Subject: nir: Store PatchInputsRead and PatchOutputsWritten in nir_shader_info.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=db54673b54ee7e2c49d5aa6f77d2fff3eed0aa24;p=mesa.git

nir: Store PatchInputsRead and PatchOutputsWritten in nir_shader_info.

These tessellation shader related fields need plumbing through NIR.

v2: Use uint32_t instead of uint64_t to match the source type of
    GLbitfield (caught by Iago Toral).
