Explainer https://github.com/WebAssembly/extended-const/blob/main/proposals/extended-const/Overview.md Specification https://github.com/WebAssembly/extended-const Summary We implement the WebAssembly extended-const proposal according to https://github.com/WebAssembly/extended-const. Specifically, we add i32.add, i32.sub, i32.mul, i64.add, i64.sub and i64.mul to the list of constant instructions. Blink component Blink>JavaScript>WebAssembly <https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink%3EJavaScript%3EWebAssembly> TAG review Not needed in our view, as this is a very small change to existing functionality. Risks Interoperability and Compatibility N/A. The WebAssembly spec <https://github.com/WebAssembly/proposals#phase-4---standardize-the-feature-wg> reached Phase 4, therefore engines will implement it. Debuggability Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)? Yes Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md> ? WebAssembly Spec Tests: https://github.com/WebAssembly/extended-const/tree/main/test Flag name Experimental WebAssembly Requires code in //chrome? False Estimated milestones M113 behind a flag, M114 as default Tracking bug https://bugs.chromium.org/p/v8/issues/detail?id=12089 Estimated milestones DevTrial on desktop 113 DevTrial on Android 113 Anticipated spec changes Open questions about a feature may be a source of future web compat or interop issues. Please list open issues (e.g. links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (e.g., changing to naming or structure of the API in a non-backward-compatible way).
