This functions was changed to return an int in commit ece5ef60797f but
since bfd_boolean was an int typedef I lazily left all the ELF
relocate_section functions as returning bfd_boolean, except the SPU
one. In order to use _Bool or bool in place of bfd_boolean we need to
be fussy about the return types.

Undefined weak symbols with non-default visibility are seen as local
by SYMBOL_REFERENCES_LOCAL. This stops a got indirect to relative
optimisation for them, so that pies and dlls don't get non-zero values

but I thought it best not to allow it there too.

Calling non-pcrel functions from pcrel code requires a stub to set up

The save of r2 in __glink_PLTresolve is the culprit. Remove it,

should not be used with power10 pc-relative code that makes tail

Some of the powerpc64 code editing functions are better run after
dynamic symbols have stabilised in order to make proper decisions
based on SYMBOL_REFERENCES_LOCAL. The dynamic symbols are processed
early in bfd_elf_size_dynamic_sections, before the backend
always_size_sections function is called.
One function, ppc64_elf_tls_setup must run before
bfd_elf_size_dynamic_sections because it changes dynamic symbols.
ppc64_elf_edit_opd and ppc64_elf_inline_plt can run early or late, I
think. ppc64_elf_tls_optimize and ppc64_elf_edit_toc are better run
later.
So this patch arranges to call some edit functions later via
always_size_sections.

ppc64 ld optimises sequences like the following
addis 3,13,wot@tprel@ha
lwz 3,wot@tprel@l(3)
to
nop
lwz 3,wot@tprel(13)
when "wot" is located near enough to the thread pointer.
However, the ABI doesn't require that R_PPC64_TPREL16_HA always be on
an addis rt,13,imm instruction, and while ld checked for that on the
high-part instruction it didn't disable the optimisation on the
low-part instruction. This patch fixes that problem, disabling the
tprel optimisation globally if high-part instructions don't pass
sanity checks. The optimisation is also enabled for ppc32, where
before ld.bfd had the code in the wrong place and ld.gold had it in a

as might be seen in a cpu-optimized library using ifuncs to select
functions optimized for a given cpu. Using -Wl,--no-power10-stubs
isn't that good in this situation since non-power10 notoc stubs are
slower and larger than the power10 variants, which you'd like to use
on power10 code paths.
With this change, power10 pc-relative code that makes calls marked
@notoc uses power10 stubs if stubs are necessary, and other calls use
non-power10 instructions in stubs. This will mean that if gcc is
generating code for -mcpu=power10 but with pc-rel disabled then you'll
get the older stubs even on power10 (unless you force with
-Wl,--power10-stubs). That shouldn't be too big a problem: stubs that
use r2 are reasonable. It's just the ones that set up addressing
using "mflr 12; bcl 20,31,.+4; mflr 11; mtlr 12" that should be
avoided if possible.

For ppc64 I set flags when recording the dynamic relocation rather
than when allocating space. That allows you to distinguish three
cases:
1) The dynamic ifunc relocation is in an executable and will always be
to an ifunc resolver in the executable.
2) The dynamic ifunc relocation is in a shared library which provides
an ifunc resolver, but that may be overridden at runtime to use a
resolver in another binary.
3) The dynamic ifunc relocation is not to a locally defined ifunc
resolver.
Case (3) won't cause a segfault trying to run resolver code that is
non-exec on older glibc.
I made case (1) an error for ppc64, but since newer glibc ld.so does
allow running ifunc resolvers when segments are writable I suppose I
should downgrade that to a warning like case (2).

Don't do anything special with non-loaded, non-alloced sections.
In particular, any relocs in such sections should not affect GOT
and PLT reference counting (ie. we don't allow them to create GOT
or PLT entries), there's no possibility or desire to optimize TLS
relocs, and there's not much point in propagating relocs to shared
libs that the dynamic linker won't relocate.
Since check_relocs is no longer called on non-loaded, non-alloced
sections, remove SEC_ALLOC check. Resolve relocation in debug section
against symbol defined in shared library to 0.

I can't see any reason why ELFv2 should create a PLT entry for ifuncs
referenced by GOT relocs as long as the GOT entry remains. The GOT
entry ought to be resolved by ld.so to the value returned by the ifunc
resolver, or if there is global entry stub created for some other
reason, by the linker to the stub address.
* elf64-ppc.c (ppc64_elf_check_relocs): Don't create plt entries
for GOT relocs against ifuncs.
|

When the symbol referenced by a GOT reloc is an ifunc, we can't
optimise away the GOT indirection. Well, we can, but only if a global
entry stub is created with the ifunc symbol redefined to the stub.
But that results in slower code and an indirection via the PLT so
there isn't much to like about that solution.

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 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.
bfd/
* elf64-ppc.c (struct ppc_link_hash_table): Add tga_group.
(ppc64_elf_archive_symbol_lookup): Extract __tls_get_addr_opt for
__tls_get_addr_desc.
(ppc64_elf_size_stubs): Add section for linker generated
__tls_get_addr_desc wrapper function. Loop at least once if
generating this function.
(emit_tga_desc, emit_tga_desc_eh_frame): New functions.
(ppc64_elf_build_stubs): Generate __tls_get_addr_desc.

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.
