This CL implements an AST walk for the analysis and plugs the result into the TurboFan graph builder. I left this analysis under a flag for A/B testing and until sufficient unit tests can be developed.

Revert "RegExp: Add support for the ES6-proposed sticky flag"
...
Causes a flaky failure on buildbots. Here is the (deterministic) repro step (thanks to Michael Stanton):
first go to flag-definitions.h and set this to false.
DEFINE_BOOL(enable_sse4_1, false,
"enable use of SSE4.1 instructions if available")
Run the following and it should fail:

Some fixes to avoid breakages when enabling out-of-line constant pools.
...
Three fixes which are required to pass all the tests when out-of-line constant
pools are enabled for Arm:
- Invalidate embedded objects in optimized code when it is deoptimized such
that the weak pointers in the constant pool array are cleared. This prevents
a CHECK(heap_->mark_compact_collector()->IsMarked(object)) error when a
verifying weak pointers in a deoptimized code object's constant pool.
- Modify LargeObjectSpace::Verify to allow constant pool arrays in the
large object space.
- Increase the 32bit stack size limit, since the constant pool pointer
is now on every stack frame, causing the size of each stack frame to
increase by one word, and causing deep-recursion-test to fail.

Implement handling of arrow functions in the parser
...
Arrow functions are parsed from ParseAssignmentExpression(). Handling the
parameter list is done by letting ParseConditionalExpression() parse a comma
separated list of identifiers, and it returns a tree of BinaryOperation nodes
with VariableProxy leaves, or a single VariableProxy if there is only one
parameter. When the arrow token "=>" is found, the VariableProxy nodes are
passed to ParseArrowFunctionLiteral(), which will then skip parsing the
paramaeter list. This avoids having to rewind when the arrow is found and
restart parsing the parameter list.
Note that the empty parameter list "()" is handled directly in
ParsePrimaryExpression(): after is has consumed the opening parenthesis,
if a closing parenthesis follows, then the only valid input is an arrow
function. In this case, ParsePrimaryExpression() directly calls
ParseArrowFunctionLiteral(), to avoid needing to return a sentinel value
to signal the empty parameter list. Because it will consume the body of
the arrow function, ParseAssignmentExpression() will not see the arrow
"=>" token as next, and return the already-parser expression.
The implementation is done in ParserBase, so it was needed to do some
additions to ParserBase, ParserTraits and PreParserTraits. Some of the
glue code can be removed later on when more more functionality is moved
to ParserBase.
Additionally, this adds a runtime flag "harmony_arrow_functions"
(disabled by default); enabling "harmony" will enable it as well.

Implement handling of arrow functions in the parser

Arrow functions are parsed from ParseAssignmentExpression. Handling the
parameter list is done by letting ParseConditionalExpression() parse
a comma-separated list of identifiers, and it returns a tree of
BinaryOperation nodes with VariableProxy leaves, or a single
VariableProxy if there is only one parameter. When the arrow token "=>"
is found, the VariableProxy nodes are passed to ParseFunctionLiteral(),
which will then skip parsing the paramaeter list. This avoids having
to rewind when the arrow is found and restart parsing the parameter
list. Note that ParseExpression() expects parenthesized expressions
to not be empty, so checking for a closing parenthesis is added in
handling the empty parameter list "()" will accept a right-paren and
return an empty expression, which means that the parameter list is
empty.
Additionally, this adds the following machinery:
- A runtime flag "harmony_arrow_functions" (disabled by default).
Enabling "harmony" will enable it as well.
- An IsArrow bit in SharedFunctionInfo, and accessors for it.
- An IsArrow bit in FunctionLiteral, accessorts for it, and
a constructor parameter to set its value.
- In ParserBase: allow_arrow_functions() and set_allow_arrow_functions()
- A V8 native %FunctionIsArrow(), which is used to skip adding the
"function " prefix when getting the source code for an arrow
function.

make simulator / native more consistent
- Unify CpuFeatures::PrintTarget for simulator and native builds
- Remove unecessary CAN_USE_VFP_INSTRUCTIONS definition for android (this is
the default for arm_fpu=default)
- Add a CpuFeatures::Probe() before calling CpuFeatures::PrintFeatures() in PrintHelp
to ensure we have probed features before printing them.

