We present a simple yet useful technique for refining the control structure of loops that occur in imperative programs. Loops containing complex control flow are common in synchronous embedded controllers derived from modeling languages such as Lustre, Esterel, and Simulink/Stateflow. Our approach uses a set of labels to distinguish different control paths inside a given loop. The iterations of the loop are abstracted as a finite state automaton over these labels. Subsequently, we use static… CONTINUE READING
