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.

| | | | | | | | | | | Add intrinsics implementations for indexOf in the optimizing compiler. These are mostly ported from Quick. Bug: 20889065 (cherry picked from commit ba6fdbcb764d5a8972f5ff2d7147e4d78226b347) Change-Id: I18ee849d41187a381f99529669e6f97040aaacf6

| * Have HInvoke instructions know their number of actual arguments.Roland Levillain2015-04-281-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add an art::HInvoke::GetNumberOfArguments routine so that art::HInvoke and its subclasses can return the number of actual arguments of the called method. Use it in code generators and intrinsics handlers. Consequently, no longer remove a clinit check as last input of a static invoke if it is still present during baseline code generation, but ensure that static invokes have no such check as last input in optimized compilations.

* | Replace String CharArray with internal uint16_t array.Jeff Hao2015-04-271-12/+79
|/ | | | | | | | | | | | Summary of high level changes: - Adds compiler inliner support to identify string init methods - Adds compiler support (quick & optimizing) with new invoke code path that calls method off the thread pointer - Adds thread entrypoints for all string init methods - Adds map to verifier to log when receiver of string init has been copied to other registers. used by compiler and interpreter Change-Id: I797b992a8feb566f9ad73060011ab6f51eb7ce01

| * Ensure inlined static calls perform clinit checks in Optimizing.Roland Levillain2015-04-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Calls to static methods have implicit class initialization (clinit) checks of the method's declaring class in Optimizing. However, when such a static call is inlined, the implicit clinit check vanishes, possibly leading to an incorrect behavior. To ensure that inlining static methods does not change the behavior of a program, add explicit class initialization checks (art::HClinitCheck) as well as load class instructions (art::HLoadClass) as last input of static calls (art::HInvokeStaticOrDirect) in Optimizing' control flow graphs, when the declaring class is reachable and not known to be already initialized. Then when considering the inlining of a static method call, proceed only if the method has no implicit clinit check requirement. The added explicit clinit checks are already removed by the art::PrepareForRegisterAllocation visitor. This CL also extends this visitor to turn explicit clinit checks from static invokes into implicit ones after the inlining step, by removing the added art::HLoadClass nodes mentioned hereinbefore.

* | [optimizing] Fix a bug in moving the null check to the user.Calin Juravle2015-04-221-1/+1
|/ | | | | | | When taking the decision to move a null check to the user we did not verify if the next instruction checks the same object. Change-Id: I2f4533a4bb18aa4b0b6d5e419f37dcccd60354d2
* Type MoveOperands.Nicolas Geoffray2015-04-151-1/+1
| | | | | | | | | The ParallelMoveResolver implementation needs to know if a move is for 64bits or not, to handle swaps correctly. Bug found, and test case courtesy of Serguei I. Katkov. Change-Id: I9a0917a1cfed398c07e57ad6251aea8c9b0b8506

| * [optimizing] Do not inline intrinsicsRazvan A Lupusoru2015-03-271-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The intrinsics generally have specialized code and the code for them may be faster than what can be achieved with inlining. Thus inliner should skip intrinsics. At the same time, easy methods are not worth intrinsifying: ie String length and isEmpty. Those can be handled by inliner with no problem and can actually lead to better code since call is not kept around through all of the optimizations.
