Write conflict tables in image
Add image sections for runtime methods and conflict tables. This
makes it that we do not need to fake up a length prefixed array
for runtime methods.
Reduces .art private dirty and PSS.
System wide .art PSS goes from 32.5MB to 30.5MB after system boot.
Business card .art private dirty goes from 588K to 504K.
Increases image size by ~100K.

Pack stack map entries on bit level to save space.
Use only the minimum number of bits required to store stack map data.
For example, if native_pc needs 5 bits and dex_pc needs 3 bits, they
will share the first byte of the stack map entry.
The header is changed to store bit offsets of the fields rather than
byte sizes. Offsets also make it easier to access later fields without
calculating sum of all previous sizes.
All of the header fields are byte sized or encoded as ULEB128 instead
of the previous fixed size encoding. This shrinks it by about half.
It saves 3.6 MB from non-debuggable boot.oat (AOSP).
It saves 3.1 MB from debuggable boot.oat (AOSP).
It saves 2.8 MB (of 99.4 MB) from /system/framework/arm/ (GOOG).
It saves 1.0 MB (of 27.8 MB) from /system/framework/oat/arm/ (GOOG).
Field loads from stackmaps seem to get around 10% faster.

Add an ImtConflictTable to better resolve IMT conflicts.
- Attach a ImtConflictTable to conflict runtime ArtMethod.
- Initially 0, a new one will be created at the first hit of
the conflict method.
- If the assembly code does not find a target method in the table,
we will create a new one again, copying the data from the previous
table and adding the new mapping.
Implemented for arm/arm64/x86/x64.

Also templatize ResolveMethod with a version always checking

Correct exception behavior for default methods
Default methods are defined to throw an IncompatibleClassChangeError
(ICCE) when they are called and there is no "best" implementation.
Previously we would simply throw an ICCE during class loading as soon
as we noticed that this would happen if called. This makes us wait
until we actually attempt to execute the method. Furthermore, this
allows us to use other, non-conflicting, methods on the object as
normal.
Furthermore, this makes us correctly throw AbstractMethodErrors in
cases where all default implementations of a method are overridden by
abstract declarations.
Adds 3 tests for this new behavior.

Fix deoptimization with pending exception
When deoptimizing the stack, we set a fake exception in the current
Thread* (see method Thread::GetDeoptimizationException). On the next
exception check, the QuickExceptionHandler will deoptimize the stack.
The issue is when we deoptimize while an exception is already pending
in the current Thread*: setting the fake exception will clobber the
pending exception which is not correct. This happens in the
artQuickToInterpreterBridge when returning from the interpreter and
we want to deoptimize the stack for debugging (like single-stepping).
This CL saves the pending exception before asking for deoptimization.
Then the exception is restored just before executing the deoptimized
frames with the interpreter.
Also cleans up the way we save deoptimization context (return value
and pending exception).

Cache stack map encoding
Operations on CodeInfo and StackMap objects repeatedly read encoding
information from the MemoryRegion. Since these are 3-bit-loads of
values that never change, caching them can measurably reduce compile
times.
According to benchmarks, this patch saves 1-3% on armv7, 2-4% on x86,
and 0-1% on x64.

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'.

Daniel Mihalyi <daniel.mihalyi@mattakis.com> |
JDWP: Optimized single step during debugging
For single stepping full deoptimization and undeoptimizations were
performed with significant overhead, because every code will be
executed in interpreted mode during a single step, even if it is not
strictly required.
For example, if we have a computation heavy method call and we would
like to step over it, that method (and all the methods called from it)
will run in interpreter mode. This can take so long in some cases
(e.g. multiple minutes) that it makes debugging process unusable.
The solution for this limitation is not using full deoptimizations for
single steps and force interpreter only for those methods that we are
about to step into, and require stack deoptimization before step outs.

ART: Change x86 long param ABI (Quick/JNI/Opt)
Ensure that we don't pass a long parameter across the last register
and the stack: skip the register and allocate it only on the stack.
This was requested to simplify the optimizing compiler code
generation for x86.
Optimizing (Baseline) compiler support for x86 longs:
- Remove QuickParameter from Location, as there are no longer any uses
of it.
Bump oat.h version because we changed an ABI again.
I changed IsParamALong() to return false for argument 0 (this argument).
I am not sure why it differed from all other tests.
I have not tested on ARM. I followed Nicolas's suggestions for setting
the value of kSplitPairAcrossRegisterAndStack for different

Fix handling of long argument spanning register/memory.
Comment in arm_lir.h says:
* If a 64-bit argument would span the register/memory argument
* boundary, it will instead be fully passed in the frame.
This change implements such logic for all platforms. We still need
to pass the low part in register as well because I haven't ported
the jni compilers (x86 and mips) to it.
Once the jni compilers are updated, we can remove the register
assignment.
Note that this greatly simplifies optimizing's register allocator
by not having to understand a long spanning register and memory.

Support proxy method in StackVisitor::GetThisObject
Adds function artQuickGetProxyThisObject which returns the 'this'
object of the proxy method using the QuickArgumentVisitor. Since
proxy methods have the same layout than the kRefsAndArgs runtime
method and 'this' is the 1st method argument, it is located in the
first GPR.

Change 64 bit ArtMethod fields to be pointer sized
Changed the 64 bit entrypoint and gc map fields in ArtMethod to be
pointer sized. This saves a large amount of memory on 32 bit systems.
Reduces ArtMethod size by 16 bytes on 32 bit.
Total number of ArtMethod on low memory mako: 169957
Image size: 49203 methods -> 787248 image size reduction.
Zygote space size: 1070 methods -> 17120 size reduction.
App methods: ~120k -> 2 MB savings.
Savings per app on low memory mako: 125K+ per app
(less active apps -> more image methods per app).
Savings depend on how often the shared methods are on dirty pages vs
shared.
TODO in another CL, delete gc map field from ArtMethod since we
should be able to get it from the Oat method header.

ARM: Use hardfp calling convention between java to java call.
This patch default to use hardfp calling convention. Softfp can be enabled
by setting kArm32QuickCodeUseSoftFloat to true.
We get about -1 ~ +5% performance improvement with different benchmark
tests. Hopefully, we should be able to get more performance by address the left
TODOs, as some part of the code takes the original assumption which is not
optimal.
DONE:
1. Interpreter to quick code
2. Quick code to interpreter
3. Transition assembly and callee-saves
4. Trampoline(generic jni, resolution, invoke with access check and etc.)
5. Pass fp arg reg following aapcs(gpr and stack do not follow aapcs)

7. Quick code method entry
8. Quick code method invocation
9. JNI compiler

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.

AArch64: Clean up CalleeSaveMethod frame and the use of temp registers.
CalleeSaveMethod frame size changes :
SaveAll : 368 -> 176
RefOnly : 176 -> 96
RefsAndArgs : 304 -> 224
JNI register spill size changes :
160 -> 88
In the transition assembly, use registers following the rules:
1. x0-x7 as temp/argument registers.
2. IP0, IP1 as scratch registers.
3. After correct type of callee-save-frame has been setup, all registers
are scratch-able(probably except xSELF and xSUSPEND).
4. When restore callee-save-frame, IP0 and IP1 should be untouched.
5. From C to managed code, we assume all callee save register in AAPCS
will be restored by managed code except x19(SUSPEND).
In quick compiler:
1. Use IP0, IP1 as scratch register.
2. Use IP1 as hidden argument register(IP0 will be scratched by
trampoline.)

ART: Generalize code to find PC for artInvokeInterfaceTrampoline
This allows to determine target method when the interface method has
no dex index, now also for X86-64 and ARM64.
Add constexpr functions to callee_save_frame.h to have compile-time
sizes of callee-save frames. Add a test that ensures they agree
with computations by the corresponding ArtMethod methods.
Move some instruction-set functions into the header file to allow
inlining them. Move arch-specific pointer sizes and alignment sizes
out of globals.h to instruction_set.h to reduce dependencies.

x86_64: Hard Float ABI support in QCG
This patch shows our efforts on resolving the ART limitations:
- passing "float"/"double" arguments via FPR
- passing "long" arguments via single GPR, not pair
- passing more than 3 agruments via GPR.
Work done:
- Extended SpecialTargetRegister enum with kARG4, kARG5, fARG4..fARG7.
- Created initial LoadArgRegs/GenDalvikX/FlushIns version in X86Mir2Lir.
- Unlimited number of long/double/float arguments support
- Refactored (v2)

