2025-09-04Enable CUDA support for additional HLSL intrinsic tests (#8293)Harsh Aggarwal (NVIDIA)
Enable CUDA support for additional HLSL intrinsic tests by implementing missing functionality and fixing compiler bugs affecting CUDA targets. - Fix critical bug in InterlockedCompareStore64 where division used /4 instead of /8 for 64-bit types, causing incorrect memory addressing for all signed int 64_t atomics - Add signed int64_t atomic wrappers (atomicExch, atomicCAS) to CUDA prelu de that properly cast to/from unsigned types as required by CUDA's atomic API - Enable tests: atomic-intrinsics-64bit.slang - Implement CUDA support for QuadAny and QuadAll operations using warp shu ffle primitives (__shfl_sync with quad-level lane masking) - Add CUDA to quad_control capability definition in slang-capabilities.capdef - Add _slang_quadAny/_slang_quadAll helper functions to CUDA prelude - Enable tests: quad-control-comp-functionality.slang, subgroup-quad.slang --------- Co-authored-by: szihs <675653+szihs@users.noreply.github.com>

2025-08-07Initial copy elision pass (#8042)ArielG-NV
Fixes #7574 Changes: * Add an initial (fairly simple) optimization pass which is able to eliminate redundant copies. * Our current existing optimizer passes remove redundant load/store very robustly, this pass will focus on other cases of copy elimination * Primary approach is to make all functions which are `in T` and `T` is trivial to copy into a `__constref T`. We then (depending on scenario) manually insert a variable+load if a pass-by-reference is not possible; otherwise we pass by `constref`. * Added optimizations to eliminate redundant code which causes `constref` to fail to compile --------- Co-authored-by: Harsh Aggarwal <haaggarwal@nvidia.com> Co-authored-by: Claude <noreply@anthropic.com> Co-authored-by: slangbot <ellieh+slangbot@nvidia.com> Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>
2025-08-01Fix 7441: CUDA boolean vector layout to use 1-byte elements (#7862)Harsh Aggarwal (NVIDIA)
* Fix 7441: CUDA boolean vector layout to use 1-byte elements Boolean vectors (bool1, bool2, bool3, bool4) were incorrectly implemented as integer-based types using 4 bytes per element instead of actual 1-byte boolean elements on CUDA targets. Changes: - Update CUDA prelude to define boolean vectors as structs with bool fields instead of typedef aliases to integer vectors - Implement CUDALayoutRulesImpl::GetVectorLayout to use 1-byte alignment for boolean vectors, matching actual CUDA memory layout behavior - Update make_bool functions to populate struct fields correctly This ensures boolean vectors have the same memory layout as bool[4] arrays: - bool1: 1 byte (was 4 bytes) - bool2: 2 bytes (was 8 bytes) - bool3: 3 bytes (was 12 bytes) - bool4: 4 bytes (was 16 bytes) Fixes memory layout mismatch between Slang reflection API and actual CUDA compilation, achieving 75% memory savings for boolean vector usage. * Fix CI issues - Add and update associated functions and operators * Make boolX same as uchar * Use align construct on struct for boolX * Improve Test case for robust alignment checks * Formatting * Disable selected slangpy tests * add metal check which is slightly different than cuda * Test-1 * Test-2 * Test-3 * Test-4 * ReflectionChange * cleanup and update * _slang_select with plain bool is needed for reverse-loop-checkpoint-test

2025-07-16Fix CUDA issues with texture reads and surface writes (#7780)Mukund Keshava
* 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.

2025-04-19Implement 64bit countbits intrinsic (#6433) (#6845)sricker-nvidia
Change modifies the countbits intrinsic to use generics in order to support 64bit countbits on select platforms where this is supported. On platforms where this is not natively supported, we emulate by converting the 64-bit type into a uint2 (metal and spir-v). This should align with the implementation of other uint64_t intrinsics such as abs, min, max and clamp. Added new countbits64 test to verify changes. Updated documentation for 64bit-type-support.html

2024-07-01Error out when constructing tensor views from tensors with 0 stride. (#4516)Sai Praveen Bangaru
This avoids a problem with broadcasted tensors. Our tensor-view platform is designed to allow unrestricted access to tensor memory, while broadcasted tensors were designed for 'read-only' use-cases. Trying to write into a broadcasted tensor needs re-allocation, which Slang is not designed to do. For now, we enforce contiguity on tensors with any 0 strides. In the future, we will introduce a ConstTensorView object to allow such tensors to be used as an input. This patch also propagates name-hint information through structs & arrays of tensors, to allow sensible names for the error messages (before this the error messages were temporary inst numbers, which is nearly impossible to debug)

2024-04-03Implement 8.14-8.19 of OpenGL-GLSL specificationArielG-NV
The following PR implements 8.14-8.19 of the [OpenGL-GLSL specification](https://registry.khronos.org/OpenGL/specs/gl/GLSLangSpec.4.60.pdf). Fully implements all functions and built-in type's, resolves https://github.com/shader-slang/slang/issues/3692 for GLSL & SPRI-V targets. _Notes:_ Testing Tools: * Fragment shaders cannot test computational results. Only OpCodes are checked for proper emitting. Implementation Notes: * SubpassInput requires an unknown image format. * SubpassInput is disjoint from TextureType: __SubpassImpl (.slang) & SubpassInputType (Compiler) to reduce code generation required. * SubpassInput required an additional input layout modifier, input_attachment_index, this was added as a new parameter binding attribute. Since the following qualifiers can overlap with different resources (`layout(input_attachment_index = 0, binding = 0, set = 0)`) input_attachment_index is checked for overlapping resource bindings separately from other qualifiers with `LayoutResourceKind::InputAttachmentIndex`. * `GLSLInputAttachmentIndexLayoutModifier` was added to enforce function parameters only accepting `in` decorated variables. * `in` decorated variables needed to have emitting modified to allow directly emitting the variable into function calls if used as a parameter, normally Slang has a "global variable" shadow as a "global parameter" through a copy. This does not work and is solved using `GlobalVariableShadowingGlobalParameterDecoration` to build a relationship of "global variable" to "global parameter", we then resolve this relationship and replace "global variable" uses later in compile. * `AtomicCounterMemory` memory-constraint requires `OpCapability AtomicStorage`, `AtomicStorage` is invalid for Vulkan targets. glslang outputs for `barrier`, `memoryBarrier`, and `groupMemoryBarrier` `AtomicCounterMemory` as a memory constraint. This compiles as valid SPIR-V for Vulkan since `OpCapability AtomicStorage` is not declared. This behavior of glslang is undefined as per [3.31.Capability of the SPIR-V specification](https://registry.khronos.org/SPIR-V/specs/unified1/SPIRV.html#_capability). We will omit `AtomicCounterMemory` from our barrier calls.
