-- 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.
