+ --
+ -- Use of Name Table Info
+ -- ----------------------
+ --
+ -- All file names manipulated by Compile_Sources are entered into the

+ --
+ -- 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.
