Allow entry points with missing numthreads on CPU targets (#8678)

2025-10-10T23:01:51+00:00

Several tests have compute entry points without a `[numthreads(x,y,z)]` decoration. Currently, none of these tests run on the CPU target, as they crash the compiler. I took a look at the SPIR-V emitter, which falls back to a workgroup size of (1,1,1): https://github.com/shader-slang/slang/blob/1e0908bd7107dfbdac912b693c3ab9bd6e1dc8b3/source/slang/slang-ir-spirv-legalize.cpp#L1635-L1643 To match this behaviour, this PR implements a fallback solution that makes `emitCalcGroupExtents()` emit (1,1,1). This PR is both a question and a suggestion; I'm not sure the approach here is at all reasonable. Personally, I'd just like to explicitly add `[numthreads(1,1,1)]` to all such tests, but I don't know if it's actually legal and supported to not have a `numthreads`. So the implementation here is a bit conservative. I ran across these when I went through tests for the upcoming LLVM target. These were the final blockers to get all autodiff and language-features tests passing (not counting the ones using things like wave intrinsics and barriers etc.)

Use symbol alias instead of wrapper synthesis to implement link-time types. (#8603)

2025-10-07T00:21:37+00:00

This change achieves link-time type resolution with a different mechanism. For `extern struct Foo : IFoo = FooImpl;`, instead of synthesizing a wrapper type `Foo` that has a `FooImpl inner` field and dispatches all interface method calls to `inner.method()`, this PR completely removes this synthesis step, and instead just lower such `extern`/`export` types as `IRSymbolAlias` instructions that is just a reference to the type being wrapped. Then we extend the linker logic to clone the referenced symbol instead of the SymbolAlias insts itself during linking. By doing so, we greatly simply the logic need to support link-time types, and achieves higher robustness by not having to deal with many AST synthesis scenarios. Closes #8554. --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>

Fix public unscoped enum constants not visible across module boundaries (#7864)

2025-07-22T22:53:19+00:00

* Initial plan * Fix public unscoped enum constants visibility across module boundaries Add visibility modifier copying in CompleteDecl for unscoped enum cases. When synthesizing static const declarations for unscoped enum cases, copy the visibility modifiers from the original enum declaration to ensure they have the same visibility scope across module boundaries. Co-authored-by: csyonghe <2652293+csyonghe@users.noreply.github.com> * Create new visibility modifier instances instead of sharing existing ones Address reviewer feedback to avoid sharing modifier instances between declarations since modifiers form a linked list. Now creates new instances of the appropriate visibility modifier type (Public, Private, or Internal) instead of reusing the existing instance.

Fix intermittent debug failures with Debug build (#7369)

2025-06-12T05:33:16+00:00

This PR replaces enable/disable style C function calls with C++ RAII style code. In debug build, when an assertion failed in between enable and disable functions, an exception is thrown and the disable function is not called. RAII style code is safer for an exception
