Yes, either any of these, or if a constprop function is generated it is either
in the .init* section or it doesn't take a reference to a variable in .init*.

It is not in .init*, but that's ok: the reference from .init to .text is
present in the original source. It's the reference from .text* to .init* which
is not present in the source but is generated by gcc that is the issue.
