• Split type_ctors_ into array_ctors_ and struct_ctors_. These are the only two type constructors that we need to cache in the Resovler. All other types are cached in the IntrinsicTable. By making these two separate fields, there's no way we can accidentally put other types in there. This is slightly more optimized too, as each map is smaller, and the keys hold less data. • Drop the 'const' on vectors that are std::move()'d. A const object cannot be moved, and this results in a silent copy. Fix the logic of BuiltinCall() and FunctionCall(), as these were happily using the vectors that had been moved. • Extract the messy Texture-Sampling collection logic out into two functions. The rest of the changes are tweaks required to handle abstract numerics and materialization, which will be put up for review shortly. Landing the no-op refactoring now reduces review noise later.

Dawn, a WebGPU implementation
Dawn is an open-source and cross-platform implementation of the work-in-progress WebGPU standard.
More precisely it implements webgpu.h that is a one-to-one mapping with the WebGPU IDL.
Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.
Dawn provides several WebGPU building blocks:
- WebGPU C/C++ headers that applications and other building blocks use.
- The
webgpu.hversion that Dawn implements. - A C++ wrapper for the
webgpu.h.
- The
- A "native" implementation of WebGPU using platforms' GPU APIs:
- D3D12 on Windows 10
- Metal on macOS and iOS
- Vulkan on Windows, Linux, ChromeOS, Android and Fuchsia
- OpenGL as best effort where available
- A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
- Tint is a compiler for the WebGPU Shader Language (WGSL).
