I'll look again.
But I do recall that the spec is consistent in placing a 3-bit field (values
1-3)
shifted one bit left into the larger 32-bit field, so that in essence the value
is always the real instruction length.
However, qemu was not consistent in performing that multiplication. So there
will be some place that gets changed because of this. Frankly I think it would
be least confusing to always manipulate the full instruction length and never
explicitly perform the multiply.
