+          CommonAlignment =
+              commonAlignment(CommonAlignment, cast<LoadInst>(V)->getAlign());
+        if (TTI->isLegalMaskedGather(FixedVectorType::get(ScalarTy, VL.size()),
----------------
Maybe it's worth to use `CommonAlignment` for `getEntryCost()` as well? This patch looks good one to take this code from D57059.
