Alexander Kornienko	246e85ddb0	Don't offer '[[clang::fallthrough]];' fix-it when a fall-through occurs to a ... switch label immediately followed by a 'break;'. llvm-svn: 157508	2012-05-26 00:49:15 +00:00
Richard Smith	84837d5b5a	Add -Wimplicit-fallthrough warning flag, which warns on fallthrough between ... cases in switch statements. Also add a [[clang::fallthrough]] attribute, which can be used to suppress the warning in the case of intentional fallthrough. Patch by Alexander Kornienko! The handling of C++11 attribute namespaces in this patch is temporary, and will be replaced with a cleaner mechanism in a subsequent patch. llvm-svn: 156086	2012-05-03 18:27:39 +00:00
