// Important note about this file: Since everything in here is supposed to be called
// from JIT-compiled VM code it needs to be very careful about calling conventions.
// As a result none of the integer sized struct types may be used as function
// arguments, because current C++ calling conventions require them to be passed
// by reference. The JIT code, however will pass them by value so any direct native function
// taking such an argument needs to receive it as a naked int.
