header, pass the new one to _bfd_elf_make_section_from_shdr. (elf_fake_sections): Don't set sh_info and sh_entsize fields. (elf_map_symbols): Add section VMA to symbol value when comparing against 0. (_bfd_elf_compute_section_file_positions): Only build symbol table if there are some symbols. Set file offset of symtab and strtab sections. (assign_file_positions_except_relocs): Remove dosyms parameter. Change all callers. Never set file offset of symtab and strtab sections. (_bfd_elf_copy_private_section_data): New function. (MAP_ONESYMTAB, MAP_DYNSYMTAB, MAP_STRTAB, MAP_SHSTRTAB): Define. (_bfd_elf_copy_private_symbol_data): New function. (swap_out_syms): Check for special mapping of st_shndx created by copy_private_symbol_data. * elfxx-target.h: Use new copy routines. * elf-bfd.h (_bfd_elf_copy_private_symbol_data): Declare.
