code from 0xb6e0a6e0 to 0xb6e0a6e8:
0xb6e0a6e0 <__aeabi_read_tp+0>: mvn r0, #61440 ; 0xf000
0xb6e0a6e4 <__aeabi_read_tp+4>: sub pc, r0, #31
however, it fails inserting breakpoint there. This problem has already
fixed by GDB, see comments in arm-linux-tdep.c:arm_linux_software_single_step
/* The Linux kernel offers some user-mode helpers in a high page. We can
not read this page (as of 2.6.23), and even if we could then we
couldn't set breakpoints in it, and even if we could then the atomic
operations would fail when interrupted. They are all called as
functions and return to the address in LR, so step to there
instead. */
so we need to do the same thing in GDB side as well. This patch adds
a new field fixup in arm_get_next_pcs_ops, so that we can fix up PC
for arm-linux target. In this way, both GDB and GDBserver can single
step instructions going to kernel helpers.

btrace, frame: fix crash in get_frame_type
In skip_artificial_frames we repeatedly call get_prev_frame_always until we get
a non-inline and non-tailcall frame assuming that there must be such a frame
eventually.
For record targets, however, we may have a frame chain that consists only of
artificial frames. This leads to a crash in get_frame_type when dereferencing a
NULL frame pointer.
Change skip_artificial_frames and skip_tailcall_frames to return NULL in such a
case and modify each caller to cope with a NULL return.
In frame_unwind_caller_pc and frame_unwind_caller_arch, we simply assert that
the returned value is not NULL. Their caller was supposed to check
frame_unwind_caller_id before calling those functions.
In other cases, we thrown an error.
In infcmd further move the skip_tailcall_frames call to the forward-stepping
case since we don't need a frame for reverse execution and we don't want to fail
because of that. Reverse-finish does make sense for a tailcall frame.

gdbserver: Remove tracepoint_action ops.
This patch removes 'ops' in tracepoint, and uses helper functions to
call action handler instead.
The object layout of tracepoint_action may differ in gdbserver and
inferior depend on the alignment rule of target ABI, so gdbserver cannot
simply copy the object from its memory to inferior memory.
For example,
struct collect_memory_action
{
struct tracepoint_action base;
{
#ifndef IN_PROCESS_AGENT
const struct tracepoint_action_ops *ops;
#if
- char type;
| }
| ULONGEST addr;
| ULONGEST len;
- int32_t basereg;
};
and on PowerPC,
Wihtout ops with ops
0 1 2 3 0 1 2 3
0 |type| PADDING... 0 |ops-------------|
4 ................. 4 |type|PADDING....|
8 |addr------------ 8 |addr-------------
c ----------------| c -----------------|
10 |len------------- 10 |len--------------
14 ----------------| 14 -----------------|
18 |basereg--------| 18 |basereg---------|
so we cannot directly copy the object.
In this patch, 'ops' is removed in order to make the objects identical.

Support 'make check-parallel' in gdb's build dir
Currently, you can cd to the gdb/testsuite/ dir and use
make check-parallel, instead of using FORCE_PARALLEL:
$ make -j8 check-parallel RUNTESTFLAGS="--target_board=native-gdbserver"
$ make -j8 check RUNTESTFLAGS="--target_board=native-gdbserver" FORCE_PARALLEL=1
But you can't do that in the build/gdb/ dir:
$ make check-parallel RUNTESTFLAGS="--target_board=native-gdbserver"
make: *** No rule to make target `check-parallel'. Stop.
I find check-parallel a bit more convenient, and more typo-proof, so
this patch makes it work from the gdb build dir too.
While documenting this in testsuite/README, I found that the parallel
testing mode would better be pulled out to its own section and
extended.

- storing tdesc in tfile (without that, $ymm15 doesn't exist)
- ax_pseudo_register_collect for x86 (without that, $ymm15 cannot be
collected)
- register order in tfile_fetch_registers (without that, $ymm15h is
fetched from wrong position)
- off-by-one in tfile_fetch_registers (without that, $ymm15h is
incorrectly considered to be out of bounds)
- using proper tdesc in encoding tracepoint actions (without that,
internal error happens due to $ymm15h being considered unavailable)

Use the target architecture when encoding tracepoint actions
This patch uses the target architecture rather then the objfile
architecture when encoding tracepoint actions.
The target architecture may contain additional registers. E.g. ARM VFP
registers. This information is needed to allow their collection. Since we
can never know whether the registers numbers in the target match the
binary's we have to use tdesc here.
One note about combined debuggers / multi-inferior from Pedro Alves:
In the combined debugger case taking Cell as the practical example that
gdb supports currently:
In that case, the main target_gdbarch() will be powerpc, but you may have set a
tracepoint on _spu_ code, which has a different gdbarch. so for that case,
target_gdbarch would be wrong. I think that in that case, we'd need to
find __the_ target/tdesc gdbarch that is (bfd) compatible with the
objfile's gdbarch.
I think cell/spu gdbserver doesn't support tracepoints, so we can ignore
this for now.
The multi-inferior/process case is somewhat related, but its simpler.
each inferior has its own gdbarch.
That is, target_gdbarch depends on the current inferior selected.
In fact, that just returns inferior->gdbarch nowaways.
No regressions, tested on ubuntu 14.04 ARMv7 and x86.
With gdbserver-{native,extended} / { -marm -mthumb }

* tracepoint.c (encode_actions_1): Use target_gdbarch () rather

Clear *VAL in regcache_raw_read_unsigned
We have function regcache_raw_read_unsigned defined in both GDB and
GDBserver, so that it is used in common like this,
ULONGEST value;
status = regcache_raw_read_unsigned (regcache, regnum, &value);
'value' is correctly set in GDB side, but may not be correctly set
in GDBserver, because &value is passed in regcache_raw_read_unsigned
but collect_register may only set part of the whole variable. In my
test, I see the top half of 'value' is garbage. This patch fixes this
problem by clearing *VAL before calling collect_register.

breakpoints/19546: Fix crash after updating breakpoints
One of the last checks update_breakpoints_after_exec does while looping
over the list of breakpoints is check that the breakpoint has a valid
location spec. It uses event_location_empty_p to check if the location spec
is "empty", and if it is, the breakpoint is deleted.
momentary_breakpoint types rely on setting the breakpoint structure's
location spec to NULL, thereby causing an update to delete the breakpoint.
However, event_location_empty_p assumed that locations were never NULL.
As a result, GDB would crash dereferencing a NULL pointer whenever
update_breakpoints_after_exec would encounter a momentary_breakpoint.
This patch creates a new wrapper/helper function which tests that the given
breakpoint's location spec is non-NULL and if it is not "empty"
or "unspecified."

