Clang-Tidy

Clang-Tidy is an open-source static analysis tool for C, C++, and Objective-C, developed as part of the LLVM project.

It integrates seamlessly with the Clang compiler front-end, enabling deep static analysis of the code. Clang-Tidy can be used to check coding standards such as those derived from MISRA C++, CERT C++, or internal guidelines.

Its primary purpose is to help developers improve code quality, maintainability, and correctness by identifying and suggesting fixes for problematic code patterns.

In safety-relevant development in automotive (ISO 26262), industrial automation (IEC 61508), and avionics (DO-178C), static code analysis is required by the corresponding safety standards. Clang-Tidy is an open-source solution that can help perform static code analysis. It offers a variety of built-in checks and can also be extended to meet project needs. Clang-Tidy helps prevent common programming errors that could lead to system malfunctions or hazardous situations.

If Clang-Tidy is used in safety-relevant development according to safety norms like ISO 26262, it must undergo qualification in accordance with the corresponding norm to demonstrate its suitability and reliability. Although Clang-Tidy is open-source and not qualified out of the box, it can be integrated into a qualified toolchain through qualification processes or by using a qualification kit that supports compliance.

Since Clang-Tidy is open-source software, it does not support commercial coding standards such as MISRA C, MISRA C++, and AUTOSAR C++14 out of the box, but it can be extended with checks for those standards. According to safety norms such as ISO 26262, tool qualification of Clang-Tidy is required. We can provide support in extending Clang-Tidy to meet the project’s needs.
