ARC naughtiness causing assertion fail at elf-strtab.c:302
This patch fixes a number of issues in the ARC backend.
- The ARC size_dynamic_sections was trashing dynamic section contents,
in particular the .gnu.version_d contents. Those versions
definitions are therefore lost so they do not drain from the strtab,
resulting in assertion failures.
- The code attempting to set DT_TEXTREL was completely bogus.
- The ARC finish_dynamic_sections would segfault on trying to set
sh_entsize for .rela.plt if that section had been discarded.
- arc_create_dynamic_sections wouldn't have ever created dynamics
sections, which was just as well since the places it was called were
way too late to create dynamic sections. Its usefulness then
devolved down to finding just one dynamic section. All the others
packaged into a struct were unused.
- .interp wasn't set for PIEs.
* elf32-arc.c (struct dynamic_sections): Delete.
(enum dyn_section_types): Delete.
(dyn_section_names): Delete.
(arc_create_dynamic_sections): Delete.
(elf_arc_finish_dynamic_sections): Don't call the above. Don't
segfault on discarded .rela.plt section.
(elf_arc_size_dynamic_sections): Formatting. Don't call
arc_create_dynamic_sections. Don't allocate memory for sections
handled by the generic linker. Correct code finding relocs in
read-only sections. Set SEC_EXCLUDE on zero size .got,
.got.plt, and .dynbss sections. Do set .interp for pies.

readelf: Correct version flag formatting
Remove a trailing space or a leading pipe character from version flags
printed with `readelf --version-info'.
For example with the `mips-linux' target we get:
$ cat ver_def.s
.data
.globl new_foo
.type new_foo, %object
new_foo:
.symver new_foo, foo@@ver_foo
$ cat ver_def.ver
{ global: *foo*; local: *; };
$ as -o ver_def.o ver_def.s
$ ld -e 0 --export-dynamic --version-script=ver_def.ver -o ver_def ver_def.o
$ readelf -V ver_def
Version symbols section '.gnu.version' contains 4 entries:
Addr: 000000000000007e Offset: 0x01007e Link: 2 (.dynsym)
000: 0 (*local*) 2 (ver_foo) 1 (*global*) 2 (ver_foo)
Version definition section '.gnu.version_d' contains 2 entries:
Addr: 0x0000000000000088 Offset: 0x010088 Link: 3 (.dynstr)
000000: Rev: 1 Flags: BASE Index: 1 Cnt: 1 Name: ver_def
0x001c: Rev: 1 Flags: none Index: 2 Cnt: 1 Name: ver_foo
$
which includes an unnecessary space after `BASE'; both call sites
already provide suitable separation from output that follows. Also if
only unknown flags were present, then lone `| <unknown>' would be
printed.

readelf: Fix incorrect "Version definition past end of section" message
Fix a commit 74e1a04b9787 ("More fixes for reading corrupt ELF files.")
`readelf --version-info' regression that caused "Version definition past
end of section" to be always printed at the end, even with good section
data.
For example with the `mips-linux' target we get:
$ cat ver_def.s
.data
.globl new_foo
.type new_foo, %object
new_foo:
.symver new_foo, foo@@ver_foo
$ cat ver_def.ver
{ global: *foo*; local: *; };
$ as -o ver_def.o ver_def.s
$ ld -e 0 --export-dynamic --version-script=ver_def.ver -o ver_def ver_def.o
$ readelf -V ver_def
Version symbols section '.gnu.version' contains 4 entries:
Addr: 000000000000007e Offset: 0x01007e Link: 2 (.dynsym)
000: 0 (*local*) 2 (ver_foo) 1 (*global*) 2 (ver_foo)
Version definition section '.gnu.version_d' contains 2 entries:
Addr: 0x0000000000000088 Offset: 0x010088 Link: 3 (.dynstr)
000000: Rev: 1 Flags: BASE Index: 1 Cnt: 1 Name: ver_def
0x001c: Rev: 1 Flags: none Index: 2 Cnt: 1 Name: ver_foo
Version definition past end of section
$
The cause is the `if (idx + ent.vd_next <= idx)' condition introduced to
ensure forward progress, which however always triggers for good version
definition section data as the last entry will have its `vd_next' value
set to 0.
Adjust the condition then, to say `if (idx + ent.vd_next < idx)' instead
and to ensure forward progress limit the number of entries processed to
the size of the version definition section, removing the problematic
message from output quoted above, while ensuring the original PR 17531
test case is still handled gracefully.
Add a suitable test case so that we have `readelf --version-info'
coverage; due to the lack of infrastructure needed to run the linker in
the `binutils' test suite and limited justification to implement it add
a new `readelf.exp' script to the `ld' test suite instead, intended to
gather any `readelf' test cases that require the linker to be run. If
ever we decide to have linker infrastructure added to the `binutils'
test suite, then the script can be moved between the test suites.
binutils/
* readelf.c (process_version_sections) <SHT_GNU_verdef>: Limit
the number of entries processed by the section size. Don't
break out of the loop if `ent.vd_next' is 0.

