There are a number of targets that don't support thin archives (*),
and vms doesn't even support file name extensions other than .obj for
archives containing object files. This patch adjusts the testsuite
to cater for the vms restriction, and reenables testing for non-ELF
alpha targets. That adds a few alpha-dec-vms fails and one
alpha-linuxecoff fail but testsuite fails on those targets are nothing
new.

A couple of ld ifunc tests currently FAIL on 64-bit Solaris/x86:

FAIL: ld-ifunc/pr17154-x86-64
For one, the actual error is weird:
./ld-new: target elf64-x86-64 not found
failed with: <./ld-new: target elf64-x86-64 not found>, no expected output
FAIL: ld-ifunc/ifunc-10-x86-64
although ld -V does report the elf_x86_64 emulation as supported:
$ ./ld/ld-new -V
GNU ld (GNU Binutils) 2.34.50.20200328
Supported emulations:
elf_x86_64_sol2
elf_x86_64
[...]
When using ld -m elf_x86_64_sol2 instead, one of the testcases links
successfully.
However, there's no point in pursuing this: Solaris does not support
ifunc, as can be seen in <sys/elf.h>:
/*
* GNU/Linux specific symbol type not used by Solaris
*/
#define STT_GNU_IFUNC 10
and never will, given that it has symbol capabilities as solution to
effectively the same problem:
http://www.linker-aliens.org/blogs/rie/entry/symbol_capabilitie/
Therefore this patch disables ifunc testing on Solaris completely by
removing Solaris from binutils/testsuite/lib/binutils-common.exp
(supports_gnu_osabi). The ifunc part is justified above. SHF_GNU_MBIND is
in the OS-specific range and conflicts with
#define SHF_SUNW_REALLOC 0x01000000 /* internal: krtld realloc */
While the comment suggests this might be relocatable without too much
problems, the description of mbind (no formal spec AFAICS, just the
comment in the binutils patch submission) strongly suggests that this
isn't relevant to Solaris at all.
Indirectly, clearing supports_gnu_osabi on Solaris disables
supports_gnu_unique. Again, Solaris <sys/elf.h> has
/*
* GNU/Linux specific binding not used by Solaris
*/
#define STB_GNU_UNIQUE 10
so this seems the right thing to do.
Afterwards, one can remove the explicit mentions of *-*-solaris2* in
quite a number of (but not all) the ld-ifunc dump file notarget lists.
There's one fallout, though: two gas tests now XPASS because they are
xfail'ed for !supports_gnu_osabi:
XPASS: mbind sections 12
XPASS: mbind section contents 16
XPASS: mbind sections 16
XPASS: mbind section contents 16
To fix that, I've changed
#xfail: ![supports_gnu_osabi]
to notarget.

x86_64-pc-linux-gnu, and i686-pc-linux-gnu.

Last patch didn't manage to xfail spu due to clear_xfail *-*-*elf*.
Clearing *-*-*elf* dates back to a time when we had rather a lot more
setup_xfail patterns, so limiting it to hppa*-*-*elf*. Also,
mips-*-irix ought to have been mips-*-irix* and I'm having second
thoughts about xfailing mips and hiding what looks like a problem: If
the mips target is supposed to emit names for local section symbols
and does so for objcopy, why isn't it doing the same for ld? Also,
lots more mips targets would be subject to this test failing. So I'm
backing out those xfails and leaving it to someone more knowledgeable
about mips.
* testsuite/binutils-all/objcopy.exp (objcopy_test): Only
clear_xfail hppa*-*-*elf*. Revert mips xfails.
xfails spu due to a note section getting a different vma, and some
mips targets that give section symbols a name string. I added -p
for the executable test in an attempt to fix all the pe target fails,
but that doesn't preserve the date/time for some reason.
* testsuite/binutils-all/objcopy.exp (objcopy_test): Move xfails
from here to calls. Remove "m8*-*-*" entry. Don't xfail tic54x

debuginfod is a lightweight web service that indexes ELF/DWARF
debugging resources by build-id and serves them over HTTP. This patch
enables objdump and readelf to query debuginfod servers when they are
otherwise not able to find separate debug files. Binutils can be built
with debuginfod using the --with-debuginfod configure option. This
requires that libdebuginfod be installed and found at configure time.
debuginfod is packaged with elfutils, starting with version 0.178. For

The SOM backend creates BFD sections for "spaces", and "sub-spaces".
"sub-spaces" are what we normally think of as a section, "spaces"
aggregate "sub-spaces". Thus it does not really make sense to include
"spaces" for size -A since that would double count total size.
It so happens that real sections ought to have at least one of the
ALLOC and HAS_CONTENTS flags set, so this patch excludes "spaces" but
excluding BFD sections with no flags set.
