A partial fragment deoptimization will deopt a\nsingle frame, or all frames up to the method that\u0027s not deoptimizeable,\nand then jumps to the interpreter bridge.\n\nCurrently code not deoptimizeable is the code in boot image since the\ncode may not be compiled with debuggable flag.\n\nBug: 28769520\nChange-Id: I875c694791cc8ebd5121abcd92ce7b0db95aca38\n" }, { "commit": "3c7787fb2e197934a0e87329644384445b1d062f", "tree": "5942b3faa6b23abdccb98a2f9b9a13fa75ca6d36", "parents": [ "80fd43eead361bd3b61d646e5c8efcdd0720304d", "fba39972d99701c80bf3beb7451aca508d67593c" ], "author": { "name": "Treehugger Robot", "email": "treehugger-gerrit@google.com", "time": "Tue May 24 18:19:35 2016 +0000" }, "committer": { "name": "Gerrit Code Review", "email": "noreply-gerritcodereview@google.com", "time": "Tue May 24 18:19:35 2016 +0000" }, "message": "Merge \"Fix misc-macro-parentheses warnings.\"" }, { "commit": "31e61f1d0aeb2c85ebddc7cd0cc3d7f1aea4014e", "tree": "7c0b766c39ba378e8f07be134291cc1ee38ba66e", "parents": [ "73660f87497cadb77e8b33b4f5e01c34baae00dc", "84a4ab827685b10088eb01807b1e9296bec527b3" ], "author": { "name": "Evgenii Stepanov", "email": "eugenis@google.com", "time": "Mon May 16 20:17:17 2016 +0000" }, "committer": { "name": "Gerrit Code Review", "email": "noreply-gerritcodereview@google.com", "time": "Mon May 16 20:17:17 2016 +0000" }, "message": "Merge \"SafeStack-friendly stack protection in ART.\"" }, { "commit": "84a4ab827685b10088eb01807b1e9296bec527b3", "tree": "a7f1b57a95282505999045a7c052709c74e1b62f", "parents": [ "30ad1c2e8b43227c28a6870c8c9eb765b80b0b33" ], "author": { "name": "Evgenii Stepanov", "email": "eugenis@google.com", "time": "Fri May 13 14:01:41 2016 -0700" }, "committer": { "name": "Evgenii Stepanov", "email": "eugenis@google.com", "time": "Mon May 16 11:14:39 2016 -0700" }, "message": "SafeStack-friendly stack protection in ART.\n\nThis code takes an address of a stack variable to find the current\nstack top.

Structural inefficiencies (primarily the bloated\n fetch/decode/execute overhead of the C++ interpreter\n implementation).\n2. Stack memory wastage. Each managed-language invoke\n adds a full copy of the interpreter\u0027s compiler-generated\n locals on the shared stack. We\u0027re at the mercy of\n the compiler now in how much memory is wasted here. An\n assembly based interpreter can manage memory usage more\n effectively.\n3. Shadow frame model, which not only spends twice the memory\n to store the Dalvik virtual registers, but causes vreg stores\n to happen twice.\n\nThis CL mostly deals with #1 (but does provide some stack memory\nsavings). Subsequent CLs will address the other issues.\n\nCurrent status:\n Passes all run-tests.\n Phone boots interpret-only.\n 2.5x faster than Clang-compiled Art goto interpreter on fetch/decode/execute\n microbenchmark, 5x faster than gcc-compiled goto interpreter.\n 1.6x faster than Clang goto on Caffeinemark overall\n 2.0x faster than Clang switch on Caffeinemark overall\n 68% of Dalvik interpreter performance on Caffeinemark (still much slower,\n primarily because of poor invoke performance and lack of execute-inline)\n Still nearly an order of magnitude slower than Dalvik on invokes\n (but slightly better than Art Clang goto interpreter.\n Importantly, saves ~200 bytes of stack memory per invoke (but still\n wastes ~400 relative to Dalvik).\n\nWhat\u0027s needed:\n Remove the (large quantity of) bring-up hackery in place.\n Integrate into the build mechanism. I\u0027m still using the old Dalvik manual\n build step to generate assembly code from the stub files.\n Remove the suspend check hack. For bring-up purposes, I\u0027m using an explicit\n suspend check (like the other Art interpreters). However, we should be\n doing a Dalvik style suspend check via the table base switch mechanism.\n This should be done during the alternative interpreter activation.\n General cleanup.\n Add CFI info.\n Update the new target bring-up README documentation.\n Add other targets.\n\nIn later CLs:\n Consolidate mterp handlers for expensive operations (such as new-instance) with\n the code used by the switch interpreter. No need to duplicate the code for\n heavyweight operations (but will need some refactoring to align).\n Tuning - some fast paths needs to be moved down to the assembly handlers,\n rather than being dealt with in the out-of-line code.\n JIT profiling. Currently, the fast interpreter is used only in the fast\n case - no instrumentation, no transactions and no access checks. We\n will want to implement fast + JIT-profiling as the alternate fast\n interpreter. All other cases can still fall back to the reference\n interpreter.\n Improve invoke performance. We\u0027re nearly an order of magnitude slower than\n Dalvik here. Some of that is unavoidable, but I suspect we can do\n better.\n Add support for our other targets.\n\nChange-Id: I43e25dc3d786fb87245705ac74a87274ad34fedc\n" }, { "commit": "7c1559a06041c9c299d5ab514d54b2102f204a84", "tree": "c50b54bf82f457f44dbf0741947d836749d4a96a", "parents": [ "7cd230c8f74a227ea04f1dd93c8d855aa81fc1fe" ], "author": { "name": "Roland Levillain", "email": "rpl@google.com", "time": "Tue Dec 15 10:55:36 2015 +0000" }, "committer": { "name": "Roland Levillain", "email": "rpl@google.com", "time": "Tue Dec 15 11:45:56 2015 +0000" }, "message": "x86 Baker\u0027s read barrier fast path implementation.\n\nIntroduce an x86 fast path implementation in Optimizing for\nBaker\u0027s read barriers (for both heap reference loads and GC\nroot loads).

