;; ??? It is OK for fill_simple_delay_slots to put load/store instructions
;; in a delay slot, but it is not OK for fill_eager_delay_slots to do so.
;; This is because doing so will add several pipeline stalls to the path

;; the same code as v8 (the addx/subx method has more applications).  The
;; exception to this is "reg != 0" which can be done in one instruction on v9
;; (so we do it).  For the rest, on v9 we use conditional moves; on v8, we do
;; branches.

;; Seq_special[_xxx] and sne_special[_xxx] clobber the CC reg, because they
