--- Comment #8 from Jakub Jelinek <jakub at gcc dot gnu.org> 2013-01-08 13:28:56 UTC --- Note this isn't limited to dbxout.c, pretty much all *out.c debug backends but dwarf2out.c suffer from these issues, they all emit assembly immediately, only dwarf2out.c just creates data structures to be used later on.
