I thought that was what I said, maybe I wasn't very clear. Anyway, it's a really interesting range of problems, as is what's worked and what hasn't. Personally

I thought that was what I said, maybe I wasn't very clear. Anyway, it's a really interesting range of problems, as is what's worked and what hasn't. Personally I think code morphing still has a lot of promise, but mostly in software level "emulation"/trans-coding. Something interesting about Itanium is that eventually it's actually become pretty good. But it's now in a market niche that it's not going to be able to break out of. The big problem with IA64, in my opinion, was that they neglected IA32 performance with the first gen. They made the classic error of prematurely committing to a new design before it was proven, which contrasts greatly to the AMD64 example where they did everything possible to ease the transition and maintain, or even improve, performance with x86 only code.
