I do want to say that I think the Itanic would have fared way, way better in a post-LLVM world where the importance of smart, optimizing compilers is much more valued and understood and language designers actively work hand-in-hand with compiler devs far more often (with much more significant back-and-forth from hardware manufacturers).
Why would llvm be particularly good at optimizing vliw code when there’s no demand for it to be? You can’t believe everything else would remain the same in the hypothetical I posed.
