837276829e Fix HasResult method of LTemplateInstruction to properly handle LCheckSmi 
LCheckSmi sometimes has a result register and sometimes not, even though its
LTemplateInstruction alwasys has room for one. Debug output use HasResult to
determine whether it was ok to de-ref result(), but HasResult doesn't check for
the case where LTemplateInstruction has a result but it's NULL.

e9cc78af7e Fix for V8 issue 2795: Check fails with deopt for mjsunit/array-store-and-grow 
(https://code.google.com/p/v8/issues/detail?id=2795)

The reason is when allocating and building arrays in hydrogen we need to ensure
we do any int32-to-smi conversions BEFORE the allocation. These conversions can
at least theoretically deoptimize. If this happens before all the fields of the
newly allocated object are filled in, we will have a corrupted heap.

141ada02f2 Logger: introduce abstract interface for CodeEvent listeners. 
New abstract class CodeEventListener was created.

CodeEventLogger which is the base class for Jit, LowLevel
and CodeAddressMap loggers was inherited from CodeEventListener.

CodeAddressMap class was moved to serializer.cc because serializer is the only user for it. Actually it collects code names and pushes them to the standard log as SnapshotCodeNameEvent. So I extracted this code into separate function CodeNameEvent. It happens that this method works only when Serializer serializes an object. So I added direct log call there.

CodeEventLogger class declaration was moved to the header
because CodeAddressMap needs it.
The code for the nested class CodeEventLogger::NameBuffer was left in the cc file.

CpuProfiler now is inherit CodeEventListener but not used
the loggers infrastructure yet due to the complex initialization schema. I'd like to fix that in a separate cl.

372763897d Lazy call to custom stack trace formatting using Error.prepareStackTrace. 
This enables custom stack trace formatting for stack overflow.
A consequence is that stack trace formatting is now easily observable,
but we already established that the default stack trace formatting can
be observed anyways. It is only triggered by the .stack getter, and
it has to be explicitly called, (e.g. not implicitly after GC).

f5e6fbef6e move 32 bit heap hint on sunos 
Setting the V8 heap at or near 0x20000000 on 32bit sunos only allows
512 MB of heap space, instead on sunos move this to 0x80000000.

To quote the comment

For our Solaris/illumos mmap hint, we pick a random address in the bottom
half of the top half of the address space (that is, the third quarter).
Because we do not MAP_FIXED, this will be treated only as a hint -- the
system will not fail to mmap() because something else happens to already
be mapped at our random address. We deliberately set the hint high enough
to get well above the system's break (that is, the heap); Solaris and
illumos will try the hint and if that fails allocate as if there were
no hint at all. The high hint prevents the break from getting hemmed in
at low values, ceding half of the address space to the system heap.

This adds an early check to the graph builder which prevents adding an
HWrapReceiver instruction if the receiver type is already known at graph
building time. Also HAllocate no longer unnecessarily postpones setting
it's type until type inference but sets it right away. These changes are
in preparation for escape analysis.

97f8f91bb5 Fix call stack sampling for the case when native callback invokes JS function 
The SafeStackFrameIterator used by CPU profiler checked if Isolate::c_entry_fp is null and if it is not it would think that the control flow currently is in some native code. This assumption is wrong because the native code could have called a JS function but JSEntryStub would not reset c_entry_fp to NULL in that case. This CL adds a check in SafeStackFrameIterator::IsValidTop for the case when there is a JAVA_SCRIPT frame on top of EXIT frame.

Also this CL changes ExternalCallbackScope behavior to provide access to the whole stack of the scope objects instead of only top one. This allowed to provide exact callback names for those EXIT frames where external callbacks are called. Without this change it was possible only for the top most native call.

19fdbc2653 Logger: extract CodeEventLogger classes. 
The idea is to extract all the CodeEvent loggers into separate classes
make an interface for code events and put them into a listeners array.

I extracted code that works with name_buffer into a separate base class CodeEventLogger.
And made JitLogger, LowLevelLogger and new CodeMap its descendants.

As a side effect I converted NameBuffer into nested class of CodeEventLogger
and converted NameMap into nested class of CodeMap.

Port r15773 (60aa9f0)

Original commit message:
With >= 64 non-string instance types, I removed an optimization that allowed us to detect internalized strings with a single bit test. (https://code.google.com/p/v8/source/detail?r=15358) But that change caused a regression, so here is an improvement:

Put the internalized string types in the lower 64 entries of
INSTANCE_TYPE, and non-internalized string types in the next 64 entries.
This way we can restore the single bit check.

