* | Refactor exception handling for deoptimizationSebastien Hertz2014-04-251-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | This CL refactors the exception handling (on the quick side) by isolating the search of catch handler and the preparation of deoptimization. We rename the CatchFinder class to QuickExceptionHandler so it's less specific to catch handler search. Finding catch handler happens in QuickExceptionHandler::FindCatch. Since the CatchBlockStackVisitor resolves exception types, it may cause thread suspension and breaks the assertion current thread can't be suspended. Therefore, we place the exception in a SirtRef (while it is detached from the current thread) and remove the thread suspension assertion. Deoptimization now happens in QuickExceptionHandler::DeoptimizeStack. It uses the new DeoptimizeStackVisitor class to create shadow frames. We also add the Thread::GetDeoptimizationException method to get the definition of the fake exception in only one place. Change-Id: I01b19fa72af64329b5c3b6c7f0c3339d2d724978

* ART: A workaround for a wrongly-read caller's frameVladimir Kostyukov2014-04-071-75/+32
| | | | | | | | | | | | The quick-trampoline treats caller's frame in a different way then it was formed by quck-invoke stub for hard float ABI targets such as x86_64 and aarch64. The patch workarounds the issue of wrongly-read stack arguments due to no contract between quick-invoke stub and quick-trampoline/shadow-frame-builder regarding the reg- spill area.

* Restore the args in the invoke trampoline slow paths.Mathieu Chartier2014-04-032-248/+229
| | | | | | | | | | | | | | | | | | Previously, there were errors caused by not restoring the args for the slow path in artInvokeInterfaceTrampoline and artInvokeCommon. The slow path in artInvokeInterfaceTrampoline occurs when you attempt to do an interface dispatch of a method in another dex file. The slow path in artInvokeCommon occurs when the method in dex cache is not already resolved. Since FindMethodFromCode may resolve a method, it can occasionally cause thread suspension/GC. If a moving GC occurred at this point it resulted in this_object being invalid after the trampoline returned the code pointer. This caused a native crash in one of the money runs since there was an unbundeled app which did a List.iterator call. Bug: 12934910 Change-Id: Ib454faad14bef0d7732a6d7f1ca5803472d502a6

* Remove blacklistSebastien Hertz2014-02-172-14/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Removes the class initialization blacklist and use transaction to detect and revert class initialization attempting to invoke native method. This only concerns class initialization happening at compilation time when generating an image (like boot.art for the system). In transactional mode, we log every object's field assignment and array update. Therefore we're able to abort a transaction to restore values of fields and array as they were before the transaction starts. We also log changes to the intern string table so we can restore its state prior to transaction start. Since transactional mode only happens at compilation time, we don't need to log all these changes at runtime. In order to reduce the overhead of testing if transactional mode is on/off, we templatize interfaces of mirror::Object and mirror::Array, respectively responsible for setting a field and setting an array element. For various reasons, we skip some specific fields from transaction: - Object's class and array's length must remain unchanged so garbage collector can compute object's size. - Immutable fields only set during class loading: list of fields, method, dex caches, vtables, ... as all classes have been loaded and verified before a transaction occurs. - Object's monitor for performance reason. Before generating the image, we browse the heap to collect objects that need to be written into it. Since the heap may still holds references to unreachable objects due to aborted transactions, we trigger one collection at the end of the class preinitialization phase. Since the transaction is held by the runtime and all compilation threads share the same runtime, we need to ensure only one compilation thread has exclusive access to the runtime. To workaround this issue, we force class initialization phase to run with only one thread. Note this is only done when generating image so application compilation is not impacted. This issue will be addressed in a separate CL. Bug: 9676614 Change-Id: I221910a9183a5ba6c2b99a277f5a5a68bc69b5f9

* Object model changes to support 64bit.Ian Rogers2014-02-066-38/+47
| | | | | | | | | | | | | | | | | | | | | | | Modify mirror objects so that references between them use an ObjectReference value type rather than an Object* so that functionality to compress larger references can be captured in the ObjectRefererence implementation. ObjectReferences are 32bit and all other aspects of object layout remain as they are currently. Expand fields in objects holding pointers so they can hold 64bit pointers. Its expected the size of these will come down by improving where we hold compiler meta-data. Stub out x86_64 architecture specific runtime implementation. Modify OutputStream so that reads and writes are of unsigned quantities. Make the use of portable or quick code more explicit. Templatize AtomicInteger to support more than just int32_t as a type. Add missing, and fix issues relating to, missing annotalysis information on the mutator lock. Refactor and share implementations for array copy between System and uses elsewhere in the runtime. Fix numerous 64bit build issues. Change-Id: I1a5694c251a42c9eff71084dfdd4b51fff716822

When we transition back to foreground, we copy back to a free-list backed space. Create a seperate non-moving space which only holds non-movable objects. This enables us to quickly wipe the current alloc space (DlMalloc / RosAlloc) when we transition to background. Added multiple alloc space support to the sticky mark sweep GC.

