Don't use dlopen on host for already loaded oat files.
Because the behavior of dlopen on the host is different then the

Shard classloader classes lock
Used to guard adding and removing classes.
Previously we used the class linker classes lock, but this had
a deadlock issue since the reference processor may need to acquire
the lock to mark the classes of a class loader. Another thread could
be blocked trying to access weak globals while also holding the
class linker classes lock.

Lambda closures created with the 'create-lambda' instruction
(termed "innate lambdas") can be turned into an object with 'box-lambda'.
This CL enables support for those kinds of lambdas to work with
'invoke-interface' by generating a proxy class for the lambda.

runtime: Add lambda box/unbox object equality
A lambda that is boxed with box-lambda is now stored as a weak reference
in a global runtime table (lambda::BoxTable). Repeatedly boxing the same
lambda closure value will always return the same java.lang.Object back.
Since there is no way to observe the address of an object, a GC can
happen and clean up the table of any dead boxed lambdas, which can also
shrink the table to prevent the memory use from growing too much.
(Note that a lambda closure is immutable, so hashing over it is
guaranteed safe.)

ART: JNI thread state transition optimization
This patch improves the JNI performance by removing the explicit acquiring and
releasing the mutator lock when a thread state transits between suspended and
runnable states.
The functions responsible for changing the state were found to be the costliest
part of the JNI. Originally, a thread needs to acquire a shared mutator lock by
a CAS instruction when entering the runnable state and also needs to release
the lock by a CAS when entering the native state from runnable. This patch
removes these CAS operations when a thread state transits between suspended and
runnable. A thread in the runnable state is considered to have shared ownership
of the mutator lock and therefore transitions in and out of the runnable state
have associated implication on the mutator lock ownership. Meanwhile, a barrier
is added to control suspending all threads from running.
JNI transition overhead was reduced by 25% on IA platform and by 17% on ARM
platform by this patch, while it has little impact on GC pause time (measured
with "suspend all histogram").

JDWP: asynchronous invoke command handling
The JDWP thread used to wait for the result of a method invocation
running in an event thread. But doing that prevents the JDWP thread
from processing incoming commands from the debugger if the event
thread gets suspended by a debug event occurring in another thread.
In Android Studio (or another IDE), this leads to the debugger being
blocked (with the famous message "Waiting until last debugger command
completes" of Android Studio / IntelliJ) because it is actually
waiting for the reply of its latest command while the JDWP thread
cannot process it.
This CL changes the way invoke commands (ClassType.InvokeCommand,
ClassType.NewInstance and ObjectReference.InvokeCommand) are handled
in the ART runtime.
The JDWP thread no longer waits for the event thread to complete the
method invocation. It now simply waits for the next JDWP command to
process. This means it does not send any reply for invoke commands,
except if the information given by the debugger is wrong. In this
case, it still sends a reply with the appropriate error code.
The event thread is now responsible for sending the reply (containing
the result and the exception object of the invoked method) before
going back to the suspended state.
In other words, we add special handling for invoke commands so they
are handled asynchronously while other commands remained handled
synchronously. In the future, we may want to handle all commands
asynchronously (using a queue of reply/event for instance) to remove
the special handling code this CL is adding.
Now the JDWP thread can process commands while a thread is invoking
a method, it is possible for the debugger to detach (by sending a
VirtualMachine.Dispose command) before the invocation completes. In
that situation, we must not suspend threads again (including the
event thread that executed the method) because they would all remain
suspended forever.
Also minor cleanup of the use of JDWP constants and update comments.

ART: Add entries_ lock for race condition
GCDaemon thread would visit incorrect RegType content when there is
another thread initializing classes.
Add a lock to protect entries_.

Wait for threads to finish unregistering
There was a race where Thread::join would return before the thread was
unregistered. This caused a problem with Daemons.stop since the thread
list could get deleted before the daemon thread was removed from list_.
This caused occasional "Request to unregister unattached thread"
errors and warnings.
The fix is to wait until threads finish registering before destroying
the thread list. The only threads which can be unregistering at this
point are the daemons we stopped earlier during the runtime shutdown
process. The issue is that thread join finishes before we remove the
thread from the thread list.
Also some cleanup.

