From looking at the patch it's unclear whether you're testing uniforms
or initializers, but the subject I would have thought we were testing
'uniform initializers' and from the filename I would have thought we
were testing uniforms.
Which is it?
Sorry for the confusion. The test accounts for both conditions. On the
current Intel driver with the initial fp64 feature turned on, a crash
is triggered when a uniform value is compared with a constant. Anyway
Tapani was able to fix this issue yesterday with some changes on top
of my initial patch. I'm not actually sure if this test is necessary
anymore.
This test is useful as it managed to trigger bad behavior, perhaps
should be entitled to be a errr 'uniform test'. I've got a bunch of
uniform initializer tests upcoming which should test only the
initializer part.