MIPS/BFD: Remove duplicate NewABI JALR relocation handling
Remove separate original NewABI JALR relocation handling, introduced
with commit d06471104a83 ("relax jalr $t9 [R_MIPS_JALR symbol] to bal
symbol"), <https://sourceware.org/ml/binutils/2003-03/msg00394.html>,
and only used by LD with the `--relax' option specified, and rely solely
on `mips_elf_perform_relocation' code, which has been introduced with
commit 1367d393bb74 ("On the RM9000 convert jal to bal if in range"),
<https://www.sourceware.org/ml/binutils/2004-12/msg00088.html> and since
made more complete, across all the three ABIs.
Also remove the `--relax' option, now irrelevant, from the tests added
with the former commit.

MIPS/BFD: Discard ineligible JALR relocations right away
Discard R_MIPS_JALR and R_MICROMIPS_JALR relocations associated with
jumps that cannot be converted to an equivalent branch right away in
`mips_elf_calculate_relocation' rather than letting them through to
`mips_elf_perform_relocation'. This includes cross-mode jumps which
need to flip the ISA bit or jumps to a misaligned location that cannot
be encoded with a branch, in addition to preemptible symbol references
already handled.
Cross-mode jumps are actually already rejected as the conversion is made
in `mips_elf_perform_relocation', so in this case this change only saves
some processing. Jumps to a misaligned location are however converted,
with bits causing misalignment lost, making resulting code functionally
different even if the lone effect is avoiding an address error exception
with an instruction fetch at the jump destination requested.
Add test cases suitable, also including GAS verification to confirm that
the JALR relocations explicitly requested have indeed been output in the
intermediate objects used.

S/390: Add support for new cpu architecture - arch12.
This adds support of new instructions to the S/390 specific parts.
The important feature of the new instruction set is the support of
single and extended precision floating point vector operations.
Note: arch12 is NOT the official name of the new CPU. It just
continues the series of archXX options supported as alternate names.
The archXX terminology refers to the edition number of the Principle
of Operations manual. The official CPU name will be added later while
keeping support of the arch12 for backwards compatibility.
No testsuite regressions.
Committed to mainline.

Use gdb::function_view in iterate_over_symtabs & co
I wanted to pass a lambda to iterate_over_symtabs (see following
patch), so I converted it to function_view, and then the rest is
cascaded from that.
This gets rid of a bunch of single-use callback functions and
corresponding manually managed callback capture types
(add_partial_datum, search_symbols_data, etc.) in favor of letting the
compiler generate them for us by using lambdas with a capture. In a
couple cases, it was more natural to convert the existing function
callbacks to function objects (i.e., operator(), e.g.,
decode_compound_collector).

Introduce gdb::function_view
This commit adds a new function_view type. This type holds a
non-owning reference to a callable. It is meant to be used as
callback type of functions, instead of using the C-style pair of
function pointer and 'void *data' arguments. function_view allows
passing references to stateful function objects / lambdas with
captures as callbacks efficiently, while function pointer + 'void *'
does not.
See the intro in the new function-view.h header for more.
Unit tests included, put into a new gdb/unittests/ subdir.

While inspecting some target code, I noticed that in these two
implementations of thread_alive, inferior_ptid is referenced directly
instead of using the ptid passed as parameters. I guess that it is
wrong, although I can't really test it in both cases.
gdb/ChangeLog:
* bsd-uthread.c (bsd_uthread_thread_alive): Use ptid instead of
inferior_ptid.
* go32-nat.c (go32_thread_alive): Likewise.

readelf: Restore a lost new line in version information
Fix a commit 74e1a04b9787 ("More fixes for reading corrupt ELF files.")
`readelf --version-info' output formatting regression where a dropped
new line caused section header information from the `.gnu.version_d'
version definition section to be printed on the same line as this
section's first entry.
For example with the `mips-linux' target we get:
$ cat ver_def.s
.data
.globl new_foo
.type new_foo, %object
new_foo:
.symver new_foo, foo@@ver_foo
$ cat ver_def.ver
{ global: *foo*; local: *; };
$ as -o ver_def.o ver_def.s
$ ld -e 0 --export-dynamic --version-script=ver_def.ver -o ver_def ver_def.o
$ readelf -V ver_def
Version symbols section '.gnu.version' contains 4 entries:
Addr: 000000000000007e Offset: 0x01007e Link: 2 (.dynsym)
000: 0 (*local*) 2 (ver_foo) 1 (*global*) 2 (ver_foo)
Version definition section '.gnu.version_d' contains 2 entries:
Addr: 0x0000000000000088 Offset: 0x010088 Link: 3 (.dynstr) 000000: Rev: 1 Flags: BASE Index: 1 Cnt: 1 Name: ver_def
0x001c: Rev: 1 Flags: none Index: 2 Cnt: 1 Name: ver_foo
Version definition past end of section
$
Add the new line then, to get:
$ readelf -V ver_def
Version symbols section '.gnu.version' contains 4 entries:
Addr: 000000000000007e Offset: 0x01007e Link: 2 (.dynsym)
000: 0 (*local*) 2 (ver_foo) 1 (*global*) 2 (ver_foo)
Version definition section '.gnu.version_d' contains 2 entries:
Addr: 0x0000000000000088 Offset: 0x010088 Link: 3 (.dynstr)
000000: Rev: 1 Flags: BASE Index: 1 Cnt: 1 Name: ver_def
0x001c: Rev: 1 Flags: none Index: 2 Cnt: 1 Name: ver_foo

$
instead.

