        Is there any chance to get this code instrumentation:

        1. based on recent version of Harmony DRLVM?

        2. in the patch form to be reviewed?

        If this instrumentation is already out of interest then let's fget this JIRA resolved as WON'T FIXED.

        I would also like to see if there are any patches in this issue. The packed source tree for VM is really outdated and it is hard to understand the actual changes done to the code.

        As far as I can understand DPGO is a part of JIT, so marking this as a JIT issue.
