      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.

      TimeClip converts -0 to +0, following ES2015 spec · eeaf80cd
      littledan authored 
      In ES2015, section 20.3.1.15, TimeClip (an internal algorihtm which is
called when normalizing Date representations) is specified to add 0
to its result, which converts -0 into +0. This patch adds that conversion
to the Date code. It is verified by the test262 test
built-ins/Date/TimeClip_negative_zero

      [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++.

      [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.

      [es6] Implement spec compliant ToPrimitive in the runtime. · f6c6d713
      bmeurer authored 
      This is the first step towards a spec compliant ToPrimitive
implementation (and therefore spec compliant ToNumber, ToString,
ToName, and friends).  It adds support for the @@toPrimitive
symbol that was introduced with ES2015, and also adds the new
Symbol.prototype[@@toPrimitive] and Date.prototype[@@toPrimitive]
initial properties.

There are now runtime functions for %ToPrimitive, %ToNumber and
%ToString, which do the right thing and should be used as fallbacks
instead of the hairy runtime.js implementations.  I will do the
same for the other conversion operations mentioned by the spec in
follow up CLs.  Once everything is in place we can look into
optimizing things further, so that we don't always call into the
runtime.

Also fixed Date.prototype.toJSON to be spec compliant.

      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.

      [stubs] Unify (and optimize) implementation of ToObject. · 4fc6f547
      bmeurer authored 
      This is the initial (big) step towards a more uniform implementation of
the ToObject abstract operation (ES6 7.1.13), where we have a fallback
implementation in JSReceiver::ToObject() and a fast (hydrogen) CodeStub
to deal with the fast case (we should be able to do more cleanup on this
in a followup CL).  For natives we expose the abstract operation via a
%_ToObject intrinsic, also exposed via a macro TO_OBJECT, that unifies
the previous confusion with TO_OBJECT_INLINE, ToObject, TO_OBJECT,
$toObject and %$toObject.  Now the whole implementation of the abstract
operation is context independent, meaning we don't need any magic in the
builtins object nor the native context.

      [date] Refactor the %_DateField intrinsic to be optimizable. · e4782a9b
      bmeurer authored 
      Previously the %_DateField intrinsic would also check the object and
throw an exception if you happen to pass something that is not a valid
JSDate, which (a) violates our policy for instrinsics and (b) is hard to
optimize in TurboFan (even Crankshaft has a hard time, but there we will
never inline the relevant builtins, so it doesn't show up). The throwing
part is now a separate intrinsics %_ThrowIfNotADate that throws an
exception in full codegen and deoptimizes in Crankshaft, which means the
code for the current use cases is roughly the same (modulo some register
renamings/gap moves).
