Fix reflection JSON writing userAttribs section twice for some cases. (#8210)

2025-08-21T17:00:32+00:00

`emitReflectionVarLayoutJSON` will output the `userAttribs` section twice as it gets output by `emitReflectionModifierInfoJSON` first before being output again by a direct call to `emitUserAttributes`. It seems the answer here is to just remove the extra explicit call to `emitUserAttributes` and rely on the call in `emitReflectionModifierInfoJSON`?

Fix 7441: CUDA boolean vector layout to use 1-byte elements (#7862)

2025-08-01T09:18:53+00:00

* Fix 7441: CUDA boolean vector layout to use 1-byte elements Boolean vectors (bool1, bool2, bool3, bool4) were incorrectly implemented as integer-based types using 4 bytes per element instead of actual 1-byte boolean elements on CUDA targets. Changes: - Update CUDA prelude to define boolean vectors as structs with bool fields instead of typedef aliases to integer vectors - Implement CUDALayoutRulesImpl::GetVectorLayout to use 1-byte alignment for boolean vectors, matching actual CUDA memory layout behavior - Update make_bool functions to populate struct fields correctly This ensures boolean vectors have the same memory layout as bool[4] arrays: - bool1: 1 byte (was 4 bytes) - bool2: 2 bytes (was 8 bytes) - bool3: 3 bytes (was 12 bytes) - bool4: 4 bytes (was 16 bytes) Fixes memory layout mismatch between Slang reflection API and actual CUDA compilation, achieving 75% memory savings for boolean vector usage. * Fix CI issues - Add and update associated functions and operators * Make boolX same as uchar * Use align construct on struct for boolX * Improve Test case for robust alignment checks * Formatting * Disable selected slangpy tests * add metal check which is slightly different than cuda * Test-1 * Test-2 * Test-3 * Test-4 * ReflectionChange * cleanup and update * _slang_select with plain bool is needed for reverse-loop-checkpoint-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
