-// Temporary option to compare overall performance change when moving from the

-// benchmarking during the transition from SD to MI scheduling. Once armv7 makes
-// the switch, it should go away. The normal way to enable/disable the
-// MachineScheduling pass itself is by using -enable-misched. For targets that
-// already use MI sched (via MySubTarget::enableMachineScheduler())
-// -misched-bench=false negates the subtarget hook.
