Generation of loaddefs.el is annoyingly slow (takes more than 1 minute on a fast machine, almost 2 min on fencepost.gnu.org), so running it on every pull should be avoided. The reason for this are two rules. One is in src/Makefile.in: $(lispsource)/loaddefs.el: $(VCSWITNESS) | bootstrap-emacs$(EXEEXT) $(MAKE) -C ../lisp autoloads EMACS="$(bootstrap_exe)" This triggers each "git pull" due to $(VCSWITNESS). The other rule is in lisp/Makefile.in: autoloads .PHONY: $(lisp)/loaddefs.el Why should loaddefs.el be treated as a "phony" target? It's a real file. This was introduced in d703a4d, whose log message says just this: * lisp/Makefile.in (PHONY_EXTRAS): New macro. (.PHONY): Depend on it, and on $(lisp)/loaddefs.el, so that the relevant files' time stamps are ignored. That says nothing about the rationale, and I couldn't find any discussions of the change. Paul, could you please explain why would it be a bad idea to remove the "phony" status from loaddefs.el?
