I have a question about determinism in FPU and SSE computations. Suppose thatI have a mixed sequence ofboth FPUand SSE instructions. Then I run it on different types of Intel microprocessors keeping the same starting conditions (general registers, FPU registers, memory etc). Will the final results be bit-by-bit equalon all processors? Are there any rules to predict and avoid undetermined results of FPU or SSE computations?
