[PATCH] D96174: [SelectionDAG][AArch64] Restrict matchUnaryPredicate to only handle SPLAT_VECTOR for scalable vectors.

[Craig Topper via Phabricator via llvm-commits]

craig.topper added a comment.

Maybe a different question we should ask is whether we should be allowing SPLAT_VECTOR with fixed vector types. BuildVectorSDNode already has a query for splat. If I recall correctly we've been adding special scalable vector only shuffle nodes that don't work with fixed vectors. Maybe SPLAT_VECTOR should be the same?
