  1. Call graph

    A call graph is a directed graph that represents calling relationships between subroutines in a computer program. Specifically, each node represents a procedure and each edge indicates that procedure f calls procedure g. Thus, a cycle in the graph indicates recursive procedure calls. Call graphs are a basic program analysis result that can be used for human understanding of programs, or as a basis for further analyses, such as an analysis that tracks the flow of values between procedures. One simple application of call graphs is finding procedures that are never called. Call graphs can be dynamic or static. A dynamic call graph is a record of an execution of the program, e.g., as output by a profiler. Thus, a dynamic call graph can be exact, but only describes one run of the program. A static call graph is a call graph intended to represent every possible run of the program. The exact static call graph is undecidable, so static call graph algorithms are generally overapproximations. That is, every call relationship that occurs is represented in the graph, and possibly also some call relationships that would never occur in actual runs of the program.
