--- Comment #7 from Marek Olšák <mar...@gmail.com> ---
"warn" is not a failure, like I said. I knew about this pass->warn change. It
actually uncovers a potential issue with the hardware - or with the test. It
depends on how you look at it.
>From the test:
* Note: some OpenGL implementations do not pass the "flat_first" and
* "flat_last" tests when rendering quads or polygons. That is, they
* produce a tessellation which contains the correct vertices, but not
* in the order required to preserve flat shaded colors. This is
* unlikely to cause problems for client programs, since client
* programs that use new features like transform feedback are unlikely
* to also use deprecated features like quads and polygons. Also, it
* is a matter of interpretation whether these tests are expected to
* pass at all--after all, the spec does say that "the order of
* tessellation within a primitive is undefined". Accordingly, these
* failures, should they occur, are flagged as warnings rather than
* failures.
However, my Mesa commit which causes this test not to pass on nouveau, radeon,
and probably other gallium drivers, and I did know about this, actually fixes
real issues with flat shading and primitive restart and therefore cannot be
reverted.
