Support directly invoking interface default methods
With the Java 8 Language one is allowed to directly call default
interface methods of interfaces one (directly) implements through the
use of the super keyword. We support this behavior through the
invoke-super opcode with the target being an interface.
We add 3 tests for this behavior.
Currently only supports slow-path interpreter.
Invoke-super is currently extremely slow.

ART: Refactor verifier callbacks
Change the return type of MethodVerified to void. It was never
used anyways.
Remove the callbacks calls from the core of the verifier (Verify()).
Instead, make the convenience functions do the work, and add a
parameter to supply the callback so that the verifier becomes
independent of the Runtime-stored one.
Fix up calls that now need to provide a callback, but leave places
that only run the verifier to get metadata (e.g., register type data,
lock state) without callback. This avoids callback calls when in JIT
mode.

interpreter: Add experimental lambda opcodes for invoke/create-lambda
These opcodes are not yet fully specified, and *will* change before they become shippable.
Do not write production code against experimental opcodes.
--
Implement partial interpreter support for new dex instructions invoke/create-lambda, and a
new opcode format 25x.
* Does not verify, in fact verification will soft fail when we see those opcodes.
* Compilers will punt to interpreter since they don't support new opcodes.
* As there is no way to capture/liberate variables yet, the "closure" is just
an ArtMethod for the time being.
All new opcodes are disabled by default, use runtime option -Xexperimental-lambdas to enable them.
For example:
dalvikvm ... -Xexperimental-lambdas ...
dex2oat --runtime-arg -Xexperimental-lambdas ...

Add support for nested method verifiers
Can occur in the following scenario:
MethodVerifier::Verify -> MethodVerifier::GetStaticField ->
ResolveFieldJLS -> ThrowNoSuchFieldError -> EnsureInitialized ->
VerifyClass
Also fixed another case where we can be requested to dump for ANR
while we are suspended in one of the AllowSuspension points.

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.

Fix incompatible class change error for JIT stress mode
There was a problem with miranda methods, when we would dequicken to
one of these, it wouldn't resolve as virtual during the method
lowering resolve. The solution is to try resolving as interface if we
fail to resolve as virtual.
Fixed a bug in dequickening where unreachable register lines with
quick invokes would cause CHECK failuers. In this case we punt to the
interpreter (test 435-try-*).
Added test regression test. Example failure:
java.lang.IncompatibleClassChangeError: The method
'void Main$TheInterface.m()' was expected to be of type virtual but
instead was found to be of type interface (declaration of
'java.lang.reflect.ArtMethod' appears in

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.

Don't allow suspension from FindLocksAtDexPc
Transitioning to suspended from runnable sometimes runs dump
checkpoints in ThreadStress which can cause deadlocks. This happens
since FindLocksAtDexPC runs the verifier which calls
AllowThreadSuspension. This results in a blocked thread which holds
the monitor lock, and if another thread tries to do a monitor enter,
it deadlocks while holding the mutator lock (assuming the GC is
suspending all).
The fix for avoiding this deadlock is not calling
AllowThreadSuspension from FindLocksAtDexPc.

ART: Fix verification of constructors.
Summary:
A constructor must call its superclass constructor. However, if one
replaces the invoke-direct superclass.<init>() instruction with a
variety of instructions, the verifier would NOT complain that the
superclass constructor hadn't been called.
Detailed explanation:
This was because if we are verifying the return-void insn of a
constructor, then we check that the register line doesn't contain a
register with an UninitializedThis type. With a method like follows:
Class.<init>()V:
return-void
Then we hit the return-void, see the UninitializedThis, and fail the
method. However, with a method like follows:
Class.<init>()V:
nop
return-void
Any insn that continues or branches onto a return-void instruction will
mark all of the registers as Conflict. This meant that the check in
return-void for an UninitializedThis residing the register line would
_always_ pass if there were any insns before it - the entire line had
been set to Conflict.
The fix is to bring the check for an UninitializedThis forward to the
point just before we set all registers to Conflict, if we're about to
hit a return-void insn in a constructor. It still needs to be done
again in the verification of return-void itself, to avoid the solo
return-void case.
This patch also deals with the case where the only remaining
UninitializedThis reference is overwritten, to avoid a method like the
following from getting through verification:
Class.<init>()V:
const/4 v0, 0
return-void

ART: Reject branch/switch/throw to move-result.
move-result* instructions must occur after invoke instructions,
however it was still possible to branch or switch to a move-result*
instruction with creative DEX manipulation. The verifier now rejects
this situation, as well as having a move-result* instruction as the
first instruction in a try block's handler. This now ensures that
move-result* must happen dynamically after an invoke, not just
statically.

