2011-03-08Fix my earlier commit to work with escaped newlines and leave breadcrumbsJohn McCall
in case we want to make a world where we can check intermediate instantiations for this kind of breadcrumb. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127221 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-08objc_gc wants a pointer type, not a function type; give it a more appropriate John McCall
diagnostic. Also, these attributes are commonly written with macros which we actually pre-define, so instead of expanding the macro location, refer to the instantiation location and name it using the macro loc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127219 91177308-0d34-0410-b5e6-96231b3b80d8
