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 (by default, hotspot_pid{pid}.log) from LogCompilation output like this: 8 9 java -jar logc.jar hotspot_pid1234.log 10 11 This will produce something like the normal PrintCompilation output. 12 Adding the -i option with also report inlining like PrintInlining. 13 14 More information about the LogCompilation output can be found at 15 16 https://wiki.openjdk.java.net/display/HotSpot/LogCompilation+overview 17 https://wiki.openjdk.java.net/display/HotSpot/PrintCompilation 18 https://wiki.openjdk.java.net/display/HotSpot/LogCompilation+tool
