2024-12-05Fix compiler warning when using slang.h with gcc/clang on Windows (#5766)Kevin Shanahan
The macros SLANG_NO_INLINE, SLANG_FORCE_INLINE, SLANG_BREAKPOINT and SLANG_ALIGN_OF end up getting defined twice when using g++ or clang++ with the slang.h header on Windows. Change the VC specific definitions to depend on SLANG_VC instead of SLANG_MICROSOFT_FAMILY.

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>

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.

2024-11-28wgsl: 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

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.
