Worked on the espressif/llvm-project repository to enhance the NVPTX backend, focusing on maintainability and correctness in code generation. Addressed naming consistency by aligning parameter names in NVPTXISelDAGToDAG.cpp with LLVM conventions, improving code readability without altering functionality. Resolved a load-addressing bug by implementing a recursive root address finder and offset accumulator, ensuring symbol-based loads are correctly mapped even when DAG combines are disabled. These changes reduced the risk of illegal PTX instructions and improved backend stability across optimization modes. Utilized C++, LLVM IR, and low-level optimization techniques to deliver robust and maintainable compiler infrastructure improvements.
