Split profile recording from jit compilation
We still use ProfileInfo objects to record profile information. That
gives us the flexibility to add the inline caches in the future and the
convenience of the already implemented GC.
If UseJIT is false and SaveProfilingInfo true, we will only record the
ProfileInfo and never launch compilation tasks.

Revert "Revert "Refactor HGraphBuilder and SsaBuilder to remove HLocals""
This patch merges the instruction-building phases from HGraphBuilder
and SsaBuilder into a single HInstructionBuilder class. As a result,
it is not necessary to generate HLocal, HLoadLocal and HStoreLocal
instructions any more, as the builder produces SSA form directly.
Saves 5-15% of arena-allocated memory (see bug for more data):
GMS 20.46MB => 19.26MB (-5.86%)
Maps 24.12MB => 21.47MB (-10.98%)

Optimizing: Fix codegens for MethodLoadKind::kDexCacheViaMethod.
Use the original method index instead of the target method
index because the target method may point to a different dex
file.
No regression test: this currently happens only if the
codegen uses the kDexCacheViaMethod as a fallback for
another load kind and we aim to avoid that fallback, so it
would be difficult to write a reliable regression test. We
could try and exploit current fallbacks for irreducible
loops on x86 and arm but those fallbacks will eventually
disappear anyway.

two dex instructions, long-to-int and in int-to-byte.

ART: Implement HSelect
This patch adds a new HIR instruction to Optimizing. HSelect returns
one of two inputs based on the outcome of a condition.
This is only initial implementation which:
- defines the new instruction,
- repurposes BooleanSimplifier to emit it,
- extends InstructionSimplifier to statically resolve it,
- updates existing code and tests accordingly.
Code generators currently emit fallback if/then/else code and will be
updated in follow-up CLs to use platform-specific conditional moves
when possible.

ART: Implement support for instruction inlining
Optimizing HIR contains 'non-materialized' instructions which are
emitted at their use sites rather than their defining sites. This
was not properly handled by the liveness analysis which did not
adjust the use positions of the inputs of such instructions.
Despite the analysis being incorrect, the current use cases never
produce incorrect code.
This patch generalizes the concept of inlined instructions and
updates liveness analysis to set the compute use positions correctly.

ART: Remove incorrect HFakeString optimization
Simplification of HFakeString assumes that it cannot be used until
String.<init> is called which is not true and causes different
behaviour between the compiler and the interpreter. This patch
removes the optimization together with the HFakeString instruction.
Instead, HNewInstance is generated and an empty String allocated
until it is replaced with the result of the StringFactory call. This
is consistent with the behaviour of the interpreter but is too
conservative. A follow-up CL will attempt to optimize out the initial
allocation when possible.

Reduce code size by sharing slow paths.
Rationale:
Sharing identical slow path code reduces code size.
Background:
Currently, slow paths with the same dex-pc, same physical register
spilling code, and identical stack maps are shared (making this
only useful for deopt slow paths). The newly introduced mechanism
is sufficiently general to allow future improvements by e.g.
allowing different dex-pc (by passing this to runtime) or even
the kind of slow paths (by passing runtime addresses to the slowpath).

X86_64: Replace x86_64 xchg instruction use
Replacing 'xchg' to exchange two registers with a three instruction move
sequence using the 'TMP' register r10 seems to be a big win. This is
because xchg is a serializing instruction, even when used on registers.

Rewrite HInstruction::Is/As<type>().
Make Is<type>() and As<type>() non-virtual for concrete
instruction types, relying on GetKind(), and mark GetKind()
as PURE to improve optimization opportunities. This reduces
the number of relocations in libart-compiler.so's .rel.dyn
section by ~4K, or ~44%, and in .data.rel.ro by ~18K, or
~65%. The file is 96KiB smaller for Nexus 5, including 8KiB
reduction of the .text section.
Unfortunately, the g++/clang++ __attribute__((pure)) is not
strong enough to avoid duplicated virtual calls and we would
need the C++ [[pure]] attribute proposed in n3744 instead.
To work around this deficiency, we introduce an extra
non-virtual indirection for GetKind(), so that the compiler
can optimize common expressions such as
instruction->IsAdd() || instruction->IsSub()
or
instruction->IsAdd() && instruction->AsAdd()->...
which contain two virtual calls to GetKind() after inlining.

