26 6825a95bSMasahiro Yamada# We are using a recursive build, so we need to do a little thinking
27 6825a95bSMasahiro Yamada# to get the ordering right.
28 6825a95bSMasahiro Yamada#
29 6825a95bSMasahiro Yamada# Most importantly: sub-Makefiles should only ever modify files in
30 6825a95bSMasahiro Yamada# their own directory. If in some directory we have a dependency on
31 6825a95bSMasahiro Yamada# a file in another dir (which doesn't happen often, but it's often
32 6825a95bSMasahiro Yamada# unavoidable when linking the built-in.o targets which finally
33 6825a95bSMasahiro Yamada# turn into vmlinux), we will call a sub make in that other dir, and
34 6825a95bSMasahiro Yamada# after that we are sure that everything which is in that other dir
35 6825a95bSMasahiro Yamada# is now up to date.
36 6825a95bSMasahiro Yamada#
37 6825a95bSMasahiro Yamada# The only cases where we need to modify files which have global
38 6825a95bSMasahiro Yamada# effects are thus separated out and done before the recursive
39 6825a95bSMasahiro Yamada# descending is started. They are now explicitly listed as the
40 6825a95bSMasahiro Yamada# prepare rule.

43 ffe29ebcSMasahiro Yamada# ---------------------------------------------------------------------------
44 ffe29ebcSMasahiro Yamada#
45 ffe29ebcSMasahiro Yamada# Normally, we echo the whole command before executing it. By making
46 ffe29ebcSMasahiro Yamada# that echo $($(quiet)$(cmd)), we now have the possibility to set
47 ffe29ebcSMasahiro Yamada# $(quiet) to choose other forms of output instead, e.g.
48 ffe29ebcSMasahiro Yamada#

51 ffe29ebcSMasahiro Yamada#
52 ffe29ebcSMasahiro Yamada# If $(quiet) is empty, the whole command will be printed.

54 ffe29ebcSMasahiro Yamada# If it is set to "silent_", nothing will be printed at all, since
