1753 * elf-bfd.h (eh_cie_fde): Add u.cie.u.full_cie and u.cie.merged
1754 fields. Rename u.cie.u.merged to u.cie.u.merged_with.
1755 (eh_frame_sec_info): Add a cies field.
1756 (eh_frame_hdr_info): Add a merge_cies field.
1757 * elf-eh-frame.c (cie): Add a reloc_index member to the personality
1758 union.
1759 (_bfd_elf_begin_eh_frame_parsing): Set hdr_info->merge_cies instead
1760 of hdr_info->cies.
1761 (_bfd_elf_parse_eh_frame): Remove tmp_cie. Ccreate an array of
1762 cie structures in all cases and use it instead of extended_cies.
1763 If merging, store the cie array in sec_info->cies and point each
1764 CIE's eh_fde_cie at the associated element. Do not try to
1765 calculate the value of the personality routine here; record the
1766 offset of the relocation instead. Do not merge CIEs here.
1767 (_bfd_elf_end_eh_frame_parsing): Do not free hdr_info->cies here...
1768 (_bfd_elf_discard_section_eh_frame_hdr): ...do it here instead.
1769 (_bfd_elf_gc_mark_fdes): Mark the original (unmerged) CIE.
1770 (find_merged_cie): New function.
1771 (_bfd_elf_gc_mark_fdes): Use it. Free sec_info->cies.
