There was a problem hiding this comment.
I added a "miscellaneous TODO items" section on #10248 and added this there too (trying to ensure FIXME's like this are written down in issues)
My pleasure! Thanks! |

This patch is a subset of PR #10177. It adds support for tags in Wasmtime. Tags are used by the exception handling and stack switching proposals for typing and matching transfers of control.
This patch does not implement component model or C API support for tags. Issue #10252 tracks these two things.
