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.
* xcofflink.c (xcoff_link_add_symbols_to_hash_table): New

hash table.

XCOFF archives use a bi-directional linked list for file members. So
one member points to both the previous member and the next member.
Members may not be sequentially ordered in the file. This of course
is over-engineered nonsense and an attractive target for fuzzers.
(There is even a free list of members!) The testcase in PR28423 is an
XCOFF archive with one member pointing to itself, which results in
lots of bad behaviour. For example, "ar t" never terminates.
The use-after-free with "objdump -r" happens like this: The first
archive element is opened, its symbols are read and "canonicalized"
for objdump, then relocations are read and printed. Those relocations
use the canonicalized symbols, and also happen to be cached by the
coff bfd backend support. objdump frees the symbols. The next
archive element is then opened. This must be done before the first
element is closed, because finding the next element uses data held in
the currect element. Unfortunately the next element happens to be the
original, so we aren't opening, we're reopening a bfd which has cached
data. When the relocations are printed they use the cached copy
containing references to the freed canonical symbols.
This patch adds a little sanity checking to the XCOFF "open next
archive file" support, so that it rejects archive members pointing at
themselves. That is sufficient to cure this problem. Anything more
is overkill. If someone deliberately fuzzes an XCOFF archive with an
element loop then reports an "ar" bug when it runs forever, they will
find their bug report closed WONTFIX.

Add support for TLS in XCOFF. Amongst the things done by this commit:
- Update XCOFF auxialiary header to match new version and allow TLS
sections.
- Add TLS sections (.tdata and .tbss) support in gas and ld.
- Add support for the TLS relocations in gas and ld.
Two different types BFD_RELOC are created for PPC and PPC64 as
the size is a pointer, thus distinct in 32 or 64bit.
The addresses given by ld to .tdata and .tbss is a bit special. In
XCOFF, these addresses are actually offsets from the TLS pointer
computed at runtime. AIX assembly and linker does the same. In
top of that, the .tdata must be before .data (this is mandatory for AIX
loader). Thus, the aix ld script is recomputing "." before .data to restore
its original value. There might be a simpler way, but this one is working.
Optimisation linked to TLS relocations aren't yet implemented.

Implement support for largetoc on XCOFF.
R_TOCU and R_TOCL are referenced by the new BFD defines:
BFD_RELOC_PPC_TOC16_HI and BFD_RELOC_PPC_TOC16_LO.
A new toc storage class is added XMC_TE.
In order to correctly handle R_TOCU, the logic behind
xcoff_reloc_type_toc is changed to compute the whole TOC offset
instead of just the difference between the "link" offset and the
"assembly" offset.
In gas, add a function to transform addis format used by AIX
"addis RT, D(RA)" into the ELF format "addis RT, RA, SI".

Since the last time AIX HOWTO table was modified, IBM has now
released an official documentation about XCOFF relocations.
This commit corrects the wrong ones and add some missing.
For now, the "custom" relocations made for xcoff_rtype2howto have
been kept.
The new relocations are still set as EMPTY_HOWTO because they will
be implemented in later commits.
In xcoff[64]_ppc_relocate_section, instead of recreating howto
from scratch, it's better to use the existing howto from the
table and fixing it according to r_size field.

For ELF targets, section symbols are required only for relocations.
With -ffunction-sections -fdata-sections, there can be many unused
section symbols. Sizes of libstdc++.a on Linux/x86-64 in GCC 11 are
With unused section symbols : 39411698 bytes
Without unused section symbols: 39227002 bytes
The unused section symbols in libstdc++.a occupy more than 180 KB.
Add BSF_SECTION_SYM_USED to indicate if a section symbol should be
included in the symbol table. The BSF_SECTION_SYM_USED should be set
if the section symbol is used for relocation or the section symbol is
always included in the symbol table.
Add keep_unused_section_symbols to bfd_target to indicate if unused
section symbols should be kept. If TARGET_KEEP_UNUSED_SECTION_SYMBOLS
is defined as FALSE, unused ection symbols will be removed.
Tested on Linux/x86. Other ELF backends need to:
1. Define TARGET_KEEP_UNUSED_SECTION_SYMBOLS to FALSE.
2. Mark used section symbols in assembler backend.
3. Remove unused section symbols from expected assembler and linker
outputs.

