Richard,
Just to clarify, does this mean that any architecture
which doesn't have a fully optimized cost-model currently
in gcc trunk will have to wait for gcc 4.4? I ask because
the cost-model bugs wouldn't actually be a regressions
from gcc 4.2. I mainly wanted to make sure that we didn't
have some cost-model changes sitting around unsubmitted
that would have to be postponed until gcc 4.4.
