MIPS: Fix DIRECT_API_CALL_NEW and DIRECT_GETTER_CALL_NEW call.
...
This commit fixes the register usage of DIRECT_API_CALL_NEW
and DIRECT_GETTER_CALL_NEW:
* These functions expect arguments in a0-a1 and not in a1-a2
as the and DIRECT_API_CALL and DIRECT_GETTER_CALL do.
* Fixes the simulator to expect *_NEW arguments in a0-a1.
* Adds more comment to simulator to better explain the
register usage.

fix some names in compare nil ic

The compare nil ic introduces a mechanism called lightweight miss. The
idea is to insert a direct call to the miss handler instead of going
through the deopt routine. This can be use for uninitialized stubs, to
directly jump to the runtime.
This cl
1. Cleans up naming
2. localizes the lightweight miss functionality on the only user (compare nil ic)
3. fixes DoCodegen, to actually call the correct method (uninitialized vs initialized)

Make Object.freeze fast
...
This patch both speeds up the freeze operation itself, but also
allows properties to remain in fast mode. Objects with non-empty
elements backing stores still end up with slow elements.
Relanding r14758 and r14759 with fix for Test262: only mark properties
and elements READ_ONLY if they are not JS setter/getters. Tightened up
tests to assert frozen-ness, and added targeted tests for the new code
(covering accessors).

Fix Object.freeze on dictionary-backed arrays to properly freeze elements
...
Follow-up to r14758: slightly rearranges JSObject::Freeze() to avoid duplicating
code while still retaining proper dictionary elements storage behavior.
Also fix a lint error.

This patch both speeds up the freeze operation itself, but also
allows properties to remain in fast mode. Objects with non-empty

Refactoring:
* consistent use of SmiTag/Untag
* added a few Smi macros and helpers
Improvements
* small optimisations (e.g. merging untag and cmp #0 )
* added fixed point to double conversion instructions for simpler conversions
More on the last point: a Smi can be seen as a fixed point number with the
a one bit fractional part. Fixed to double instructions allow us to convert
a Smi to a double without untagging.

MIPS: Implement yield* (delegating yield)
...
Port r14669 (b64ce42a)
Original commit message:
Ideally this would have been implemented via desugaring at parse-time,
but yield* is an expression, and its desugaring includes statements like
while and try/catch. We'd have to have BlockExpression in the AST to
support that, and it's not worth it for this feature.
So instead we implement all of the logic in
FullCodeGenerator::VisitYield. Delegating yield AST nodes now have a
try handler index, for the try/catch. Otherwise the implementation is
straightforward.

behavior. It also fills in a piece of the implementation where
otherwise calling GeneratorFunction or GeneratorFunctionPrototype would

Skip samples where top function's stack frame is not setup properly
...
Stack iterator takes return address based on the frame pointer (ebp) and detects JS frames based on value at fp + StandardFrameConstants::kMarkerOffset. So in order the iterator to work correctly this values should be already setup for the current function. Stack frame is constructed at the very beginning of JS function code and destroyed before return. If sample is taken before before the frame construction is completed or after it was destroyed the stack iterator will wrongly think that FP points at the current functions frame base and will skip callers frame. To avoid this we mark code ranges where stack frame doesn't exist and completely ignore such samples.
This fixes cctest/test-cpu-profiler/CollectCpuProfile flakiness.

Ideally this would have been implemented via desugaring at parse-time,
but yield* is an expression, and its desugaring includes statements like
while and try/catch. We'd have to have BlockExpression in the AST to
support that, and it's not worth it for this feature.
So instead we implement all of the logic in
FullCodeGenerator::VisitYield. Delegating yield AST nodes now have a
try handler index, for the try/catch. Otherwise the implementation is
straightforward.

Remove separate maps for function instances
...
ES3 specified that functions created via Function() would have
enumerable prototypes, unlike function literals. For this reason, V8
has always had two prototypes for functions: "function_map" for
literals, and "function_instance_map" for "function instances": those
functions created by Function().
However, since 2009 or so, both maps have been the same! Both have had
writable, non-enumerable prototypes. Moreover, ES5 changed to specify
that function instances would have non-enumerable prototypes.
This patch removes the separate maps for function instances in sloppy
and strict mode.

