A bit over 3% faster on V8 tests.

  • JavascriptCore.exp: Export leak-related functions..
  • API/JSCallbackConstructor.h: (JSC::JSCallbackConstructor::createStructureID): Set HasStandardGetOwnPropertySlot since this class doesn't override getPropertySlot.
  • API/JSCallbackFunction.h: (JSC::JSCallbackFunction::createStructureID): Ditto.
  • VM/ExceptionHelpers.cpp: (JSC::InterruptedExecutionError::InterruptedExecutionError): Use a structure that's created just for this class instead of trying to share a single "null prototype" structure.
  • VM/Machine.cpp: (JSC::Machine::cti_op_create_arguments_no_params): Rename Arguments::ArgumentsNoParameters to Arguments::NoParameters.


  • kjs/Arguments.h: Rename the enum from Arguments::ArgumentsParameters to Arguments::NoParametersType and the value from Arguments::ArgumentsNoParameters to Arguments::NoParameters. (JSC::Arguments::createStructureID): Added. Returns a structure without HasStandardGetOwnPropertySlot since this class overrides getOwnPropertySlot. (JSC::Arguments::Arguments): Added an assertion that there are no parameters.
  • kjs/DatePrototype.h: (JSC::DatePrototype::createStructureID): Added. Returns a structure without HasStandardGetOwnPropertySlot since this class overrides getOwnPropertySlot.
  • kjs/FunctionPrototype.h: (JSC::FunctionPrototype::createStructureID): Set HasStandardGetOwnPropertySlot since this class doesn't override getPropertySlot.
  • kjs/InternalFunction.h: (JSC::InternalFunction::createStructureID): Ditto.
  • kjs/JSArray.h: (JSC::JSArray::createStructureID): Added. Returns a structure without HasStandardGetOwnPropertySlot since this class overrides getOwnPropertySlot.
  • kjs/JSCell.h: Added declaration of fastGetOwnPropertySlot; a non-virtual version that uses the structure bit to decide whether to call the virtual version.
  • kjs/JSFunction.h: (JSC::JSFunction::createStructureID): Added. Returns a structure without HasStandardGetOwnPropertySlot since this class overrides getOwnPropertySlot.
  • kjs/JSGlobalData.cpp: (JSC::JSGlobalData::JSGlobalData): Initialize new structures; removed nullProtoStructureID.
  • kjs/JSGlobalData.h: Added new structures. Removed nullProtoStructureID.
  • kjs/JSGlobalObject.h: (JSC::JSGlobalObject::createStructureID): Added. Returns a structure without HasStandardGetOwnPropertySlot since this class overrides getOwnPropertySlot.
  • kjs/JSNotAnObject.h: (JSC::JSNotAnObjectErrorStub::JSNotAnObjectErrorStub): Use a structure that's created just for this class instead of trying to share a single "null prototype" structure. (JSC::JSNotAnObjectErrorStub::isNotAnObjectErrorStub): Marked this function virtual for clarity and made it private since no one should call it if they already have a pointer to this specific type. (JSC::JSNotAnObject::JSNotAnObject): Use a structure that's created just for this class instead of trying to share a single "null prototype" structure. (JSC::JSNotAnObject::createStructureID): Added. Returns a structure without HasStandardGetOwnPropertySlot since this class overrides getOwnPropertySlot.
  • kjs/JSObject.h: (JSC::JSObject::createStructureID): Added HasStandardGetOwnPropertySlot. (JSC::JSObject::inlineGetOwnPropertySlot): Added. Used so we can share code between getOwnPropertySlot and fastGetOwnPropertySlot. (JSC::JSObject::getOwnPropertySlot): Moved so that functions are above the functions that call them. Moved the guts of this function into inlineGetOwnPropertySlot. (JSC::JSCell::fastGetOwnPropertySlot): Added. Checks the HasStandardGetOwnPropertySlot bit and if it's set, calls inlineGetOwnPropertySlot, otherwise calls getOwnPropertySlot. (JSC::JSObject::getPropertySlot): Changed to call fastGetOwnPropertySlot. (JSC::JSValue::get): Changed to call fastGetOwnPropertySlot.
  • kjs/JSWrapperObject.h: Made constructor protected to emphasize that this class is only a base class and never instantiated.
  • kjs/MathObject.h: (JSC::MathObject::createStructureID): Added. Returns a structure without HasStandardGetOwnPropertySlot since this class overrides getOwnPropertySlot.
  • kjs/NumberConstructor.h: (JSC::NumberConstructor::createStructureID): Ditto.
  • kjs/RegExpConstructor.h: (JSC::RegExpConstructor::createStructureID): Ditto.
  • kjs/RegExpObject.h: (JSC::RegExpObject::createStructureID): Ditto.
  • kjs/StringObject.h: (JSC::StringObject::createStructureID): Ditto.
  • kjs/TypeInfo.h: Added HasStandardGetOwnPropertySlot flag and hasStandardGetOwnPropertySlot accessor function.

