It is called from pass_feedback_split_functions:

  NEXT_PASS (pass_all_early_optimizations);
    {
       ...
    }
  NEXT_PASS (pass_ipa_free_inline_summary);
  NEXT_PASS (pass_ipa_tree_profile);
    {
      struct opt_pass **p = &pass_ipa_tree_profile.pass.sub;
      NEXT_PASS (pass_feedback_split_functions);
    }

OK to install?

Thanks.
