Looking at rs6000.opt I have found that the above command line switch

msched-prolog
Target Report Var(TARGET_SCHED_PROLOG) Init(1)
Schedule the start and end of the procedure
msched-epilog
Target Undocumented Var(TARGET_SCHED_PROLOG) VarExists
This appears of course to be wrong.
The latter probably ought to be TARGET_SCHED_EPILOG, if that
exists, eh?
Actually the second of the two is marked as Undocumented and hidden
silent option.
Most likely it was used during the compiler backend development for
optimization testing.
The best solution appears to be just to delete it, since it will give
proper meaning to the
msched-prolog, because as it is the first option may well alias the
second due to
different variable preinitalization and link order.
Apparently we also don't have test cases to actually verify that the
proper forms of these options are accepted and have the desired
effect...
