## 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 significantly extends the FuseReductionEpilogue pass by introducing robust support for clipping patterns. This enhancement allows the compiler to fuse min(max(value, lower), upper) operations directly into reduction blocks, improving performance by reducing memory traffic and enabling more aggressive optimizations. The changes involve updating the epilogue pattern analysis, modifying the initialization and per-iteration application of fused operations, and adding comprehensive test coverage to ensure correctness across various clipping expressions and dataflow scenarios. ### Highlights * **Clipping Pattern Support**: Introduced EpilogueType::Clipping to categorize clipping operations within the FuseReductionEpilogue mechanism. * **Enhanced Pattern Analysis**: Enhanced AnalyzeEpiloguePattern to recognize common clipping patterns, specifically min(max(temp, lower), upper) and its commutative variants. * **Clipping Bounds Storage**: Added clipping_lower_ and clipping_upper_ members to ReductionEpilogueFuser to store the bounds for clipping. * **Initial Value Clipping**: Modified CreateFusedReductionBlock to correctly apply clipping to the initial value of the reduction, ensuring semantic preservation. * **Per-Iteration Clipping**: Updated the BufferReplacer to apply clipping operations per-iteration during the fusion process. * **Comprehensive Testing**: Included new Python tests to thoroughly validate the clipping pattern fusion, covering trace roundtrip, numerical correctness, and complex dataflows with multiple epilogues. <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>`.
