-A C expression that returns 1 if @var{insn} can be placed in delay
-slot number @var{n} of the epilogue.

-The argument @var{n} is an integer which identifies the delay slot now
-being considered (since different slots may have different rules of
-eligibility).  It is never negative and is always less than the number
-of epilogue delay slots (what @code{DELAY_SLOTS_FOR_EPILOGUE} returns).
-If you reject a particular insn for a given delay slot, in principle, it
-may be reconsidered for a subsequent delay slot.  Also, other insns may
-(at least in principle) be considered for the so far unfilled delay
-slot.
