2025-06-30fix spirv-opt bug (#7565)kaizhangNV
Close #7491. As the PR KhronosGroup/SPIRV-Tools#6198 is already merged, we can switch spirv-tools repo to upstream repo now.
2025-06-30Reset minimum cmake version to 3.22 (#7548)Gangzheng Tong
* Reset minimum cmake version to 3.22 * update slang-rhi
2025-06-27Enable Vulkan Validation Layer in CI (#7543)Gangzheng Tong
* Disable spirv-opt for the tests with debugfunction VVL errors * Enable VVL in CI * Add 2 expected failure tests until we update VVL to 1.4.319 which contains the fix * update slang-rhi * Revert "Disable spirv-opt for the tests with debugfunction VVL errors" This reverts commit 5327460057f533af81ea60a556e43abe805d5816.
2025-06-26Update spirv-tool submodule to include the debug instruct fix (#7541)kaizhangNV
* Update spirv-tool submodule to include the debug instruct fix Update spirv-tool to our forked repo that include the fix of spirv-val bug. It mistakenly relocates the `DebugFunctionDefinition`. The upstream PR is: https://github.com/KhronosGroup/SPIRV-Tools/pull/6198 But it's still pending on review. Issue #7491 will keep track the process, when the upstream PR is merged, we need to restore the repo back to upstream repo.

2025-06-19Enabling optix ci pipeline (#7311)Harsh Aggarwal (NVIDIA)
* Revert "Disable OptiX tests by default. (#1331)" This reverts commit e45f8c1f49855cebe90b6722324ec24146ff5a3d. * Enable optix submodule to build Add support for default entry points in compilation Implemented logic to check for defined entry points in the module when no explicit entry points are provided. If found, these entry points are added to the `specializedEntryPoints` list, with the assumption that no specialization is needed for them at this time. * Disable optix if cuda is not enabled * Add submodule OptixSDK path in search * Distinguish user-explicit vs auto-detected SLANG_ENABLE_OPTIX When SLANG_ENABLE_OPTIX is explicitly set by user and CUDA is not available, show SEND_ERROR to maintain strict validation. When OptiX is auto-detected (e.g., local submodule present) but CUDA unavailable, gracefully disable with STATUS message to allow builds to continue. This addresses review feedback to keep error for explicit requests while handling auto-detection gracefully. * Apply CMake formatting to SLANG_ENABLE_OPTIX validation logic * revert: slang-rhi changes as those are merged independently as in PR # slang-rhi#400
2025-06-19Update slang-rhi (#7457)Simon Kallweit
* update slang-rhi * enable all slang-rhi tests
2025-06-13Fix SLANG_USE_SYSTEM_SPIRV_HEADERS (#7371)Emil Imbert Villumsen
* Use aliased SPIRV-Headers::SPIRV-Headers to also work with an installed SPIRV-Headers SPIRV-Headers standalone is only defined when using sources directly. When consuming an installed SPIRV-Headers via find_package, the full SPIRV-Headers::SPIRV-Headers must be used. The full syntax is supported by both source and installed builds. * Fix SLANG_USE_SYSTEM_SPIRV_HEADERS - Use find_package to bring in SPIRV-Headers cmake targets - Set SPIRV-Headers_SOURCE_DIR as a workaround when including spirv-tools - Query cmake for SLANG_SPIRV_HEADERS_INCLUDE_DIR location, supporting default, SLANG_OVERRIDE_SPIRV_HEADERS_PATH and find_package builds. - Cleanup unnecessary SPIRV_HEADER_DIR (unconditionally overwritten in spirv-tools)

2025-04-17Add Yet Another Source Code Generator (#6844)Theresa Foley
* Add Yet Another Source Code Generator This change introduces an offline source code generation tool, provisionally called `fiddle`. More information about the design of the tool can be found in `tools/slang-fiddle/README.md`. Yes... this is yet another code generator in a project that already has too many. Yes, this could easily be a very obvious instnace of [XKCD 927](https://xkcd.com/927/). This change is part of a larger effort to change how the AST types are being serialized, and the way code generation for them is implemented. Right now, the source code for the new tool is being checked in and the relevant build step is enabled, just to make sure everything is working as intended, but please note that this change does *not* introduce any code in the repository that actually makes use of the new generator. All of the AST-related reflection information that feeds the current serialization system is still being generated using `slang-cpp-extractor`. The design of the new tool is primarily motivated by the new approach to serialization that I'm implementing, and once that new approach lands we should be able to deprecate the `slang-cpp-extractor`. In addition, the new tool should in principle be able to handle many of the kinds of code generation tasks that are currently being implemented with other tools like `slang-generate` (used for the core and glsl libraries). This tool should also be well suited to the task of generating more of the code related to the IR instructions. * format code * Build fixes caught by CI * Fix another warning coming from CI * Another CI-caught fix * Change bare hrows over to more proper abort execptions * format code --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>

