[PATCH] D14261: [X86][SSE] Recursive search for zeroable shuffle elements

[Chandler Carruth via llvm-commits]

chandlerc added a comment.

I'm really not convinced this is the correct approach.

Instead, I think we should combine SHUFFLE_VECTOR nodes into a single node so that we don't need this kind of recursive logic. If that doesn't work for some reason, I think that needs to be pretty clearly explained.
