[jira] Created: (HARMONY-2057) [drlvm][jit] Jitrino.OPT's bpp.version=6 algorithm (the default) considers that all VM helpers are interruptable.

[drlvm][jit] Jitrino.OPT's bpp.version=6 algorithm (the default) considers that all VM helpers are interruptable.
-----------------------------------------------------------------------------------------------------------------

                 Key: HARMONY-2057
                 URL: http://issues.apache.org/jira/browse/HARMONY-2057
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
            Reporter: Mikhail Fursov


Run SyncTest using 2 different bbp algorithms:

For BBP.version=1 (needs HARMONY-2056 to work correctly)
java.exe -Xem:opt -Djit. f.arg.codegen.bbp.version=1  -Djit.CS_OPT.f.filter=Waiter::run -Djit.f.arg.log=ct,irdump,dotdump -Djit.CS_OPT.arg.optimizer.inliner=off SyncTest
waiter started..
stopper started..
stopping..
inside finish()..
stopped..
passed!

For BBP.version=6
java.exe -Xem:opt -Djit. f.arg.codegen.bbp.version=6  -Djit.CS_OPT.f.filter=Waiter::run -Djit.f.arg.log=ct,irdump,dotdump -Djit.CS_OPT.arg.optimizer.inliner=off SyncTest
waiter started..
.....(hangs..)

If you check the IR you will see that for version=6 there was no BBP code insertion into the loop with monenter and monexit helpers.
