Re: PING^(n+1) fwprop merge (ping 6 or 7 by now)

No slight hit on PPC. I appreciate you reply to my ping, but it would have been helpful if you've read Paolo's complete story. The PPC regression was fixed already even before these fwprop patches were posted.

Correct me if I'm wrong, but the only actual numbers for the final patch I recall seeing were for ix86. I asked for more (after all we're deleting optimization code here and should make sure there aren't any serious regressions), but I don't think anything was ever posted. Providing numbers would be more useful than pinging the extra n times.