X86: Use locked add rather than mfence
Java semantics for memory ordering can be satisfied using
lock addl $0,0(SP)
rather than mfence. The locked add synchronizes the memory caches, but
doesn't affect device memory.
Timing on a micro benchmark with a mfence or lock add $0,0(sp) in a loop
with 600000000 iterations:
time ./mfence
real 0m5.411s
user 0m5.408s
sys 0m0.000s
time ./locked_add
real 0m3.552s
user 0m3.550s
sys 0m0.000s
Implement this as an instruction-set-feature lock_add. This is off by
default (uses mfence), and enabled for atom & silvermont variants.
Generation of mfence can be forced by a parameter to MemoryFence.

x86-64 Baker's read barrier fast path implementation.
Introduce an x86-64 fast path implementation in Optimizing
for Baker's read barriers (for both heap reference loads and
GC root loads). The marking phase of the read barrier is
performed by a slow path, invoking the runtime entry point
artReadBarrierMark.
Other read barrier algorithms continue to use the original
slow path based implementation, which has been renamed as
GenerateReadBarrierSlow/GenerateReadBarrierForRootSlow.

x86/x86-64 read barrier support for concurrent GC in Optimizing.
This first implementation uses slow paths to instrument heap
reference loads and GC root loads for the concurrent copying
collector, respectively calling the artReadBarrierSlow and
artReadBarrierForRootSlow (new) runtime entry points.
Notes:
- This implementation does not instrument HInvokeVirtual
nor HInvokeInterface instructions (for class reference
loads), as the corresponding read barriers are not stricly
required with the current concurrent copying collector.
- Intrinsics which may eventually call (on slow path) are
disabled when read barriers are enabled, as the current
slow path infrastructure does not support this case.
- When read barriers are enabled, the code generated for a
HArraySet instruction always go into the array set slow
path for object arrays (delegating the operation to the
runtime), as we are lacking a mechanism to keep a
temporary register live accross a runtime call (needed for
the instrumentation of type checking code, which requires
two successive read barriers).

Determine the dispatch type of invoke-static/-direct in a

It also allows the code generator to avoid requesting a
register location for the ArtMethod* for kDexCachePcRelative
and direct methods.
The supported dispatch check handles also situations that
the CompilerDriver currently doesn't allow. The cleanup of
the CompilerDriver and required changes to Quick will come
in a separate change.

Optimizing: Tag arena allocations in code generators.
And completely remove the deprecated GrowableArray.
Replace GrowableArray with ArenaVector in code generators
and related classes and tag arena allocations.
Label arrays use direct allocations from ArenaAllocator
because Label is non-copyable and non-movable and as such
cannot be really held in a container. The GrowableArray
never actually constructed them, instead relying on the
zero-initialized storage from the arena allocator to be
correct. We now actually construct the labels.
Also avoid StackMapStream::ComputeDexRegisterMapSize() being
passed null references, even though unused.

