Add map file output and option to suppress local symbols in listings Add --map option to generate a symbol map in a regular format that can be used as an import for other tools. Also add --symbols-nolocals to suppress output of local symbols in the symbol listing. In other words, only global symbols are listed. Thanks to Erik G <erik@6809.org> for the patch.
