Developed cross-architecture debugging capabilities for the dotnet/diagnostics repository by implementing LoongArch64 disassembly support. This work involved extending disasmLOONGARCH64.cpp to process LoongArch64 instructions, display line numbers and offsets, and accurately handle branches as well as garbage collection and exception handling information. The approach required low-level programming expertise, particularly in C++ and assembly language, to ensure correct instruction decoding and reporting. Additionally, a minor padding adjustment was made to the LOONGARCH64_CONTEXT structure to maintain alignment and accommodate future enhancements. The feature addressed the need for robust LoongArch64 support in diagnostics tooling, enhancing the repository’s cross-platform capabilities.
