He and some students had planned to or have looked at llvm's analyzer but this should be an easy step. The question on all these types analysis tools is how to manage the output. As a project, we do Coverity runs on leon3 for consistency. BSP doesn't matter for you if you want to pick at issues. But if it has warnings now, this will only increase the number. And it would be nice to think in terms of having automated reports available for the community and a scoreboard of some sort to track progress. But honestly, I've been reporting on warnings and analysis issues for years. Sometimes filing tickets. Sometimes fixing. It is an endless quest and hard to get broad help. In fairness, issues in common code gets fixed. Issues in random device drivers can tend to linger.
