PC-Lint

PC-Lint is a static analysis tool used primarily for C and C++ code. Developed by Gimpel Software, it analyzes source code to detect potential errors, bugs, stylistic issues, and violations of coding standards. It operates by parsing the code and performing checks based on a wide range of rules and heuristics. These checks go beyond the basic syntax and type checking performed by a compiler, looking for more subtle issues that could lead to runtime problems, security vulnerabilities, or decreased code maintainability.

The tool identifies potential problems such as memory leaks, null pointer dereferences, buffer overflows, unused variables, inconsistent function declarations, and violations of MISRA C/C++ standards. It can also enforce custom coding standards and guidelines specific to a project or organization. PC-Lint works by simulating the execution of the code and tracking the state of variables and pointers, allowing it to detect errors that might not be apparent during normal compilation or testing.

PC-Lint is typically used as part of a software development process to improve code quality and reduce the likelihood of defects in production. The results of the analysis are presented as a report containing warnings and error messages, which developers can then use to fix the identified issues. The tool is highly configurable, allowing users to customize the rules and checks to suit their specific needs and coding practices. While Gimpel Software is no longer actively marketing PC-Lint, it is still used in legacy projects and in contexts where its particular features and approach are preferred. Its functionality is now largely encompassed and often surpassed by modern static analysis tools that are more actively developed and integrated into modern IDEs and build systems.
