> If the destructor is not inline, and also is not provided in that same It is used in an embedded application, and because the mentioned destructor is compiled into one machine-code instruction, it would be a big wastage not to inline it. The class mentioned in my example and the variable are refer to hardware registers, which are in connection by hardware, and (of course) the accessing order is important. Is there any possibility to tell the compiler such a dependency? Regards K. Gy.
