Huh, so can it get different for both candidates? I think the stmt compare loop should be terminated on gsi_end_p of either iterator and return false for any remaining non-debug-stmts on the other. Thus, not walk all stmts twice here. As IPA split is run early I don't see how it should affect a real IPA pass though?
