--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
If the final result is -g0, then clearing flag_var_tracking_assignments is
desirable, if the final result is -g and any of the inputs have debug stmts,
then either you need to turn flag_var_tracking_assignments whenever any inputs
has debug stmts, or remove the debug stmts if you want to keep it cleared.