PR ld/20828: Move symbol version processing ahead of GC symbol sweep
Complement commit b531344c34b0 ("PR ld/20828: Reorder the symbol sweep
stage of section GC") and commit 81ff47b3a546 ("PR ld/20828: Fix linker
script symbols wrongly forced local with section GC") and move symbol
version processing ahead of the symbol sweep stage of section GC, all in
`bfd_elf_size_dynamic_sections', so that version symbols created stay in
the global scope and are not output as local symbols to the dynamic
symbol table in the presence of corresponding symbol definitions pulled
from a DSO involved in a link.
Consolidate the whole of symbol version processing into a single block
from all parts scattered across the function and rearranging the local
variables used as necessary, however leaving the setting of dynamic
entries associated with the DT_VERDEF, DT_VERDEFNUM, DT_VERNEED and
DT_VERNEEDNUM tags and the SEC_EXCLUDE flag for unused `.gnu.version'
section in the original places.
With the rearrangement of code blocks `Elf_Internal_Verneed *t' would
shadow the previous definition of `struct bfd_elf_version_tree *t', so
rename the former variable to `vn'.

GAS: Consistently fix labels at the `.end' pseudo-op
Fix a functional regression with the `.end' pseudo-op, introduced with
commit ecb4347adecd ("Last take: approval for MIPS_STABS_ELF killing"),
<https://sourceware.org/ml/binutils/2002-06/msg00443.html>, and commit
dcd410fe1544 ("GNU as 2.14 on IRIX 6: crashes with shared libs"),
<https://sourceware.org/ml/binutils/2003-07/msg00415.html>, which caused
symbol values for labels placed between the end of a function's contents
and its terminating `.end' followed by one of the alignment pseudo-ops
to be different depending on whether either `-mdebug', or `-mno-pdr', or
neither of the command-line options is in effect, be it implied or
specified.
Given debug-label-end.s as follows and the `mips-linux' target we have:
$ cat debug-label-end.s
.text
.globl foo
.globl bar
.align 4, 0
.ent foo
foo:
nop
.aent bar
bar:
.insn
.end foo
.align 4, 0
.space 16
.globl baz
.ent baz
baz:
nop
.end baz
.align 4, 0
.space 16
$ as -o debug-label-end.o debug-label-end.s
$ readelf -s debug-label-end.o | grep bar
9: 00000004 0 FUNC GLOBAL DEFAULT 1 bar
$ as -mdebug -o debug-label-end.o debug-label-end.s
$ readelf -s debug-label-end.o | grep bar
9: 00000010 0 FUNC GLOBAL DEFAULT 1 bar
$ as -mno-pdr -o debug-label-end.o debug-label-end.s
$ readelf -s debug-label-end.o | grep bar
8: 00000010 0 FUNC GLOBAL DEFAULT 1 bar
$
The reason is the call to `md_flush_pending_output', which in the case
of `mips*-*-*' targets expands to `mips_emit_delays', which in turn
calls `mips_no_prev_insn', which calls `mips_clear_insn_labels', which
clears the list of outstanding labels. That list is in turn consulted
in `mips_align', called in the interpretation of alignment directives,
and the labels adjusted to the current location.
A call to `md_flush_pending_output' is only made from `s_mips_end' and
then only if `-mpdr' is in effect, which is the default for `*-*-linux*'
and some other `mips*-*-*' targets. A call to `md_flush_pending_output'
is never made from `ecoff_directive_end', which is used in place of
`s_mips_end' when `-mdebug' is in effect. Consequently if `-mno-pdr' or
`-mdebug' is in effect the list of outstanding labels makes it through
to any alignment directive that follows and the labels are differently
interpreted depending on the command-lines options used. And we want
code produced to be always the same.
Call `md_flush_pending_output' unconditionally then in `s_mips_end' and
add such a call from `ecoff_directive_end' as well, as long as the macro
is defined. While `ecoff_directive_end' is shared among targets, the
only one other than `mips*-*-*' actually using it is `alpha*-*-*' and it
does not define `md_flush_pending_output'. So the semantics isn't going
to change for it and neither it has to have its `s_alpha_end' updated
or have code in `ecoff_directive_end' conditionalized.

