[PATCH] D138934: mlir/tblgen: use std::optional in generation

[Jacques Pienaar via Phabricator via llvm-commits]

jpienaar added inline comments.


================
Comment at: mlir/lib/Dialect/Shape/IR/Shape.cpp:1337
     return nullptr;
-  Optional<int64_t> dim = getConstantDim();
+  auto dim = getConstantDim();
   if (!dim.has_value())
----------------
Why couldn't this be std::optional<int64_t> ?
