| 1113 // the target method. We can now reason that a method cannot be | |
| 1114 // queued for compilation more than once, as follows: | |
| 1115 // Before a thread queues a task for compilation, it first acquires | |
| 1116 // the compile queue lock, then checks if the method's queued bits | |
| 1117 // are set or it has already been compiled. Thus there can not be two | |
| 1118 // instances of a compilation task for the same method on the | |
| 1119 // compilation queue. Consider now the case where the compilation | |
| 1120 // thread has already removed a task for that method from the queue | |
| 1121 // and is in the midst of compiling it. In this case, the | |
| 1122 // queued_for_compile bits must be set in the method (and these | |
| 1123 // will be visible to the current thread, since the bits were set | |
| 1124 // under protection of the compile queue lock, which we hold now. | |
| 1125 // When the compilation completes, the compiler thread first sets | |
| 1126 // the compilation result and then clears the queued_for_compile | |
| 1127 // bits. Neither of these actions are protected by a barrier (or done | |
| 1128 // under the protection of a lock), so the only guarantee we have | |
| 1129 // (on machines with TSO (Total Store Order)) is that these values | |
| 1130 // will update in that order. As a result, the only combinations of | |
| 1131 // these bits that the current thread will see are, in temporal order: | |
| 1132 // <RESULT, QUEUE> : | |
| 1133 // <0, 1> : in compile queue, but not yet compiled | |
| 1134 // <1, 1> : compiled but queue bit not cleared | |
| 1135 // <1, 0> : compiled and queue bit cleared | |
| 1136 // Because we first check the queue bits then check the result bits, | |
| 1137 // we are assured that we cannot introduce a duplicate task. | |
| 1138 // Note that if we did the tests in the reverse order (i.e. check | |
| 1139 // result then check queued bit), we could get the result bit before | |
| 1140 // the compilation completed, and the queue bit after the compilation | |
| 1141 // completed, and end up introducing a "duplicate" (redundant) task. | |
| 1142 // In that case, the compiler thread should first check if a method | |
| 1143 // has already been compiled before trying to compile it. | |
| 1144 // NOTE: in the event that there are multiple compiler threads and | |
| 1145 // there is de-optimization/recompilation, things will get hairy, | |
| 1146 // and in that case it's best to protect both the testing (here) of | |
| 1147 // these bits, and their updating (here and elsewhere) under a | |
| 1148 // common lock. | |
