Actually, looking at it again, there's a python assertion failure before that:
```

That check was introduced in this PR https://github.com/llvm/llvm-project/pull/158455 along with the necessary mlir-tblgen code to make it pass. I'm not how you could have the assert but not the correct generated code - possibly you need to need do a clean build.
