d22b125a0c Document --module option for d8
- I think d8's ability to load es6 modules is important enough to
document through the CLI
- I also tried to simplify the d8/shell CLI synopsis

This is my first patch; I can't run the automated test suite.

1c23f888a1 Cleanup NewFunctionFromSharedFunctionInfo
NewFunctionFromSharedFunctionInfo is not called with `undefined`
anymore, and so can be changed to just accept `Handle<Context>`.

Additionally, reporting script compilation to the debugger can now
be moved into `Compiler::PostInstantiation`.

1dcd1c9f35 Report late-bound scripts to the debugger
Previously, if an unbound script was created in a non-inspected context,
but later bound to an inspected one, it never appeared in the
debugger sources.

After this change `OnAfterCompile` will be invoked not on the original
script compilation, but when it's actually bound to a context for
execution, which means `Debugger.scriptParsed` will be now sent to the
inspector even for such precompiled scripts.

ada64b58bf interpreter: make interpreted frames distinguishable in the native stack
Before Turbofan/Ignition it was possible to use external profilers to
sample running V8/Node.js processes and generate reports/FlameGraphs
from that. It's still possible to do so, but non-optimized JavaScript
functions appear in the stack as InterpreterEntryTrampoline. This commit
adds a runtime flag which makes interpreted frames visible on the
process' native stack as distinguishable functions, making the sampled
data gathered by external profilers such as Linux perf and DTrace more
useful.

09b53eef4c [api] Make running scripts in AddMessageListener callback work in debug mode
The existance of an `AllowJavascriptExecutionDebugOnly` scope in
`Isolate::ReportPendingMessages()` indicates that the API supports
running arbitrary JS code in a `AddMessageListener` callback.

Currently, this can fail in debug mode: The
`!isolate->external_caught_exception()` condition is checked when
entering API methods inside such a handler. However, if there is
a verbose `TryCatch` active when the exception occurs, this
check fails, and when calling `ToString()` on the exception object
leaves a pending exception itself, the flag is re-set to `true`.

Fix this problem by clearing the flag and the pending exception if
there was one during `ToString()`. This matches the code a few lines
up in `messages.cc`, so the exception state is now consistent
during the callback.

This currently makes a Node.js test fail in debug mode
(`parallel/test-error-reporting`).

metadata. I96a8a7cdded6f7c37b6f1da659d63df9e3a5de2b moved
the Code class to a new file without updating the postmortem
jobs. This resulted in some constants used by Node.js to
disappear, leading to build failures on SmartOS.

end of input and parse error:

  if (token_ == kEndOfInput || token_ == kParseError) {

but until now the code in the parsing loop only checked
for `kEndOfInput`, resulting in an infinite loop on

fe598532ec Pass Isolate pointer to String::Utf8Value/Value constructors
As part of J2V8 development (https://github.com/eclipsesource/J2V8),
we realized that we had a subtle bug in how Isolate scope was created
and it's lifetime managed, see:
https://github.com/eclipsesource/J2V8/issues/313.

Mentioned above bug was fixed, however, what we also noticed is that
V8 API has been constantly and slowly moving to such an API, in which
one has to pass Isolate explicitly to methods and/or constructors. We
found two more places that might have been overlooked. This contribution
adds passing of Isolate pointer explicitly to constructors of
String::Utf8Value and String::Value classes.

3bef2af6ef [build] Set MSVS .obj folders in gyp for v8_base
Building on Windows with gyp fails depending on the result from
sharding the src/v8.gyp:v8_base target. If two source files with the
same name are in the same shard, their output object file path would
conflict with one another. One example of this conflict is v8_base's
runtime/runtime.cc and the V8 inspector's protocol/Runtime.cpp that
is generated at build time, for which the files runtime.obj and
Runtime.obj would be created, but MSVS overwrites one of them with
the other.

Dividing the .obj output path by the original source's extension
prevents this overwrite.

2f6be682ac Parser: Report use counts once per feature
Reporting use counts by invoking a callback once per occurrence has
a large overhead cost in certain situations, for example when it needs
to be dispatched to a different thread (which is the case for Web Workers).

Parsing large scripts can produce a lot of occurrences (strict/sloppy mode
once per function).

