These are needed for upcoming separate debug spirv output. Additionally update spirv-headers to fd966619. 2024-12-11T21:28:40+00:00 Jay Kwak 82421531+jkwak-work@users.noreply.github.com 2024-12-11T21:28:40+00:00 urn:sha1:e50aac13e2c161d672b137a62f6d66820d0f9ff1 * 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 2024-09-19T20:02:49+00:00 cheneym2 acheney@nvidia.com 2024-09-19T20:02:49+00:00 urn:sha1:9d40ce4e8921ef468281c91f052dbd443ecf56e2 * Update spirv-headers and spirv-tools versions * Fix compute-derivative regressions with upgraded spirv headers Extension was promoted from NV to KHR while retaining same enums. Fixes #5106 * Prevent DCE on ray trace position fetch Adds dummy usage to the intersection positions fetched from HitTriangleVertexPositions to prevent DCE from removing their usage. Fixes #5105 * Update spirv-tools-generated * More DerivativeGroup*KHR test fixes Add fixes for a missing test intrinsic-derivative-function-in-compute.slang Use the {{NV|KHR}} syntax to tolerate either enum.
