-- GNAT was originally developed by the GNAT team at New York University. --
-- Extensive contributions were provided by Ada Core Technologies Inc. --
-- --
------------------------------------------------------------------------------
-- This package contains the low level, operating system routines used only
-- in the GNAT compiler for command line processing and file input output.
package Osint.C is
procedure Set_Output_Object_File_Name (Name : String);
-- Called by the subprogram processing the command line when an
-- output object file name is found.
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. So
-- what we do is we have Initialize set the addresses of these three
-- procedures in appropriate variables in Repinfo, so that they can
-- be called indirectly without creating a dependence.
procedure Creat_Repinfo_File (Src : File_Name_Type);
-- Given the simple name of a source file, this routine creates the
-- corresponding file to hold representation information
procedure Write_Repinfo_Line (Info : String);
-- Writes contents of given string as next line of the current debug
-- source file created by the most recent call to Create_Repinfo_File.
-- Info does not contain end of line or other formatting characters.
procedure Close_Repinfo_File;
-- Close current debug file created by the most recent call to
-- Create_Repinfo_File.
--------------------------------
-- Library Information Output --
--------------------------------
-- These routines are used by the compiler to generate the library
-- information file for the main source file being compiled. See section
-- above for a discussion of how library information files are stored.
procedure Create_Output_Library_Info;
-- Creates the output library information file for the source file which
-- is currently being compiled (i.e. the file which was most recently
-- returned by Next_Main_Source).
procedure Write_Library_Info (Info : String);
-- Writes the contents of the referenced string to the library information
-- file for the main source file currently being compiled (i.e. the file
-- which was most recently opened with a call to Read_Next_File). Info
-- represents a single line in the file, but does not contain any line
-- termination characters. The implementation of Write_Library_Info is
-- responsible for adding necessary end of line and end of file control
-- characters to the generated file.
procedure Close_Output_Library_Info;
-- Closes the file created by Create_Output_Library_Info, flushing any
-- buffers etc from writes by Write_Library_Info.
procedure Read_Library_Info
(Name : out File_Name_Type;
Text : out Text_Buffer_Ptr);
-- The procedure version of Read_Library_Info is used from the compiler
-- to read an existing ali file associated with the main unit. If the
-- ALI file exists, then its file name is returned in Name, and its
-- text is returned in Text. If the file does not exist, then Text is
-- set to null.
--------------------------------
-- Semantic Tree Input-Output --
--------------------------------
procedure Tree_Create;
-- Creates the tree output file for the source file which is currently
-- being compiled (i.e. the file which was most recently returned by
-- Next_Main_Source), and initializes Tree_IO.Tree_Write for output.
procedure Tree_Close;
-- Closes the file previously opened by Tree_Create
end Osint.C;
