It is not worth moving it at this stage. + +-- The compiler will generate references to the subprograms in this package +-- when expanding stream attributes for the above mentioned types. Example: + +-- String'Output (Some_Stream, Some_String); + +-- will be expanded into: + +-- String_Output (Some_Stream, Some_String); +-- or +-- String_Output_Blk_IO (Some_Stream, Some_String); + +-- String_Output form is used if pragma Restrictions (No_String_Optimziations) +-- is active, which requires element by element operations. The BLK_IO form +-- is used if this restriction is not set, allowing block optimization. + +-- Note that if System.Stream_Attributes.Block_IO_OK is False, then the BLK_IO +-- form is treated as equivalent to the normal case, so that the optimization +-- is inhibited anyway, regardless of the setting of the restriction. This +-- handles versions of System.Stream_Attributes (in particular the XDR version +-- found in s-stratt-xdr) which do not permit block io optimization. + +pragma Compiler_Unit_Warning; + +with Ada.Streams;