Enable/update legacy linespecs in MI.
MI is currently using string_to_event_location to enable the use of legacy
linespecs, but using this function (until this patchset) had the (as yet
unnoticed) side effect of allowing both MI and CLI representation for
explicit locations.
This patch simply changes MI to use the same legacy linespec functions
that the python and guile interpreters use. This eliminates the CLI syntax
for explicit locations (in MI).

Refactor string_to_event_location for legacy linespec support.
This patch refactors string_to_event_location, breaking it into two
separate functions:
1) string_to_event_location_basic
A "basic" string parser that implements support for "legacy" linespecs
(linespec, address, and probe locations). This function is intended to
be used by any UI wishing/needing to support this legacy behavior.
2) string_to_event_location
This is now intended as a CLI-only function which adds explicit location
parsing in a CLI-appropriate manner (in the form of traditional option/value
pairs).
Together these patches serve to simplify string-to-event location parsing
for all existing non-CLI interfaces (MI, guile, and python).

Fix PR19548: Breakpoint re-set inserts breakpoints when it shouldn't
PR19548 shows that we still have problems related to 13fd3ff34329:
[PR17431: following execs with "breakpoint always-inserted on"]
https://sourceware.org/ml/gdb-patches/2014-09/msg00733.html
The problem this time is that we currently update the global location
list and try to insert breakpoint locations after re-setting _each_
breakpoint in turn.
Say:
- We have _more_ than one breakpoint set. Let's assume 2.
- There's a breakpoint with a pre-exec address that ends up being an
unmapped address after the exec.
- That breakpoint is NOT the first in the breakpoint list.
Then when handling an exec, and we re-set the first breakpoint in the
breakpoint list, we mistakently try to install the old pre-exec /
un-re-set locations of the other breakpoint, which fails:
(gdb) continue
Continuing.

Always organize test artifacts in a directory hierarchy
When running tests in parallel, each test puts its generated files in a
different directory, under "outputs". I think it would be nice if it
was always the case, as it would isolate the test cases a bit more. An
artifact created by a test wouldn't get overwritten by another test.
Also, it makes it easier to clean up. A lot of executables are left all
over the place because their names do not appear in gdb.*/Makefile. If
everything is in "outputs", then we just have to delete that directory
(which we already do).
At the same time it makes the gdb.foo directories and their Makefiles
useless in the build directory, since they are pretty much only used for
cleaning.
What do you think?

Fix in-tree, parallel running of Ada tests
While testing the following patch,
[PATCH] Always organize test artifacts in a directory hierarchy
https://sourceware.org/ml/gdb-patches/2016-01/msg00133.html
I noticed that it broke Ada testing. This lead me to think that
parallel testing when building in-tree didn't work previously in Ada.
It is confirmed by this test:
$ make check TESTS="gdb.ada/fun_addr.exp" -j 2
...
Running ./gdb.ada/fun_addr.exp ...
FAIL: gdb.ada/fun_addr.exp: compilation foo.adb
...
This patch fixes in-tree parallel testing for Ada, and consequently
serial and parallel testing when the aforementioned patch is applied.
The problem originates from the fact that Ada support code cd's to the
builddir before compiling. In itself it's not a problem, it allows to
place intermediate auto-generated files in that directory. The Ada
compilation refers to the source file, which is in another directory,
only by its base name (e.g. foo.adb). In serial mode, that worked
because builddir was the same as the source directory (e.g.
gdb.ada/fun_addr/). In an out-of-tree build, it works because the
source directory is added as an include directory (note: this is not the
same $srcdir as autoconf's):
set srcdir [file dirname $source]
additional_flags=-I$srcdir
which becomes:
additional_flags=-I/home/emaisin/build/binutils-gdb/gdb/testsuite/gdb.ada/fun_addr
However, when building in-tree, srcdir is relative: ./gdb.ada/fun_addr.
When using parallel or always-in-outputs-directory mode, we are cd'ed in
the outputs directory. So -I$srcdir is relative to the current
directory, which is wrong.
To fix it, I made the TCL variable srcdir (set in site.exp, from which
everything else is derived) always absolute. It is done by assigning
autoconf's abs_srcdir instead of autoconf's srcdir. This way -I$srcdir
will always be good, regardless of where we cd'ed to. A small apparent
change is that when running tests, DejaGnu will say:
Running /tmp/binutils-gdb/gdb/testsuite/gdb.ada/fun_addr.exp ...
instead of
Running ./gdb.ada/fun_addr.exp ...
I hope it's not too much of an annoyance. I think that it should make
the testsuite a tiny bit more robust against other bugs of the same
class.
Regtested in & out of tree, only with native target.

* Makefile.in (abs_srcdir): Assign @abs_srcdir@.
(site.exp): Assign abs_srcdir to tcl's srcdir.

Fix incorrect x32 overflow checking for refs to weak undef symbols.
On x32, a pc-relative reference to an undef weak symbol (value 0)
with a negative addend (typically -4) generates a spurious overflow
error because Symbol_value::value() returns a 32-bit negative number
as an unsigned number, which gets zero-extended before subtracting
the PC value. This patch fixes the problem by special-casing the
negative addend, and adding it to the value after widening it to
64 bits. Symbol_value::value() does not need the addend if it's
negative, since it is only important when processing section
symbols for merge sections, where a positive addend provides the
input section offset of the merged constant.

varobj: Cleanup dead code
This patch removes some dead code.
I noticed that varobj_delete was always called with dellist == NULL, so
I started removing that parameter. That allows removing a good chunk of
the code in varobj_delete, making it almost trivial. We can also remove
the resultp parameters in that whole trail. In turn, this shows that
struct cpstack, cppush and cppop were only used fo that mechanism, so
they can be removed as well.
I also moved the function comment to the header file to comply with
today's guideline, even though the rest of the file does not respect it
(yet).

