--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
size: 10-4, last_iteration: 10-4
  Loop size: 10
  Estimated size after unrolling: 24-8


Also adding:

                #pragma GCC unroll 4

in front of the loop in FormatHex also fixes the warning.


If we could figure out if this loop would be decent .
