Subject [jira] Updated: (HARMONY-2012) [drlvm][em] value-profling implemenation
Date Wed, 06 Dec 2006 16:28:23 GMT
     [ http://issues.apache.org/jira/browse/HARMONY-2012?page=all ]

Pavel Ozhdikhin updated HARMONY-2012:
-------------------------------------

    Attachment: patch_20061206.zip

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 Jitrino.OPT
 - -Xem:server mode updated to gather/use value profile

The patch is not final - it passes tests on Windows but it doesn't work on Linux yet.
Please review and comment.
