Fix PR binutils/33186 - No SFrame dump if section name is not .sframe
When the section name is not ".sframe", ensure that readelf and objdump
are able to dump a section of type SHT_GNU_SFRAME and not fail if the
user specifies the new section name.
For objdump, in dump_dwarf_section (), use the match string of ".sframe"
to find the corresponding debug_displays[] item for SFrame section.
Doing this ensures that any call to dump_dwarf_section () with the
section pointing to the SFrame section (with name possibly different
from ".sframe") will successfully dump the SFrame section.
If the SFrame section is named anything but ".sframe", and user does not
specify the name of the SFrame section either, the documented behaviour
is that the default section name is assumed to be ".sframe". So the
following (albeit counter intuitive) is expected at this time:
$ readelf -S sort | grep sframe
[NN] .sframe2 GNU_SFRAME 0000000000NNNNNN 0000NNNN
(Note section name .sframe2).
$ objdump --sframe sort
sort: file format elf64-x86-64
No .sframe section present
(Similarly for readelf as well).
For objdump, set dump_sframe_section_name to ".sframe" if user specifies
no section name. In the error checking done in dump_sframe_section, add
the case when user specifies a valid section name but one that does not
contain SFrame section data. For sections generated with Binutils >=
2.45, this can be checked with section type of SHT_GNU_SFRAME.
Previously these sections were SHT_PROGBITS with name ".sframe".
Similar changes in readelf.
Add a test each for objdump and readelf to dump a renamed section. Use
gas_sframe_check to limit the execution of these tests only when a gas
supporting SFrame format is present.

strip: Add GCC LTO IR support
added "-R .gnu.lto_.*" to strip to remove all GCC LTO sections. When
"-R .gnu.lto_.*" is used, the plugin target is ignored so that all LTO
sections are stripped as the regular sections. It works for the slim
GCC LTO IR since the GCC LTO IR is stored in the regular sections. When
the plugin target is ignored, the GCC LTO IR can be recognized as the
normal object files. But it doesn't work for the slim LLVM IR which
is stored in a standalone file.
1. Add bfd_check_format_matches_lto and bfd_check_format_lto to take an
argument, lto_sections_removed, to indicate if all LTO sections should
be removed.
2. Update strip to always enable the plugin target so that the plugin
target is enabled when checking for bfd_archive.
3. Update strip to ignore the plugin target for bfd_object when all LTO
sections should be removed. If the object is unknown, copy it as an
unknown file without any messages.
4. Treat the "-R .llvm.lto" strip option as removing all LTO sections.

Like ELF for all symbols, COFF can record size for at least function
ones. Use that - if available - in preference to the distance-to-next-
symbol heuristic.
To be able to use the new test there, make TI C54x follow TI C4x in
providing .sdef to cover for .def already having different meaning.
There's no reason to limit this to just ELF. TI C30 and Z8k don't encode
section alignment in the section entries though (which can't be quite
right, or there would need to be another means by which to express
alignment needs), so --set-section-alignment simply has no effect there.
PR binutils/32732
The --set-section-alignment option is what ought to be used on object
files; --section-alignment should be affecting PE binaries only, and
only the value stored in the header. Sections don't individually have
alignment recorded there; see 6f8f6017a0 ("PR27567, Linking PE files
adds alignment section flags to executables").
Undo the core part of 121a3f4b4f ("Update objcopy's
--section-alignment option so that it sets the alignment flag on..."),
which includes removing the testcase again, while leaving all secondary
changes in place. (Note that the testcase did fail anyway for
i?86-interix, with objdump saying "option -P/--private not supported by
this file".)
The output file could be created before the input is gathered by tail,
erasing the later before it's being proceeded.
This happened on rare cases when performing remote tests on
Ubuntu 24.04.
Turns out the return value of parse_loongarch_dis_option acts as an
error code, and previously the function always signified failure with
a non-zero return value, making only the first disassembly option get
to take effect.
Fix by adding the missing `return 0`'s to the two success code paths.

This allows you to specify a run_dump_test warning that may or may not
be present using
warning: (warning_text_goes_here)?
ie. the regexp matches an empty string.
ar is supposed to make archives containing any sort of file, and it
generally does that. It also tries to make archives suited to target
object files stored. Some targets have peculiar archives.
In one particular case we get into trouble trying to suit archives to
object files: where the target object file is recognised but that
target doesn't happen to support archives, and the default target has
a special archive format. For example, we'll get failures on
rs6000-aix if trying to add tekhex objects to a new archive. What
happens in that the tekhex object is recognised and its target vector
used to create an empty archive, ie. with _bfd_generic_mkarchive and
_bfd_write_archive_contents. An attempt is then made to open the
newly created archive. The tekhex target vector does not have a
check_format function to recognise generic archives, nor as it happens
do any of the xcoff or other targets built for rs6000-aix.
It seems to me the simplest fix is to not use any target vector to
create archives where that vector can't also recognise them. That's
what this patch does, and to reinforce that I've removed target vector
support for creating empty archives from such targets.

The noxfail option is useful in situations like pr23658-1e which
fails on all microblaze ELF targets except microblaze-linux. This was
possible to handle by writing a small proc and use that as an xfail

this is simpler. The patch also fixes some other FAILs and XPASSes of

While for executables properly aligning sections within the file can be
quite relevant, the same is of pretty little importance for relocatable

cases as a cap to the alignment put in place.

unimportant objcopy memory leaks, but expanded into a larger patch
when I was annoyed by the awkwardness of passing data when using

Files named *.0 are somewhat odd for testsuite expectations. Rename the
one such file to *.r with a suitable base name suffix, and have its
sibling follow suit in this latter regard.
Implement a helper to construct a relative path between two locations in
the filesystem, for example to make a path from the source to the object
directory for the case where a tool has been set up to look at a given
path and there is a need to point it elsewhere, but an absolute path
will not work. The helper works on normalized paths internally, so the
result is correct even in the presence of symlinks as intermediate path
components.
So given "/path/to/src/gas/testsuite/gas/all" as the FROM argument and
then "/path/to/obj/gas/testsuite/tmpdir/none.s" as the TO argument the
helper will return "../../../../../obj/gas/testsuite/tmpdir/none.s" in
the absence of symlinks.
