Does function pointers require strong GC reference?

[OwnageIsMagic]

If extern method captures function pointer (delegate* {managed or unmanaged}) do I need to keep strong reference to it on managed side?
Is function jited when it's address taken (&)? If not, it seems like I need to later update stored pointer, so it will point to actual implementation instead of stub (for better performance).
How does it play with tiered jit (Tier0 is never deallocated?)? What about assembly unloading?

The function pointer can be invalidated if the assembly is unloaded (see AssemblyLoadContext). But other than that, no; it's not like Marshal.GetFunctionPointerForDelegate() where you have to keep the delegate alive manually.
