| 1 This is a very rough tool for parsing -XX:+LogCompilation output. | |
| 2 It's main purpose is to recreate output similar to | |
| 3 -XX:+PrintCompilation -XX:+PrintInlining output from a debug JVM. It | |
| 4 requires a 1.5 JDK to build and simply typing make should build it. | |
| 5 | |
| 6 It produces a jar file, logc.jar, that can be run on the | |
| 7 hotspot.log from LogCompilation output like this: | |
| 8 | |
| 9 java -jar logc.jar hotspot.log | |
| 10 | |
| 11 This will produce something like the normal PrintCompilation output. | |
| 12 Adding the -i option with also report inlining like PrintInlining. | |
| 13 | |
