- Careful! This works for r1mach, and in general if the constants are
- given in human-readable form, but I have seen d1mach in which the
- constants were given as two 32-bit hexadecimal numbers. In that case,
- you have to worry about byte ordering, i.e. you may have to reverse
- the two hex numbers between one machine and another.