2025-01-31Update Slang-RHI and enable any debug layers up-front (#6226)Anders Leino
* Update Slang-RHI and enable any debug layers up-front As [1] shows, creating a D3D12 device and then enabling debug layers causes future device creation to fail. That means enabling debug layers is a process-wide decision that should be done at startup, and not just before creating an individual device. Previously, Slang-RHI enabled debug layers as part of device creation. The new Slang-RHI revision doesn't do that anymore, but instead allows the user to enable debug layers earlier, with a separate API. This change calls the mentioned API before creating any device. This closes #6172. * Compile fixes needed after updating slang-rhi --------- Co-authored-by: Yong He <yonghe@outlook.com>

* Back out "Update SPIRV submodules (#5815)" This backs out commit e50aac13e2c161d672b137a62f6d66820d0f9ff1. * Use upstream spirv-tools * Fix bump-glslang.sh for newer versions of spirv-tools * Use upstream glslang * Add --do-fetch option to bump glslang * Bump glslang and friends Supersedes https://github.com/shader-slang/slang/pull/5815 * Regenerate glslang and spirv-tools outputs * Fixes to slang-glslang * Correct spirv intrinsic for OpImageSampleFootprintNV Note that this currently fails validation with the following error: ``` error: line 145: Result <id> from OpSampledImage instruction must not appear as operand for OpImageSampleFootprintNV, since it is not specified as taking an OpTypeSampledImage. Found result <id> '55[%sampledImage]' as an operand of <id> '56[%resultVal]'. %sampledImage = OpSampledImage %54 %51 %40 ``` This seems to be in error as the spec for *SPV_NV_shader_image_footprint* states that "Sampled Image must be an object whose type is OpTypeSampledImage" https://refined-github-html-preview.kidonng.workers.dev/KhronosGroup/SPIRV-Registry/raw/refs/heads/main/extensions/NV/SPV_NV_shader_image_footprint.html glslang also seems to fail with the same validation error * Fix spv storage class test
2024-12-11Update SPIRV submodules (#5815)Jay Kwak
* Update SPIRV submodules With the latest SPIR-V submodules, one of tests started failing: tests/gpu-feature/texture/query/footprint/nv-shader-texture-footprint.slang [ForceInline] is added to GLSL texture functions in order to inline %true and %false. Without it, the value was indirectly passed down via a function parameter, which broke the existing test. Also the test is modified to use -DAG, because the order unpredictably changed for Grad variants due to additional [ForceInline] marks for Gradient functions. A new validation check in SPIRV-Tools was causing a validation error: ``` error: line 324: [VUID-StandaloneSpirv-OpTypeImage-06924] Cannot store to OpTypeImage, OpTypeSampler, OpTypeSampledImage, or OpTypeAccelerationStructureKHR objects OpStore %17 %242 ``` It appears that this is a bug on SPIRV-Tools. A proper fix is proposed to Khronos/SPIRV-Tools: https://github.com/KhronosGroup/SPIRV-Tools/pull/5914 But this commit uses `shader-slang/SPIRV-Tools/fix_for_OpImageSampleFootprintNV` with a custom fix as a temporary solution: https://github.com/shader-slang/SPIRV-Tools/tree/fix_for_OpImageSampleFootprintNV
2024-11-28Update Slang-RHI/slang (#5701)Anders Leino
* Update Slang-RHI/slang This brings in new fixes for WebGPU. In particular, the "use_dxc" toggle is now used, which should enable these tests to run on WebGPU, if f16 is otherwise supported: - `tests/language-feature/generics/variadic-0.slang` - `tests/language-feature/generics/tuple.slang` This closes #5605. * Disable tests/autodiff/float-cast.slang for wgpu This test was previously not running for WebGPU because it required the 'half' render feature, and Slang-RHI was previously not reporting it. With the Slang-RHI update, the test now runs on WebGPU. It now fails because the test is using 'double' which is just not supported on WebGPU. Thus this commit disables the test.
