Only valid to call if name has been set. + + function More_Source_Files return Boolean; + -- Indicates whether more source file remain to be processed. Returns + -- False right away if no source files, or if all source files have + -- been processed. + + function Next_Main_Source return File_Name_Type; + -- This function returns the name of the next main source file specified + -- on the command line. It is an error to call Next_Main_Source if no more + -- source files exist (i.e. Next_Main_Source may be called only if a + -- previous call to More_Source_Files returned True). This name is the + -- simple file name (without any directory information). + + ------------------------------ + -- Debug Source File Output -- + ------------------------------ + + -- These routines are used by the compiler to generate the debug source + -- file for the Debug_Generated_Code (-gnatD switch) option. Note that + -- debug source file writing occurs at a completely different point in + -- the processing from library information output, or representation + -- output, so the code in the body can assume that no two of these + -- functions are ever used at the same time. + + function Create_Debug_File (Src : File_Name_Type) return File_Name_Type; + -- Given the simple name of a source file, this routine creates the + -- corresponding debug file, and returns its full name. + + procedure Write_Debug_Info (Info : String); + -- Writes contents of given string as next line of the current debug + -- source file created by the most recent call to Create_Debug_File. + -- Info does not contain end of line or other formatting characters. + + procedure Close_Debug_File; + -- Close current debug file created by the most recent call to + -- Create_Debug_File. + + function Debug_File_Eol_Length return Nat; + -- Returns the number of characters (1 for NL, 2 for CR/LF) written + -- at the end of each line by Write_Debug_Info. + + -------------------------------- + -- Representation File Output -- + -------------------------------- + + -- These routines are used by the compiler to generate the representation + -- information to a file if this option is specified (-gnatR?s switch). + -- Note that the writing of this file occurs at a completely different + -- point in the processing from library information output, or from + -- debug file output, so the code in the body can assume that no two + -- of these functions are ever used at the same time. + + -- Note: these routines are called from Repinfo, but are not called + -- directly, since we do not want Repinfo to depend on Osint. That + -- would cause a lot of unwanted junk to be dragged into ASIS.
