(In reply to Michel Dänzer from comment #34)
I can't reproduce random failures with glsl-fs-min nor any piglit regressions with sub-register liveness enabled, but sub-register liveness doesn't seem to result in any code difference for glsl-fs-min anyway.
I can't too if i run it alone, so there is no difference, it just fail sometimes in full piglit run.
Can you find another test which consistently passes without sub-register liveness and fails with it *and* shows a difference between them in the R600_DEBUG=vs,ps stderr output, and attach the latter for both cases?
As i said yesterday comment 33 i trimmed down only ones which shows this regression, you can pick any of those 136 test which shows difference. Let say:
R600_DEBUG=vs,ps ./bin/copy-pixels -samples=8 -auto
Outputs attached, first without...
