Summary: Allow Wasm programmers and code generators to use short fixed-length vector data and instructions in applications where those are typically used by native code (media encoders/decoders/processors; numeric kernels).
Bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1625130 Standard: https://github.com/WebAssembly/simd, in active development Platform coverage: Initially x64/x86, later arm64, other instruction sets TBD; all operating systems. Preference: javascript.options.wasm_simd (Nightly only). DevTools bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1640593 Other browsers: The Chrome/V8 team is actively driving the development of this feature, origin trial signalled in Chrome 84 ( https://www.chromestatus.com/feature/6533147810332672). web-platform-tests: TBD. A test suite is being developed as part of the spec work and will be included in WPT in due course, in the manner of other Wasm features. Secure contexts: No - all Wasm features are available in all contexts. Is this feature enabled by default in sandboxed iframes? I believe so, in the manner of Wasm in general. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
