3061 the table index in each of the asm output templates, instead ...

3100 * dbxout.c (dbxout_parms): Correctly describe parameters passed by
3101 invisible reference in registers, but then spilled to the stack.
3102 Remove code to emit a second stab for such parameters; it attempts
3103 to describe the value's location by introducing a synthetic C++
3104 `reference' type, and then saying the stack slot has that
3105 reference type. This loses type information (breaking GDB's
3106 `ptype' command, among other things) just to describe a location
