(Note: This patch has already been accepted/committed in binutils/GDB. This will bring the same change into the GCC tree.) For DWARF v5 Dwarf Package Files (.dwp files), the section identifier encodings have changed. This patch updates dwarf2.h to contain the new encodings. The table below shows the old & new encodings: [ref http://dwarfstd.org/doc/DWARF5.pdf, section 7.3.5. ] Val DW4 section DW4 section id DW5 section DW5 section id --- ----------------- -------------- ----------------- -------------- 1 .debug_info.dwo DW_SECT_INFO .debug_info.dwo DW_SECT_INFO 2 .debug_types.dwo DW_SECT_TYPES -- reserved 3 .debug_abbrev.dwo DW_SECT_ABBREV .debug_abbrev.dwo DW_SECT_ABBREV 4 .debug_line.dwo DW_SECT_LINE .debug_line.dwo DW_SECT_LINE 5 .debug_loc.dwo DW_SECT_LOC .debug_loclists.dwo DW_SECT_LOCLISTS 6 .debug_str_offsets.dwo .debug_str_offsets.dwo DW_SECT_STR_OFFSETS DW_SECT_STR_OFFSETS 7 .debug_macinfo.dwo DW_SECT_MACINFO .debug_macro.dwo DW_SECT_MACRO 8 .debug_macro.dwo DW_SECT_MACRO .debug_rnglists.dwo DW_SECT_RNGLISTS 2020-09-09 Caroline Tice <cmtice@google.com> include/ * dwarf2.h (enum dwarf_sect_v5): A new enum section for the sections in a DWARF 5 DWP file (DWP version 5).
