PowerPC64 --no-pcrel-optimize
This new option effectively ignores R_PPC64_PCREL_OPT, disabling the
optimization of instructions marked by that relocation. The patch
also disables GOT indirect to GOT/TOC pointer relative code editing
when --no-toc-optimize.
bfd/
* elf64-ppc.h (struct ppc64_elf_params): Add no_pcrel_opt.
* elf64-ppc.c (ppc64_elf_relocate_section): Disable GOT reloc
optimizations when --no-toc-optimize. Disable R_PPC64_PCREL_OPT
optimization when --no-pcrel-optimize.
ld/
* emultempl/ppc64elf.em (params): Init new field.
(enum ppc64_opt): Add OPTION_NO_PCREL_OPT.
(PARSE_AND_LIST_LONGOPTS, PARSE_AND_LIST_OPTIONS),
(PARSE_AND_LIST_ARGS_CASES): Support --no-pcrel-optimize.
