Seriously though, I think we've reached the point of diminishing gains. We now know how everyone feels. It appears that this is "most people are in favor, some people are against", but everyone seems to have some specific criteria they want met before merging. I'd also like to point out that tree-ssa is, by various benchmarks pointed out earlier, in the worst case, slightly slower than the mainline in compile time, even though it adds *30* optimization passes. That's right. Thirty. Check tree-optimize if you don't believe me. That's quite an accomplishment in and of itself if you ask me. Anyway, It would be more productive if we were to try to concentrate on a specific set of merge criteria for tree-ssa, than continue to discuss the benefits or disadvantages of it (since it seems clear the overwhelming number of people think it has great benefit already) You friendly neighborhood cat herder, Dan
