Intel has revealed developments related to the ControlFlag research project aimed at creating a machine learning system for improving code quality. The toolkit prepared by the project allows, based on a model trained on a large amount of existing code, to identify various errors and anomalies in source texts written in high-level languages such as C / C ++. The system is suitable for detecting various kinds of problems in your code, from detecting typos and incorrect combinations of types to identifying missing checks for null values in pointers and problems with memory. The ControlFlag code is written in C ++ and is open source under the MIT license.