Add JIT
Currently disabled by default unless -Xjit is passed in.
The proposed JIT is a method JIT which works by utilizing interpreter
instrumentation to request compilation of hot methods async during
runtime.
JIT options:
-Xjit / -Xnojit
-Xjitcodecachesize:N
-Xjitthreshold:integervalue
The JIT has a shared copy of a compiler driver which is accessed
by worker threads to compile individual methods.
Added JIT code cache and data cache, currently sized at 2 MB
capacity by default. Most apps will only fill a small fraction of
this cache however.
Added support to the compiler for compiling interpreter quickened
byte codes.
Added test target ART_TEST_JIT=TRUE and --jit for run-test.
TODO:
Clean up code cache.
Delete compiled methods after they are added to code cache.
Add more optimizations related to runtime checks e.g. direct pointers
for invokes.
Add method recompilation.
Move instrumentation to DexFile to improve performance and reduce
memory usage.

C++11 related clean-up of DISALLOW_..
Move DISALLOW_COPY_AND_ASSIGN to delete functions. By no having declarations
with no definitions this prompts better warning messages so deal with these
by correcting the code.
Add a DISALLOW_ALLOCATION and use for ValueObject and mirror::Object.
Make X86 assembly operand types ValueObjects to fix compilation errors.
Tidy the use of iostream and ostream.
Avoid making cutils a dependency via mutex-inl.h for tests that link against
libart. Push tracing dependencies into appropriate files and mutex.cc.
x86 32-bit host symbols size is increased for libarttest, avoid copying this
in run-test 115 by using symlinks and remove this test's higher than normal
ulimit.

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.

Use memory chunks for monitors on LP64
Monitor IDs in lock words are only 30b. On a 32b system that works
fine, as memory is usually aligned enough that shifting works out.
On 64b systems, the virtual memory space is too large for that.
This adds memory chunks into which we allocate the monitors so that
we have base_addr + offset and can use the offset as the monitor ID.
To allow for relatively compact but growable storage, we use a list
of chunks.
Added a global lock for the monitor pool.

- 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.

functionality won't silently break. For example, if there's a gap and
a large object is allocated in that gap, the large object is
incorrectly part of the immune region and the marking breaks.

Move modify_ldt_lock into global lock order.
Mutex modify_ldt_lock was being removed during runtime shutdown while
daemons thread may still detach. Avoid this by placing in global lock
order.
This fixes cts dalvik vm-tests-tf that hang on some x86 devices.
By irogers: also, tidy global locks to agree with enum constants and
add extra verification that the global annotalysis order agrees with
the LockLevel order. Bumped the oat version and moved the locks as
LockLevel additions previously caused entrypoints to be moved. Make
unattached lock not handle the default mutex level case by moving the
allocated thread ids lock into the global order.

Use WaitHoldingLocks in ReferenceProcessor::GetReferent.
The caller may be holding other locks, so we must use this or else
we get bad mutexes held errors. Also added a lock level for the
reference processor.

Add monitor deflation.
We now deflate the monitors when we perform a heap trim. This causes
a pause but it shouldn't matter since we should be in a state where
we don't care about pauses. Memory savings are hard to measure.
Fixed integer overflow bug in GetEstimatedLastIterationThroughput.

Refactor deoptimization support in debugger
This CL prepares breakpoint support for inlined methods where we'll have to
deoptimize everything.
We move deoptimization-related information to Dbg class only (deoptimization
request queue, full deoptimization event count and deoptimization lock). We
replace MethodInstrumentionRequest by DeoptimizationRequest. This is used to
know which kind of deoptimization is required for a particular event.
It also simplifies lock ordering a bit during event setup: we no longer need to
hold the deoptimization lock while holding the breakpoint lock. Moreover, the
deoptimization lock should be held only after the event list lock.

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.

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.

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..

Inflate contended lock word by suspending owner.
Bug 6961405.
Don't inflate monitors for Notify and NotifyAll.
Tidy lock word, handle recursive lock case alongside unlocked case and move
assembly out of line (except for ARM quick). Also handle null in out-of-line
assembly as the test is quick and the enter/exit code is already a safepoint.
To gain ownership of a monitor on behalf of another thread, monitor contenders
must not hold the monitor_lock_, so they wait on a condition variable.
Reduce size of per mutex contention log.
Be consistent in calling thin lock thread ids just thread ids.
Fix potential thread death races caused by the use of FindThreadByThreadId,
make it invariant that returned threads are either self or suspended now.
Code size reduction on ARM boot.oat 0.2%.
Old nexus 7 speedup 0.25%, new nexus 7 speedup 1.4%, nexus 10 speedup 2.24%,
nexus 4 speedup 2.09% on DeltaBlue.

Polish the lock contention logging.
- Make the code compilable.
- Surround the code with kLogLockContentions instead of #ifdef CONTENTION_LOGGING.
- Dump contended locks before never-contended locks for better log readability.
- Change the wait time unit from ms to us for better precision.

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.
