示例1:

/// isVariadicMessage - Returns whether the given message is a variadic message,
/// where all arguments must be Objective-C types.
bool
VariadicMethodTypeChecker::isVariadicMessage(const ObjCMessage &msg) const {
    const ObjCMethodDecl *MD = msg.getMethodDecl();

    if (!MD || !MD->isVariadic() || isa<ObjCProtocolDecl>(MD->getDeclContext()))
        return false;

    Selector S = msg.getSelector();

    if (msg.isInstanceMessage()) {
        // FIXME: Ideally we'd look at the receiver interface here, but that's not
        // useful for init, because alloc returns 'id'. In theory, this could lead
        // to false positives, for example if there existed a class that had an
        // initWithObjects: implementation that does accept non-Objective-C pointer
        // types, but the chance of that happening is pretty small compared to the
        // gains that this analysis gives.
        const ObjCInterfaceDecl *Class = MD->getClassInterface();

        // -[NSArray initWithObjects:]
        if (isReceiverClassOrSuperclass(Class, "NSArray") &&
                S == initWithObjectsS)
            return true;

        // -[NSDictionary initWithObjectsAndKeys:]
        if (isReceiverClassOrSuperclass(Class, "NSDictionary") &&
                S == initWithObjectsAndKeysS)
            return true;

        // -[NSSet initWithObjects:]
        if (isReceiverClassOrSuperclass(Class, "NSSet") &&
