2024-10-07Add WGSL support for slang-test (#5174)Anders Leino
* Use the assembly description as target when disassembling I believe this is a bugfix. It seems to have worked before because up until the WGSL case, the disassembler has been the same executable as the one producing the binary to be disassembled. * Add Tint as a downstream compiler This closes issue #5104. * Add downstream compiler for Tint. * Tint is wrapped in a shared library, 'slang-tint' available from [1]. * The header file for slang-tint.dll is added in external/slang-tint-headers. * Add some boilerplate for WGSL targets. * Add an entry point test for WGSL. [1] https://github.com/shader-slang/dawn/releases/tag/slang-tint-0 * Add WGSL_SPIRV as supported target for Glslang * Add WebGPU support to slang-test This helps to address issue #5051. * Disable lots of crashing compute tests for 'wgpu' This closes issue #5051. --------- Co-authored-by: Yong He <yonghe@outlook.com>

2024-10-04Add interfaces for retrieving separate linkable downstream binaries (#5128)cheneym2
* Implement separate downstream library interface Create a new com interface to house the methods for precompiling slang modules to target code. Add methods to count dependent modules and scrape them for downstream target binaries such that the downstream target binaries are linkabe outside of slang, e.g. via spirv-link or dxc. Fixes #5147 * Rename to _Experimental Clearly identify this as an interface subject to change.

2024-09-26Implement texture_storage_Xd in WGSL (#5158)Jay Kwak
* Implement texture_storage_Xd in WGSL This commit implements `texture_storage_Xd` in WGSL, which is similar to RWTextureXD in HLSL. It is intresting that `texture_storage_Xd` doesn't take the shader type as its input argument at all. Instead, it takes "texel format" enum value as its first template parameter, which can be found here: https://www.w3.org/TR/WGSL/#storage-texel-formats As an example, `texture_storage_2d<rg32uint, read_write>` expects vec4<u32> as a value type for `Load` and `Store`, where Z-component will be ignored and treated as zero and W-component will be treated always as 1. The type `u32` is inferred from the enum value `rg32uint`. Note that the number of component is always fixed to 4 regardless how many components are actually stored.
2024-09-26Move texture format inference to frontend and add reflection api for it. (#5155)Yong He

2024-09-25WGSL texture support for depth and multisampled (#5152)Jay Kwak

2024-09-25Fixing bug when writing primitives in metal mesh shaders (#5069)Dynamitos
2024-09-25Enable emscripten builds to compile slang.dll to WebAssembly. (#5131)Anders Leino
* Compile fixes for Wasm The issues are all are due to 'long' types being 32 bits on WASM. - class members redeclared errors - << with StringBuilder and unsigned long is ambiguous This helps to address issue #5115. * Use the host executable suffix for generators Since the generators are run at build-time, we should not use CMAKE_EXECUTABLE_SUFFIX, which is the suffix for the target platform. Instead, define CMAKE_HOST_EXECUTABLE_SUFFIX as appropriate, and use that suffix instead. This helps to address issue #5115. * Add support for Wasm as a platform This helps to address issue #5115. * Add emscripten build This closes #5115.
2024-09-24Fix the incorrect use of GLSL textureGather (#5150)Jay Kwak
`$p` was incorrectly removed on the previous commit. This commit brings it back and fixes the problem.
2024-09-23Feature/wgsl intrinsic texture gather (#5141)Jay Kwak
This PR implements the texture gather functions for WGSL. The pattern was very similar to how Metal was implemented. Before copy and paste from the Metal implementation, I had to clean up the Metal implementation to make it more readable and maintainable. Gather functions are available only for 2D and 3D textures. Their `array` and `depth` variants may or may not be supported depending on the target. `static_assert` ensures that Gather functions are available only for 2D and 3D textures. Removed incorrect use of "$p" argument for targeting GLSL.
2024-09-23Implemented Combined-texture for WGSL (#5130)Jay Kwak
* Implemented Combined-texture for WGSL * Remove unnecessary comment * Limit to std430 layout * Fix compiler warning for unused variable --------- Co-authored-by: Yong He <yonghe@outlook.com>

2024-09-20Fix handling of pointer logic in wgsl backend. (#5129)Yong He
2024-09-20WGSL implement texture intrinsics except gather and sampler-less (#5123)Jay Kwak
This commit implements all of the texture intrinsics for WGSL except "Gather" and sampler-less. They will be implemented in a separate PR. A few things to note: - texture sampling functions are available only for the fragment shader stage; not for compute - WGSL doesn't have any functions similar to CalculateLevelOfDetail or CalculateLevelOfDetailUnclamped. - WGSL doesn't have a function overlaoding for textureSample with "clamp" or "status" arguments. - WGSL doesn't support Load operation with offset for texture_multisampled_XX and texture_storage_XX. - WGSL supports only four types of depth textures: 2D, 2D_array, cube and cube_array. - WGSL doesn't support "offset" variants for cube and cube_array.

2024-09-18Lower the priority of looking up the rank of scope (#5065)kaizhangNV
* Lower the priority of looking up the rank of scope In the previous change of #5060, we propose a way to resolve the ambiguous call when considering the scope of a function. But this rule should be considered as a low priority than "specialized candidate", aka. we should consider more "specialized candiate" first. * Count distance between reference site to declaration site Compare the candidate by calculating distance from reference site to declaration site via nearest common prefix in the scope tree. This will involve finding the common parent node of two child nodes and how sum the distance from the common parent to the two child nodes. * Change the priority higher than 'getOverloadRank' * Don't evaluate the scope rank algorithm on generic If the candidate is generic function, the function parameters won't be checked before 'CompareOverloadCandidates', so it will results in that the candidates this function could be invalid. We should not evaluate the distance algorithm in this case, instead we will evaluate later when the candidate is in flavor of Func or Expr since then all the type checks for the function will be done.

2024-09-17Fix WGSL frexp and modf that returns a struct (#5096)Jay Kwak