DWARF-5: DW_FORM_data16
DWARF-5 has new form DW_FORM_data16. The problem is that GDB cannot pass
16-byte constant as a constant value as that would require GDB to use GCC
extension __int128.
Formerly such data was coded as DW_FORM_block* so GDB still decodes
DW_FORM_data16 like DW_FORM_block*.

Code cleanup: Split dwarf2_ranges_read to a callback
DWARF-5 has .debug_rnglists which is somehow similar to .debug_ranges.
This patch converts dwarf2_ranges_read to dwarf2_ranges_process which can work
with both DWARF kinds of range lists through a callback.
It also simplifies dwarf2_record_block_ranges which can benefit from it.

PR gdb/16188: Verify PTRACE_TRACEME succeeded
This patch fixes PR gdb/16188, which is about the fact that
fork_inferior doesn't verify the return value of the "traceme_fun"
callback. On most targets, this callback is actually a wrapper to a
ptrace call that does a PTRACE_TRACEME on the forked GDB process that
will eventually become the inferior.
Thanks to Pedro, this second version of the patch is simpler and more
more logical. Basically, two helper functions are added:
trace_start_error and trace_start_error_with_name. The former can be
used when there is a customized error message to be printed to the
user. The latter works like perror_with_name, so you just need to
pass the function that error'd.
Both helper functions mentioned above do basically the same thing:
print the error message to stderr and call _exit, properly terminating
the forked inferior.
Most of the patch takes care of guarding the necessary system calls
against errors on the "traceme_fun" callbacks. It is not right to
call error on these situations, so I've replaced these calls with the
proper helper function call.
Regression-tested on BuildBot.

GAS: Add ECOFF `.aent' pseudo-op support
Implement the ECOFF `.aent' pseudo-op for ECOFF-style `.mdebug' section
support with ELF objects and, for consistency, also with ECOFF objects.
This is so that the same MIPS source can be assembled without and with
`.mdebug' section generation enabled.
Taking the `gas/testsuite/gas/mips/aent.s' test case source as an
example and the `mips-linux' target we have:
$ as -o aent.o aent.s
$ as -mdebug -o aent.o aent.s
aent.s: Assembler messages:
aent.s:10: Error: unknown pseudo-op: `.aent'
$
because for the !ECOFF_DEBUGGING case (which is the default) the
pseudo-op is already handled by the MIPS backend with `s_mips_ent',
however no handler is present for the opposite case.
For the MIPS target this is a functional regression introduced with
commit ecb4347adecd ("Last take: approval for MIPS_STABS_ELF killing"),
<https://sourceware.org/ml/binutils/2002-06/msg00443.html>, where
support for the `.mdebug' section was added along with its associated
`-mdebug'/`-no-mdebug' command-line options, bringing an inconsistency
between the assembly syntax supported for each of these options as far
as the `.aent' pseudo-op is concerned.
Assembly language documentation available describes the pseudo-op
respectively as follows[1]:
"
.aent name, symno Sets an alternate entry point for the current
procedure. Use this information when you want
to generate information for the debugger. It must
appear inside an .ent/.end pair."
and[2]:
"
.aent name [,symno]
Sets an alternate entry point for the current procedure. Use this
information when you want to generate information for the debugger.
This directive must appear between a pair of .ent and .end directives.
(The optional symno is for compiler use only. It refers to a dense
number in a .T file (symbol table).)"
Copy the approach from `s_mips_ent' then and add `.aent' support to the
`.ent' pseudo-op handler shared between the ELF and ECOFF object file
format backends, by setting BSF_FUNCTION for the symbol requested.

Add support for Intel PKRU register to GDB and GDBserver.
This patch adds support for the registers added by the
Memory Protection Keys for Userspace (PKU aka PKEYs) feature.
Native and remote debugging are covered by this patch.
The XSAVE area is extended with a new state containing
the 32-bit wide PKRU register. The new register is added to
amd64-avx-mpx_avx512-* tdesc, thus it is renamed accordingly. Also,
respective xstate mask X86_XSTATE_AVX_MPX_AVX512_MASK is renamed to
X86_XSTATE_AVX_MPX_AVX512_PKU_MASK to reflect the new feature set
it supports.

commit a1fa17ee1556b0175afb081a7b8a13710246307a
Author: Michael Sturm <michael.sturm@intel.com>
Date: Tue Mar 22 16:26:09 2016 +0100
Add target description for avx-avx512.
Add a dedicated target description for the feature combination
avx-avx512 as implemented by certain IA CPU models.
The corresponding X86_XSTATE_AVX_AVX512_MASK already exists, but shared
the tdesc with X86_XSTATE_AVX_MPX_AVX512_MASK. This caused MPX registers
displayed as undefined on CPUs that only implemented
X86_XSTATE_AVX_AVX512_MASK, which is undesired. This patch solves this issue.
This patch also corrects the wrong usage of x32-avx-mpx-avx512, which is
replaced by x32-avx-avx512. The MPX feature is not implemented in x32 mode.

