	Moves the pointer down.
#define	__MOVE_PTR_UP(type, ptr)   ((ptr) += sizeof(type))
	Moves the pointer up.
#define	PUSH_VALUE_ON_STACK(ptr, value)   (__ACCESS_PTR(__typeof__(value), __MOVE_PTR_DOWN(__typeof__(value), ptr)) = (value))
	First, it moves the pointer down, and then it pushes the value at that memory location.
#define	POP_VALUE_FROM_STACK(value, ptr)   ({value = __ACCESS_PTR(__typeof__(value), ptr); __MOVE_PTR_UP(__typeof__(value), ptr); })
