dwarf2out.c (dwarf_cfi_name): Add other DWARF 3 codes.
* dwarf2out.c (dwarf_cfi_name): Add other DWARF 3 codes.
(output_cfi): Likewise. Disable DW_CFA_GNU_negative_offset_extended.
(reg_save): Use DW_CFA_offset_extended_sf instead.
* dwarf2out.c (dwarf2out_finish): Don't abort if there were errors.
