A Coding Rule Conformance Checker Integrated into GCC

AbstractCoding rules are often used in industry to foster best practices when coding software and to avoid the many hazardous constructions present in languages such as C or C++. Predictable, reliable tools are needed to automatically measure adherence to these practices, as manually checking for compliance is cumbersome. Moreover, due to the wide range of possible coding rule sets, easy of customization is a need in order for these tools to be of practical use. With this aim in mind, we present an extension of the GNU Compiler Collection (GCC) that flags those code fragments that do not conform to coding rules belonging to a given set. These sets of coding rules can be defined using a high-level declarative language based on logic programming, thereby making it possible to easily check code for conformance with respect to rules addressing the particular needs of a project, company, or application area
