Author: Kenneth Graunke <[email protected]> Date: Wed Aug 17 05:03:29 2016 -0700 nir/builder: Add bany_inequal and bany helpers. The first simply picks the bany_inequal[234] opcodes based on the SSA def's number of components. The latter implicitly compares with zero to achieve the same semantics of GLSL's any().
