LRA doesn't substitute frame reg with bp. In _.209r.reload, we still have:



(insn 6 3 7 2 (set (reg:CCZ 17 flags)

        (compare:CCZ (mem/j/c:SI (plus:SI (reg/f:SI 20 frame)

                    (const_int -32 [0xffffffffffffffe0])) [0 x+0 S4 A32])

            (const_int 4 [0x4]))) pr55672.c:4 7 {*cmpsi_1}

     (nil))



Adding CC.
