* tgsi: collect texture sampler target info in tgsi_scan_shader()Brian Paul2016-03-291-0/+1
| | | | | | | | | | | | | | | Texture sample instructions specify a sampler unit and texture target such as "1D", "2D", "CUBE", etc. Sampler view declarations also specify the sampler unit and texture target. This patch checks that the texture instructions agree with the declarations and collects the texture target type for each sampler unit. v2: only compare instruction's texture target to the sampler view declaration target if the instruction is a TEX instruction, not a SAMPLE instruction.

* tgsi: track max array per fileRob Clark2015-01-071-0/+2
| | | | | | | | | | | | NOTE IN[] and OUT[] don't need (have?) ArrayID's.. and TEMP[] can optionally have them. So we implicitly assume that ArrayID==0 always exists for each file. This is why array_max[file] is never less than zero. You can tell from indirect_files(_read/written) if the legacy array- id zero was actually used.

* gallium: add TGSI_SEMANTIC_VERTEXID_NOBASE and TGSI_SEMANTIC_BASEVERTEXRoland Scheidegger2014-12-161-0/+2
| | | | | | | | | | | | | | | | | | | Plus a new PIPE_CAP_VERTEXID_NOBASE query. The idea is that drivers not supporting vertex ids with base vertex offset applied (so, only support d3d10-style vertex ids) will get such a d3d10-style vertex id instead - with the caveat they'll also need to handle the basevertex system value too (this follows what core mesa already does). Additionally, this is also useful for other state trackers (for instance llvmpipe / draw right now implement the d3d10 behavior on purpose, but with different semantics it can just do both). Doesn't do anything yet. And fix up the docs wrt similar values. v2: incorporate feedback from Brian and others, better names, better docs.

* tgsi: rename the TGSI fragment kill opcodesBrian Paul2013-07-121-1/+1
| | | | | | | | | | | | | | | | | | | | | TGSI_OPCODE_KIL and KILP had confusing names. The former was conditional kill (if any src component < 0). The later was unconditional kill. At one time KILP was supposed to work with NV-style condition codes/predicates but we never had that in TGSI. This patch renames both opcodes: TGSI_OPCODE_KIL -> KILL_IF (kill if src.xyzw < 0) TGSI_OPCODE_KILP -> KILL (unconditional kill) Note: I didn't just transpose the opcode names to help ensure that I didn't miss updating any code anywhere. I believe I've updated all the relevant code and comments but I'm not 100% sure that some drivers had this right in the first place. For example, the radeon driver might have llvm.AMDGPU.kill and llvm.AMDGPU.kilp mixed up. Driver authors should review their code. Reviewed-by: Jose Fonseca <jfonseca@vmware.com>
* gallivm: do per-pixel lod calculations for explicit lodRoland Scheidegger2013-07-041-0/+2
| | | | | | | | | | | | | | | | | | | | | d3d10 requires per-pixel lod calculations for explicit lod, lod bias and explicit derivatives, and we should probably do it for OpenGL too - at least if they are used from vertex or geometry shaders (so doesn't apply to lod bias) this doesn't just affect neighboring pixels. Some code was already there to handle this so fix it up and enable it. There will no doubt be a performance hit unfortunately, we could do better if we'd knew we had a real vector shift instruction (with variable shift count) but this requires AVX2 on x86 (or a AMD Bulldozer family cpu). Don't do anything for lod bias and explicit derivatives yet, though no special magic should be needed for them neither. Likewise, the size query is still broken just the same. v2: Use information if lod is a (broadcast) scalar or not. The idea would be to base this on the actual value, for now just pretend it's a scalar in fs and not a scalar otherwise (so, per-pixel lod is only used in gs/vs but same code is generated for fs as before).

* gallium: add a cull distance semanticZack Rusin2013-06-101-0/+1
| | | | | | | | | | | | | cull distance is analogous to clip distance. If a register is given this semantic, then the values in it are assumed to be a float32 distance to a plane.
