Title:Context-Sensitive Pointer Analysis Based On Procedural Summaries
Author(s):Kim, Hong-Seok
Subject(s):computer science
Abstract:This dissertation addresses the scalability problem of context-sensitive pointer analysis based on Andersen's inclusion-based approach. The key observation is that procedures without any observable effects on callers, roughly termed procedural side effects, are never involved in the generation of spurious interprocedural dataflow. Therefore, by carefully migrating procedural side effects from callees to callers, we can transform a program into a side-effect free form yet with the same overall pointer information. In such a case, the scalability of the overall algorithm is determined by the size of procedural summaries propagated during the bottom-up phase. To reduce the size of procedural summaries, we have developed a number of simplification algorithms that produce an observably equivalent yet smaller procedural summaries. Overall, the accuracy of the proposed context-sensitive analysis is equivalent to that achieved by exhaustively inlining all procedure calls with the exception for recursive calls. On the other hand, thanks to the simplification algorithms, the scalability of the proposed context-sensitive analysis is comparable to that achieved by context-insensitive analysis.
