            Bug ID: 205930
           Summary: -funroll-loop options is undocument
           Product: Base System
           Version: 11.0-CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Many People
          Priority: ---
         Component: bin
          Assignee: freebsd-bugs at FreeBSD.org
          Reporter: kargl at FreeBSD.org

cc accepts the undocumented option -funroll-loops.  As
it is undocumented, one has no idea what it does.  If
cc does unrolling, there appears to be no way to control
the level of unrolling.  Please fix.