Add support for yield expressions
...
This CL extends the generator suspend and resume implementation to
capture values on the operand stack.
It factors out some helpers to measure and access the operand stack into
the JavaScriptFrame class. It also refactors the suspend and resume
helpers to avoid handle allocation.

Fix yield inside with
...
This patch makes it so that suspending generators always saves the
context. Previously we erroneously assumed that if the operand stack
was empty, that the context would be unchanged, but that is not the case
with "with".
Fixing this brought out an interesting bug in the variable allocator.
Yield inside with will reference a context-allocated temporary holding
the generator object. Before the fix, this object was looked up in the
with context instead of the function context, because with contexts were
not being simulated during full-codegen. Previously this was OK as all
variables would be given LOOKUP allocation instead of CONTEXT, but the
context-allocated temporary invalidated this assumption. The fix is to
simulate the context chain more accurately in full-codegen.

Do not emit double values at their use sites.
...
Revert part of r14179. From the regression test's comment:
Currently, the gap resolver doesn't handle moves from a ConstantOperand to a
DoubleRegister, but these kind of moves appeared when HConstant::EmitAtUses
was changed to allow special double values (-0, NaN, hole). So we should
either enhance the gap resolver or make sure that such moves don't happen.

Various improvements regarding the way we print code code comments.
...
* All Lithium instructions have an associated Hydrogen instruction now,
simplifying things.
* Consistently print <Lithium instruction number,Hydrogen value id> prefixes.
* Do not print uninteresting Lithium instructions like empty gaps, jumps to the
next instruction, etc.
* Removed special handling of HChange-like instructions, it is totally unclear
why they had this special treatment. If we really want to print more
information about Lithium instructions, we should do it in a totally way,
anyway (e.g. by unifying things with the generation of hydrogen*.cfg files).
* Made deferred code and the jump table stand out a little bit more.
* Print info about special blocks like loop headers and OSR entries.

This CL is split off another CL for easier reviewing.

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.

Fix bug introduced by r13960.

Allocator does not backtrack thus during allocation we must not create an unhandled live
range which starts before the start of the current live range.
If such range is added to the list of unhandled it might see an inconsistent state of active/inactive live-ranges as they are retired to handled as soon as start of the current live range is larger than their end.
Add assertion to catch this kind of bugs early.

This is a first step to having profiler sampler implementation in one file with platform capabilities guarded with #ifdef. Otherwise we have very similar implementations scattered over platform-*.cc files which makes it hard to see differences and make changes.
The next steps will be to merge win32, Mac OS X and Cygwin implementations into sampler.cc They suspend profiled thread instead of sending a signal but apart from that the logic is pretty much the same. Then I'm going to move sampler-related code from log.* into sampler.*

Fix detection of indexed properties in Object.defineProperty()

When defining an indexed property on an Array object, the object's
length property should (perhaps) be updated. This was done for any
property for which
ToUInt32(name) == ToNumber(name)
was true, meaning any property name that, when converted to a number,
was an integer in the range [0, 2^32). The detection should be more
strict; an indexed property is one for which
ToString(ToUInt32(name)) == name
is true only.

MIPS: Accurate function prototypes for native calls from ARM simulator.
...
Port r14230 (76c22097)
Original commit message:
Native method invocation from the arm/simulator-arm.cc previously made
non-portable assumptions about calling conventions. This was okay for 32-bit
stack-based machines, where by-value structs are automatically materialized
on the stack, and where both int and double parameters could be passed on the
stack. However they are not okay for x86-64, which has an elaborate scheme

Accurate function prototypes for native calls from ARM simulator.
...
Native method invocation from the arm/simulator-arm.cc previously made
non-portable assumptions about calling conventions. This was okay for 32-bit
stack-based machines, where by-value structs are automatically materialized
on the stack, and where both int and double parameters could be passed on the
stack. However they are not okay for x86-64, which has an elaborate scheme
for passing parameters in registers.
This CL replaces the previous non-portable code paths with portable code,
using call-sites that accurately match the prototype of the callee.

