Explainer https://github.com/aheejin/exception-handling Specification https://github.com/WebAssembly/exception-handling Summary This feature is adding exception support to WebAssembly. Exception handling allows code to break control flow when an exception is thrown. The exception can be any exception known by the WebAssembly module, or it may be an unknown exception that was thrown by a called imported function.

This feature is one of the last bits missing to port legacy c++ apps to the web. Code that uses WebAssembly Exception Handling can be generated by Emscripten <https://emscripten.org/docs/porting/exceptions.html> and has been used successfully in the origin trial. Debuggability Supported using DevTools Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/master/docs/testing/web_platform_tests.md> ? Yes, tests are provided by the spec, see https://github.com/WebAssembly/exception-handling/tree/master/test. Flag name WebAssembly Exception handling can be enabled and disabled by the V8 Flag: --experimental-wasm-eh. Requires code in //chrome?
