This would cause the test to fail as the\nquick_to_interpreter_bridge frame prevented deoptimization of the\nobsoleted function. Usually the warm-up period was enough to make sure\nthe methods were jitted anyway but this was not guaranteed.\n\nBoth of these problems become more likely to occur on systems with\nmore cpu contention such as the buildbots.\n\nTest: stress --cpu 60 \u0026; while ./test/run-test --host --jit 916; do ; done\n\nReason for revert: Fixed bug in test that was causing failures.\n\nOriginal Tests:\n\nTest: ./test/run-test --host 914\nTest: ./test/run-test --host 915\nTest: ./test/run-test --host 916\nTest: mma -j40 test-art-host\nTest: ART_TEST_JIT\u003dtrue \\\n      ART_TEST_INTERPRETER\u003dtrue mma -j40 test-art-host\nTest: ./art/tools/run-jdwp-tests.sh --mode\u003dhost --variant\u003dX64\nTest: ./art/tools/run-jdwp-tests.sh --mode\u003dhost --variant\u003dX64 --no-jit\n\nBug: 32369913\nBug: 33630159\n\nChange-Id: If1a92e47b90965a7dc21c5826185debe62bd1554\n"

      "message": "ART: Fix race in on-stack replacement\n\nThe expected sequence of events for on-stack replacement is:\n\n   1. Method goes warm, triggering enhanced profiling\n   2. Method goes hot, triggering method compilation\n   3. Method goes really hot, triggering an osr method compilation.\n   4. Interpreter polls for the existence of an osr entry point,\n      and transitons to compiled code if found.\n\nWe have a race problem if #2 and #3 happen closely together, and\nthe osr method compilation begins before the regular method\ncompilation.  In that case, the jit sees that the method is\nalready being compiled (the osr method - but it does not\ndistinguish the two), and discards the normal compilation request.\nSo, the osr version is compiled and the normal version is discarded.\nIn #4, the MaybeDoOnStackReplacement() check assumes that a normal\nversion of the compiled method must exist before doing an on-stack\nreplacement, so it keeps returning false.\n\nThis is why we were seeing sporadic timeout failures of\n570-checker-osr when the mterp fast branch profiling was\nintroduced.  The branch profiling performance enhancements\ngreatly reduced the time between #2 and #3, increasing the liklihood\nof losing the race.  Further, the new code clamped hotness to avoid\nwrap-around.  The race existed (and likely occurred) in the previous\nversion, but because hotness counters were allowed to overflow and\nwrap around you\u0027d eventually hit the threshold a second time and\ntry again - masking the problem.\n\nTip \u0027o the hat to Serguei Katkov for identifying the problem.\n\nA possible solution (taken in this CL) is to differentiate osr\ncompilations from normal method compilations.\n\nBug: 27939339\nChange-Id: I71044516b35dc69de9fc2d2a445e33809ac650ed\n"

      "message": "Fix very rare bug around JIT code cache collection.\n\nThe bug is the following:\n1) JIT thread: We start a code cache collection.\n2) JIT thread: We mark all code that is in the call stack of all\n   threads.\n3) Mutator thread: after marking its stack, resumes and does call\n   that pushes JIT compiled code to the call stack.\n4) Mutator thread: deoptimizes compiled code of ArtMethod Foo,\n   and therefore updates the entry point of Foo through\n   JitCodeCache::InvalidateCompiledCodeFor.\n   (Note that updating the entrypoint could also be done through\n   instrumentation).\n5) JIT thread: Call JitCodeCache::RemoveUnusedAndUnmarkedCode.\n   The method used to remove entries that were not entrypoints.\n   It sees the compiled code for Foo but that is not an entrypoint\n   anymore, so deletes it.\n6) Mutator thread problem: it now has compiled code in its call\n   stack that is deleted.\n\nIf it\u0027s only one mutator thread, we only hit a DCHECK when walking\nthe stack, as we are now seeing an invalid pc. The deoptimization\nwill longjmp to the caller of that invalid entry anyway.\n\nHowever, if multiple mutator threads are involved, one thread\nmight invalidate the compiled code while the other is still\nrunning it. And we end up deleting code that is in the call\nstack of a thread, and we will crash.\n\nThe fix is to mark entrypoints before marking call stacks,\nso that anything a thread might jump to is marked and kept.\n\nbug:27424509\nbug:23128949\nbug:26846185\n\nChange-Id: I07cd08cedd96b9900629f7535e95404f622104ea\n"
