Bridging the Gap Between Legacy Procedural Code and the Automated Extraction of Design

Automated design extraction from object-oriented source code has been demonstrated in the System for Pattern Query and Recognition, a static analysis tool and accompanying Elemental Design Pattern definitions that can identify instances of known design patterns in a flexible manner. SPQR concentrates on the concepts embodied in code instead of the constructs that form the code. This paper demonstrates an extension of this concept-based approach to embedded procedural code. Various common idioms in the C language are mapped to object semantics. The resulting model is then analyzed by SPQR. Presented are the results of applying a tool implementing this new concept to a production firmware codebase, with results and new predictive metrics of maintainability of code.