The object_p (and archive_p, core_file_p) functions are not supposed
to have any target specific malloc'd memory attached to the bfd on
their return. This should be obvious on a failure return, but it's
also true for a successful return. The reason is that even though the
object_p recognises the file, that particular target may not be used
and thus the bfd won't be closed calling close_and_cleanup for the
target that allocated the memory.
It turns out that the object_p bfd_target* return value isn't needed.
In all cases except ld/plugin.c the target is abfd->xvec and with
ld/plugin.c the target isn't used. So this patch returns a cleanup
function from object_p instead, called in bfd_check_format_matches to
tidy the bfd before trying a different target match. The only cleanup
that does anything at this stage is the alpha-vms one.

bfd_size_type was invented a long time ago in the K&R days. Many
places in binutils ought to be using size_t instead (and there are
lots of places that use long or unsigned long that really ought to use
size_t too). Note that you can't change everything over to size_t: A
32-bit host needs a larger type than size_t to support reading and
processing of 64-bit ELF object files. This patch just tidies some
of the more obvious uses of bfd_size_type that could be size_t. There
no doubt are more lurking in the source. Incidentally, practically
all functions used for output of object files can use size_t and don't
need to worry about overflow of size expressions. If you have
something like
symcount * sizeof (void *)
when symcount is counting symbols already in memory then you know that
this expression can't overflow since the size of a symbol in memory is
larger by far than that of a pointer.

This patch uses bitfields in reloc_howto_struct, reducing its size
from 80 to 40 bytes on 64-bit hosts and from 52 to 32 bytes on 32-bit
hosts (with a 32-bit bfd_vma). I've also added a new "negate" field
rather than making the encoded "size" field do double duty as both
a size and a flag.
There was just one use of an encoded size of 8, which according to
bfd_get_reloc_size meant 16 bytes, in vms-alpha.c ALPHA_R_LINKAGE.
See git commit c3d8e071bf adding ALPHA_R_LINKAGE and git commit
8612a388f7 decoding size 8 in bfd_get_reloc_size. Since no other part
of BFD handles 16 byte relocs, I've removed that encoding and special
cased the ALPHA_R_LINKAGE size in vms-alpha.c.

There should be no difference in output for symbols defined by HIDDEN

hidden or not. This patch adds a new BFD function, bfd_link_hide_symbol,

functions. I've also renamed the stub functions to reflect their
parameters and put "error" in the name if they set bfd_error. The
latter change is important since there were quite a few uses of
bfd_false where setting bfd_error was inappropriate, for example in
elf_backend_allow_non_load_phdr and is_target_special_symbol.

GCC 8 will bring a new warning option which will detect possible
overflow and truncation on string manipulation functions. For more
details, see:
https://gcc.gnu.org/ml/gcc-patches/2017-08/msg00471.html
While compiling BFD with it, I can see one place on bfd/coff-rs6000.c
where the warning is triggered. This:
(void) strncpy (fhdr.magic, XCOFFARMAG, SXCOFFARMAG);
will not include the trailing NUL on fhdr.magic, but that's fine
because it's a magic number. The fix is trivial: just use memcpy
instead.
OK to push?
2018-02-06 Sergio Durigan Junior <sergiodj@redhat.com>
* coff-rs6000.c (xcoff_write_archive_contents_old): Use
'memcpy' instead of 'strncpy' when writing the magic number.

whitespace = indent-with-non-tab,space-before-tab,trailing-space
and I got annoyed enough seeing red in "git diff" output to fix
the problems.
