It uses\nthe new DeoptimizeStackVisitor class to create shadow frames.\n\nWe also add the Thread::GetDeoptimizationException method to get the definition\nof the fake exception in only one place.\n\nChange-Id: I01b19fa72af64329b5c3b6c7f0c3339d2d724978\n" }, { "commit": "4af159bfcc66c6e90a2aee4a2035a996a399e7ed", "tree": "9bc7f4ac4f6ce93be0e9f2bc8db6ccdb9d972c36", "parents": [ "d299898a55f41ccf78b865e153ae91321229353b", "987560fee798e48fb725c44b796d8ca7a5872ad6" ], "author": { "name": "Ian Rogers", "email": "irogers@google.com", "time": "Tue Apr 22 23:03:01 2014 +0000" }, "committer": { "name": "Gerrit Code Review", "email": "noreply-gerritcodereview@google.com", "time": "Tue Apr 22 23:03:01 2014 +0000" }, "message": "Merge \"Remove support for app JNI workarounds.\"" }, { "commit": "987560fee798e48fb725c44b796d8ca7a5872ad6", "tree": "d61f35a129847f3f5fbed1436649e75acd940b3f", "parents": [ "44b0053fdb7ad8a30138d29f714172a7dc69efb8" ], "author": { "name": "Ian Rogers", "email": "irogers@google.com", "time": "Tue Apr 22 11:42:59 2014 -0700" }, "committer": { "name": "Ian Rogers", "email": "irogers@google.com", "time": "Tue Apr 22 14:52:19 2014 -0700" }, "message": "Remove support for app JNI workarounds.\n\nChange-Id: I4396df7e93fcace4b5b19c2c387e5c30089182a6\n" }, { "commit": "a2cee18799d7e61adb037a4219adb23fef7d022b", "tree": "214a6d6d4682196aa0e2ebcb5a0cc7bcf3eec2d3", "parents": [ "ed0bc0bbf26f6751f31213d24ccdac49766e93ff" ], "author": { "name": "Christopher Ferris", "email": "cferris@google.com", "time": "Wed Apr 16 19:13:59 2014 -0700" }, "committer": { "name": "Christopher Ferris", "email": "cferris@google.com", "time": "Fri Apr 18 15:32:15 2014 -0700" }, "message": "Modify unwind to comply with stack parser tools.\n\nBug: 14081592\n\nChange-Id: I6906b2575c74d64f1c3ba7602779b3a789de1c69\n" }, { "commit": "4d7f61d44a732cfbc8573e5d93364983fd746888", "tree": "0ad34f9316227531696c01ba9b25a2175a5c5f65", "parents": [ "425640d6fac3432a44e236a002e8401a7cd59c5c" ], "author": { "name": "Mathieu Chartier", "email": "mathieuc@google.com", "time": "Thu Apr 17 14:43:39 2014 -0700" }, "committer": { "name": "Mathieu Chartier", "email": "mathieuc@google.com", "time": "Thu Apr 17 15:56:47 2014 -0700" }, "message": "Use non volatile lock words in semispace collector.\n\nGSS FormulaEvaluationActions.EvaluateAndApplyChanges:\nBefore GC time: 9.1s\nAfter GC time: 7.98s\n\nFixed timing logger errors.\n\nChange-Id: I4193c6ccbbbe7a7220dfaabbf3472a5dcebae616\n" }, { "commit": "63e8a68c9a2cdbbe9bfd8d200610119dd359ee59", "tree": "144c911b7d8da5b0047a5ce3f340de73cdc8b56d", "parents": [ "a3eaf66b968270b938a2795fe55e778c55f1c24b" ], "author": { "name": "Yevgeny Rouban", "email": "yevgeny.y.rouban@intel.com", "time": "Wed Apr 16 18:26:09 2014 +0700" }, "committer": { "name": "Yevgeny Rouban", "email": "yevgeny.y.rouban@intel.com", "time": "Wed Apr 16 18:26:09 2014 +0700" }, "message": "Fix thread join hangs\n\nCurrent implementation notifies only one of joining threads on thread exit.\nThis causes the other joining threads to hang.\n\nThis patch notifies all joining threads: just call NotifyAll() instead of Notify().\n\nChange-Id: If75f101d3d3d876f1aa7dcf537e56a37cc347803\nSigned-off-by: Yevgeny Rouban \u003cyevgeny.y.rouban@intel.com\u003e\n" }, { "commit": "c7a966dbba6902618ff0959d604c05d7570df8c8", "tree": "9c29dc008ad24e97ba26d5734fc7db4a41f7ca52", "parents": [ "22839a631bb3591a1c0037c388d51a4f18b5fb5e" ], "author": { "name": "Mathieu Chartier", "email": "mathieuc@google.com", "time": "Thu Apr 10 18:06:32 2014 -0700" }, "committer": { "name": "Mathieu Chartier", "email": "mathieuc@google.com", "time": "Thu Apr 10 18:07:46 2014 -0700" }, "message": "Prevent deadlocks in Runtime::Abort.\n\nIf we have the threads suspended, attempting to use a\nScopedObjectAccess causes a deadlock.

