Reproduce steps:
-------------------------
1. xinit
2. bin/shader_runner generated_tests/spec/arb_shading_language_packing/execution/built-in-functions/vs-packHalf2x16.shader_test -auto
Comment 1 Ben Widawsky 2014-11-24 18:45:29 UTC 
Unlike many of the existing BDW failures, this one does still fail.
Comment 2 Ben Widawsky 2014-12-15 23:46:47 UTC 
Please test this branch:
http://cgit.freedesktop.org/~bwidawsk/mesa/log/?h=integer-multiply
Comment 3 lu hua 2014-12-16 05:38:56 UTC 
It works well on latest mesa master branch(94303a0750f9eaae3fcf598). Close it.
