Other drivers don't have MSAN instrumentation, so MSAN produces many false positives since it can't track changes to memory from uninstrumented libraries. Also, implement AllocNoThrow for MSAN to return nullptr on large allocations. Local fuzzing found MSAN didn't implement std::nothrow.

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).
