* NEWS: Mention feature match between objdump and readelf for dumping dwarf info. * doc/binutils.texi (objdump): Document -W/--dwarf improvments to objdump. * objdump.c (usage): Update documentation for -W/--dwarf. (enum option_values): Add OPTION_DWARF. (long_options): --dwarf can accept arguments. (dump_dwarf_section): Also check enabled field. (main): Option -W can accept arguments, code moved to dwarf.c and call dwarf_select_sections_all instead. * readelf.c (process_section_headers): Remove do_debug_lines_decoded. (parse_args): Move code to... * dwarf.c (dwarf_select_sections_by_letters, dwarf_select_sections_by_names): : ...here (new functions). (do_debug_lines_decoded): Remove and replaced by ... (FLAG_DEBUG_LINES_RAW, FLAG_DEBUG_LINES_DECODED): ... new macros. (display_debug_lines): Adjust for previous change. (dwarf_select_sections_all): New function. (debug_displays): Add initializer for enabled field. * dwarf.h (do_debug_lines_decoded): Remove. Add prototypes for the new functions. (struct dwarf_section_display): Add enabled field.
