;; Floating-point insns, excluding normal data motion.

;; PowerPC has a full set of single-precision floating point instructions.
;;
;; For the POWER architecture, we pretend that we have both SFmode and
;; DFmode insns, while, in fact, all fp insns are actually done in double.
;; The only conversions we will do will be when storing to memory.  In that
;; case, we will use the "frsp" instruction before storing.
;;
;; Note that when we store into a single-precision memory location, we need to
;; use the frsp insn first.  If the register being stored isn't dead, we
;; need a scratch register for the frsp.  But this is difficult when the store
;; is done by reload.  It is not incorrect to do the frsp on the register in
;; this case, we just lose precision that we would have otherwise gotten but
;; is not guaranteed.  Perhaps this should be tightened up at some point.
