* elf-bfd.h (elf_symbol_type): Add version field. * elfcode.h (elf_slurp_symbol_table): Set version field. * elflink.h (elf_link_add_object_symbols): When creating an indirect symbol for a default version symbol, set DEF_DYNAMIC if appropriate. Set up an indirection from the nondefault version of the symbol as well. (NAME(bfd_elf,size_dynamic_sections)): Call elf_link_assign_sym_version before checking whether there are any versions. Always record the version name as a dynamic symbol. Initialize counters. (elf_link_assign_sym_version): After finding a version, see if a symbol should be forced to local scope. Create a new version definition if appropriate. (elf_link_output_extsym): Correct indirect symbol handling. * elf.c (bfd_elf_print_symbol): Print version information. (bfd_section_from_shdr): Turn version sections into BFD sections. (elf_fake_sections): Only copy cverdefs and cverrefs into sh_info if sh_info is not already set. (_bfd_elf_copy_private_section_data): Copy sh_info for version sections. * elflink.c (_bfd_elf_link_record_dynamic_symbol): Tell _bfd_stringtab_add to copy the name into permanent memory if appropriate.
