This patch introduces two new macros to replace DAWN_SKIP_TEST_IF(): 1. DAWN_SUPPRESSED_TEST_IF(): for the tests failing on a specific HW / backend / OS combination 2. DAWN_TEST_UNSUPPORTED_IF(): for the tests which require an extension or a toggle to be present /not present or some WIP features. This patch also adds a command line parameter "--run-suppressed-tests" to disable the macro DAWN_SUPPRESSED_TEST_IF(), so that we can test any tests that are related to any specific HW / backend / OS combinations without changing the source code and re-building dawn_end2end_tests. This patch also replaces DAWN_SKIP_TEST_IF() with DAWN_SUPPRESSED_TEST_IF() or DAWN_TEST_UNSUPPORTED_IF() in QueryTests.cpp and ShaderFloat16Tests.cpp to test the functionality of these two new macros. DAWN_SKIP_TEST_IF() will be completely replaced by DAWN_SUPPRESSED_TEST_IF() or DAWN_TEST_UNSUPPORTED_IF() in the next patch.

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
