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.
