Richard Smith	2868a736f8	Add a -Wclass-varargs to warn on objects of any class type being passed through an ellipsis. Since C++11 relaxed the rules on this, we allow a lot more bad code through silently, such as: ... const char *format = "%s"; std::experimental::string_view view = "foo"; printf(format, view); In this case, not only warn about a class type being used here, but also suggest that calling c_str() might be a good idea. llvm-svn: 202461	2014-02-28 01:36:39 +00:00