Fix stale root error in verifier
There was a stale root error caused by the static roots from
the reg types. These were visitied if there was an active verifier
in the method_verifiers_ but this is not always the case when a GC
is run. The fix is to always visit the static method verifier roots.
This only showed up as a bug without an image since these roots
were primitive classes and always in the image, and therefore
didn't ever need to be updated due to moving GC.

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.

Make the specification of when we need precise constants more precise.
Means that oatdump output showing values for deoptimization actually reflects
what we see at runtime.
Also, doesn't do precise in the case of determining methods and fields for the
quickened case, which may be an occasional performance win.

Fix an outstanding compaction bug in interpreter.
Fixed a bug in DoFieldPut where the FieldHelper GetType could cause
thread suspension which would result in a stale obj.
Added more handles in the class linker to facilitate moving fiels
and methods in the future.
Removed un-necessarly passing handle references since these are value
types and don't need to be passed by reference.
Added a special NullHandle type which allows null handles without a
handle scope.

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.

Use imprecise constants at compilation time.
During veriifcation, we create constant types for the following instructions:
const/4, const/16, const and const/high16. We used to create "precise" constant
types for each constant we process in the method being verified. Though precise
constants are only useful for deoptimization which happens at runtime.
This CL now creates "imprecise" constant types at compilation time. Since it
reduces the number of constant types we create during verification, it should
also reduce the amount of time spent in verification at compilation time.

Move compiler code out of method verifier.
We want to detect small methods for inlining at the end of
the method verification. Instead of adding more compiler
code to the runtime, we create a callback from the runtime
into the compiler, so that we can keep the code there.
Additionally, we move the compiler-related code that was
already in the method verifier to the compiler since it
doesn't really belong to the runtime in the first place.

Enable moving classes.
Slight reduction in Zygote size, memory savings are in the noise.
Before: Zygote size: 8739224
After: Zygote size: 8733568
Fixed a bug where we didn't set the concurrent start bytes after
switching the allocator from bump pointer to ROSAlloc in the
zygote. This caused excessive memory usage.
Added the method verifiers as roots to fix an issue caused by
RegTypes holding a Class*.
Added logic to clear card table in the SemiSpace collector, this
reduces DalvikOther from ~2400k -> ~1760k when using the SemiSpace
collector.
Added a missing lock to the timing loggers which caused a rare
one time crash in std::set.

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..

Prevent verifier from creating unused compilation data.
The verifier used to create data which may be unused like GC map. This is the
case for non-compiled method (which are interpreted). This CL aims to optimize
this.
Here are the changes:
- Move compilation selection to MethodVerifier::IsCandidateForCompilation.
- Compiler and verifier use this method to know if a method must be compiled.
- Only create compilation data while compiling using Runtime::IsCompiler.
- Do not create internal structures concerning GC map, ... in Runtime::Init and
Runtime::Shutdown when we are not compiling.
- Checks we are compiling when accessing these structures.
- Add missing destruction of MethodVerifier::safecast_map_lock_ and
MethodVerifier::safecast_map_ in Runtime::Shutdown.
- Call Runtime::Shutdown just before Runtime instance is destroyed to avoid a
crash.
- Add missing "GUARDED_BY" macro for MethodVerifier::rejected_classes_ field.
- Add "has_check_casts" to avoid the safecast pass if there is no check-cast
instruction.
- Add "has_virtual_or_interface_invokes" to avoid the devirtualization pass if
there is no invoke-virtual/range nor invoke-interface/range instructions.
