--
-- First_Compiled_File is set to the name of the first file that is
-- compiled or that needs to be compiled. This is set to No_Name if no

--
-- Most_Recent_Obj_File is set to the full name of the most recent
-- object file found when no compilations are needed, that is when
-- First_Compiled_File is set to No_Name. When First_Compiled_File
-- is set then Most_Recent_Obj_File is set to No_Name.
--
-- Most_Recent_Obj_Stamp is the time stamp of Most_Recent_Obj_File.

-- If Do_Not_Execute is False and First_Compiled_File /= No_Name
-- the value of Main_Unit is always False.
-- Is this used any more??? It is certainly not used by gnatmake???
--
-- Compilation_Failures is a count of compilation failures. This count
-- is used to extract compilation failure reports with Extract_Failure.
--
-- Main_Index, when not zero, is the index of the main unit in source
-- file Main_Source which is a multi-unit source.
-- Zero indicates that Main_Source is a single unit source file.
--
-- Check_Readonly_Files set it to True to compile source files
-- which library files are read-only. When compiling GNAT predefined

-- Keep_Going when True keep compiling even in the presence of
-- compilation errors.
--
-- In_Place_Mode when True save library/object files in their object
-- directory if they already exist; otherwise, in the source directory.
--
-- Initialize_ALI_Data set it to True when you want to initialize ALI
-- data-structures. This is what you should do most of the time.
-- (especially the first time around when you call this routine).
-- This parameter is set to False to preserve previously recorded
-- ALI file data.
--
-- Max_Process is the maximum number of processes that should be spawned
-- to carry out compilations.
--
-- Flags in Package Opt Affecting Compile_Sources
-- -----------------------------------------------
--
-- Check_Object_Consistency set it to False to omit all consistency
-- checks between an .ali file and its corresponding object file.
-- When this flag is set to true, every time an .ali is read,
-- package Osint checks that the corresponding object file
-- exists and is more recent than the .ali.
--
-- Use of Name Table Info
-- ----------------------
--
-- All file names manipulated by Compile_Sources are entered into the
-- Names table. The Byte field of a source file is used to mark it.
--
-- Calling Compile_Sources Several Times
-- -------------------------------------
--
-- Upon return from Compile_Sources all the ALI data structures are left
-- intact for further browsing. HOWEVER upon entry to this routine ALI
-- data structures are re-initialized if parameter Initialize_ALI_Data
-- above is set to true. Typically this is what you want the first time
-- you call Compile_Sources. You should not load an ali file, call this
-- routine with flag Initialize_ALI_Data set to True and then expect
-- that ALI information to be around after the call. Note that the first
-- time you call Compile_Sources you better set Initialize_ALI_Data to
-- True unless you have called Initialize_ALI yourself.
--
-- Compile_Sources ALGORITHM : Compile_Sources (Main_Source)
-- -------------------------
--
-- 1. Insert Main_Source in a Queue (Q) and mark it.
--
-- 2. Let unit.adb be the file at the head of the Q. If unit.adb is
-- missing but its corresponding ali file is in an Ada library directory
-- (see below) then, remove unit.adb from the Q and goto step 4.
-- Otherwise, look at the files under the D (dependency) section of
-- unit.ali. If unit.ali does not exist or some of the time stamps do
-- not match, (re)compile unit.adb.
--
-- An Ada library directory is a directory containing Ada specs, ali
-- and object files but no source files for the bodies. An Ada library
-- directory is communicated to gnatmake by means of some switch so that
-- gnatmake can skip the sources whole ali are in that directory.
-- There are two reasons for skipping the sources in this case. Firstly,
-- Ada libraries typically come without full sources but binding and
-- linking against those libraries is still possible. Secondly, it would
-- be very wasteful for gnatmake to systematically check the consistency
-- of every external Ada library used in a program. The binder is
-- already in charge of catching any potential inconsistencies.
--
-- 3. Look into the W section of unit.ali and insert into the Q all
-- unmarked source files. Mark all files newly inserted in the Q.
-- Specifically, assuming that the W section looks like
--
-- W types%s types.adb types.ali
-- W unchecked_deallocation%s
-- W xref_tab%s xref_tab.adb xref_tab.ali
--
-- Then xref_tab.adb and types.adb are inserted in the Q if they are not
-- already marked.
-- Note that there is no file listed under W unchecked_deallocation%s
-- so no generic body should ever be explicitly compiled (unless the
-- Main_Source at the start was a generic body).
--
-- 4. Repeat steps 2 and 3 above until the Q is empty
--
-- Note that the above algorithm works because the units withed in
-- subunits are transitively included in the W section (with section) of
-- the main unit. Likewise the withed units in a generic body needed
-- during a compilation are also transitively included in the W section
-- of the originally compiled file.
