• Add `cts validate` command used to check for expectation collisions. Can be used as a presubmit check. This is more tightly checked than the previous logic, as this works on just the expectations, instead of results. • Fix an issue where the test result reduction could introduce collisions with 'Skip' expectations. To fix this, the update process first adds 'consumed' results for the skipped tests, preventing test tree reduction for that part of the tree. • Fix a bug in the generation of 'New failures' and 'New flakes' which produced more expectations than was necessary. The issue here was that the tree roots could contain overlaps, and roots could be processed before sub-trees, resulting in inefficient expectations. • Fix collisions in the expectations file, and update with results from the most recent roll.

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, Metal, Vulkan and OpenGL. See per API support for more details.
- 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) that can be used in standalone to convert shaders from and to WGSL.
