...d. The current forms of the saturating intrinsics extend into a higher type, which can be awkward to deal with in some cases (i64's are often not legal types, for example). The intrinsic seems to produce as good or better code in almost all the cases I have tried (partly thanks to patches like D68643 and the many other optimisation over the years into the backend to efficiently optimise these saturating intrinsics, even when they are not natively available.) As noted in the review, this does bring up the question of what we should consider canonical. I believe that these intrinsics should be (...
