+  %in = insertelement <vscale x 4 x i32*> undef, i32* %v, i32 0
+  %splat = shufflevector <vscale x 4 x i32*> %in, <vscale x 4 x i32*> undef, <vscale x 4 x i32> zeroinitializer
----------------
Are these `undef`s supposed to be `poison` nowadays? I think I've seen both recently so it's as much for my own knowledge :)
