;; 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
