* nir: update opcode definitions for different bit sizesConnor Abbott2016-03-171-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some opcodes need explicit bitsizes, and sometimes we need to use the double version when constant folding. v2: fix output type for u2f (Iago) v3: do not change vecN opcodes to be float. The next commit will add infrastructure to enable 64-bit integer constant folding so this is isn't really necessary. Also, that created problems with source modifiers in some cases (Iago) v4 (Jason): - do not change bcsel to work in terms of floats - leave ldexp generic Squashed changes to handle different bit sizes when constant folding since otherwise we would break the build. v2: - Use the bit-size information from the opcode information if defined (Iago) - Use helpers to get type size and base type of nir_alu_type enum (Sam) - Do not fallback to sized types to guess bit-size information. (Jason) Squashed changes in i965 and gallium/nir drivers to support sized types. These functions should only see sized types, but we can't make that change until we make sure that nir uses the sized versions in all the relevant places. A later commit will address this.

* nir: Add a bit_size to nir_register and nir_ssa_defJason Ekstrand2016-03-171-0/+6
| | | | | | | | | | | | | | | | | | | | | This really hacky commit adds a bit size to registers and SSA values. It also adds rules in the validator to validate that they do the right things. It's still an open question as to whether or not we want a bit_size in nir_alu_instr or if we just want to let it inherit from the destination. I'm inclined to just let it inherit from the destination. A similar question needs to be asked about intrinsics. v2 (Connor): - Relax validation: comparisons have explicit destination sizes and implicit source sizes. v3 (Sam): - Use helpers to get size and base types of nir_alu_type enum.

* nir: Remove the const_offset from nir_tex_instrJason Ekstrand2016-02-101-3/+0
| | | | | | | | | | | When NIR was originally drafted, there was no easy way to determine if something was constant or not. The result was that we had lots of special-casing for constant values such as this. Now that load_const instructions are SSA-only, it's really easy to find constants and this isn't really needed anymore.

* nir: Separate texture from sampler in nir_tex_instrJason Ekstrand2016-02-091-1/+30
| | | | | | | | | | | | | 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 Ekstrand2016-02-091-12/+12
| | | | | | | | | 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.

* nir: const_index helpersRob Clark2016-02-091-2/+62
| | | | | | | | | | | | | | Direct access to intr->const_index[n], where different slots have different meanings, is somewhat confusing. Instead, let's put some extra info in nir_intrinsic_infos[] about which slots map to what, and add some get/set helpers. The helpers validate that the field being accessed (base/writemask/etc) is applicable for the intrinsic opc, for some extra safety. And nir_print can use this to dump out decoded const_index fields.
