Classification of PVS-Studio warnings according to the standards: MISRA C, MISRA C++

MISRA C and MISRA C++ are standards of software development, created by the MISRA (Motor Industry Software Reliability Association) organization. The purpose of these standards is to improve security, portability and reliability of programs for embedded systems.

The analyzer is oriented to the latest versions of the standards: MISRA C:2012 and MISRA C++:2008.
