I've done a little experimenting to get a feel for this. I've looked at the work done toward the GCC compile server but decided that I want to concentrate on GNAT trees (whereas the compile server targets the GNU trees.) Also I am aiming somewhat lower - not making a separate compile server process but rather extending gnat1 to handle multiple files in a single invocation. The current GNAT code makes a strong assumption that there be only one main unit, and this Main_Unit be located at index 0 of Lib.Units.Table (see procedure Lib.Load.Load_Main_Source). I am currently looking at having each main unit supplied on the gnat1 command line overwrite the Main_Unit in the Units table. What do you think of this approach? The attached patch sets the stage for passing multiple source files to a single gnat1 invocation. (Beware, this is a rough cut. Best use "svn diff --diff-cmd diff -x -uw" after applying as there are many changes that only affect indentation.) Thanks, Oliver
