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.

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

Add reserve area to allocation stacks. This fixes an issue with heap verification which was caused when the allocation stack overflowed. This resulted in heap verification failures since we were storing the newly allocated object in a handle scope without having it be live either in the live bitmap or allocation stack. We now push the object in the reserve area before we do a GC due to allocation stack overflow. Change-Id: I83b42c4b3250d7eaab1b49e53066e21c8656a740

Compatibility layer to transition from UniquePtr to std::unique_ptr. Use ART_WITH_STLPORT (enabled for the target) to cause the use of UniquePtr, for the host switch to std::unique_ptr.

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

More parallel GC, rewritten parallel mark stack processing. Card scanning may now be done in parallel. This speeds up sticky and reduces pause times for all GC types. Speedup on my mako (ritz perf): Average pause time for sticky GC (~250 samples): Without parallel cards scanning enabled: 2.524904215ms Parallel card scanning (num_gc_threads_): 1.552123552ms Throughput (~250 samples): Sticky GC throughput with parallel card scanning: 69MB/s Sticky GC throughput without parallel card scanning: 51MB/s Rewrote the mark stack processing to be LIFO and use a prefetch queue like the non parallel version. Cleaned up some of the logcat printing for the activity manager process state listening. Added unlikely hints to object scanning since arrays and classes are scanned much less often than normal objects. Fixed a bug where the number of GC threads was clamped to 1 due to a bool instead of a size_t. Fixed a race condition when we added references to the reference queues. Sharded the reference queue lock into one lock for each reference type (weak, soft, phatom, finalizer). Changed timing splits to be different for processing gray objects with and without mutators paused since sticky GC does both. Mask out the class bit when visiting fields as an optimization, this is valid since classes are held live by the class linker. Partially completed: Parallel recursive mark + finger.

Remove sorted variable in allocation stacks. Speeds up allocations, mark stack processing non parallel. This is safe to do since the pre/post GC heap verification is the only place where we sort the allocation and live stacks and this is done with mutators suspended.

Create separate Android.mk for main build targets The runtime, compiler, dex2oat, and oatdump now are in seperate trees to prevent dependency creep. They can now be individually built without rebuilding the rest of the art projects. dalvikvm and jdwpspy were already this way.
