31 6825a95bSMasahiro Yamada# We are using a recursive build, so we need to do a little thinking
32 6825a95bSMasahiro Yamada# to get the ordering right.
33 6825a95bSMasahiro Yamada#
34 6825a95bSMasahiro Yamada# Most importantly: sub-Makefiles should only ever modify files in
35 6825a95bSMasahiro Yamada# their own directory. If in some directory we have a dependency on
36 6825a95bSMasahiro Yamada# a file in another dir (which doesn't happen often, but it's often
37 6825a95bSMasahiro Yamada# unavoidable when linking the built-in.o targets which finally
38 6825a95bSMasahiro Yamada# turn into vmlinux), we will call a sub make in that other dir, and
39 6825a95bSMasahiro Yamada# after that we are sure that everything which is in that other dir
40 6825a95bSMasahiro Yamada# is now up to date.
41 6825a95bSMasahiro Yamada#
42 6825a95bSMasahiro Yamada# The only cases where we need to modify files which have global
43 6825a95bSMasahiro Yamada# effects are thus separated out and done before the recursive
44 6825a95bSMasahiro Yamada# descending is started. They are now explicitly listed as the
45 6825a95bSMasahiro Yamada# prepare rule.
