[Mesa-dev] [PATCH v3 00/30] Nir support for Nouveau

[Karol Herbst]

significant changes to last series:
* disable support for 64 bit types
* fix tessellation shader bugs
* assume vec4 elements for variable index arrays (MemoryOpts workaround)

piglit run -x glx -x egl -x streaming-texture-leak -x max-texture-size tests/gpu.py:
[26010/26010] skip: 10410, pass: 15386, warn: 9, fail: 191, crash: 14

remaining issues:
* transform feedback with geometry shaders
* indirects in image_load/store
* interpolateAt
* getting 64 bit types to work. This is mainly limited by codegen RA being
  not able to handle those correctly, because from_TGSI just generates merge
  and splits and doesn't hit the faulty paths.
