Fix Class::IsInSamePackage to not read beyond the end of a StringPiece. Fix length of string piece to be size_type rather than int because expecting negatively sized strings is a bad idea and we should use unsigned types to defensively guard against mistakes. Remove max_size and capacity since the return type is inconsistent between Google and the STL, and we don't need the functions. Add a bound check in libartd to operator[] accesses.

Compile time performance improvements focusing on interpret-only. Reduce virtual method dispatch in the method verifier and make more code inline-able. Add a StringPiece with const char* equality operator to avoid redundant StringPieces and strlens. Remove back link from register line to verifier and pass as argument to reduce size of RegisterLine. Remove instruction length from instruction flags and compute from the instruction, again to reduce size. Add suspend checks to resolve and verify to allow for more easy monitor inflation and reduce contention on Locks::thread_list_suspend_thread_lock_. Change ThrowEarlierClassFailure to throw pre-allocated exception. Avoid calls to Thread::Current() by passing self. Template specialize IsValidClassName. Make ANR reporting with SIGQUIT run using checkpoints rather than suspending all threads. This makes the stack/lock analysis less lock error prone. Extra Barrier assertions and condition variable time out is now returned as a boolean both from Barrier and ConditionVariable::Wait. 2 threaded host x86-64 interpret-only numbers from 341 samples: Before change: Avg 176.137ms 99% CI 3.468ms to 1060.770ms After change: Avg 139.163% 99% CI 3.027ms to 838.257ms Reduction in average compile time after change is 20.9%. Slow-down without change is 26.5%. Bug: 17471626 - Fix bug where RegTypeCache::JavaLangObject/String/Class/Throwable could return unresolved type when class loading is disabled.

Don't scan image space when starting runtime. Bug 10432288. Find Classes and Strings from dex caches lazily rather than when the image is loaded. Make class status changes do notifies when there can be waiters. For Class lookup there's a pathology if we always search dex caches and so after 1000 failures move all classes into the class table. Be consistent in using "const char*" for class linker descriptors as this most easily agrees with the type in the dex file. Improve the intern run-test so that it has a case of a literal contained in the image. Modify image_test to allow any valid lock word rather than expecting 0, ideally we wouldn't see inflated monitors but we do due to NotifyAll (see bug 6961405).

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. Builds in the art directory should behave as before, building everything including tests. Change-Id: Ic6b1151e5ed0f823c3dd301afd2b13eb2d8feb81
