Before calling this routine make sure Namet has been -- initialized. This routine can be called repeatedly with different -- Main_Source file as long as all the source (-I flags), library -- (-B flags) and ada library (-A flags) search paths between calls are -- *exactly* the same. The default directory must also be the same. -- -- Args contains the arguments to use during the compilations. -- The lower bound of Args must be 1. -- -- First_Compiled_File is set to the name of the first file that is -- compiled or that needs to be compiled. This is set to No_Name if no -- compilations were needed. -- -- Most_Recent_Obj_File is set to the full name of the most recent -- object file found when no compilations are needed, that is when -- First_Compiled_File is set to No_Name. When First_Compiled_File -- is set then Most_Recent_Obj_File is set to No_Name. -- -- Most_Recent_Obj_Stamp is the time stamp of Most_Recent_Obj_File. -- -- Main_Unit is set to True if Main_Source can be a main unit. -- If Do_Not_Execute is False and First_Compiled_File /= No_Name -- the value of Main_Unit is always False. -- Is this used any more??? It is certainly not used by gnatmake??? -- -- Compilation_Failures is a count of compilation failures. This count -- is used to extract compilation failure reports with Extract_Failure. -- -- Main_Index, when not zero, is the index of the main unit in source -- file Main_Source which is a multi-unit source. -- Zero indicates that Main_Source is a single unit source file. -- -- Check_Readonly_Files set it to True to compile source files -- which library files are read-only. When compiling GNAT predefined -- files the "-gnatg" flag is used. -- -- Do_Not_Execute set it to True to find out the first source that -- needs to be recompiled, but without recompiling it. This file is -- saved in First_Compiled_File. -- -- Force_Compilations forces all compilations no matter what but -- recompiles read-only files only if Check_Readonly_Files -- is set. -- -- Keep_Going when True keep compiling even in the presence of -- compilation errors. -- -- In_Place_Mode when True save library/object files in their object -- directory if they already exist; otherwise, in the source directory. -- -- Initialize_ALI_Data set it to True when you want to initialize ALI -- data-structures. This is what you should do most of the time. -- (especially the first time around when you call this routine). -- This parameter is set to False to preserve previously recorded -- ALI file data. -- -- Max_Process is the maximum number of processes that should be spawned -- to carry out compilations. -- -- Flags in Package Opt Affecting Compile_Sources -- ----------------------------------------------- -- -- Check_Object_Consistency set it to False to omit all consistency -- checks between an .ali file and its corresponding object file. -- When this flag is set to true, every time an .ali is read, -- package Osint checks that the corresponding object file -- exists and is more recent than the .ali. -- -- Use of Name Table Info -- ---------------------- -- -- All file names manipulated by Compile_Sources are entered into the -- Names table. The Byte field of a source file is used to mark it. -- -- Calling Compile_Sources Several Times -- ------------------------------------- -- -- Upon return from Compile_Sources all the ALI data structures are left -- intact for further browsing. HOWEVER upon entry to this routine ALI -- data structures are re-initialized if parameter Initialize_ALI_Data -- above is set to true. Typically this is what you want the first time -- you call Compile_Sources. You should not load an ali file, call this -- routine with flag Initialize_ALI_Data set to True and then expect -- that ALI information to be around after the call. Note that the first -- time you call Compile_Sources you better set Initialize_ALI_Data to -- 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. procedure Initialize (Project_Node_Tree : out Project_Node_Tree_Ref); -- Performs default and package initialization. Therefore, -- Compile_Sources can be called by an external unit. procedure Link (ALI_File : File_Name_Type; Args : Argument_List; Success : out Boolean); -- Links ALI_File.