Support external startup data in V8.
...
If the embedder chooses, the 'natives' (library sources) and the
precompiled startup blob can be written to files during the build
process and handed over to V8 at startup. The main purpose would be
to reduce the size of the compiled binary for space constrained
platforms.
The build-time option is off by default. Nothing should change if
it's not enabled.

Arm64: Ensure that csp is always aligned to 16 byte values even if jssp is not.
...
Even although the Arm64 specification specifies that csp
only needs to be aligned to 16 bytes if it is dereferenced, some implementations show poor performance if csp is every set to a non-aligned value. This CL ensures that csp is always aligned to 16 byte values on these platforms and adds checks to ensure this in debug mode.
Also makes the following change:
- Enable CPU support for arm64 to enable probing of cpu implementer and cpu part.
- Add ALWAYS_ALIGN_CSP CpuFeature for Arm64 and set it based on runtime probing of the cpu implementer.
- Rename PrepareForPush and PrepareForPop to PushPreamble and PopPostamble and move PopPostable after the pop.

Improve positions tracking inside the HGraphBuilder.
...
Instead of tracking simple absolute offset from the start of the script like other places do, track a pair of (inlining id, offset from the start of inlined function).
This enables us to pinpoint with inlining path an instruction came from. Previously in multi-script environments we emitted positions that made very little sense because inside a single optimized function they would point to different scripts without a way to distinguish them.
Start dumping the source of every inlined function to make possible IR viewing tools with integrated source views as there was previously no way to acquire this information from IR dumps. We also dump source position at which each inlining occured.
Tracked positions are written into hydrogen.cfg as pos:<inlining-id>_<offset>.
Flag --emit-opt-code-positions is renamed by this change into --hydrogen-track-positions to better convey it's meaning.
In addition this change assigned global unique identifier to each optimization performed inside isolate. This allows to precisely match compilation artifacts (e.g. IR and disassembly) and deoptimizations.

Harmony promises
...
Based on prototype at
https://github.com/rossberg-chromium/js-promise
which informed the latest spec draft version at
https://github.com/domenic/promises-unwrapping/blob/master/README.md
Activated by --harmony-promises.
Feature complete with respect to the draft spec, plus the addition of .when and .deferred methods. Final naming and other possible deviations from the current draft will hopefully be resolved soon after the next TC39 meeting.
This CL also generalises the Object.observe delivery loop into a simplistic microtask loop. Currently, all observer events are delivered before invoking any promise handler in a single fixpoint iteration. It's not clear yet what the final semantics is supposed to be (should there be a global event ordering?), but it will probably require a more thorough event loop abstraction inside V8 once we get there.

Support for the Linux 'perf report' and 'perf annotate' tools.
...
In this change, the support comes in two flavours:
--perf_jit_prof - outputs the files in a new perf format that only works with a
patched perf tool (patch obtained from Stephane Eranian). Both 'perf report' and
'perf annotate' are supported (the file format also contains the machine code).
--perf_basic_prof - outputs the files in a format that the existing perf tool
can consume. Only 'perf report' is supported.
In both cases, we have to disable code compaction because the perf tool does not
understand code relocation. (We are told that code relocation should be
supported soon.)
Usage:
perf record -g d8 --perf_jit_prof --no_compact_code_space my.js
perf report
The change itself is straightforward - we simply listen to code events and
write an entry to a log file for every new piece of code.
I am not yet sure whether we should keep both versions or just one (and which
one). My hope is the reviewers can help here.

This mangling scheme matches hydrogen.cfg and allows easy discovery of compilation artifacts in a multi-V8 environment (e.g. when compilation is traced from inside Chromium).
D8 defines --redirect_code_traces_to=code.asm similar to hydrogen.cfg redirection.

Remove deprecated profiler API
...
This change removes --prof-lazy command line flag that was introduced for the old CPU profiler implementation in Chrome DevTools. DevTools now use profiler API defined in v8-profiler.h
This change also removes methods for pausing resuming --prof profiler. These methods were deprecated in v.3.20 (https://code.google.com/p/v8/source/browse/branches/3.20/include/v8.h#4629 )
After this change the profiler will always start if --prof option is passed and can be stopped either in the tests or if write to log file fails.

