Linking analysis and transformation tools with source-based mappings

textabstractThis paper discusses an approach to linking separate analysis and transformation tools, such that analysis results can be used to guide transformations. Our approach consists of two phases. First, the analysis tool maps its results to relevant locations in the source code. Second, a mapping in the reverse direction is performed: the analysis results expressed as source positions and data are mapped to the abstractions used in the transformation tool. We discuss a prototype implementation of this approach in detail, and present the results of a number of case studies
