* Move mirror::ArtMethod to nativeMathieu Chartier2015-06-021-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Optimizing + quick tests are passing, devices boot. TODO: Test and fix bugs in mips64. Saves 16 bytes per most ArtMethod, 7.5MB reduction in system PSS. Some of the savings are from removal of virtual methods and direct methods object arrays. Bug: 19264997 (cherry picked from commit e401d146407d61eeb99f8d6176b2ac13c4df1e33) Change-Id: I622469a0cfa0e7082a2119f3d6a9491eb61e3f3d Fix some ArtMethod related bugs Added root visiting for runtime methods, not currently required since the GcRoots in these methods are null. Added missing GetInterfaceMethodIfProxy in GetMethodLine, fixes --trace run-tests 005, 044. Fixed optimizing compiler bug where we used a normal stack location instead of double on ARM64, this fixes the debuggable tests. TODO: Fix JDWP tests. Bug: 19264997 Change-Id: I7c55f69c61d1b45351fd0dc7185ffe5efad82bd3 ART: Fix casts for 64-bit pointers on 32-bit compiler. Bug: 19264997 Change-Id: Ief45cdd4bae5a43fc8bfdfa7cf744e2c57529457 Fix JDWP tests after ArtMethod change Fixes Throwable::GetStackDepth for exception event detection after internal stack trace representation change. Adds missing ArtMethod::GetInterfaceMethodIfProxy call in case of proxy method. Bug: 19264997 Change-Id: I363e293796848c3ec491c963813f62d868da44d2 Fix accidental IMT and root marking regression Was always using the conflict trampoline. Also included fix for regression in GC time caused by extra roots. Most of the regression was IMT. Fixed bug in DumpGcPerformanceInfo where we would get SIGABRT due to detached thread. EvaluateAndApplyChanges: From ~2500 -> ~1980 GC time: 8.2s -> 7.2s due to 1s less of MarkConcurrentRoots Bug: 19264997 Change-Id: I4333e80a8268c2ed1284f87f25b9f113d4f2c7e0 Fix bogus image test assert Previously we were comparing the size of the non moving space to size of the image file. Now we properly compare the size of the image space against the size of the image file. Bug: 19264997 Change-Id: I7359f1f73ae3df60c5147245935a24431c04808a [MIPS64] Fix art_quick_invoke_stub argument offsets. ArtMethod reference's size got bigger, so we need to move other args and leave enough space for ArtMethod* and 'this' pointer. This fixes mips64 boot.

| | | | | | | | | | | | | Refactor the RuntimeOptions to be a type-safe map (VariantMap, see runtime_options.h) and the ParsedOptions to delegate the parsing to CmdlineParser (see cmdline/cmdline_parser.h). This is the start of a command line parsing refactor, and may include more in the future (dex2oat, patchoat, etc).

* ARM: Use hardfp calling convention between java to java call.Zheng Xu2014-10-241-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch default to use hardfp calling convention. Softfp can be enabled by setting kArm32QuickCodeUseSoftFloat to true. We get about -1 ~ +5% performance improvement with different benchmark tests. Hopefully, we should be able to get more performance by address the left TODOs, as some part of the code takes the original assumption which is not optimal. DONE: 1. Interpreter to quick code 2. Quick code to interpreter 3. Transition assembly and callee-saves 4. Trampoline(generic jni, resolution, invoke with access check and etc.) 5. Pass fp arg reg following aapcs(gpr and stack do not follow aapcs) 6. Quick helper assembly routines to handle ABI differences 7. Quick code method entry 8. Quick code method invocation 9. JNI compiler TODO: 10. Rework ArgMap, FlushIn, GenDalvikArgs and affected common code. 11. Rework CallRuntimeHelperXXX(). Change-Id: I9965d8a007f4829f2560b63bcbbde271bdcf6ec2

* Add mark compact collector.Mathieu Chartier2014-06-191-1/+4
| | | | | | | | | | | | | | | | | | | | | | The mark compact collector is a 4 phase collection, doing a normal full mark_sweep, calculating forwarding addresses of objects in the from space, updating references of objects in the from space, and moving the objects in the from space. Support is diabled by default since it needs to have non movable classes and field arrays. Performance numbers is around 50% as fast. The main advantage that this has over semispace is that the worst case memory usage is 50% since we only need one space isntead of two. TODO: Make field arrays and classes movable. This causes complication since Object::VisitReferences relies on these, so if we update the fields of an object but another future object uses this object to figure out what fields are reference fields it doesn't work.

