          Priority: low
            Bug ID: 78679
          Assignee: idr at freedesktop.org
           Summary: Gen4-5 code lost: runtime_check_aads_emit
        QA Contact: intel-3d-bugs at lists.freedesktop.org
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: kenneth at whitecape.org
          Hardware: Other
            Status: NEW
           Version: git
         Component: Drivers/DRI/i965
           Product: Mesa

The c->runtime_check_aads_emit field has been unused since we removed the old
ARB_fragment_shader backend in commit 098acf6c84333edbb7b1228545e4bdb2572ee0cd.

It apparently used to control runtime checking of antialiased line stuff when
doing FB writes on Gen4-5.  Presumably, that existed for a reason, and this has
just been broken since Mesa 9.1 or so.

Someone should investigate and either fix the code, or explain why it isn't
necessary and close this as NOTABUG.
