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 %s -fsyntax-only -pedantic -verify`
PR4290: Handle vfprintf in a way that doesn't give any diagnostics for valid declarations and doesn't give an error for autoconf-style invalid redeclarations. This isn't quite ideal, but I don't see any other way easy way to handle it. (The only thing I can think of that's reasonably general is adding a new builtin type FILETy which is only compatible with a type equivalent to FILE, and that seems like overkill.) llvm-svn: 72760 2009-06-03 17:54:50 +08:00			`// PR4290`