Support higher CPU profiler sampling rate on posix systems
...
New flag is added that allows to specify CPU profiler sampling rate in microseconds as command line argument. It was tested to work fine with 100us interval(currently it is 1ms). Default values are kept the same as in the current implementation. The new implementation is enabled only on POSIX platforms which use signals to collect samples. Other platforms that pause thread being sampled are to follow.
SIGPROF signals are now sent on the profiler event processor thread to make sure that the processing thread does fall far behind the sampling.
The patch is based on the previous one that was rolled out in r13851. The main difference is that the circular queue is not modified for now.
On Linux sampling for CPU profiler is initiated on the profiler event processor thread, other platforms to follow.
CPU profiler continues to use SamplingCircularQueue, we will probably replace it with a single sample buffer when Mac and Win ports support profiling on the event processing thread.
When --prof option is specified profiling is initiated either on the profiler event processor thread if CPU profiler is on or on the SignalSender thread as it used to be if no CPU profiles are being collected.
ProfilerEventsProcessor::ProcessEventsAndDoSample now waits in a tight loop, processing collected samples until sampling interval expires. To save CPU resources I'm planning to change that to use nanosleep as only one sample is expected in the queue at any point.

Add --trace-hydrogen-filter flag.
...
The flag restricts hydrogen.cfg output to functions passing the filter,
similar to what --hydrogen-filter does for optimization in general.
This is useful for investigating large repro cases where tracing all
functions would lead to an impractically large hydrogen.cfg file, but
restricting optimization using --hydrogen-filter is undesirable
(e.g. because it might cause the issue to no longer reproduce).

Reland deprecation of HAllocateObject in favor of HAllocate.
...
This essentially relands r14930 and r14935 with adaptions to the current
code base. It models the instantiation of an implicit receiver for
CallNew nodes in hydrogen using HAllocate together with generic stores
instead of one specialized HAllocateObject instruction, hence creating a
single choking point for inlined allocation in optimized code.

ARM: Makefile/gyp update allowing better control of ARM specific options.
...
This patch defines new makefile command line paramaters to better control the
ARM specific options. The new paramters are
* armfpu = vfp, vfpv3-d16, vfpv3, neon.
* armfloatabi = softfp, hard
* armneon = on
* armthumb = on, off
* armtest = on
One existing paratemer has been modified:
* armv7 = true, false
A number of parameters have been deprecated (but are still working):
* hardfp = on, off
* vfp2 = off
* vfp3 = off
the armtest paratmer when set to "on" will lock the options used during compile
time at runtime. This allows for example to easily test the ARMv6 build on an
ARMv7 platform without having to worry about features detected at runtime. When
not specified the compiler default will be used meaning it is not necessary
anymore to specify hardfp=on when natively building on an hardfp platform.
The shell help now prints the target options and features detected.

Add parser support for generators.
...
This patchset begins by adding support for "yield", which is unlike other tokens
in JS. In a generator, whether strict or classic, it is a syntactic keyword.
In classic mode it is an identifier. In strict mode it is reserved.
This patch adds YIELD as a token to the scanner, and adapts the preparser and
parser appropriately. It also parses "function*", indicating that a function is
actually a generator, for both eagerly and lazily parsed functions.
Currently "yield" just compiles as "return".

ES6 symbols: Implement Symbol intrinsic and basic functionality
...
- Add --harmony-symbols flag.
- Add Symbol constructor; allow symbols as (unreplaced) return value from constructors.
- Introduce %CreateSymbol and %_IsSymbol natives and respective instructions.
- Extend 'typeof' code generation to handle symbols.
- Extend CompareIC with a UNIQUE_NAMES state that (uniformly) handles internalized strings and symbols.
- Property lookup delegates to SymbolDelegate object for symbols, which only carries the toString method.
- Extend Object.prototype.toString to recognise symbols.
Per the current draft spec, symbols are actually pseudo objects that are frozen with a null prototype and only one property (toString). For simplicity, we do not treat them as proper objects for now, although typeof will return "object". Only property access works as if they were (frozen) objects (via the internal delegate object).

