These fix the tests so that the entire of Dawn can now be built with VS2019. Some details: Multiples of "error C3493: 'X' cannot be implicitly captured because no default capture mode has been specified" in BufferTests.cpp. This appears to be a bug in VS whereby the constexprs need capturing; the workaround, rather than explicitly name them and change the function signature, is to make the vars also static. In DepthStencilSamplingTests.cpp we get "warning C4310: cast truncates constant value" for uint8_t(256). Rather than try to silence the warning the test was removed, since the cast will *always* result in zero, which is also the first in the test values. To successfully build two further third-party dependencies also require updating: https://dawn-review.googlesource.com/c/tint/+/37700 https://chromium-review.googlesource.com/c/angle/angle/+/2624888 Note: whilst this now builds the entire of Dawn with VS not yet all of the build arguments are supported. Yet to investigate is turning on optimisations (with is_official_build=true) which attempts to combine "/INCREMENTAL" with "/OPT:REF" and fails (to be addressed next).

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
