1831920 - Add support for casting function types

Status: RESOLVED FIXED

(Core :: JavaScript: WebAssembly, task, P2)

Description

[Ryan Hunt [:rhunt]]

The casting instructions can support downcasting to a specific function type. We currently don't support this because our function object representation doesn't have the type information easily accessible.

There is an r+ patch which didn't land and no activity in this bug for 2 weeks.
:bvisness, could you have a look please?
If you still have some work to do, you can add an action "Plan Changes" in Phabricator.
For more information, please visit BugBot documentation.
