[Bug target/21508] non-optimal code with __builtin_signbit

[pinskia at gcc dot gnu dot org]

------- Comment #3 from pinskia at gcc dot gnu dot org  2006-10-22 21:01 -------
On the mainline we get:
        subl    $12, %esp
        fld1
        faddl   16(%esp)
        fstpl   (%esp)
        movl    4(%esp), %eax
        addl    $12, %esp
        andl    $-2147483648, %eax
        ret

Which is optimial as there is no extra movl and there is fld1.
