1388 // Before a thread queues a task for compilation, it first acquires | |
1389 // the compile queue lock, then checks if the method's queued bits | |
1390 // are set or it has already been compiled. Thus there can not be two | |
1391 // instances of a compilation task for the same method on the | |
1392 // compilation queue. Consider now the case where the compilation | |
1393 // thread has already removed a task for that method from the queue | |
1394 // and is in the midst of compiling it. In this case, the | |
1395 // queued_for_compile bits must be set in the method (and these | |
1396 // will be visible to the current thread, since the bits were set | |
1397 // under protection of the compile queue lock, which we hold now. | |

1399 // the compilation result and then clears the queued_for_compile | |

1401 // under the protection of a lock), so the only guarantee we have | |
1402 // (on machines with TSO (Total Store Order)) is that these values | |
1403 // will update in that order. As a result, the only combinations of | |
1404 // these bits that the current thread will see are, in temporal order: | |
1405 // <RESULT, QUEUE> : | |
1406 // <0, 1> : in compile queue, but not yet compiled | |
1407 // <1, 1> : compiled but queue bit not cleared | |
1408 // <1, 0> : compiled and queue bit cleared | |

1414 // completed, and end up introducing a "duplicate" (redundant) task. | |
