llvm-nm Mach-O Specific Options:
--add-dyldinfo Add symbols from the dyldinfo not already in the symbol table
--add-inlinedinfo Add symbols from the inlined libraries, TBD only
--arch=<value> architecture(s) from a Mach-O file to dump

llvm-nm XCOFF Specific Options:
--no-rsrc Exclude resource file symbols (__rsrc) from the export symbol list.
Pass @FILE as argument to read options from FILE.