ART: Register allocation and runtime support for try/catch
This patch completes a series of CLs that add support for try/catch
in the Optimizing compiler. With it, Optimizing can compile all
methods containing try/catch, provided they don't contain catch loops.
Future work will focus on improving performance of the generated code.
SsaLivenessAnalysis was updated to propagate liveness information of
instructions live at catch blocks, and to keep location information on
instructions which may be caught by catch phis.
RegisterAllocator was extended to spill values used after catch, and
to allocate spill slots for catch phis. Catch phis generated for the
same vreg share a spill slot as the raw value must be the same.
Location builders and slow paths were updated to reflect the fact that
throwing an exception may not lead to escaping the method.
Instruction code generators are forbidden from using of implicit null
checks in try blocks as live registers need to be saved before handing
over to the runtime.
CodeGenerator emits a stack map for each catch block, storing locations
of catch phis. CodeInfo and StackMapStream recognize this new type of
stack map and store them separate from other stack maps to avoid dex_pc
conflicts.
After having found the target catch block to deliver an exception to,
QuickExceptionHandler looks up the dex register maps at the throwing
instruction and the catch block and copies the values over to their
respective locations.
The runtime-support approach was selected because it allows for the
best performance in the normal control-flow path, since no propagation
of catch phi values is necessary until the exception is thrown. In
addition, it also greatly simplifies the register allocation phase.
ConstantHoisting was removed from LICMTest because it instantiated
(now abstract) HConstant and was bogus anyway (constants are always in
the entry block).

SlowPath: Remove the use of Locations in the SlowPath constructors.
The main motivation is that using locations in the SlowPath constructors
ties us to creating the SlowPaths after register allocation, since before
the locations are invalid.
A later patch of the series will be moving the SlowPath creation to the
LocationsBuilder visitors. This will enable us to add more checking as
well as consider sharing multiple SlowPaths of the same type.

X86: Use short forward jumps if possible
The optimizing compiler uses 32 bit relative jumps for all forward
jumps, just in case the offset is too large to fit in one byte. Some of
the generated code knows that the jumps will in fact fit.
Use the 'NearLabel' class for the code generator and intrinsics.
Use the jecxz/jrcxz instruction for string intrinsics.
Unfortunately, conditional jumps to basic blocks don't know enough to
use this, as we don't know how much code will be generated.
This saves a whopping 0.24% for core.oat and boot.oat sizes, but
every little bit helps, and it reduces icache footprint slightly.

ART-Optimizing: Fix the type of HDivZeroCheck
HDivZeroCheck is created during the building CFG and at this moment
its type is not known completely. So it sets the type to int or long.
However, later SSA builder can insert the type conversion and type
of input of HDivZeroCheck can become byte or short while the type
of HDivZeroCheck remains the same.
In reality the type of HDivZeroCheck should be always equal to
its input parameter.
To fix this inconsistency we return the type of HDivZeroCheck as its
input type. Code generators are updated accordingly.

ART: Move exception clearing into own instruction
Runtime delivers exceptions only to catch blocks which begin with a
MOVE_EXCEPTION instruction (in DEX). In that case, the catch block is
expected to clear the thread-local exception storage after having
read the exception reference.
This patch changes Optimizing to represent MOVE_EXCEPTION with two
instructions - HLoadException and HClearException - instead of one.
If the exception reference is not used, HLoadException can be safely
removed, saving a memory load without breaking the runtime behaviour.

Note that the RHS operand must be a 32 bit constant, and that it is
possible for the constant to end up in a register (!) due to a previous
use by another instruction. Handle this case by checking the operand,
otherwise the first input might not be the same as the output, due to
the use of Any().
Also allow stack operands for multiplication.

Revert "Revert "ART: Implement try/catch blocks in Builder""
This patch enables the GraphBuilder to generate blocks and edges which
represent the exceptional control flow when try/catch blocks are
present in the code. Actual compilation is still delegated to Quick
and Baseline ignores the additional code.
To represent the relationship between try and catch blocks, Builder
splits the edges which enter/exit a try block and links the newly
created blocks to the corresponding exception handlers. This layout
will later enable the SsaBuilder to correctly infer the dominators of
the catch blocks and to produce the appropriate reverse post ordering.
It will not, however, allow for building the complete SSA form of the
catch blocks and consequently optimizing such blocks.
To this end, a new TryBoundary control-flow instruction is introduced.
Codegen treats it the same as a Goto but it allows for additional
successors (the handlers).
This reverts commit 3e18738bd338e9f8363b26bc895f38c0ec682824.

