[PATCH] D90445: [SLP] Make SLPVectorizer to use `llvm.masked.gather` intrinsic

[Alexey Bataev via Phabricator via llvm-commits]

ABataev added inline comments.


================
Comment at: llvm/lib/Transforms/Vectorize/SLPVectorizer.cpp:2848
+        // Vectorizing non-consecutive loads with `llvm.masked.gather`.
+        TreeEntry *TE = newTreeEntry(VL, Bundle /*vectorized*/, S, UserTreeIdx,
+                                     ReuseShuffleIndicies);

Could you give a bit more explanation why it should be treated as `vectorized`?
