2024-11-30fetch and extract prebuilt deps lazily (#5707)Ellie Hermaszewska

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>

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.

2024-11-28Sort filenames when generating table of contents (#5659)Ellie Hermaszewska
The order of EnumerateFiles is unspecified
2024-11-28wgsl: Conditionally enable some tests based on 'half' support (#5694)Anders Leino
Require the 'half' rendering feature for WebGPU, so that we can detect when the f16 feature is not available, for the following tests: - tests/language-feature/generics/tuple.slang - tests/language-feature/generics/variadic-0.slang This helps to address issue #5605.
2024-11-27Update workflow YML files for renamed files (#5688)Jay Kwak
Recently we renamed a few files and directories and they should be reflected on the workflow YAML files. - LICENCE is a typo of LICENSE. - We recently created a new "LICENSES/" - CONTRIBUTION.md was renamed to CONTRIBUTING.md Closes #5686
2024-11-26Document the restrictions for vector size (#5673)Jay Kwak
Added a note to clarify that vector types cannot have size bigger than 4.
2024-11-26WGSL: Fix issue where swizzle L-values are generated (#5682)Anders Leino
* wgsl: Do not generate L-value swizzle expressions * Enable tests/language-feature/swizzles/matrix-swizzle-write-*.slang The following tests are enabled - tests/language-feature/swizzles/matrix-swizzle-write-swizzle.slang - tests/language-feature/swizzles/matrix-swizzle-write-array.slang This closes #5603.

* Enable hlsl-intrinsic/byte-address-buffer/byte-address-struct * Set byte address buffer legalization options for WGSL
2024-11-26Enable Link-Time-Code-Generation for Release builds (#5678)Jay Kwak
This commit enables Link Time Code Generation, or LTCG for short, for the release builds. Because "incremental" build is enabled, this ends up using "/LTCG:incremental" rather than the full "/LTCG". It is still expected to more performant than without any "/LTCG" at all. In order to use the full LTCG, we will need to give up the incremental build option for the Release build. We will need to decide if we wants to do it later.

2024-11-22Enable core module embedding by default in CMake. (#5644)Kanashimia
It seems that release workflows were unexpectedly broken when STDLIB was renamed to CORE_MODULE. Changed the option default because I think it just makes more sense. Removed explicit calls to enable it. Fixed docs.

2024-11-21[Docs] Extensions - better wording for c# equivalent (#5636)Ica
slang extensions look pretty same c# extension methods, not partial classes. Partial classes allow extending types to introduce more variables unlike slang extensions. Also c# users that use extension methods much more than partial types, probably. Co-authored-by: Yong He <yonghe@outlook.com>
2024-11-21ci: Update `actions/checkout` to always use v4 (#5634)Bruce Mitchener
CI was using a mix of version 3 and 4. Version 3 results in a warning within the GitHub Actions UI as it was using a version of NodeJS that is deprecated within the GitHub Actions infrastructure.

2024-11-21Enable some rendering tests (#5623)Anders Leino
* render-test: Add copy-source usage for render targets I found that Slang-RHI/WGPU was not able to copy from render targets to staging buffers. This helps to address issue #4943. * Add entries to render API util infos Entries for glsl-cross and glsl-rewrite are added. Without glsl-cross, slang-test fails to select a back-end, and winds up crashing when tests/render/cross-compile-entry-point.slang is enabled tests/render/cross-compile0.hlsl fails similarly without glsl-rewrite. * Enable some rendering tests * Add expected test outputs

2024-11-21Refresh of disabled WGPU tests (#5614)Anders Leino
Some tests are now passing and are enabled. Other tests are still failing, but are given comments categorizing the failures. Tests in the 'Not supported in WGSL' category are also removed from the expected failures list. (Though they are still kept disabled for WebGPU, of course.) This closes #5519.
2024-11-20Change how DeclRef::toText works (#5592)Sai Praveen Bangaru
* Change how DeclRef::toText works We now ignore the decl-ref heirarchy since that only includes nodes with specialization info & simply walk up the tree of decls, while emitting any specializations present in the decl-ref. * Update some tests. Add cases for direct refs to generic params & Lookup decl refs

2024-11-20Clarify stdlib-docgen example (#5619)cheneym2
Add a clarification on the example provided regarding documenting only the first overload. Though the example follows immediately after an existing explanation that only the first overload is present, and that _all_ parameters must be documented there, an extra sentence and the shell of a second overload help drive home the point.
