I think you should not explicitly exclude cases that are covered by "-Wunsequenced". It's okay for check to have duplicate functionality with compiler flags. Moreover, for gcc there is "-Wsequence-point" and we don't know to what extent "-Wunsequenced" can find bugs, so It's better just to mention that functionality of this check may overlap with existing compiler flags such as "-Wunsequenced", "-Wsequence-point". https://github.com/llvm/llvm-project/pull/130421 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
