2179 * dbxout.c (dbxout_parms): Correctly describe parameters passed by
2180 invisible reference in registers, but then spilled to the stack.
2181 Remove code to emit a second stab for such parameters; it attempts
2182 to describe the value's location by introducing a synthetic C++
2183 `reference' type, and then saying the stack slot has that
2184 reference type. This loses type information (breaking GDB's
2185 `ptype' command, among other things) just to describe a location
