Also true for ARM CPU emulation. The theoretical aim there as far
as I'm concerned is architectural correctness -- in other words we
should be a valid implementation of the architecture, but where the
architecture says things are UNPREDICTABLE or IMPLEMENTATION DEFINED
we don't necessarily do what any particular real hardware
implementation does. Device accuracy [ie "if modelling an A8,
do what an A8 does"] is not really done at all beyond the really
obvious things like ID registers.
