553 ## Bootstrapping right is difficult because of the circular dependencies.
554 ## Furthermore, we have to deal with the fact that many compilation targets
555 ## such as loaddefs.el or *.elc can typically be produced by any old
556 ## Emacs executable, so we would like to avoid rebuilding them whenever
557 ## we build a new Emacs executable.
558 ## To solve the circularity, we use 2 different Emacs executables,
559 ## "emacs" is the main target and "bootstrap-emacs" is the one used
560 ## to build the *.elc and loaddefs.el files.
561 ## To solve the freshness issue, we used to use a third file "witness-emacs"
562 ## which was used to witness the fact that there is a bootstrap-emacs
563 ## executable, and then have dependencies on witness-emacs rather than
564 ## bootstrap-emacs, but that lead to problems in parallel builds (because
565 ## witness-emacs needed to be free from dependencies (to avoid rebuilding
566 ## it), so it was compiled in parallel, leading typically to having 2
567 ## processes dumping bootstrap-emacs at the same time).
568 ## So instead, we replace the witness-emacs dependencies by conditional
569 ## bootstrap-dependencies (via $(BOOTSTRAPEMACS)). Of course, since we do
570 ## not want to rely on GNU Make features, we have to rely on an external
571 ## script to do the conditional part of the dependency
572 ## (i.e. see the $(SUBDIR) rule ../Makefile.in).
576 ## These suffix rules do not allow additional dependencies, sadly, so
577 ## instead of adding a $(BOOTSTRAPEMACS) dependency here, we add it
579 ## With GNU Make, we would just say "%.el : %.elc $(BOOTSTRAPEMACS)"
