MISRA C++2023, Build-Wrapper for macOS and Valgrind issues import

Hello dear C and C++ users

We are super happy to come to you with great news.

You can now use the Build-Wrapper with ARM macs and with macOS 13 (Ventura).
You can now import Valgrind issues. It works for both Memcheck and Hellgrind issues)

Last but not least, we are bringing MISRA C++ 2023 support with an initial batch of 43 rules!:

  • Rule M23_003: Variables with limited visibility should be used at least once

  • Rule M23_403: The ‘goto’ statement should not be used

All available MISRA C++ 2023 rules can be found here.

And because we think that MISRA C++ 2023 has value for a wider audience than the automotive industry, we added a new C++ quality profile called Mission-critical. It is actually wider than MISRA C++ 2023 and it is our recommendation for developing mission-critical software with modern C++. It will be updated with new MISRA C++ 2023 rules in the future.

These new features will be available with SonarQube 10.2 starting from Developer Edition. They will be available shortly on SonarCloud .
MISRA is already available on SonarLint.

As always, you can see what’s coming next and vote for C and C++ features you would like to see in SonarQube , SonarCloud , and SonarLint .
