823 * dbxout.c (dbxout_parms): Correctly describe parameters passed by
824 invisible reference in registers, but then spilled to the stack.
825 Remove code to emit a second stab for such parameters; it attempts

828 reference type. This loses type information (breaking GDB's
829 `ptype' command, among other things) just to describe a location
