A GCC-based Compliance Checker for Single-translation-unit, Identifier-related MISRA-C Rules

MISRA-C is a well-defined software specification for the C programming language that gives programmers criteria to develop reliable programs. This paper implements a MISRA-C compliance checker based on the GCC compiler infrastructure. It focuses on identifier-related rules that are single-translation-unit-labeled. We describe and develop strategies for implementing the checking codes. We also discuss the rules that can be detected by existing GCC options. For the tested benchmark programs, the modified GCC compiler can correctly assess compliance with the target MISRA- C rules.
