Treffer: Visualization of Program Dependence Graphs.

The analysis of a compiler΄s intermediate data structures helps at debugging complex optimizations. We present a graphical tool for analyzing the program dependence graph of Sun Microsystems΄ Java HotSpot^TM server compiler. The tool saves snapshots of the graph during the compilation. It displays the graphs and provides filtering mechanisms based on customizable JavaScript code and regular expressions. High performance and sophisticated navigation possibilities enable the tool to handle large graphs with thousands of nodes. [ABSTRACT FROM AUTHOR]
