[PATCH] Early expansion of MUX instructions on Hexagon

[Quentin Colombet]

Hi Krzysztof,

Could you comment the purpose of each function?

Right now, I do not understand for instance why after you have shrunk the live-ranges to the uses, you re-extend them again to the dead defs.
I believe this becomes clear when you explain the situation you are fixing in each function :).

Thanks,
-Quentin
