<pre>A "cached" null setter should throw a TypeException when called in strict mode and doesn't
https://bugs.webkit.org/show_bug.cgi?id=139418
Reviewed by Filip Pizlo.
Source/JavaScriptCore:
Made a new NullSetterFunction class similar to NullGetterFunction. The difference is that
NullSetterFunction will throw a TypeError per the ECMA262 spec for a strict mode caller.
* CMakeLists.txt:
* JavaScriptCore.vcxproj/JavaScriptCore.vcxproj:
* JavaScriptCore.vcxproj/JavaScriptCore.vcxproj.filters:
* JavaScriptCore.xcodeproj/project.pbxproj:
Added new files NullSetterFunction.cpp and NullSetterFunction.h.
* runtime/GetterSetter.h:
(JSC::GetterSetter::GetterSetter):
(JSC::GetterSetter::isSetterNull):
(JSC::GetterSetter::setSetter):
Change setter instances from using NullGetterFunction to using NullSetterFunction.
* runtime/JSGlobalObject.cpp:
(JSC::JSGlobalObject::init):
* runtime/JSGlobalObject.h:
(JSC::JSGlobalObject::nullSetterFunction):
Added m_nullSetterFunction and accessor.
* runtime/NullSetterFunction.cpp: Added.
(JSC::GetCallerStrictnessFunctor::GetCallerStrictnessFunctor):
(JSC::GetCallerStrictnessFunctor::operator()):
(JSC::GetCallerStrictnessFunctor::callerIsStrict):
(JSC::callerIsStrict):
Method to determine if the caller is in strict mode.
(JSC::callReturnUndefined):
(JSC::constructReturnUndefined):
(JSC::NullSetterFunction::getCallData):
(JSC::NullSetterFunction::getConstructData):
* runtime/NullSetterFunction.h: Added.
(JSC::NullSetterFunction::create):
(JSC::NullSetterFunction::createStructure):
(JSC::NullSetterFunction::NullSetterFunction):
Class with handlers for a null setter.
LayoutTests:
New regression test.
* js/regress-139418-expected.txt: Added.
* js/regress-139418.html: Added.
* js/script-tests/regress-139418.js: Added.
