f6d1a4fef1 Allow externalizing strings in old pointer space. 
This is what I think is a better solution to the "external strings in
old pointer space" problem. Basically, it is an issue because GC scans
all fields of objects in old pointer space and if the cached address
of the backing store is unaligned, it looks like a heap object, boom.

The solution here is to use short external strings when we externalize
a string in old pointer space, and when the address is unaligned.
Short external strings don't cache the address, so GC has no issues.

23cbf27e12 Tests for (pre)parse errors when "yield" is found in inappropriate places. 
In addition:
- Fix: PreParser used to report an unexpected token one token too late when
ParsePrimaryExpression failed.
- Unified identifier handling (PreParser::GetIdentifier is now like Parser::GetIdentifier).
- Fix: PreParser used to produce "unexpected_token YIELD" errors when Parser
produced "unexpected_token_identifier"; fixed PreParser to match Parser.

443e645a2d Tests and fixes for (pre)parse errors related to strict reserved words. 
This contains the following fixes:

- We had strict_reserved_word and unexpected_strict_reserved, which one to use
was totally mixed in Parser and PreParser. Removed strict_reserved_word.
- When we saw a strict future reserved word when expecting something completely
different (such as "(" in "function foo interface"), Parser reports unexpected
identifier, whereas PreParser used to report unexpected strict reserved
word. Fixed PreParser to report unexpected identifier too.
- Unified parser and preparser error locations when the name of a function is a
strict reserved word. Now both point to the name.

==========================

This is identical to the previous CL
   https://codereview.chromium.org/40133004/
with two differences:
 * Added a dummy implementation of String.prototype.normalize to be used when v8 is compiled without intl support
 * Rebased the the test files for webkit. That was the only reason for the previous failure (and revert).

51107bad1c Skip webkit/function-apply-aliased.js when running on simulators. 
The webkit/function-apply-aliased.js test fails on simulators (both MIPS
and ARM) as the printed output does not match to the expected. The
failing test forces a stack overflow exception and the ToString()
operation of the exception object fails because of an other stack
overflow and returns an empty string.

The problem is that on hardware a common JS and C stack is used so the
stack overflow can be caught in C functions also while on simulator
separated JS and C stacks are used.

This patch adds a "sim" condition to test .status files to skip tests
only on simulator.

99ce5a2484 The current 
version is passing all the existing test + a bunch of new tests
(packaged in the change list, too).

The patch extends the SlotRef object to describe captured and duplicated
objects. Since the SlotRefs are not independent of each other anymore,
there is a new SlotRefValueBuilder class that stores the SlotRefs and
later materializes the objects from the SlotRefs.

Note that unlike the previous implementation of SlotRefs, we now build
the SlotRef entries for the entire frame, not just the particular
function.  This is because duplicate objects might refer to previous
captured objects (that might live inside other inlined function's part
of the frame).

We also need to store the materialized objects between other potential
invocations of the same arguments object so that we materialize each
captured object at most once.  The materialized objects of frames live
in the new MaterielizedObjectStore object (contained in Isolate),
indexed by the frame's FP address.  Each argument materialization (and
deoptimization) tries to lookup its captured objects in the store before
building new ones.  Deoptimization also removes the materialized objects
from the store. We also schedule a lazy deopt to be sure that we always
get rid of the materialized objects and that the optmized function
adopts the materialized objects (instead of happily computing with its
captured representations).

Concerns:

- Is the FP address the right key for a frame? (Note that deoptimizer's
representation of frame is different from the argument object
materializer's one - it is not easy to find common ground.)

- Performance is suboptimal in several places, but a quick local run of
benchmarks does not seem to show a perf hit. Examples of possible
improvements: smarter generation of SlotRefs (build other functions'
SlotRefs only for captured objects and only if necessary), smarter
lookup of stored materialized objects.

- Ideally, we would like to share the code for argument materialization
with deoptimizer's materializer.  However, the supporting data structures
(mainly the frame descriptor) are quite different in each case, so it
looks more like a separate project.

Thanks for any feedback.

868ad01ecb This is a preview of the captured arguments object materialization, 
mostly to make sure that it is going in the right direction. The current
version is passing all the existing test + a bunch of new tests
(packaged in the change list, too).

