The control dependence relation plays a fundamental role in program restructuring and optimization. The usual representation of this relation is the control dependence graph (CDG), but the size of the CDG can grow quadratically with the input programs, even for structured programs. In this article, we introduce the augmented postdominator tree <italic>(APT)</italic>, a data structure which can be constructed in space and time proportional to the size of the program and which supports… CONTINUE READING
