1160 // Before a thread queues a task for compilation, it first acquires | |
1161 // the compile queue lock, then checks if the method's queued bits | |
1162 // are set or it has already been compiled. Thus there can not be two | |
1163 // instances of a compilation task for the same method on the | |
1164 // compilation queue. Consider now the case where the compilation | |
1165 // thread has already removed a task for that method from the queue | |
1166 // and is in the midst of compiling it. In this case, the | |
1167 // queued_for_compile bits must be set in the method (and these | |
1168 // will be visible to the current thread, since the bits were set | |
1169 // under protection of the compile queue lock, which we hold now. | |
1170 // When the compilation completes, the compiler thread first sets | |
1171 // the compilation result and then clears the queued_for_compile | |
1172 // bits. Neither of these actions are protected by a barrier (or done | |
1173 // under the protection of a lock), so the only guarantee we have | |
1174 // (on machines with TSO (Total Store Order)) is that these values | |
1175 // will update in that order. As a result, the only combinations of | |
1176 // these bits that the current thread will see are, in temporal order: | |
1177 // <RESULT, QUEUE> : | |
1178 // <0, 1> : in compile queue, but not yet compiled | |
1179 // <1, 1> : compiled but queue bit not cleared | |
1180 // <1, 0> : compiled and queue bit cleared | |
1181 // Because we first check the queue bits then check the result bits, | |
1182 // we are assured that we cannot introduce a duplicate task. | |
1183 // Note that if we did the tests in the reverse order (i.e. check | |
1184 // result then check queued bit), we could get the result bit before | |
1185 // the compilation completed, and the queue bit after the compilation | |
1186 // completed, and end up introducing a "duplicate" (redundant) task. | |
1187 // In that case, the compiler thread should first check if a method | |
1188 // has already been compiled before trying to compile it. | |
1189 // NOTE: in the event that there are multiple compiler threads and | |
