Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Component|gcov-profile |middle-end --- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> --- I suspect the issue is dump_enumerated_decls is not skipping GIMPLE_LABEL as GIMPLE_LABEL does not effect different code generation only additional labels and at -O0 GCC emits extra labels for better debug info.
