In this patch NumWorkgroupsFromUniform::Config changed to storage std::optional<sem::BindingPoint>, and if it has no value, NumWorkgroupsFromUniform will choose a free binding group, i.e. binding 0 of the largest used group plus 1 is used if at least one resource is bound, otherwise group 0 binding 0 is used. Tint CLI is also changed to provide a --hlsl-root-constant-binding-point option allowing user to specify the binding point for num_workgroups uniform buffer.

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).
