It fails on BSW/SKL with mesa master branch, works well on 10.4 branch.
l_sp.c and l_sep.c also fail with the same bisect commit.

Bisect shows: 2335153ff2fae01d6294876a86d3eab59c6c4236 is the first bad commit

It also fails on BDW.
Comment 3 Matt Turner 2015-02-12 02:19:15 UTC 
Patch on the list.
Comment 4 Ben Widawsky 2015-02-15 17:42:58 UTC 
Matt, you need to change the status to NEEDINFO. Also, it would help if you provided a link for QA.

I wasn't waiting on QA. And it's in the URL field.
Comment 6 Matt Turner 2015-02-15 20:26:53 UTC 
I didn't realize it, but this one did actually get reviewed, so I've now committed it as:

    i965/vec4/vp: Use vec4_visitor::CMP.

Should all be fixed now. Thanks!
