(insn:TI 110 50 107 (parallel [
            (set (reg/v:SI 3 bx [orig:82 j ] [82])
                (and:SI (mem/c:SI (plus:DI (reg/f:DI 7 sp)
                            (const_int 4 [0x4])) [3 %sfp+-524 S4 A32])
                    (const_int 255 [0xff])))
            (clobber (reg:CC 17 flags))
        ]) -1
     (nil))
