Ada provides ‘Image’ and ‘Value’ functions for every enumeration type, and so the compiler needs to build up a table of information that allows an internal enumeration value to be turned into a string, and vice-versa. The enum_integer_table and the enum_image_table are used for that purpose. If you want to suppress the generation of such a table, you can use Ada’s “Discard_Names” pragma. Having done that, then Ada code that uses ‘Image or ‘Value will no longer work as expected, and instead will use numeric literals for input and output.
