* Move mirror::ArtMethod to nativeMathieu Chartier2015-06-021-17/+17

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.

* Intercept JNI invocation of String.<init> methods.Jeff Hao2015-05-201-46/+58
| | | | | | | | | | | libmono uses JNI AllocObject and CallNonvirtualVoidMethod to create and initialize a string instead of using the recommended NewObject. This change adds an intercept to change the String.<init> call to a StringFactory call instead. Then, it uses the object id of the original string object referrer and maps it to the result of the StringFactory. Bug: 21288130 Change-Id: Ib4db402c178bc37188d5c5faf30b6e4fdc747b17
* Replace NULL with nullptrMathieu Chartier2015-04-221-13/+13
| | | | | | | Also fixed some lines that were too long, and a few other minor details. Change-Id: I6efba5fb6e03eb5d0a300fddb2a75bf8e2f175cb

* ART: More warningsAndreas Gampe2014-11-041-2/+2
| | | | | | | Enable -Wno-conversion-null, -Wredundant-decls and -Wshadow in general, and -Wunused-but-set-parameter for GCC builds. Change-Id: I81bbdd762213444673c65d85edae594a523836e5
* Fix 2 new sets of clang compiler warnings.Ian Rogers2014-10-101-18/+18
| | | | | | | | | | | Fix issues that are flagged by -Wfloat-equal and -Wmissing-noreturn. In the case of -Wfloat-equal the current cases in regular code are deliberate, so the change is to silence the warning. For gtest code the appropriate fix is to switch from EXPECT_EQ to EXPECT_(FLOAT|DOUBLE)_EQ. The -Wmissing-noreturn warning isn't enabled due to a missing noreturn in gtest. This issue has been reported to gtest. Change-Id: Id84c70c21c542716c9ee0c41492e8ff8788c4ef8
* Compile time performance improvements focusing on interpret-only.Ian Rogers2014-09-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reduce virtual method dispatch in the method verifier and make more code inline-able. Add a StringPiece with const char* equality operator to avoid redundant StringPieces and strlens. Remove back link from register line to verifier and pass as argument to reduce size of RegisterLine. Remove instruction length from instruction flags and compute from the instruction, again to reduce size. Add suspend checks to resolve and verify to allow for more easy monitor inflation and reduce contention on Locks::thread_list_suspend_thread_lock_. Change ThrowEarlierClassFailure to throw pre-allocated exception. Avoid calls to Thread::Current() by passing self. Template specialize IsValidClassName. Make ANR reporting with SIGQUIT run using checkpoints rather than suspending all threads. This makes the stack/lock analysis less lock error prone. Extra Barrier assertions and condition variable time out is now returned as a boolean both from Barrier and ConditionVariable::Wait. 2 threaded host x86-64 interpret-only numbers from 341 samples: Before change: Avg 176.137ms 99% CI 3.468ms to 1060.770ms After change: Avg 139.163% 99% CI 3.027ms to 838.257ms Reduction in average compile time after change is 20.9%. Slow-down without change is 26.5%. Bug: 17471626 - Fix bug where RegTypeCache::JavaLangObject/String/Class/Throwable could return unresolved type when class loading is disabled. Bug: 17398101 Change-Id: Id59ce3cc520701c6ecf612f7152498107bc40684
* Break apart header files.Ian Rogers2014-07-151-0/+2
| | | | | | | | Create libart-gtest for common runtime and compiler gtest routines. Rename CompilerCallbacksImpl that is quick compiler specific. Rename trace clock source constants to not use the overloaded profiler term. Change-Id: I4aac4bdc7e7850c68335f81e59a390133b54e933
* Add missing class initialization during compilation and testsSebastien Hertz2014-07-101-1/+10
| | | | | | | | | | | | | | | | | Adds missing class initialization during compilation and tests, especially java.lang.Class. Otherwise, we'd be able to execute code while the referring class is not initialized or initializing. Also adds mirror::Class::AssertInitializedOrInitializingInThread method to check class initialization when entering the interpreter: the called method's declaring class must either be initialized or be initializing by the current thread (other threads must be waiting for the class initialization to complete holding its lock). Note we only do this check in debug build. Bump oat version to force compilation. Bug: 15899971 Change-Id: I9a4edd3739a3ca4cf1c4929dcbb44cdf7a1ca1fe
* Add Handle/HandleScope and delete SirtRef.Mathieu Chartier2014-05-131-6/+7
| | | | | | | | | | | | | | | | 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

* Refactor reflective method invocation.Ian Rogers2014-03-141-0/+627
Move invocation code out of JNI internal into reflection, including ArgArray code. Make reflective invocation use the ArgArray to build arguments rather than allocating a jvalue[] and unboxing arguments into that. Move reflection part of jni_internal_test into reflection_test. Make greater use of fast JNI. Change-Id: Ib381372df5f9a83679e30e7275de24fa0e6b1057
