Worked on enhancing debugging reliability for the LLVM/RISC-V backend in the espressif/llvm-project repository, focusing on improving stack-frame accuracy and source-level traceability. Introduced propagation of FrameSetup and FrameDestroy MIFlags through stack-slot operations, enabling precise marking of prologue and epilogue instructions. Addressed issues with epilogue_begin debug line table mappings by ensuring correct flag settings on callee-saved spills and reloads, which improved call frame information and source line mapping for RISC-V builds. The work was implemented in C++ and LLVM IR, leveraging skills in compiler development, low-level systems programming, and debugging information generation to lay groundwork for future instrumentation.
