This reverts commit efab8c894e30f2ef78dae59b7ce26d43d6854805. Reason for revert: breaks check_static_initializers check in Chromium https://chromium-review.googlesource.com/c/chromium/src/+/3636809/ due to the line `static Format kUnusedFormat;` in Texture.cpp. Error: file "Texture.cpp" is not expected to have static initializers in binary "chrome" # Static initializers in chrome: # 000101 _Unwind_Resume@plt # 000101 guard variable for std::__1::ios_base::Init::Init()::init_the_streams # 000101 std::__1::DoIOSInit::DoIOSInit() # 000101 std::__1::DoIOSInit::~DoIOSInit() # 000101 std::__1::ios_base::Init::Init()::init_the_streams # 000101 __cxa_atexit@plt [registers a dtor to run at exit] # 000101 __cxa_guard_abort # 000101 __cxa_guard_acquire # 000101 __cxa_guard_release # 000101 __dso_handle # InstrProfilingRuntime.cpp __llvm_profile_initialize # Texture.cpp dawn::native::Format::Format() # Texture.cpp dawn::native::kUnusedFormat # Texture.cpp __dtor__ZN4dawn6nativeL13kUnusedFormatE # Texture.cpp atexit # iostream.cpp: (empty initializer list) # Found 15 static initializers in 4 files.

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).
