      [regexp] Add 'l' flag to force experimental engine · 5720d205
      Martin Bidlingmaier authored 
      This commit adds the 'l' (linear) RegExp flag (as in e.g. /asdf|123/l)
that forces execution in linear time.  These regexps are handled by the
experimental engine.  If the experimental engine cannot handle the
pattern, an exception is thrown on creation of the regexp.

The commit also adds a new global V8 flag and changes an existing one:
* --enable-experimental-engine, which turns on recognition of the RegExp
  'l' flag.  Previously this flag also caused all supported regexps to
  be executed by the experimental engine; this is not the case anymore.
* --default-to-experimental-regexp-engine takes over the previous
  semantics of --enable-experimental-regexp-engine:  We execute all
  supported regexps with the experimental engine.

      [class] maintain private brand information on SFI · 0753cbea
      Joyee Cheung authored 
      When an empty class is nested inside a class with private instance
methods, like this:

  class Outer {
    constructor() {}
    #method() {}
    factory() {
      class Inner {
        constructor() {  }
      }
      return Inner;
    }
    run(obj) {
      obj.#method();
    }
  }

The bytecode generator previously generate private brand
initialization for the constructor of Inner by mistake,
because during scope chain serialization/deserialization,
the outer scopes of Inner and factory() are not allocated
or serialized (as they are empty). In the eyes of the bytecode
generator, it then appeared as if Outer is the direct outer
scope of Inner's constructor.

In order to work around this information loss, in this patch
we rely on SharedFunctionInfo instead of the Context/ScopeInfo
chain to maintain the information about private brand initialization.
This is done by shrinking expected_nof_properties to 8 bits and
freeing 8 bits for a second bitfield on the SFI.

      [callprinter] Correctly point to the incorrect spread arg · 1d0693e2
      Sathya Gunasekaran authored 
      The source position is set to the function call (console.log) not the
spread (..x), in the bytecode generator, as the spread operation is
done as part of the CallWithSpread bytecode.

The CallPrinter stops at the function call and doesn't look at the
arguments as well (in CallPrinter::VisitCall) to see if the error is
from an incorrect spread operation.


With this patch, we pass some state to the CallPrinter in the
CallWithSpread error case and check that in CallPrinter::VisitCall
before returning.

For the given source string:
```
x = undefined;
console.log(1, ...x);
```

Previously, the error was -

```
test.js:2: TypeError: console.log is not iterable (cannot read property Symbol(Symbol.iterator))
console.log(1, ...x);
        ^
TypeError: console.log is not iterable (cannot read property Symbol(Symbol.iterator))
    at test.js:2:9
```


Now, the error is -

```
_test.js:2: TypeError: x is not iterable (cannot read property undefined)
console.log(1, ...x);
                  ^
TypeError: x is not iterable (cannot read property undefined)
    at _test.js:2:9
```

      [offthread] Add an OffThreadIsolate · 7a20b6b9
      Leszek Swirski authored 
      The Factory/OffThreadFactory allows us to cleanly separate object
construction behaviour between main-thread and off-thread in a
syntactically consistent way (so that methods templated on the factory
type can be made to work on both).

However, there are cases where we also have to access the Isolate, for
handle creation or exception throwing. So far we have been pushing more
and more "customization points" into the factories to allow these
factory-templated methods to dispatch on this isolate behaviour via
these factory methods. Unfortunately, this is an increasing layering
violation between Factory and Isolate, particularly around exception
handling.

Now, we introduce an OffThreadIsolate, analogous to Isolate in the same
way as OffThreadFactory is analogous to Factory. All methods which were
templated on Factory are now templated on Isolate, and methods which
used to take an Isolate, and which were recently changed to take a
templated Factory, are changed/reverted to take a templated Isolate.
OffThreadFactory gets an isolate() method to match Factory's.

Notably, FactoryHandle is changed to "HandleFor", where the template
argument can be either of the Isolate type or the Factory type (allowing
us to dispatch on both depending on what is available).

      [offthread] Add OffThreadFactory support to AST strings · bcbb553d
      Leszek Swirski authored 
      Add support for internalizing an AstValueFactory using the off-thread
factory. Includes adding ConsString support to OffThreadFactory.

This introduces a Handle union wrapper, which is used in locations that
can store a Handle or an OffThreadHandle. This is used in this patch for
the internalized "string" field of AST strings, and will be able to be
used for other similar fields in other classes (e.g. the ScopeInfo
handle in Scope, object boilerplate descriptor handles, the inferred
name handle on FunctionLiterals, etc.). It has a Factory-templated
getter which returns the appropriate handle for the factory, and a
debug-only tag to make sure the right getter is used at runtime. This
union wrapper currently decomposes implicitly to a Handle if the getter
is not called, to minimise code changes, but this implicit conversion
will likely be removed for clarity.

