Worked on strengthening the test infrastructure for the intel/intel-graphics-compiler repository by updating the LIT test suite to support opaque pointers, addressing compatibility issues with vectorizer tests and aligning with modern LLVM semantics. Focused on resolving test fragility, the work involved fixing failures related to opaque-pointer handling, which stabilized vectorizer-related tests and reduced flaky behavior across continuous integration runs. Utilized skills in LLVM, compiler development, and testing to ensure the test framework accurately reflected current opaque-pointer requirements. This targeted bug fix improved the reliability of automated testing, supporting ongoing development and maintenance of the compiler’s evolving codebase.
