We already compute the "first" and "last" basic block that uses a value, so we could know when to hoist a value into a var declaration. You have to do this sometimes to make sure all uses are in scope of the declaration. Until now we tracked Phis with an entirely different mechanism. But there are cases which broke down. That's what happens in crbug.com/tint/1649. Additionally, GraphicsFuzz cases generarte similar weirdness. Also, be more careful about ensuring that the assignments generated to feed phis behave as if they occur in parallel. Within a single batch of such assignments, generate and use intermediate let-declarations for phis that that batch will overwrite. Also, unwrap-references when rectifying the signedness of binary operators. Skip tests that fail due to crbug.comt/tint/98: test/tint/bug/tint/749.spvasm.* Fixed: tint:1649 Change-Id: I7314c351b74a10bfa9a18011f3d80a520568011c Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/101220 Auto-Submit: David Neto <dneto@google.com> Commit-Queue: David Neto <dneto@google.com> Reviewed-by: Ben Clayton <bclayton@google.com> Kokoro: Kokoro <noreply+kokoro@google.com> |

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.
