IPC: G06F9/44
Filed: 1985-06-27
Abstract: PURPOSE:To execute efficiently PD division to which the presence of loop is minded, by using a few resources, by tracking back to a start spot of its loop and dividing again a produre block by using a dictionary relateddto the loop, when a procedure block dividing spot is on the way of the loop. CONSTITUTION:In a spot 1, a fact that a loop '0' is started is displayed on an SCR dictionary. A loop (loop 1) containing directly a spot 2 is different from that of the spot 1, and it is known from the SCR dictionary that a loop start point of the loop 1 hs not appeared yet. As a result, a fact that the loop 1 is started is displayed on the loop 1 element of the SCR dictionary. For instance, in a spot 3, a PD (procedure block) division is about to occur. It is known from the loop 1 element of the SCR dictionary that the spot 3 belongs to a PD1, and the start point of the loop 1 containing directly the spot 3 also belongs to the PD1. Therefore, a redivision is executed at a redividing spot (loop start point) 2 shown by the loop 1 element of the SCR dictionary. In this way, a dividing point of the PD1 and the PD2 is determined, and such a divided state as show in the figure is obtained.
