Description Michael Saboff 2013-02-04 10:59:49 PST

ARMv7S processors have the integer division instructions sdiv and udiv (signed and unsigned divide).  When we speculate that we have integer operands and need an integer result, we should take advantage of these instructions to compute divide (/) and modulo (%) results.
