The original package System.Img_Enum is maintained in the sources +-- for bootstrapping with older versions of the compiler which expect to find +-- functions in this package. + +pragma Compiler_Unit; + +package System.Img_Enum_New is + pragma Pure; + + procedure Image_Enumeration_8 + (Pos : Natural; + S : in out String; + P : out Natural; + Names : String; + Indexes : System.Address); + -- Used to compute Enum'Image (Str) where Enum is some enumeration type + -- other than those defined in package Standard. Names is a string with + -- a lower bound of 1 containing the characters of all the enumeration + -- literals concatenated together in sequence. Indexes is the address of + -- an array of type array (0 .. N) of Natural_8, where N is the number of + -- enumeration literals in the type. The Indexes values are the starting + -- subscript of each enumeration literal, indexed by Pos values, with an + -- extra entry at the end containing Names'Length + 1. The reason that + -- Indexes is passed by address is that the actual type is created on the + -- fly by the expander. The desired 'Image value is stored in S (1 .. P) + -- and P is set on return. The caller guarantees that S is long enough to + -- hold the result and that the lower bound is 1. + + procedure Image_Enumeration_16 + (Pos : Natural; + S : in out String; + P : out Natural; + Names : String; + Indexes : System.Address); + -- Identical to Set_Image_Enumeration_8 except that it handles types using + -- array (0 ..