ES6 symbols: extend V8 API to support symbols

Specifically:
- Introduce Symbol and SymbolObject classes.
- Generalise Object::Has and Object::Delete to arbitrary Value-typed keys.
- Generalise some places in the API implementation from String to Name.
It is not possible to intercept symbol-named properties. That is consistent with the idea that symbols are private and should not leak.

Add sanity test for CPU profiler
...
The new test checks full CPU profiling cycle: using public
V8 API it starts profiling, executes a script, stops profiling
and analyzes collected profile to check that its top-down
tree has expected strutcture. The script that is being profiled
is guaranteed to run > 200ms to make sure enough samples
are collected.
To avoid possible flakiness due to non-deterministic time required
to start new thread on varios OSs when Sampler and ProfilerEventsProcessor
threads are being started the main thread is blocked until the threads
are running.
Also I removed the heuristic in profile-generator.cc where we try
to figure out if the value on top of the sampled stack is return address
of some frameless stub invocation. The code periodically gives false positive
with the new test ending up in an extra node in the collected cpu profile.
After discussion with jkummerow@ we concluded that the logic is too fragile
and that we can address frameless stub invocations in a more reliable way
later should they have a noticeable effect on cpu profiling.

Fix worst-case behavior of MergeRemovableSimulates().
...
Currently, when a long series of removable simulates are merged, we do
this by merging them one by one as we find them. As we merge the value
value lists of the simulates, those lists snowball so that we get a
quadratic complexity wrt runtime and memory consumption.
Instead, we gather simulates that need to be merged, and merge them
backwards starting from the last simulate.

Refactor parser mode configuration for correctness
...
This patch refactors the parser and preparser interface to be more
readable and type-safe. It has no behavior changes.
Previously, parsers and preparsers were configured via bitfield called
parser_flags in the Parser constructor, and flags in
PreParser::PreParseProgram, ParserApi::Parse, and ParserApi::PreParse.
This was error-prone in practice: six call sites passed incorrectly
typed values to this interface (a boolean FLAG value, a boolean false
and a boolean true value). None of these errors were caught by the
compiler because it's just an "int".
The parser flags interface was also awkward because it encoded a
language mode, but the language mode was only used to turn on harmony
scoping or not -- it wasn't used to actually set the parser's language
mode.
Fundamentally these errors came in because of the desire for a
procedural parser interface, in ParserApi. Because we need to be able
to configure the parser in various ways, the flags argument got added;
but no one understood how to use the flags properly. Also they were
only used by constructors: callers packed bits, and the constructors
unpacked them into booleans on the parser or preparser.
The solution is to allow parser construction, configuration, and
invocation to be separated. This patch does that.
It passes the existing tests.

Codify the assumption that %GetArrayKeys can return only a single interval starting at zero
...
This patch adds comments explaining the interface in runtime.cc and simplifies
all callers given these assumptions (e.g., no need to loop over intervals, or
calculate where the interval starts).
Took care of some unrelated issues in the edited code:
- Fixes one use of [] to InternalArray
- Removed a bunch of comments referring to ES3 which no longer hold in ES5

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".

MIPS: Change LookupForWrite to always do a full lookup and check the result.
...
Port r14061 (df49702a)
Original commit message:
If we find a property in the prototype-chain that we can overwrite, and
we have a transition, keep the holder in the lookup-result as the actual
holder. We will need it for the consistency-check in GenerateStoreField.
By directly checking the entire chain we avoid having to lazily bail out
to a copy of the miss stub while generating the Field Store IC.
Currently this CL disallows a normal non-receiver holder, given that
that would require a positive lookup + details verification to ensure
the property did not become read-only. This fixes the regressions in the
attached tests.

Fix crash involving zombie maps escaping from the JSON parser's underground lab
...
Zapping is required since transition arrays contain weak references to maps: At the end of a GC cycle, ClearNonLiveTransitions removes references to dead maps from transition arrays. If a marked transition array with weak (dead) references is replaced by another transition array before the end of the GC cycle, dead references are not removed from the replaced transition array. If the replaced transition array is kept alive by a handle, marking will crash when trying to mark the first reference to a dead map.

