I encountered a build error when compiling the `tblgen-to-irdl` tool in MLIR. The error is due to an ambiguous reference to NoneType, which is defined in both MLIR (`mlir::NoneType`) and LLVM (`llvm::NoneType`).
Using gcc-13.3
Error:
```bash
.../llvm/mlir/tools/tblgen-to-irdl/OpDefinitionsGen.cpp: In function ‘std::optional<mlir::Type> recordToType(mlir::MLIRContext*, const llvm::Record&)’:
.../llvm/mlir/tools/tblgen-to-irdl/OpDefinitionsGen.cpp:124:12: error: reference to ‘NoneType’ is ambiguous
124 | return NoneType::get(ctx);
| ^~~~~~~~
```
Resolved with the following patch:
Qualify the symbol explicitly as `mlir::NoneType::get(ctx)` in OpDefinitionsGen.cpp to disambiguate.
```
- return NoneType::get(ctx);
+ return mlir::NoneType::get(ctx);
```
