Move image intern table into image Previously we recreated this intern table during runtime startup. This added 50-100ms of boot time. Fixed bug where we didn't copy over hashcodes into the image.

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.

Add mark compact collector. The mark compact collector is a 4 phase collection, doing a normal full mark_sweep, calculating forwarding addresses of objects in the from space, updating references of objects in the from space, and moving the objects in the from space. Support is diabled by default since it needs to have non movable classes and field arrays. Performance numbers is around 50% as fast. The main advantage that this has over semispace is that the worst case memory usage is 50% since we only need one space isntead of two. TODO: Make field arrays and classes movable. This causes complication since Object::VisitReferences relies on these, so if we update the fields of an object but another future object uses this object to figure out what fields are reference fields it doesn't work.

Remove deprecated WITH_HOST_DALVIK. Bug: 13751317 Fix the Mac build: - disable x86 selector removal that causes OS/X 10.9 kernel panics, - madvise don't need does zero memory on the Mac, factor into MemMap routine, - switch to the elf.h in elfutils to avoid Linux kernel dependencies, - we can't rely on exclusive_owner_ being available from other pthread libraries so maintain our own when futexes aren't available (we can't rely on the OS/X 10.8 hack any more), - fix symbol naming in assembly code, - work around C library differences, - disable backtrace in DumpNativeStack to avoid a broken libbacktrace dependency, - disable main thread signal handling logic, - align the stack in stub_test, - use $(HOST_SHLIB_SUFFIX) rather than .so in host make file variables. Not all host tests are passing on the Mac with this change. dex2oat works as does running HelloWorld. Change-Id: I5a232aedfb2028524d49daa6397a8e60f3ee40d3

Enable reading page map without lock in RosAlloc::BulkFree Enabling this flag greatly reduces how much time was spent in the GC. It was not done previously since it was regressing MemAllocTest. With these RosAlloc changes, the benchmark score no longer regresses after we enable the flag. Changed Run::AllocSlot to only have one mode of allocation. The new mode is finding the first free bit in the bitmap. This was previously the slow path but is now the fast path. Some optimizations which enabled this include always having the alloc bitmap bits which correspond to invalid slots be set to 1. This prevents us from needing a bound check since we will never end up allocating there. Changed revoking thread local buffer to point to an invalid run. The invalid run is just a run which always has all the allocation bits set to 1. When a thread attempts to do a thread local allocation from here it will always fail and go slow path. This eliminates the need for a null check for revoked runs. Changed zeroing of memory to happen during free, AllocPages should always return zeroed memory. Added prefetching which happens when we allocate a run. Some refactoring to reduce duplicated code. Ergonomics changes: Changed kStickyGcThroughputAdjustment to 1.0, this helps reduce GC time. Measurements (3 samples per benchmark): Before: MemAllocTest scores: 3463, 3445, 3431 EvaluateAndApplyChanges score | total GC time Iter 1: 3485, 23.602436s Iter 2: 3434, 22.499882s Iter 3: 3483, 23.253274s After: MemAllocTest scores: 3495, 3417, 3409 EvaluateAndApplyChanges score | total GC time: Iter 1: 3375, 17.463462s Iter 2: 3358, 16.185188s Iter 3: 3367, 15.822312s Bug: 8788501 Bug: 11790317 Bug: 9986565 Change-Id: Ifd273a054824028dabed27c07c081dde1816f93c

Replace ObjectSet with LargeObjectBitmap. Speeds up large object marking since large objects no longer required a lock. Changed the GCs to use the heap bitmap for marking objects which aren't in the fast path. This eliminates the need for a MarkLargeObject function. Maps before (10 GC iterations): Mean partial time: 180ms Mean sticky time: 151ms Maps after: Mean partial time: 161ms Mean sticky time: 101ms Note: the GC durations are long due to recent ergonomic changes and because the fast bulk free hasn't yet been enabled. Over 50% of the GC time is spent in RosAllocSpace::FreeList. Bug: 13571028 Change-Id: Id8f94718aeaa13052672ccbae1e8edf77d653f62

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
