3466 Make operand 0 input only, clobber it. Use UNSPEC, not a bogus

3468 the table index in each of the asm output templates, instead ...

3507 * dbxout.c (dbxout_parms): Correctly describe parameters passed by
3508 invisible reference in registers, but then spilled to the stack.
3509 Remove code to emit a second stab for such parameters; it attempts
3510 to describe the value's location by introducing a synthetic C++
3511 `reference' type, and then saying the stack slot has that
3512 reference type. This loses type information (breaking GDB's
3513 `ptype' command, among other things) just to describe a location
3514 which stabs can represent correctly in other ways.
