Add FindModifier for Declarations (#8308)

2025-09-10T22:55:00+00:00

Add `findModifier` for `DeclReflection` so pattern like `extern struct foo;` can be properly reflected. Closes #8009

Add check for backtrace availability (#8329)

2025-09-06T02:38:08+00:00

The header execinfo.h and the related backtrace functionality is not available on all linux platforms. In particular it's missing on musl linux and on Android before API version 33. This causes compilation errors on those platforms. With this change, we first check if backtrace functionality is available by checking if we are using glibc or a compatible Android version. Tested on manylinux_2_28 with glibc 2.28 and musllinux_1_2 with musl 1.2, has not been tested on Android. Co-authored-by: Yong He

Introduce CDataLayout & -fvk-use-c-layout (#8136)

2025-08-21T05:47:18+00:00

Closes #8112. ~~The issue asks for a "C layout", but in this PR I use the term "CPU layout" because this naming was pre-existing in the codebase as `kCPULayoutRulesImpl_`. The primary purpose of this layout is to match CPU-side struct definitions with the shader side. I'm open to better naming suggestions, though.~~ Edit: switched back to using `CDataLayout` & `-fvk-use-c-layout`, as the CPU target depends on the object layout rules of existing CPU layout rules, but they're incompatible with actual shaders. So a new `kCLayoutRulesImpl_` was needed anyway. --------- Co-authored-by: Ellie Hermaszewska

msvc style bitfield packing (#7963)

2025-07-31T07:23:13+00:00

Closes https://github.com/shader-slang/slang/issues/3646 New tests rather than just adding another TEST line to existing tests so that we get the msvc- prefix in the output of slang-test

Fix mesh shader reflection JSON output (#7868)

2025-07-25T20:16:12+00:00

* Fix mesh shader reflection JSON output Fixes issue #7736 where mesh shaders were showing stage "UNKNOWN" and missing type information in reflection JSON output. Changes: - Add missing SLANG_STAGE_MESH and SLANG_STAGE_AMPLIFICATION cases to shader stage switch statements in emitReflectionVarBindingInfoJSON and emitReflectionEntryPointJSON - Add missing MeshOutput to TypeReflection::Kind enum in slang.h - Add missing type kind cases (OutputStream, MeshOutput, Specialized, None) to emitReflectionTypeInfoJSON Testing: - Simple mesh shader now correctly shows "stage": "mesh" instead of "UNKNOWN" - Complex mesh shader with parameters shows proper stage and input type information - Output parameters show "kind": "None" instead of crashing with assertion 🤖 Generated with [Claude Code](https://claude.ai/code) Co-authored-by: pdeayton-nv * Remove test files from mesh shader reflection fix As requested, removed test files since there is no testing infrastructure for reflection JSON output. Focus is now only on the core mesh and amplification shader reflection fixes. Co-authored-by: pdeayton-nv * Address review comments: move MeshOutput enum to end and restore assert - Move MeshOutput enum member to end of TypeReflection::Kind enum for backward compatibility - Replace fprintf with SLANG_ASSERT for unhandled type kinds Co-authored-by: pdeayton-nv --------- Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> Co-authored-by: pdeayton-nv Co-authored-by: Yong He
