## Summary of Changes Hello @MasterJH5574, 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 addresses a critical issue where empty variable names could be generated, leading to compilation failures in GPU code. It introduces a robust mechanism to default empty names to 'v' and corrects the logic for applying prefixes to these names. A new test case has been added to validate this behavior, ensuring the system produces valid and unique variable names even when provided with empty inputs. ### Highlights * **Empty Variable Name Handling**: The `FreshName` function in `NameSupplyNode` now explicitly checks for empty input names and, if found, reassigns them to the default variable name 'v' to prevent the generation of invalid empty variable names in GPU code. * **Prefixing Logic Correction**: The `add_prefix_to_name` call within `FreshName` has been updated to use the potentially remapped `unique_name` instead of the original input `name`. This ensures that prefixes are applied correctly, especially when the original name was empty and remapped to 'v'. * **New Test Case**: A new Python test `test_fresh_name_empty_string` has been added to verify that the `NameSupply` correctly handles empty input strings, producing 'v' for the first instance and 'v_1' for subsequent requests, ensuring uniqueness. 🧠**New Feature in Public Preview:** You can now enable **Memory** to help **Gemini Code Assist** learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. **Click [here](https://codeassist.google/code-review/login) to enable Memory in your admin console.** <details> <summary><b>Changelog</b></summary> * **src/ir/name_supply.cc** * Modified `NameSupplyNode::FreshName` to map empty input `name` to 'v' before further processing. * Updated the call to `add_prefix_to_name` within `FreshName` to use the `unique_name` variable (which might have been remapped from an empty string) instead of the original `name`. * **tests/python/ir/test_name_supply.py** * Added a new test file. * Implemented `test_fresh_name_empty_string` to verify that `NameSupply.fresh_name` correctly handles empty string inputs, returning 'v' and 'v_1' for successive calls. </details> <details> <summary><b>Activity</b></summary> * No human activity has been recorded on this pull request yet. </details> <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>`.
