2020-05-27shader/other: Implement MEMBAR.CTSReinUsesLisp
This silences an assertion we were hitting and uses workgroup memory barriers when the game requests it.

shader/other: Implement BAR.SYNC 0x0
2020-05-21shader/other: Implement BAR.SYNC 0x0ReinUsesLisp
Trivially implement this particular case of BAR. Unless games use OpenCL or CUDA barriers, we shouldn't hit any other case here.
2020-05-21shader/other: Implement thread comparisons (NV_shader_thread_group)ReinUsesLisp
Hardware S2R special registers match gl_Thread*MaskNV. We can trivially implement these using Nvidia's extension on OpenGL or naively stubbing them with the ARB instructions to match. This might cause issues if the host device warp size doesn't match Nvidia's. That said, this is unlikely on proper shaders. Refer to the attached url for more documentation about these flags. https://www.khronos.org/registry/OpenGL/extensions/NV/NV_shader_thread_group.txt
2020-05-09shader_ir: Separate float-point comparisons in ordered and unorderedReinUsesLisp
This allows us to use native SPIR-V instructions without having to manually check for NAN.

shader/texture: Support multiple unknown sampler properties

2020-04-23shader_ir: Turn classes into data structuresReinUsesLisp
2020-04-06shader/memory: Implement RED.E.ADDReinUsesLisp
Implements a reduction operation. It's an atomic operation that doesn't return a value. This commit introduces another primitive because some shading languages might have a primitive for reduction operations.

2020-02-01Merge pull request #3282 from FernandoS27/indexed-samplersbunnei
Partially implement Indexed samplers in general and specific code in GLSL
2020-01-26shader/memory: Implement ATOM.ADDReinUsesLisp
ATOM operates atomically on global memory. For now only add ATOM.ADD since that's what was found in commercial games. This asserts for ATOM.ADD.S32 (handling the others as unimplemented), although ATOM.ADD.U32 shouldn't be any different. This change forces us to change the default type on SPIR-V storage buffers from float to uint. We could also alias the buffers, but it's simpler for now to just use uint. While we are at it, abstract the code to avoid repetition.

2019-12-30Shader_IR: add the ability to amend code in the shader ir.Fernando Sahmkow
This commit introduces a mechanism by which shader IR code can be amended and extended. This useful for track algorithms where certain information can derived from before the track such as indexes to array samplers.

Implement FLO & TXD Instructions on GPU Shaders
2019-11-22shader/texture: Deduce texture buffers from lockerReinUsesLisp
Instead of specializing shaders to separate texture buffers from 1D textures, use the locker to deduce them while they are being decoded.

2019-10-29shader/node: Unpack bindless texture encodingReinUsesLisp
Bindless textures were using u64 to pack the buffer and offset from where they come from. Drop this in favor of separated entries in the struct. Remove the usage of std::set in favor of std::list (it's not std::vector to avoid reference invalidations) for samplers and images.
2019-10-15shader/node: std::move Meta instance within OperationNode constructorLioncash
Allows usages of the constructor to avoid an unnecessary copy.
2019-09-21gl_shader_decompiler: Use uint for images and fix SUATOMReinUsesLisp
In the process remove implementation of SUATOM.MIN and SUATOM.MAX as these require a distinction between U32 and S32. These have to be implemented with imageCompSwap loop.
2019-09-21shader/image: Implement SULD and remove irrelevant codeReinUsesLisp
* Implement SULD as float. * Remove conditional declaration of GL_ARB_shader_viewport_layer_array.

2019-09-05shader_ir: Implement ST_SReinUsesLisp
This instruction writes to a memory buffer shared with threads within the same work group. It is known as "shared" memory in GLSL.
2019-08-21shader_ir: Implement VOTEReinUsesLisp
Implement VOTE using Nvidia's intrinsics. Documentation about these can be found here https://developer.nvidia.com/reading-between-threads-shader-intrinsics Instead of using portable ARB instructions I opted to use Nvidia intrinsics because these are the closest we have to how Tegra X1 hardware renders. To stub VOTE on non-Nvidia drivers (including nouveau) this commit simulates a GPU with a warp size of one, returning what is meaningful for the instruction being emulated: * anyThreadNV(value) -> value * allThreadsNV(value) -> value * allThreadsEqualNV(value) -> true ballotARB, also known as "uint64_t(activeThreadsNV())", emits VOTE.ANY Rd, PT, PT; on nouveau's compiler. This doesn't match exactly to Nvidia's code VOTE.ALL Rd, PT, PT; Which is emulated with activeThreadsNV() by this commit. In theory this shouldn't really matter since .ANY, .ALL and .EQ affect the predicates (set to PT on those cases) and not the registers.
