PowerPC64 ld --no-power10-stubs
Needed for libraries that use ifuncs or other means to support cpu-optimized versions of functions, some power10, some not, and those functions make calls using linkage stubs. bfd/ * elf64-ppc.h (struct ppc64_elf_params): Add power10_stubs. * elf64-ppc.c (struct ppc_link_hash_table): Delete power10_stubs. (ppc64_elf_check_relocs): Adjust setting of power10_stubs. (plt_stub_size, ppc_build_one_stub, ppc_size_one_stub): Adjust uses of power10_stubs. ld/ * emultempl/ppc64elf.em (params): Init new field. (enum ppc64_opt): Add OPTION_POWER10_STUBS and OPTION_NO_POWER10_STUBS. (PARSE_AND_LIST_LONGOPTS): Support --power10-stubs and --no-power10-stubs. (PARSE_AND_LIST_OPTIONS, PARSE_AND_LIST_ARGS_CASES): Likewise. * testsuite/ld-powerpc/callstub-3.d: New test. * testsuite/ld-powerpc/powerpc.exp: Run it.
