--- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Or, if you for some reason really need some debug markers, do you really need also debug bind stmts in there? E.g. in light of the AIX bootstrap failure, having just markers before labels shouldn't be that harmful, because they shouldn't have operands, but having there debug binds is very problematic.
