Switch statements without a default case can lead to unexpected behavior and incomplete handling of all possible cases. When a switch statement lacks a default case, if a value is encountered that does not match any of the -specified cases, the program will continue execution without any defined -behavior or handling. +specified cases, the switch statement will do nothing and the program will +continue execution without handling the value. This check helps identify switch statements that are missing a default case, allowing developers to ensure that all possible cases are handled properly. _______________________________________________ cfe-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
