[PATCH] D122875: [DAGCombiner] Scalarize extend/truncate for splat vector.

[Fraser Cormack via Phabricator via llvm-commits]

frasercrmck added a comment.

Sorry, I'm a bit rusty. What happens with the equivalent fixed-length vector splats (BUILD_VECTOR)? If they're scalarized can we do the same for SPLAT_VECTOR in the same place? If they're not scalarized, what's the logic for only doing this transform for SPLAT_VECTOR?
