OK. We would not usually add intrinsics like this without a strong motivating case, that could not be optimized in some other way. It is better to use target independent options when available, and inline assembly is available as a fallback if it is really needed. But I would recommend that they use normal and/or/shift operations and let us know about places the compiler isn't optimizing them as well as it could be.
