Vertices are methods a directed edge joins calling vertex to the called vertex adjacency matrix is also used does not scale well, although some insights are useful nodes of high degree are critical. In this paper, we derive decision graphs that reduce control flow graphs but preserve the branching structure of programs. Each node represents a procedure and each edge f, g indicates that procedure f calls procedure g. Even though many call graph algorithms with different precision and scalability properties have been proposed, a comprehensive understanding of sources of unsoundness, their relevance, and the capabilities of existing call graph algorithms in this respect is missing.
