If unit.ali does not exist or some of the time stamps do 998 -- not match, (re)compile unit.adb. 999 -- 1000 -- An Ada library directory is a directory containing Ada specs, ali 1001 -- and object files but no source files for the bodies. An Ada library 1002 -- directory is communicated to gnatmake by means of some switch so that 1003 -- gnatmake can skip the sources whole ali are in that directory. 1004 -- There are two reasons for skipping the sources in this case. Firstly, 1005 -- Ada libraries typically come without full sources but binding and 1006 -- linking against those libraries is still possible. Secondly, it would 1007 -- be very wasteful for gnatmake to systematically check the consistency 1008 -- of every external Ada library used in a program. The binder is 1009 -- already in charge of catching any potential inconsistencies. 1010 -- 1011 -- 3. Look into the W section of unit.ali and insert into the Q all 1012 -- unmarked source files. Mark all files newly inserted in the Q. 1013 -- Specifically, assuming that the W section looks like 1014 -- 1015 -- W types%s types.adb types.ali 1016 -- W unchecked_deallocation%s 1017 -- W xref_tab%s xref_tab.adb xref_tab.ali 1018 -- 1019 -- Then xref_tab.adb and types.adb are inserted in the Q if they are not 1020 -- already marked. 1021 -- Note that there is no file listed under W unchecked_deallocation%s 1022 -- so no generic body should ever be explicitly compiled (unless the 1023 -- Main_Source at the start was a generic body). 1024 -- 1025 -- 4.
