Description Karthik Hariharakrishnan 2010-03-23 11:38:16 UTC 
The MESA GL implementation fails OpenGL ES conformance test 
GL/step/step_float_frag_xvary_edgeconsthalf.test.

The generated output doesnt match the expected output generated using
step_float_frag_xvary_edgeconsthalf_ref.frag

Is this still an issue with latest Mesa? The GLSL compiler has been completely rewritten.
Comment 4 Ian Romanick 2011-03-03 13:37:35 UTC 
This test passes here on swrast and the i965 driver.  Closing.
