// In debug builds, Register is defined as a non-integer type to avoid
// possible mix-ups with RegisterMask and integer offsets. In non-debug
// builds, it's defined as an integer just in case some compilers fail to
// optimize single-element structs in the obvious way.
//
// Note that in either case, a Register can be initialized like so:
//
// Register r = { 0 };
//
// In the debug case it's a struct initializer, in the non-debug case it's
// a scalar initializer.
//
// XXX: The exception to all the above is that if NJ_USE_UINT32_REGISTER
// is defined, the back-end is responsible for defining its own Register
// type, which will probably be an enum. This is just to give all the
// back-ends a chance to transition smoothly.
