peephole patterns are not matching

[Mohamed Shafi]

hello everyone,

I have the following 2 patterns which are consecutive. (from shorten
rtl dump file)

(insn 69 34 70 (set (reg:SQ 0 d0)
       (reg:SQ 18 f2)) 79 {movsq} (nil)
   (nil))

(insn 70 69 35 (set (reg:SQ 16 f0 [orig:38 D.3693 ] [38])
       (reg:SQ 0 d0)) 79 {movsq} (nil)
   (nil))


For the above pattern i wrote a peephole like this

(define_peephole
 [(set (match_operand:SF 0 "data_reg" "=d")
          (match_operand:SF 1 "float_reg"  "f"))
   (set (match_operand:SF 2 "float_reg" "=f")
          (match_operand:SF 3 "data_reg"  "d"))]
 "REGNO(operands[0]) == REGNO(operands[3])"
 "movf\\t%1, %3"
)

even i wrote define_peephole2 which is similar to the above.
But the above patterns are not matched at all. But i can find these
patterns in the rtl dumps.

What could be the reason for this behavior?
