[PATCH] D117499: [CodeGen] Support extracting fixed-length vectors from illegal scalable vectors

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

Any thoughts on lowering to the stack, vs. generating "select" operations?  If I'm not mistaken, at least for SVE, we should always be extract elements from exactly one half of the split.  Not sure how much it matters in practice, though.

Do we need to special-case i1 vectors?
