* elflink.h (elf_link_add_archive_symbols): If a default symbol is not found, try looking it up again without the version name. (elf_link_add_object_symbols): Always link against the dynamic symbol table of a dynamic object. When linking against a dynamic object, include version strings in symbol names, and set up version information. Add indirect symbols for default versions. (elf_link_create_dynamic_sections): Add special version sections. (struct elf_assign_sym_version_info): Define. (struct elf_find_verdep_info): Define. (NAME(bfd_elf,size_dynamic_sections)): Add verdefs parameter. Set up version sections. (elf_adjust_dynamic_symbol): Ignore indirect symbols. (elf_link_find_version_dependencies): New static function. (elf_link_assign_sym_version): New static function. (elf_link_renumber_dynsyms): New static function. (struct elf_final_link_info): Add symver_sec field. (elf_bfd_final_link): Initialize finfo.symver_sec. Don't count local symbols of a dynamic object. Handle DT_VER* constants. (elf_link_output_extsym): Simplify BFD_ASSERT checking for a dynamic object. Skip indirect symbols from ELF objects. Remove the version name before choosing a hash bucket. Write out the version information if appropriate. (elf_link_input_bfd): Check for DYNAMIC, not ET_DYN. * bfd-in.h (bfd_elf32_size_dynamic_sections): Update declaration. (bfd_elf64_size_dynamic_sections): Likewise. * bfd-in2.h: Rebuild. * elf-bfd.h (struct elf_link_hash_entry): Add verinfo field. Change elf_link_hash_flags to unsigned short. (ELF_LINK_HIDDEN): Define. (struct elf_obj_tdata): Add fields dynversym_hdr, dynverref_hdr, dynverdef_hdr, dynversym_section, dynverdef_section, dynverref_section, cverdefs, cverrefs, verdef, verref. (elf_dynversym, elf_dynverdef, elf_dynverref): Define. (_bfd_elf_swap_verdef_in, _bfd_elf_swap_verdef_out): Declare. (_bfd_elf_swap_verdaux_in, _bfd_elf_swap_verdaux_out): Declare.

(_bfd_elf_print_private_bfd_data): Add DT_VER* constants. Print version information if there is any. (_bfd_elf_link_hash_newfunc): Initialize verinfo field. (bfd_section_from_shdr): Handle SHT_GNU_ver* section types. (elf_fake_sections): Handle .gnu.version* section names. (assign_section_numbers): Handle SHT_GNU_ver* section types. (_bfd_elf_slurp_version_tables): New function. * elflink.c (_bfd_elf_link_record_dynamic_symbol): Don't include version name in string entered in dynamic hash table. * elfcode.h: Include fnmatch.h. * elf32-i386.c (elf_i386_relocate_section): Handle a dynamic symbol which was forced to become local. * elf32-m68k.c (elf_m68k_relocate_section): Likewise. * elf32-ppc.c (ppc_elf_relocate_section): Likewise. * elf32-sparc.c (elf32_sparc_relocate_section): Likewise. * elf64-alpha.c (alpha_elf_dynamic_symbol_p): Likewise.
