--  This package contains the generic functions which are instantiated with
--  predefined integer and real types to generate the runtime exponentiation
--  functions called by expanded code generated by Expand_Op_Expon. This
--  version of the package contains routines that are compiled with overflow
--  checks suppressed, so they are called for exponentiation operations which
--  do not require overflow checking

package System.Exn_Gen is
pragma Pure (System.Exn_Gen);

   --  Exponentiation for float types (checks off)

   generic
      type Type_Of_Base is digits <>;
   function Exn_Float_Type
     (Left : Type_Of_Base; Right : Integer) return Type_Of_Base;

   --  Exponentiation for signed integer base

   generic
      type Type_Of_Base is range <>;
   function Exn_Integer_Type
     (Left : Type_Of_Base; Right : Natural) return Type_Of_Base;

end System.Exn_Gen;
