created. No special action is taken: the result and its CR Field
are stored "as usual" exactly as all other SVP64 Rc=1 operations.
-Implementors must keep in mind that Parallel Reduction is an abstracted
-concept of a "Schedule" that issues Scalar Operations. It is
-**not permitted** to assume that the accuracy can be made higher than that
-of performing the exact same Scalar instructions just because a Parallel
-Reduction Schedule is being used.
-
-Also note that the Schedule only makes sense on top of certain instructions:
-X-Form with a Register Profile of `RT,RA,RB` is fine.
