<pre>Ok, I finished the bisection:
8b5749f65ac434961308ccb579fb8a816e4f29d5 is the first bad commit
commit 8b5749f65ac434961308ccb579fb8a816e4f29d5
Author: Kenneth Graunke <<a href="mailto:kenneth@whitecape.org">kenneth@whitecape.org</a>>
Date: Sun Nov 15 04:37:50 2015 -0800
glsl: Override the # of varying slots for ClipDistance and TessLevel*.
Right now, this shouldn't have any effect, as all drivers use
LowerClipDist and LowerTessFactors to turn the float[] arrays into
vectors.
However, it should help make it possible for drivers to avoid that
lowering.

I verified this is really the first bad commit by building 1edc53a66b with
8b5749f65a reverted and that gave me a working SDDM again.</pre>
