1061 the table index in each of the asm output templates, instead ...

1100 * dbxout.c (dbxout_parms): Correctly describe parameters passed by
1101 invisible reference in registers, but then spilled to the stack.

1104 `reference' type, and then saying the stack slot has that
1105 reference type. This loses type information (breaking GDB's
1106 `ptype' command, among other things) just to describe a location
1107 which stabs can represent correctly in other ways.
