6d92511162 Reland "Remove IsInitialized checks from inlined API functions." 
The initialization sequence in Blink has been adapted to use explicit
isolate initialization instead of through calling v8::Null() as the
first API call.

f830fbea3c Simplify stack iterators implementation 
In order to fix https://code.google.com/p/chromium/issues/detail?id=252097 I
need to change SafeStackTraceFrameIterator. Stack iterators hierarchy looks
excessively complicated and I'd like to flatten it a bit by removing some
intermediate classes. In particular there are two hierarchies sharing
JavaScriptFrameIteratorTemp<T> template for no good reason.

This change extracts some of JavaScriptFrameIteratorTemp functionality directly
into SafeStackTraceFrameIterator. This made it obvious that a few checks were
performed twice.

The rest of JavaScriptFrameIteratorTemp<T> is merged with
JavaScriptFrameIterator. Now that the class is not a template some of its
implementation is moved from frames-inl.h into frames.cc

So in this change I removed JavaScriptFrameIterator and
SafeJavaScriptFrameIterator. As the next step I'm going to merge
SafeStackFrameIterator into SafeStackTraceFrameIterator.

54483c4880 MIPS: Generators: Avoid calling into runtime if operand stack is empty 
Port r15240 (909f716e)

Original commit message:
This patch makes yield sites save the resume continuation and context
inline.  If the operand stack is empty, we can avoid a call into the
runtime.  This also makes the SuspendJSGeneratorObject runtime function
less magical: it just has to save the operand stack and stack handlers.

This speeds up the following case by a factor of 3 or so:

  function* until(n) {
    for (var i = 0; i < n; i++)
      yield i;
  }

  function sum(iter) {
    var sum = 0;
    for (var x of iter) sum += x;
    return sum;
  }

  for (var i = 0; i < 10000; i++) sum(until(1000))

Also, there is no more sentinel value as the generators will resume in
the right place already, allowing me to remove the hack added to the
--debug-code check in r14437.

6a91645a84 MIPS: Fix stack frame reconstruction for generators with formal arguments. 
Port r15230 (e2bbe01)

Original commit message:
The formal parameter count was always being treated as an untagged
integer, but it is actually a Smi on ia32 and arm.

c7b3ef0e05 Make sure ExternalCallbackScope is always created when VM state changes to EXTERNAL 
ExternalCallbackScope is used to let CPU profiler know which API callback is being executed. Whenever such callback is called we should create VMState<ETERNAL> and ExternalCallbackScope. This patch fixes several places where VMState<ETERNAL> went without ExternalCallbackScope.

646a34e1e0 Generators: Avoid calling into runtime if operand stack is empty 
This patch makes yield sites save the resume continuation and context
inline.  If the operand stack is empty, we can avoid a call into the
runtime.  This also makes the SuspendJSGeneratorObject runtime function
less magical: it just has to save the operand stack and stack handlers.

This speeds up the following case by a factor of 3 or so:

  function* until(n) {
    for (var i = 0; i < n; i++)
      yield i;
  }

  function sum(iter) {
    var sum = 0;
    for (var x of iter) sum += x;
    return sum;
  }

  for (var i = 0; i < 10000; i++) sum(until(1000))

Also, there is no more sentinel value as the generators will resume in
the right place already, allowing me to remove the hack added to the
--debug-code check in r14437.

f8fc5c443e Allow running mjsunit/manual-parallel-recompile on single-core systems. 
- Add an %IsParallelSupported() builtin function to  make possible to check support of parallel processing from JavaScripts.
- Change the test script that if parallel recompilation is forced on a single core CPU, expect that it won't be recompiled in parallel.
- Change the  JSFunction::MarkForParallelRecompilation() to fall back gracefully if parallel recompilation is not supported.

bcf5912b3f Reduce the amount of full code generated to fill out array literals. 
This is achieved by tuning the calling convention of StoreArrayLiteralStub:

 * The map of the array literal can be loaded in the stub from the
   array literal itself, there is no need to pass it at all.

 * The array literal is already on the stack, so there is no need to
   pass it again via a register.

 * The literal index is unchanged while filling the literal, so we can
   push it on the stack once and avoid passing it every time. Note that
   we need to mirror this change in the stack layout in crankshaft, too.

c4224f09a2 Notify CPU profiler when calling native getters 
This change modifies code produced by BaseLoadStubCompiler::GenerateLoadCallback so that instead of calling AccessorGetter direcly it calls InvokeAccessorGetter which changes VM state and calls the actual callback. This way CPU profiler knows which external callback is being executed in this case. Indirect call happens only if CpuProfiler::is_profiling() is true.

This is exactly same change as r15116 with a build fix for test-api.cc

1a3c3cee9d Notify CPU profiler when calling native getters 
This change modifies code produced by BaseLoadStubCompiler::GenerateLoadCallback so that instead of calling AccessorGetter direcly it calls InvokeAccessorGetter which changes VM state and calls the actual callback. This way CPU profiler knows which external callback is being executed in this case.

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.

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.

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).

70ce03c19d MIPS: Turn off allocation site info for crankshafted array constructor calls. 
Port r14934 (dbddd7e)

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.

74a06647cc MIPS: Deprecate FACTORY helper macro. 
Port r14931 (a914442)

Original commit message:
This removes the FACTORY helper macro to avoid accidental TLS access
when using the factory. Most internal code has access to the Isolate by
now whereas tests which are not performance critical still heavily use
TLS access through explicit Isolate::Current() calls.

This makes sure processing of Harmony weak maps is only triggerd twice
during a mark-compact collection. Note that the processing itself still
is a fix-point iteration with quadratic worst-case time.

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.

09c489ea93 Re-land: Implement ObservedArrayPop, ObservedArrayShift, ObservedArrayUnshift & ObservedArraySplice 
Original issue: https://codereview.chromium.org/15331002/

Broke mozilla/js1_5/Array/regress-451483.js, which ends up attempting to call %IsObserved() on a non-object.

IsObserved now checks for JSReceiver and returns false rather than crashing.

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.

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.

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)

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).

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.

Encapsulate type information in a convenient wrapper instead of storing it in a naked bitfield. This especially facilitates transitioning to a new state and converting from/to the extraICState representation. Additionally cleaning up ToBooleanICStub::Types for consistency.

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.

c1bc396c2d Consistently assume that arithmetic operations can overflow unless one can prove the opposite. 
Previously, HDiv never had its CanOverflow flag cleared and HMod had
inverted logic (compared to HAdd, HSub and HMul). Minor cleanups on the way.

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.

Two tiny changes:

  * Some phases were missing an HPhase, which was added, so we can now see all
    phases in the visualizer output.

  * Consistently test commandline flags directly in the pipeline, making it
    clearer which parts are optional and which are not.

75d939aceb Generators save and restore stack handlers 
This CL adds machinery to unwind stack handlers from the stack and store
them into a generator's operand array.  It also includes routines to
reinstate them.  Together this allows generators to yield within
try/catch and try/finally blocks.

e5a29e8ff9 Do not change environment between simulate and scope with no observable side-effects in HandlePropertyAssignment. 
LChunkBuilder reconstructs the environment by applying simulates. A scope with no observable side-effects has no simulates. If the scope deoptimizes, then LChunkBuilder would miss the changes to the environment between the last simulate and the scope.
