Move to newer clang annotations Also enable -Wthread-safety-negative. Changes: Switch to capabilities and negative capabilities. Future work: Use capabilities to implement uninterruptible annotations to work with AssertNoThreadSuspension. Bug: 20072211 Change-Id: I42fcbe0300d98a831c89d1eff3ecd5a7e99ebf33

Fix DCHECK failures from Class::VisitFieldRoots We now use GetDeclaringClassUnchecked when marking roots to fix flaky test failures. Fixed a race condition in root marking where we could have non zero field array length with a null pointer. Fixed a race condition where we could be marking roots before FixupTemporaryDeclaringClass had finished. The solution is to only do the declaring class CHECK if we are at least resolved. Fixed JDWP tests by changing FieldId / MethodId to be 64 bits. Also some cleanup. Change-Id: Ibac09519860d93c3f68a5cc964bbc91dc10a279a

Refactor and improve GC root handling 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.

Force inlining on trivial accessors. Make volatility for GetFieldObject a template parameter. Move some trivial mirror::String routines to a -inl.h. Bug: 14285442 Change-Id: Ie23b11d4f18cb15a62c3bbb42837a8aaf6b68f92

Enable annotalysis on clang ART builds. Fix clang build errors aswell as restructure locking/mutex code for correct thread safety analysis support. Reorder make dependencies so that host builds build first as they should provide better compilation errors than target. Remove host's use of -fno-omit-frame-pointer as it has no value with correct use of CFI, which we should have. Change-Id: I72cea8da9a3757b1a0b3acb4081feccb7c6cef90

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
