This happens during combine, where simplify_set on
(set (reg:CC_NOOV 24 cc)
    (compare:CC_NOOV (ior:SI (unlt:SI (reg:CCFPE 24 cc)
                (const_int 0 [0]))
            (ne:SI (reg:SI 0 r0 [ x ])
                (const_int 0 [0])))
        (const_int 0 [0])))
calls SELECT_CC_MODE on the arguments of the compare (ior and const0_rtx).
