1683 * dbxout.c (dbxout_parms): Correctly describe parameters passed by
1684 invisible reference in registers, but then spilled to the stack.
1685 Remove code to emit a second stab for such parameters; it attempts
1686 to describe the value's location by introducing a synthetic C++
1687 `reference' type, and then saying the stack slot has that
1688 reference type. This loses type information (breaking GDB's
1689 `ptype' command, among other things) just to describe a location
