Worked on the Halide/Halide repository, focusing on improving the correctness of intermediate representation (IR) equality checks. Addressed a bug in the graph_equal() function within IREquality.h, ensuring that the correct implementation is dispatched when comparing statements and expressions. This targeted fix, implemented in C++, prevents incorrect graph comparisons and enhances the reliability of IR equality checks, which is critical for downstream optimizations. The work involved precise debugging, risk-managed code updates, and thorough code review. Demonstrated skills in C++ and software development, contributing a small but impactful change that improves the robustness of the codebase without introducing new features.
