include/
* bfdlink.h (struct bfd_link_info): Add emit_hash and emit_gnu_hash bitfields. include/elf/ * common.h (SHT_GNU_HASH, DT_GNU_HASH): Define. ld/ * scripttempl/elf.sc: Add .gnu.hash section. * emultempl/elf32.em (OPTION_HASH_STYLE): Define. (gld${EMULATION_NAME}_add_options): Register --hash-style option. (gld${EMULATION_NAME}_handle_option): Handle it. (gld${EMULATION_NAME}_list_options): Document it. * ldmain.c (main): Initialize emit_hash and emit_gnu_hash. * ld.texinfo: Document --hash-style option. bfd/ * elf.c (_bfd_elf_print_private_bfd_data): Handle DT_GNU_HASH. (bfd_section_from_shdr, elf_fake_sections, assign_section_numbers): Handle SHT_GNU_HASH. (special_sections_g): Include .gnu.hash section. (bfd_elf_gnu_hash): New function. * elf-bfd.h (bfd_elf_gnu_hash, _bfd_elf_hash_symbol): New prototypes. (struct elf_backend_data): Add elf_hash_symbol method. * elflink.c (_bfd_elf_link_create_dynamic_sections): Create .hash only if info->emit_hash, create .gnu.hash section if info->emit_gnu_hash. (struct collect_gnu_hash_codes): New type. (elf_collect_gnu_hash_codes, elf_renumber_gnu_hash_syms, _bfd_elf_hash_symbol): New functions. (compute_bucket_count): Don't compute HASHCODES array, instead add that and NSYMS as arguments. Use bed->s->sizeof_hash_entry instead of bed->s->arch_size / 8. Fix .hash size estimation. When not optimizing, use the number of hashed symbols rather than dynsymcount. (bfd_elf_size_dynamic_sections): Only add DT_HASH if info->emit_hash, and ADD DT_GNU_HASH if info->emit_gnu_hash. (bfd_elf_size_dynsym_hash_dynstr): Size .hash only if info->emit_hash, adjust compute_bucket_count caller. Create and populate .gnu.hash section if info->emit_gnu_hash. (elf_link_output_extsym): Only populate .hash section if finfo->hash_sec != NULL. (bfd_elf_final_link): Adjust assertion. Handle DT_GNU_HASH. * elfxx-target.h (elf_backend_hash_symbol): Define if not yet defined. (elfNN_bed): Add elf_backend_hash_symbol. * elf64-x86-64.c (elf64_x86_64_hash_symbol): New function. (elf_backend_hash_symbol): Define. * elf32-i386.c (elf_i386_hash_symbol): New function. (elf_backend_hash_symbol): Define. binutils/ * readelf.c (get_dynamic_type): Handle DT_GNU_HASH. (get_section_type_name): Handle SHT_GNU_HASH. (dynamic_info_DT_GNU_HASH): New variable. (process_dynamic_section): Handle DT_GNU_HASH. (process_symbol_table): Print also DT_GNU_HASH histogram. ld/testsuite/ * ld-powerpc/tlsso32.r: Adjust. * ld-powerpc/tlsso32.d: Adjust. * ld-powerpc/tlsso32.g: Adjust. * ld-powerpc/tlsso.r: Adjust. * ld-powerpc/tlsso.g: Adjust. * ld-powerpc/tlstocso.g: Adjust.