Send SIGPROF signals on the profiler event processor thread
...
The patch is based on the previous one that was rolled out: https://code.google.com/p/v8/source/detail?r=12985
On Linux sampling for CPU profiler is initiated on the profiler event processor thread, other platforms to follow.
CPU profiler continues to use SamplingCircularQueue, we will replave it with a single sample buffer when Mac and Win ports support profiling on the event processing thread.
When --prof option is specified profiling is initiated either on the profiler event processor thread if CPU profiler is on or on the SignalSender thread as it used to if no CPU profiles are being collected.
ProfilerEventsProcessor::ProcessEventsAndDoSample now waits in a tight loop, processing collected samples until sampling interval expires. To save CPU resources I'm planning to change that to use nanosleep as only one sample is expected in the queue at any point.

Adapt Danno's Track Allocation Info idea to fast literals. When allocating a literal array,
...
we store an AllocationSiteInfo object right after the JSArray, with a pointer to the
boilerplate object. Later, if the array transitions we check for the continued existence
of the temporary AllocationSiteInfo object (has no roots). If found, we'll use it to
transition the boilerplate array as well.

Add code again to allow reclaiming old unexecuted functions.

When code objects in the heap for FUNCTIONs and OPTIMIZED_FUNCTIONs are marked by the GC, their prologue is patched with a call to a stub that removes the patch. This allows the collector to quickly identify code objects that haven't been executed since the last full collection (they are the ones that sill contain the patch). The functionality is currently disabled, but can be activated by specifying the "--age-code".

Added a simple dead code removal phase.
...
We iteratively remove all dead Hydrogen instruction until we reach a fixed point. We consider an instruction dead if it is unused, has no observable side effects and is deletable. The last part of the condition is currently not very nice: We basically have to whitelist "safe" instructions, because we are missing more detailed dependencies and/or more detailed tracking of side effects.
We disable dead code elimination for now in our test runners, because we have tons of poorly written tests which wouldn't test anymore what they are supposed to test with this phase enabled. To get test coverage for dead code elimination itself, we should enable it on a few build bots. This is not really a perfect state, but the best we can do for now.
This patch includes a few const-correctness fixes, most of them were necessary for this CL.

Deoptimization support for accessors.
...
Highlights of this CL:
* Introduced a new opcode in the deoptimizer for a setter stub frame.
* Added a global setter stub for returning after deoptimizing a setter.
* We do not need special deopt support for getters, although the getter stub creates an internal frame. The normal machinery works just right for this case, although we generate a stack that can never occur during normal fullcode execution.

This adds the --verify-global-context-separation flag which can be used
to verify that no code object embeds pointers to more than one global
context after a full GC. It uses an object visitor that just performs
shallow traversal of the object graph spanned by one code object, and
breaks at points where application objects are encountered. So it will
not trip on cross-context leaks introduced by the application itself.

Re-land: Use map transitions when defining accessor properties.

This is basically r11496, with the following changes:
* Set back pointers in maps (cherry-picked from r11528)
* Fixed size calculation in CopyInsert, as proposed by mstarzinger/rossberg
* DefineFastAccessor uses GetCallbackObject instead of GetValue (for __proto__)
* Put the code under a new flag, which is disabled by default
* Cut down the corresponding regression test
* Adapted bootup memory test, we actually only need a bit more memory on 64bit without snapshots, which can easily explained by more live maps lying around. Note that the snapshot variants are back to their previous limits.
Next steps: Investigate any performance degradationswith the flag enabled, and finally remove the flag when things are OK. Furthermore, GetCallbackObject should be merged into GetValue, the distinction is confusing and error-prone.

Array index computation dehoisting.

When an array index (in an array access) is a simple "expression + constant", just embed the constant in the array access operation so that the full index expression is (potentially) no longer used and its live range can be much shorter.
This is effective in conjunction with array bounds check removal (otherwise the index is anyway used in the check).

