On targets that use instruction scheduling, this option controls the
amount of debugging output the scheduler prints. This information is
written to standard error, unless @option{-fdump-rtl-sched1} or
@option{-fdump-rtl-sched2} is specified, in which case it is output
to the usual dump listing file, @file{.sched1} or @file{.sched2}
respectively. However for @var{n} greater than nine, the output is
always printed to standard error.

For @var{n} greater than zero, @option{-fsched-verbose} outputs the
same information as @option{-fdump-rtl-sched1} and @option{-fdump-rtl-sched2}.
