This repository is a clone of github.com/WebAssembly/spec/. It is meant for discussion, prototype specification and implementation of a proposal to add garbage collection (GC) support to WebAssembly.

• See the overview for a high-level summary and rationale of the proposal. Note: the concrete details here are out of date.

• See the MVP for an up-to-date overview of the concrete language extensions that are proposed for the first stage of GC support in Wasm.

• See the Post-MVP for possible future extensions in later stages.

• See the modified spec for the completed spec for the first-stage proposal described in MVP.md.

This repository is based on the function references proposal as a baseline and includes all respective changes.

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.
