Enable CUDA support for additional HLSL intrinsic tests (#8293)

2025-09-04T05:28:02+00:00

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>

Error if super-type capabilities are a super-set of sub-type (#7452)

2025-08-08T20:19:25+00:00

Fixes: #7410 Changes: 1. super-type capabilities must be a super-set of sub-type capabilities (and support the same shader stages/targets) * InheritanceDecl visits super-type to inherit it's capabilities; validate InheritanceDecl capabilities against sub-type * visit all container decl's with a default case * clean up functionDeclBase visitor * Simplify `diagnoseUndeclaredCapability` by moving logic into capability checking (more correct*) 3. added changed behavior to documentation 4. fixed some incorrect capabilities 5. **we do not** diagnose capability errors on interface requirement-to-implementation if both lack explicit capability requirements. This change is to work around a slangpy regression (test case for the failing situation is in `tests\language-feature\capability\capability-interface-extension-1.slang`), Note: maybe for slang-2026 we don't do this? 6. requirement & implementation must support the same shader stage/target. This was changed because otherwise we can have cases where `X` inherits from `Y`, but `Y` is only expected to be used in `glsl` whilst `X` is expected to be used in `hlsl | glsl` 7. removed `tests/language-feature/capability/capabilitySimplification3.slang` because it tests nothing special (redundant) Note: not using rebase due to separate branches depending on this PR --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>

Fix broken -emit-spirv-via-glsl test option (#7091)

2025-05-16T00:01:08+00:00

Fixes issue #6898 The -emit-spirv-via-glsl slang-test option has been broken for some amount of time. Tests that were using it were operating as if using -emit-spirv-directly, leading to many duplicated tests. After fixing the test option, there were an number of errors that appeared as a result. This change fixes the broken test option and the resulting test errors. Some of the test errors revealed some legitimate issues, such as: -The GLSL bitCount instrinsic only supports 32-bit integers and requires emulation for other bit widths. -Emitting GLSL 8-bit and 16-bit glsl integer types did not emit the proper extension requirements -Emitting GLSL and casting for 16-bit integers was missing a closing parenthesis. -Missing profile for GL_EXT_shader_explicit_arithmetic_types -Missing toType cases for UInt8/Int8 for the kIROp_BitCast case in tryEmitInstExprImpl.
