[JSC] ES6 Method functions should not have prototype

Fix test262 expectations about MethodDefinitions

  • ChakraCore/test/strict/05.arguments_sm.baseline-jsc:
  • stress/reflect-set.js:
  • test262.yaml:

Source/JavaScriptCore:

ECMA-262 only adds "prototype" properties to specific syntactic function forms.
Specific items which do not contain "prototype" include (most) built-in functions (such as Math.pow),
MethodDefinitions which are not either class "constructor" methods or GeneratorMethods, AsyncFunctions,
and ArrowFunctions.

For details, see the following spec text, and the difference between GeneratorMethod evaluation and
the evaluation of other MethodDefinition forms.

  • runtime/Executable.h:
  • runtime/JSFunction.cpp:

(JSC::JSFunction::callerGetter):
(JSC::JSFunction::getOwnPropertySlot):
(JSC::JSFunction::deleteProperty):

  • bytecompiler/BytecodeGenerator.h:

(JSC::BytecodeGenerator::makeFunction):

  • runtime/Executable.h:
  • runtime/JSFunction.cpp:

(JSC::JSFunction::getOwnPropertySlot):
(JSC::JSFunction::getOwnNonIndexPropertyNames):
(JSC::JSFunction::put):
(JSC::JSFunction::deleteProperty):
(JSC::JSFunction::defineOwnProperty):

  • runtime/JSGlobalObjectFunctions.cpp:

(JSC::globalFuncThrowTypeErrorArgumentsCalleeAndCaller):

LayoutTests:

Update expected error message to no longer indicate "strict mode"
(which is not always true), and add additional tests for the presence
of "caller" and "arguments" on accessor MethodDefinitions.

     3        [JSC] ES6 Method functions should not have prototype
     4        https://bugs.webkit.org/show_bug.cgi?id=162530
     5
     6        Reviewed by Saam Barati.

     8        ECMA-262 only adds "prototype" properties to specific syntactic function forms.
     9        Specific items which do not contain "prototype" include (most) built-in functions (such as Math.pow),
     10        MethodDefinitions which are not either class "constructor" methods or GeneratorMethods, AsyncFunctions,
     11        and ArrowFunctions.
     12       
     13        For details, see the following spec text, and the difference between GeneratorMethod evaluation and
     14        the evaluation of other MethodDefinition forms.
