Comment 1 Nanley Chery 2015-11-30 23:13:19 UTC 
I've run this test on a CHV with,

mesa: 44944a66cef199e08f8071eb51354231ebcd10d7
piglit: 04c0045d68ce1016b3501874026ebbb8b113e8ea

and the test passes.
Comment 2 Matt Turner 2016-11-02 19:46:55 UTC 
Test passes with and without INTEL_DEBUG=vec4 on Braswell.

(Though vs-unpackHalf2x16 with INTEL_DEBUG=vec4 fails)