JavaScriptGlue:

2008-10-22 Darin Adler <Darin Adler>

Reviewed by Sam Weinig.

  • JSRun.cpp: (JSGlueGlobalObject::JSGlueGlobalObject): Moved constructor here. Set up flags in its new location in global object data, and set up a structure for UserObjectImp too. (JSRun::JSRun): Added code to give the JSGlueGlobalObject its own unique structure, rather than using the default one from JSGlobalObject.
  • JSRun.h: Made JSGlueGlobalObject take a structure ID. Also moved the data into a separate data object. And added userObjectStructure, a Structure to be used by UserObjectImp.
  • JSUtils.cpp: Removed unused sharedGlobalData global. (JSObjectKJSValue): Pass Structure in when creating UserObjectImp. (unprotectGlobalObject): Use JSGlueGLobalObject type specifically. (initializeGlobalObjectKey): Removed code to set up unused sharedGlobalData. (getThreadGlobalObject): Added. Shared by JSObjectKJSValue and getThreadGlobalExecState. Also now passes in a structure ID when creating the global object. (getThreadGlobalExecState): Changed to call getThreadGlobalObject.
  • UserObjectImp.cpp: (UserObjectImp::UserObjectImp): Changed to take a structure.
  • UserObjectImp.h: (UserObjectImp::createStructureID): Added. Returns a structure without HasStandardGetOwnPropertySlot since this class overrides getOwnPropertySlot.

Reviewed by Sam Weinig.

  • bindings/js/JSDOMWindowShell.h: (WebCore::JSDOMWindowShell::createStructureID): Added. Returns a structure without HasStandardGetOwnPropertySlot since this class overrides getOwnPropertySlot.
  • bindings/js/JSInspectorCallbackWrapper.cpp: (WebCore::JSInspectorCallbackWrapper::wrap): Change to use a unique structure for this class rather than sharing nullProtoStructureID, which no longer exists.
  • bindings/js/JSNamedNodesCollection.h: (WebCore::JSNamedNodesCollection::createStructureID): Added. Returns a structure without HasStandardGetOwnPropertySlot since this class overrides getOwnPropertySlot.
  • bindings/js/JSRGBColor.h: (WebCore::JSRGBColor::createStructureID): Ditto.
  • bindings/scripts/CodeGeneratorJS.pm: Added createStructureID functions for the wrappers, constructors, and prototypes in any case where they override getOwnPropertySlot, without HasStandardGetOwnPropertySlot.
  • bridge/objc/objc_runtime.h: (JSC::Bindings::ObjcFallbackObjectImp::createStructureID): Added. Returns a structure without HasStandardGetOwnPropertySlot since this class overrides getOwnPropertySlot.
  • bridge/qt/qt_runtime.h: (JSC::Bindings::QtRuntimeMethod::createStructureID): Ditto.
