--- Comment #1 from Ian Romanick <idr at freedesktop.org> ---
In case it isn't obvious in the wall of shader code... these are the dumb
divides:

math intdiv(8)  g6<1>D          g4<8,8,1>D      1D              { align1 1Q
compacted };
math intdiv(8)  g7<1>D          g5<8,8,1>D      1D              { align1 2Q
compacted };
....
math intmod(8)  g12<1>D         g8<8,8,1>D      1D              { align1 1Q
compacted };
math intmod(8)  g13<1>D         g9<8,8,1>D      1D              { align1 2Q
compacted };
