972 -- time you call Compile_Sources you better set Initialize_ALI_Data to
973 -- True unless you have called Initialize_ALI yourself.
975 -- Compile_Sources ALGORITHM : Compile_Sources (Main_Source)
976 -- -------------------------
978 -- 1. Insert Main_Source in a Queue (Q) and mark it.
980 -- 2. Let unit.adb be the file at the head of the Q. If unit.adb is
981 -- missing but its corresponding ali file is in an Ada library directory
982 -- (see below) then, remove unit.adb from the Q and goto step 4.
983 -- Otherwise, look at the files under the D (dependency) section of
984 -- unit.ali. If unit.ali does not exist or some of the time stamps do
985 -- not match, (re)compile unit.adb.
987 -- An Ada library directory is a directory containing Ada specs, ali
988 -- and object files but no source files for the bodies. An Ada library
989 -- directory is communicated to gnatmake by means of some switch so that
990 -- gnatmake can skip the sources whole ali are in that directory.
991 -- There are two reasons for skipping the sources in this case. Firstly,
992 -- Ada libraries typically come without full sources but binding and
993 -- linking against those libraries is still possible. Secondly, it would
994 -- be very wasteful for gnatmake to systematically check the consistency
995 -- of every external Ada library used in a program. The binder is
996 -- already in charge of catching any potential inconsistencies.
998 -- 3. Look into the W section of unit.ali and insert into the Q all
999 -- unmarked source files. Mark all files newly inserted in the Q.
1000 -- Specifically, assuming that the W section looks like
1002 -- W types%s types.adb types.ali
1003 -- W unchecked_deallocation%s
1004 -- W xref_tab%s xref_tab.adb xref_tab.ali
1006 -- Then xref_tab.adb and types.adb are inserted in the Q if they are not
1008 -- Note that there is no file listed under W unchecked_deallocation%s
1009 -- so no generic body should ever be explicitly compiled (unless the
1010 -- Main_Source at the start was a generic body).
1012 -- 4. Repeat steps 2 and 3 above until the Q is empty
1014 -- Note that the above algorithm works because the units withed in
1015 -- subunits are transitively included in the W section (with section) of
1016 -- the main unit. Likewise the withed units in a generic body needed
1017 -- during a compilation are also transitively included in the W section
1018 -- of the originally compiled file.