Ensure inlined static calls perform clinit checks in Optimizing.
Calls to static methods have implicit class initialization
(clinit) checks of the method's declaring class in
Optimizing. However, when such a static call is inlined,
the implicit clinit check vanishes, possibly leading to an
incorrect behavior.
To ensure that inlining static methods does not change the
behavior of a program, add explicit class initialization
checks (art::HClinitCheck) as well as load class
instructions (art::HLoadClass) as last input of static
calls (art::HInvokeStaticOrDirect) in Optimizing' control
flow graphs, when the declaring class is reachable and not
known to be already initialized. Then when considering the
inlining of a static method call, proceed only if the method
has no implicit clinit check requirement.
The added explicit clinit checks are already removed by the
art::PrepareForRegisterAllocation visitor. This CL also
extends this visitor to turn explicit clinit checks from
static invokes into implicit ones after the inlining step,
by removing the added art::HLoadClass nodes mentioned
hereinbefore.

Remove ArtMethod* parameter from dex cache entry points.
Load the ArtMethod* using an optimized stack walk instead.
This reduces the size of the generated code.
Three of the entry points are called only from a slow-path
and the fourth (InitializeTypeAndVerifyAccess) is rare and
already slow enough that the one or two extra loads
(depending on whether we already have the ArtMethod* in a
register) are insignificant. And as we're starting to use
PC-relative addressing of the dex cache arrays (already
done by Quick for the boot image), having the ArtMethod* in
a register becomes less likely anyway.

Optimizations simplifying operations on boolean values (boolean

This patch implements HBooleanNot as 'x xor 1', assuming that booleans
are 1-bit integers and allowing for a single-instruction negation on
all supported platforms.

[optimizing] Improve x86 parallel moves/swaps
Add a new constructor to ScratchRegisterScope that will supply a
register if there is a free one, but not spill to force one. Use this
to generated alternate code that doesn't use a temporary, as the
spill/restore of a register generates extra instructions that aren't
necessary on x86.
Here is the benefit for a 32 bit memory-to-memory exchange with no
free registers:
< 50 push eax
< 53 push ebx
< 8B44244C mov eax, [esp + 76]
< 8B5C246C mov ebx, [esp + 108]
< 8944246C mov [esp + 108], eax
< 895C244C mov [esp + 76], ebx
< 5B pop ebx
< 58 pop eax
---
> FF742444 push [esp + 68]
> FF742468 push [esp + 104]
> 8F44244C pop [esp + 72]
> 8F442468 pop [esp + 100]
Avoid using xchg instruction, as it is slow on smaller processors.

ART: Boolean simplifier
The optimization recognizes the negation pattern generated by 'javac'
and replaces it with a single condition. To this end, boolean values
are now consistently assumed to be represented by an integer.
This is a first optimization which deletes blocks from the HGraph and
does so by replacing the corresponding entries with null. Hence,
existing code can continue indexing the list of blocks with the block
ID, but must check for null when iterating over the list.

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'.

Deoptimization-based bce.
A mechanism is introduced that a runtime method can be called
from code compiled with optimizing compiler to deoptimize into
interpreter. This can be used to establish invariants in the managed code
If the invariant does not hold at runtime, we will deoptimize and continue
execution in the interpreter. This allows to optimize the managed code as
if the invariant was proven during compile time. However, the exception
will be thrown according to the semantics demanded by the spec.
The invariant and optimization included in this patch are based on the
length of an array. Given a set of array accesses with constant indices
{c1, ..., cn}, we can optimize away all bounds checks iff all 0 <= min(ci) and
max(ci) < array-length. The first can be proven statically. The second can be
established with a deoptimization-based invariant. This replaces n bounds
checks with one invariant check (plus slow-path code).