Rename target descriptions to reflect actual content of description.
To better reflect the actual feature set covered by the IA target
descriptions, the existing descriptions are renamed. Each feature of
the extended state is added to the name of a description or xstate mask
starting from AVX.
For example, amd64-mpx-avx512-linux becomes amd64-avx-mpx-avx512-linux,
while amd64-avx-linux remains unchanged.
Likewise, the corresponding xstate masks are changed, e.g. from
X86_XSTATE_MPX_AVX512_MASK to X86_XSTATE_AVX_MPX_AVX512_MASK.

Change xstate_bv handling to use 8 bytes of data.
The size of the state-component bitmap as specified in
Intel(R) 64 and IA-32 Architectures Software Developer's Manual,
Chapter 13.4.2 is 8 bytes.
So far, the data types used for xstate_bv_p (gdb_byte*),
clear_bv (unsigned int) and tdep->xcr0 (uint64_t) were
inconsistent. But, since the xstate components were still
fitting into a single byte, the code still worked
as expected.
However, with the addition of the PKU feature (bit 9),
using one byte for the bitmap will no longer be sufficient.
This patch changes related code to use 64 bit data types
consistently and changes read/write acces of the XSAVE
header in the xsave buffer to use the endianess-aware
functions extract_unsigned_integer and store_unsigned_integer.
This is required to make sure that eventual differences
in endianess between host and target are taken care off.
gdb/Changelog:
2016-04-18 Michael Sturm <michael.sturm@intel.com>
* i387-tdep.c (i387_supply_xsave): Change type
of clear_bv to ULONGEST. Replace gdb_byte *xstate_bv_p
with ULONGEST xstate_bv and use extract_unsigned_integer
and store_unsigned_integer to read/write its value from
the xsave buffer.
(i387_collect_xsave): Replace gdb_byte *xstate_bv_p
with ULONGEST initial_xstate_bv and use
extract_unsigned_integer/store_unsigned_integer to
read/write its value from the xsave buffer.
Change type of clear_bv to ULONGEST.

bfd: Rename Chunk and S3Forced
The direct references in objcopy kind of look like a hack to me, so
I'm calling these symbols internal too. Certainly they aren't named
and documented as a public BFD symbol today anyway.
So ... give these bfd-internal symbols with external linkage a _bfd_
prefix to avoid collisions in the global symbol namespace.
While at it, give them names that more closely match the corresponding
option name that toggles them.
Also while at it, fix a few related comment typos.

bfd: Improve lookup of file / line information for errors
When looking up file and line information (used from the linker to
report error messages) if no symbol is passed in, then use the symbol
list to look for a matching symbol.
If a matching symbol is found then use this to look up the file / line
information.
This should improve errors when looking up file / line information for
data sections. Hopefully we should find a matching data symbol, which
should, in turn (we hope) match a DW_TAG_variable in the DWARF, this
should allow us to give accurate file / line errors for data symbols.
As the hope is to find a matching DW_TAG_variable in the DWARF then we
ignore section symbols, and prefer global symbols to locals.

* dwarf2.c (_bfd_dwarf2_find_nearest_line): Perform symbol lookup

bfd/dwarf: Improve use of previously loaded dwarf information
When parsing DWARF data in order to report file/line type error messages
we perform section placement to make section addresses unique within
relocatable object files.
Currently, if we reuse previously loaded (and cached) dwarf data then we
neglect to perform section placement, the result is that the section
addresses will not be unique, and we might, incorrectly associate an
address with the wrong debug information, and so report an incorrect
file and line number.
Further we neglect to check that that bfd for which we are looking up
debug information is actually the bfd for which the previous debug
information was loaded, it is possible that we will reuse previously
loaded debug information for a different bfd.
And finally, due to following of gnu_debuglink links in one bfd to
another, the process of checking that the cached debug information is
valid requires us to track the original bfd in the cached debug
information. The original debug information here is either the bfd that
we're interested in, not the bfd we finally load the debug information
from.
bfd/ChangeLog:
* dwarf2.c (struct dwarf2_debug): Add orig_bfd member.
(_bfd_dwarf2_slurp_debug_info): If stashed debug information does
not match current bfd, then reload debug information. Record bfd
we're loading debug info for in the stash. If we have debug
informatin in the cache then perform section placement before
returning.

ld: Add additional checking for warnings/errors in testsuite
This commit adds new actions to the run_cc_link_tests mechanism in the
linker testsuite.
Previously this procedure could take a parameter containing a regular
expression that would be matched against warnings from the linker.
After this commit the warnings parameter is removed, instead, the
actions list can contain the actions 'warning', 'error',
'warning_output', or 'error_output'. The action names are chosen to
match the actions already present in the run_dump_test procedure.
These new actions allow for the current warning checking, but also allow
for checking of errors using a regular expression. More interestingly,
the *_output actions allow for the warning/error patterns to be placed
in a separate file.
The small number of tests that make use of the warning parameter have
been updated to the new mechanism. Later commits will make use of the
new features added in this commit.
ld/ChangeLog:
* testsuite/lib/ld-lib.exp (run_cc_link_tests): Add warning,
error, warning_output, and error_output actions. Remove separate
warnings parameter.
* testsuite/ld-elf/shared.exp (build_tests): Updated to use
'warning' action.