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
architectures, where the notions do not coincide.
Change key methods to have StackReference<mirror::ArtMethod>*
parameter instead of mirror::ArtMethod**. Make changes to
invoke stubs for 64b archs, change the frame setup for JNI code
(both generic JNI and compilers), tie up loose ends.
Tested on x86 and x86-64 with host tests. On x86-64, tests succeed
with jni compiler activated. x86-64 QCG was not tested.
Tested on ARM32 with device tests.
Fix ARM64 not saving x19 (used for wSUSPEND) on upcalls.
Tested on ARM64 in interpreter-only + generic-jni mode.
Fix ARM64 JNI Compiler to work with the CL.

Restore the args in the invoke trampoline slow paths.
Previously, there were errors caused by not restoring the args for
the slow path in artInvokeInterfaceTrampoline and artInvokeCommon. The
slow path in artInvokeInterfaceTrampoline occurs when you attempt
to do an interface dispatch of a method in another dex file. The slow
path in artInvokeCommon occurs when the method in dex cache is not
already resolved.
Since FindMethodFromCode may resolve a method, it can occasionally
cause thread suspension/GC. If a moving GC occurred at this point it
resulted in this_object being invalid after the trampoline returned
the code pointer. This caused a native crash in one of the money runs
since there was an unbundeled app which did a List.iterator call.

Remove blacklist
Removes the class initialization blacklist and use transaction to detect and
revert class initialization attempting to invoke native method. This only
concerns class initialization happening at compilation time when generating an
image (like boot.art for the system).
In transactional mode, we log every object's field assignment and array update.
Therefore we're able to abort a transaction to restore values of fields and
array as they were before the transaction starts. We also log changes to the
intern string table so we can restore its state prior to transaction start.
Since transactional mode only happens at compilation time, we don't need to log
all these changes at runtime. In order to reduce the overhead of testing if
transactional mode is on/off, we templatize interfaces of mirror::Object and
mirror::Array, respectively responsible for setting a field and setting an
array element.
For various reasons, we skip some specific fields from transaction:
- Object's class and array's length must remain unchanged so garbage collector
can compute object's size.
- Immutable fields only set during class loading: list of fields, method,
dex caches, vtables, ... as all classes have been loaded and verified before a
transaction occurs.
- Object's monitor for performance reason.
Before generating the image, we browse the heap to collect objects that need to
be written into it. Since the heap may still holds references to unreachable
objects due to aborted transactions, we trigger one collection at the end of
the class preinitialization phase.
Since the transaction is held by the runtime and all compilation threads share
the same runtime, we need to ensure only one compilation thread has exclusive
access to the runtime. To workaround this issue, we force class initialization
phase to run with only one thread. Note this is only done when generating image
so application compilation is not impacted. This issue will be addressed in a
separate CL.

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.

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..

Populate dex cache for sharpened calls.
We ensured the resolved method was in the dex cache, but for a sharpened call
this is abstract. Ensure that the concrete method is also resolved.
Limit the use of direct dex cache based dispatch to cases where we know how to
patch the dex cache.

Get PORTABLE + SMALL on x86.
Implemented the portable resolution trampoline and
the portable to interpreter bridge.
Also work on integrating SEA_IR in the PORTABLE+SMALL framework.
Refactor some naming and correct indenting.

Refactor java.lang.reflect implementation
Cherry-picked from commit ed41d5c44299ec5d44b8514f6e17f802f48094d1.
Move to ArtMethod/Field instead of AbstractMethod/Field and have
java.lang.reflect APIs delegate to ArtMethod/ArtField.
Bug: 10014286.

Entry point clean up.
Create set of entry points needed for image methods to avoid fix-up at load time:
- interpreter - bridge to interpreter, bridge to compiled code
- jni - dlsym lookup
- quick - resolution and bridge to interpreter
- portable - resolution and bridge to interpreter
Fix JNI work around to use JNI work around argument rewriting code that'd been
accidentally disabled.
Remove abstact method error stub, use interpreter bridge instead.
Consolidate trampoline (previously stub) generation in generic helper.
Simplify trampolines to jump directly into assembly code, keeps stack crawlable.
Dex: replace use of int with ThreadOffset for values that are thread offsets.
Tidy entry point routines between interpreter, jni, quick and portable.
