* nir/lower_double_ops: fixup for new nir_foreach_block()Jason Ekstrand2016-05-051-23/+9

* nir/lower_double_ops: lower mod()Samuel Iglesias Gonsálvez2016-05-041-0/+29
| | | | | | | | | | | There are rounding errors with the division in i965 that affect the mod(x,y) result when x = N * y. Instead of returning '0' it was returning 'y'. This lowering pass fixes those cases. Signed-off-by: Samuel Iglesias Gonsálvez <siglesias@igalia.com> Reviewed-by: Jordan Justen <jordan.l.justen@intel.com>
