Implementing such bi-directional mappings is feasible for languages with a low abstraction level (e. g., C). However, language workbenches support language stacking with a bottom-up approach from low- to high-level (e. g., domain-specific) languages. This way, generation of code written with these high-level languages is incremental. However, languages can have more than one generator, which is selected depending on the execution environment. On the other hand, provision of such flexibility makes multi-level debugging much harder. In this paper, we present an approach on how to enable debugging for such multi-staged generation environments. The approach is illustrated by mbeddr, which is an extensible C language. 2015-01-01T00:00:00Z http://dl.gi.de/handle/20.500.12116/40811 Performance Tuning of PDG-based Code Clone Detection Görg, Torsten This paper provides several ideas how to improve the performance of PDG-based code clone detection techniques. We suggest an efficient way to handle the subgraph isomorphism problem without losing precision and present an algorithm that avoids the unnecessary matching effort for subclones of larger clones. 2015-01-01T00:00:00Z http://dl.gi.de/handle/20.500.12116/40812 A Methodology for Impact Analysis Based on Model Differencing Müller, Klaus; Rumpe, Bernhard 2015-01-01T00:00:00Z
