bin * readelf.c (options): Add "decompress". (usage): Mention -z/--decompress. (parse_args): Handle -z. (uncompress_section_contents): Move to earlier in the file. (dump_section_as_strings): If requested, decompress the section before dumping. (dump_section_as_bytes): Likewise. * doc/binutils.texi: Document the new option. tests * binutils-all/z.s: New test. Checks the --decompress option to readelf. * binutils-all/readelf.exp: Run the test. * binutils-all/readelf.z: Expected output from readelf.
