2024-12-12WGSL: Fix issue where global calls are generated (#5768)Anders Leino
* Split out SPIR-V -specific legalization of global functions This is a refactoring and should not affect generated code. * Move global inst inlining code into separate function This is a refactoring and should not affect generated code. * Take SPIR-V -specific parts out of GlobalInstInliningContext This is a refactoring and should not affect generated code. * Move 'inlineGlobalValues' to generic inlining context This is a refactoring and should not affect generated code. * Move 'setInsertBeforeOutsideASM' to generic inlining context This is a refactoring and should not affect generated code. * Move generic inlining context into own file This is a refactoring and should not affect generated code. * Run global inlining for WGSL as well * Make the 'getOutsideASM' function generic as well * Enable language-feature/constants/static-const-in-generic-interface.slang for WebGPU * Clarify when it's safe to remove and deallocate an IRInst * Remove globals if they're left unused after inlining This closes #5607. * Handle IRGlobalValueRef in C-like emitter * format code --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>

2024-12-12Bump spirv-header/tools/glslang (#5834)Ellie Hermaszewska
* 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

2024-12-03Core lib Metal math function fixes (#5738)cheneym2
In order to emit fast target implementations of some Metal-based functions (fmin(), fmax(), fmin3(), fmax3(), fmedian3()) on all targets, remove some specification regarding the handling of NaNs, and also remove the enforcement of the specification. These functions are now documented to be basically undefined now in the presence of NaN input, to make the common "is a number" case fast. Also, clarify that powr() is undefined when given a non-positive base input value, allowing us to remove an additional abs() operation that was unnecessarily coercing results to be predictable on non-Metal targets.

2024-11-29Emit OpExecutionMode SpacingEqual for Domain stage (#5696)Jay Kwak
Domain stage should emit one more `OpExecutionMode` with `SpacingEqual`, similary to how Hull stage does. Currently Hull stage emits four OpExecutionMode as following: OpExecutionMode %hullMain SpacingEqual OpExecutionMode %hullMain OutputVertices 4 OpExecutionMode %hullMain VertexOrderCw OpExecutionMode %hullMain Quads And Domain stage emits only one OpExecutionMode: OpExecutionMode %domainMain Quads This commit adds the following instruction for Domain stage: OpExecutionMode %domainMain SpacingEqual It is because the Vulkan Validation Layer prints error when the Domain shader didn't have `OpeExecutionMode SpacingEqual`. `SpacingEqual` corresponds to an attribute, `[partitioning("integer")]`, given to the Hull stage. Although Domain stage is not marked with same attribute, it is assumed to use the same value used for matching Hull Stage. The error message from VVL is following: ``` vkCreateShadersEXT(): pCreateInfos[2].stage is VK_SHADER_STAGE_TESSELLATION_EVALUATION_BIT, but spacing is not specified. The Vulkan spec states: If codeType is VK_SHADER_CODE_TYPE_SPIRV_EXT, and stage is VK_SHADER_STAGE_TESSELLATION_EVALUATION_BIT, pCode must contain an OpExecutionMode instruction specifying the spacing of segments on the edges of tessellated primitives (https://vulkan.lunarg.com/doc/view/1.3.283.0/windows/1.3-extensions/vkspec.html#VUID-VkShaderCreateInfoEXT-codeType-08874) ``` Co-authored-by: Ellie Hermaszewska <ellieh@nvidia.com>
