Worked on enhancing the correctness and portability of the LoongArch64 backend in the dotnet/runtime repository, focusing on low-level system architecture and compiler development. Addressed a coreclr ABI issue by removing the tp register from the set of callee-saved registers, updating frame handling and offset logic to align with the revised calling convention. Utilized Assembly and C++ to implement and validate these changes, ensuring that save and restore operations no longer incorrectly handle the tp register. This targeted bug fix improved runtime stability and cross-compiler compatibility for LoongArch64 applications, supporting enterprise workloads and reducing potential errors in register management.