Fix compile errors about shift counts too large.
In order to get around the optimizer and newer compiler warnings
about shift counts, the overflow checking code had resorted to
some messy shifting, and with the never-before-seen instantiations
of the template functions, we were still running afoul of the
compiler checks.
This patch replaces those messy shift sequences with a simple
class template that provides the min and max limits for any
bit size up to 64, with a specialization for 64 that prevents
the compiler from complaining.

Fix overflow checking for 32-bit pc-relative relocations on x32.
The problem here is that x32 is really using 64-bit addressing,
while pretending to be 32-bit. Even though the object file format
is 32-bit, we need to do the overflow checking with 64-bit
arithmetic (because that's what the hardware will be using).
This patch overrides the pcrela32_check functions in reloc.h
with target-specific versions that do 64-bit checking.
I've also updated the test case to use -Tdata instead of adding
a huge .space directive, to reduce the size of the .o files.

[testsuite] Remove BASEDIR
BASEDIR was added by https://sourceware.org/ml/gdb-patches/2013-10/msg00587.html
in order to handle the different directory layout in serial testing
and parallel testing. BASEDIR is "gdb.base" in serial testing and is
"outputs/gdb.base/TESTNAME" in parallel testing. However, it doesn't
work if the GDBserver is in remote target, like this,
$ make check RUNTESTFLAGS='--target_board=remote-gdbserver-on-localhost foll-vfork.exp foll-exec.exp'
FAIL: gdb.base/foll-exec.exp: continue to first exec catchpoint (the program exited)
FAIL: gdb.base/foll-vfork.exp: exec: vfork and exec child follow, to main bp: continue to bp (the program exited)
FAIL: gdb.base/foll-vfork.exp: exec: vfork child follow, finish after tcatch vfork: finish (the program exited)
FAIL: gdb.base/foll-vfork.exp: exec: vfork relations in info inferiors: continue to bp (the program exited)
these tests fail because the executable can't be found. With target
board native-gdbserver, the program is spawned this way,
spawn ../gdbserver/gdbserver --once :2347 /scratch/yao/gdb/build-git/x86_64/gdb/testsuite/gdb.base/foll-vfork
so BASEDIR is correct. However, with target board
remote-gdbserver-on-localhost, the program is spawned
spawn /usr/bin/ssh -l yao localhost /scratch/yao/gdb/build-git/x86_64/gdb/testsuite/../gdbserver/gdbserver --once :2346 /scratch/yao/gdb/build-git/x86_64/gdb/testsuite/gdb.base/foll-vfork
so BASEDIR (either "gdb.base" or "outputs/gdb.base/TESTNAME") makes no
sense.
I had a fix that pass absolute directory to BASEDIR, but it assumes
that directory structure is the same on build and target, and it
doesn't work in remote host case. The current fix in this patch is
to get the directory from argv[0]. In any case, the program to be
exec'ed is at the same directory with the main program.
Note that these tests do "next N" to let program stop at the desired
line, but it is fragile, because GDB for different targets may skip
function prologue slightly differently, so I replace some of them by
"tbreak on LINE NUMBER and continue".

however, we did set rs->waiting_for_stop_reply to zero before Luis's
patch https://sourceware.org/ml/gdb-patches/2015-10/msg00336.html
In fact, Luis's patch v1
https://sourceware.org/ml/gdb-patches/2015-08/msg00809.html is about
setting rs->waiting_for_stop_reply back to one after
remote_fileio_request, which is correct. However during the review, the
patch is changed and ends up with "not setting rs->waiting_for_stop_reply
to zero".
I manually test GDB, but I don't have a way to run regression tests.

Add -mrelax-relocations= to x86 assembler
The x86 relax relocations introduced in binutils 2.26 aren't supported
by linker on Solaris older than Solaris 12. To use x86 assembler with
older Solaris linker, this patch adds
1. A command line option -mrelax-relocations= to x86 assembler to
control whether to generate relax relocations.
2. A configure option --enable-x86-relax-relocations to decide whether
x86 assembler should generate relax relocations by default. It is
defaulted to yes, except for x86 Solaris targets older than Solaris 12.

msp430: Set DWARF2_ADDR_SIZE to 4.
This change makes gas's notion of the msp430 dwarf2 address size match
that of gcc and gdb. This is needed so that the format of addresses
generated for DW_LNE_set_address in .debug_line will match the address
size for the compilation unit.
In gcc/config/msp430/msp430.h, it's set to 4:
#define DWARF2_ADDR_SIZE 4
Likewise in gdb/msp430-tdep.c:
set_gdbarch_dwarf2_addr_size (gdbarch, 4);
(As far as I can tell, however, GDB doesn't use this value when decoding
.debug_line. Instead, GDB uses the Pointer Size from the compilation
unit.)
readelf is able to seamlessly handle mismatches between these various
sizes by using the size of the DW_LNE_set_address instruction to
determine the address size. Another way to fix this problem is to
make GDB behave in a similar manner. In my opinion, GDB should detect
and inform the user about these mismatches; it's not clear to me if
it's correct for GDB to go ahead and read the address anyway when a
size mismatch is detected.
Without this change, addresses in .debug_line are encoded in two bytes
for some multilibs. When GDB reads the address for
DW_LNE_set_address, it uses the pointer size provided by the CU. When
these values don't match, GDB reads the wrong number of bytes. In the
cases that I've looked at, GDB is reading 4 bytes from a 2 byte
container, which results in a garbage address. GDB discards lines
which have a bogus address; the end result is that GDB records no line
number information for CUs which have a mismatch between the address
size (from the CU) and the format of the address used by
DW_LNE_set_address.