Fix %GetArrayKeys to not skip non-enumerable indices
...
This is one step in the direction of fixing a range of small bugs in the array methods when dealing with non-standard element attributes.
Added tests exercising this behavior for shift and unshift.
For Proxies and Interceptors, the behavior of %GetArrayKeys is now to just return an interval, rather than trying to list all their indexed properties. In the Proxy case, this seems like the only way to avoid an observable difference between smart and non-smart array methods. For Interceptors, the usual case (in WebKit, anyway) is for them to have all indices in [0, length), so enumerating them won't be any better than simply iterating over that range.

Previously we would only mark the slot that was added specifically for
this map, if there was a backpointer and the descriptor array was shared
via the backpointer. However, ConvertTransitionToMapTransition may break
this link after we marked the transitioned map, before we marked the
transitioning map. So the descriptor slots of the parent map won't get
recorded, and we potentially point to an old address of an already
relocated function.

termination exception so that the engine can continue to be used.
* TryCatch::HasTerminated() -- When a TryCatch has caught a termination
exception, HasTerminated() will return true to indicate it is valid to
call V8::ResumeExecution() if desired.
A test case is added to cctest/test-thread-termination.cc.

Turn Flags into a uint32_t typedef.
...
We cannot rely on C++ compilers inferring the int-type from the enum
value range. Whereas Linux/OSX find uint32_t as type for [0,MaxUInt32],
Windows insists it's int.
Update the test to execute its original intent on all platforms: 1 value
larger than max arguments, 1 smaller than max arguments (on all
platforms). This makes the test run a lot faster.

...
Minor cleanups on the way, e.g. making sure that we never use something after an allocation failed. Style question: Should we switch to some kind of MUST_USE_RESULT-style to ensure that we handle failures consistently? Not sure...

MIPS: fix NaN handling of Isolate::StackOverflow()
...
The mjsunit/stack-traces-overflow.js test fails on MIPS target as Error.stackTraceLimit = NaN; should disable stack trace messages and Isolate::StackOverflow() assumes static_cast<int>(double NaN) < 0.
MIPS has a different NaN representation than other architectures so the NaN value casted to int is positive. This patch adds an isnan() check to make the handling of NaN uniform on all architectures.

MIPS: ES6 symbols: Allow symbols as property names
...
Port r13811 (0e64f280)
Original commit message:
Since symbols and strings share a common representation, most of this change is about consistently replacing 'String' with 'Name' in all places where property names are expected. In particular, no new logic at all is necessary for maps, property dictionaries, or transitions. :) The only places where an actual case distinction is needed have to do with generated type checks, and with conversions of names to strings (especially in logger and profiler).
Left in some TODOs wrt to the API: interceptors and native getters don't accept symbols as property names yet, because that would require extending the external v8.h.

MIPS: ES6 symbols: Implement Symbol intrinsic and basic functionality
...
Port r13786 (b5e7a82a)
Original commit message:
- 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).

First of all, it has nothing to do with Isolates, it is related to the assembler
at hand. Furthermore, the saving/restoring is platform-independent. Cleaned up
some platform-specific stuff on the way.
Note that there are some things which still need some cleanup, like e.g. using
EnumSet instead of uint64_t, making Probe() more uniform across platforms etc.,
but the CL is already big enough.

ES6 symbols: Allow symbols as property names
...
Since symbols and strings share a common representation, most of this change is about consistently replacing 'String' with 'Name' in all places where property names are expected. In particular, no new logic at all is necessary for maps, property dictionaries, or transitions. :) The only places where an actual case distinction is needed have to do with generated type checks, and with conversions of names to strings (especially in logger and profiler).
Left in some TODOs wrt to the API: interceptors and native getters don't accept symbols as property names yet, because that would require extending the external v8.h.

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).

ES6 symbols: Introduce Symbol class, along with abstract Name class
...
The new instance type 'Symbol' represents ES6 symbols (a.k.a. private/unique names). Currently, symbols are simple data objects that only carry a hash code, random-generated upon allocation.
The new type 'Name' now serves as the common super class for strings and symbols, and is supposed to represent property names. We will eventually migrate APIs from String to Name for the standard key type.
Strings and symbols share the same hash field representation, via the Name class. This way, we should be able to use the same code paths for symbols and internalized strings in most cases. Also, Symbol's instance type code is allocated adjacent to internalized string codes in the enum, allowing a simple range check for the common case.

