## Summary of Changes Hello @kimm240, I'm Gemini Code Assist[^1]! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request enhances the `FuseReductionEpilogue` pass in the TIR schedule to support clipping operations. By recognizing and fusing `min(max(value, lower), upper)` patterns directly into reduction blocks, this change aims to improve optimization opportunities and reduce intermediate buffer usage. The implementation involves extending the epilogue pattern analysis, updating the reduction block creation logic to handle clipping for both initial values and per-iteration updates, and adding robust test coverage to ensure functional and numerical correctness. ### Highlights * **Epilogue Type Extension**: Added `EpilogueType::Clipping` to the enum to explicitly distinguish clipping patterns. * **Clipping Pattern Detection**: Extended `AnalyzeEpiloguePattern` to correctly detect both `min(max(temp, lower), upper)` and `max(min(temp, upper), lower)` clipping patterns. * **Clipping Bounds Storage**: Introduced `clipping_lower_` and `clipping_upper_` members to the `ReductionEpilogueFuser` class to store the detected clipping bounds. * **Initial Value Clipping**: Modified `CreateFusedReductionBlock` to apply the clipping operation to the initial value of the reduction, ensuring correct semantics from the start. * **Per-Iteration Clipping**: Updated the `BufferReplacer` within `CreateFusedReductionBlock` to apply the clipping operation per-iteration to the stored value, maintaining the desired behavior throughout the reduction. * **Comprehensive Testing**: Added new Python test cases to verify the correct fusion of clipping patterns, numerical correctness against a NumPy reference, and proper behavior in scenarios with multiple epilogue blocks. <details> <summary><b>Using Gemini Code Assist</b></summary> <br> The full guide for Gemini Code Assist can be found on our [documentation page](https://developers.google.com/gemini-code-assist/docs/review-github-code), here are some quick tips. <b>Invoking Gemini</b> You can request assistance from Gemini at any point by creating a comment using either `/gemini <command>` or `@gemini-code-assist <command>`.
