Worked on the shader-slang/slang repository, delivering features and fixes that improved shader language correctness, diagnostics, and SPIR-V output reliability. Focused on enhancing debug information, type clarity, and error reporting for graphics pipelines, the work included implementing robust validation for shader constructs and refining diagnostic coverage to prevent crashes and miscompilations. Leveraged C++, GLSL, and Lua scripting to strengthen compiler internals, introduce unique diagnostic codes, and ensure compatibility with WGSL and other shader standards. The approach emphasized maintainable code, comprehensive regression testing, and cross-team collaboration, resulting in safer code generation and more accurate, developer-friendly debugging across shader toolchains.

Apr 1, 2026Month 2026-04: Delivered a comprehensive Shader language correctness, diagnostics, safety, and compatibility overhaul for slang, with broad improvements across casting semantics, diagnostics, and surface-level compatibility. Implemented robust validation and error reporting for complex shader constructs, enhanced ray tracing payload handling, and introduced stronger mesh/geometry shader validation. Expanded GLSL extension support for TextureCubeArray and ensured proper storage-texture semantics (rgba16float) per WGSL constraints. The iteration also emphasizes regression coverage, with targeted tests and diagnostics to prevent reoccurrence of known crashes and miscompilations.

Jan 1, 2026January 2026: Delivered automatic naming for unnamed struct members in SPIR-V output in the slang repository, adding __memberN naming for unnamed IRStructType members. Improves debugger compatibility and consistency with other compilers, clarifying structured buffer debug information. Fixed issue #9164 in a single commit (812dc34193caca4fba32bd2295d63c00540aaf33); co-authored by Ellie Hermaszewska. Result: smoother debugging, better tooling interoperability, and a clearer SPIR-V debug story for developers.
