Implement SV_VulkanSamplePosition (#8236)

2025-08-21T00:30:44+00:00

-Adds semantic SV_VulkanSamplePosition that emits corresponding gl_SamplePosition and SpvBuiltinSamplePosition -Adds gl_SamplePosition property to glsl.meta.slang -Adds SPIRV and GLSL tests for the semantic and property -Plan is to later implement SV_SamplePosition that follows HLSL range of -0.5 to +0.5, and emits GetRenderTargetSamplePosition(SV_SampleIndex) which needs more complicated IR manipulation for HLSL and Metal Fixes #7906 --------- Co-authored-by: ArielG-NV <159081215+ArielG-NV@users.noreply.github.com>

Implement SPV_EXT_fragment_invocation_density (SPV_NV_shading_rate) (#8037)

2025-08-05T17:55:52+00:00

* Implement SPV_EXT_fragment_invocation_density -Adds semantics SV_FragSize and SV_FragInvocationCount and implements them for SPIRV and GLSL using the appropriate target builtins from extensions. -Adds test case checking for expected target builtins from these semantics. -For future work, could implement SV_FragSize using pixel shader input SV_ShadingRate for HLSL, and SV_FragInvocationCount needs research.

* Map SV_VertexID to `gl_VertexIndex - gl_BaseVertex`, provide SV_Vulkan* SV semantics * Fix docs * Regenerate toc * Fix affected pointer-2 test * Add tests --------- Co-authored-by: Yong He

Remove extra User Guide readthedocs TOC entries by turning extra H1 headings into H2 (#6986)

2025-05-06T01:19:06+00:00

readthedocs treats H1 headings as document titles in the sidebar table of contents. This change turns all extra H1 headings into H2 in the "Metal-Specific Functionalities" doc. These extra H1 headings seem to be errors, given that they are inconsistent, and the H2s after them do not belong. For examples, the heading "Resource Types" is H2, but "Array Types" is H1, and "Mesh Shader Support" is H1, but the following "Header Inclusions and Namespace" is not a subtopic of the Mesh Shader Support.
