1784 * dbxout.c (dbxout_parms): Correctly describe parameters passed by
1785 invisible reference in registers, but then spilled to the stack.
1786 Remove code to emit a second stab for such parameters; it attempts
1787 to describe the value's location by introducing a synthetic C++
1788 `reference' type, and then saying the stack slot has that
1789 reference type. This loses type information (breaking GDB's
1790 `ptype' command, among other things) just to describe a location
