Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'. - This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target). llvm-svn: 91446 2009-12-16 04:14:24 +08:00			`// RUN: %clang_cc1 -fsyntax-only -verify %s`
First pass at friend semantics. llvm-svn: 78274 2009-08-06 10:15:43 +08:00
Rework the Parse-Sema interaction for friends to better support friend class templates. We now treat friend class templates much more like normal class templates, except that they still get special name lookup rules. Fixes PR5057 and eliminates a bunch of spurious diagnostics in <iostream>. llvm-svn: 82848 2009-09-26 14:47:28 +08:00			`struct B0;`

Switch diagnostic text from "C++0x" over to "C++11". We'd also like for "C++11" or "c++11" to be used for the warning groups, but without removing the old warning flags. Patches welcome; I've run out of time to work on this today. llvm-svn: 141801 2011-10-13 03:26:40 +08:00			`friend int; // expected-warning {{non-class friend type 'int' is a C++11 extension}}`
Tweak the diagnostics for the C++0x extensions to friend types to note that they are C++0x extensions, and put them in the appropriate group. We already support most of the semantics.