improves the JNI performance by removing the explicit acquiring and\nreleasing the mutator lock when a thread state transits between suspended and\nrunnable states.\n\nThe functions responsible for changing the state were found to be the costliest\npart of the JNI. Originally, a thread needs to acquire a shared mutator lock by\na CAS instruction when entering the runnable state and also needs to release\nthe lock by a CAS when entering the native state from runnable. This patch\nremoves these CAS operations when a thread state transits between suspended and\nrunnable. A thread in the runnable state is considered to have shared ownership\nof the mutator lock and therefore transitions in and out of the runnable state\nhave associated implication on the mutator lock ownership. Meanwhile, a barrier\nis added to control suspending all threads from running.\n\nJNI transition overhead was reduced by 25% on IA platform and by 17% on ARM\nplatform by this patch, while it has little impact on GC pause time (measured\nwith \"suspend all histogram\").\n\nChange-Id: Icee95d8ffff1bbfc95309a41cc48836536fec689\nSigned-off-by: Yu, Li \u003cyu.l.li@intel.com\u003e\nSigned-off-by: Haitao, Feng \u003chaitao.feng@intel.com\u003e\nSigned-off-by: Lei, Li \u003clei.l.li@intel.com\u003e\n" }, { "commit": "5b1eea0a6c90e6e82393cdb7337f0c2bb05637d9", "tree": "3b8bddd878f07ee418a83a09f229ea44f2a20a05", "parents": [ "24db1bc55bf8fb3240690436a229352453ae75e1", "0b71357fb52be9bb06d35396a3042b4381b01041" ], "author": { "name": "Hiroshi Yamauchi", "email": "yamauchi@google.com", "time": "Mon Jul 13 22:51:39 2015 +0000" }, "committer": { "name": "Gerrit Code Review", "email": "noreply-gerritcodereview@google.com", "time": "Mon Jul 13 22:51:40 2015 +0000" }, "message": "Merge \"Thread-local mark stacks for the CC collector.\"" }, { "commit": "0b71357fb52be9bb06d35396a3042b4381b01041", "tree": "44b8d6b0ca4a71f33cda55068fa9e14864c55625", "parents": [ "0e87d1809443d41b431ce3a686b4e074df2d7b8b" ], "author": { "name": "Hiroshi Yamauchi", "email": "yamauchi@google.com", "time": "Tue Jun 16 18:29:23 2015 -0700" }, "committer": { "name": "Hiroshi Yamauchi", "email": "yamauchi@google.com", "time": "Mon Jul 13 15:50:20 2015 -0700" }, "message": "Thread-local mark stacks for the CC collector.\n\nThread-local mark stacks are assigned to mutators where they push\nreferences in read barriers to reduce the (CAS) synchronization cost\nin a global mark stack/queue.\n\nWe step through three mark stack modes (thread-local, shared,\nGC-exclusive) and use per-thread flags to disable/enable system weak\naccesses (only for the CC collector) instead of the existing global\none to safely perform the marking phase.

But doing that prevents the JDWP thread\nfrom processing incoming commands from the debugger if the event\nthread gets suspended by a debug event occurring in another thread.\nIn Android Studio (or another IDE), this leads to the debugger being\nblocked (with the famous message \"Waiting until last debugger command\ncompletes\" of Android Studio / IntelliJ) because it is actually\nwaiting for the reply of its latest command while the JDWP thread\ncannot process it.\n\nThis CL changes the way invoke commands (ClassType.InvokeCommand,\nClassType.NewInstance and ObjectReference.InvokeCommand) are handled\nin the ART runtime.\nThe JDWP thread no longer waits for the event thread to complete the\nmethod invocation. It now simply waits for the next JDWP command to\nprocess. This means it does not send any reply for invoke commands,\nexcept if the information given by the debugger is wrong. In this\ncase, it still sends a reply with the appropriate error code.\nThe event thread is now responsible for sending the reply (containing\nthe result and the exception object of the invoked method) before\ngoing back to the suspended state.\n\nIn other words, we add special handling for invoke commands so they\nare handled asynchronously while other commands remained handled\nsynchronously. In the future, we may want to handle all commands\nasynchronously (using a queue of reply/event for instance) to remove\nthe special handling code this CL is adding.\n\nNow the JDWP thread can process commands while a thread is invoking\na method, it is possible for the debugger to detach (by sending a\nVirtualMachine.Dispose command) before the invocation completes. In\nthat situation, we must not suspend threads again (including the\nevent thread that executed the method) because they would all remain\nsuspended forever.\n\nAlso minor cleanup of the use of JDWP constants and update comments.\n\nBug: 21515842\nBug: 18899981\nChange-Id: I15e00fb068340f3d69dc9225d8d2065246e68c58\n" } ], "next": "f795869da0a1fa006fdcdacd8afb6149a63fc1a7" }
