[Mesa-dev] [PATCH 00/24] Support for ARB_shader_atomic_counters.

[Francisco Jerez]

This patch series implements support for the
ARB_shader_atomic_counters extension, which is part of GL core since
GL 4.2.  It includes patches adding support for the new APIs and GLSL
language features, and working back-end code for Intel Gen7 hardware
-- Ivy Bridge should work with these patches alone, Haswell is going
to need a small kernel change I'll probably submit for review during
the next week.

The series depends on Ken's surface state tidying patches [1] and
on patches 1-4, which are seemingly unrelated fixes.

There's also a series of ~30 unit tests for this extension I will send
to the piglit mailing list soon.

Thanks.
