* Add error for forward references in generic constraints (#7615)sricker-nvidia2025-07-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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>

* Fix diagnostics not appearing when semantic tokens are disabled (#7477) (#7532)Harsh Aggarwal (NVIDIA)2025-07-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Fix diagnostics not appearing when semantic tokens are disabled (#7477) Previously, the language server only triggered module loading and compilation through semantic token requests. When semantic tokens were disabled, didOpenTextDocument and didChangeTextDocument would only update the workspace without compiling modules, meaning no diagnostics were generated. This change: - Adds module loading to didOpenTextDocument for .slang/.hlsl files - Adds module loading to didChangeTextDocument for .slang/.hlsl files - Triggers diagnostic updates via resetDiagnosticUpdateTime for Slang files - Ensures diagnostics appear immediately when opening/editing files - Maintains backward compatibility with existing LSP features Additionally fixes JSON serialization to properly handle NullResponse types by serializing them as JSON null instead of empty objects, improving LSP protocol compliance. Now diagnostics work correctly regardless of semantic token settings. * Revert: Remove unrelated change - will pick up in seprate PR * Fix module state corruption when checkAllTranslationUnits throws Add try/catch in Linkage::loadParsedModule to properly clean up module maps when checkAllTranslationUnits() fails with an exception. This prevents incorrect state in WorkspaceVersion::getOrLoadModule where failed modules remained in the loaded modules map, causing subsequent calls to return stale/invalid module references. * Update to address review comments * update: remove explicit checking for .slang and .hlsl

* Remove some cruft/complexity from IR serialization (#7483)Theresa Foley2025-07-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Remove some cruft/complexity from IR serialization This is a very simple cleanup to unnecessary code paths and remove some flexibility that isn't actually needed, to hopefully simplify the task of more completely overhauling the approach to IR serialization in a later change. The concrete feature that gets removed here is a debug-only feature (which thus shouldn't be affecting any users of Slang) that was added long ago in the life of the compiler as we were working to truly separate the front- and back-ends. At the time there was a lot of code in the compiler back-end that still made use of AST-level data structures, and thus got in the way of our goal to support separate compilation and linking (such that final code generation can only depend on the IR, and not the AST). The option was used to cause the Slang IR to be serialized out and then read back in as part of compilation, to try and enforce that only the wanted constructs could pass through that bottleneck. The idea was only ever half implemented, however, because it made use of a secondary implementation path in IR serialization that supported serializing the "raw" source locations (which are heavily dependent on AST-level information, even down to the number of bytes in source files). This change removes the feature entirely, since it is no longer useful for its intended purpose, and its presence causes there to be entire second code path for source locations in IR serialization that would need to have test coverage if we wanted to be sure it kept working. In addition, our pre-existing infrastructure for module serialization had various options that have either stopped being useful, or were not really useful at the time they were introduced. For example: there are no places in the code today where we attempt to serialize out a module without including both the serialized AST and IR. If that was a feature that we ever supported, the relevant code got removed at some preceding point without breaking any of our tests or (seemingly) upsetting users. Similarly, the options being passed into writing of a serialized module included both a flag to control whether source locations should be serialized *and* a pointer to the `SourceManager` to use in that case... but it was only ever meaningful to set both, or neither. The option has been changed to just be the `SourceManager` pointer, and the name has been updated to reflect its very narrow intended use case. * format code * fixup * regenerate command line reference --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com> Co-authored-by: Yong He <yonghe@outlook.com>
* Remove redundant [payload] attribute (Fix #7528) (#7555)Harsh Aggarwal (NVIDIA)2025-06-30
| | | | | | | | | | | | Removes the PayloadAttribute class and related infrastructure that was made redundant by PR #6595, which added ray payload access qualifiers (PAQs) per the DXR spec. The new [raypayload] attribute with access qualifiers provides the same functionality. Changes: - Remove PayloadAttribute class from slang-ast-modifier.h - Remove [payload] attribute syntax from core.meta.slang - Remove PayloadDecoration IR instruction and related processing - Remove HLSL emission of [payload] attribute - Remove IR lowering support for old PayloadAttribute The new [raypayload] attribute with PAQ support remains unchanged.

| | | | | | | | | | | | | | * 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.

| | | | | | | | | | | | | | | | * 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.
