a797a35975 Refactor and cleanup VirtualMemory. 
Remove a lot of platform duplication, and simplify the virtual
memory implementation. Also improve readability by avoiding bool
parameters for executability (use a dedicated Executability type
instead).

Get rid of the Isolate::UncheckedCurrent() call in the platform
code, as part of the Isolate TLS cleanup.

Use a dedicated random number generator for the address
randomization, instead of messing with the per-isolate random
number generators.

f6b7ec4da0 HeapProfiler: very slow ~4min "take snapshot time" for 80MB gmail heap. 
The reason of that is a number of cons strings in the app.
The app constructs a json string and as a result v8 heap has
a very long chain of cons strings.

Profiler counts all these strings as plain String objects and
assign the content of the strings as node names.

It required O(n^2) time and O(n^2) memory.

Solution: I introduced two new types, kConsString and kSliced string.
They do not use the content of the string for names. So the problem disappeared.

The heap profiler usability problem will be solved on Blink side.

4ef84b9240 Add a ResourceConstraint for the embedder to specify that V8 is running on a memory constrained device. 
This enables us to specialize certain operations such that we limit memory
usage on low-memory devices, without reducing performance on devices which
are not memory constrained.

bbd26abedb Functions may not be optimized and we would like to know in cpu profiler what was the reason. 
Current v8 implementation may disable optimization for a particular function or block it with help of dont_optimize flag.
The patch propagates the reason of that to the SharedFunctionInfo where cpu profiler can get it.

SharedFunctionInfo is a heap object so I extracted 8 bits from OptsCount for handling bailout reason code.

1083d1f817 Remove deprecated profiler API 
This change removes --prof-lazy command line flag that was introduced for the old CPU profiler implementation in Chrome DevTools. DevTools now use profiler API defined in v8-profiler.h

This change also removes methods for pausing resuming --prof profiler. These methods were deprecated in v.3.20 (https://code.google.com/p/v8/source/browse/branches/3.20/include/v8.h#4629)

After this change the profiler will always start if --prof option is passed and can be stopped either in the tests or if write to log file fails.

From now on the v8config.h header should be the one and

compiler or certain compiler features. Since we need that
both internally and for the public API, the new v8config.h
is the proper place to add (everything is prefixed with V8_

85d8178d87 Deprecate self and total time getters and total sample count getter on CpuProfileNode 
All of these values are derived from the self samples count and there is no need to evaluate them in v8 when clients can do that when needed on their side.

Also added unsigned GetHitCount() which should be used instead of double GetSelfSamplesCount(). I'm going to deprecate the latter one once Blink has switched to GetHitCount.

e53471dbaa Remove elements transitions from the transition array. 
This is preparatory work for reordering the transition tree. Since elements transitions will be at the root of the transition tree, runtime access to them is slow since we have to walk the transition tree backwards first. Hence remove the optimization that promoted them to a special field, requiring a pointer (mostly NULL) in every non-simple transition array.

In order to properly sanitize exception data during a 'window.onerror'

headers at the time it was loaded into V8. This patch adds a single bool
to ScriptOrigin, and pipes that through the compiler to land on the
Script object. We can then retrieve the parameter when calling the
embedder's exception callback.

a0140093ba CPUProfiler: propagate scriptId to the front-end 
Each CpuProfileNode has resource_name string property.
It cost us N * strlen(resource_name) where N is number of functions in the collected profile.
We could transfer script_id instead of resource_name so it would reduce transfer
size and help us to solve the problem with evals and sourceURL.

This makes sure that the same symbols are present, independent of which
defines have been used while building V8. Otherwise only embedders with

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.

515aec2014 Transforming PersistentHandleVisitor to not need to copy Persistent handles. 
This gets rid of more places where Persistent handles are copied
(see crbug.com/236290 ).

Transition plan: after this CL, Blink will be modified to work both with and
without the #define, then the #define will be removed from V8.

The corresponding Blink side changes are in https://codereview.chromium.org/15670010/ .

9974d932b2 Deprecate profiler methods that accept security origin 
Now that the only known client console.profiles was removed from Blink:
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.

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).

cfe3e039ca Don't use anonymous types declared in an anonymous union. 
They are a non-standard extension (probably in C1X, IIRC), but clang is unhappy
with them when -Wnested-anon-types is enabled, which seems to be implied by
-pedantic.

With this change and the previous fix for clang, we are now -Werror clean, even
on clang 3.3.

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.

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.)

