* Remove ThrowLocation.Nicolas Geoffray2015-03-101-6/+2
| | | | | | | Note that this is a cleanup change, and has no functionality change. The ThrowLocation had no use anymore. Change-Id: I3d2126af1dc673cec3a0453ff3d56a172663a5f6
* Refactor quick entrypointsIan Rogers2014-10-201-8/+6
| | | | | | | | | | | Remove FinishCalleeSaveFrameSetup. Assembly routines write down anchor into TLS as well as placing runtime method in callee save frame. Simplify artSet64InstanceFromCode by not computing the referrer from the stack in the C++ code. Move assembly offset tests next to constant declaration and tidy arch_test.

* ART: Use StackReference in Quick Stack FrameAndreas Gampe2014-05-291-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Enable annotalysis on clang ART builds.Ian Rogers2014-03-061-2/+4
| | | | | | | | | | | Fix clang build errors aswell as restructure locking/mutex code for correct thread safety analysis support. Reorder make dependencies so that host builds build first as they should provide better compilation errors than target. Remove host's use of -fno-omit-frame-pointer as it has no value with correct use of CFI, which we should have. Change-Id: I72cea8da9a3757b1a0b3acb4081feccb7c6cef90
* Remove using mirror::* in jni internal.Mathieu Chartier2014-02-141-4/+2
| | | | | | | | | Cleans up the code since it helps make it easier to spot moving GC related bugs. Also fixed moving GC bugs in MonitorEnter, and FindFieldID. Change-Id: I794e4fbcc2010875fc6b299c6d4c9fb0f071b71a
* Compacting collector.Mathieu Chartier2013-11-111-3/+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
* Inflate contended lock word by suspending owner.Ian Rogers2013-10-021-15/+27
| | | | | | | | | | | | | | | | | | | | Bug 6961405. Don't inflate monitors for Notify and NotifyAll. Tidy lock word, handle recursive lock case alongside unlocked case and move assembly out of line (except for ARM quick). Also handle null in out-of-line assembly as the test is quick and the enter/exit code is already a safepoint. To gain ownership of a monitor on behalf of another thread, monitor contenders must not hold the monitor_lock_, so they wait on a condition variable. Reduce size of per mutex contention log. Be consistent in calling thin lock thread ids just thread ids. Fix potential thread death races caused by the use of FindThreadByThreadId, make it invariant that returned threads are either self or suspended now. Code size reduction on ARM boot.oat 0.2%. Old nexus 7 speedup 0.25%, new nexus 7 speedup 1.4%, nexus 10 speedup 2.24%, nexus 4 speedup 2.09% on DeltaBlue. Change-Id: Id52558b914f160d9c8578fdd7fc8199a9598576a
* Refactor java.lang.reflect implementationBrian Carlstrom2013-08-131-2/+2
| | | | | | | | | | | Cherry-picked from commit ed41d5c44299ec5d44b8514f6e17f802f48094d1. Move to ArtMethod/Field instead of AbstractMethod/Field and have java.lang.reflect APIs delegate to ArtMethod/ArtField. Bug: 10014286. Change-Id: Iafc1d8c5b62562c9af8fb9fd8c5e1d61270536e7
* Move assembler out of runtime into compiler/utils.Ian Rogers2013-07-291-0/+42
Other directory layout bits of clean up. There is still work to separate quick and portable in some files (e.g. argument visitor, proxy..). Change-Id: If8fecffda8ba5c4c47a035f0c622c538c6b58351
