316825a95bSMasahiro Yamada# We are using a recursive build, so we need to do a little thinking
326825a95bSMasahiro Yamada# to get the ordering right.
336825a95bSMasahiro Yamada#
346825a95bSMasahiro Yamada# Most importantly: sub-Makefiles should only ever modify files in
356825a95bSMasahiro Yamada# their own directory. If in some directory we have a dependency on
366825a95bSMasahiro Yamada# a file in another dir (which doesn't happen often, but it's often
376825a95bSMasahiro Yamada# unavoidable when linking the built-in.o targets which finally
386825a95bSMasahiro Yamada# turn into vmlinux), we will call a sub make in that other dir, and
396825a95bSMasahiro Yamada# after that we are sure that everything which is in that other dir
406825a95bSMasahiro Yamada# is now up to date.
416825a95bSMasahiro Yamada#
426825a95bSMasahiro Yamada# The only cases where we need to modify files which have global
436825a95bSMasahiro Yamada# effects are thus separated out and done before the recursive
446825a95bSMasahiro Yamada# descending is started. They are now explicitly listed as the
456825a95bSMasahiro Yamada# prepare rule.

50ffe29ebcSMasahiro Yamada# Normally, we echo the whole command before executing it. By making
51ffe29ebcSMasahiro Yamada# that echo $($(quiet)$(cmd)), we now have the possibility to set
