Subject: Add parsing support in an Objective-C method declaration for attributes between
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=77755a57c9e85418626ac64c0d38975d5fa9aded;p=clang

Add parsing support in an Objective-C method declaration for attributes between
the return type and selector. Haven't hooked this up to Sema yet.
