Without this other Tint transforms may end up calling user code instead of builtins (for example for the min() used in robustness). This commit does the following changes: - Changes ShaderModuleVk to return a CompiledSpirv object instead of just a Spirv Blob so that a remappedEntryPoint can be stored in the cache alongside the SPIR-V. - Inlines the logic and simplifies TransformedConcurrentShaderModuleCache slightly (by introducing a struct instead of std::pair, and adding a conversion method to ModuleAndSpirv). - Adds the Renamer transform to ShaderModuleVk and adapt the code to use the remappedEntryPoint where needed (pipeline creation and post-compilation reflection). - Adds a test where the min() used by the robustness transform is overriden to return a constant 0. - Moves the Renamer transform to be just after the SingleEntryPoint transform in D3D12 and Metal as well so as to make the test pass.

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.
