I've run into the same behavior with clang and intrinsics. Well, I appreciate the fact that they're trying to optimize the intrinsics usage, there really does need to be a flag or pragma you can pass that says more along the lines of "no really, give me what I asked for." In some cases I have found that the code it produces is a significant pessimization from what I had selected.
