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. - - procedure Globalize (Success : out Boolean); - -- Call the CodePeer globalizer on all the project's object directories, - -- or on the current directory if no projects. - - procedure Initialize - (Project_Node_Tree : out Project_Node_Tree_Ref; - Env : out Prj.Tree.Environment); - -- Performs default and package initialization.
