* 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
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.

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".

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.

addresses that without regressing other platforms.
Instead of looking at the exponent of double_input and trying to figure
out if the conversion will overflow, eagerly do the VCVT and return
early unless it saturated.

Fix huge heap snapshot when a heavily shared context has many variables

Prevously v8 put a link to each context variable into a function where
the variable is visible.
Because of that if there are N functions sharing a context having M variables
then N*M links were created for the snapshot.
The fix makes v8 to put the links into the context object.

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).

fix x32 handling of Atomic64
...
The x32 logic for the size of Atomic64 handles NaCL, but misses
the Linux case. Check the standard __ILP32__ to handle that too.
This has been fixed in the Chromium base tree already:

Cleaned up CpuFeature scope handling.
...
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.

Add workaround for redefinition of __proto__ property.
...
This is a temporary workaround when the __proto__ property is being
redefined (e.g. by Object.freeze()) to not loose the foreign callback.
Once the __proto__ property is a real JavaScript accessor this hack is
no longer necessary. This change also makes __proto__ configurable.

Make sure builtin functions don't rely on __proto__.
...
This makes sure that none of the builtin functions rely on the __proto__
accessor which can now be monkey-patched by applications. Instead use a
separate %SetPrototype() intrinsic or object literals to do the job.