4c3269a43d Fix unaligned accesses in back_edge tables. 
This patch fixes the step size of masm->pc_ in back_edge tables to words (4 bytes) to ensure 4 bytes alignment for read/write operations. Read and write of words (4 bytes) data from aligned space (address % 4 == 0) is more efficient on all platforms and especially on MIPS where without this alignment fix a kernel exception handler is used for every unaligned access.

This patch increases the size of back_edge tables by 3 bytes in every row. By the test it seem the back_edge table quite small in every/most cases (maximal length is 18 so in that case there are only 54 additional bytes with this patch).

02649f08bc Implement simple effect typing for variables 
For that, we maintain an abstract store typing of all variables with LOCAL location (i.e., those that do not escape the function's own scope). We treat assignments as sequential effects that modify this store.

When control flow branches, we have to compute the disjunction of possible effects. To that end, we represent the store as a stack of effect sets, such that we can cheaply push and pop "local" effects when control flow has to branch.

In cases of non-local control transfer from an unknown source, we currently erase all knowledge about the store.

The 'switch' statement is still to come.

For a formulation of the typing rules, see:

https://docs.google.com/a/google.com/file/d/0B3wuXSv9YKuKeUNkVXZDemZ0Z1E

97681be4e5 Fix data race in SamplingCircularQueue 
This change fixes data race described in the bug by adding Acquire_Load to SamplingCircularQueue::StartDequeue and Acquire_Store to SamplingCircularQueue::Enqueue.

Also the queue implementation imposed a constraint on the records it stored: the first AtomicWord in each record was a marker. For that purpose TickSampleEventRecord had filter field of type int. This approach is error prone, e.g. on x64 sizeof(AtomicWord) is 8 while sizeof(int) is 4. Moreover the queue needs such marker only at the beginning of chunk. I changed the queue so that it stores the marker explicitly as the first Cell in chunk and removed the filter field.

462f6be930 MIPS: The gc should be able to traverse all AllocationSites for decision making. 
Port r15715 (2e830d4)

Original commit message:
The gc should be able to traverse all AllocationSites for decision making. The sites are threaded into a weak list. Special problems include:

* Allocations of AllocationSites occur in generated code, so generated code needs to be able to add to the list. For now I have a special hydrogen instruction, though it would be nice to use general purpose instructions.
* The snapshot contains AllocationSites, and these need to be re-threaded into the list on deserialization.

Something nice is that the AllocationSites are only created in old space, so a special new space visitor isn't required.

a72b5d6c4d Fix invalid array length check in TransitionElementsKindStub. 
The stub used to check the length of the JS array to see if
there's a need to duplicate the elements backing store. This
way it will not duplicate the elements array when going from
double to object even if the elements array is not the empty
fixed array. Later on it will then store pointers into a
FixedDoubleArray.

The native code stub used to check whether elements points to
the empty_fixed_array singleton instead of testing the length.
The Hydrogen stub does that as well now.

Further refinement to semantics that I have missed in previous change.
Both Blink and Firefox are permissive with arguments to .set method.
However, when first argument to "set" is a number, all implementations
throw, so that users know that
   a.set(0,27)
does not assign 27 to 0th element of a, not 0 to 27th element of a.

fab9f4e126 [Object.observe] Lazily allocate callbackInfo structure 
This patch allows callbacks to lazily allocate the InternalArray which is used to store pendingChangeRecords. This moves some of the expense of observation to the case where changes actually occurred.

When there are no pendingChangeRecords, the callbackInfo structure is a number which is the callbacks priority. Whenever a changeRecord is enqueued to the callback, it "normalizes" to be an InternalArray with a priority property. Immediately before its changeRecords are delivered, it returns to its optimized state.

---
Note: Naming confusion resolved:

This patch corrects some naming confusion in object-observe.js. Previously, we used the terms "callback" and "observer" to mean roughly the same thing, and overloaded the term "observer" to be both the callback itself and the *registration* on a object to observe (which now includes an accept map).

This patch resolves this confusion:

"object" (objectInfo, objectInfoMap): This refers to the observed object and its structures

"callback" (callbackInfo, callbackInfoMap): This refers to the callback to whom change records may be delivered

"observer" (objectInfo.changeObservers): This refers to a registration to observe a given object by a given callback with the specified accept list.

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.

c65f4f7f7b Don't use StoreIC_ArrayLength on frozen arrays 
The code previously assumed that an array with fast properties must have
a writable length property. But Object.freeze() now exposes a way to make
length read-only without moving the object into slow mode. This patch
simply adds a !is_frozen check to the IC code. Any future optimizations
to attribute-setting on JSArrays will need to make similar accomodations.

b7a2c88f0f MIPS: Do not omit the write-barrier if the input value is a smi. 
Port r15573 (3954d53)

Original commit message:
ARM: Do not omit the write-barrier if the input value is a smi.
The input value isn't what is written into the field if the representation is double. A heap-number is written to the field instead; which requires a write-barrier.

the FP-saved version of StoreBufferOverflowStub available
at snapshot time. This stub was added to ARM by commit r14359.