LD: vfinfo: Make clever formatters consistent WRT function name reporting
Remove an inconsistency in linker error message processing causing that
it depends on the ability to infer the name of the originating source
file whether or not the name of the offending function is repeated by
clever formatters for each issue reported within the function.
Taking the `ld/testsuite/ld-powerpc/tocopt7.s' test case source as an
example and the `powerpc-linux' target we have:
$ as -gdwarf2 -o tocopt.o -a64 tocopt.s
$ ld -o tocopt -melf64ppc tocopt.o
tocopt.o: In function `_start':
tocopt.s:35:(.text+0x14): toc optimization is not supported for 0x3fa00000 instruction.
tocopt.s:49:(.text+0x34): toc optimization is not supported for 0x3fa00000 instruction.
$
vs:
$ as -o tocopt.o -a64 tocopt.s
$ ld -o tocopt -melf64ppc tocopt.o
tocopt.o: In function `_start':
(.text+0x14): toc optimization is not supported for 0x3fa00000 instruction.
tocopt.o: In function `_start':
(.text+0x34): toc optimization is not supported for 0x3fa00000 instruction.
$
Similarly with the `mips-linux' target and this source:
$ cat jal-global-multi-overflow.s
.text
.set noreorder
.space 0x2000
.align 4
.globl foo
.ent foo
foo:
jal bar
nor $0, $0
jal bar
nor $0, $0
.end foo
.space 0x1ff0
.align 4
.globl bar
.ent bar
bar:
jal foo
nor $0, $0
jal foo
nor $0, $0
.end bar
$ as -o jal-global-multi-overflow.o jal-global-multi-overflow.s
$ ld -Ttext 0x1fffd000 -e foo -o jal-global-multi-overflow jal-global-multi-overflow.o
jal-global-multi-overflow.o: In function `foo':
(.text+0x2000): relocation truncated to fit: R_MIPS_26 against `bar'
jal-global-multi-overflow.o: In function `foo':
(.text+0x2008): relocation truncated to fit: R_MIPS_26 against `bar'
jal-global-multi-overflow.o: In function `bar':
(.text+0x4000): relocation truncated to fit: R_MIPS_26 against `foo'
jal-global-multi-overflow.o: In function `bar':
(.text+0x4008): relocation truncated to fit: R_MIPS_26 against `foo'
$
Not only this is inconsistent, but it causes output clutter as well with
redundant information.
The cause for this is a check in `vfinfo' the intent of which is to
print the function heading whenever (among others) the name of the
source file has changed, which however does not take into account a
situation where the name couldn't have been established both now and
previously.
Adjust the check then for this situation, yielding:
$ as -o tocopt.o -a64 tocopt.s
$ ld -o tocopt -melf64ppc tocopt.o
tocopt.o: In function `_start':
(.text+0x14): toc optimization is not supported for 0x3fa00000 instruction.
(.text+0x34): toc optimization is not supported for 0x3fa00000 instruction.
$
and:
$ as -o jal-global-multi-overflow.o jal-global-multi-overflow.s
$ ld -Ttext 0x1fffd000 -e foo -o jal-global-multi-overflow jal-global-multi-overflow.o
jal-global-multi-overflow.o: In function `foo':
(.text+0x2000): relocation truncated to fit: R_MIPS_26 against `bar'
(.text+0x2008): relocation truncated to fit: R_MIPS_26 against `bar'
jal-global-multi-overflow.o: In function `bar':
(.text+0x4000): relocation truncated to fit: R_MIPS_26 against `foo'
(.text+0x4008): relocation truncated to fit: R_MIPS_26 against `foo'
$
respectively instead. Adjust the test suite accordingly.

PowerPC/BFD: Convert `%P: %H:' to `%H:' in error messages
Remove an inconsistency in BFD linker error messages across the PowerPC
backends, where in the presence of line information the `%P: %H:' format
sequence makes the first error message produced for any given function
different from subsequent ones.
Taking the `ld/testsuite/ld-powerpc/tocopt7.s' test case source as an
example and the `powerpc-linux' target we have:
$ as -gdwarf2 -o tocopt.o -a64 tocopt.s
$ ld -o tocopt -melf64ppc tocopt.o
ld: tocopt.o: In function `_start':
tocopt.s:35:(.text+0x14): toc optimization is not supported for 0x3fa00000 instruction.
ld: tocopt.s:49:(.text+0x34): toc optimization is not supported for 0x3fa00000 instruction.
$
where the first error message does not have the source file name
prefixed with the linker program executable's name, i.e. `ld:', whereas
the second error message does, as would any subsequent.
This is because with a multiple-line error message such as `%H' produces
`%P' only prints the program executable's name on the first line and not
any later ones. Also the PowerPC backend is the only part of BFD which
uses `%P' along with one of the clever `%C', `%D', `%G', `%H' format
specifiers. And last but not least this breaks a GNU Coding Standard's
requirement that error messages from compilers should look like this:
source-file-name:lineno: message
also quoted in `vfinfo' code handling these specifiers.
Convert `%P: %H:' to `%H:' in error messages across the PowerPC backends
then, yielding:
$ as -gdwarf2 -o tocopt.o -a64 tocopt.s
$ ld -o tocopt -melf64ppc tocopt.o
tocopt.o: In function `_start':
tocopt.s:35:(.text+0x14): toc optimization is not supported for 0x3fa00000 instruction.
tocopt.s:49:(.text+0x34): toc optimization is not supported for 0x3fa00000 instruction.
$
instead, making it consistent and matching the GNU Coding Standard's
requirement.

