[PATCH] D140332: [ADT] Alias llvm::Optional to std::optional

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

Can you push `using OptionalFileEntryRef = CustomizableOptional<FileEntryRef>;` and the renaming as a separate commit to make this patch smaller?
There is a smaller that this rename may be reverted.
205c0589f918f95d2f2c586a01bea2716d73d603 <https://reviews.llvm.org/rG205c0589f918f95d2f2c586a01bea2716d73d603> reverted a change related to `OptionalFileEntryRef`. I assume that your change is fine.



================
Comment at: mlir/include/mlir/IR/Visitors.h:49
   bool operator==(const WalkResult &rhs) const { return result == rhs.result; }
+  bool operator!=(const WalkResult &rhs) const { return result != rhs.result; }

Can be pushed separately
