--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
We even miss f3 into f4:
unsigned f3(unsigned a)
{
        long b5 = (a & 0x20)>>5;
        long b3 = (a & 0x08)>>3;
        return b5 ^ b3;
}
unsigned f4(unsigned a)
{
        unsigned b5 = (a ^ (a << 2));
        return (b5>>5)&1;
}
