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 and improve GC root handlingMathieu Chartier2015-04-061-4/+8
| | | | | | | | | | | | | | | | | | | | | | Changed GcRoot to use compressed references. Changed root visiting to use virtual functions instead of function pointers. Changed root visting interface to be an array of roots instead of a single root at a time. Added buffered root marking helper to avoid dispatch overhead. Root marking seems a bit faster on EvaluateAndApplyChanges due to batch marking. Pause times unaffected. Mips64 is untested but might work, maybe.

* Add AccessibleObject and Field to mirrorMathieu Chartier2015-03-291-3/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* ART: PathClassLoader for compilerAndreas Gampe2015-03-271-2/+15
| | | | | | | | | | | | | | | | | | | | 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

* Print more info in MarkSweep::VerifyRootMathieu Chartier2015-01-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Refactored old root callback to use a new class called RootInfo. RootInfo contains all the relevant info related to the root associated with the callback. The MarkSweep::VerifyRoot function now uses this info to print the StackVisitor's described location if the GC root is of the type kRootJavaFrame. Some other cleanup. Example output: E/art (12167): Tried to mark 0x123 not contained by any spaces E/art (12167): Attempting see if it's a bad root E/art (12167): Found invalid root: 0x123 with type RootJavaFrame E/art (12167): Location=Visiting method 'void java.lang.Runtime.gc()' at dex PC 0xffffffff (native PC 0x0) vreg=0 (cherry picked from commit 12f7423a2bb4bfab76700d84eb6d4338d211983a) Bug: 18588862 Change-Id: Ic5a2781f704e931265ffb3621c2eab4b2e25f60f

| * JDWP: fix breakpoint for method in the imageSebastien Hertz2014-12-041-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we set a breakpoint in a compiled method, we deoptimize it by changing its entrypoint so it is executed with the interpreter. However, methods in the image can be called with their direct code pointer, ignoring the updated entrypoint. In that case, the method is not executed with the interpreter and we miss the breakpoint. This CL avoids that situation by forcing a full deoptimization so everything runs with the interpreter. However, if the image has been compiled in PIC mode, we keep using selective deoptimization because direct code pointer is not used in this mode.

* Change 64 bit ArtMethod fields to be pointer sizedMathieu Chartier2014-11-181-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | Changed the 64 bit entrypoint and gc map fields in ArtMethod to be pointer sized. This saves a large amount of memory on 32 bit systems. Reduces ArtMethod size by 16 bytes on 32 bit. Total number of ArtMethod on low memory mako: 169957 Image size: 49203 methods -> 787248 image size reduction. Zygote space size: 1070 methods -> 17120 size reduction. App methods: ~120k -> 2 MB savings. Savings per app on low memory mako: 125K+ per app (less active apps -> more image methods per app). Savings depend on how often the shared methods are on dirty pages vs shared. TODO in another CL, delete gc map field from ArtMethod since we should be able to get it from the Oat method header.

| | | | | | | | | | | | | The fields of a class are ordered alphabetically in the dex file. Keep the same order in the field arrays so that we can do binary search lookups by name.

* Fix 2 new sets of clang compiler warnings.Ian Rogers2014-10-101-4/+4
| | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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%.

* Remove reference_static_offsets used for iterating through class static fields.Mingyao Yang2014-09-101-1/+0
| | | | | | | | | | | | Since static fields are contiguous in class object and there is no need to traverse super classes, it's not meaningful to use reference_static_offsets. Also especially with embedded vtable/imt, static field offset can't be encoded with an unsigned integer anyway. A corresponding change is made to Class.java to remove the member field.

* Avoid use of std::string where we have const char*.Ian Rogers2014-08-121-15/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | This reverts commit e09ae0920be57760fb390b6944bce420fa0b5582. Change-Id: I48036306130d5ccfec683d0dc3e9a642a02ee9c1
* 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.

* Now we have a proper C++ library, use std::unique_ptr.Ian Rogers2014-05-191-1/+1
| | | | | | | Also remove the Android.libcxx.mk and other bits of stlport compatibility mechanics. Change-Id: Icdf7188ba3c79cdf5617672c1cfd0a68ae596a61
* Delete ClassHelper and fix compaction bug in GetDirectInterfaceMathieu Chartier2014-05-181-54/+56
| | | | | | | | | | | Cleanup helps to prevent compaction bugs. Fixed a fairly serious compaction error caused by calling ClassHelper::GetDirectInterface without handling the case where it causes thread suspension due to ResolveType. Bug: 8981901 Change-Id: I82b3bb6dd48d21eb6ece7aae0733c4a23c2bc408
* Compatibility layer to transition from UniquePtr to std::unique_ptr.Ian Rogers2014-05-151-1/+1
| | | | | | | | | 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 Chartier2014-05-131-69/+86
| | | | | | | | | | | | | | | | 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
* Move quick frame info to OatQuickMethodHeader.Vladimir Marko2014-05-131-3/+0
| | | | | | | | | | | | | | | Rename OatMethodHeader to OatQuickMethodHeader, move frame info from OatMethodOffsets to OatQuickMethodHeader. Retrieve the info from other places for non-quick methods (portable compiled bytecode or jni stub, generic jni, runtime, abstract and proxy). This change has a libcore/ companion CL "Remove ArtMethod's quick fields for frame size and spills." https://android-review.googlesource.com/94164 Bug: 11767815 Change-Id: I0e31a7875d76732e1ec479c86b9b5ca01203507f
* Move mapping table and vmap table offsets to OatMethodHeader.Vladimir Marko2014-04-251-2/+0
| | | | | | | | | This change has a libcore/ companion CL "Remove ArtMethod's quick fields mapping table and vmap table." https://android-review.googlesource.com/91254 Bug: 11767815 Change-Id: I46ce2067e1ecd915da3890606498e31ffc332813
* Make the support code for read barriers a bit more general.Hiroshi Yamauchi2014-03-311-7/+7
| | | | | | | Add an option for Baker in addition to Brooks. Bug: 12687968 Change-Id: I8a31db817ff6686c72951b6534f588228e270b11
* Refactor reference code into mirror namespace.Mathieu Chartier2014-03-141-0/+22
| | | | | | Added two new files: mirror/reference.h and mirror/reference-inl.h. Change-Id: Ibe3ff6379aef7096ff130594535b7f7c0b7dabce
