--- 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 +++ b/gcc/ipa-icf.c @@ -3049,7 +3049,7 @@ const pass_data pass_data_ipa_icf = 0, /* properties_provided */ 0, /* properties_destroyed */ 0, /* todo_flags_start */ - 0, /* todo_flags_finish */ + TODO_remove_functions, /* todo_flags_finish */ }; class pass_ipa_icf : public ipa_opt_pass_d Martin
