and, i should note, the sun4ms are handled differently depending on ross,
cypress, ti, etc. You can check this out on any binary distribution of
sunos/solaris sun4m kernel. hence my question: can netbsd succeed where
sun did not? I am afraid arch/sparc may be a little limiting in the way
the tree is set up. I would feel better with arch/sun4c.
on a different note, hope nobody is using the 'swap' instruction in the
kernel code. have not looked yet. It's a gotcha as it will appear to work
on many V8 implementations.
