* nir/lower_tex: Add support for lowering coordinate offsetsJason Ekstrand2016-07-221-0/+54
| | | | | | | | | | On i965, we can't support coordinate offsets for texelFetch or rectangle textures. Previously, we were doing this with a GLSL pass but we need to do it in NIR if we want those workarounds for SPIR-V.

| | | | | | | | This lowers sampling from YUV textures to 1) one or more texture instructions to sample each plane and 2) color space conversion to RGB. Reviewed-by: Jordan Justen <jordan.l.justen@intel.com> Reviewed-by: Jason Ekstrand <jason@jlekstrand.net>

| | | | | | | | | Not sure how coverity arrives at the conclusion that we can read comp[j] unitialized (around line 204), other than not being aware that ncomp is greater than 1 so it won't underflow in the 'if (tex->is_array)' case.

* nir: Separate texture from sampler in nir_tex_instrJason Ekstrand2016-02-091-3/+3
| | | | | | | | | | | | | This commit adds the capability to NIR to support separate textures and samplers. As it currently stands, glsl_to_nir only sets the texture deref and leaves the sampler deref alone as it did before and nir_lower_samplers assumes this. Backends can still assume that they are combined and only look at only at the texture index. Or, if they wish, they can assume that they are separate because nir_lower_samplers, tgsi_to_nir, and prog_to_nir all set both texture and sampler index whenever a sampler is required (the two indices are the same in this case).

* nir/tex_instr: Rename sampler to textureJason Ekstrand2016-02-091-6/+6
| | | | | | | | | We're about to separate the two concepts. When we do, the sampler will become optional. Doing a rename first makes the separation a bit more safe because drivers that depend on GLSL or TGSI behaviour will be fine to just use the texture index all the time.