Store estimated istrances in compressed_size
elf_x86_64_convert_load is very time consuming since it is called on
each input section and has a loop over input text sections to estimate
the branch distrance. We can store the estimated distrances in the
compressed_size field of the output section, which is only used to
decompress the compressed input section.
Before the patch, linking clang 3.9 takes 52 seconds. After the patch,
it only takes 2.5 seconds.

opcodes/cgen: Rework calculation of shift when inserting fields
The calculation of the shift amount, used to insert fields into the
instruction buffer, is not correct when the following conditions are all
true:
- CGEN_INT_INSN_P is defined, and true.
- CGEN_INSN_LSB0_P is true
- Total instruction length is greater than the length of a single
instruction word (the instruction is made of multiple words)
- The word offset is non-zero (the field is outside the first word)
When the above conditions are all true, the calculated shift fails to
take account of the total instruction length.
After this commit the calculation of the shift amount is split into two
parts, first we calculate the shift required to get to BIT0 of the word
in which the field lives, then we calculate the shift required to place
the field within the instruction word.
The change in this commit only effects the CGEN_INT_INSN_P defined true
case, but changes the code for both CGEN_INSN_LSB0_P true, and false.
In the case of CGEN_INSN_LSB0_P being false, the code used to say:
shift = total_length - (word_offset + start + length);
Now it says:
shift_to_word = total_length - (word_offset + word_length);
shift_within_word = word_length - start - length;
shift = shift_to_word + shift_within_word;
From which we can see that in all cases the computed shift value should
be unchanged.
In the case of CGEN_INSN_LSB0_P being true, the code used to say:
shift = (word_offset + start + 1) - length;
Now it says:
shift_to_word = total_length - (word_offset + word_length);
shift_within_word = start + 1 - length;
shift = shift_to_word + shift_within_word;
In the case where 'total_length == word_length' AND 'word_offset ==
0' (which indicates an instruction of a single word), we see that the
computed shift value will be unchanged. However, when the total_length
and word_length are different, and the word_offset is non-zero then the
computed shift value will be different (and correct).

epiphany/gas: Update expected test results for 0 offset loads
In commit 02a79b89fdeadccb67048291e6c2a1e5ce6ad623 some of the load
instructions with a zero offset (where the offset is not mentioned) were
marked as NO-DIS, meaning that the disassembler must display the offset,
even though it is zero.
This change seems a little strange to me as it was only applied to some
loads, not all, and the same change was not applied to the stores.
However, I'm reluctant to revert a specific change to the assembler,
when the output is obviously correct. With this commit then I simply
bring the expected assembler test results into line with what is
actually produced.

Adaptation of siginfo fixup for the new bnd fields
New bnds fields will be always present for x86 architecture.
Fixup for compatibility layer 32bits has to be fixed.
It was added the nat_siginfo to serving as intermediate step
between kernel provided siginfo and the fix up routine.
When executing compat_siginfo_from_siginfo or
compat_x32_siginfo_from_siginfo first the buffer read from the kernel are
converted into the nat_signfo for homogenization, then the fields of
nat_siginfo are use to set the compat and compat_x32 siginfo fields.
In other to make this conversion independent of the system where gdb
is compiled the most complete version of the siginfo, named as native
siginfo, is used internally as an intermediate step.
Conversion using nat_siginfo is exemplified below:
compat_siginfo_from_siginfo or compat_x32_siginfo_from_siginfo:
buffer (from the kernel) -> nat_siginfo -> 32 / X32 siginfo
(memcpy) (field by field)
siginfo_from_compat_x32_siginfo or siginfo_from_compat_siginfo:
32 / X32 siginfo -> nat_siginfo -> buffer (to the kernel)
(field by field) (memcpy)
Caveat: No support for MPX on x32.

gdb: Guard against undefined behaviour in mi-vla-fortran.exp
The test gdb.mi/mi-vla-fortran.exp reveals an issue with the DWARF
generated by gfortran.
In the test a pointer variable 'pvla2' is created:
real, pointer :: pvla2 (:, :)
Initially this variable will be unassociated, so something like this:
l = associated(pvla2)
should return false.
In the test gdb stops at a point _before_ pvla2 is associated with
anything, and we then try to print pvla2, the expectation is that gdb
should reply <not associated>.
The problem is that the data the DWARF directs gdb to read (to identify
if the variable is associated or not) is not initialised until the first
time pvla2 is accessed.
As a result gdb ends up reading uninitialised memory, sometimes this
uninitialised memory indicates the variable is associated (when it's
not). This first mistake can lead to a cascade of errors, reading
uninitialised memory, with the result that gdb builds an invalid type to
associate with the variable pvla2.
In some cases, this invalid type can be very large, which when we try to
print pvla2 causes gdb to allocate a large amount of memory.
A recent commit added a new gdb variable 'max-value-size', which
prevents gdb from allocating values of extreme size. As a result
directly trying to print pvla2 will now now error rather than allocate a
large amount of memory.
However, some of the later tests create a varobj for pvla2, and then
ask for the children of that varobj to be displayed. In the case where
an invalid type has been computed for pvla2 then the number of children
can be wrong, and very big, in which case trying to display all of these
children can cause gdb to consume an excessive amount of memory.
This commit first detects if printing pvla2 triggers the max-value-size
error, if it does then we avoid all the follow on tests relating to the
unassociated pvla2, which avoids the second error printing the varobj
children.
gdb/testsuite/ChangeLog:
* gdb.mi/mi-vla-fortran.exp: Add XFAIL for accessing unassociated
pointer. Don't perform further tests on the unassociated pointer
if the first test fails.

gdb: New set/show max-value-size command.
For languages with dynamic types, an incorrect program, or uninitialised
variables within a program, could result in an incorrect, overly large
type being associated with a value. Currently, attempting to print such
a variable will result in gdb trying to allocate an overly large buffer.
If this large memory allocation fails then the result can be gdb either
terminating, or (due to memory contention) becoming unresponsive for the
user.
A new user visible variable in gdb helps guard against such problems,
two new commands are available:
set max-value-size
show max-value-size
The 'max-value-size' is the maximum size of memory in bytes that gdb
will allocate for the contents of a value. Any attempt to allocate a
value with a size greater than this will result in an error. The
initial default for this limit is set at 64k, this is based on a similar
limit that exists within the ada specific code.
It is possible for the user to set max-value-size to unlimited, in which
case the old behaviour is restored.

Fix two misleading indentation warnings
Two small changes so everything builds with latest GCC and its
-Wmisleading-indentation.
In the aarch64-tdep.c case, the two misindented lines should actually be
part of the for loop. It looks like the indentation is all done using
spaces in that file though... I fixed it (changed for tabs + spaces) for
the lines I touched.
In the xcoffread.c case, we can simply remove the braces and fix the
indentation.
gdb/ChangeLog:
* aarch64-tdep.c (aarch64_record_asimd_load_store): Add braces
to for include additional lines.
* xcoffread.c (scan_xcoff_symtab): Remove unnecessary braces.

