Re: MIPS elimate trap-if-zero instruction if possible for divisions

Hi Jeff, Richard We could possibly also use VRP to change signed division to unsigned division when dividing a non-negative signed operand by a power of 2 because then the sign bit will be 0 and we could do the division using logical shift right.   Graham
