      RegExp: remove last match info override. · 85e085b7
      yangguo authored 
      With ES6 21.2.5.8, step 13, we no longer have to keep up the illusion
that matching and calling replace function is interleaved. This is
observable through unspec'ed static properties such as RegExp.$1.

Last match info not working yet.

      Move builtin JavaScript sources into own directory. · e5320d8a
      mstarzinger authored 
      This moves JavaScript source files that are bundled with V8 into a
separate directory. The goal is to improve code readability and also
being able to formalize ideal reviewers by subsequently adding the
OWNERS file. These files almost exclusively contain implementations
of methods fully specified by ES6.

Note that files in the "debug" directory as well as the "d8.js" file
aren't affected by this change.

      [es6] Fix missing bits for full @@toPrimitive support. · 2a0759d3
      bmeurer authored 
      Introduce %_ToNumber intrinsic, which just calls to the existing
ToNumberStub, and remove all uses of our custom JavaScript plus
intrinsics based ToNumber and friends.

Also replace the TO_NUMBER_INLINE macro with TO_NUMBER,
which is currently a wrapper for %_ToNumber. Newly written JS
code should use TO_NUMBER (similar to TO_STRING, TO_INT32,
and friends).

Also finally remove the DefaultString/DefaultNumber builtins, which
are basically the ES5 version of ToPrimitive. Now all code uses the
ES6 version, which is implemented in Object::ToPrimitive and
JSReceiver::ToPrimitive in C++.

      [es6] Introduce %ToInteger and %ToLength. · 93b2b262
      bmeurer authored 
      This adds ES6 compliant Object::ToInteger, Object::ToInt32,
Object::ToUint32 and Object::ToLength, and replaces the old
Execution wrappers of those abstract operations (which were
not using the correct ToPrimitive).

This also introduces proper %ToInteger and %ToLength runtime
entries, with a fast path %_ToInteger supported in fullcodegen
and Crankshaft (for now). Internal JavaScript code should use
TO_INTEGER and TO_LENGTH respectively.

      [runtime] Replace %to_string_fun with %_ToString. · 7a7b692b
      bmeurer authored 
      Introduce a new macro TO_STRING that maps to %_ToString and use that
instead of calling into any of the ToString/NonStringToString JavaScript
builtins. Also remove the TO_STRING_INLINE macro, which is basically
obsolete with %_ToString. We still have a few uses of ToString left (via
the utils export mechanism), where we need to investigate whether we
will tank badly if we replace them with TO_STRING as well.

      [builtins] Unify the String constructor. · a3d6f6cc
      bmeurer authored 
      Implement the String constructor completely as native builtin,
avoiding the need to do gymnastics in JavaScript builtin to
properly detect the no argument case (which is different from
the undefined argument case) and also allowing to just
tailcall through to ToString or SymbolDescriptiveString for
the common case. Also the JavaScript builtin was misleading
since the case for construct call was unused, but could be
triggered in a wrong way once we support tail calls from
constructor functions.

This refactoring allows us to properly implement subclassing
for String builtins, once we have the correct initial_map on
derived classes (it's merely a matter of using NewTarget
instead of the target register now).

This introduces a new %SymbolDescriptiveString runtime
entry, which is also used by Symbol.toString() now.

      [es6] Move builtin constructors for primitives to strict mode. · e2f1c269
      bmeurer authored 
      The ES6 specification says that "Built-in functions that are ECMAScript
function objects must be strict mode functions", which in particular
means that you can never test for them using the "caller" field of a
sloppy mode function.

      [es6] Initial steps towards a correct implementation of IsCallable. · 8a378f46
      bmeurer authored 
      This turns the has_instance_call_handler bit on Map into an is_callable
bit, that matches the spec definition of IsCallable (i.e. instances have
[[Call]] internal methods).

Also fix the typeof operator to properly say "function" for everything
that is callable.

Also remove the (unused) premature %_GetPrototype optimization from
Crankshaft, which just complicated the Map bit swap.

      Native context: debug.js does not load from js builtins object anymore. · eb8c0928
      yangguo authored 
      This mainly changes how we share ToBoolean, ToNumber and ToString between
native scripts. Instead of putting them on the js builtins object, we now
explicitly export and import those functions.

I also had to change the import/export mechanism slightly. Previously,
exports and imports are hooked up after all native scripts have been
executed. This means that imported functions cannot be called at the time
the native script is executed.

However, since ToBoolean (and also e.g. ObjectDefineProperties) is called
in v8natives.js, I changed the mechanism so that exports from previous
native scripts (runtime.js for ToBoolean) is imported immediately and can
be called.
