[PATCH] D145163: Add support for vectorization of interleaved memory accesses for scalable VF

[Luke Lau via Phabricator via llvm-commits]

luke added inline comments.


================
Comment at: llvm/lib/Transforms/Vectorize/LoopVectorize.cpp:2751
+          StridedVec = Builder.CreateShuffleVector(NewLoads[Part], StrideMask,
+                                                   "strided.vec");
 
----------------
It's somehow possible to reach here with a scalable vector type if `TII->hasInterleavedLoad` returns false. 
Can we check somewhere inside the vectorizer cost model that if `hasInterleavedLoad` is false then we rule out any recipe with an interleave group for a scalable VF?