btrace: Use binary search to find instruction.
Currently, btrace_find_insn_by_number will iterate over all function call
segments to find the one that contains the needed instruction. This linear
search is too slow for the upcoming Python bindings that will use this
function to access instructions. This patch introduces a vector in struct
btrace_thread_info that holds pointers to all recorded function segments and
allows to use binary search.
The proper solution is to turn the underlying tree into a vector of objects
and use indices for access. This requires more work. A patch set is
currently being worked on and will be published later.

btrace: preserve call stack on function switch
On 64-bit FC25, the _dl_runtime_resolve function uses a conditional branch to
'call' a particular variant optimized for that system:
(gdb) disas _dl_runtime_resolve_avx_opt
Dump of assembler code for function _dl_runtime_resolve_avx_opt:
0x00007ffff7deeb60 <+0>: push %rax
0x00007ffff7deeb61 <+1>: push %rcx
0x00007ffff7deeb62 <+2>: push %rdx
0x00007ffff7deeb63 <+3>: mov $0x1,%ecx
0x00007ffff7deeb68 <+8>: xgetbv

0x00007ffff7deeb75 <+21>: bnd je 0x7ffff7def4a0 <_dl_runtime_resolve_sse_vex>
End of assembler dump.
When computing the function-level trace, btrace treats this as a switch from
_dl_runtime_resolve_avx_opt to _dl_runtime_resolve_sse_vex. We know that we
switched functions but we can't really say in which caller/callee relationship
those two functions are.
In addition to preserving the indentaion level, also preserve the caller
information. This is a heuristic since we don't really know. But at least in
this case, this seems to be the right thing to do.
This fixes a fail in gdb.btrace/rn-dl-bind.exp on 64-bit FC25.

Fix gdb.linespec/explicit.exp
This patch addresses timeout failures i noticed while testing aarch64-elf.
FAIL: gdb.linespec/explicit.exp: complete unique function name (timeout)
FAIL: gdb.linespec/explicit.exp: complete non-unique function name (timeout)
FAIL: gdb.linespec/explicit.exp: complete non-existant function name (timeout)
FAIL: gdb.linespec/explicit.exp: complete unique file name (timeout)
FAIL: gdb.linespec/explicit.exp: complete non-unique file name (timeout)
The timeouts were caused by an attempt to match a bell character (x07) that
doesn't show up on my particular test setup.
The bell character is output whenever one tries to complete a pattern and there
are multiple possible matches. When there is only one possible match, GDB will
complete the input pattern without outputting the bell character.
The reason for the discrepancy in this test's behavior is due to the use of
"main" for a unique name test.
On glibc-based systems, GDB may notice the "main_arena" symbol, which is
a data global part of glibc's malloc implementation. Therefore a bell character
will be output because we have a couple possible completion matches.
GDB should not be outputting such a data symbol as a possible match, but this
problem may/will be addressed in a future change and is besides the point of
this particular change.
On systems that are not based on glibc, GDB will not see any other possible
matches for completing "main", so there will be no bell characters.
The use of main is a bit fragile though, so the patch adds a new local function
with a name that has a greater chance of being unique and adjusts the test to
iuse it.
I've also added the regular expression switch (-re) to all the
gdb_test_multiple calls that were missing it. Hopefully this will reduce the
chances of someone wasting time trying to match a regular expression (a much
more common use case) when, in reality, the pattern is supposed to be matched
literally.

Make gdb.arch/i386-biarch-core.exp more robust
This test attempts to load a x86 core file no matter what target
architectures the tested GDB supports. If GDB doesn't know how to handle
a i386 target, it is very likely the core file will not be recognized.
In this case we should still attempt to load a core file to make sure GDB
doesn't crash or throws an internal error. But we should not proceed to
try to read memory unconditionally.
This patch makes the test check for proper i386 arch support in GDB and bails
out if i386 is not supported and the core file format is not recognized.
This addresses the spurious aarch64-elf failures i'm seeing for this test.