This only\nconcerns class initialization happening at compilation time when generating an\nimage (like boot.art for the system).\n\nIn transactional mode, we log every object\u0027s field assignment and array update.\nTherefore we\u0027re able to abort a transaction to restore values of fields and\narray as they were before the transaction starts. We also log changes to the\nintern string table so we can restore its state prior to transaction start.\n\nSince transactional mode only happens at compilation time, we don\u0027t need to log\nall these changes at runtime. In order to reduce the overhead of testing if\ntransactional mode is on/off, we templatize interfaces of mirror::Object and\nmirror::Array, respectively responsible for setting a field and setting an\narray element.\n\nFor various reasons, we skip some specific fields from transaction:\n- Object\u0027s class and array\u0027s length must remain unchanged so garbage collector\ncan compute object\u0027s size.\n- Immutable fields only set during class loading: list of fields, method,\ndex caches, vtables, ... as all classes have been loaded and verified before a\ntransaction occurs.\n- Object\u0027s monitor for performance reason.\n\nBefore generating the image, we browse the heap to collect objects that need to\nbe written into it. Since the heap may still holds references to unreachable\nobjects due to aborted transactions, we trigger one collection at the end of\nthe class preinitialization phase.\n\nSince the transaction is held by the runtime and all compilation threads share\nthe same runtime, we need to ensure only one compilation thread has exclusive\naccess to the runtime. To workaround this issue, we force class initialization\nphase to run with only one thread. Note this is only done when generating image\nso application compilation is not impacted. This issue will be addressed in a\nseparate CL.\n\nBug: 9676614\nChange-Id: I221910a9183a5ba6c2b99a277f5a5a68bc69b5f9\n" }, { "commit": "f5b0e20b5b31f5f5465784adcf2a204dcd69c7fd", "tree": "9e1b211414c1dcb34f19a7b509e72aee2153a3cf", "parents": [ "68bb649b128cd8760732524bd7ba58b49780d9d3" ], "author": { "name": "Hiroshi Yamauchi", "email": "yamauchi@google.com", "time": "Tue Feb 11 17:02:22 2014 -0800" }, "committer": { "name": "Hiroshi Yamauchi", "email": "yamauchi@google.com", "time": "Thu Feb 13 13:43:43 2014 -0800" }, "message": "Thread-local allocation stack.\n\nWith this change, Ritz MemAllocTest gets ~14% faster on N4.\n\nBug: 9986565\nChange-Id: I2fb7d6f7c5daa63dd4fc73ba739e6ae4ed820617\n" }, { "commit": "2300790c868f70862f1d1c2578a07c8d0f29d53d", "tree": "c7f45cdd8bc190f1679a9f84eef8593d49d42d88", "parents": [ "b422d3fed381d93451ffcf96cbf928d7a13d3701", "89bb1449bbef1863b12dfa3813ab7c78be94316f" ], "author": { "name": "Mathieu Chartier", "email": "mathieuc@google.com", "time": "Wed Feb 12 18:42:12 2014 +0000" }, "committer": { "name": "Gerrit Code Review", "email": "noreply-gerritcodereview@google.com", "time": "Wed Feb 12 18:42:13 2014 +0000" }, "message": "Merge \"Fix wrong thread id being passed to SIRT roots.