1729 * dbxout.c (dbxout_parms): Correctly describe parameters passed by
1730 invisible reference in registers, but then spilled to the stack.
1731 Remove code to emit a second stab for such parameters; it attempts
1732 to describe the value's location by introducing a synthetic C++
1733 `reference' type, and then saying the stack slot has that
1734 reference type. This loses type information (breaking GDB's
1735 `ptype' command, among other things) just to describe a location