061f523b5a Change cctest/test-lockers to not copy persistent handles around. 
Instead, create Local handles to pass them around. This also means that the
code needs to be shifted around a bit such that a handle scope exists when
creating threads.

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.

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.

Two new methods are added to allow embedders to determine that execution
should be resumed at a particular point in the stack without being forced
to unwind all JS frames.

* V8::CancelTerminateExecution() -- When execution is terminated via a call
  to V8::TerminateExecution(), this method can be called to clear the
  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.

764e1a0fcf 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.

55f93b5532 Renamed "symbols" to "internalized strings" throughout the code base, 
in preparation of the introduction of ES6 'symbols' (aka private/unique names).

The SymbolTable became the StringTable. I also made sure to adapt all comments. The only remaining use of the term "symbol" (other than unrelated uses in the parser and such) is now 'NewSymbol' in the API and the 'V8.KeyedLoadGenericSymbol' counter, changing which might break embedders.

The one functional change in this CL is that I removed the former 'empty_string' constant, since it is redundant given the 'empty_symbol' constant that we also had (and both were used inconsistently).

be8e8f7528 Improve the JitCodeEventHandler API to add support for line position information. 
This includes:

* adding the CODE_ADD_LINE_POS_INFO, CODE_START_LINE_INFO_RECORDING, CODE_END_LINE_INFO_RECORDING event and the corresponding functionality.
 * adding the JITCodeLineInfo struct to record the code line info. I added this definition because Danno mentioned that "we'd like to cleanup and decouple the external debugging functionality"
 * some other small changes.

fab9a39d9d Make the Isolate parameter mandatory in Locker and Unlocker classes. 
Note that leaving out the Isolate parameter previously had a very special
meaning, namely "use the *default* Isolate", i.e. the one magically created at
program initialization time. All other API entries use the meaning "current
Isolate", which is different in a multi-threaded setting and confusing.

1ac3949a93 Removed deprecated functions from v8's external API. 
Removed the following deprecated functions:

   * Object::GetPointerFromInternalField
   * Object::SetPointerInInternalField
   * External::Wrap
   * External::Unwrap
   * Context::GetData
   * Context::SetData

They have been deprecated in the 3.15 branch and are not used by Chrome anymore.
Furthermore, judging from bug reports and email threads, embedders like node.js
and others are already using 3.15, too. All removed API entries can be emulated
by a one-liner, so adapting should not be hard for anybody.

We want to introduce more deprecations soon, but to keep things simple and avoid
having old and not-so-old deprecations in v8.h, the 3.15 deprecations are now
removed.

In general, the strategy of keeping deprecated things for one stable release and
then removing them seems to be a good compromise between a maintenance nightmare
and annoying external embedders. :-)

529f801fde Adapt Danno's Track Allocation Info idea to fast literals. When allocating a literal array, 
we store an AllocationSiteInfo object right after the JSArray, with a pointer to the
boilerplate object. Later, if the array transitions we check for the continued existence
of the temporary AllocationSiteInfo object (has no roots). If found, we'll use it to
transition the boilerplate array as well.

4cd41edcd9 Add methods to allow resuming execution after calling TerminateExecution(). 
Two new methods are added to allow embedders to determine that execution
should be resumed at a particular point in the stack without being forced
to unwind all JS frames.

* V8::ResumeExecution() -- When execution is terminated via a call to
  V8::TerminateExecution(), this method can be called to clear the
  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.

cec0745aa2 Introduce callback for resolving global object name while taking heap snapshot 
Heap profiler currently gets "document" of global objects while taking snapshot (to later retrieve its "URL"). This is unsafe as there may be no current v8 context when the property is requested while corresponding property accessor may make some assumptions about the context stack during its invokation. Several crashes were reported due to this problem:
https://bugs.webkit.org/show_bug.cgi?id=103076

c54fc70f13 Store Object.observe state per-isolate rather than per-context 
This requires adding a new JSObject to the strong root list and populating it from
object-observe.js. The main other change is that we now directly use ObjectHashTable
from JS rather than using WeakMap, since using the latter would end up leaking whichever
Context initialized that observation state.

Added a test via the API showing that different contexts all end up working on the same state.

37759f4d64 Implement committed physical memory stats for Linux. 
The patch introduces CommittedPhysicalMemory function to
the Heap class that reports committed *physical* memory acquired
for the heap from the OS.
It is important because some OSes may defer actual committment on e.g.
first access to the region.
So reporting just plain committed size led to various weird artifacts
like showing V8 allocated memory higher than the whole process
private size.
