## 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 introduces a significant optimization to the TVM Tensor IR (TIR) schedule by adding a new primitive, `FuseReductionEpilogue`. This primitive addresses the current limitation of fusing epilogue operations, such as bias addition, directly into reduction blocks. By transforming the IR to integrate the epilogue into the reduction block's initialization, it eliminates intermediate buffer usage and unlocks opportunities for more efficient hardware utilization, particularly for architectures supporting bias accumulation instructions. ### Highlights * **New Primitive**: Introduced `FuseReductionEpilogue` to the TVM TIR schedule, allowing the fusion of epilogue operations (like bias addition) directly into reduction blocks. * **Optimization Enablement**: This fusion enables leveraging hardware-specific instructions (e.g., MACC) for bias accumulation, leading to improved performance and more efficient hardware utilization. * **IR Transformation**: The primitive transforms a two-block pattern (reduction followed by an epilogue) into a single, optimized reduction block by modifying its initialization statement and removing intermediate buffers. * **Comprehensive Implementation**: Includes C++ backend logic (`ReductionEpilogueFuser`, `SingleBlockFusionReplacer`), FFI bindings, a Python API with clear documentation, and extensive test cases to ensure correctness and functionality. <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>`.
