Bug detailed description:
-------------------------
It fails on Sandybridge(i386) with mesa master and 10.2 branch. It works well
on x86_64 machine.
It was pass in earlier our nightly testing, fails now. But I can't reproduce
the pass.
Following cases also fail:
spec_arb_shading_language_packing_execution_built-in-functions_fs-unpackSnorm4x8
spec_arb_shading_language_packing_execution_built-in-functions_fs-unpackUnorm4x8
spec_arb_shading_language_packing_execution_built-in-functions_vs-packSnorm4x8
spec_arb_shading_language_packing_execution_built-in-functions_vs-unpackSnorm4x8
spec_arb_shading_language_packing_execution_built-in-functions_vs-unpackUnorm4x8
output:
