It would continue to be defined as-is, without direct reference to the __builtin_bswap functions. But you're right that the generic code would depend on the bswap optimization pass that recognizes the mask/shift/or pattern and converts it to the builtins internally. What if we kept the ppc ifdefs, but converted the rest to the gcc generic code? r~
