Pekka, can you comment? I think you have fallback paths for vector types only at the moment? Does BRIG have mult-highpart for 64-bit integers? On 32-bit targets we won't be able to easily expand them (but on 64-bit targets it is fine). For scalar types I think we should prefer to implement a generic expansion rather than have the frontend query the backend. For vector types I am not sure. Alexander
