+/// \file
+/// This file implements a pass that will conditionally reset a machine
+/// function as if it was just created. This is used to provide a fallback
+/// mechanism when GlobalISel fails, thus the condition for the reset to
+/// happen is that the MachineFunction has the FailedISel property.