Import strchrnul from gnulib and use it
For a forthcoming patch, I need a "skip_to_colon" function. I noticed
there are two skip_to_semicolon (one in gdb and one in gdbserver). I
thought we could put it in common/, and generalize it for any character.
It turns out that the strchrnul function does exactly that. I imported
the corresponding module from gnulib, for those systems that do not have
it.
There are probably more places where this function can be used instead
of doing the work by hand (I am looking at
remote-utils.c::look_up_one_symbol).
gdb/ChangeLog:
* remote.c (skip_to_semicolon): Remove.

[testsuite] Fix tiemout fail in gdb.fortran/vla-value.exp
In vla.f90, this single line of source is compiled to many instructions,
vla2(:, :, :) = 1311 ! vla2-allocated
it is quite slow (about several minutes in my testing) to step over this
source line without range stepping. This patch is to increase the timeout
value by 15 times, which is a magic number to make sure timeout disappears
in my testing with a slow arm-linux board.

the root cause of this problem in this case is about linespec and
symtab which produces additional incorrect location and a NULL is added to
bp_tgt->tcommands. I posted a patch
https://sourceware.org/ml/gdb-patches/2015-12/msg00321.html to fix it
in linespec (the fix causes regression), but GDB still shouldn't add
NULL into bp_tgt->tcommands. The logic of build_target_command_list
looks odd to me. If we get something wrong in parse_cmd_to_aexpr (it
returns NULL), we shouldn't continue, instead we should set flag
null_command_or_parse_error. This is what this patch does. In the
meantime, we find build_target_condition_list has the same problem, so
fix it too.

The assertion failure which is tripped is:
gdb_assert (arg_size <= 4);
While it may seem that the patch ought to disallow scalars larger than
4, scalars of size 8 are explicitly handled by the code elsewhere.
This came up because gcc has a complex type that is 16 bytes in length
when 64-bit doubles are used.

[GDBserver] Use regcache_read_pc in install_software_single_step_breakpoints
In install_software_single_step_breakpoints, we've got the regcache
of current_thread, so we don't have to bother get_pc to get pc,
instead we can get pc from regcache directly. Note that the callers

[GDBserver] Block and unblock SIGIO
Nowadays, GDBserver disables async io (by ignoring SIGIO) when process
a serial event, and enables async io (by installing signal handler) when
resume the inferior and wait. GDBserver may miss SIGIO (by interrupt)
and doesn't process SIGIO in time, which is shown by
gdb.base/interrupt-noterm.exp. In the test, GDB sends "continue &" and
then "interrupt". if '\003' arrives at a period between GDBserver
receives vCont;c and enables async io, SIGIO is ignored because signal
handler isn't installed. GDBserver waits for the inferior and can not
notice '\003' until it returns from wait.
This patch changes the code to install SIGIO handler early, but block
and unblock SIGIO as needed. In this way, we don't remove SIGIO
handler, so SIGIO can't be ignored. However, GDBserver needs to
remove the signal handler when connection is closed.

[GDBserver] Check input interrupt after reading in a packet
GDBserver may read some packet together with '\003' in one go. We've
already checked '\003' first when reading packet by my patch,
Check input interrupt first when reading packet
https://sourceware.org/ml/gdb-patches/2016-01/msg00057.html
but if we don't check '\003' *after* each packet, the interrupt will
be processed next time GDBserver reads from the buffer, so that the
interrupt isn't processed in time. For example, GDB sends vCont;c and
interrupt (see gdb.base/interrupt-noterm.exp), we'll resume the
inferior and wait once packet vCont;c is seen. If we don't check the
interrupt character after vCont;c packet, interrupt character will stay
in the buffer unattended until GDBserver returns from the wait, which
may take a while. Note that since we've read '\003' from file
descriptor, SIGIO signal handler input_interrupt doesn't help either.
This issue can be exposed by hacking the end of getpkt like
@@ -1041,6 +1050,9 @@ getpkt (char *buf)
}
}
+ if (readchar_bufcnt > 0)
+ gdb_assert (*readchar_bufp != '\003');
+
return bp - buf;
}
and this can trigger internal error,

Fix GCC6 -Wmisleading-indentation issues.
GCC6 will warn about misleading indentation issues like:
gdb/ada-lang.c: In function ‘ada_evaluate_subexp’:
ada-lang.c:11423:9: error: statement is indented as if it were guarded by...
arg1 = unwrap_value (arg1);
^~~~
gdb/ada-lang.c:11421:7: note: ...this ‘else’ clause, but it is not
else
^~~~
In this case it would be a bug except for the fact the if clause already
returned early. So this misindented statement really only got executed
for the else case. But it could easily mislead a reader, so adding a
proper else block is the correct solution.
In case of c-typeprint.c (c_type_print_base) the if statement is indeed
misleadingly indented, but not a bug. Just indent correctly. The inflow.c
(terminal_ours_1) misindented block comes from the removal of an if clause
in commit d9d2d8b which looks correct. Just introduce an else to fixup the
indentation of the block. The linux-record.c misleadingly indented return
statements are just that. Misleading to the reader, but not actual bugs.
Just unindent them so they don't look like they fall under the wrong if
clause.

Fix PR 19461: strange "info thread" behavior in non-stop
If you have "set follow-fork child" set, then if you do "info threads"
right after a fork, and before the child reports any other event to
GDB core, you'll see:
(gdb) info threads
Id Target Id Frame
* 1.1 Thread 0x7ffff7fc1740 (LWP 31875) "fork-plus-threa" (running)
2.1 process 31879 "fork-plus-threa" Selected thread is running.
(gdb)
The "Selected thread is running." bit is a bogus error. That was GDB
trying to fetch the current frame of thread 2.1, because the external
runnning state is "stopped", and then throwing an error because the
thread is actually running.
This actually affects all-stop + schedule-multiple as well.
The problem here is that on a fork event, GDB doesn't update the
external parent/child running states.
New comprehensive test included. The "kill inferior 1" / "kill
inferior 2" bits also trip on PR gdb/19494 (hang killing unfollowed
fork children), which was fixed by the previous patch.

