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`

			`// CC qualifier can be applied only to functions`
Standardize the parsing of function type attributes in a way that follows (as conservatively as possible) gcc's current behavior: attributes written on return types that don't apply there are applied to the function instead, etc. Only parse CC attributes as type attributes, not as decl attributes; don't accepet noreturn as a decl attribute on ValueDecls, either (it still needs to apply to other decls, like blocks). Consistently consume CC/noreturn information throughout codegen; enforce this by removing their default values in CodeGenTypes::getFunctionInfo(). llvm-svn: 95436 2010-02-06 05:31:56 +08:00			`int __attribute__((stdcall)) var1; // expected-warning{{'stdcall' only applies to function types; type here is 'int'}}`
			`int __attribute__((fastcall)) var2; // expected-warning{{'fastcall' only applies to function types; type here is 'int'}}`
