Worked on the espressif/llvm-project repository, focusing on improving the stability of the Hexagon backend by addressing a critical bug in the loop idiom pass. Using C++ and LLVM IR, implemented a null-check guard to prevent a null pointer dereference that previously caused segmentation faults when the -debug flag was enabled. Developed a regression test to ensure ongoing reliability and prevent future occurrences of this issue. This targeted fix reduced crash risk in development builds, enhancing the robustness of Hexagon workflows. Demonstrated skills in compiler development, low-level optimization, debugging, and test case development through precise and maintainable code changes.
