This thesis develops a demand driven solver for constraint based control flow analysis. Our approach is modular, flow-sensitive and scaling. It allows to efficiently construct the interprocedural control flow graph (ICFG) for object-oriented languages. The analysis is based on the formal semantics of a Java-like language. It is proven to be correct with respect to this semantics. The base algor...

We present a new approach to information flow control (IFC), which exploits counterexample-guided abstraction refinement (CEGAR) technology. The CEGAR process is built on top of our existing IFC analysis in which illegal flows are characterized using program dependence graphs (PDG) and path conditions (as described in [12]). Although path conditions provide an already precise abstraction that c...

The ever-growing usage of aspect-oriented development methodology in the field of software engineering requires tool support for both research environments and industry. So far, tool support for many activities in aspect-oriented software development has been proposed, to automate and facilitate their development. For instance, the AJaTS provides a transformation system to support aspect-orient...
