| 1194 // are set or it has already been compiled. Thus there can not be two | |
| 1195 // instances of a compilation task for the same method on the | |
| 1196 // compilation queue. Consider now the case where the compilation | |
| 1197 // thread has already removed a task for that method from the queue | |
| 1198 // and is in the midst of compiling it. In this case, the | |
| 1199 // queued_for_compile bits must be set in the method (and these | |
| 1200 // will be visible to the current thread, since the bits were set | |
| 1201 // under protection of the compile queue lock, which we hold now. | |
| 1202 // When the compilation completes, the compiler thread first sets | |
| 1203 // the compilation result and then clears the queued_for_compile | |
| 1204 // bits. Neither of these actions are protected by a barrier (or done | |
| 1205 // under the protection of a lock), so the only guarantee we have | |
| 1206 // (on machines with TSO (Total Store Order)) is that these values | |
| 1207 // will update in that order. As a result, the only combinations of | |
| 1208 // these bits that the current thread will see are, in temporal order: | |
| 1209 // <RESULT, QUEUE> : | |
| 1210 // <0, 1> : in compile queue, but not yet compiled | |
| 1211 // <1, 1> : compiled but queue bit not cleared | |
| 1212 // <1, 0> : compiled and queue bit cleared | |
| 1213 // Because we first check the queue bits then check the result bits, | |
| 1214 // we are assured that we cannot introduce a duplicate task. | |
| 1215 // Note that if we did the tests in the reverse order (i.e. check | |
| 1216 // result then check queued bit), we could get the result bit before | |
| 1217 // the compilation completed, and the queue bit after the compilation | |
| 1218 // completed, and end up introducing a "duplicate" (redundant) task. | |
| 1219 // In that case, the compiler thread should first check if a method | |
| 1220 // has already been compiled before trying to compile it. | |
| 1221 // NOTE: in the event that there are multiple compiler threads and | |
