We also still have to agree on the target triples for the new port.
If you have any thoughts on this, I'd love to hear them.

It seems fairly obvious that the powerpc-*-eabispe* and
powerpc*-*-linux*spe* triples should continue to work while being mapped
to the new CPU port.  It's less obvious what triples should be used for
SPE versions of other SPE-supporting configurations such as
powerpc-*-eabisim*, powerpc-*-rtems*, powerpc-wrs-vxworks*.

powerpc-*-rtemsspe* would be OK.

powerpc-*-eabisimspe* is pretty ugly though.

It is obvious but if powerpc-*-XXXspe* is the pattern, then the
spe cases need to be above in all configure switches. I hate to
mention it but a fair number of odd RTEMS issues turn out to be
from inadvertent side-effects when cleaning up configure switches.
Some testcases will be applicable to both ports, some to only one.

Maintainers of each port should of course watch the other port for changes
that should be carried across, even if we believe, as has been stated in
this discussion, that the parts of the code that would be present in both
ports are stable and very rarely change.
