--- Comment #7 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Also the reason why it shows up in the first place is because the gimple level
tracer produces:
<bb 7>:
# iftmp.0_13 = PHI <32(3)>
value_5 = value_3 << iftmp.0_13;
packed_6 = value_5 & 8388607;
And never props the constant from the PHI node until RTL combine.
