This is a very rough tool for parsing -XX:+LogCompilation output. It's main purpose is to recreate output similar to -XX:+PrintCompilation -XX:+PrintInlining output from a debug JVM. It requires a 1.5 JDK to build and simply typing make should build it. It produces a jar file, logc.jar, that can be run on the HotSpot log (by default, hotspot_pid{pid}.log) from LogCompilation output like this: java -jar logc.jar hotspot_pid1234.log This will produce something like the normal PrintCompilation output. Adding the -i option with also report inlining like PrintInlining. More information about the LogCompilation output can be found at https://wikis.oracle.com/display/HotSpotInternals/LogCompilation+overview https://wikis.oracle.com/display/HotSpotInternals/PrintCompilation https://wikis.oracle.com/display/HotSpotInternals/LogCompilation+tool
