Subject [jira] Updated: (HARMONY-1406) [drlvm][jit] instrument to profile the memory access pattern
Date Thu, 04 Oct 2007 14:47:50 GMT

     [ https://issues.apache.org/jira/browse/HARMONY-1406?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Gregory Shimansky updated HARMONY-1406:
---------------------------------------

    Summary: [drlvm][jit] instrument to profile the memory access pattern  (was: [drlvm] instrument
to profile the memory access pattern)

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VM is really outdated and it is hard to understand the actual changes done to the code.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.