* Thread local bump pointer allocator.Mathieu Chartier2013-12-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Added a thread local allocator to the heap, each thread has three pointers which specify the thread local buffer: start, cur, and end. When the remaining space in the thread local buffer isn't large enough for the allocation, the allocator allocates a new thread local buffer using the bump pointer allocator. The bump pointer space had to be modified to accomodate thread local buffers. These buffers are called "blocks", where a block is a buffer which contains a set of adjacent objects. Blocks aren't necessarily full and may have wasted memory towards the end. Blocks have an 8 byte header which specifies their size and is required for traversing bump pointer spaces. Memory usage is in between full bump pointer and ROSAlloc since madvised memory limits wasted ram to an average of 1/2 page per block. Added a runtime option -XX:UseTLAB which specifies whether or not to use the thread local allocator. Its a NOP if the garbage collector is not the semispace collector. TODO: Smarter block accounting to prevent us reading objects until we either hit the end of the block or GetClass() == null which signifies that the block isn't 100% full.

* Compacting collector.Mathieu Chartier2013-11-112-8/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The compacting collector is currently similar to semispace. It works by copying objects back and forth between two bump pointer spaces. There are types of objects which are "non-movable" due to current runtime limitations. These are Classes, Methods, and Fields. Bump pointer spaces are a new type of continuous alloc space which have no lock in the allocation code path. When you allocate from these it uses atomic operations to increase an index. Traversing the objects in the bump pointer space relies on Object::SizeOf matching the allocated size exactly. Runtime changes: JNI::GetArrayElements returns copies objects if you attempt to get the backing data of a movable array. For GetArrayElementsCritical, we return direct backing storage for any types of arrays, but temporarily disable the GC until the critical region is completed. Added a new runtime call called VisitObjects, this is used in place of the old pattern which was flushing the allocation stack and walking the bitmaps. Changed image writer to be compaction safe and use object monitor word for forwarding addresses. Added a bunch of added SIRTs to ClassLinker, MethodLinker, etc..

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to profiling results, field and method resolutions are hot points during interpreter execution. This CL attempts to speed up these resolutions. Forces aggressive inlining of FindFieldFromCode and FindMethodFromCode. This allows to reduce the overhead of access check code when the interpreter runs without these checks. Templatize these functions to optimize inlining and their callers. Also spread the use of C++11 "nullptr" in place of "NULL" in field access and invoke helpers. Change-Id: Ic1a69834d8975b2cddcddaae32f08a7de146a951
* | Populate dex cache for sharpened calls.Ian Rogers2013-10-251-0/+16
|/ | | | | | | | | | | We ensured the resolved method was in the dex cache, but for a sharpened call this is abstract. Ensure that the concrete method is also resolved. Limit the use of direct dex cache based dispatch to cases where we know how to patch the dex cache. Bug 11389002 Change-Id: I08252686a53b5948650632837c74bcd5cbf8a862
* Fast JNI support.Ian Rogers2013-10-202-12/+31
| | | | | | | Use a modifier to signal a native method is a fast JNI method. If the modifier is set then don't perform runnable transitions. Change-Id: I7835b4d837bfdd1cb8e2d54b919c0d5e6cf90499
* Improve quick codegen for aput-object.Ian Rogers2013-10-084-44/+27
| | | | | | | | | | | | | | | 1) don't type check known null. 2) if we know types in verify don't check at runtime. 3) if we're runtime checking then move all the code out-of-line. Also, don't set up a callee-save frame for check-cast, do an instance-of test then throw an exception if that fails. Tidy quick entry point of Ldivmod to Lmod which it is on x86 and mips. Fix monitor-enter/exit NPE for MIPS. Fix benign bug in mirror::Class::CannotBeAssignedFromOtherTypes, a byte[] cannot be assigned to from other types.