* ART: Generalize code to find PC for artInvokeInterfaceTrampolineAlexei Zavjalov2014-06-101-21/+0
| | | | | | | | | | | | | | | | This allows to determine target method when the interface method has no dex index, now also for X86-64 and ARM64. Add constexpr functions to callee_save_frame.h to have compile-time sizes of callee-save frames. Add a test that ensures they agree with computations by the corresponding ArtMethod methods. Move some instruction-set functions into the header file to allow inlining them. Move arch-specific pointer sizes and alignment sizes out of globals.h to instruction_set.h to reduce dependencies.

* AArch64: Change arm64 backend to produce A64 code.Matteo Franchin2014-05-071-3/+2
| | | | | | | | | | | | | | The arm backend clone is changed to produce A64 code. At the moment this backend can only compile simple methods (both leaf and non-leaf). Most of the work on the assembler (assembler_arm64.cc) has been done. Some work on the LIR generation layer (functions such as OpRegRegImm & friends) is still necessary. The register allocator still needs to be adapted to the A64 instruction set (it is mostly unchanged from the arm backend). Offsets for helpers in gen_invoke.cc still need to be changed to work on 64-bit. Change-Id: I388f99eeb832857981c7d9d5cb5b71af64a4b921

* Object model changes to support 64bit.Ian Rogers2014-02-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | 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
* Use direct class pointers at allocation sites in the compiled code.Hiroshi Yamauchi2014-01-231-0/+4
| | | | | | | | | | | | | | | | | | | | | | | - Rather than looking up a class from its type ID (and checking if it's resolved/initialized, resolving/initializing if not), use direct class pointers, if possible (boot-code-to-boot-class pointers and app-code-to-boot-class pointers.) - This results in a 1-2% speedup in Ritz MemAllocTest on Nexus 4. - Embedding the object size (along with class pointers) caused a 1-2% slowdown in MemAllocTest and isn't implemented in this change. - TODO: do the same for array allocations. - TODO: when/if an application gets its own image, implement app-code-to-app-class pointers. - Fix a -XX:gc bug. cf. https://android-review.googlesource.com/79460/ - Add /tmp/android-data/dalvik-cache to the list of locations to remove oat files in clean-oat-host. cf. https://android-review.googlesource.com/79550 - Add back a dropped UNLIKELY in FindMethodFromCode(). cf. https://android-review.googlesource.com/74205 Bug: 9986565 Change-Id: I590b96bd21f7a7472f88e36752e675547559a5b1
* Enable moving classes.Mathieu Chartier2013-12-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Compact zygote.Mathieu Chartier2013-11-221-22/+22
| | | | | | | | | | | | | | | | | | | | | We now start out using the bump pointer allocator and switch to the free list collector (ROSAlloc) after the zygote forks. Before compaction: Zygote size: 9060352 After compaction Zygote size: 8425864 The main reason the size doesn't reduce more is that most of the zygote space is non-movable objects allocated by VMRuntime.newNonMovableObject. The objects which are non-movable but could be movable include around 10000 classes and some number of fields and methods. Bug: 8981901 Change-Id: Iea21b70fb7af27cb7e92d72070d278a5cd4026ac

* Compacting collector.Mathieu Chartier2013-11-111-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

The runtime, compiler, dex2oat, and oatdump now are in seperate trees to prevent dependency creep. They can now be individually built without rebuilding the rest of the art projects. dalvikvm and jdwpspy were already this way. Builds in the art directory should behave as before, building everything including tests. Change-Id: Ic6b1151e5ed0f823c3dd301afd2b13eb2d8feb81
