Changeset 11058:38121b8b2462 --------------------------- x86: implement rcpps and rcpss SSE insts These are packed single-precision approximate reciprocal operations, vector and scalar versions, respectively. This code was basically developed by copying the code for sqrtps and sqrtss. The mrcp micro-op was simplified relative to msqrt since there are no double-precision versions of this operation.
