* elf-bfd.h (struct eh_cie_fde): Add set_loc pointer. * elf-eh-frame.c (skip_cfa_op): Fix handling of DW_CFA_advance_loc. Handle DW_CFA_{remember,restore}_state, DW_CFA_GNU_window_save, DW_CFA_val_{offset{,_sf},expression}. (skip_non_nops): Record number of DW_CFA_set_loc ops. (_bfd_elf_discard_section_eh_frame): Require skip_non_nops recognizes all ops. If there are any DW_CFA_set_loc ops and they are pcrel or going to be pcrel, compute set_loc array. (_bfd_elf_eh_frame_section_offset): If make_relative, kill relocations against DW_CFA_set_loc operands. (_bfd_elf_write_section_eh_frame): Handle DW_CFA_set_loc adjusting. * ld-elf/eh4.d: New test. * ld-elf/eh4.s: New file. * ld-elf/eh4a.s: New file.
