Alias analysis for exceptions in Java

摘要

We propose a flow-sensitive alias analysis algorithm that computes safe and efficient alias sets in Java. For that, we propose a references-set representation of aliased elements, its type table, and its propagation rules. Also, for an exception construct, we consider try/catch/finally blocks as well as potential exception statement nodes while building a control flow graph. Finally, for the safe alias computation on a control flow graph, we present a structural order traverse of each block and node.
