This patch: 1. Add the `f16` WGSL extension. 2. Add `f16` as keyword, and remove it from reserved word list. 3. Add ast::f16 and sem::f16, and implement validation that using `f16` type must be with `f16` extension enabled. 4. Add `Number<NumberKindF16>` for f16 literal and constant, and add `ast::FloatLiteralExpression::Suffix::kH`. 5. Add placeholder in all writer which report error when try to emit f16 type.

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).
