Author: Kenneth Graunke <[email protected]> Date: Tue Oct 18 15:04:37 2011 -0700 glsl: Short-circuit lower_if_to_cond_assign when MaxIfDepth is UINT_MAX. Setting MaxIfDepth to UINT_MAX effectively means "don't lower anything." Explicitly checking for this common case allows us to avoid walking the IR, computing nesting levels, and so on.
