* register aside of the output Preg, nor uses the stack, since it
* could be called with an invalid stack pointer, or the current stack
* space being uncovered by any CPLB (e.g. early exception handling).
*
* The constraints on the second form are a bit relaxed, and the code
* is allowed to use the specified Dreg for determining the PDA
