* ART: Add missing GetInterfaceMethodIfProxyAndreas Gampe2015-10-121-4/+4
| | | | | | | | | | | | | Add missing uses of GetInterfaceMethodIfProxy in reflection code. Add a test case for a JNI call to a proxy method. Bug: https://code.google.com/p/android-developer-preview/issues/detail?id=2973 Bug: 23886441 (cherry picked from commit e80673245c0433a71a4930e460be5dc0920885b2) Change-Id: I5b66b64b5561fcee15d0314707d67e8abc02ce5b

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: 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.

* Fix updating of JNI references for String.<init>.Jeff Hao2015-05-271-4/+21
| | | | | | | | Was missing updates to globals and weak globals. Bug: 21288130 Bug: 21440428 Change-Id: I5f801f68b61f6b066b441b92ace367e6ba434789
* Intercept JNI invocation of String.<init> methods.Jeff Hao2015-05-201-3/+44
| | | | | | | | | | | 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

* Add AccessibleObject and Field to mirrorMathieu Chartier2015-03-291-16/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Main motivation is to remove all the functionality / field access on java side to ArtField. Also comes with some reflection speedups / slowdowns. Summary results: getDeclaredField/getField are slower mostly due to JNI overhead. However, there is a large speedup in getInt, setInt, GetInstanceField, and GetStaticField.

* 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%.

| * Reduce stack usage for overflow checksDave Allison2014-08-131-0/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reduces the stack space reserved for overflow checks to 12K, split into an 8K gap and a 4K protected region. GC needs over 8K when running in a stack overflow situation. Also prevents signal runaway by detecting a signal inside code that resulted from a signal handler invokation. And adds a max signal count to the SignalTest to prevent it running forever. Also reduces the number of iterations for the InterfaceTest as this was taking (almost) forever with the --trace option on run-test. Bug: 15435566 Change-Id: Id4fd46f22d52d42a9eb431ca07948673e8fda694
* | Avoid use of std::string where we have const char*.Ian Rogers2014-08-121-7/+8
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | Removing the ClassHelper caused std::string creation for all calls to Class::GetDescriptor and a significant performance regression. Make the std::string an out argument so the caller can maintain it and its life time while allowing GetDescriptor to return the common const char* case. Don't generate GC maps when compilation is disabled. Remove other uses of std::string that are occuring on critical paths. Use the cheaper SkipClass in CompileMethod in CompilerDriver. Specialize the utf8 as utf16 comparison code for the common shorter byte encoding. Force a bit of inlining, remove some UNLIKELYs (they are prone to pessimizing code), add some LIKELYs. x86-64 host 1-thread interpret-only of 57 apks: Before: 29.539s After: 23.467s Regular compile: Before: 1m35.347s After: 1m20.056s Bug: 16853450 Change-Id: Ic705ea24784bee24ab80084d06174cbf87d557ad

| | | | | | | | | | Pass a shorty to ArtMethod::Invoke so that register setup can use it. Document x86-64 ABI. Add extra debug output for one JNI native method registration fails, namely a dump of the Class and its dex file's location. Add hack to get testing of OatMethod's without GC maps working in 64bit.

* Enable moving classes.Mathieu Chartier2013-12-101-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | 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
