[PATCH] D85516: [SVE][CodeGen] Fix issues with EXTRACT_SUBVECTOR when using scalable FP vectors

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

Maybe we should just change the documentation and enforce the rule in SelectionDAG::getNode()?  Maybe simpler.  I guess it has to be a constant anyway?

Doing it in "legalization" would imply operation legalization, not type legalization, since i32 is a legal type.  Probably have to do it in target-specific code, since there isn't any good way to express the rule to LegalizaeDAG.
