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.