Fix PR 19494: hang when killing unfollowed fork children
linux_nat_kill relies on get_last_target_status to determine whether
the current inferior is stopped at a unfollowed fork/vfork event.
This is bad because many things can happen ever since we caught the
fork/vfork event... This commit rewrites that code to instead walk
the thread list looking for unfollowed fork events, similarly to what
was done for remote.c.
New test included. The main idea of the test is make sure that when
the program stops for a fork catchpoint, and the user kills the
parent, gdb also kills the unfollowed fork child. Since the child
hasn't been added as an inferior at that point, we need some other
portable way to detect that the child is gone. The test uses a pipe
for that. The program forks twice, so you have grandparent, child and
grandchild. The grandchild inherits the write side of the pipe. The
grandparent hangs reading from the pipe, since nothing ever writes to
it. If, when GDB kills the child, it also kills the grandchild, then
the grandparent's pipe read returns 0/EOF and the test passes.
Otherwise, if GDB doesn't kill the grandchild, then the pipe read
never returns and the test times out, like:
FAIL: gdb.base/catch-fork-kill.exp: fork-kind=fork: exit-kind=kill: fork: kill parent (timeout)
FAIL: gdb.base/catch-fork-kill.exp: fork-kind=vfork: exit-kind=kill: vfork: kill parent (timeout)
No regressions on x86_64 Fedora 20. New test passes with gdbserver as
well.

These two tests collect 64 words from $sp onwards, hoping that's enough
to capture a few whole stack frames. Unfortunately, that's not enough
for s390, which tends to have large frame sizes - minimum 24 words on
s390, 20 on s390x (which just barely passes). Bump it to 128 words,
let's hope no machine needs more.

gdb.trace: Fix unavailable-dwarf-piece.exp on big endian targets
The test constructs fake DWARF info for a C structure involving bitfields.
DWARF bitfields are always counted from LSB, while the order in which
bitfields are allocated in a C struct depends on the target endianness -
thus the generated DWARF marks different bitfields as unavailable when
target is big endian. Accordingly, we need different expected outputs.
Tested on s390 and s390x, no regression on x86_64.

gdb.trace: Fix string collection for 64-bit platforms.
String collection always used ref32 to fetch the string pointer. Make it
use gen_fetch instead.
As a side effect, this patch changes dup+const+trace+pop sequence used
for collecting the string's address to a trace_quick opcode. This
results in a shorter agent expression.
This appeared to work on x86_64 since it's a little-endian platform, and
malloc (used in gdb.trace/collection.exp) returns addresses in low 4GB.
Noticed and tested on s390x-ibm-linux-gnu, also tested on
i686-unknown-linux-gnu and x86_64-unknown-linux-gnu.

gdb: Respect CXXFLAGS when building with C++ compiler
Currently, even when built with --enable-build-with-cxx, gdb uses

CXXFLAGS set in the environment when configure was run is now honored
in the generated gdb/Makefile, and you can also override CXXFLAGS in

Fix regression introduced in "break *<EXPR>" by explicit location patches.
A relatively recent patch support for explicit locations, and part
of that patch cleaned up the way we parse breakpoint locations.
Unfortunatly, a small regression crept in for "*<EXPR>" breakpoint
locations. In particular, on PIE programs, one can see the issue by
doing the following, with any program:
(gdb) b *main
Breakpoint 1 at 0x51a: file hello.c, line 3.
(gdb) run
Starting program: /[...]/hello
Error in re-setting breakpoint 1: Warning:
Cannot insert breakpoint 1.
Cannot access memory at address 0x51a
Warning:
Cannot insert breakpoint 1.
Cannot access memory at address 0x51a
Just for the record, this regression was introduced by:
commit a06efdd6effd149a1d392df8d62824e44872003a
Date: Tue Aug 11 17:09:35 2015 -0700
Subject: Explicit locations: introduce address locations
What happens is that the patch makes the implicit assumption that
the address computed the first time is static, as if it was designed
to only support litteral expressions (Eg. "*0x1234"). This allows
the shortcut of not re-computing the breakpoint location's address
when re-setting breakpoints.
However, this does not work in general, as demonstrated in the example
above.
This patch plugs that hole simply by saving the original expression
used to compute the address as part of the address location, so as
to then re-evaluate that expression during breakpoint re-set.

* location.h (new_address_location): Add new parameters
"addr_string" and "addr_string_len".

[AArch64] Relax long branch veneer insertion for non STT_FUNC symbol
As defined at AArch64 ELF Specification (4.6.7 Call and Jump
relocations), symbol with type of non STT_FUNC but in different input
section with relocation place should insert long branch veneer also.
Meanwhile the current long branch veneer infrastructure havn't considered
the situation where the branch destination is "sym_value + rela->addend".
This was OK because we only insert veneer for long call destination is
STT_FUNC symbol for which the addend is always zero. But as we relax the
support to other situations by this patch, we need to handle addend be
non-zero value. For example, for static function, relocation against
"local symbol" are turned into relocation against "section symbol + offset"
where there is a valid addend.

In fact, GDB has taken care of this arm/thumb mode changes already,

Fix sorting of enum values in FlagEnumerationPrinter
The lambda function used to sort the enumerator list does not work
properly. This list consists of tuples, (enum label, enum value). The
key function returns x.enumval. enumval not being defined for a tuple,
we see this exception in the test log:
Python Exception <class 'AttributeError'> 'tuple' object has no attribute 'enumval'
The function should return the second item of the tuple, which is the
enumval.
The pretty-printer still worked mostly correctly, except that the
enumeration values were not sorted. The test still passed because the
enumeration values are already sorted where they are defined. The test
also passed despite the exception being printed, because the right output
was printed after the exception:
print (enum flag_enum) (FLAG_1)
Python Exception <type 'exceptions.AttributeError'> 'tuple' objecthas no attribute 'enumval':M
$7 = 0x1 [FLAG_1]
(gdb) PASS: gdb.python/py-pp-maint.exp: print FLAG_1
New in v2:
- Improved test case, I stole Pedro's example directly. It verifies
that the sorting of enumerators by value works, by checking that
printing FOO_MASK appears as FOO_1 | FOO_2 | FOO_3.
I noticed that I could change the regexps to almost anything and the
tests would still pass. I think it was because of the | in there. I
made them more robust by using string_to_regexp. I used curly braces
{ } instead of quoting marks " " for strings, so that I could use
square brackets [ ] in them without having to escape them all. I also
removed the "message" part of the tests, since they are redundant with
the command, and it's just more maintenance to have to update them.
Tested with Python 2.7 and 3.5.

Fix missing IPA lib in tspeed.exp in some configurations.

