Richard,
Will gcc 4.3.0's release be held up until all of the major
architectures have fully optimized cost models for vectorization?
I ask because as far as I can tell the powerpc cost model changes
haven't been submitted yet. It certainly would be nice if all
of the major targets could have -fvect-cost-model enabled by
default for -O3.
