6124e8f141 MIPS: Allow the deoptimizer translation to track de-materialized objects. 
Port r15087 (63e1626)

Original commit message:
This allows the deoptimizer to materialize objects (e.g. the arguments
object) while deopting without having a consective stack area holding
the object values. The LEnvironment explicitly tracks locations for
these values and preserves them in the translation.

2a56e33da7 MIPS: Allocate generator result objects before unwinding try handlers 
Port r15079 (1ebdfdc6)

Original commit message:
When a generator suspends, it saves its state out to the heap and
unwinds try handlers but doesn't pop anything off the stack.  Instead it
relies on no GC happening between the suspend and the return from the
generator.  However this was not the case: boxing the result object
could cause GC, which would try to traverse the stack but would
misinterpret words from unwound try handlers as heap objects.

This CL changes to allocate the result objects before the suspend.  It
also removes the generators-iteration skip introduced in r15065.

cc27c4c41b GeneratorFunction() makes generator instances 
The current specification has GeneratorFunction() be like Function(),
except that it makes generator instances.  This commit implements that
behavior.  It also fills in a piece of the implementation where
otherwise calling GeneratorFunction or GeneratorFunctionPrototype would
cause an abort because they have no code.

66bb4c5b8d Improve code for integral modulus calculation. 
Depending on what we know about the right operand, we basically do 3
different things (and the code is actually structured this way):

* If we statically know that the right operand is a power of 2, we do
  some bit fiddling instead of doing a "real" modulus calculation.
  This should actually be done on the Hydrogen level, not on the
  Lithium level, but this will be a separate CL.

* If type feedback tells us that the right operand is a power of 2, we
  do the same as above, but guarded by conditional deoptimization to
  make sure that the assumption is still valid. In the long run, we
  should make this guard visible on the Hydrogen level to make it
  visible for GVN and other optimizations.

* In the general case we only do the minimum steps necessary and don't
  try to be too clever, because cleverness actually slows us down on
  real-world code.

If we look at the code gerators for LModI, we actually see that we
basically have 3 (4 on ARM) fundamentally different translations. I
don't really like lumping them together, they should probably be
different Lithium instructions. For the time being, I restructured the
generators to make this crystal-clear, at the cost of some duplication
regarding the power-of-2 cases. This will go away when we do the
strength reduction on the Hydrogen level, so I'd like to keep it as it
is for now.

Note that the MIPS part was only slightly restructured, there is still
some work to do there.

Current approach is to find breakpoint by the statement position that was used when setting breakpoint. This doesn't work when setting breakpoint by anything else but statement position.

(Question: could PC of existing breakpoint change, for example because of recompilation, or this approach is safe)

a9a80fb422 Allocation type info advice consumed in bailout path leads to assert failure. 
If the runtime is taken for a constructor like "new Array(100000)", where
allocation site info already led to an elements kind of DOUBLE, then the runtime
would fail to transition the array to dictionary mode. Better to recognize this
case and avoid wasting time by following the advice. Furthermore, it offers a
way to recognize that the array should be in dictionary mode (though a future
checkin will capitalize on that).

Original commit message:
Once we crankshaft a method, we should turn off allocation site info for
constructed arrays. Additionally, the semantics for doing this were
awkward because the constructed array code stubs get an
AllocationSiteMode as a minor key, but it's used as a permission to
determine the final mode locally based on ElementsKind. I refactored
this to a simpler boolean for override or local control.

106a477443 CPU profiler should support names of accessors set via v8::Object::SetAccessor 
This change fixes the case when the accessors are invoked from JSObject::{Get,Set}PropertyWithCallback.

It already works for inlined calls generated by StoreStubCompiler::CompileStoreCallback. The same still needs to be fixed for getter invocations generated by  BaseLoadStubCompiler::CompileLoadCallback, corresponding case is commented out in the new test.

This is a slightly modified version of r14915 which was rolled back due to test timeout on Windows. Compared to r14915 the new tests use OS::TimeCurrentMillis instead of OS::Ticks as OS::Ticks has ms precision on Windows and trying to wait 10 ticks (us) will result in at least 1 ms pause.

710c245a41 CPU profiler should support names of accessors set via v8::Object::SetAccessor 
This change fixes the case when the accessors are invoked from JSObject::{Get,Set}PropertyWithCallback.

It already works for inlined calls generated by StoreStubCompiler::CompileStoreCallback. The same still needs to be fixed for getter invocations generated by  BaseLoadStubCompiler::CompileLoadCallback, corresponding case is commented out in the new test.

https://src.chromium.org/viewvc/blink?revision=151136&view=revision
https://src.chromium.org/viewvc/blink?revision=151196&view=revision
this method can be deprecated and all the code that supports filtering
CPU profiles based on security origins can be later removed.

Drive-by fix: in line with CpuProfiler changes deprecated HeapProfiler::FindHeapSnapshot to reduce v8 API surface. FindHeapSnapshot may well be implemented based on existing GetSnapshotCount/GetSnapshot and it is only used in the tests.

6fda4e4c28 Collect type feedback in separate pass and store it in AST 
Notes:

- For now, just adds the missing type info fields to the AST nodes directly.
  I'd like to factor that out more nicely in a follow-up CL.

- All type feedback now is uniformly collected through AST nodes'
  RecordTypeFeedback functions. At some point, this logic should be moved
  out of ast.cc.

- The typing pass currently simulates the exact same conditions under
  which feedback was collected in Hydrogen before. That also should be
  made more generic in the future.

- Type information itself is unchanged. Making it more regular is
  yet more future work.

Some additional cleanups:

- Lifted out nested class ObjectLiteral::Property, to enable forward declaration.
- Moved around some auxiliary enums.

