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.
Do you agree or disagree?