Chromium (the only known user of UseCounters so far) does not actually care
about number of occurrences, but simply whether they happened at least once.
This commit changes behavior to report features at most once, which dramatically
improves performance for impacted use cases, and should not affect the only
known real world usage.

b6c9b70356 Make handle ctors explicit
Without this change, the v8::Local<> constructor will be picked up by the
compiler as an option for an implicit cast for any pointer type.  This leads
to bad error messages when accidentally passing an erroneous pointer type to
a function wanting a Local<> (complains about a pointer assignment in Local<>'s
constructor as opposed to a bad type for the parameter of the function being
called) and also causes ambiguity errors where none should exist when calling
overloaded functions (for example a function taking either a std::string or a
v8::Local<v8::Script> cannot be called with a const char * because the compiler
sees both types as being constructable with a const char *).

aeb8073c4a Add Isolate::DiscardThreadSpecificMetadata method to embedder API.
If many threads use the same Isolate (or many Isolates) and then
terminate, their PerIsolateThreadData objects are never cleaned
up, resulting in a slow memory leak and, worse, the
PerIsolateThreadData chain getting larger and larger, adversely
affecting performance.

In this situation, embedders will now be encouraged to apply
DiscardThreadSpecificMetadata against any Isolate a thread is
done with, especially if the thread is about to terminate.

Note that it is harmless to run DiscardThreadSpecificMetadata
against an Isolate for which a thread has no thread data and
per-Isolate thread data can be reestablished if a thread starts
using an Isolate again after running DiscardThreadSpecificMetadata
against it.

It is, however, an embedder error to run
DiscardThreadSpecificMetadata against an Isolate in thread with a
Locker for the Isolate in the stack or against an Entered Isolate.

This change cannot cause any change in behavior in existing apps
as the only added coded can only be reached via the new
DiscardThreadSpecificMetadata method.

8ed0454332 Emit better error message about writable properties
Section 8.10.5 9a specifies that a property descriptor cannot both have
accessors and specify the writability of the property. The previous
error message was misleading because it referred to writable rather
than specifying the writability (which includes writable: false).

ab9898980e Don’t smash globals used by the test helper itself.
Since https://codereview.chromium.org/366103005 the promise tests null out
various globals, to ensure the promise implementation doesn’t itself rely
on functions patchable by monkeys.

Unfortunately, doing so breaks test assertion failures which rely on
those globals.

This isn’t the ideal solution, but does improve the current state.

ddb5c2d999 Make NumberFormat use the ICU currency data, fix bug in NumberFormat
NumberFormat previously just used a min of 0 digits after the decimal and a max of 3. This CL changes it so that we use the ICU currency data, and set the min and max to the number of numbers after the decimal point for each currency.

This CL also fixes a small bug where if the minimum fraction digits is above 3 but the maximum fraction digits isn't set, then it returns with only three numbers after the decimal point.

3badfdcd50 Re-write duplicated assertions
The modified assertions targeted the property descriptor for the
template object's first "cooked" value. The code immediately preceeding
these statements asserts these values.

Update the assertions to instead target the property descriptor for the
template object's first "raw" value (which are otherwise untested).

edit1: adding jochen to reviewers since he was assigned through the issue tracker and danno since he seems to do a fair amount of cross-platform work

531f7ab1d2 [turbofan] Better narrow the derived type for the right shift operation.
Currently the derived type of a right shift does not narrow the input
type based on the actual shift amount - well it does some narrowing
but more can be down. For patterns such as u32[i>>2], which is very
common is asm.js code, this limits the ability to later prove that an
index bounds check is unnecessary which can have a significant
performance impact.

Notes:
- All the added authors have signed the CLA.
- Updated 2 AUTHORS lines to match the e-mail addresses used for signing the CLA.
- In addition, checked that all authors in the AUTHORS file after this change
  have signed the CLA.
- Whenever it was possible to guess, based on the e-mail address, that the
  contribution was made under a corporate CLA, added the company and the
  wildcard instead of the individual.

  authors). Domains affected by this change: intel.com, arm.com, codeaurora.org.

In addition, added a wildcard rule for Chromium (which was not previously

a4c072ed47 Fix a crash when generating forward jumps to labels at very high assembly offsets
The first jump to a specific label was marked as jump to absolute
position -4. This value was stored in the assembly as a branch to a
offset (-4 - (instruction offset + 8)). The offset is only 24 bit
long on ARM. Thus instruction offsets higher than 2^23 - 12 would overflow
the offset.

Fix by denoting the first jump to a label by storing the jump
instruction location as the target. This will result in offset of -8,
which of course always fits in the branch instruction.

53adf3b19c 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::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.
