968 -- time you call Compile_Sources you better set Initialize_ALI_Data to
969 -- True unless you have called Initialize_ALI yourself.
971 -- Compile_Sources ALGORITHM : Compile_Sources (Main_Source)
972 -- -------------------------
974 -- 1. Insert Main_Source in a Queue (Q) and mark it.
976 -- 2. Let unit.adb be the file at the head of the Q. If unit.adb is
977 -- missing but its corresponding ali file is in an Ada library directory
978 -- (see below) then, remove unit.adb from the Q and goto step 4.
979 -- Otherwise, look at the files under the D (dependency) section of
980 -- unit.ali. If unit.ali does not exist or some of the time stamps do
981 -- not match, (re)compile unit.adb.
983 -- An Ada library directory is a directory containing Ada specs, ali
984 -- and object files but no source files for the bodies. An Ada library
985 -- directory is communicated to gnatmake by means of some switch so that
986 -- gnatmake can skip the sources whole ali are in that directory.
987 -- There are two reasons for skipping the sources in this case. Firstly,
988 -- Ada libraries typically come without full sources but binding and
989 -- linking against those libraries is still possible. Secondly, it would
990 -- be very wasteful for gnatmake to systematically check the consistency
991 -- of every external Ada library used in a program. The binder is
992 -- already in charge of catching any potential inconsistencies.
994 -- 3. Look into the W section of unit.ali and insert into the Q all
995 -- unmarked source files. Mark all files newly inserted in the Q.
996 -- Specifically, assuming that the W section looks like
998 -- W types%s types.adb types.ali
999 -- W unchecked_deallocation%s
1000 -- W xref_tab%s xref_tab.adb xref_tab.ali
1002 -- Then xref_tab.adb and types.adb are inserted in the Q if they are not
1004 -- Note that there is no file listed under W unchecked_deallocation%s
1005 -- so no generic body should ever be explicitly compiled (unless the
1006 -- Main_Source at the start was a generic body).
1008 -- 4. Repeat steps 2 and 3 above until the Q is empty
1010 -- Note that the above algorithm works because the units withed in
1011 -- subunits are transitively included in the W section (with section) of
1012 -- the main unit. Likewise the withed units in a generic body needed
1013 -- during a compilation are also transitively included in the W section
1014 -- of the originally compiled file.
