binutils* dwarf.c (do_checks): New global variable. (display_formatted_table): Warn about an unexpected number of columns in the table, if checks are enabled. Do not complain about the lack of data following the number of entries in the table if the table is empty. (display_debug_lines_decoded): Only warn about an unexpected number of columns in a table if checks are enabled. * dwarf.h (do_checks): Add a prototype. * elfcomm.c (error): Remove weak attribute. (warn): Likewise. * readelf.c (do_checks): Delete. (warn): Delete. (process_section_headers): Only warn about empty sections if checks are enabled. gas * dwarf2dbg.c (out_dir_and_file_list): Add comments describing the construction of a DWARF-5 directory name table. * testsuite/gas/elf/pr25917.d: Update expected output.
