53# to get the ordering right.
54#
55# Most importantly: sub-Makefiles should only ever modify files in
56# their own directory. If in some directory we have a dependency on
57# a file in another dir (which doesn't happen often, but it's often
58# unavoidable when linking the built-in.o targets which finally
59# turn into vmlinux), we will call a sub make in that other dir, and
60# after that we are sure that everything which is in that other dir
61# is now up to date.
62#
63# The only cases where we need to modify files which have global
64# effects are thus separated out and done before the recursive
65# descending is started. They are now explicitly listed as the
66# prepare rule.

71# Normally, we echo the whole command before executing it. By making
72# that echo $($(quiet)$(cmd)), we now have the possibility to set
73# $(quiet) to choose other forms of output instead, e.g.
74#
75# quiet_cmd_cc_o_c = Compiling $(RELDIR)/$@
76# cmd_cc_o_c = $(CC) $(c_flags) -c -o $@ $<
77#
78# If $(quiet) is empty, the whole command will be printed.
79# If it is set to "quiet_", only the short version will be printed.
80# If it is set to "silent_", nothing will be printed at all, since
81# the variable $(silent_cmd_cc_o_c) doesn't exist.
82#
83# A simple variant is to prefix commands with $(Q) - that's useful
84# for commands that shall be hidden in non-verbose mode.
