Ah ok. Now I see that it's called much later, either in the driver or in
glsl_to_tgsi. Before commit 2f4fe151681 it used to be called inside the high
level IR optimization loop.


I ran this on the i965 driver with current Mesa master, and it ran just

Right, it probably does not happen anymore now
that do_vec_index_to_cond_assing is called much later in the process. Move
along, nothing to see here!
