This reverts commit 5f9996dc9c4c057a6d54d4332d4e4baf2ea904a1. Reason for revert: Issues around locale, will be revisited in a different fashion. Original change's description: > Replace std::stof with std::strtof. > > std::stof can throw std::out_of_range if the input is not actually > representable. We had similar code in Skia which was using stof to > test that a stringized float would round-trip successfully, and it > would throw an exception on some older versions of libc++ for edge- > case inputs like FLT_MIN. > > std::stof is documented as using strtof to do its conversion, so this > shouldn't change your results in practice; it just removes the part > where it could potentially throw for some inputs. > > Tangentially, have you ever seen a case where the scientific-notation > path gets used? According to brucedawson@, nine digits should always > safely round-trip (in 2013, testing gcc and MSVC). See > https://randomascii.wordpress.com/2013/02/07/float-precision-revisited-nine-digit-float-portability/ > > Change-Id: Ie215fb8502dd8c554020c6f73432f91e3d756563 > Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/104500 > Reviewed-by: Dan Sinclair <dsinclair@chromium.org> > Auto-Submit: John Stiles <johnstiles@google.com> > Commit-Queue: Dan Sinclair <dsinclair@chromium.org> > Commit-Queue: John Stiles <johnstiles@google.com> TBR=dsinclair@chromium.org,johnstiles@google.com,noreply+kokoro@google.com,dawn-scoped@luci-project-accounts.iam.gserviceaccount.com,dsinclair@google.com Change-Id: I825f5677f98dea1a13b6423ec18ae3a1e750ce09 No-Presubmit: true No-Tree-Checks: true No-Try: true Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/104502 Auto-Submit: Dan Sinclair <dsinclair@chromium.org> Reviewed-by: Ben Clayton <bclayton@google.com> Commit-Queue: Ben Clayton <bclayton@google.com> Kokoro: Kokoro <noreply+kokoro@google.com> Reviewed-by: John Stiles <johnstiles@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.
