- -- Source File Input --
- -----------------------

- -- source files and the subsidiary source files (e.g. with'ed units), and
- -- also by the binder to check presence/time stamps of sources.
-
- procedure Read_Source_File
- (N : File_Name_Type;
- Lo : Source_Ptr;
- Hi : out Source_Ptr;
- Src : out Source_Buffer_Ptr;
- T : File_Type := Source);
- -- Allocates a Source_Buffer of appropriate length and then reads the
- -- entire contents of the source file N into the buffer. The address of
- -- the allocated buffer is returned in Src.
- --
- -- Each line of text is terminated by one of the sequences:
- --
- -- CR
- -- CR/LF
- -- LF/CR
- -- LF
-
- -- The source is terminated by an EOF (16#1A#) character, which is
- -- the last charcater of the returned source bufer (note that any
- -- EOF characters in positions other than the last source character
- -- are treated as representing blanks).
- --
- -- The logical lower bound of the source buffer is the input value of Lo,
- -- and on exit Hi is set to the logical upper bound of the source buffer.
- -- Note that the returned value in Src points to an array with a physical
- -- lower bound of zero. This virtual origin addressing approach means that
- -- a constrained array pointer can be used with a low bound of zero which
- -- results in more efficient code.
- --
- -- If the given file cannot be opened, then the action depends on whether
- -- this file is the current main unit (i.e. its name matches the name
- -- returned by the most recent call to Next_Main_Source). If so, then the
- -- failure to find the file is a fatal error, an error message is output,
- -- and program execution is terminated. Otherwise (for the case of a
- -- subsidiary source loaded directly or indirectly using with), a file
- -- not found condition causes null to be set as the result value.
- --
- -- Note that the name passed to this function is the simple file name,
- -- without any directory information. The implementation is responsible
- -- for searching for the file in the appropriate directories.
- --
- -- Note the special case that if the file name is gnat.adc, then the
- -- search for the file is done ONLY in the directory corresponding to
- -- the current compilation environment, i.e. in the same directory
- -- where the ali and object files will be written.
-
- function Full_Source_Name return File_Name_Type;
- function Current_Source_File_Stamp return Time_Stamp_Type;
- -- Returns the full name/time stamp of the source file most recently read

- -- cannot be located No_File is returned for the first routine and an
- -- all blank time stamp is returned for the second (this is not an error
- -- situation). The full name includes the appropriate directory
- -- information. The source file directory lookup penalty is incurred
- -- every single time the routines are called unless you have previously
- -- called Source_File_Data (Cache => True). See below.
-
- function Current_File_Index return Int;
- -- Return the index in its source file of the current main unit

- -- path until a source file with time stamp matching T is found. If
- -- none is found returns No_File.
-
- procedure Source_File_Data (Cache : Boolean);
- -- By default source file data (full source file name and time stamp)
- -- are looked up every time a call to Full_Source_Name (N) or
- -- Source_File_Stamp (N) is made. This may be undesirable in certain
- -- applications as this is uselessly slow if source file data does not
- -- change during program execution. When this procedure is called with
- -- Cache => True access to source file data does not encurr a penalty if
- -- this data was previously retrieved.
-
- -------------------------------------------
- -- Representation of Library Information --
- -------------------------------------------
-
- -- Associated with each compiled source file is library information,
- -- a string of bytes whose exact format is described in the body of
- -- Lib.Writ. Compiling a source file generates this library information
- -- for the compiled unit, and access the library information for units
- -- that were compiled previously on which the unit being compiled depends.
-
- -- How this information is stored is up to the implementation of this
- -- package. At the interface level, this information is simply associated
- -- with its corresponding source.
-
- -- Several different implementations are possible:
-
- -- 1. The information could be directly associated with the source file,
- -- e.g. placed in a resource fork of this file on the Mac, or on
- -- MS-DOS, written to the source file after the end of file mark.
-
- -- 2. The information could be written into the generated object module
- -- if the system supports the inclusion of arbitrary informational
- -- byte streams into object files. In this case there must be a naming
- -- convention that allows object files to be located given the name of
- -- the corresponding source file.
-
- -- 3. The information could be written to a separate file, whose name is
- -- related to the name of the source file by a fixed convention.
-
- -- Which of these three methods is chosen depends on the constraints of the
- -- host operating system. The interface described here is independent of
- -- which of these approaches is used.
-

- -- source of the library information from the library information file
- -- whose name is given by the parameter Name.
- --
- -- See description of Read_Source_File for details on the format of the
- -- returned text buffer (the format is identical). THe lower bound of
- -- the Text_Buffer is always zero
- --
- -- If the specified file cannot be opened, then the action depends on
- -- Fatal_Err. If Fatal_Err is True, an error message is given and the
- -- compilation is abandoned. Otherwise if Fatal_Err is False, then null
- -- is returned. Note that the Lib_File is a simple name which does not
- -- include any directory information. The implementation is responsible
- -- for searching for the file in appropriate directories.
- --
- -- If Opt.Check_Object_Consistency is set to True then this routine
- -- checks whether the object file corresponding to the Lib_File is
- -- consistent with it. The object file is inconsistent if the object
- -- does not exist or if it has an older time stamp than Lib_File.
- -- This check is not performed when the Lib_File is "locked" (i.e.
- -- read/only) because in this case the object file may be buried
