  • eliminate JSValue::type()

This will make it slightly easier to change the JSImmediate design without
having to touch so many call sites.

SunSpider says this change is a wash (looked like a slight speedup, but not
statistically significant).

  • API/JSStringRef.cpp: Removed include of JSType.h.
  • API/JSValueRef.cpp: Removed include of JSType.h. (JSValueGetType): Replaced use of JSValue::type() with JSValue::is functions.
  • VM/JSPropertyNameIterator.cpp: Removed type() implementation. (KJS::JSPropertyNameIterator::toPrimitive): Changed to take PreferredPrimitiveType argument instead of JSType.
  • VM/JSPropertyNameIterator.h: Ditto.
  • VM/Machine.cpp: (KJS::fastIsNumber): Updated for name change. (KJS::fastToInt32): Ditto. (KJS::fastToUInt32): Ditto. (KJS::jsAddSlowCase): Updated toPrimitive caller for change from JSType to PreferredPrimitiveType. (KJS::jsAdd): Replaced calls to JSValue::type() with calls to JSValue::isString(). (KJS::jsTypeStringForValue): Replaced calls to JSValue::type() with multiple calls to JSValue::is -- we could make this a virtual function instead if we want to have faster performance. (KJS::Machine::privateExecute): Renamed JSImmediate::toTruncatedUInt32 to JSImmediate::getTruncatedUInt32 for consistency with other functions. Changed two calls of JSValue::type() to JSValue::isString().
  • kjs/GetterSetter.cpp: (KJS::GetterSetter::toPrimitive): Changed to take PreferredPrimitiveType argument instead of JSType. (KJS::GetterSetter::isGetterSetter): Added.
  • kjs/GetterSetter.h:
  • kjs/JSCell.cpp: (KJS::JSCell::isString): Added. (KJS::JSCell::isGetterSetter): Added. (KJS::JSCell::isObject): Added.
  • kjs/JSCell.h: Eliminated type function. Added isGetterSetter. Made isString and isObject virtual. Changed toPrimitive to take PreferredPrimitiveType argument instead of JSType. (KJS::JSCell::isNumber): Use Heap::isNumber for faster performance. (KJS::JSValue::isGetterSetter): Added. (KJS::JSValue::toPrimitive): Changed to take PreferredPrimitiveType argument instead of JSType.
  • kjs/JSImmediate.h: Removed JSValue::type() and replaced JSValue::toTruncatedUInt32 with JSValue::getTruncatedUInt32. (KJS::JSImmediate::isEitherImmediate): Added.
  • kjs/JSNotAnObject.cpp: (KJS::JSNotAnObject::toPrimitive): Changed to take PreferredPrimitiveType argument instead of JSType.
  • kjs/JSNotAnObject.h: Ditto.
  • kjs/JSNumberCell.cpp: (KJS::JSNumberCell::toPrimitive): Ditto.
  • kjs/JSNumberCell.h: (KJS::JSNumberCell::toInt32): Renamed from fastToInt32. There's no other "slow" version of this once you have a JSNumberCell, so there's no need for "fast" in the name. It's a feature that this hides the base class toInt32, which does the same job less efficiently (and has an additional ExecState argument). (KJS::JSNumberCell::toUInt32): Ditto.
  • kjs/JSObject.cpp: (KJS::callDefaultValueFunction): Use isGetterSetter instead of type. (KJS::JSObject::getPrimitiveNumber): Use PreferredPrimitiveType. (KJS::JSObject::defaultValue): Ditto. (KJS::JSObject::defineGetter): Use isGetterSetter. (KJS::JSObject::defineSetter): Ditto. (KJS::JSObject::lookupGetter): Ditto. (KJS::JSObject::lookupSetter): Ditto. (KJS::JSObject::toNumber): Use PreferredPrimitiveType. (KJS::JSObject::toString): Ditto. (KJS::JSObject::isObject): Added.
  • kjs/JSObject.h: (KJS::JSObject::inherits): Call the isObject from JSCell; it's now hidden by our override of isObject. (KJS::JSObject::getOwnPropertySlotForWrite): Use isGetterSetter instead of type. (KJS::JSObject::getOwnPropertySlot): Ditto. (KJS::JSObject::toPrimitive): Use PreferredPrimitiveType.
  • kjs/JSString.cpp: (KJS::JSString::toPrimitive): Use PreferredPrimitiveType. (KJS::JSString::isString): Added.
  • kjs/JSString.h: Ditto.
  • kjs/JSValue.h: Removed type(), added isGetterSetter(). Added PreferredPrimitiveType enum and used it as the argument for the toPrimitive function. (KJS::JSValue::getBoolean): Simplified a bit an removed a branch.
  • kjs/collector.cpp: (KJS::typeName): Changed to use JSCell::is functions instead of calling JSCell::type.
  • kjs/collector.h: (KJS::Heap::isNumber): Renamed from fastIsNumber.
  • kjs/nodes.h: Added now-needed include of JSType, since the type is used here to record types of values in the tree.
  • kjs/operations.cpp: (KJS::equal): Rewrote to no longer depend on type(). (KJS::strictEqual): Ditto.

  • eliminate JSValue::type()
  • bridge/c/c_instance.cpp: (KJS::Bindings::CInstance::defaultValue): Take PreferredPrimitiveType argument instead of JSType argument. Removed unneeded code to handle boolean, since that's never passed.
  • bridge/c/c_instance.h: Ditto.
  • bridge/c/c_utility.cpp: (KJS::Bindings::convertValueToNPVariant): Use JSValue::is functions instead of JSValue::type(). Removed unneeded code to handle "unspecified".
  • bridge/jni/jni_instance.cpp: (JavaInstance::defaultValue): Take PreferredPrimitiveType argument instead of JSType argument. Removed unneeded code to handle boolean.
  • bridge/jni/jni_instance.h: Ditto.
  • bridge/jni/jni_jsobject.mm: (JavaJSObject::convertValueToJObject): Use JSValue::is functions instead of JSValue::type().
  • bridge/objc/objc_instance.h: Take PreferredPrimitiveType argument instead of JSType argument. Removed unused argument.
  • bridge/objc/objc_instance.mm: (ObjcInstance::getValueOfUndefinedField): Removed unused argument. (ObjcInstance::defaultValue): Take PreferredPrimitiveType argument instead of JSType argument. Removed unneeded code to handle boolean and another dead code path for unknown types.
  • bridge/objc/objc_runtime.h: Take PreferredPrimitiveType argument instead of JSType argument. Removed override of type() that caused the fallback object to return "UndefinedType" when there is no invokeUndefinedMethodFromWebScript:withArguments: method defined. That didn't accomplish much, since most checks for undefined don't ever call type().
  • bridge/objc/objc_runtime.mm: (ObjcFallbackObjectImp::defaultValue): Ditto.
  • bridge/qt/qt_instance.cpp: (KJS::Bindings::QtInstance::defaultValue): Take PreferredPrimitiveType argument instead of JSType argument. Removed unneeded code to handle boolean.
  • bridge/qt/qt_instance.h: Ditto.
  • bridge/runtime.h: (KJS::Bindings::Instance::getValueOfUndefinedField): Removed unsed argument.
  • bridge/runtime_object.cpp: (RuntimeObjectImp::defaultValue): Take PreferredPrimitiveType argument instead of JSType argument.
  • bridge/runtime_object.h: Ditto.
