v8 currently detects ABI by checking OS and endianness,
but this is not sufficient to properly detect cases in
which the ELFv2 ABI is used on big-endian Linux systems.
Update these checks to use additionally use the _CALL_ELF
macro in order to properly handle such cases.
This issue was initially discovered by the Adélie Linux team.

TurboAssemblerBase constructors were declared as public to make the inherited

The SourceRangeAstVisitor has custom logic for blocks ending with a
statement that has a continuation range. In these cases, the trailing
continuation is removed which makes the reported coverage ranges a bit
nicer.
throw Error('foo') consists of an ExpressionStatement, with a
Throw expression stored within the statement. The source range itself
is stored with the Throw, not the statement.
We now properly extract the correct AST node for trailing throw
statements.

The logic for removing while iterating is non-standard and
a left over from a previous index based loop. This patch
replaces it with a standard erase based version.
This fixes a runtime crash with MSVC that invalidates the
iterator and then asserts. This also makes the code safe
in case the last move can be redundant.

Add an enum argument to DateTimeConfigurationChangeNotification to
control whether or not to redetect the host time zone. The default value
kSkip doesn't cause redetecting so that callers do not need to change if
they want the current behavior (e.g. Chromium).
Note that the host time zone detection does not work when v8 is run
inside a sandbox as in Chromium so that Chromium detects the host time
zone outside the sandbox before calling
DateTimeConfigurationChangeNotification. OTOH, other v8 embedders may
find it more convenient for v8 to do the host time zone detection on
their behalf. In that case, they can call the function with the new
argument set to value kRedetect.
Test:
With PHP+V8Js on linux, execute:
php -r '
putenv("TZ=Europe/Helsinki");
$v8 = new V8Js();
$v8->executeString("print((new Date(0)).toString()+\"\\n\");");
putenv("TZ=America/New_York");

So far the return value was identical to the values iterator and that

This also adds tests to verify the results and improves the coverage

Currently, because the source float_64_array has an iterator, it hits
the code in the "check_iterator" section of TypedArrayFrom which calls
IterableToList. This builds a temporary PACKED_ELEMENTS array (and boxes
all of the numeric values as HeapNumbers), then uses this as the source
array.
This patch checks if the source array is a TypedArray, and if the iterator
is the built-in one (where we know the iterator's behaviour). If both are
true then it bypasses the creation of this temporary array and uses the
original TypedArray as the source.
This allows it to take advantage of the existing fast code for copying one
typed array to another.

I have a project that embeds V8 and uses a single `Isolate` from multiple
threads. The program runs just fine, but sometimes the inspector doesn't
stop on the correct line after stepping over a statement that switches
threads behind the scenes, even though the original thread is restored by
the time the next statement is executed.
After some digging, I discovered that the `Debug::ArchiveDebug` and
`Debug::RestoreDebug` methods, which should be responsible for
saving/restoring this `ThreadLocal` information when switching threads,
currently don't do anything.
This commit implements those methods using MemCopy, in the style of other
Archive/Restore methods in the V8 codebase.

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.

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.

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`).

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.

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.

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.

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 *).

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.

Instead of basing matches off of whitespace, walk the inheritance chain and include any classes that inherit from Object.

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).

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.
