Author: Timothy Arceri <[email protected]> Date: Sun Aug 2 14:57:38 2015 +1000 nir: Use a single bit for the dual-source blend index The only values allowed are 0 and 1, and the value is checked before assigning. This is a copy of 8eeca7a56c that seems to have been made to the glsl ir type after it was copied for use in nir but before nir landed.
