Some combination of strategies. Grabbing an old Itanium Developer's manual, the suggested rewrites include making loops branchless where possible, balancing instruction depth for branches that can't be avoided, doing more comparisons in parallel rather than if X -> then if Y, and so on. Obviously, this doesn't apply to every general purpose problem. Just noting there were some narrow cases where writing for Itanium produced something close to the promise.
