Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/72730
This diff contains changes from several PRs landed to lazy_tensor_staging branch.
- generating 'fallback' overrides for each codegenned op, useful for debugging
- supports operators which are missing aten:: symbols for op names, instead using their string counterpart
- makes the IR class a base class instead of hardcoding the assumption of TS
Test Plan: tested on lazy_tensor_staging branch
