## Summary of Changes Hello @grf53, 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 resolves a significant `bfloat16` conversion issue within the `BF16ComputeLegalize` compilation pass. Previously, direct casting was used in certain `BufferStoreNode` scenarios, leading to incorrect data type handling and computational errors for `bfloat16` tensors. The change ensures that the appropriate `DTypeConversion` logic is applied, guaranteeing accurate `bfloat16` operations across the system. A new test case has been added to confirm the fix. ### Highlights * **bfloat16 Conversion Bug Fix**: Addresses a critical bug in the `BF16ComputeLegalize` pass where `bfloat16` tensors were incorrectly converted during `BufferStoreNode` operations, leading to erroneous computations, particularly in `nn.Linear` with `MatMul`. * **Corrected Type Conversion Logic**: The fix involves replacing a direct `cast` with `DTypeConversion()` when the stored value's data type differs from the buffer's data type, ensuring proper `bfloat16` to `float32` conversion logic is applied. * **New Test Case Added**: A new test, `test_bf16_simple_store_will_legalize`, has been introduced to validate the corrected `bfloat16` conversion behavior, specifically for simple store operations. <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>`.
