This repository holds a proposal for adding exception handling to WebAssembly.

The exception handling proposal depends on the reference-types proposal and on the multi-value proposal.

The repository is a clone of WebAssembly/spec, first rebased on the spec of its dependency reference-types, and then merged with the other dependency multi-value.

The remainder of the document has contents of the two README files of the dependencies: reference-types/README.md and multi-value/README.md.

This repository is a clone of github.com/WebAssembly/spec/. It is meant for discussion, prototype specification and implementation of a proposal to add support for basic reference types to WebAssembly.

• See the overview for a summary of the proposal.

• See the modified spec for details.

Original README from upstream repository follows...

This repository holds a prototypical reference implementation for WebAssembly, which is currently serving as the official specification. Eventually, we expect to produce a specification either written in human-readable prose or in a formal specification language.

It also holds the WebAssembly testsuite, which tests numerous aspects of conformance to the spec.

View the work-in-progress spec at webassembly.github.io/spec.

At this time, the contents of this repository are under development and known to be "incomplet and inkorrect".

Participation is welcome. Discussions about new features, significant semantic changes, or any specification change likely to generate substantial discussion should take place in the WebAssembly design repository first, so that this spec repository can remain focused. And please follow the guidelines for contributing.