82d8580215 MIPS: Bugfix: The general array constructor stub did not handle the case properly when it is called with a function pointer in the type cell, instead assuming that an AllocationSite object should be present. 
Port r15555 (262c081)

Original commit message:
The case where this can happen is if the cell is uninitialized, then the
first constructor call made is to the Array function of a different
context. In that case, we'll store the function pointer in the cell,
and then go ahead and call the array constructor stub too. The bug is
fixed by checking for the AllocationSite object map. If not found, the
constructor stub goes forward with a default ElementsKind, just as in
several other cases.

A test in allocation-site-info.js was beefed up to make sure the state
chain described above is traversed.

Now that console.profiles is removed and corresponding V8 API methods have been deprecated in 3.19 branch(https://code.google.com/p/v8/source/browse/branches/3.19/include/v8-profiler.h) it is safe to remove all that code.

79ce581420 MIPS: Generate StoreGlobal stubs with Hydrogen. 
Port r15512 (bdf9918)

Original commit message:
- Constants globals are inlined into Hydrogen code using code dependencies that invalidate the Crankshafted code when global PropertyCells or the global object change.
- The more general case generates code that is just as good as the hand-written assembly stubs on all platforms.

7e0ee5301e Add internal fields to JSArrayBufferViews (JSTypedArray and JSDataView) 
In Blink, JSTypedArray and JSDataView objects act as "wrappers" for C++
objects. Wrapping protocol in Blink requires all wrapper JavaScript objects
to have a certain amount of internal fields that Blink uses for
book-keeping (essentially a pointer to C++ object and some type
information). This change adds those internal fields to JSTypedArray and
JSDataView, in a similiar way to how it is done for JSArrayBuffer.

Some common pieces were moved from platform-dependent code into Sampler::SampleStack and TickSample::Init.

When pc is inside FunctionApply builtin function the top frame may be either
2) Internal stack frame created by FunctionApply itself.
In this case we know its caller's pc and can correctly resolve calling function.
1) Frame of the calling JavaScript function that invoked .apply(). In this case we have no practical reliable way to find out the caller's pc so we mark the caller's frame as 'unresolved'.

All this logic is implemented in ProfileGenerator. SafeStackFrameIterator is extended to provide type of the current top stack frame (iteration actually starts from the caller's frame as we know top function from pc).

4c5508b42f Correctly report callstack when current function is FunctionCall builtin 
When current function is FunctionCall builtin we have no reliable way to determine its caller function (in many cases the top of the sampled stack contains address of the caller but sometimes it does not). Instead of dropping the sample or its two top frames we simply mark the caller frame as '(unresolved function)'. It seems like a better approach that dropping whole sample as knowing the top function and the rest of the stack the user should be able to figure out what the caller was.

This change adds builtin id to CodeEntry objects. It will be used later to add similar top frame analysis for FunctionApply and probably other builtins.

0ac0edb707 Test that profiler is stopped when isolate is being disposed 
The only way to get v8::CpuProfiler instance in the V8 public API is to call v8::Iolate::GetCpuProfiler(). The method will return NULL if the isolate has not been initialized yet or has been torn down already. It is the client's reponsibility to make sure that CPU profiling has been stopped before disposing of the isolate.

This CL adds a test for this and several ASSRTS enforcing that assumptions. This allowed to be sure that heap is always setup when CPU profiling is being started. Based on that the number of places where already compiled functions are reported to the profiler event processor boils down to the single place (CpuProfiler::StartProcessorIfNotStarted). I'm going to rely on this assumption in further changes.

ca90f4b058 CpuProfiler: eliminate 2 layers of 4 for CodeCreateEvent calls. 
The bodies of methods in ProfilerEventProcessor were moved into CpuProfiler.
Multiple NewCodeEntry methods in CpuProfilesCollection were replaced with one which
simply passes arguments to the CodeEntry constructor.
And CpuProfiler just calls this method when it needs a CodeEntry object.

This NewCodeEntry method is required because CpuProfilesCollection keeps ownership of CodeEntry objects.

daf4101aa4 Fix infinite loop in regress-opt-after-deopt. 
%CompleteOptimization attempts to install optimized functions
that the parallel thread has put on the output queue, as long as
the function is marked with a builtin.  However, activating the
debugger will set all functions to the lazy recompile builtin,
without the function being on the parallel recompilation pipeline.
So we wait for the function to finish parallel recompilation
while it's marked by a builtin that's unrelated to parallel
recompilation.

