Subject [drlvm][em/jit] updated implementation of value profiling, interface devirtualization etc.
Date Wed, 06 Dec 2006 16:37:43 GMT

I have updated Harmony-2012<http://issues.apache.org/jira/browse/HARMONY-2012?page=all>
value-profling implemenation" with the fresh patch.
 The patch contains the following:

 - updated value profiling framework initially created by Yuri (per-method
locks added, value type adjusted, several bugs fixed),
 - value profiling support in Jitrino.OPT,
 - ExecutionManager updated to support several profile collectors at once
 - Interface devirtualization based on the value profile is implemented in
 - -Xem:server mode updated to gather/use value profile

 If you have some experience in ExectionManager, ProfileCollectors and JIT
please review the patch and comment in JIRA.
The patch is not final - it passes tests on Windows/IA32 but it doesn't work
on Linux/IA32 yet.
Still can't run on Linux/EM64T because build is broken there.

Thank you,