As a special case, for checks on index expressions with the form (expr + constant) if a smaller constant is checked later in the DT also eliminate the check.
Finally, if a larger constant is checked later in the same BB do the more general check (larger constant) earlier instead of the less general one.
This will not cause useless deoptimizations because, since we are in the same BB, all the checks would have been executed anyway.

Landing for pliard@chromium.org: Remove static initializers in v8.
...
This change includes two CLs by pliard@chromium.org:
1. http://codereview.chromium.org/9447052/ (Add CallOnce() and simple LazyInstance implementation):
Note that this implementation of LazyInstance does not handle global destructors (i.e. the lazy instances are never deleted).
This CL was initially reviewed on codereview.appspot.com:
http://codereview.appspot.com/5687064/
2. http://codereview.chromium.org/9455088/ (Remove static initializers in v8):
This CL depends on CL 9447052 (adding CallOnce and LazyInstance).
It is based on a patch sent by Digit.
With this patch applied, we have only one static initializer left (in atomicops_internals_x86_gcc.cc). This static initializer populates a structure used by x86 atomic operations. It seems that we can hardly remove it. If possible, it will be removed in a next CL.
This CL also modifies the presubmit script to check the number of static initializers.

Basic interface inference for modules.
...
All module expressions, and all variables that might refer to modules,
are assigned interfaces (module types) that are resolved using
unification. This is necessary to deal with the highly recursive
nature of ES6 modules, which does not allow any kind of bottom-up
strategy for resolving module names and paths.
Error messages are rudimental right now. Probably need to track
more information to make them nicer.

Make built-ins strict mode conforming, and support a --use-strict flag.
...
* Turned all uses of 'const' into 'var'.
* Turned all uses of local 'function' into 'var'.
* Added a couple of missing toplevel 'var' declarations.
One consequence is that the properties on the builtin object are no longer
non-writable, and I had to adapt one test. Is that a problem?
Unfortunately, we cannot actually switch the library scripts to strict mode
by default, because that makes observable things like poisoned .caller properties
for library functions.
Also removed dead flag code in Compiler::Compile.

Allow bailing out of the register allocator when running out of virtual registers.
...
1. Instead of checking upfront and estimating a limit for the number, we
now are able to stop register allocation and bailout when we don't
have enough virtual registers.
2. GCed some out-dated flags from flag-definition.h
3. Simplified the interface from the Lithium builder to the
register allocator in lithium-*.cc: For uses and definitions, we
just record the virtual register number given by the Hydrogen value id.
For temporaries, we request a new virtual register from the allocator.
For fixed temps, we don't need to do anything.
4. Increased number of deoptimization entries to 16K. Eventually we
probably want to make this array grow dynamically.

Randomize the seed used for string hashing. This helps guard against
...
CPU-eating DOS attacks against node.js servers. Based on code from
Bert Belder. This version only solves the issue for those that compile
V8 themselves or those that do not use snapshots. A snapshot-based
precompiled V8 will still have predictable string hash codes.

Introduce extended mode.
...
This CL introduces a third mode next to the non-strict
(henceforth called 'classic mode') and 'strict mode'
which is called 'extended mode' as in the current
ES.next specification drafts. The extended mode is based on
the 'strict mode' and adds new functionality to it. This
means that most of the semantics of these two modes
coincide.
The 'extended mode' is entered instead of the 'strict mode'
during parsing when using the 'strict mode' directive
"use strict" and when the the harmony-scoping flag is
active. This should be changed once it is fully specified how the 'extended mode' is entered.
This change introduces a new 3 valued enum LanguageMode
(see globals.h) corresponding to the modes which is mostly
used by the frontend code. This includes the following
components:
* (Pre)Parser
* Compiler
* SharedFunctionInfo, Scope and ScopeInfo
* runtime functions: StoreContextSlot,
ResolvePossiblyDirectEval, InitializeVarGlobal,
DeclareGlobals
The old enum StrictModeFlag is still used in the backend
when the distinction between the 'strict mode' and the 'extended mode' does not matter. This includes:
* SetProperty runtime function, Delete builtin
* StoreIC and KeyedStoreIC
* StubCache
