3599 * dbxout.c (dbxout_parms): Correctly describe parameters passed by
3600 invisible reference in registers, but then spilled to the stack.
3601 Remove code to emit a second stab for such parameters; it attempts
3602 to describe the value's location by introducing a synthetic C++
3603 `reference' type, and then saying the stack slot has that
3604 reference type. This loses type information (breaking GDB's
3605 `ptype' command, among other things) just to describe a location
