Please remind > me if I forget. Hi Peter, I see that you've added the HWEIGHT-capitalized interfaces for compile-time constants with fce877e3. Which means, the bits in from your original patch at http://lkml.org/lkml/2010/2/4/119 need changing (or have changed already but I've missed them). IOW, where can I get the current version of that last patch so that I can base my __arch_hweightXX stuff ontop of it for testing? Thanks. -- Regards/Gruss, Boris. - Advanced Micro Devices, Inc.
