+ Copy make_relative and add_augmentation_size from the CIE
+ to the FDE.
+ (_bfd_elf_discard_section_eh_frame): Use the FDE's own
+ make_relative field.
+ (_bfd_elf_eh_frame_section_offset): Likewise.

+
+ * elf-bfd.h (eh_cie_fde): Remove need_lsda_relative.
+ Move make_lsda_relative to u.cie.
+ * elf-eh-frame.c (cie): Rename make_lsda_relative to
+ can_make_lsda_relative.
+ (_bfd_elf_parse_eh_frame): Don't set the old eh_cie_fde
+ make_lsda_relative field. Update after cie renaming.
+ Set u.cie.make_lsda_relative if can_make_lsda_relative
+ and if we find a relocation against the LSDA.
+ (_bfd_elf_discard_section_eh_frame): Copy make_lsda_relative when
+ changing a CIE's group representative.
+ (_bfd_elf_eh_frame_section_offset): Don't set need_ldsa_relative here.

+ * 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