\"" }, { "commit": "89bb1449bbef1863b12dfa3813ab7c78be94316f", "tree": "57e4d0325144cd01d73af8b2fe475b9f72b6bad0", "parents": [ "3c976a8f82007285316dd9d1bbccb659b0668a06" ], "author": { "name": "Mathieu Chartier", "email": "mathieuc@google.com", "time": "Wed Feb 12 10:06:23 2014 -0800" }, "committer": { "name": "Mathieu Chartier", "email": "mathieuc@google.com", "time": "Wed Feb 12 10:18:24 2014 -0800" }, "message": "Fix wrong thread id being passed to SIRT roots.\n\nFixes jhat on hprof dumps.\n\nChange-Id: I1a71eb3370606129fb5cf791ab582f34052a9f35\n" }, { "commit": "fd14755c09ada4769b5b6658e484441ca3f628b5", "tree": "c70c10b6e319f44dadb56c78acaf7ce89b502d82", "parents": [ "3c976a8f82007285316dd9d1bbccb659b0668a06", "0177e53ea521ad58b70c305700dab32f1ac773b7" ], "author": { "name": "Ian Rogers", "email": "irogers@google.com", "time": "Wed Feb 12 01:16:29 2014 +0000" }, "committer": { "name": "Gerrit Code Review", "email": "noreply-gerritcodereview@google.com", "time": "Wed Feb 12 01:16:30 2014 +0000" }, "message": "Merge \"Work in the direction of hard float quick ABIs.\"" }, { "commit": "0177e53ea521ad58b70c305700dab32f1ac773b7", "tree": "db15627a19a04634cf84cecd15b813319d80d225", "parents": [ "abaf927f29f6feceb3df3e6ced7d01970ba0dbe9" ], "author": { "name": "Ian Rogers", "email": "irogers@google.com", "time": "Tue Feb 11 16:30:46 2014 -0800" }, "committer": { "name": "Ian Rogers", "email": "irogers@google.com", "time": "Tue Feb 11 17:02:21 2014 -0800" }, "message": "Work in the direction of hard float quick ABIs.\n\nPass a shorty to ArtMethod::Invoke so that register setup can use it.\nDocument x86-64 ABI.\nAdd extra debug output for one JNI native method registration fails, namely a\ndump of the Class and its dex file\u0027s location.\nAdd hack to get testing of OatMethod\u0027s without GC maps working in 64bit.\n\nChange-Id: Ic06b68e18eac33637df2caf5e7e775ff95ae70f3\n" }, { "commit": "83c8ee000d525017ead8753fce6bc1020249b96a", "tree": "d5167ed15dee2629905ac3640b6ea0578d4ae312", "parents": [ "7cba217ab0661d74deccbb97160cdf60b74d4ea3" ], "author": { "name": "Mathieu Chartier", "email": "mathieuc@google.com", "time": "Tue Jan 28 14:50:23 2014 -0800" }, "committer": { "name": "Mathieu Chartier", "email": "mathieuc@google.com", "time": "Tue Feb 11 10:40:10 2014 -0800" }, "message": "Add root types and thread id to root visiting.\n\nEnables us to pass the root type and thread id to hprof.\n\nBug: 12680863\nChange-Id: I6a0f1f9e3aa8f9b4033d695818ae7ca3460d67cb\n" }, { "commit": "ef7d42fca18c16fbaf103822ad16f23246e2905d", "tree": "c67eea52a349c2ea7f2c3bdda8e73933c05531a8", "parents": [ "822115a225185d2896607eb08d70ce5c7099adef" ], "author": { "name": "Ian Rogers", "email": "irogers@google.com", "time": "Mon Jan 06 12:55:46 2014 -0800" }, "committer": { "name": "Ian Rogers", "email": "irogers@google.com", "time": "Thu Feb 06 23:20:27 2014 -0800" }, "message": "Object model changes to support 64bit.\n\nModify mirror objects so that references between them use an ObjectReference\nvalue type rather than an Object* so that functionality to compress larger\nreferences can be captured in the ObjectRefererence implementation.\nObjectReferences are 32bit and all other aspects of object layout remain as\nthey are currently.\n\nExpand fields in objects holding pointers so they can hold 64bit pointers.
