Probably wouldn't have much effect, as the philosophy of RISC is to
hold scalars in the register bank.  However, it does point up an
interesting problem -- does the Berkeley RISC require a parallel stack,
maintained by software protocols, to hold structures, arrays, and other
humongous local variables?
