* elf-bfd.h (enum elf_link_info_type): New.
(struct bfd_elf_section_data): Remove stab_info and merge_info fields, add sec_info and sec_info_type. (struct elf_obj_tdata): Add eh_frame_hdr field. (_bfd_elf_discard_section_eh_frame): New prototype. (_bfd_elf_discard_section_eh_frame_hdr): Likewise. (_bfd_elf_eh_frame_section_offset): Likewise. (_bfd_elf_write_section_eh_frame): Likewise. (_bfd_elf_write_section_eh_frame_hdr): Likewise. * Makefile.am (BFD32_BACKENDS): Add elf-eh-frame.lo. (BFD32_BACKENDS_CFILES): Add elf-eh-frame.c. (elf-eh-frame.lo): New. * Makefile.in: Rebuilt. * configure.in (elf): Add elf-eh-frame.lo. * configure: Rebuilt. * elf.c (_bfd_elf_print_private_bfd_data): Support PT_GNU_EH_FRAME. (map_sections_to_segments): Create PT_GNU_EH_FRAME if requested. (get_program_header_size): Take into account PT_GNU_EH_FRAME segment. (_bfd_elf_rela_local_sym): Use sec_info_type and sec_info. (_bfd_elf_rel_local_sym): Likewise. (_bfd_elf_section_offset): Likewise. Call _bfd_elf_eh_frame_section_offset too. * elfxx-ia64.c (elfNN_ia64_relocate_section): Use sec_info_type and sec_info. * elf64-alpha.c (elf64_alpha_relocate_section): Likewise. * elf-eh-frame.c: New file. * elflink.h (elf_link_add_object_symbols): Don't optimize SHF_MERGE .stab sections. Set sec_info_type, use sec_info instead of merge_info and stab_info. (elf_link_create_dynamic_sections): Create .eh_frame_hdr section if --eh-frame-hdr. (elf_bfd_final_link): Write .eh_frame_hdr section. (elf_link_sec_merge_syms): Use sec_info_type and sec_info. (elf_link_input_bfd): Likewise. Call _bfd_elf_write_section_eh_frame to write .eh_frame sections. (elf_bfd_discard_info): Add output_bfd argument. Call _bfd_elf_discard_section_eh_frame and _bfd_elf_discard_section_eh_frame_hdr. (elf_section_ignore_discarded_relocs): Use sec_info_type, not section names. * bfd-in.h (bfd_elf32_discard_info, bfd_elf64_discard_info): Adjust prototypes. * bfd-in2.h (bfd_elf32_discard_info, bfd_elf64_discard_info): Likewise. * elf/common.h (PT_GNU_EH_FRAME): Define. * bfdlink.h (struct bfd_link_info): Add eh_frame_hdr field. * emultempl/elf32.em (finish): Supply output_bfd to bfd_elf*_discard_info. (OPTION_EH_FRAME_HDR): Define. (longopts): Add --eh-frame-hdr. (parse_args): Handle it. (list_options): Add --eh-frame-hdr to help. * emultempl/hppaelf.em (finish): Supply output_bfd to bfd_elf*_discard_info. * scripttempl/elf.sc (.eh_frame_hdr): Add. * readelf.c (get_segment_type): Support PT_GNU_EH_FRAME.
