70079dab13 Add basic compilation support for modules
This adds an "experimental" API hook (v8::ScriptCompiler::CompileModule)
allowing compilation of modules. The code gen is incredibly basic: the
module body is represented by a Block in the AST. But this at least gets
more of the pipeline working, and opens the door to writing mjsunit tests
(once d8 is modified to support module compilation).

16843e239d Megamorphic KeyedLoadIC needs special handling for vector ics.
When --vector-ics is true, we still tail-call to the hand-written
megamorphic KeyedLoadIC (formerly "generic"). Now that this code uses
the megamorphic cache, it needs to deal properly with the vector and
slot registers. Achieve this with a sentinel vectors/slot combo.

f1ba8d8f86 Contribution of PowerPC port (continuation of 422063005) - AIX Common1
Contribution of PowerPC port (continuation of 422063005 and 817143002). This patch covers
the key changes needed to the common files needed to support AIX. Subsequent
patches will cover:
- changes to update the ppc directories so they are current with the changes
in the rest of the project.
- remaining AIX changes not resolved by 4.8 compiler
- individual optimizations for PPC

This is based off of the GitHub repository

87e4bba31e Support multiple interrupt requests in v8 API.
There might be a number of clients that would like to
setup an interrupt request on the Isolate.

The patch also deprecates ClearInterrupt API. As long as
the interrupt handler is called outside of locks there's no way
to guarantee that the handler will not be called after
ClearInterrupt was invoked as it might have already started execution.

643c24eb95 Set V8_CC_GNU or V8_CC_MSVC for clang in gcc / cl mode.
Also, remove V8_CC_CLANG since it's not read anywhere (and ideally shouldn't
be).

Clang tries to be compatible with gcc in clang mode, and with msvc in clang-cl
mode. It wants to go down the same code paths that these compilers want to go
down in most cases.

For example, V8PRIxPTR was set incorrectly on Windows 64-bit before this change
since macros.h assumed that checking for V8_CC_MSVC is enough to find LLP64
systems, but V8_CC_MSVC wasn't set for clang.  Most other existing checks for
V8_CC_MSVC should be taken for clang-cl too (and for the remaining ones,
clang-cl is happy with either code path).

Likewise, V8_IMMEDIATE_CRASH is currently set to a suboptimal value with clang
since __builtin_trap() is only used if V8_CC_GNU is set.

Including clang in the gcc and cl macros is also what chromium does.

1a64b02dcf harmony_scoping: Implement lexical bindings at top level
This implements correct semantics for "extensible" top level lexical scope.
The entire lexical scope is represented at runtime by GlobalContextTable, reachable from native context and accumulating global contexts from every script loaded into the context.

When the new script starts executing, it does the following validation:
- checks the GlobalContextTable and global object (non-configurable own) properties against the set of declarations it introduces and reports potential conflicts.
- invalidates the conflicting PropertyCells on global object, so that any code depending on them will miss/deopt causing any contextual lookups to be reexecuted under the new bindings
- adds the lexical bindings it introduces to the GlobalContextTable

Loads and stores for contextual lookups are modified so that they check the GlobalContextTable before looking up properties on global object, thus implementing the shadowing of global object properties by lexical declarations.

d56a21ebff The idea behind of this solution is to use the existing "relocation info" instead of consumption the CodeLinePosition events emitted by the V8 compilers.
During generation code and relocation info are generated simultaneously.
When code generation is done you each code object has associated "relocation info".
Relocation information lets V8 to mark interesting places in the generated code: the pointers that might need to be relocated (after garbage collection),
correspondences between the machine program counter and source locations for stack walking.

This patch:
1. Add more source positions info in reloc info to make it suitable for source level mapping.
The amount of data should not be increased dramatically because (1) V8 already marks interesting places in the generated code and
(2) V8 does not write redundant information (it writes a pair (pc_offset, pos) only if pos is changed and skips other).
I measured it on Octane benchmark - for unoptimized code the number of source positions may achieve 2x ('lin_solve' from NavierStokes benchmark).

