	bfd            : ChangeLog elf-bfd.h elf-eh-frame.c elflink.c 

Log message:
	bfd/
	* 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.
