This patch adds support for TLS relocation targeting C_HIDEXT symbols.
In gas, TLS relocations, except R_TLSM and R_TLMSL, must keep the value
of their target symbol.
In ld, it simply ensures that internal TLS symbols are added to the
linker hash table for xcoff_reloc_type_tls.
It also improves the tests made by both.
bfd/ChangeLog:
* coff-rs6000.c (xcoff_howto_table): Fix name of R_TLSML.
(xcoff_reloc_type_tls): Replace the error when h is NULL by
an assert.
(xcoff_complain_overflow_unsigned_func): Adjust comments.
* coff64-rs6000.c (xcoff64_howto_table): Fix name of R_TLSML.

hash table.

The Darwin code uses unfiltered output liberally. This patch changes
this code to send some output to gdb_stdlog (in some cases via the use
of debug_prefixed_printf_cond_nofunc), or to gdb_stderr, or to simply
switch to filtered output.
Note that I didn't switch inferior_debug to use
debug_prefixed_printf_cond_nofunc, because that would affect the
output by removing the information about the inferior. I wasn't sure
if this was important or not, so I left it in.
v2 of this patch uses warning rather than prints to gdb_stderr, and
removes some trailing whitespace.
I can't compile this patch, so it's "best effort".
While testing on GNU/Hurd (i386) I noticed that GDB crashes when an
inferior exits, with this error:
inferior.c:293: internal-error: inferior* find_inferior_pid(process_stratum_target*, int): Assertion `pid != 0' failed.
The problem appears to be in gnu_nat_target::wait.
We always set inferior_ptid to null_ptid before calling target_wait,
this has been the case since the multi-target changes were made to GDB
in commit:
commit 5b6d1e4fa4
Date: Fri Jan 10 20:06:08 2020 +0000
Multi-target support
With follow up changes in commit:
commit 24ed6739b6
Date: Thu Jan 30 14:35:40 2020 +0000
gdb/remote: Restore support for 'S' stop reply packet
Unfortunately, the GNU/Hurd target is still relying on the value of
inferior_ptid in the case where an inferior exits - we return the
value of inferior_ptid as the pid of the process that exited. This
was fine in the single target world, where inferior_ptid identified
the one running inferior, but this is no longer good enough.
Instead, we should return a ptid containing the pid of the process
that exited, as obtained from the wait event, and this is what this
commit does.
I've not run the full testsuite on GNU/Hurd as there appear to be lots
of other issues with this target that makes running the full testsuite
very painful, but I think this looks like a small easy improvement.
This patch adds information about _sigsys structure from newer
kernels, so that $_siginfo decoding can show information about

DT_RELR encodes consecutive R_*_RELATIVE relocations in GOT (the global
offset table) and data sections in a compact format:
https://groups.google.com/g/generic-abi/c/bX460iggiKg
On some targets, R_*_RELATIVE relocations are counted and the GOT offsets
are allocated when setting the dynamic section sizes after seeing all
relocations. R_*_RELATIVE relocations are generated while relocating
sections after section layout has been finalized.
To prepare for DT_RELR implementation on these targets, extract
_bfd_elf_link_iterate_on_relocs from _bfd_elf_link_check_relocs so
that a backend can scan relocations in elf_backend_always_size_sections
For x86 targets, the old check_relocs is renamed to scan_relocs and a
new check_relocs is added to chek input sections and create dynamic
relocation sections so that they will be mapped to output sections.
scan_relocs is now called from elf_backend_always_size_sections.
Since relocations are scanned after __start, __stop, .startof. and
.sizeof. symbols have been finalized on x86, __[start|stop]_SECNAME for
--gc-sections -z start-stop-gc are now zero when all SECNAME sections
been garbage collected. This is no need for elf_x86_start_stop_gc_p.

This is due to an erroneous explicit test name. This explicit test name
also happens to be useless (at least it would have been if it was
correct) since it only repeats the command, so just remove the explicit
test name and let the command be used as default test name. Also remove
explicit test name at another location in the file since it also just
repeat the command.

Tested on x86_64-linux.
There is a expect support library in the source tree designed to help
developers test the auto-completion capabilities of GDB.
One of the functions is test_gdb_complete_unique_re. It is used
(usually indirectly via test_gdb_complete_unique) to test that a given
input line is completed as a given output line. The test checks for two
ways to do the completion: using tab-completion, or using the
'complete' command. To do this, calls to two dedicated functions are
performed. If we omit few details, we can consider that a call to
test_gdb_complete_unique $input $expected
is equivalent to the two following calls:
test_gdb_complete_tab_unique $input $expected
test_gdb_complete_cmd_unique $input $expected
When using the tab-completion, everything works as expected, but some
care must be taken when using the 'complete' command if the given input
has leading whitespaces. In such situation, the output of the
'complete' command will drop the leading whitespaces.
The current approach is that in such situation, the input and expected
outputs are right trimmed (i.e. all leading whitespaces are removed)
when performing the command completion check.
This means that the following call:
test_gdb_complete_unique " $input" " $expected"
is almost equivalent to (again, omitting few details and arguments):
test_gdb_complete_tab_unique " $input" " $expected"
test_gdb_complete_cmd_unique "$input" "$expected"
This approach comes with a problem that we encounter when running the
tests in complete-empty.exp. When doing so, we have:
Running .../gdb/testsuite/gdb.base/complete-empty.exp ...
DUPLICATE: gdb.base/complete-empty.exp: empty-input-line: cmd complete ""
This is because the test file does something like:
test_gdb_complete_unique "" "!" " " 1
test_gdb_complete_unique " " " !" " " 1¬
which, if we do the substitution introduced above is equivalent to:
test_gdb_complete_tab_unique "" "!"
test_gdb_complete_cmd_unique "" "!"
test_gdb_complete_tab_unique " " " !"
test_gdb_complete_cmd_unique "" "!"
We see that the lines 2 and 4 are now the same, and for this reason the
testing framework complains about DUPLICATE test names.
To fix that, this commit proposes that instead of left trimming both
input and expected outputs, only the expected output is trimmed.
Care must be taken in the case the completion gives more possibilities
than allowed by the max-completions setting. In this case, the input
will be repeated in the output in its left trimmed version. This commit
also ensures that this is taken care of.
With this commit, the gdb.base/complete-empty.exp still passes all its
tests but does not report the DUPLICATE anymore.

various decimal floating point types with a loop to programmatically
generate all the combinations. This removes the need to eyeball for all
suffixes, which lead to the original duplication.
Also add a lot more combinations, testing all comparison operators
comprehensively. The result is 262 unique tests vs 104 before this
patch.

When running the testsuite I have:

This is due to the fact that multiple successive instances of

Fix by using 'pass $gdb_test_name', given that the gdb_test_name is set

While fixing this, this patch refactors all occurrences of the following
pattern:
set cmd foo
gdb_test_multiple $cmd $cmd {
-re ... {
pass $cmd

gdb_test_multiple foo "" {

Building on the previous commit, this makes use of a trailing @ to
split long @deffn lines in the guile.texi source file. This splitting
doesn't change how the document is laid out by texinfo.
I have also wrapped keyword and argument name pairs in @w{...} to
prevent line breaks appearing between the two. I've currently only
done this for the longer @deffn lines, where a line break is
possible. This makes the @deffn lines much nicer to read in the
generated pdf.
