With the addition of section16 tests we have multiple tests
advertising themselves as "mbind sections" and "mbind section
contents". This patch fixes that, and fails on quite a few targets
that force an OSABI value. It's a pain specifying all the relevant
arm targets on an xfail line, so I wrote supports_gnu_osabi.

Clang's integrated assembler supports multiple section with the same
name:
.section .text,"ax",@progbits,unique,1
nop
.section .text,"ax",@progbits,unique,2
nop
"unique,N" assigns the number, N, as the section ID, to a section. The
valid values of the section ID are between 0 and 4294967295. It can be
used to distinguish different sections with the same section name.
This is useful with -fno-unique-section-names -ffunction-sections.
-ffunction-sections by default generates .text.foo, .text.bar, etc.
Using the same string can save lots of space in .strtab.
This patch adds section_id to bfd_section and reuses the linker
internal bit in BFD section flags, SEC_LINKER_CREATED, for assmebler
internal use to mark valid section_id. It also updates objdump to
compare section pointers if 2 sections comes from the same file since
2 different sections can have the same section name.

Commit 9e7028aa1e ("PowerPC64 __tls_get_addr_desc") introduced a use
of @option which apparently newer makeinfo tolerates, but older ones
reject. Drop the unnecessary (a per all other uses of @option) blank.
This provides a linker generated __tls_get_addr_desc wrapper function
preserving registers around a __tls_get_addr call. The idea being to
support __tls_get_addr_desc without requiring a glibc update.

This implements register saving and restoring in the __tls_get_addr
call stub, so that when glibc supports the optimized tls call stub gcc
can generate code that assumes only r0, r12 and of course r3 are
changed on a __tls_get_addr call. When gcc expects __tls_get_addr
calls to preserve registers the call will be to __tls_get_addr_desc,
which will be translated by the linker to a call to __tls_get_addr_opt.

This modifies the special __tls_get_addr stub that checks for a
tlsdesc style __tls_index entry and returns early. Not using r11
isn't much benefit at the moment but a followup patch will preserve
regs around the first call to __tls_get_addr when the __tls_index
entry isn't yet set up for an early return.

Function symbols of course don't normally want .dynbss copies but
with some old versions of gcc they are needed to copy the function
descriptor. This patch restricts the cases where they are useful to
compilers using dot-symbols, and enables the warning regardless of

This fixes PR 25210 by specifying the the correct ELF class for AArch64 stubs.
After doing this the stub section starts behaving like a normal object file
loaded from disk. That is SEC_LINKER_CREATED causes us to have to write the
section manually.
This flag was added as a fix for PR 24753. I believe that
fix to still be correct as linker created sections don't have a size on disk
and it fixes the Arm bootstrap regression. But in this case specifying the
correct section class also makes the stub section not be considered by
compress.c.
So I'm partially revert this change so that we don't have to manage the section
manually as implied by SEC_LINKER_CREATED.

I reckon it's quite OK to write &p->field in C when p might be NULL,
and lots of old C programmers probably agree with me. However, ubsan
disagrees and so do some people I respect. I suspect C++ influence is
to blame for the ubsan behaviour. See
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92634. So far no one has
educated me as to why I'm wrong to claim that there isn't anything in
the C standard to say that p->field is always (*p).field. Note 79
doesn't quite do that because it doesn't cover null pointers. If
there was such an equivalence then you could claim &p->field has a
null pointer reference when p is NULL, even though no C compiler would
ever dereference p.
Anyway, to silence ubsan I'm going to apply the following though I
prefer to avoid casts when possible. And I'm using (void *)
deliberately because this is C, not C++!

Changing objdump disassembly output like this always requires some
testsuite changes, with the avr and x64_64 changes simply due to
picking up better symbols, the whole point of the patch.
The mips changes are due to mips-sgi-irix changing STT_NOTYPE symbols
to STT_OBJECT, which objdump now chooses in preference to script
symbols. The problem is that objdump looks at the first symbol in the
section being disassembled, and if object type, just dumps out bytes
rather than disassembling. This results in new failures:
FAIL: JAL overflow 2
FAIL: undefined weak symbol overflow
FAIL: undefined weak symbol overflow (n32)
FAIL: undefined weak symbol overflow (n64)
So for mips-sgi-irix function symbols really do need to be function
type. I fixed a few more than just the required minimum to avoid the
above test fails.

mips-sgi-irix gas emits STT_OBJECT symbols where other assemblers
would use STT_NOTYPE. See mips_frob_symbol in gas/config/tc-mips.c.
Also, the section of some dynamic symbols is set to SHN_MIPS_TEXT or
SHN_MIPS_DATA. See _bfd_mips_elf_finish_dynamic_symbol in

* testsuite/ld-elf/pr21233-l.sd: Accept OBJECT for type and
PRC for section of symbols.
* testsuite/ld-elf/pr23591.d: Likewise.
* testsuite/ld-elf/provide-hidden-s.nd: Likewise.
* testsuite/ld-mips-elf/start.s: Make symbols function type.
* testsuite/ld-mips-elf/hash2.d: Adjust. Don't xfail irix.
This adds an alternative to using #... in dump files, useful where we
only want to allow specific extra output. DW_CFA_nop in CIEs and FDEs
to pad out to required alignment (larger for 64-bit than 32-bit) is
an example where these optional match patterns are useful.
binutils/
* testsuite/lib/binutils-common.exp (regexp_diff): Support #?REGEXP.
ld/
* testsuite/ld-elf/eh4.d: Match optional padding DW_CFA_nop in FDEs.
* testsuite/ld-elf/eh5.d: Likewise, and extra CIEs emitted on
embedded targets.
