Description Eric Anholt 2012-10-17 19:29:15 UTC

Command line:

oglconform -minFmt -s -v 3 -1 vertexshader advanced.TestLightsTwoSided

It used to pass before the heuristics for loop unrolling were improved, then suffered a period of crashing due to lack of VS live interval analysis before reaching today's state of just failing.  If you force unrolling again by changing maxiterations of loop unrolling from 32 to 1024, it passes.

Works on 9.1 and master now.
