CMake-only fork of https://dawn.googlesource.com/dawn with cleaned, vendored dependencies
8525ff29da
This change overhauls the Robustness transform to support three modes,
per address space:
* ignore - Disable robustness checks for the address space
* clamp - Clamp indices / texture args to ensure they're in
bounds. This was the old behavior, and continues to
be the default.
* predicate - Condition all indexing / textureLoad / textureStore /
atomic* operations on the bounds check. If any
dependent value is out of bounds, then the operation
is skipped.
This change also fixes multiple expression evaluation of the texture
builtin 'level' argument.

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.
