   David, I see that this is based on your renumbering of the
   sparc64 registers (submitted separately).  I don't think
   that renumbering is allowable.  Even if we disregarded
   embedded sparc64 targets, wouldn't this break Solaris?

Solaris would not break, no.

It is a shame that embedded will prevent a renumbering, since
the numbers were choosen a little bit poorly, but what can
we do :(
