Abstract

Control dependence analysis is a key step in many program analysis techniques such as program slicing. The current approaches that compute control dependencies have two limitations. First, they are monolithically computed for the whole program at once. Second, these approaches do not compute the relevant program flows with the control dependency. They consider the relevant flows a slicing issue. This work extends our previous work that computes on demand the control dependencies for a particular program statement without making a comprehensive analysis. It defines new concepts in static program analysis discipline, that will be a new foundation for many future works in static program analysis. Moreover, it significantly optimizes our previous work. Finally, it presents a new approach that can compute the relevant predicates and goto statements to a particular control dependency. The contribution of this work is well-proved, and it has succeeded with hundreds of examples. However, this is the first work that claims that it can compute accurately and on demand the control dependencies with its relevant flows.
