--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.

```
(define_insn "*rsqrtsf2_sse"
  [(set (match_operand:SF 0 "register_operand" "=x,x,x,x")
        (unspec:SF [(match_operand:SF 1 "nonimmediate_operand" "0,x,m,ja")]
                   UNSPEC_RSQRT))]
  "TARGET_SSE && TARGET_SSE_MATH"
```

I suspect this should not have `&& TARGET_SSE_MATH` "rsqrtsf2" should keep it
though.
