Making it easier to work with shaders https://git.yummers.dev/slang.git/atom?h=master 2025-07-16T15:16:06+00:00 2025-07-16T15:16:06+00:00 Mukund Keshava mkeshava@nvidia.com 2025-07-16T15:16:06+00:00 urn:sha1:0bc89f27b08fa7241a7be4f80c2161f25ea3bf78 * Fix 1D texture reads in CUDA target Fixes #7570: 1D surface writes don't work The issue was that the Load function for read-only textures (hlsl.meta.slang lines 3629-3656) only supported 2D and 3D textures for CUDA targets, causing 1D texture reads to fall through to <invalid intrinsic>. This affected the srcTexture[tid.x] read operation in the reproduction case. Changes: - Updated static_assert to include SLANG_TEXTURE_1D support - Added tex1DArrayfetch_int<T> for 1D array texture reads - Added tex1Dfetch_int<T> for regular 1D texture reads 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Mukund Keshava <mkeshavaNV@users.noreply.github.com> * Add 1D texture read support for CUDA target - Add tex1Dfetch_int template specializations for float2, float4, uint, uint2, uint4 - Remove TODO comment about 1D PTX not being supported - Enable 1D texture test in texture-subscript-cuda.slang - Fix assembly code issues in original template specializations 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Mukund Keshava <mkeshavaNV@users.noreply.github.com> * Update slang-cuda-prelude.h * Fix texture3d ptx issue * undo 1D texture changes * Update hlsl.meta.slang * Update hlsl.meta.slang * Update hlsl.meta.slang * Update hlsl.meta.slang * Extend texture-subscript-cuda.slang test with uint and int format variants Add test cases for newly supported texture formats in CUDA: - 2D textures with uint, uint2, uint4 - 2D textures with int, int2, int4 - 3D textures with uint, uint2, uint4 - 3D textures with int, int2, int4 This ensures the texture subscript operations work correctly for all the format variants added in the CUDA texture fixes.
