// UNSUPPORTED: ios
// When `external_symbolizer_path` is empty on Darwin we fallback on using
// dladdr as the symbolizer which means we get the symbol name
// but no source location. The current implementation also doesn't try to
// change the module name so we end up with the full name so we actually don't
// need the module map here.
