(insn 31 30 10 2 (parallel [
            (set (reg:SI 0 ax [95])
                (udiv:SI (reg/v:SI 0 ax [orig:93 a ] [93])
                    (reg/v:SI 4 si [orig:94 b ] [94])))
            (set (reg:SI 1 dx [96])
                (umod:SI (reg/v:SI 0 ax [orig:93 a ] [93])
                    (reg/v:SI 4 si [orig:94 b ] [94])))