9d3e7e5b81 Fix Object.freeze for objects with mixed accessors and data properties 
The bug in the existing code was that it modified the |attributes|
local variable on its way through the loop in CopyUpToAddAttributes.
But that affected any properties updated after an accessor property.
The code now sets up a mask each time and applies that instead of
mutating |attributes|.

3e41834721 Regexp parser: reset flag after scanning ahead for capture groups. 
When the regexp pattern parser encounters an unbound reference to a
capturing group, it needs to scan ahead to decide whether it really
is a reference.  The scan advances to the end of the pattern string
and sets has_more_ to false, but fails to reset it to true so that
later on, parsing a character class wrongly fails.

7aa74c3dc5 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)

7c2a1346d6 Fix edge case in stack trace formatting. 
Bug description: in strict mode, null as receiver is not implicitly converted
to the global object, so that when formatting the stack trace, the receiver of
the stack frame is null. The IS_OBJECT check returns true for null, but
%GetDataProperty expected a JSObject, which results in a failed RUNTIME_ASSERT.

94b4240f5c Introduce ObjectAccess, which is used by LoadNamedField and StoreNamedField to denote what parts of an object are referred to by a given load or store. Refactor HGraphBuilder to use ObjectAccess, which removes the need to manually set GVN flags and simplifies the code as well.

36e91242fd 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).

45ec481659 ARM: Smi refactoring and improvements. 
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.

22fe386d6f 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.

69c2f54d32 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.

8f602260d3 Implement yield* (delegating yield) 
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.

3f09e0a3d8 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.

885fd2f4b2 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.

7b2abd7c1e MIPS: Capture receiver in generator object 
Port r14434 (04f254d1)

Original commit message:
Previously there has been no reason to context-allocate the receiver, so
access to the receiver always goes through the stack.  This was failing
with generators, which assumed that forcing context allocation would
relieve the need of storing anything but the context and the function on
the stack.

This CL adds a slot in generator objects to capture the receiver, and
restores it when resuming a generator.

7ed7af2f9f Tell the GC prologues to construct RetainedObjectInfos only when needed. 
The GC prologue is called by the GC, but also by the heap snapshotter. The
RetainedObjectInfos are only needed by the heap snapshotter, so it's wasteful to
construct them always. (And it will be even more wasteful when Blink migrates to
the new GC APIs, since after that point it no longer knows about object groups.)

71dc9e165f Capture receiver in generator object 
Previously there has been no reason to context-allocate the receiver, so
access to the receiver always goes through the stack.  This was failing
with generators, which assumed that forcing context allocation would
relieve the need of storing anything but the context and the function on
the stack.

This CL adds a slot in generator objects to capture the receiver, and
restores it when resuming a generator.

8ddaa0c1a5 MIPS: Generators can resume 
Port r14415 (d358defa) and r14424 (7b549ce7)

Original commit message:
The generator object methods "next", "send", and "throw" now
include some inline assembly to set up a resumed stack frame.  In some
common cases, we can just jump back into the frame to resume it.
Otherwise the resume code calls out to a runtime to fill in the operand
stack, rewind the handlers, and possibly to throw an exception.

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.

07a2a9cd19 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.

f51b76425a MIPS: Generator objects can suspend 
Port r14353 (f4bb81d1)

Original commit message:
* src/ast.h:
* src/parser.cc: Differentiate between the different kinds of yields, in
  anticipation of boxing return values.  Parse `return' into `yield' in
  a generator.

* src/runtime.h:
* src/runtime.cc (Runtime_SuspendJSGeneratorObject): New horrible
  runtime function: saves continuation, context, and operands into the
  generator object.

* src/arm/full-codegen-arm.cc (VisitYield):
* src/ia32/full-codegen-ia32.cc (VisitYield):
* src/x64/full-codegen-x64.cc (VisitYield): Arrange to call
  SuspendJSGeneratorObject.  If the call returns the hole, we suspend.
  Otherwise we resume.

BUG=v8:2355
TEST=These codepaths are tested when the generator is first invoked, and so
are covered by mjsunit/harmony/generators-objects.js.

8bbf942d75 Remove heap snapshot size limit. 
As long as frontend now stores snapshots in external arrays
it doesn't make sense to check the collected snapshot size on the
backend side. In other words if backend has managed to fit the
collected snapshot into its memory, it should also fit into the
frontend's memory.

caa37597ad 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.

102c5170c2 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.

1596afa7f9 Move *BSD and Solaris Sampler implementation into sampler.cc 
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.*

f5b660ac97 Intel VTune integration for V8/d8 
In this patch, we added the JIT code event handler for Vtune. Most of the code is in the
folder src/third_party/vtune. Two APIs are added in include/v8.h to get the requirement info
from V8.

We add the v8_enable_vtunejit parameter for GYP to enable these Vtune code compilation.
vTune::InitilizeVtuneForV8() is invoked in the embedder of V8 to make sure it's invokded if
vtune support is enabled.

Corresponding logic was removed from profile-generator.cc in r14205 (see https://code.google.com/p/v8/source/diff?spec=svn14205&r=14205&format=side&path=/branches/bleeding_edge/src/profile-generator.cc) and now it is time to remove it from the tick processor.

Since the tos is not used anymore by profiler it is also removed from TickSample.

75c388e691 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.

dcd3f06b27 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.

dc72037e10 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.

c7ce87f865 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.

9559181b0e 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.

b67e017b4a Remove unnecessary explicity prototype check. 
The prototype is implicitly checked through a map check of the holder.
This is either checked in CheckPrototypes, or as part of the IC.

d71678676f 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.

2816f19680 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".
