Force set resolved method for static invokes For static invokes, we may dispatch to the static method in the superclass but resolve using the subclass. To prevent getting slow paths on each invoke, we force set the resolved method for the super class dex method index if we are in the same dex file. Added test.

Support proxy method in StackVisitor::GetThisObject Adds function artQuickGetProxyThisObject which returns the 'this' object of the proxy method using the QuickArgumentVisitor. Since proxy methods have the same layout than the kRefsAndArgs runtime method and 'this' is the 1st method argument, it is located in the first GPR.

Change 64 bit ArtMethod fields to be pointer sized Changed the 64 bit entrypoint and gc map fields in ArtMethod to be pointer sized. This saves a large amount of memory on 32 bit systems. Reduces ArtMethod size by 16 bytes on 32 bit. Total number of ArtMethod on low memory mako: 169957 Image size: 49203 methods -> 787248 image size reduction. Zygote space size: 1070 methods -> 17120 size reduction. App methods: ~120k -> 2 MB savings. Savings per app on low memory mako: 125K+ per app (less active apps -> more image methods per app). Savings depend on how often the shared methods are on dirty pages vs shared. TODO in another CL, delete gc map field from ArtMethod since we should be able to get it from the Oat method header.

AArch64: Clean up CalleeSaveMethod frame and the use of temp registers. CalleeSaveMethod frame size changes : SaveAll : 368 -> 176 RefOnly : 176 -> 96 RefsAndArgs : 304 -> 224 JNI register spill size changes : 160 -> 88 In the transition assembly, use registers following the rules: 1. x0-x7 as temp/argument registers. 2. IP0, IP1 as scratch registers. 3. After correct type of callee-save-frame has been setup, all registers are scratch-able(probably except xSELF and xSUSPEND). 4. When restore callee-save-frame, IP0 and IP1 should be untouched. 5. From C to managed code, we assume all callee save register in AAPCS will be restored by managed code except x19(SUSPEND). In quick compiler: 1. Use IP0, IP1 as scratch register. 2. Use IP1 as hidden argument register(IP0 will be scratched by trampoline.) Change-Id: I05ed9d418b01b9e87218a7608536f57e7a286e4c

ART: Use StackReference in Quick Stack Frame The method reference at the bottom of a quick frame is a stack reference and not a native pointer. This is important for 64b architectures, where the notions do not coincide. Change key methods to have StackReference<mirror::ArtMethod>* parameter instead of mirror::ArtMethod**. Make changes to invoke stubs for 64b archs, change the frame setup for JNI code (both generic JNI and compilers), tie up loose ends. Tested on x86 and x86-64 with host tests. On x86-64, tests succeed with jni compiler activated. x86-64 QCG was not tested. Tested on ARM32 with device tests. Fix ARM64 not saving x19 (used for wSUSPEND) on upcalls. Tested on ARM64 in interpreter-only + generic-jni mode. Fix ARM64 JNI Compiler to work with the CL. Tested on ARM64 in interpreter-only + jni compiler.

Restore the args in the invoke trampoline slow paths. 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

Fixes for Generic JNI This fixes some linking issues and native code retrieval errors. All host tests are functional with this change. Make ArtMethod::GetFrameSizeInBytes() templated to bypass the embedded sanity check. Necessary for fix-up decision. Add ArtMethod metadata fix-up code to ClassLinker::LinkCode. Necessitates new parameters to access the shorty and compute the frame size. Fix handling the JNI dlsym lookup stub in the generic JNI code. Change-Id: I4173b0fbb1ba5b1bcbee1bb340cfdd08a54767e5

Fixing structure of native frame for Generic JNI This changes the layout of the callee-save frame used in generic JNI to be consistent with the JNI compiler, that is, the SIRT is inline (above the method reference). Now the location of the "this" object is consistent. Change-Id: Ibad0882680712cb640b4c70ada0229ef7cf4e62c

Remove blacklist 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. 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

Enable moving classes. Slight reduction in Zygote size, memory savings are in the noise. Before: Zygote size: 8739224 After: Zygote size: 8733568 Fixed a bug where we didn't set the concurrent start bytes after switching the allocator from bump pointer to ROSAlloc in the zygote. This caused excessive memory usage. Added the method verifiers as roots to fix an issue caused by RegTypes holding a Class*. Added logic to clear card table in the SemiSpace collector, this reduces DalvikOther from ~2400k -> ~1760k when using the SemiSpace collector. Added a missing lock to the timing loggers which caused a rare one time crash in std::set. Bug: 11771255 Bug: 8499494 Bug: 10802951 Change-Id: I99d2b528cd51c1c5ed7012e3220b3aefded680ae

Compacting collector. 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.. TODO: Enable switching allocators, compacting on background, etc.. Bug: 8981901 Change-Id: I3c886fd322a6eef2b99388d19a765042ec26ab99

Entry point clean up. Create set of entry points needed for image methods to avoid fix-up at load time: - interpreter - bridge to interpreter, bridge to compiled code - jni - dlsym lookup - quick - resolution and bridge to interpreter - portable - resolution and bridge to interpreter Fix JNI work around to use JNI work around argument rewriting code that'd been accidentally disabled. Remove abstact method error stub, use interpreter bridge instead. Consolidate trampoline (previously stub) generation in generic helper. Simplify trampolines to jump directly into assembly code, keeps stack crawlable. Dex: replace use of int with ThreadOffset for values that are thread offsets. Tidy entry point routines between interpreter, jni, quick and portable. Change-Id: I52a7c2bbb1b7e0ff8a3c3100b774212309d0828e (cherry picked from commit 848871b4d8481229c32e0d048a9856e5a9a17ef9)
