/* Explanation of "more" field: bit 6 is whether to use shift path. If we are using the shift path, bit 7 is whether the divisor is negative in the signed case; in the unsigned case it is 0. Bits 0-4 is shift value (for shift path or mult path). In 32 bit case, bit 5 is always 0. We use bit 7 as the "negative divisor indicator" so that we can use sign extension to efficiently go to a full-width -1. /* Explanation of "more" field: bit 6 is whether to use shift path.