[optimizing compiler] x86 goodness
Implement the x86 version of
https://android-review.googlesource.com/#/c/129560/, which made some
enhancements to x86_64 code.
- Use leal to implement 3 operand adds
- Use testl rather than cmpl to 0 for registers
- Use leaq for x86_64 for adds with constant in int32_t range
Note:
- The range and register allocator tests seem quite fragile. I had to
change ADD_INT_LIT8 to XOR_INT_LIT8 for the register allocator test to
get the code to run. It seems like this is a bit hard-coded to
expected code generation sequences. I also changes BuildTwoAdds to
BuildTwoSubs for the same reason.
- For the live range test, I just changed the expected output, as the
Locations were different.

ImplicitNullChecks are recorded only for instructions directly (see NB
below) preceeded by NullChecks in the graph. This way we avoid recording
redundant safepoints and minimize the code size increase.
NB: ParallalelMoves might be inserted by the register allocator between
the NullChecks and their uses. These modify the environment and the
correct action would be to reverse their modification. This will be
addressed in a follow-up CL.

Don't block quick callee saved registers for optimizing.
This change builds on:
https://android-review.googlesource.com/#/c/118983/
- Also fix x86_64 assembler bug triggered by this change.
- Fix (and improve) x86's backend byte register usage.
- Fix a bug in baseline register allocator: a fixed
out register must prevent inputs from allocating it.

Fix a bug in the type analysis phase of optimizing.
Dex code can lead to the creation of a phi with one
float input and one integer input. Since the SSA builder trusts
the verifier, it assumes that the integer input must be converted
to float. However, when the register is not used afterwards, the
verifier hasn't ensured that. Therefore, the compiler must remove
the phi prior to doing type propagation.

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.

Implement int bit-wise not operation in the optimizing compiler.
- Add support for the not-int (integer one's complement
negate) instruction in the optimizing compiler.
- Extend the HNot control-flow graph node type and make it
inherit from HUnaryOperation.
- Generate ARM, x86 and x86-64 code for integer HNeg nodes.
- Exercise these additions in the codegen_test gtest, as there
is not direct way to assess the support of not-int from a
Java source. Indeed, compiling a Java expression such as
`~a' using javac and then dx generates an xor-int/lit8 Dex
instruction instead of the expected not-int Dex instruction.
This is probably because the Java bytecode has an `ixor'
instruction, but there's not instruction directly
corresponding to a bit-wise not operation.

Remove the notion of dies at entry.
- Instead, explicitly say that the output does not overlap.
- Inputs that must be in a fixed register do die at entry,
as we know they have a location that others can not take.
- There is also no need to differentiate between an input move
and a connecting sibling move - those can be put in the
same parallel move instruction.

Implement suspend checks in new compiler.
For simplicity, they are currently placed on all (dex-level)
back edges, and at method entry.

Runtime support for the new stack maps for the opt compiler.
Now most of the methods supported by the compiler can be optimized,
instead of using the baseline.

Reduce stack usage for overflow checks
This reduces the stack space reserved for overflow checks to 12K, split
into an 8K gap and a 4K protected region. GC needs over 8K when running
in a stack overflow situation.
Also prevents signal runaway by detecting a signal inside code that
resulted from a signal handler invokation. And adds a max signal count to
the SignalTest to prevent it running forever.
Also reduces the number of iterations for the InterfaceTest as this was
taking (almost) forever with the --trace option on run-test.

Support fields in optimizing compiler.
- Required support for temporaries, to be only used by baseline compiler.
- Also fixed a few invalid assumptions around locations and instructions
that don't need materialization. These instructions should not have an Out.

Add some more instruction support to optimizing compiler.
This adds a few more DEX instructions to the optimizing compiler's
builder (constants, moves, if_xx, etc).
Also:
* Changes the codegen for IF_XX instructions to use a condition
rather than comparing a value against 0.
* Fixes some instructions in the ARM disassembler.
* Fixes PushList and PopList in the thumb2 assembler.
* Switches the assembler for the optimizing compiler to thumb2
rather than ARM.