Target returns error code '.In-process agent library not loaded in

(gdb) FAIL: gdb.trace/tspeed.exp: start trace experiment
This is because the default is to link with --as-needed and the
gdb_compile for the test is using the libs argument instead of shlib which
corrects this issue since 6ebea266fd0a7a56c90db3ab6237ff9f6c919747 by
adding -Wl,--no-as-needed.

Add support for LWP-based threads on FreeBSD.
Older versions of FreeBSD supported userland threading via a pure
user-space threading library (N threads scheduled on 1 process) and
a N:M model (N threads scheduled on M LWPs). However, modern FreeBSD
versions only support a M:M threading model where each user thread is
backed by a dedicated LWP. This thread target only supports this
threading model. It also uses ptrace to query and alter LWP state
directly rather than using libthread_db to simplify the implementation.
FreeBSD recently gained support for reporting LWP events (birth and death
of LWPs). GDB will use LWP events when present. For older systems it
fetches the list of LWPs in the to_update_thread_list target op to update
the list of threads on each stop.
This target supports scheduler locking by using ptrace to suspend
individual LWPs as necessary before resuming a process.

Fix enum flag with Python 3
Using Python 3.5 (I assume it's the same with 3.4 and lower, but I didn't
test), I see this:
print (enum flag_enum) (FLAG_1)^M
Python Exception <class 'TypeError'> %x format: an integer is required, not gdb.Value: ^M
$7 = ^M
(gdb) FAIL: gdb.python/py-pp-maint.exp: print FLAG_1
Apparently, this idiom, where v is a gdb.Value, was possible with Python 2,
but not with Python 3:
'%x' % v
In Python 2, it would automatically get converted to an integer. To solve
it, I simply added wrapped v in a call to int().
'%x' % int(v)
In Python 2, the int type is implemented with a "long" in C, so on x86-32 it's
32-bits. I was worried that doing int(v) would truncate the value and give
wrong results for enum values > 32-bits. However, the int type != the int
function. The int function does the right thing, selecting the right integer
type for the given value. I tested with large enum values on x86-32 and
Python 2, and everything works as expected.
gdb/ChangeLog:
* python/lib/gdb/printing.py (_EnumInstance.to_string): Explicitly
convert gdb.Value to integer type using int().

testsuite: Add --status to runtest invocation
By default, if a test driver (a test .exp) ends with an uncaught
error/exception, the runtest command will still have a return code of 0
(success). However, if a test (or the environment) is broken and does
not work properly, it should be considered as failed so that we can
notice it and fix it.
Passing the --status flag to runtest will make it return an error if one
of the test it runs ends up with an uncaught error.
gdb/testsuite/ChangeLog:
* Makefile.in (check-single): Pass --status to runtest.
(check/%.exp): Likewise.

testsuite: Make check-parallel return non-zero if a test failed
When using the check-parallel target, the return code of make is always 0,
regardless of test results. This patch makes it return the same code as
the "make do-check-parallel" sub-command. So if there is a FAIL somewhere,
non-zero will be returned by make.
For the sake of example, I introduced a failure in gdb.base/break.exp.
$ make check-single TESTS="gdb.base/break.exp gdb.python/py-value.exp" && echo 'Success :D' || echo 'Fail :('
...
FAIL: gdb.base/break.exp: allo
...
Fail :(
I think the parallel run should do the same. Currently:
$ make check-parallel TESTS="gdb.base/break.exp gdb.python/py-value.exp" && echo 'Success :D' || echo 'Fail :('
...
FAIL: gdb.base/break.exp: allo
...
Success :D
And with the patch (no big surprises there):
$ make check-parallel TESTS="gdb.base/break.exp gdb.python/py-value.exp" && echo 'Success :D' || echo 'Fail :('
...
FAIL: gdb.base/break.exp: allo
...
Fail :(
What do you think?
gdb/testsuite/ChangeLog:
* Makefile.in (check-parallel): Propagate return code from make
do-check-parallel.

Limit breakpoint re-set to the current program space
Currently, we always re-set all locations of all breakpoints. This
commit makes us re-set only locations of the current program space.
If we loaded symbols to a program space (e.g., "file" command or some
shared library was loaded), GDB must run through all breakpoints and
determine if any new locations need to be added to the breakpoint.
However, there's no reason to recreate locations for _other_ program
spaces, as those haven't changed.
Similarly, when we create a new inferior, through e.g., a fork, GDB
must run through all breakpoints and determine if any new locations
need to be added to the breakpoint. There's no reason to destroy the
locations of the parent inferior and other inferiors. We know those
won't change.
In addition to being inneficient, resetting breakpoints of inferiors
that are currently running is problematic, because:
- some targets can't read memory while the inferior is running.
- the inferior might exit while we're re-setting its breakpoints,
which may confuse prologue skipping.
I went through all the places where we call breakpoint_re_set, and it
seems to me that all can be changed to only re-set locations of the
current program space.
The patch that reversed threads order in "info threads" etc. happened
to make gdb.threads/fork-plus-thread.exp expose this problem when
testing on x86/-m32. The problem was latent and masked out by chance
by the code-cache:
https://sourceware.org/ml/gdb-patches/2016-01/msg00213.html
Tested on x86-64 F20, native (-m64/-m32) and extended-remote
gdbserver.
Fixes the regression discussed in the url above with --target_board=unix/-m32:
-FAIL: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: inferior 1 exited
+PASS: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: inferior 1 exited
-FAIL: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: no threads left (timeout)
-FAIL: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: only inferior 1 left (the program exited)
+PASS: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: no threads left
+PASS: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: only inferior 1 left

This is fallout from f303dbd60d9c7984832446eeb9d4e4d89703c615.
The testcases themselves are single-threaded, but they load the IPA library,
which injects a thread in the inferior - making them multithreaded.
This results in printing the thread numbers in breakpoint messages.

MIPS: Remove remnants of 48-bit microMIPS instruction support
The POOL48A major opcode was defined in early revisions of the 64-bit
microMIPS ISA, has never been implemented, and was removed before the
64-bit microMIPS ISA specification[1] has been finalized.
This complements commit a6c7053929dd ("MIPS/opcodes: Remove microMIPS
48-bit LI instruction").

MIPS: Only build microMIPS specific simulator functions if microMIPS support is required.
This fixes PR sim/19441. In the MIPS simulator the microMIPS
functions in micromips.igen were not predicated on the microMIPS
models. This was causing build issues for some target triples.
This patch sets all the microMIPS specific functions to only be built if
the micromips32, micromips64 or micromipsdsp models are used.

