A unified program analysis framework that facilitates the analysis of complex multi-language software systems, analysis reuse, and analysis comparison, by employing techniques such as program translation and automatic results mapping, is presented. The feasibility and effectiveness of such a framework are demonstrated using a sample application of the framework. The comparison yields new insights into the effectiveness of the techniques employed in both analysis tools. These encouraging results yield the observation that such a unified program analysis framework will prove to be valuable both as a testbed for examining different language analysis techniques, and as a unified toolset for broad program analysis.
