Thanks for doing this Alex. The test coverage is great. Thanks!



================
Comment at: mlir/lib/Dialect/StandardOps/IR/Ops.cpp:1509
 
-  if (getNumOperands() != getTagMemRefRank() + getSrcMemRefRank() +
-                              getDstMemRefRank() + 3 + 1 &&
-      getNumOperands() != getTagMemRefRank() + getSrcMemRefRank() +
-                              getDstMemRefRank() + 3 + 1 + 2) {
+  // Stride-related operands are optional.
+  if (numOperands != numExpectedOperands &&
----------------
Maybe comment that both optional operands need to be present (or none). You have that reflected in the code, but a comment would help explain the + 2.
