1724 * dbxout.c (dbxout_parms): Correctly describe parameters passed by
1725 invisible reference in registers, but then spilled to the stack.
1726 Remove code to emit a second stab for such parameters; it attempts
1727 to describe the value's location by introducing a synthetic C++
1728 `reference' type, and then saying the stack slot has that
1729 reference type. This loses type information (breaking GDB's
1730 `ptype' command, among other things) just to describe a location
