[PATCH] D65612: Handle casts changing pointer size in the vectorizer

[Artem Belevich via Phabricator via llvm-commits]

tra added inline comments.


================
Comment at: lib/Transforms/Vectorize/LoadStoreVectorizer.cpp:351-366
+  if (NewPtrBitWidth > PtrBitWidth) {
+    OffsetA = OffsetA.sext(NewPtrBitWidth);
+    OffsetB = OffsetB.sext(NewPtrBitWidth);
+    PtrDelta = PtrDelta.sext(NewPtrBitWidth);
+  } else if (NewPtrBitWidth < PtrBitWidth) {
+    // In case if we have to shrink the pointer
+    // stripAndAccumulateInBoundsConstantOffsets should properly handle a
----------------
This can probably be collapsed to `OffsetA = OffsetA.sextOrTrunk(NewPtrBitWidth);`
same for OffsetB & PtrDelta.
