Initialize native loader before starting runtime
Loading public libraries before everything else
to prevent situation when libssl.so gets into
libopenjdk.so load group which then prevented
from unloading by a global library referencing
the very same libssl.so

need for LoadNativeLibrary() and callers to pass

Use isolated namespaces for app native libs
Linker namespaces provide necessary level
of isolation for application native libraries.
The native libraries will no longer be able to
mistakenly depend on platform private libraries
like /system/lib/libssl.so
This change creates one namespace for each instance
of class-loader and uses it when loading native libraries.
For backwards compatibility with older apps we keep
using default namespace and LD_LIBRARY_PATH if target
sdk version is <= 23. (currently set to 0 for testing)

Unify ART's various implementations of bit_cast.
ART had several implementations of art::bit_cast:
1. one in runtime/base/casts.h, declared as:
template <class Dest, class Source>
inline Dest bit_cast(const Source& source);
2. another one in runtime/utils.h, declared as:
template<typename U, typename V>
static inline V bit_cast(U in);
3. and a third local version, in runtime/memory_region.h,
similar to the previous one:
template<typename Source, typename Destination>
static Destination MemoryRegion::local_bit_cast(Source in);
This CL removes versions 2. and 3. and changes their callers
to use 1. instead. That version was chosen over the others
as:
- it was the oldest one in the code base; and
- its syntax was closer to the standard C++ cast operators,
as it supports the following use:
bit_cast<Destination>(source)
since `Source' can be deduced from `source'.

Fix 2 new sets of clang compiler warnings.
Fix issues that are flagged by -Wfloat-equal and -Wmissing-noreturn.
In the case of -Wfloat-equal the current cases in regular code are deliberate,
so the change is to silence the warning. For gtest code the appropriate fix is
to switch from EXPECT_EQ to EXPECT_(FLOAT|DOUBLE)_EQ.
The -Wmissing-noreturn warning isn't enabled due to a missing noreturn in
gtest. This issue has been reported to gtest.

ART: Use StackReference in Quick Stack Frame
The method reference at the bottom of a quick frame is a stack
reference and not a native pointer. This is important for 64b

parameter instead of mirror::ArtMethod**. Make changes to

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. For now the type remains called
UniquePtr.
Make dalvik compile with clang on the host, move its build to C++11.

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.

ART: A workaround for a wrongly-read caller's frame
The quick-trampoline treats caller's frame in a different way
then it was formed by quck-invoke stub for hard float ABI targets
such as x86_64 and aarch64. The patch workarounds the issue of
wrongly-read stack arguments due to no contract between quick-invoke
stub and quick-trampoline/shadow-frame-builder regarding the reg-
spill area.

Fix wrong handling of Generic JNI not finding native method.
Code did not properly call JNIMethodEnd, such that locks etc
where not correctly handled.
Add a test case to jni_compiler_test.

Cleanup transaction support
Updates Thread::CreateInternalStackTrace to support both transactional and
non-transactional modes using template.
Generalizes non-transactional mode for invariant fields (which are set only
once).
Removes ArrayLog::VisitRoots as we never create Array logs of ObjectArray. As
ObjectArray elements are set using Object::SetFieldObject, they are already
recorded in the object logs: the object is the array itself and the offset
corresponds to the element index in this array. And also checks we never log
ObjectArray in array logs.
Fixes location of thrown exception when calling native method during class
initialization.

Refactor reflective method invocation.
Move invocation code out of JNI internal into reflection, including ArgArray
code. Make reflective invocation use the ArgArray to build arguments rather
than allocating a jvalue[] and unboxing arguments into that.
Move reflection part of jni_internal_test into reflection_test.
Make greater use of fast JNI.

Generic JNI implementation for x86_64
Starting implementation for generic JNI on x86_64. Frames are of
large static size (>4K) right now, should be compacted later. Passes

Avoid std::string allocations for finding an array class.
Introduce ClassLinker::FindArrayClass which performs an array class lookup
given the element/component class. This has a 16 element cache of recently
looked up arrays.
Pass the current thread to ClassLinker Find .. Class routines to avoid calls
to Thread::Current().
Avoid some uses of FindClass in the debugger where WellKnownClasses is a
faster and more compacting GC friendly alternative.

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.

Add missing SIRT to LoadNativeLibrary.
When we transition to kWaitingForJniOnLoad, we are suspended and
a GC can occur. This caused issues since classloaders are movable.

Compacting collector.
The compacting collector is currently similar to semispace. It works by
copying objects back and forth between two bump pointer spaces. There
are types of objects which are "non-movable" due to current runtime
limitations. These are Classes, Methods, and Fields.
Bump pointer spaces are a new type of continuous alloc space which have
no lock in the allocation code path. When you allocate from these it uses
atomic operations to increase an index. Traversing the objects in the bump
pointer space relies on Object::SizeOf matching the allocated size exactly.
Runtime changes:
JNI::GetArrayElements returns copies objects if you attempt to get the
backing data of a movable array. For GetArrayElementsCritical, we return
direct backing storage for any types of arrays, but temporarily disable
the GC until the critical region is completed.
Added a new runtime call called VisitObjects, this is used in place of
the old pattern which was flushing the allocation stack and walking
the bitmaps.
Changed image writer to be compaction safe and use object monitor word
for forwarding addresses.
Added a bunch of added SIRTs to ClassLinker, MethodLinker, etc..
TODO: Enable switching allocators, compacting on background, etc..

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.
