876 * elf-bfd.h (eh_cie_fde): Add u.cie.u.full_cie and u.cie.merged
877 fields. Rename u.cie.u.merged to u.cie.u.merged_with.
878 (eh_frame_sec_info): Add a cies field.
879 (eh_frame_hdr_info): Add a merge_cies field.
880 * elf-eh-frame.c (cie): Add a reloc_index member to the personality
881 union.
882 (_bfd_elf_begin_eh_frame_parsing): Set hdr_info->merge_cies instead
883 of hdr_info->cies.
884 (_bfd_elf_parse_eh_frame): Remove tmp_cie. Ccreate an array of
885 cie structures in all cases and use it instead of extended_cies.
886 If merging, store the cie array in sec_info->cies and point each
887 CIE's eh_fde_cie at the associated element. Do not try to
888 calculate the value of the personality routine here; record the
889 offset of the relocation instead. Do not merge CIEs here.
890 (_bfd_elf_end_eh_frame_parsing): Do not free hdr_info->cies here...
891 (_bfd_elf_discard_section_eh_frame_hdr): ...do it here instead.
892 (_bfd_elf_gc_mark_fdes): Mark the original (unmerged) CIE.
893 (find_merged_cie): New function.
