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

|
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. |
