1172 * dbxout.c (dbxout_parms): Correctly describe parameters passed by
1173 invisible reference in registers, but then spilled to the stack.
1174 Remove code to emit a second stab for such parameters; it attempts
1175 to describe the value's location by introducing a synthetic C++
1176 `reference' type, and then saying the stack slot has that
1177 reference type. This loses type information (breaking GDB's
1178 `ptype' command, among other things) just to describe a location
