[Mesa-dev] [PATCH V4 0/6] i965 ARB_gpu_shader5 interpolateAt*

[Chris Forbes]

After a bunch of experiments with lowering schemes, I've come full circle, back to pretty much the same design as the RFC patches sent out some time ago.

This series adds support for the ir_*_interpolate_at_* expression types in the i965 driver. The corresponding glsl parts have already landed.

Big changes:
- Just generally tidier!
- Low-level support is updated to use the new brw_inst API.
