Worked on improving data file handling reliability in the clash-lang/clash-compiler repository, focusing on resolving issues with ambiguous data file resolution. Addressed build-time errors caused by duplicate source directories for font.bin by implementing a deduplication step in the path resolution process, ensuring only unique hs-source-dirs were considered. This change eliminated multiple data file conflicts and improved the maintainability of both library and simulator components. Utilized Haskell for the implementation, applying software development and testing skills to validate the solution. The work reduced data-file related failures in both CI and local builds, enhancing the overall robustness of the build process.
