Two semi-tangential ideas: I wish it was possible to do things along the lines of "fetch this data from RAM and at the same time start recomputing it, whichever is faster". And also, I wish there was a "branch upcoming &#x2F; branch execute" split. In other words, instead of just "here's a branch", it's more along the lines of "you will have to branch on <x>. <other instructions> now branch on <x>." Effectively a variable number of branch-delay slot(s). Wouldn't help for straight pointer-chasing, but in other situations it could.
