Program analysis automatically reasons about program runtime behavior and provides mechanisms to determine whether a program’s execution will satisfy certain properties. Program analysis offers a rich spectrum of methods for improving software reliability. A variety of program analysis problems can be formulated as graph reachability problems in edge-labeled graphs. Over the years, we have witnessed the tremendous success of various graph-reachability-based program-analysis techniques. In this talk, I will discuss our work in the past three years on CFL-reachability, Dyck-reachability, and InterDyck-reachability.
