Yunse worked on the glu-lang/glu repository, focusing on improving the correctness and maintainability of the intermediate representation (IR) in a compiler project. During this period, Yunse addressed a bug in the UnreachableInstruction by updating its operand count from one to zero, ensuring the instruction accurately reflects its role as the terminal operation in a basic block. The work also involved simplifying the related API by removing an unnecessary value parameter from the constructor. Using C++ and applying low-level programming skills, Yunse’s targeted changes laid a foundation for more robust IR passes and contributed to cleaner, more consistent compiler infrastructure.
