> [..] My main point was just that the existing select instruction is not sufficient as the second operation, for essentially the same reason why the VP intrinsics have an EVL argument instead of just the mask. Creating a VP equivalent of select (as already sketched in the other thread) resolves that concern just as well.
I agree. The prototype has defined such an `llvm.vp.select` from the get-go.
