Product line engineering is often conducted in an incremental way, in which the variability artifacts evolve in the space, the time, as well as the asset dimension. In order to cope with the evolution of the variability, the VITAL approach and tool have been developed and used in different industrial settings to analyze variability realizations relying on the C preprocessor. Over the last decade, further promising analysis approaches and tools have been developed. To understand, if and how they could enhance the VITAL approach, we have conducted an analysis of promising technologies. In this paper, we share some of our findings along our comparative study on variability code analysis technologies. As we have conducted the study in the light of the intended VITAL enhancement, the study does not claim completeness. Nevertheless, we believe that the findings can help researchers and industrial practitioners to gain an overview and find entry points for their own investigations.
