In this paper, we evaluate the benefits of applying aspect-oriented software development techniques in the context of a large-scale industrial embedded software system implementing a number of crosscutting concerns. Additionally, we assess the feasibility of automatically extracting these crosscutting concerns from the source code. In order to achieve this, we present an approach for reverse engineering aspects from an ordinary application automatically. This approach incorporates both a concern verification and an aspect construction phase. Our results show that such automated support is feasible, and can lead to significant improvements in source code quality.
