Description Kenneth Graunke 2016-10-07 00:31:38 UTC 
dEQP-GLES31.functional.debug.negative_coverage.callbacks.atomic_counter.atomic_precision
dEQP-GLES31.functional.debug.negative_coverage.get_error.atomic_counter.atomic_precision
dEQP-GLES31.functional.debug.negative_coverage.log.atomic_counter.atomic_precision

try to compile shaders with mediump/lowp atomic_uint variables.  It expects compilation to fail, but we let it succeed.  We likely need to raise an error.