Do not send queries on secondary UIs
This is a follow-up to
https://sourceware.org/ml/gdb-patches/2017-02/msg00261.html
This patch restricts queries to the main UI, which allows to avoid two
different problems.
The first one is that GDB is issuing queries on secondary MI channels
for which a TTY is allocated. The second one is that GDB is not able to
handle queries on two (CLI) UIs simultaneously. Restricting queries to
the main UI allows to bypass these two problems.
More details on how/why these two problems happen:
1. Queries on secondary MI UI
The current criterion to decide if we should query the user is whether
the input stream is a TTY. The original way to start GDB in MI mode
from a front-end was to create a subprocess with pipes to its
stdin/stdout. In this case, the input was considered non-interactive
and queries were auto-answered. Now that front-ends can create the MI
channel as a separate UI connected to a dedicated TTY, GDB now
considers this input stream as interactive and sends queries to it.
By restricting queries to the main UI, we make sure we never query on
the secondary MI UI.
2. Simultaneous queries
As Pedro stated it, when you have two queries on two different CLI UIs
at the same time, you end up with the following pseudo stack:
#0 gdb_readline_wrapper
#1 defaulted_query // for UI #2
#2 handle_command
#3 execute_command ("handle SIGTRAP" ....
#4 stdin_event_handler // input on UI #2
#5 gdb_do_one_event
#7 gdb_readline_wrapper
#8 defaulted_query // for UI #1
#9 handle_command
#10 execute_command ("handle SIGINT" ....
#11 stdin_event_handler // input on UI #1
#12 gdb_do_one_event
#13 gdb_readline_wrapper
trying to answer the query on UI #1 will therefore answer for UI #2.
By restricting the queries to the main UI, we ensure that there will
never be more than one pending query, since you can't have two queries
on a UI at the same time.
I added a snippet to gdb.base/new-ui.exp to verify that we get a query
on the main UI, but that we don't on the secondary one (or, more
precisely, that it gets auto-answered).
gdb/ChangeLog:
* utils.c (defaulted_query): Don't query on secondary UIs.
gdb/testsuite/ChangeLog:
* gdb.base/new-ui.exp (do_test): Test queries behavior on main

Remove some ui_out-related cleanups from Python
This patch introduces a bit of infrastructure -- namely, a minimal
std::optional analogue called gdb::optional, and an RAII template
class that works like make_cleanup_ui_out_tuple_begin_end or
make_cleanup_ui_out_list_begin_end -- and then uses these in the
Python code. This removes a number of cleanups and generally
simplifies this code.
std::optional is only available in C++17. Normally I would have had
this code check __cplusplus, but my gcc apparently isn't new enough to
find <optional>, even with -std=c++1z; so, because I could not test
it, the patch does not do this.

I did a bit of archaelogy, and found that back in 4a8f6654 (2003), it
was also called in another place, to decide whether to print the CLI
prompt.
AFAICS, that condition is always false today, making that if/then
block always dead code. If we remove that code, then there are no
interp_quiet_p uses left in the tree, so we can remove it all.
There are two paths that lead to interp_set calls:
#1 - When installing the top level interpreter. In this case,
FIRST_TIME is true.
#2 - In interpreter_exec_cmd. In this case, the interpreter is always
set quiet before interp_set is called.
Grepping a gdb.log of an x86_64 GNU/Linux run for "Switching to
interpreter" (before this patch) doesn't find any hits.
I suspect the intention of this message was to support something like
a "set interpreter ..." command that would change the interpreter
permanently. But there's no such command.
Tested on x86_64 Fedora 23.
gdb/ChangeLog:
2017-02-08 Pedro Alves <palves@redhat.com>
* interps.c (interp::interp): Remove reference to quiet_p.
(interp_set): Make static. Remove dead "Switching to" output
code.
(interp_quiet_p, interp_set_quiet): Delete.
(interpreter_exec_cmd): Don't set the interpreter quiet.
* interps.h (interp_quiet_p): Make static.
(class interp) <quiet_p>: Remove field

Command abbreviation in define
When defining a new macro, "command" is not recognized as an alias for
"commands":
(gdb) define breakmain
Type commands for definition of "breakmain".
End with a line saying just "end".
>break main
>command
>echo "IN MAIN\n"
>end
(gdb)
There is a special case for while-stepping, where 'ws' and 'stepping' are
recognized explicitely. Instead of adding more special cases, this change
uses cli-decode.
gdb/ChangeLog:
* cli/cli-decode.c (find_command_name_length): Make it extern.
* cli/cli-decode.h (find_command_name_length): Declare.
* cli/cli-script.c (command_name_equals, line_first_arg):
New functions.
(process_next_line): Use cli-decode to parse command names.
(build_command_line): Make args a constant pointer.
gdb/testsuite/ChangeLog:
* gdb.base/define.exp: Add test for command abbreviations
in define.

Command names: make them case sensitive
Case-insensitive search for command names is an obscure undocumented
feature, which seems to be unused, is not tested and not quite
consistent. Remove it.
gdb/ChangeLog:
* cli-decode.c (lookup_cmd_1, lookup_cmd_composition):
Remove case-insensitive search.
