Hi, The loop after SMS transformation would at least execute stage_count times (due to the duplication in prolog/epilog). To avoid the loop with loop_count < stage_count execute the sms version loop, SMS will try to get loop iteration count.
Currently, SMS would get iteration count by finding the instruction which setup the iteration count. The instruction would generate by doloop optimization. To remove the dependency on doloop pass, we generalize the method by using get_simple_loop_desc function to get loop iteration count. Thanks, Shiva