      Store JSMessageObject on rejected promises · b15c02d0
      Simon Zünd authored 
      When V8 throws an uncaught exception, we store a JSMessageObject
with a stack trace and source positions on the isolate itself.
The JSMessageObject can be retrieved by a TryCatch scope
and is used by the inspector to provide additional information to the DevTools
frontend (besides the exception).

Introducing top-level await for REPL mode causes all thrown exceptions
to be turned into a rejected promise. The implicit catch block that does this
conversion clears the JSMessageObject from the isolate as to not leak memory.

This CL preserves the JSMessageObject when the debugger is active and stores
the JSMessageObject on the rejected promise itself. The inspector is changed
to retrieve the JSMessageObject in the existing catch handler and pass the
information along to the frontend.

Drive-by: This CL removes a inspector test that made assumptions when a promise
is cleaned up by the GC. These assumptions no longer hold since we hold on to
the promise longer.

      Introduce REPL mode · fbcc2e87
      Simon Zünd authored 
      Design doc: bit.ly/v8-repl-mode

This CL adds a new REPL mode that can be used via
DebugEvaluate::GlobalREPL. REPL mode only implements re-declaration
of 'let' bindings at the moment. Example:

REPL Input 1: let x = 21;
REPL Input 2: let x = 42;

This would normally throw a SyntaxError, but works in REPL mode.

The implementation is done by:
  - Setting a 'repl mode' bit on {Script}, {ScopeInfo}, {ParseInfo}
    and script {Scope}.
  - Each global let declaration still gets a slot reserved in the
    respective {ScriptContext}.
  - When a new REPL mode {ScriptContext} is created, name clashes
    for let bindings are not reported as errors.
  - Declarations, loads and stores for global let in REPL mode are
    now "load/store global" instead of accessing their respective
    context slot directly. This causes a lookup in the ScriptContextTable
    where the found slot for each name is guaranteed to be the same
    (the first one).

      [class] fix undefined private name access in computed property keys · 7fa12e2a
      Joyee Cheung authored 
      This patch implements https://github.com/tc39/proposal-class-fields/pull/269
and makes sure we always throw TypeError when there is invalid private
name access in computed property keys.

Before this patch, private name variables of private fields and methods
are initialized together with computed property keys in the order they
are declared. Accessing undefined private names in the computed property
keys thus fail silently.

After this patch, we initialize the private name variables of private
fields before we initialize the computed property keys, so that invalid
access to private fields in the computed keys can be checked in the IC.
We now also initialize the brand early, so that invalid access to private
methods or accessors in the computed keys throw TypeError during brand
checks - and since these accesses are guarded by brand checks, we can
create the private methods and accessors after the class is
defined, and merge the home object setting with the creation
of the closures.

      [class] parse private accessors · a6dd7f1c
      Joyee Cheung authored 
      This patch adds:

- VariableMode::kPrivateMethod
- VariableMode::kPrivateSetterOnly
- VariableMode::kPrivateGetterOnly
- VariableMode::kPrivateGetterAndSetter

And replace the previous RequiresBrandCheckFlag by inferring
whether the brand check is required from these VariableModes.
It is then possible to check duplicate non-complementary
accessors in the parsers and throw early errors, and allow
complementary accessors to be associated with the same
private name variable.

This patch also adds the following AssignType:

- PRIVATE_METHOD
- PRIVATE_GETTER_ONLY
- PRIVATE_SETTER_ONLY
- PRIVATE_GETTER_AND_SETTER

corresponding to the new VariableModes so that it's possible
to generate specialized code for different type of
private accessor declarations.

Original change's description:
> [class] implement private method declarations
>
> This patch implements the declarations of private methods, the access
> of private methods would be left to a future patch.
> When a private methods declaration is encountered, we now:
>
> - Create a brand symbol during class evaluation and store it in the
>   context.
> - Create the closures for the private methods
> - Load the brand from the context and store it in the instance in the
>   constructor.

      [cleanup] Use Vector::begin instead of Vector::start · 4b0f9c85
      Clemens Hammacher authored 
      Our {Vector} template provides both {start} and {begin} methods. They
return exactly the same value. Since the {begin} method is needed for
iteration, and is also what standard containers provide, this CL
switches all uses of the {start} method to use {begin} instead.

Patchset 1 was auto-generated by using this clang AST matcher:
    callExpr(
        callee(
          cxxMethodDecl(
            hasName("start"),
            ofClass(hasName("v8::internal::Vector")))
        ),
        argumentCountIs(0))

Patchset 2 was created by running clang-format. Patchset 3 then
removes the now unused {Vector::start} method.
