* elf64-ppc.c (create_linkage_sections): Don't create .rela.rodata.brlt for --emit-relocs. (ppc_build_one_stub): Create relocs for brlt --emit-relocs here. (ppc_size_one_stub): Count them. Simplify test of stub type when counting stub relocs. Set SEC_RELOC too. (ppc64_elf_size_stubs): Clear reloc_count and SEC_RELOC. (ppc64_elf_finish_dynamic_sections): Output brlt relocs. ld/testsuite/ * ld-powerpc/relbrlt.d: Update.
