> The Hexagon change is fine, although a bit surprising. The two instructions are the same, but the :raw form is generally emitted for newer CPUs. I'm not sure what changed to get the older form printed instead.

Thanks for review this. The only change from this patch is that a MOV in the entry is sunk into %b1.  Honestly, I don't have much idea about the :raw form and how the MOV impact on allocframe in Hexagon. Do you think this expose some unexpected behavior  in Hexagon?
