Worked on the llvm/clangir repository to enhance LLDB’s statistics reporting for split-dwarf builds by introducing new instrumentation focused on DWO (Debug Information Offset) file usage. Developed and integrated counters for totalLoadedDwoFileCount and totalDwoFileCount, aligning them with the existing LLDB statistics framework to provide clearer visibility into DWO file handling. This work laid the foundation for future data-driven debugging improvements by enabling more granular tracking of debug symbol files. Utilized C++ and Python, applying skills in build systems, symbol file parsing, and unit testing to ensure robust integration and accurate reporting within the LLDB development environment.
