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.
