[cfe-commits] r72079 - /cfe/trunk/lib/CodeGen/CGObjCGNU.cpp

[Fariborz Jahanian]

Author: fjahanian
Date: Mon May 18 19:28:43 2009
New Revision: 72079

URL: http://llvm.org/viewvc/llvm-project?rev=72079&view=rev
Log:
This patch allows clang to generate code for declared properties on the GNU runtime.  As with @synchronized, this requires some extra functions that are included with other libraries (not with the GNU runtime itself) and so will cause linker errors when these are not present.
Patch by David Chisnall.
