In system software, programs are usually developed as software product families. This enables developers to tailor their programs to different use cases while maintaining only a single code base. However, these synergy effects are only utilized for the source code itself. The following steps in the software life cycle, building, testing, and deploying, are performed for each configuration independently, resulting in poor scalability and enormous costs.

Therefore, we developed multiple tools, each solving the problem for a different step in the software life cycle. Some of the tools are stand-alone, others are implemented as plugins for LLVM.

The goal of this thesis is to integrate these tools into a toolchain utilizing synergy effects between them and improving scalability, efficiency, and effectiveness even further. This can be evaluated by applying the toolchain to various C/C++ open-source software projects.
