e3fa6d67ca Avoid duplication of a hidden & inherited prototype's properties. 
In Runtime_GetLocalPropertyNames(), the hidden prototypes of an object
are also consulted when deriving the property name set. However, if
given a function object and its template was inherited from the
template of one of its hidden prototypes, that hidden prototype's
property accessors will be present on the object already. Unwanted
duplicates will therefore appear.

Hence, go through the property names that the hidden prototypes
contribute and remove any already occurring ones.

Assumed to be a rare constellation, so the cost of this extra pass is
considered acceptable.

7ac7a7ea99 Fix a race between concurrent recompilation and OSR. 
If concurrent recompilation finishes before OSR, then OSR replaces
the old optimized code without evicting it from the optimized code map.

New functions can get the old optimized code from the optimized code map,
but the old code could be already deoptimized.

2a4be7067c Refactor the compiling pipeline. 
Goals:
 - easier to read, more suitable identifiers.
 - better distinction between compiling optimized/unoptimized code
 - compiler does not install code on the function.
 - easier to add features (e.g. caching optimized code for osr).
 - remove unnecessary code.

79ad8bf2e0 Fix sporadic crash in the RequestInterruptTestWithNativeAccessor. 
The test was broken. V8 currently does not correctly lookup NativeDataProperty accessors attached to the PrototypeTemplate of FunctionTemplate (Issue 3066). As the result while(obj.shouldContinue) loop was immediately exiting and the test would terminate while RequestInterruptTestBase::InterruptThread would be still starting up. As the result later InterruptThread would try to access members of the test object which was destroyed.

The test was fixed:

- instead of attaching accessor to PrototypeTemplate we attach it to  InstanceTemplate;
- an assertion was added to verify that we completed the test successfully due to interruptor firing not due to sporadic loop termination due to some unrelated bug.

The flag has been on in the build for ~9 months, and we aren't likely to turn it off. The only customer of the flag is a set of tests that want to verify transitioning behavior in isolation. This CL removes the flag and updates those tests to get what they want without the flag.

e6ef64c590 [platform] Implement a worker pool 
We don't use the worker pool yet, however, there are tests. Yay. The
next step is to use the worker pool for parallel sweeping.

I've also started to move the platform related files into a sub
directory. The goal is to eventually build all the platform stuff as
a separate library which is used by d8 and cctest (and other embedders
that wish to use the default implementation) but not by chromium.

bc77d4d60a Reland r18363. 
Introduce API to temporarily interrupt long running JavaScript code.

It is different from termination API as interrupted JavaScript will continue to execute normally when registered InterruptCallback returns.

  /**
   * Request V8 to interrupt long running JavaScript code and invoke
   * the given |callback| passing the given |data| to it. After |callback|
   * returns control will be returned to the JavaScript code.
   * At any given moment V8 can remember only a single callback for the very
   * last interrupt request.
   * Can be called from another thread without acquiring a |Locker|.
   * Registered |callback| must not reenter interrupted Isolate.
   */
  void RequestInterrupt(InterruptCallback callback, void* data);

  /**
   * Clear interrupt request created by |RequestInterrupt|.
   * Can be called from another thread without acquiring a |Locker|.
   */
  void ClearInterrupt();

Fix Hydrogen SCE pass to avoid eliminating stack guards too aggressively. Only normal JavaScript functions are guaranteed to have stack guard in the prologue. If function is a builtin or has a custom call IC it will lack one.

Changes from r18363:

- includes r18364 to fix compilation errors: removes debugging only code;

- makes interrupiton related tests not threaded, because they rely on having exclusive access to the V8 instance and the fact that they can only interrupt themselves, if they are interrupted from the outside they break;

- changes HasStackCheck predicate used during SCE pass to avoid handles dereference to make SCE compatible with parallel recompilation.

5567426483 Do not put allocated block into HeapObjectsMap 
Heap allocation reported to AllocationTracker may be later divided into several objects so it is incorrect to put the block as a new HeapObject into the map. We will match allocated block with actual HeapObjects later when iterating Heap (will be addressed in another patch). Since the objects are not assigned an id immediately after creation we need to call FindOrAddEntry when finding id for SharedFunctionInfo during stack crawling.

Removed hooks for tracking creation of AllocationMemento. AllocationMemento is not a HeapObject and should be considered as implementation overhead.

Renamed NewObjectEvent to AllocationEvent which is more precise in case of folded allocations and when a part of the new block becomes AllocationMemento.

e943623b12 Harmony promises 
Based on prototype at

  https://github.com/rossberg-chromium/js-promise

which informed the latest spec draft version at

  https://github.com/domenic/promises-unwrapping/blob/master/README.md

Activated by --harmony-promises.

