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
Richard Smith	c202b2809a	Add an AttributedStmt type to represent a statement with C++11 attributes ... attached. Since we do not support any attributes which appertain to a statement (yet), testing of this is necessarily quite minimal. Patch by Alexander Kornienko! llvm-svn: 154723	2012-04-14 00:33:13 +00:00