2. When a sample happens, CPU profiler finds a code object by pc, then use its reloc info to match the sample to a source line.
If a source line is found that hit counter is increased by one for this line.

3. Add a new public V8 API to get the hit source lines by CDT CPU profiler.
Note that it's expected a minor patch in Blink to pack the source level info in JSON to be shown.

4.Add a test that checks how the samples are distributed through source lines.
It tests two cases: (1) relocation info created during code generation and (2) relocation info associated with precompiled function's version.

6482fb3ee4 Extend CPU profiler with mapping ticks to source lines
The idea behind of this solution is to use the existing "relocation info" instead of consumption the CodeLinePosition events emitted by the V8 compilers.
During generation code and relocation info are generated simultaneously.
When code generation is done you each code object has associated "relocation info".
Relocation information lets V8 to mark interesting places in the generated code: the pointers that might need to be relocated (after garbage collection),
correspondences between the machine program counter and source locations for stack walking.

This patch:
1. Add more source positions info in reloc info to make it suitable for source level mapping.
The amount of data should not be increased dramatically because (1) V8 already marks interesting places in the generated code and
(2) V8 does not write redundant information (it writes a pair (pc_offset, pos) only if pos is changed and skips other).
I measured it on Octane benchmark - for unoptimized code the number of source positions may achieve 2x ('lin_solve' from NavierStokes benchmark).

2. When a sample happens, CPU profiler finds a code object by pc, then use its reloc info to match the sample to a source line.
If a source line is found that hit counter is increased by one for this line.

3. Add a new public V8 API to get the hit source lines by CDT CPU profiler.
Note that it's expected a minor patch in Blink to pack the source level info in JSON to be shown.

4.Add a test that checks how the samples are distributed through source lines.
It tests two cases: (1) relocation info created during code generation and (2) relocation info associated with precompiled function's version.

069a9c75ad Move configuration of ResourceConstraints to Isolate construction
We can only set resource constraints before the isolate is initialized.
Since in the future, we want to initialize isolates at construction
time, we need to set constraints there.

It's possible to later modify the stack limit, so introduce an
Isolate::SetStackLimit method for that.

The SetResourceConstraints method will be deprecated. Users should pass
ResourceConstraints to Isolate::New, and use Isolate::SetStackLimit to
later modify the stack limit.

65a1857824 Currently, a new isolate is created in an uninitialized state, and
several API methods will automatically initialize it. During this
uninitialized state, code event handlers and function entry handlers can
be attached to the isolate.

This CL deprecates SetFunctionEntryHook and moves the configuration of
those handlers to the Isolate factory method.

This will allow for initializing the Isolate at creation time in the
future.

Users of V8::SetFunctionEntryHook should pass the entry hook to
Isolate::New instead. V8::SetJitCodeEventHandler should either be passed
to Isolate::New as well, or (if startup events are not required) invoked
via the Isolate.

a42612b4a7 Change ScriptCompiler::CompileOptions to allow for two 'cache' modes
(parser or code) and to be explicit about cache consumption or production
(rather than making presence of cached_data imply one or the other.)

Also add a --cache flag to d8, to allow testing the functionality.

-----------------------------
API change

Reason: Currently, V8 supports a 'parser cache' for repeatedly executing the same script. We'd like to add a 2nd mode that would cache code, and would like to let the embedder decide which mode they chose (if any).

Note: Previously, the 'use cached data' property was implied by the presence of the cached data itself. (That is, kNoCompileOptions and source->cached_data != NULL.) That is no longer sufficient, since the presence of data is no longer sufficient to determine /which kind/ of data is present.

