[Mesa-dev] [PATCH 0/2] Implement INTEL_fragment_shader_ordering

[Manolova, Plamena]

Hi Mark,
AFAIK there is no piglit test for this specific extension. However
underneath the hood it reuses the
functionality of ARB_fragment_shader_interlock, which has a test. I believe
the only major difference between
the two extensions is that unlike beginInvocationInterlockARB,
beginFragmentShaderOrderingINTEL
can
be called from functions other than main(). If necessary it would be pretty
straightforward to reuse most of the code
for the ARB_fragment_shader_interlock test to create one
for INTEL_fragment_shader_ordering.

Thank you,
Pam
