2149 * dbxout.c (dbxout_parms): Correctly describe parameters passed by
2150 invisible reference in registers, but then spilled to the stack.
2151 Remove code to emit a second stab for such parameters; it attempts
2152 to describe the value's location by introducing a synthetic C++
2153 `reference' type, and then saying the stack slot has that
2154 reference type. This loses type information (breaking GDB's
2155 `ptype' command, among other things) just to describe a location
