[Mesa-dev] [PATCH 00/15] Clover: support CL through SPIR-V

[Karol Herbst]

MR on gitlab: https://gitlab.freedesktop.org/mesa/mesa/merge_requests/563

Due to some nouveau and other random bits I thought it makes sense to post
this series on the Mailing List as well.

In short, this series adds support for providing OpenCL through spirv by
using the spirv-llvm-translator library to convert llvm to spirv.

Karol Herbst (10):
  nv50/ir/nir: parse system values first and stop for compute shaders
  nv50/ir/nir: don't assert on !main
  nv50/ir/nir: handle kernel inputs
  nv50/ir/nir: implement load/store_global
  gallium: add blob field to pipe_llvm_program_header
  rename pipe_llvm_program_header to pipe_binary_program_header
  nir/spirv: add spirv_to_nir_cl
  gallium: add entry_point field to pipe_compute_state
  clover: add support for consuming spirv
  nvc0: expose spirv support

Pierre Moreau (5):
  meson: Check for SPIRV-Tools and llvm-spirv
  clover/spirv: Add functions for validating SPIR-V binaries
  clover/spirv: Add functions for parsing arguments, linking programs,
    etc.
  clover/llvm: Add options for dumping SPIR-V binaries
  clover/llvm: Add functions for compiling from source to SPIR-V
