<pre>As I said previously I see hangs on Total War: Napoleon” and “Total War:
Empire” traces on BDW with Mesa 10.6. I tried to revert commit "nir: Recognize
(a < c || b < c) as min(a, b) < c." but without success.
So I tried to removed all optimizations in nir_opt_algebraic.py:
no hangs were observed on “Total War: Napoleon”
hangs were still observed on “Total War: Empire”.
Somehow NIR optimizations from nir_opt_algebraic.py lead to hangs in “Total
War: Napoleon”. Looks like Pavel Ondračka observed the similar issue with
"Total War: Shogun2".</pre>
