3066 * elf-bfd.h (eh_cie_fde): Add u.cie.u.full_cie and u.cie.merged
3067 fields. Rename u.cie.u.merged to u.cie.u.merged_with.

3069 (eh_frame_hdr_info): Add a merge_cies field.
3070 * elf-eh-frame.c (cie): Add a reloc_index member to the personality
3072 (_bfd_elf_begin_eh_frame_parsing): Set hdr_info->merge_cies instead
3074 (_bfd_elf_parse_eh_frame): Remove tmp_cie. Ccreate an array of
3075 cie structures in all cases and use it instead of extended_cies.
3076 If merging, store the cie array in sec_info->cies and point each
3077 CIE's eh_fde_cie at the associated element. Do not try to
3078 calculate the value of the personality routine here; record the
3079 offset of the relocation instead. Do not merge CIEs here.

3083 (find_merged_cie): New function.
