Could you be more elaborate on who exactly is paying you for M3 work? ;-)
I'd like to share this experience...

Not personally, but I'd just like to remind you of the fact that
the Sun compilers were/are highly optimized for the SPARC architecture,
so that in certain performance critical domains nobody would use
gcc. I don't really know if this is still a current problem of gcc,
nor do I know if it has much impacts on CM3 as the gcc backend is
used anyway for all M3 code.

It would be interesting how good or bad M3s compiled code actually
is wrt. the different target platforms... I've got no intention to
set up benchmark testing for this though ;-)

Are there any important differences in the linkers? I wouldn't care
much otherwise.
