"The Itanium is a noteworthy example of what happens when one designs an architecture exclusively for parallelism to the exclusion of all else, and leaves all instruction scheduling to the compiler. "

Well no, it would be more accurate to say "a noteworthy example of when you release a chip that isn't in line with what common programming languages can do".

That is, there is nothing wrong with doing the above. There's something wrong with doing the above when you most people are writing sequential C++ :)

There simply wasn't enough ILP to extract :)

IE no amount of compiler advance would have saved it.
