Zhaoming Jiang 4faf3581b8 Tint/builder/spirv: Fix atomicCompareExchangeWeak wrong return
This CL fix the spv code generated for atomicCompareExchangeWeak,
specifically the emulated `exchanged` field of the returned struct.
It should be true if and only if the `old_value`, i.e. the return value
of spv `OpAtomicCompareExchange`, equals to the comparator, rather than
equals to new value.

Fixed: tint:1663

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.h version that Dawn implements.
    • A C++ wrapper for the webgpu.h.
  • 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.
