Hmm, I get (but that looks like different branch predictions):
_testf:
        fldl    4(%esp)
        ftst
        fnstsw  %ax
        testb   $64, %ah
        jne     L10
        ftst
        fnstsw  %ax
        fstp    %st(0)
        testb   $69, %ah
        jne     L5
        fld1
        ret
        .align 2,0x90
L10:
        fstp    %st(0)
        fldz
        ret
L5:
        flds    LC2
        ret
