--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Well, guess the warning could have many false positives.
Anyway, if you code for such warning, you could as well just assume the
attribute on the functions and if you set it before IPA, perhaps you could even
propagate it during IPA, then functions can make use of those.
Though, such implicit attributes unlike explicit ones could be used (or even
set) only if decl_binds_to_current_def_p (decl), otherwise you can very well
have
void *foo (void) { return "abc"; } in current CU and foo be preempted during
dynamic linking and the preempted foo could return NULL.
