+       * elf-bfd.h (eh_cie_fde): Add u.cie.  Document how u.fde.cie_inf
+       changes when removed == 0.
+       (eh_frame_hdr_info): Add parsed_eh_frames.
+       (_bfd_elf_begin_eh_frame_parsing): Declare.
+       (_bfd_elf_parse_eh_frame): Declare.
+       (_bfd_elf_end_eh_frame_parsing): Declare.
+       * elf-eh-frame.c (_bfd_elf_begin_eh_frame_parsing): New function.
+       (_bfd_elf_parse_eh_frame): New function, split out from
+       _bfd_elf_discard_section_eh_frame.  Make a first pass through the
+       buffer to calculate the number of entries and CIEs.  Allocate memory
+       for them before the main loop.  Replace current extended cie
+       representation with a pair of pointers, one to the local eh_cie_fde
+       and one to the full struct cie.  Allocate a separate array of struct
+       cies if not merging.  Merge CIEs during the main loop and set up each
+       u.cie.merged field.  Point an FDE's cie_inf field directly at the
+       local CIE.  Initially assume that all entries should be removed.
+       (_bfd_elf_end_eh_frame_parsing): New function.
+       (_bfd_elf_discard_section_eh_frame): Assume that the section has
+       already been parsed.  Use a separate pass to mark entries that
+       need to be kept.  Use the u.cie.merged field to track a CIE's
+       group representative.
+       * elflink.c (bfd_elf_discard_info): Call _bfd_elf_parse_eh_frame
+       before _bfd_elf_discard_section_eh_frame.  Wrap loop with calls to
+       _bfd_elf_begin_eh_frame_parsing and _bfd_elf_end_eh_frame_parsing.

        * elf-bfd.h (eh_cie_fde): Put cie_inf in a union.  Add a reloc_index
