The patterns match mode SF, but the insns have mode SQ.
sorry actually the patterns are like this
(insn 69 34 70 (set (reg:SF 0 d0)
(reg:SF 18 f2)) 79 {movsf} (nil)
(nil))
(insn 70 69 35 (set (reg:SF 16 f0 [orig:38 D.3693 ] [38])
(reg:SF 0 d0)) 79 {movsf} (nil)
(nil))
and the peephole is same as the above