081a9d1791 MIPS: Hydrogen array constructor cleanup and improvements. 
Port r15383 (3e90aaf)

Original commit message:
* Cleanup of LCallNewArray::PrintDataTo() method
* Created HCallNewArray::PrintDataTo()
* Created many more tests in array-constructor-feedback.js
* Removed redundant instructions in
GenerateRecordCallTarget
* Bugfix in CreateArrayDispatchOneArgument: on a call to
new Array(0), we'd like to set the type feedback cell to
a packed elements kind, but we shouldn't do it if the
cell contains the megamorphic sentinel.
* When used from crankshaft, ArrayConstructorStubs can
avoid verifying that the function being called is the
array function from the current native context, relying
instead on the fact that crankshaft issues an
HCheckFunction to protect the constructor call. (this
new minor key is used in LCodeGen::DoCallNewArray(), and
influences code generation in
CodeStubGraphBuilderBase::BuildArrayConstructor()).
* Optimization: the array constructor specialized for
FAST_SMI_ELEMENTS can save some instructions by looking
up the correct map on the passed in constructor, rather
than indexing into the array of cached maps per element
kind.

98786ae073 Refactor Hydrogen GVN into an HPhase and use the phase zone. 
The HGlobalValueNumberer class is renamed to HGlobalValueNumberingPhase,
following the naming scheme suggested by danno@chromium.org in
https://codereview.chromium.org/17458002

The GVN phase now uses the phase zone for all its allocations.

52d848bce7 Extract StackFrameIteratorBase 
This change introduces StackFrameIteratorBase which owns singleton frame instances and encapsulates some basic iterator functionality. It has two actual implementations: StackFrameIterator and SafeStackFrameIterator.

All logic specific to frame iteration at a random point (basically checks that fp and sp extracted from stack frames are within current stack boundaries) used only by CPU profiler is now concentrated in SafeStackFrameIterator.

Generic stack iteration used in all other places is put into StackFrameIterator. Also this iterator unlike SafeStackFrameIterator iterates through stack handlers.

StackAddressValidator and ExitFrameValidator classes were removed in favor of inline checks and simple methods.

4aeccdb23e Do not iterate stack handlers in SafeStackFrameIterator 
CPU profiler doesn't use stack handlers so there is no need to iterate through them while traversing stack. This change SafeStackFrameIterator always iterate only frames and removes checks corresponding to the handlers iteration.

The problem described in the bug occurred because of a false assumption in SafeStackFrameIterator that if Isolate::c_entry_fp is not NULL then the top frame on the stack is always a C++ frame. It is false because we may have entered JS code again, in which case JS_ENTRY code stub generated by JSEntryStub::GenerateBody() will save current c_entry_fp value but not reset it to NULL and after that it will create ENTRY stack frame and JS_ENTRY handler on the stack and put the latter into Isolate::handler(top). This means that if we start iterating from c_entry_fp frame and try to compare the frame's sp with Isolate::handler()->address() it will turn out that frame->sp() > handler->address() and the condition in SafeStackFrameIterator::CanIterateHandles is not held.

The counter is used by stack frames implementations to avoid accessing pointers to heap objects when traversing stack for CPU profiler (so called "safe" mode). Each StackFrame instance is owned by single iterator and has a pointer to it so we can simply mark the iterator as "safe" or not and read the field in the stack frames instead of going into the isolate.

a0f41ad31a In revision 15142, the V8_USE_UNSAFE_HANDLES define is removed. 
So in the vtune support code ( in vtune-jit.cc file)v8::Handle<T* value> consturctor cannot be invoked directly.
We use "->ToString()" to create the Handle<String> object  to fix the compilation error.

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.

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.

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.

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.

1d4c64591b MIPS: Fix abs_d instruction in the simulator. 
The abs_d instruction was implemented wrongly in the simulator,
it doesn't reverse the sign of the -0 number.

This commit fixes the abs_d instruction implementation.

Port r15027 (3ffb343)

Original commit message:
The comments in ic-arm.cc::LoadIC indicated that the receiver should be
both in a register and on the stack. This isn't true in fact: the code
is careful to spill the receiver if needed.

This CL also fixes up a mistaken use of this convention in VisitYield.

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)

cb0d146862 Add initial parser support for harmony iteration 
This commit adds initial parser support for harmony iteration.
Specifically, it will parse:

  for (x of y) {}
  for (let x of y) {}
  for (var x of y) {}

The semantics are still unimplemented.

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).
