code review request for JVM/TI CompiledMethodLoad event extension (6580131)

[Daniel D. Daugherty]

Greetings,

The folks at AMD Labs have been kind enough to provide an
extension to the JVM/TI CompileMethodLoad event in order
to provide additional information about in-lining. This
extension uses the existing (but previously unused)
compile_info paramter:

http://java.sun.com/javase/6/docs/platform/jvmti/jvmti.html#CompiledMethodLoad

Vasanth and company provided the HotSpot code changes and
the original demo program. I just did the Makefile changes
to export the new jvmticmlr.h file in the HotSpot repo and
the integration of the demo program into JAVA_HOME/demo/jvmti
in the JDK repo.

Here is the webrev for the OpenJDK6 version of the changes:

The OpenJDK7 version of these changes are not expected to be
very different from this version.

For the Sun folks, the CCC request for adding the jvmticmlr.h
is almost final. I'm waiting for the VM-SQE team to agree that
the latest version addresses their review concerns, but I
think the St Petersburg team is on holiday at the moment.

Any reviews are appreciated.

Dan
