LoongArch: ld: Simplify inserting IRELATIVE relocations to .rela.dyn
Checks
Commit Message
In LoongArch, the R_LARCH_IRELATIVE relocations for local ifunc symbols are
in .rela.dyn. Before, this is done by loongarch_elf_finish_dynamic_sections.
But this function is called after elf_link_sort_relocs, it need to find a
null slot to insert IRELATIVE relocation.
Now, it is processed by elf_loongarch_output_arch_local_syms before
elf_link_sort_relocs, just need to call loongarch_elf_append_rela to
insert IRELATIVE relocation.
bfd/ChangeLog:
* elfnn-loongarch.c (elfNN_allocate_local_ifunc_dynrelocs): Return
type change to int.
(loongarch_elf_size_dynamic_sections): Delete (void *).
(loongarch_elf_finish_dynamic_symbol): Use loongarch_elf_append_rela
insert IRELATIVE relocation to .rela.dyn.
(elfNN_loongarch_finish_local_dynamic_symbol): Return type change to
int.
(loongarch_elf_finish_dynamic_sections): Delete process of local
ifunc symbols.
(elf_backend_output_arch_local_syms): New.
ld/ChangeLog:
* testsuite/ld-loongarch-elf/local-ifunc-reloc.d: Regenerated.

Hi,
For consistency, this patch also needs to be merged into the 2.41 branch.

+Nick.
But generally "consistency" is not a valid reason to backport a patch
into the release upcoming very soon. Is there any other reason?

I 100% agree with Xi here. Unless there is a compelling, bug-related
reason why the 2.41 branch should updated so close to a release date,
I will not approve any patch.

These two patches
https://sourceware.org/pipermail/binutils/2023-July/128421.html
are bug fixes for relaxation and the bug seems severe. Is it ok to
backport them?
If not I guess the only choice will be removing -mrelax from the default
and claiming relaxation is experimental for 2.41...
