Thanks very much for doing this. The good news is that your code compiles and runs. I don't think we're in a position to do much at this point. The numbers look only slightly different from GCC 3.0.x. There are even some improvements assuming that smaller numbers in your benchmark table imply better results. I agree that we should investigate these issues, but I don't think we should hold up the release to try to work on them.
