When enabling the SPIR-V reader or SPIR-V writer we were suppressing -Wnewline-eof, -Wold-style-cast, -Wsign-conversion, and -Wweak-vtables for the `libtint` cmake target and anything that depended on that target. Because we'd build all readers/ writers by default this caused us to never hit those warnings. A recent change to the cmake build sets the Tint backend based on the Dawn backend. So, there is a much higher chance of not building the SPIR-V support if you're on a Mac or Windows machine. This CL removes the suppression of the warnings, adds specific pragmas into the SPIR-V reader code which imports the SPIRV-Tools headers and fixes up the warnings which were then firing due to checking for the new warnings.

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
.
- 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).
