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