[PATCH] D152258: [LV] Add mask support for vectorizing interleaved groups

[mgabka via Phabricator via llvm-commits]

mgabka added inline comments.


================
Comment at: llvm/lib/Transforms/Vectorize/LoopVectorize.cpp:2679
+    if (VF.isScalable()) {
+      assert(!MaskForGaps && "Interleaved groups with gaps are not supported.");
+      auto *BlockInMaskPart = State.get(BlockInMask, Part);
----------------
could you add an assert here:
 assert(InterleaveFactor == 2 &&
             "Unsupported deinterleave factor for scalable vectors");

there is one in line 2731m but this function is called before reaching that line.
