New checks in core cppcheck:

  • missing return in function
  • writing overlapping data, detect undefined behavior
  • compared value is out of possible type range
  • [perf] Copy elision optimization can't be applied for return std::move(local)
  • file can not be opened for read and write access at the same time on different streams

Various improvements:

  • Color output for diagnostics are added for unix-based platforms.
  • Added symbolic analysis for ValueFlow. A simple delta is used to compute the difference between two unknown variable.
  • Rules using the "define" tokenlist can also match #include as well.
  • Library <function> tags can now use <container> tag, so free functions that accept containers such as std::size, std::empty, std::begin, std::end, etc. can specify the yields or action for the container.
  • Library <smart-pointer> tag can specify a <unique> tag for smart pointers that have unique ownership. Cppcheck now warns about dangling references to smart pointers with unique ownership.
  • Fixed problems when --cppcheck-build-dir is used, that should now work better. It is recommended to use --cppcheck-build-dir to speedup Cppcheck analysis.
  • htmlreport can now output author information (using git blame)
  • More warnings about variables that is not const but can be const

Misra C 2012 compliance has been "completed"
All Misra C 2012 rules have been implemented except 1.1 , 1.2 and 17.3. Including the rules in amendment 1 and amendment 2.
