During September 2025, contributed to the intel/llvm repository by developing and integrating a new Clang-Tidy check called google-runtime-float. This feature was designed to flag uses of the long double type in C++ code, addressing portability concerns across platforms with inconsistent long double support. The approach leveraged static analysis and compiler tooling to enforce Google-style numeric type usage, thereby reducing cross-platform risk in critical numeric paths. Work focused on C++ and CMake, emphasizing code quality and maintainability. No major bugs were fixed during this period, but the contribution deepened static analysis coverage and standardized numeric practices within the LLVM project.
