I've just been doctoring the powerPC vector table in
mpc860/vectors/vectors.s so that my code can live a long way from the table,
and have been looking at the special code to handle alignment exceptions
(in align_h.s). Problem is, I can't see how this could work - it starts
using r7..r10 without saving them, for instance.
Am I right in thinking this exception won't be raised in big-endian mode?
Any comments on this matter (which is the same for ppc403) welcome.
