Hi! The GNU DW_AT_GNU_macros and .debug_macro* extensions were added to DWARF5, so we should emit those even in -gstrict-dwarf -gdwarf-5 mode. Bootstrapped/regtested on x86_64-linux and i686-linux on top of the dwarf2.{def,h} patch, ok for trunk? 2016-10-14 Jakub Jelinek <jakub@redhat.com> * dwarf2out.c (dwarf2out_define, dwarf2out_undef, output_macinfo_op, optimize_macinfo_range, save_macinfo_strings): Replace DW_MACRO_GNU_* constants with corresponding DW_MACRO_* constants. (output_macinfo): Likewise. Emit .debug_macro* rather than .debug_macinfo* even for -gstrict-dwarf -gdwarf-5. (init_sections_and_labels): Use .debug_macro* labels rather than .debug_macinfo* labels even for -gstrict-dwarf -gdwarf-5. (dwarf2out_finish): Use DW_AT_macros instead of DW_AT_macro_info or DW_AT_GNU_macros for -gdwarf-5. Jakub
