[PATCH] D67208: [WebAssembly] Add -fwasm-exceptions for wasm EH

[Thomas Lively via Phabricator via cfe-commits]

tlively added a comment.

Thanks for the clarification. It makes sense to me that `-mexception-handling` only enables the architectural feature and a separate flag enables the behavior change. This is indeed consistent with how `-pthread` works.

What happens when users have exceptions in their code but don't pass `-fwasm-exceptions`? Do they get the old SJLJ emulated exception handling?
