--  This package contains a procedure for runtime concatenation of eight string
--  operands. It is used when we want to save space in the generated code.

pragma Compiler_Unit;

package System.Concat_8 is

   procedure Str_Concat_8
     (R                              : out String;
      S1, S2, S3, S4, S5, S6, S7, S8 : String);
   --  Performs the operation R := S1 & S2 & S3 & S4 & S5 & S6 & S7 & S8.
   --  The bounds of R are known to be correct (usually set by a call to the
   --  Str_Concat_Bounds_8 procedure below), so no bounds checks are required,
   --  and it is known that none of the input operands overlaps R. No
   --  assumptions can be made about the lower bounds of any of the operands.

   procedure Str_Concat_Bounds_8
     (Lo, Hi                         : out Natural;
      S1, S2, S3, S4, S5, S6, S7, S8 : String);
   --  Assigns to Lo..Hi the bounds of the result of concatenating the eight
   --  given strings, following the rules in the RM regarding null operands.
