re PR target/41595 (object-c++ mangled local labels are not correctly recognized.)
2009-10-06 Iain Sandoe <iain.sandoe@sandoe-acoustics.co.uk>
PR objective-c++/41595
* config/darwin.c (darwin_label_is_anonymous_local_objc_name):
New function to recognize objective c/c++ internal symbols,
including mangled ones.
* config/darwin.h (ASM_OUTPUT_LABELREF): Use
darwin_label_is_anonymous_local_objc_name to detect both
mangled and clear ObjC internal symbols.
