| 1387 // 14012000: Note that this sets the queued_for_compile bits in | |
| 1388 // the target method. We can now reason that a method cannot be | |
| 1389 // queued for compilation more than once, as follows: | |
| 1390 // Before a thread queues a task for compilation, it first acquires | |
| 1391 // the compile queue lock, then checks if the method's queued bits | |
| 1392 // are set or it has already been compiled. Thus there can not be two | |
| 1393 // instances of a compilation task for the same method on the | |
| 1394 // compilation queue. Consider now the case where the compilation | |
| 1395 // thread has already removed a task for that method from the queue | |
| 1396 // and is in the midst of compiling it. In this case, the | |
| 1397 // queued_for_compile bits must be set in the method (and these | |
| 1398 // will be visible to the current thread, since the bits were set | |
| 1399 // under protection of the compile queue lock, which we hold now. | |
| 1400 // When the compilation completes, the compiler thread first sets | |
| 1401 // the compilation result and then clears the queued_for_compile | |
| 1402 // bits. Neither of these actions are protected by a barrier (or done | |
| 1403 // under the protection of a lock), so the only guarantee we have | |
| 1404 // (on machines with TSO (Total Store Order)) is that these values | |
| 1405 // will update in that order. As a result, the only combinations of | |
| 1406 // these bits that the current thread will see are, in temporal order: | |
| 1407 // <RESULT, QUEUE> : | |
| 1408 // <0, 1> : in compile queue, but not yet compiled | |
| 1409 // <1, 1> : compiled but queue bit not cleared | |
| 1410 // <1, 0> : compiled and queue bit cleared | |
| 1411 // Because we first check the queue bits then check the result bits, | |
| 1412 // we are assured that we cannot introduce a duplicate task. | |
| 1413 // Note that if we did the tests in the reverse order (i.e. check | |
| 1414 // result then check queued bit), we could get the result bit before | |
| 1415 // the compilation completed, and the queue bit after the compilation | |
| 1416 // completed, and end up introducing a "duplicate" (redundant) task. | |
| 1417 // In that case, the compiler thread should first check if a method | |
| 1418 // has already been compiled before trying to compile it. | |
| 1419 // NOTE: in the event that there are multiple compiler threads and | |
| 1420 // there is de-optimization/recompilation, things will get hairy, | |
| 1421 // and in that case it's best to protect both the testing (here) of | |
