PROFILE
Sun Lijun
Sun Lijun contributed to the dotnet/runtime repository by addressing a coreclr ABI issue affecting LoongArch64 support. Focusing on low-level system architecture and compiler development, Sun removed the 'tp' register from the set of callee-saved registers, updating frame handling and offset logic to match the revised calling convention. This change, implemented in C++ and Assembly, resolved incorrect save and restore operations for the 'tp' register, improving runtime stability and cross-compiler compatibility for LoongArch64 workloads. Sun validated the fix through local builds and tests, demonstrating a strong understanding of debugging and low-level programming in the context of runtime system maintenance.
