The command line is not changed drastically. Your old cppcheck scripts should work as before.
Compiling: There is a new dependency Z3. When compiling with the Makefile it is highly recommended to use "USE_Z3=yes".
Improved clang-tidy integration
Several fixes to;
Clang is a C/C++ compiler that has a very robust and well made parser.
Cppcheck will always use its internal parser by default. However there is now an option to use the Clang parser instead.
It is recommended that you use the default internal Cppcheck parser unless you notice that it fails to parse your code properly (syntax errors, strange false alarms).
There is a new "soundy" analysis in Cppcheck that should detect most bugs. You should expect false alarms, however the false alarms will not be overwhelming.
This new "soundy" analysis is not intended to replace normal Cppcheck analysis. There are use cases where false alarms can not be tolerated.
We have added 1 checker and that checks for division by zero:
You can read more about this analysis in the "Bug hunting" chapter in the manual.
