--- Comment #17 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
For the scalar version we could match:
(set (reg:SI 106)
    (xor:SI (neg:SI (ne:SI (reg:CC 66 cc)
                (const_int 0 [0])))
        (reg:SI 107 [ MEM[(int *)a_14(D) + ivtmp.14_9 * 1] ])))

In the backend to do the csinv but it might not catch all of them because
combine does not match everything.
