3473 the table index in each of the asm output templates, instead ...

3512 * dbxout.c (dbxout_parms): Correctly describe parameters passed by
3513 invisible reference in registers, but then spilled to the stack.
3514 Remove code to emit a second stab for such parameters; it attempts
3515 to describe the value's location by introducing a synthetic C++
3516 `reference' type, and then saying the stack slot has that
3517 reference type. This loses type information (breaking GDB's
3518 `ptype' command, among other things) just to describe a location
