--- Comment #47 from Segher Boessenkool <segher at gcc dot gnu.org> --- (In reply to Sam James from comment #46) > Even partially making the build less recursive would likely help a fair bit. It will help a bit, sure, but not nearly as much as you perhaps hope for. There are quite a few "synchronisation" points where nothing after it can be done until everything before it has been done. Partly this is just because we have a three-stage bootstrap, but also there are some generator programs that everything else depends on (on its output that is), and those are real chokepoints. Also, recursive make is a scourge of humanity, for sure, but fixing this has to be done in autoxxxx first and foremost.
