tint: add syntax sugar for dereferencing pointers Adds support to Tint for syntax sugar for dereferencing pointers for member or index access as per: https://github.com/gpuweb/gpuweb/pull/4311 - Resolver: when the lhs of a accessor expression is a pointer, it is now resolved to a sem::Reference. - Added "pointer_composite_access" feature as experimental, hooked up validation in Resolver, and added tests. - Added resolver tests for the new syntax to resolver/ptr_ref_test.cc. - Fixed multiple transforms to deal with the fact that the lhs of accessor expressions can now be pointers, including: Robustness, Renamer, Std140, and SimplifyPointers. - In transforms that rely on other transforms, such as SimplifyPointers, to remove/inline pointers, I added asserts that the type is not a pointer. - Added unit tests for transforms that use pointer-dot/index for accessor expressions. - Fixed uniformity analysis code so that ProcessLValueExpression correctly deals with accessor expressions where the object is a pointer, in the same way we do for UnaryOp::kIndirection, including partial pointer checks. Added many tests for these new cases. - Fixed ProgramToIR so that EmitAccess handles the new syntax. Added multiple tests. - Added end2end tests under test/tint/ptr_sugar For Googlers, see my work log at go/add-syntax-sugar-for-dereferencing-composites for more details.

Dawn is an open-source and cross-platform implementation of the 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:
