[Mesa-dev] [PATCH 00/16] Various Vulkan/SPIR-V fixes (mostly SPIR-V)

[Jason Ekstrand]

I pulled the latest version of the Vulkan CTS and gave it a run.  One of
the major aditions was a pile of tests for different texturing operations.
This demonstrated that our texturing support was, well, sub-par.  These
patches get it most of the way fixed up.  As a nice side-benifit, it also
fixes 5 piglit tests on GL.

Jason Ekstrand (16):
  spirv/nir: Fix some texture opcode asserts
  spirv/nir: Add support for shadow samplers that return vec4
  spirv/nir: Properly handle gather components
  anv/pipeline: Set binding_table.gather_texture_start
  nir: Add a helper for determining the type of a texture source
  nir/lower_tex: Add some helpers for working with tex sources
  nir/lower_tex: Add support for lowering coordinate offsets
  i965/nir: Enable NIR lowering of txf and rect offsets
  i965: Get rid of the do_lower_unnormalized_offsets pass
  spirv/nir: Don't increment coord_components for array lod queries
  anv/image: Assert that the image format is actually supported
  spirv/nir/: Move opcode selection higher up in handle_texture
  spirv/nir: Refactor type handling in handle_texture
  nir/spirv: Refactor coordinate handling in handle_texture
  spirv/nir: Handle texture projectors
  spirv/nir: Add support for ImageQuerySamples
