* Add and use loaded class profilingMathieu Chartier2016-02-261-2/+2
| | | | | | | | | | | | | | Class profiling is a way to keep track of which classes are resolved. From here the compiler can use this information to generate a smaller app image. TODO: Add tests for profile stuff. Bug: 22858531 (cherry picked from commit 8913fc1a27df8cf3b37fd99e94d87f290591328e) Change-Id: Ifcd09230cbdc266305bc1247e0d31e7920eb353e

* x86/x86-64 read barrier support for concurrent GC in Optimizing.Roland Levillain2015-11-151-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | This first implementation uses slow paths to instrument heap reference loads and GC root loads for the concurrent copying collector, respectively calling the artReadBarrierSlow and artReadBarrierForRootSlow (new) runtime entry points. Notes: - This implementation does not instrument HInvokeVirtual nor HInvokeInterface instructions (for class reference loads), as the corresponding read barriers are not stricly required with the current concurrent copying collector. - Intrinsics which may eventually call (on slow path) are disabled when read barriers are enabled, as the current slow path infrastructure does not support this case. - When read barriers are enabled, the code generated for a HArraySet instruction always go into the array set slow path for object arrays (delegating the operation to the runtime), as we are lacking a mechanism to keep a temporary register live accross a runtime call (needed for the instrumentation of type checking code, which requires two successive read barriers).

| | | | | | | | | | | | This reverts commit 81a9087f0df0518c39405b7d18ba5858a6d8b77b. Boot.oat creation time goes from 4.7s to 4.9s on host due to extra locking. Will try to improve this in another CL. Bug: 23602225 Bug: 22720414 Change-Id: I7e25b75cfb63faa196c7b0f60e46cce50bf12021
* Fix some HandleScope bugs and add corresponding checksMathieu Chartier2015-08-281-1/+1
| | | | | | | | | | | Some places were creating or destroying handle scopes without holding the mutator lock. This can cause GC crashes if thread roots are being marked or hprof dumps to also fail. Also added checks to catch some of these errors. Bug: 23468617 Change-Id: I1a2d615923484cfc25014967656775c445aa3f1f

| | | | | | | | | | | | | 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 Change-Id: I622469a0cfa0e7082a2119f3d6a9491eb61e3f3d

* ART: PathClassLoader for compilerAndreas Gampe2015-03-271-3/+2
| | | | | | | | | | | | | | | | | | | | Use an actual PathClassLoader when compiling apps, instead of a side structure and cutout. This CL sets up a minimal object 'cluster' that recreates the Java side of a regular ClassLoader such that the Class-Linker will recognize it and use the internal native fast-path. This CL removes the now unnecessary compile-time-classpath and replaces it with a single 'compiling-the-boot-image' flag in the compiler callbacks. Note: This functionality is *only* intended for the compiler, as the objects have not been completely initialized. Bug: 19781184 Change-Id: I7f36af12dd7852d21281110a25c119e8c0669c1d

The new format has two types, a start timing and a stop timing. You can thing of these as brackets associated with a timestamp. It uses these to construct various statistics when needed, such as: Total time, exclusive time, and nesting depth. Changed PrettyDuration to have a default of 3 digits after the decimal point.

* Fix an outstanding compaction bug in interpreter.Mathieu Chartier2014-05-221-4/+3
| | | | | | | | | | | | | | | | Fixed a bug in DoFieldPut where the FieldHelper GetType could cause thread suspension which would result in a stale obj. Added more handles in the class linker to facilitate moving fiels and methods in the future. Removed un-necessarly passing handle references since these are value types and don't need to be passed by reference. Added a special NullHandle type which allows null handles without a handle scope.

| | | | | | | | | Use ART_WITH_STLPORT (enabled for the target) to cause the use of UniquePtr, for the host switch to std::unique_ptr. For now the type remains called UniquePtr. Make dalvik compile with clang on the host, move its build to C++11. Change-Id: I5ba8d2757904bc089ed62047ea03de3c0853fb12
* Add Handle/HandleScope and delete SirtRef.Mathieu Chartier2014-05-131-3/+6
| | | | | | | | | | | | | | | | Delete SirtRef and replaced it with Handle. Handles are value types which wrap around StackReference*. Renamed StackIndirectReferenceTable to HandleScope. Added a scoped handle wrapper which wraps around an Object** and restores it in its destructor. Renamed Handle::get -> Get. Bug: 8473721 Change-Id: Idbfebd4f35af629f0f43931b7c5184b334822c7a

* Avoid std::string allocations for finding an array class.Ian Rogers2014-02-241-3/+2
| | | | | | | | | | | | Introduce ClassLinker::FindArrayClass which performs an array class lookup given the element/component class. This has a 16 element cache of recently looked up arrays. Pass the current thread to ClassLinker Find .. Class routines to avoid calls to Thread::Current(). Avoid some uses of FindClass in the debugger where WellKnownClasses is a faster and more compacting GC friendly alternative. Change-Id: I60e231820b349543a7edb3ceb9cf1ce92db3c843
* Object model changes to support 64bit.Ian Rogers2014-02-061-1/+5
| | | | | | | | | | | | | | | | | | | | | | | 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
* Fix memory leaks relating to timing logger.Ian Rogers2013-11-141-1/+2
| | | | | | | | | Bug: 11670287. We use pointers to uninitialized values for control-flow in the timing logger code, add TODO comments to clean this up later. Remove base namespace and other bits of tidying. Change-Id: I1e6600a1e92f974c8f58f3a405a4e4abb4d9f80f
* Compacting collector.Mathieu Chartier2013-11-111-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* Create separate Android.mk for main build targetsBrian Carlstrom2013-07-121-0/+166
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