This optimization turns out to have a negative effect on i5 processors
throughout the board. This needs further investigation to figure out
the underlying reason but will be rolled out for now.

Currently this mostly just moves code around.
...
- Later the different parts will become individual code objects that tailcall into one another.
- The mapcheck/symbol check still needs to be separated from the overall prototype-chain check so that the ICs can reuse the handlers.

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.

Make __proto__ a foreign callback on Object.prototype.
...
This moves the __proto__ property to Object.prototype and turns it into
a callback property actually present in the descriptor array as opposed
to a hack in the properties lookup. For now it still is a "magic" data
property using foreign callbacks and not an accessor property visible to
JavaScript.
The second effect of this change is that JSON.parse() no longer treats
the __proto__ property specially, it will be defined as any other data
property. Note that object literals still have their special handling.

ARM: Make DoStoreKeyedFixedDoubleArray faster; don't allow conditional Vmov
...
This patch makes us generate faster code for DoStoreKeyedFixedDoubleArray,
by using a branch rather than a conditional Vmov instruction.
Conditional VFP instructions are not a great idea in general, and it was
especially bad in this case because Vmov expands to a bunch of instructions.
For this reason, the patch also removes the 'cond' parameter from Vmov.
Thanks to Rodolph for pointing me to this!

The selection of methods were driven by GCC's -Winline plus some benchmarking.

ARM: Change signature for vmov.32 function in the assembler
...
The assembler has 8 different vmov variants. The one for vmov.32 and for moving
an immediate into a double reg only differs in the type of the second
paremeter: vmov.32 takes an int, the other takes a double.
The situation is dangerous because C++ will happily implicitly convert between
int and double.
This patch changes the signature of the vmov.32 assembler function so that it
cannot be confused with the other vmovs.

This allows Crankshaft to completely inline a f.apply() dispatch if the

deoptimizer doesn't generate the f.apply() frame during deoptimization,
so the materialized frames look like f.apply() did a tailcall.

Simplify secure API functions workaround for MinGW

If MINGW_HAS_SECURE_API is defined, the definitions of localtime_s,
fopen_s, _vsnprintf_s, strncpy_s had to be renamed using #define
so they would not conflict with definitions in the standard headers.
A simpler way to handle this is to undefine MINGW_HAS_SECURE_API before
including the standard headers.

Better fix for MemoryChunk::owner().
...
Pointer arithmetic such as "owner_ - kFailureTag" is undefined behaviour
unless owner_ points to a valid object.
This allowed Clang to assume the subtraction would never be NULL,
causing problems in the caller (see https://codereview.chromium.org/12090072/ ).
To fix this, we should cast owner_ to intptr_t before doing the
arithmetic.

Only mark the descriptor that is valid for the map in question. If this map
...
transitioned from a map with a different descriptor array (or has no back
pointer), mark all valid descriptors from the start.
This fixes the following memory leak: Map A shares a descriptor array
with map B. Map B adds constant function c that in its scope holds on to
an instance of B. If the descriptor array of A would keep all the shared
descriptors alive, including c, this keeps alive both A and c
indefinitely.
This CL also fixes a bug in descriptor array trimming. When trimming
descriptor arrays we need to trim off the slack as well (thus the entire
storage); and since we are trimming a descriptor array, we need to trim
* kDescriptorSize.

Object.observe: don't unnecessarily emit oldValue for reconfigurations of data properties
...
When a data property has its attributes changed but its value remains the same,
don't emit an oldValue. This makes the API more consistent by only emitting
oldValue when the value of a property has actually changed (or been removed,
in the case of a reconfiguration as an accessor property or a deletion).

Also allow the empty object map to keep transitions.
...
With the old implementation, due to the map-check being inadequate, such
transitions were already added for cross-context field stores. It is not
necessary anymore to not store transitions, since we properly clear
non-live transitions. Globally enabling this feature will help find more
bugs.
