| 1222 // queued for compilation more than once, as follows: | |
| 1223 // Before a thread queues a task for compilation, it first acquires | |
| 1224 // the compile queue lock, then checks if the method's queued bits | |
| 1225 // are set or it has already been compiled. Thus there can not be two | |
| 1226 // instances of a compilation task for the same method on the | |
| 1227 // compilation queue. Consider now the case where the compilation | |
| 1228 // thread has already removed a task for that method from the queue | |
| 1229 // and is in the midst of compiling it. In this case, the | |
| 1230 // queued_for_compile bits must be set in the method (and these | |
| 1231 // will be visible to the current thread, since the bits were set | |
| 1232 // under protection of the compile queue lock, which we hold now. | |
| 1233 // When the compilation completes, the compiler thread first sets | |
| 1234 // the compilation result and then clears the queued_for_compile | |
| 1235 // bits. Neither of these actions are protected by a barrier (or done | |
| 1236 // under the protection of a lock), so the only guarantee we have | |
| 1237 // (on machines with TSO (Total Store Order)) is that these values | |
| 1238 // will update in that order. As a result, the only combinations of | |
| 1239 // these bits that the current thread will see are, in temporal order: | |
| 1240 // <RESULT, QUEUE> : | |
| 1241 // <0, 1> : in compile queue, but not yet compiled | |
| 1242 // <1, 1> : compiled but queue bit not cleared | |
| 1243 // <1, 0> : compiled and queue bit cleared | |
| 1244 // Because we first check the queue bits then check the result bits, | |
| 1245 // we are assured that we cannot introduce a duplicate task. | |
| 1246 // Note that if we did the tests in the reverse order (i.e. check | |
| 1247 // result then check queued bit), we could get the result bit before | |
