* Update SPIRV-{Tools,Headers} (#8415)Jay Kwak2025-09-10
| | | | | | | | | This updates SPIRV submodules. Unfortunately we cannot use the latest because one of PRs in SPIRV-Tools causes VVL errors on our slang-tests. The issue is tracked in - https://github.com/KhronosGroup/SPIRV-Tools/issues/6316 - https://github.com/shader-slang/slang/issues/8414 This PR also updates/simplifies the document of updating SPIRV process.
* Update spirv-tools and spirv-headers (#7500)jarcherNV2025-06-21

* Update spirv-tools to point at 7dda3c01f (#7352)jarcherNV2025-06-05
| | | | | Update spirv-tools to take the DebugBuildIdentifier changes. These are needed for upcoming separate debug spirv output. Additionally update spirv-headers to fd966619.

* Bump spirv-header/tools/glslang (#5834)Ellie Hermaszewska2024-12-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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
* Update SPIRV submodules (#5815)Jay Kwak2024-12-11
| | | | | | | | | | | | | | | | | | | | | | | | * 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
* Update spirv-tools version (#5089)cheneym22024-09-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Update spirv-headers and spirv-tools versions * Fix compute-derivative regressions with upgraded spirv headers Extension was promoted from NV to KHR while retaining same enums. Fixes #5106 * Prevent DCE on ray trace position fetch Adds dummy usage to the intersection positions fetched from HitTriangleVertexPositions to prevent DCE from removing their usage. Fixes #5105 * Update spirv-tools-generated * More DerivativeGroup*KHR test fixes Add fixes for a missing test intrinsic-derivative-function-in-compute.slang Use the {{NV|KHR}} syntax to tolerate either enum. Fixes #5106 * Squash tabs in closesthit test * HACK test CI * Avoid multiple IncomingRayPayloadKHR storage params * Revert "HACK test CI" This reverts commit c2556ea2baef0bd48e4c86f90cf17dfab80015c1. * Avoid multiple IncomingRayPayloadKHR storage params in anyhit

| | | | | | | | | | | | | | | | | * Split render-d3d12 into numerous smaller files to make the code easier to parse * Added all new D3D12 files created from splitting render-d3d12 * Fixed several uses of attachment still floating around; Changed resource-d3d12 and descriptor-heap-d3d12 to match naming conventions of new d3d12 implementation header files * Readded files with name changes because changing them from inside VS apparently results in them being treated as new files * Merged in externals changes from master * Small cleanup changes * Rerun CI Co-authored-by: Theresa Foley <10618364+tangent-vector@users.noreply.github.com>

Updated documentation. * Update spirv-headers/tools. Revert slang-binaries. * Remove hack around spir-v optimization as no longer needed. disable nv-ray-tracing-motion-blur.slang

* Upgrade glslang to 11.5.0 (#1910)jsmall-nvidia2021-07-16
| | | | | | | * #include an absolute path didn't work - because paths were taken to always be relative. * Upgrade glslang to 11.5.0 * Remove no longer needed section from glslang-generated/README.md
* Update glslang to 11.1.0 (#1662)Tim Foley2021-01-20
| | | | | | | | | * Update glslang to 11.1.0 This change pulls new versions of glslang, spirv-headers, and spirv-tools as submodules, and makes the necessary changes to other files in the repository to get it all building (at least on Windows). This change also enables building of glslang from source by default, so that we can easily generate new binaries for inclusion in the `slang-binaries` repository. * fixup: missing file
* Upgrade to Glslang 11.0.0 (#1466)jsmall-nvidia2020-07-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Fix premake5.lua so it uses the new path needed for OpenCLDebugInfo100.h * Keep including the includes directory. * Added the spirv-tools-generated files. * We don't need to include the spirv/unified1 path because the files needed are actually in the spirv-tools-generated folder. * Put the build_info.h glslang generated files in external/glslang-generated. Alter premake5.lua to pick up that header. * First pass at documenting how to build glslang and spirv-tools. * Improved glsl/spir-v tools README.md * Added revision.h * Change how gResources is calculated. Update about revision.h * Update docs a little. * Split out spirv-tools into a separate project for building glslang. This was not necessary on linux, but *is* necessary on windows, because there is a file disassemble.cpp in spirv-tools and in glslang, and this leads to VS choosing only one. With the separate library, the problem is resolved. * Fix direct-spirv-emit output. * Update to latest version of spirv headers and spirv-tools. * Upgrade submodule version of glslang in external. * Add fPIC to build options of slang-spirv-tools * Upgrade slang-binaries to have new glslang. * Fix issues with Windows slang-glslang binaries, via update of slang-binaries used. * Small improvements to glslang building process documentation.
