* ld-mips-elf/eh-frame1-n32.d: Expect a warning about .eh_frame_hdr.
	Remove duplicate CIEs.  Adjust relocation addresses and .eh_frame
	offsets accordingly.  Do not allow there to be any trailing
	R_MIPS_NONE relocations.
	* ld-mips-elf/eh-frame1-n64.d: Likewise.
	* ld-mips-elf/eh-frame2-n32.d: Likewise.
	* ld-mips-elf/eh-frame2-n64.d: Likewise.

Richard Sandiford 353057a53c * elf-bfd.h (eh_cie_fde): Add new fields: add_augmentation_size and 
add_fde_encoding.  Remove need_relative.
	* elf-eh-frame.c (extra_augmentation_string_bytes)
	(extra_augmentation_data_bytes, size_of_output_cie_fde): New functions.
	(_bfd_elf_discard_section_eh_frame): Consider changing the FDE encoding
	in cases where the CIE has no existing 'R' augmentation.  Use
	size_of_output_cie_fde when assigning offsets.  Use the final offset
	as the new section size.
	(_bfd_elf_eh_frame_section_offset): Remove need_relative handling.
	Account for any extra augmentation bytes in the returned offset.
	(_bfd_elf_write_section_eh_frame): Rework so that the entries are
	moved before being modified.  Pad growing entries with DW_CFA_nops.
	Add 'z' and 'R' augmentations as directed by add_augmentation_size
	and add_fde_encoding.
