Worked on the espressif/llvm-project repository to enhance the stability of the LLVM CodeGen backend for Hexagon, focusing on resolving a critical crash in the window scheduler. Addressed an issue where live interval checking used outdated slot indices for cloned Machine Instructions by updating the slot index map before recycling instructions. Developed a Hexagon-specific regression test to ensure the fix’s reliability and prevent future regressions. The work emphasized maintainability and correctness, aligning with LLVM CodeGen standards. Utilized C++ and Assembly, applying skills in code generation, debugging, and low-level optimization to deliver a robust solution without introducing new features this month.
