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. Closes #5580 Closes #5581 Closes #5587

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>

2024-11-21Enable 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

2024-11-13Correct include dir for libslang (#5539)Ellie Hermaszewska
This stops adding the repo root to the include path for anything linking with slang. This enabled a bunch of convenient includes, but might lead to confusing behavior for anyone including slang. Not to mention differences including it from an install vs source. Co-authored-by: Yong He <yonghe@outlook.com>
