[PATCH] D102687: [RISCV] Ensure shuffle splat operands are type-legal

[Craig Topper via Phabricator via llvm-commits]

craig.topper added a comment.

I think the issue for X86 might be that NewNodesMustHaveLegalTypes is set after type legalization, but vector legalization is allowed to create illegal scalar types. A second type legalization runs after. Maybe we should add a bool parameter to the function that defaults to false, but can be set to true to request a legal type?
