--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> --- And implementation-wise we should disregard always-inline on indirect calls (which would mean putting always-inline on the actual call stmt and preserve this when devirtualizing). So IMO it's a QOI issue with the way we document this as "invalid".