Changes from old behaviour:

- If you previously didn't use caching, nothing changes.
Example:
  v8::CompileUnbound(isolate, source, kNoCompileOptions);

- If you previously used caching, it worked like this:

  - 1st run:
  v8::CompileUnbound(isolate, source, kProduceToCache);
  Then, source->cached_data would contain the
  data-to-be cached. This remains the same, except you
  need to tell V8 which type of data you want.
  v8::CompileUnbound(isolate, source, kProduceParserCache);

  - 2nd run:
  v8::CompileUnbound(isolate, source, kNoCompileOptions);
  with source->cached_data set to the data you received in
  the first run. This will now ignore the cached data, and
  you need to explicitly tell V8 to use it:
  v8::CompileUnbound(isolate, source, kConsumeParserCache);

319e5226e9 fix the vtune support bug.
During https://code.google.com/p/v8/source/detail?r=19925 checkin context bound scripts (Script)
and context unbound scripts (UnboundScript) are Distinguished.

And then Sven Panne helped to fix the vtune support compilation
error in https://code.google.com/p/v8/source/detail?r=20955.

The problem is that there is runtime error for vtune
support.
In our original implementation, we encapsulated and passed v8::internal::Script
to V8 API. It will leads to type check error for current V8::Script definition.

So I changed the Handle<Script> definition in JitCodeEvent
to Handle<UnboundScript>
 and add the corresponding change in log.cc.

If you do NOT prefer to change in include/v8.h. I think I can change the definition of
CodeEventLogger::LogRecordedBuffer(...) so that the we can pass the correct
type (JSFunction) as V8::Script to V8 API.

initializing the respective isolate (and silently ignore them).

Esp. add a per-isolate API to set the stats counter callbacks and
make it possible to set the stats counter callback after the isolate
was touched.

Embedders should use e.g. isolate->SetCounterFunction(callback) instead
of v8::V8::SetCounterFunction(callback).

ba9f391bc0 Support external startup data in V8.
[Retry of crrev.com/293993021, which caused problems with 'ninja all' in Chromium. First patch set if a clean apply
of crrev.com/293993021. Subsequent sets are the actual fix
for that issue.]

If the embedder chooses, the 'natives' (library sources) and the
precompiled startup blob can be written to files during the build
process and handed over to V8 at startup. The main purpose would be
to reduce the size of the compiled binary for space constrained
platforms.

The build-time option is off by default. Nothing should change if
it's not enabled.

60a71d8a8c Remove PROHIBITS_OVERWRITING as it is subsumed by non-configurable properties.
v8::DontDelete is set for Unforgeable properties, so just not setting PROHIBITS_OVERWRITING should be enough.

The secondary "feature" of not allowing accessors to be installed in extending objects is incorrect and confusing, given that it only applies to accessors but not to regular properties:
Object.defineProperty({__proto__:window}, "location", { value: 10 })
works where
Object.defineProperty({__proto__:window}, "location", { get: function() {} })
doesn't work.

20eeff9ae4 Allow microtasks to throw exceptions and handle them gracefully
If the embedder calls V8::TerminateExecution while we're running microtasks, bail out
and clear any pending microtasks.

All other exceptions are simply swallowed. No current Blink or V8 microtasks throw, this
just ensures something sane happens if another embedder decides to pass a throwing
microtask (or if ours unexpectedly throw due to, e.g., stack exhaustion).

06086a90e0 Fix the "PersistentValueMap" memory leak reported here:
http://build.chromium.org/p/client.v8/builders/V8%20Linux64%20ASAN

The bug:
The code assumed that a weak Persistent whose weak callback is being
called would still be weak. That isn't true since the persistent is
un-weakened by the garbage collector before calling the weak callback. [1]

Specifically, PersistentValueMap would funnel all 'remove' actions
through its Release method, which uses PersistentBase::ClearWeak to
obtain the callback data. [2] For 'removes' caused by the weak callback,
ClearWeak always returns a NULL-pointer since by that time the weak
persistent was already un-weakend. The result was a memory leak in
the test, since the code to delete the weak callback data would
delete NULL.

The fix:
I explicity call Traits::DisposeCallbackData from the weak callback
with the data obtained from the v8::WeakCallbackData. To avoid invalid
calls to DisposeCallbackData, I also check whether this instance is
(still) weak before calling it. (That check could easily be elided
if it's expensive, for the price of having two 'remove' code paths.)

Severety:
Probably low. At least in Chromium, noone uses the API in a way to
trigger this; only the test does.
