When a function/method use a parameter with "ns_consumed" attribute, ensure that the mangled name is the same whether -fobjc-arc is used or not. Since "ns_consumed" attribute is generally used to inform ARC that a function/method does sink the reference, it mean it is usually implemented in a compilation unit compiled without -fobjc-arc but used form a compilation unit compiled with it. Originally found while trying to use "ns_consumed" attribute in an Objective-C++ file in Chromium (http://crbug.com/599980) where it caused a linker error. Regression introduced by revision 262278 (previously the attribute was incorrectly not part of the mangled name). Patch from Sylvain Defresne <sdefresne@chromium.org>! http://reviews.llvm.org/D20113 llvm-svn: 270702
