Move mirror::ArtMethod to native Optimizing + quick tests are passing, devices boot. 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.

ART: Clean up arm64 kNumberOfXRegisters usage. Avoid undefined behavior for arm64 stemming from 1u << 32 in loops with upper bound kNumberOfXRegisters. Create iterators for enumerating bits in an integer either from high to low or from low to high and use them for <arch>Context::FillCalleeSaves() on all architectures. Refactor runtime/utils.{h,cc} by moving all bit-fiddling functions to runtime/base/bit_utils.{h,cc} (together with the new bit iterators) and all time-related functions to runtime/base/time_utils.{h,cc}. Improve test coverage and fix some corner cases for the bit-fiddling functions.

Add Handle/HandleScope and delete SirtRef. 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

x86_64: JNI compiler Passed all tests from jni_compiler_test and art/test on host with jni_copiler. Incoming argument spill is enabled, entry_spills refactored. Now each entry spill contains data type size (4 or 8) and offset which should be used for spill. Assembler REX support implemented in opcodes used in JNI compiler. Please note, JNI compiler is not enabled by default yet (see compiler_driver.cc:1875).

Object model changes to support 64bit. Modify mirror objects so that references between them use an ObjectReference value type rather than an Object* so that functionality to compress larger references can be captured in the ObjectRefererence implementation. ObjectReferences are 32bit and all other aspects of object layout remain as they are currently. Expand fields in objects holding pointers so they can hold 64bit pointers. Its expected the size of these will come down by improving where we hold compiler meta-data. Stub out x86_64 architecture specific runtime implementation. Modify OutputStream so that reads and writes are of unsigned quantities. Make the use of portable or quick code more explicit. Templatize AtomicInteger to support more than just int32_t as a type. Add missing, and fix issues relating to, missing annotalysis information on the mutator lock. Refactor and share implementations for array copy between System and uses elsewhere in the runtime. Fix numerous 64bit build issues. Change-Id: I1a5694c251a42c9eff71084dfdd4b51fff716822

Entry point clean up. Create set of entry points needed for image methods to avoid fix-up at load time: - interpreter - bridge to interpreter, bridge to compiled code - jni - dlsym lookup - quick - resolution and bridge to interpreter - portable - resolution and bridge to interpreter Fix JNI work around to use JNI work around argument rewriting code that'd been accidentally disabled. Remove abstact method error stub, use interpreter bridge instead. Consolidate trampoline (previously stub) generation in generic helper. Simplify trampolines to jump directly into assembly code, keeps stack crawlable. Dex: replace use of int with ThreadOffset for values that are thread offsets. Tidy entry point routines between interpreter, jni, quick and portable. Change-Id: I52a7c2bbb1b7e0ff8a3c3100b774212309d0828e (cherry picked from commit 848871b4d8481229c32e0d048a9856e5a9a17ef9)
