--- Comment #2 from Gonzalo BG <gonzalobg88 at gmail.com> ---
Damn you are right, the `<4 x i32>` being used have been sign extended from `<4
x i1>` but there is currently no way to properly express that. I'm closing this
as invalid, since without being able to express that there is nothing that can
be done here.
