2025-07-15Fix language server crash. (#7756)Yong He
* Fix language server crash. * Fix tests. * Fix. * Revert changes.
2025-07-12Add WorkgroupCount function (#7734)davli-nv
Fixes #7733 Copy gl_NumWorkGroups into hlsl.meta.slang as WorkgroupCount function so that it can be used for GLSL and SPIR-V targets without GLSL syntax. Also change WorkgroupSize function to allow use with mesh shading capability. Update pipeline/rasterization/mesh/task-simple.slang to test it in task and mesh stages.

2025-07-11Fix unnecessary Int64 SPIRV capability usage in pointer marshalling (#7717)Copilot
* Initial plan * Fix unnecessary Int64 SPIRV capability usage in pointer marshalling Replace uint64-based pointer marshalling with uint2-based approach to avoid requiring Int64 capability in SPIRV output. This affects both basic type marshalling and resource handle marshalling for pointer types.

2025-07-11Fix segfault with Ptr<T> extension using 'This' type reference (#7719)Yong He
* Fix segfault with Ptr<T> extension using 'This' type reference Set LookupOptions::NoDeref when looking up target type members within extension declarations to prevent automatic pointer dereferencing that was causing breadcrumb handling issues and segfaults. Fixes #7656 Co-authored-by: Yong He <csyonghe@users.noreply.github.com> * Enhance test for ptr-extension-this-type to verify correctness with interpreter - Changed function to return sizeof(This) - sizeof(Ptr<int>) + 1 - Modified test to use interpreter with filecheck to verify result equals 1 - Added main() function that calls the extension method and prints result - Verifies that 'This' correctly refers to Ptr<int> in extension context Co-authored-by: Yong He <csyonghe@users.noreply.github.com> --------- Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> Co-authored-by: Yong He <csyonghe@users.noreply.github.com>
2025-07-11Add DebugGlobalVariable instructions to SPIR-V output (#7686)Jay Kwak
* Add DebugGlobalVariable instructions to SPIR-V output Implements generation of DebugGlobalVariable instructions for global variables like Texture2D and SamplerState in SPIR-V debug information output. Adds debug type support for texture and sampler types using DebugTypeComposite. * Handle two more types for DebugGlobalVariable kIROp_RaytracingAccelerationStructureType and kIROp_SamplerComparisonStateType had to be handled in `emitDebugTypeImpl()` * Fix format * Refactor debug type emission to reduce duplication Use IRSamplerStateTypeBase type check and fallback pattern instead of separate cases for each opcode type. * Fix compiler warning * Simplify `emitDebugTypeImpl()` more
2025-07-11Fix metal segfault by check vectorValue before accessing (#7688)Gangzheng Tong
* Check vectorValue before accessing * Fix metal segfault by using IRElementExtract for general vector handling Address review comments by replacing IRMakeVector-specific code with IRElementExtract to handle any vector instruction type (IRIntCast, etc). This makes the code more robust and fixes cases where float2(1,2) creates IRIntCast instead of IRMakeVector. Co-authored-by: Yong He <csyonghe@users.noreply.github.com> * Fix sign comparison warning in metal legalize Cast originalElementCount->getValue() to UInt to avoid comparison between signed and unsigned integers.

2025-07-09no_diff diagnostics improvement (#7655)kaizhangNV
close #6286. This PR is to improve the diagnostics for no_diff usage. In a differentiable function, any calls to a non-diff function with constant arguments should not require no_diff attribute. This PR adds this extra check at `checkAutoDiffUsages` where it checks the differentiability on IR. In a differentiable method, we will force to use `[NoDiffThis]` attribute if there is access to non-differentiable `This` type. Once this access is detected we will report a warning to bring users attention that this access won't generate any derivative, they have to use `[NoDiffThis]` to suppress that warning. This PR adds this check at type checking stage, because it's the easiest way to find out all the `This` accesses.

2025-07-08Add error for forward references in generic constraints (#7615)sricker-nvidia
* Add error for forward references in generic constraints Change addresses issue #6545. The slang compiler's type checker is unable to support cases where a generic type parameter is referenced as a constraint before it is declared. For example code like: ```` interface IFoo<T : IFloat> { } void bar<Foo : IFoo<T>, T : IFloat>() { } ```` Is not supported, but will currently report a generic error like, "(0): error 99999: Slang compilation aborted due to an exception of class Slang::InternalError: unexpected: generic type constraint during lowering" This change adds a new check for this kind of code and reports an error like, "error 30117: generic constraint for parameter 'Foo' references type parameter 'T' before it is declared" when detected. Basic testing of this error is also added in a new diagnostic test. * Add error for forward refs in generic constiants update 1 * Add error for forward refs in generic constraints update 2 Revised algo in checkForwardReferencesInGenericConstraint to run in O(n) instead of the previous O(n^2) using HashSets. * Add error for forward refs in generic constraints update 3 -Update logic adding referenced decl's in collectReferencedDecls. -Simplified error string logic. * Add error for forward refs in generic constraints update 4 -Declare collectReferencedDecls in slang-check.h such that it can be used as a general utility function. * format code --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>

2025-06-26Fix the invalid SPIRV decoration issue (#7527)kaizhangNV
* Fix the invalid SPIRV decoration issue Close #7508. SPIRV doesn't allow decoration on type with Private or Function storage class. In our lowering logic, if the array type is used by buffer type it will always have stride operand after lowering, so if the array is not used by buffer type, it must be used only by thread_local or group_shared variable, and it will not have stride operand. For this case, we don't need to emit stride decoration for SPIRV.
2025-06-26Correct the scope for DebugLocalVariable (#7516)Lujin Wang
* Correct the scope for DebugLocalVariable All of the DebugLocalVariable instructions have their scope set to DebugCompilationUnit. The scope should instead be set to a DebugFunction, or a DebugLexicalBlock which is recursively inside a DebugFunction. Register the debug info for the function instructions, which helps findDebugScope() to find the right DebugFunction scope for DebugLocalVariable. * Add a test for DebugLocalVariable To check the scope, which should be a DebugFunction.
