Atul Kulkarni developed code coverage build support for the ROCm/rccl repository, focusing on enhancing testability and quality assurance. He introduced an ENABLE_CODE_COVERAGE option within the CMake-based build system, allowing developers to enable code coverage analysis specifically in Debug builds. This required careful updates to both the CMake configuration and the install.sh script to propagate the necessary compiler and linker flags, ensuring seamless integration with existing workflows. Working primarily with C++, CMake, and shell scripting, Atul’s contribution made code coverage instrumentation opt-in and easier to use in both CI and local environments, addressing a key need for observability.
