[PATCH] D93229: [VectorCombine] allow peeking through GEPs when creating a vector load

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added inline comments.


================
Comment at: llvm/lib/Transforms/Vectorize/VectorCombine.cpp:197
   SmallVector<int, 16> Mask(OutputNumElts, UndefMaskElem);
-  Mask[0] = 0;
+  Mask[0] = OffsetInBits / ScalarSize;
   VecLd = Builder.CreateShuffleVector(VecLd, Mask);
----------------

And also assert that `Mask[0] < MinVecNumElts`.