MIPS: Fix microMIPS instruction size determination
Fix a bug in `micromips_insn_at_pc_has_delay_slot' in instruction size
determination via `mips_insn_size'. In the microMIPS case the latter
function expects a lone 16-bit instruction word containing the major
opcode regardless of whether the opcode requires another 16-bit word to
follow, to form a complete 32-bit instruction. Code however passes the
16-bit word previously retrieved shifted left by 16 bits. Consequently
`mips_insn_size', which examines the low 16-bit only, always sees 0.
By pure coincidence a major opcode of 0 denotes a 32-bit instruction in
the microMIPS instruction set, so the size of 4 is always returned here,
and the following 16-bit word is then merged in the low 16 bits of the
instruction previously shifted by 16 bits. The resulting 32-bit value
is then passed to `micromips_instruction_has_delay_slot' for delay slot
presence determination. This function in turn first examines the high
16 bits of the instruction word received and ignores the low 16 bits for
16-bit instructions.
Consequently the only effect of this bug is an extraneous memory read
issued to retrieve a subsequent 16-bit word where a 16-bit instruction
is being examined. Which in turn may fail if the instruction is located
right at the end of a readable memory area, in which case the lack of a
delay slot will be reported to the caller, which may be incorrect.
This code is used in breakpoint maintenance, for delay slot avoidance,
so the bug would only trigger for the unlikely case of someone placing
a breakpoint in a delay slot of an instruction which is at the end of
readable memory. Which explains why the bug remained unnoticed so long.

Fix PR threads/19422 - show which thread caused stop
This commit changes GDB like this:
- Program received signal SIGINT, Interrupt.
+ Thread 1 "main" received signal SIGINT, Interrupt.
- Breakpoint 1 at 0x40087a: file threads.c, line 87.
+ Thread 3 "bar" hit Breakpoint 1 at 0x40087a: file threads.c, line 87.
... once the program goes multi-threaded. Until GDB sees a second
thread spawn, the output is still the same as before, per the
discussion back in 2012:
https://www.sourceware.org/ml/gdb/2012-11/msg00010.html
This helps non-stop mode, where you can't easily tell which thread hit
a breakpoint or received a signal:
(gdb) info threads

(gdb)
Breakpoint 1, thread_function1 (arg=0x1) at threads.c:87
87 usleep (1); /* Loop increment. */
The best the user can do is run "info threads" and try to figure
things out.
It actually also affects all-stop mode, in case of "handle SIG print
nostop":
...
Program received signal SIGUSR1, User defined signal 1.
Program received signal SIGUSR1, User defined signal 1.
Program received signal SIGUSR1, User defined signal 1.
Program received signal SIGUSR1, User defined signal 1.
...
The above doesn't give any clue that these were different threads
getting the SIGUSR1 signal.
I initially thought of lowercasing "breakpoint" in
"Thread 3 hit Breakpoint 1"
but then after trying it I realized that leaving "Breakpoint"
uppercase helps the eye quickly find the relevant information. It's
also easier to implement not showing anything about threads until the
program goes multi-threaded this way.
Here's a larger example session in non-stop mode:

Replace some $ARCH_{get,set}_pc with linux_{get,set}_pc_64bit
This patch is the follow-up of
https://sourceware.org/ml/gdb-patches/2016-01/msg00164.html to provide
linux_{get,set}_pc_64bit functions.
Rebuild GDBserver with tilegx-linux-gcc. Not tested.
I think about pc in Tile-GX a little bit. Looks current Tile-GX
supports debugging 32-bit program (multi-arch), but PC is always
64-bit. See this thread
https://sourceware.org/ml/gdb-patches/2013-02/msg00113.html
and GDBserver reads PC as 64-bit through ptrace. However, if
the inferior is 32-bit, the PC in the target description and
regcache is 32-bit, so only 32-bit contents are sent back GDB.
Anyway, Tile-GX GDBserver may have some problems here, but this
patch doesn't change anything.

m68hc11/12 and xgate config.sub weirdness
Oddly, config.sub converts a duple ending in -elf for these target to
-unknown-none, which means they aren't seen as elf targets by
binutils. So, counter that. This exposes a number of testsuite
issues (ones you would have seen if configuring with a full triple,
say m68hc11-unknown-elf).
binutils/
* testsuite/lib/binutils-common.exp (is_elf_format): Return true
for m68hc11/12 and xgate triples.

Fix "thread apply $conv_var" and misc other related problems
This fixes a few bugs in "thread apply".
While this works:
(gdb) thread apply 1 p 1234
Thread 1 (Thread 0x7ffff7fc1740 (LWP 14048)):
$1 = 1234
This doesn't:
(gdb) thread apply $thr p 1234
Thread 1 (Thread 0x7ffff7fc1740 (LWP 12039)):
Invalid thread ID: p 1234
(gdb)
~~~~
Also, while this works:
(gdb) thread apply 1
Please specify a command following the thread ID list
This doesn't:
(gdb) thread apply $thr
Thread 1 (Thread 0x7ffff7fc1740 (LWP 12039)):
[Current thread is 1 (Thread 0x7ffff7fc1740 (LWP 12039))]
(gdb)
~~~~
And, while this works:
(gdb) thread apply
Please specify a thread ID list
This obviously bogus invocation is just silent:
(gdb) thread apply bt
(gdb)
gdb/ChangeLog:
2016-01-15 Pedro Alves <palves@redhat.com>
* thread.c (thread_apply_command): Use the tid range parser to
advance past the thread ID list.
* tid-parse.c (get_positive_number_trailer): New function.
(parse_thread_id): Use it.
(get_tid_or_range): Use it. Return 0 instead of throwing invalid
thread ID error.
(get_tid_or_range): Detect negative values. Return 0 instead of
throwing invalid thread ID error.
gdb/testsuite/ChangeLog:
2016-01-15 Pedro Alves <palves@redhat.com>
* gdb.multi/tids.exp (thr_apply_info_thr_error): Remove "p 1234"
command from "thread apply" invocation.
(thr_apply_info_thr_invalid): Default the expected output to the
input tid list.
(top level): Add tests that use convenience variables. Add tests
for "thread apply" with a valid TID list, but missing the command.
