Using a 'V' constraint with QI mode....

The V constraint is essentially implemented by checking that the addressing mode presented is NOT offsettable. But that's done by adding GET_MODE_SIZE(mode) - 1.
I've got a machine that supports indirection but not offsetting or indexing. But the V constraint fails for any
(mem:QI (reg:SI p0 ) )
Am I missing some trick that would allow me to make effective use of V?
