* tgsi: rename the TGSI fragment kill opcodesBrian Paul2013-07-125-14/+14
| | | | | | | | | | | | | | | | | | | | | 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 <[email protected]>

* gallivm: do per-pixel lod calculations for explicit lodRoland Scheidegger2013-07-042-0/+3
| | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TGSI_OPCODE_IF condition had two possible interpretations: - src.x != 0.0f - Mesa statetracker when PIPE_SHADER_CAP_INTEGERS was false either for vertex and fragment shaders - gallivm/llvmpipe - postprocess - vl state tracker - vega state tracker - most old drivers - old internal state trackers - many graw examples - src.x != 0U - Mesa statetracker when PIPE_SHADER_CAP_INTEGERS was true for both vertex and fragment shaders - tgsi_exec/softpipe - r600 - radeonsi - nv50 And drivers that use draw module also were a mess (because Mesa would emit float IFs, but draw module supports native integers so it would interpret IF arg as integers...) This sort of works if the source argument is limited to float +0.0f or +1.0f, integer 0, but would fail if source is float -0.0f, or integer in the float NaN range. It could also fail if source is integer 1, and hardware flushes denormalized numbers to zero. But with this change there are now two opcodes, IF and UIF, with clear meaning. Drivers that do not support native integers do not need to worry about UIF. However, for backwards compatibility with old state trackers and examples, it is advisable that native integer capable drivers also support the float IF opcode. I tried to implement this for r600 and radeonsi based on the surrounding code. I couldn't do this for nouveau, so I just shunted IF/UIF together, which matches the current behavior.
