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 from LogCompilation output like this:
|
|
|
|
java -jar logc.jar hotspot.log
|
|
|
|
This will produce something like the normal PrintCompilation output.
|
|
Adding the -i option with also report inlining like PrintInlining.
|
|
|
|
