	* elf-bfd.h (eh_cie_fde): Add u.fde.next_for_section and
	u.cie.gc_mark.
	(bfd_elf_section_data): Add fde_list.
	(elf_fde_list): New macro.
	(elf_obj_tdata): Add eh_frame_section.
	(elf_eh_frame_section): New macro.
	(_bfd_elf_gc_mark_reloc): Remove last parameter.
	(_bfd_elf_gc_mark_fdes): Declare.
	* elf-eh-frame.c (_bfd_elf_get_eh_frame_sec_info): Chain the FDEs
	for each input section.
	(mark_entry, _bfd_elf_gc_mark_fdes): New functions.
	* elflink.c (_bfd_elf_gc_mark_reloc): Remove is_eh parameter.
	(_bfd_elf_gc_mark): Update call accordingly.  Mark the relocations
	againts the section's FDEs.  Don't mark the bfd's elf_eh_frame_section.
	(bfd_elf_gc_sections): Parse each input bfd's .eh_frame before
	marking any input sections.  Remove the current EH handling.
	* section.c (bfd_section): Remove gc_mark_from_eh.
	* ecoff.c (bfd_debug_section): Update initializer accordingly.
