--- Comment #8 from Martin Liška <marxin at gcc dot gnu.org> ---
So the problem is caused by ICF which makes a symbol to have no direct calls
(and no references). As a result IPA CP triggers verification failure. I hope
the right solution is to append TODO_remove_function for ICF IPA pass.

I've been testing following patch:

diff --git a/gcc/ipa-icf.c b/gcc/ipa-icf.c
index 31fcbec..56f59a9 100644
--- a/gcc/ipa-icf.c

 };

 class pass_ipa_icf : public ipa_opt_pass_d
