Subject [jira] Created: (HARMONY-2160) BackBranchPolling can be omitted for final loops

BackBranchPolling can be omitted for final loops
------------------------------------------------

                 Key: HARMONY-2160
                 URL: http://issues.apache.org/jira/browse/HARMONY-2160
             Project: Harmony
          Issue Type: Improvement
          Components: DRLVM
            Reporter: George Timoshenko
            Priority: Minor


BackBranchPolling allows to interrupt threads that are executing an infinite or very long
loops. (For example for garbage collection)
But sometimes this is reduntant, if a loop is finite and it is not very large.

For example: Jitrino.OPT can optimize System.arraycopy(...) call into manually generated loop.
It is obvious that the loop is finite. (it copies finite number of elements from one array
into another one)
