I want to announce that the first version of the "Java HotSpot Client
Compiler Visualizer" is now available for download from

The tool visualizes the internal data structures of the client compiler
(also called C1), both textually and graphically. It uses information that
can be emitted by the debug version of the Java HotSpot VM since version 6,
including the OpenJDK.
The application can be useful for all developers that work on the client
compiler, i.e. if you port it to a new platform or develop new compiler

Feel free to contact me if you have questions or comments.
