Subject: If Clang is looking for an Objective-C method on
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c83e3410752adb01ec6672f819d4cd0c2e30d8cc;p=platform%2Fupstream%2Fllvm.git

If Clang is looking for an Objective-C method on
a type, and we find it in the origin for that
type, don't look anywhere else; just report it.
