| 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. |
| |

| |
| The project layout is now for Maven. To build the project with Maven do: |
| |
| mvn clean install |
| |
| The build also copies the resulting target jar to ./logc.jar for easy |
| interop with the Makefile build. |