The patch extends the SlotRef object to describe captured and duplicated
objects. Since the SlotRefs are not independent of each other anymore,
there is a new SlotRefValueBuilder class that stores the SlotRefs and

indexed by the frame's FP address.  Each argument materialization (and
deoptimization) tries to lookup its captured objects in the store before

from the store. We also schedule a lazy deopt to be sure that we always
get rid of the materialized objects and that the optmized function
adopts the materialized objects (instead of happily computing with its
captured representations).

Concerns:

- Is there a simpler/more correct way to store the already-materialized
objects? (At the moment there is a custom root reference to JSArray
containing frames' FixedArrays with their captured objects.)

- Is the FP address the right key for a frame? (Note that deoptimizer's
representation of frame is different from the argument object
materializer's one - it is not easy to find common ground.)

- Performance is suboptimal in several places, but a quick local run of

371d6f6a98 We shouldn't throw under FLAG_debug_code, rather abort. 
Throwing under FLAG_debug_code confuses the rest of our infrastructure
which expects a safe point at the site of call into the runtime
for throw. We were doing that to make a clusterfuzz test happy, but
the better solution is to assert/abort under debug_code, and prevent
clusterfuzz from fuzzing on internal APIs that crash on incorrect
values.

We'll need to alter the fuzzer to turn off fuzzing for:

string-natives.js
lithium/SeqStringSetChar.js
regress/regress-seqstrsetchar-ex3.js
regress/regress-seqstrsetchar-ex1.js
regress/regress-crbug-320922.js

So as to prevent the fuzzer from running
%_OneByteSeqStringSetChar() and
%_TwoByteSeqStringSetChar().

b4949cfd62 Fixed floor-of-div optimization. 
We removed an HDiv by hand which was still used by an HChange. The
solution is letting dead code removal do the cleanup.

Removed a fragile "optimization" (looking through an HChange), too,
this obviously never triggered and is hard to get right given all our
global invariants and state/type/... changes.

The repro is a bit tricky, because you need inlining to make our
representations and types disagree in this case.

155ef100e9 Fix logic error in assert in IsUndeclaredGlobal() 
Recent changes in IC logic meant that CallStubs no longer use the Contextual bit. IsUndeclaredGlobal() needed to adjust for that.

In fact, now the CL has morphed to remove the notion of storing contextual state in the IC at all, it just becomes some extra ic state of the load ic. This took some adjustment in harmony code to use the global receiver for certain stores.

Now it's clearer that only LoadICs actually record any information about contextual or not.

7cee52948f Fix stub-invoked setter callback handling. 
When invoking a setter callback for a property using
JSObject::SetPropertyWithCallback(),the callback arguments includes
a correct pair of receiver and holder objects.

Such a pair of _possibly different_ arguments (receiver, holder) must
also be supplied when invoking the same setter callback from JITed
code, when the setter is invoked through the StoreCallbackProperty
stub.

An example where this matters are the accessor properties kept on the
global scope of Worker (i.e., properties kept on the global object
itself, and not on its prototype.) Conflating the receiver with the
holder leads to general confusion when attempting to fetch out the
wrapper object.

then we revive the cell by marking it. Otherwise, the cell value is dead, so

acf24331e3 Fixed Lithium environment generation bug for captured objects (created 
by escape analysis). Added several tests that expose the bug.

Summary:
LCodegen::AddToTranslation assumes that Lithium environments are
generated by depth-first traversal, but LChunkBuilder::CreateEnvironment
was generating them in breadth-first fashion. This fixes the
CreateEnvironment to traverse the captured objects depth-first.

Note:
It might be worth considering representing LEnvironment by a list
with the same order as the serialized translation representation
rather than having two lists with a subtle relationship between
them (and then serialize in a slightly different order again).

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.

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.

d9e0763532 Track *all* external strings in the external string table. 
Up till now, external strings may be tracked in the string table
(for internalized strings) or the external string table, depending
on in which order internalize and externalize happened.

The internalized string table should not have to deal with external
strings, all of which should be tracked by the external string table.

cd5ea74700 Replace 'operator*' with explicit 'get' method on SmartPointer 
Made operator* return reference to the raw type, not pointer. New method 'get()' should be used when raw pointer is needed.

Also removed useless inline modifier from the SmaprtPointer methods and added const modifier to the methods that don't change smart pointer.

Made ~SmartPointerBase protected to avoid accidental calls of the non-virtual base class's destructor.

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.

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.
