(fetch_indexed_string): New function. (fetch_indexed_value): New function. (get_FORM_name): Add DW_FORM_GNU_str_index and DW_FORM_GNU_addr_index. (decode_location_expression): Add DW_OP_GNU_addr_index. (read_and_display_attr_value): Add DW_FORM_GNU_str_index, DW_FORM_GNU_addr_index, DW_AT_GNU_addr_base, and DW_AT_GNU_ranges_base. (get_AT_name): Add new attributes for Fission. (process_debug_info): Load new debug sections for Fission. (load_debug_info): Check for .debug_info.dwo section. (display_loc_list, display_loc_list_dwo): New functions. (display_debug_loc): Move logic to above two functions. (display_debug_info): Choose abbrev section based on info section. (display_debug_types): Likewise. (display_trace_info): Likewise. (comp_addr_base): New function. (display_debug_addr): New function. (display_debug_str_offsets): New function. (display_debug_ranges): Allow missing range lists. Suppress diagnostics if dwarf_check not set. (debug_displays): Add column to select abbrev section. * dwarf.h (enum dwarf_section_display_enum): Add new debug sections for Fission. (struct dwarf_section): Add abbrev_sec field. (struct dwarf_section_display): New type. (debug_info): Add addr_base, ranges_base fields. (dwarf_check): New global variable. * objdump.c (usage): Add --dwarf-check option. (enum option_values): Add OPTION_DWARF_CHECK. (long_options): Add --dwarf-check. (main): Likewise. * readelf.c (OPTION_DWARF_CHECK): New macro. (options): Add --dwarf-check. (parse_args): Likewise. (process_section_headers): Use const_strneq instead of streq. --- binutils/dwarf.h | 68 ++++++++++++++++++++++++++++++++++++-------------------- 1 file changed, 44 insertions(+), 24 deletions(-) (limited to 'binutils/dwarf.h') diff --git a/binutils/dwarf.h b/binutils/dwarf.h index 75d93c8651..84f5080813 100644 --- a/binutils/dwarf.h +++ b/binutils/dwarf.h @@ -109,30 +109,6 @@ typedef struct } DWARF2_Internal_ARange; -struct dwarf_section -{ - /* A debug section has a different name when it's stored compressed - or not.
