Yup. Considered that. Their trapping is not as comprehensive as zSeries,
and I could not justify them.

SPARCs are big-endian and trap on unaligned access (at least that was
the case when I last used one long ago), while S/370 ff. does not trap
on unaligned access.  What's wrong with SPARC?  What other trapping do
you have in mind?
