--- Comment #10 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Won't this invoke it all the time if the timestamp of the generated files is older than timestamp of the sources from which it is generated? Which was the reason I've used stamp files in the #c5 patch similarly how we use it almost everywhere else when using move-if-change?