Feature complete with respect to the draft spec, plus the addition of .when and .deferred methods. Final naming and other possible deviations from the current draft will hopefully be resolved soon after the next TC39 meeting.

This CL also generalises the Object.observe delivery loop into a simplistic microtask loop. Currently, all observer events are delivered before invoking any promise handler in a single fixpoint iteration. It's not clear yet what the final semantics is supposed to be (should there be a global event ordering?), but it will probably require a more thorough event loop abstraction inside V8 once we get there.

f3a22f965e The goal is to discover the appropriate heap space for objects created in full 
code. By the time we optimize the code, we'll be able to decide on new or old
space based on the number of surviving objects after one or more gcs.

The mechanism is a "memento" placed behind objects in the heap. It's currently
done for array and object literals, with plans to use mementos for constructed
objects as well (in a later CL).

The feature is behind the flag allocation_site_pretenuring, currently off.

e6e8acd446 Make test runner more flexible for running fast tests. 
Transformed variant flags into named variants. Now, all combinations of variants can be specified on the command line. The old command-line flags are kept for backwards compatibility on the bots.

Added two new test groups: slow and pass|fail. Both are implemented similar to the flaky test feature and allow to either skip or run tests marked as slow or as pass|fail.

81b22bbf96 A performance regression in array literal creation was caused by refactoring that eliminated a special fast case for shallow arrays. At the same time the general case got a bit slower. This CL restores most of the performance without coding the special fast case. The virtual dispatching is unnecessary because we know what we want to do at compile time. A flag was added to Runtime::CreateArrayLiteral. The flags delivers information about shallowness but also whether or not allocation mementos should be created. This is useful for crankshafted code.

2b1da67263 Implement Math.random() purely in JavaScript. 
This removes tons of architecture-specific code and makes it easy to
experiment with other pseudo-RNG algorithms. The crankshafted code is
extremely good, keeping all things unboxed and doing only minimal
checks, so it is basically equivalent to the handwritten code.

When benchmarks are run without parallel recompilation, we get a few
percent regression on SunSpider's string-validate-input and
string-base64, but these benchmarks run so fast that the overall
SunSpider score is hardly affected and within the usual jitter. Note
that these benchmarks actually run even faster when we don't
crankshaft at all on the main thread (the regression is not caused by
bad code, it is caused by Crankshaft needing a few hundred microsecond
for compilation of a trivial function). Luckily, when parallel
recompilation is enabled, i.e. in the browser, we see no regression at
all!

c7b1b79e4d This is the exact copy of r17365 which was reverted in r17488 due to memory corruption. The root cause for the memory corruption - missing check for bump pointer limit before storing filler map must be addressed in r17626 where allocation hooks were removed from the generated code and left only in the runtime. 
This is initial implementation of allocation profiler.

Whenever new object allocation is reported to the HeapProfiler and allocation tracking is on we will capture current stack trace, add it to the collection of the allocation traces (a tree) and attribute the allocated size to the top JS function on the stack.

Format of serialized heap snapshot is extended to include information about recorded allocation stack traces.

This patch is r17301 plus a fix for the test crash in debug mode. The test crashed because we were traversing stack trace when just allocated object wasn't completely configured, in particular the map pointer was incorrect. Invalid Map pointer broke heap iteration required to find Code object for a given pc during stack traversal. The solution is to insert free space filler in the newly allocated block just before collecting stack trace.

3cf157b43b Inline zero argument array constructor. 
patch from issue 54583003 (dependent code).

Zero arguments - very easy

1 argument - three special cases:
  a) If length is a constant in valid array length range,
     no need to check it at runtime.
  b) respect DoNotInline feedback on the AllocationSite for
     cases that the argument is not a smi or is an integer
     with a length that should create a dictionary.
  c) if kind feedback is non-holey, and length is non-constant,
     we'd have to generate a lot of code to be correct.
     Don't inline this case.

N arguments - one special case:
  a) If a deopt ever occurs because an input argument isn't
     compatible with the elements kind, then set the
     DoNotInline flag.

cec8383cff Provide private symbols through internal APIs 
Adds a notion of private symbols, mainly intended for internal use, especially, self-hosting of built-in types that would otherwise require new C++ classes.

On the JS side (i.e., in built-ins), private properties can be created and accessed through a set of macros:

  NEW_PRIVATE(print_name)
  HAS_PRIVATE(obj, sym)
  GET_PRIVATE(obj, sym)
  SET_PRIVATE(obj, sym, val)
  DELETE_PRIVATE(obj, sym)

In the V8 API, they are accessible via a new class Private, and respective HasPrivate/Get/Private/SetPrivate/DeletePrivate methods on calss Object.

These APIs are designed and restricted such that their implementation can later be replaced by whatever ES7+ will officially provide.
