Details

In bug 1595031 we implemented support for wasm functions returning multiple values to JS, and JS functions returning multiple values to wasm. However calls are only supported via the InterpEntry / InterpExit; the JIT ABI isn't supported. See bug 1595031 for a discussion of the issues.

Optimization item, bumping to P3.

Priority: P2 → P3

Not urgent until multi-value ABI becomes a thing for wasm producers, if then. Also we await JS tuples. Also we await a better system for generating stubs code, including rooting support.

Severity: normal → S3
