Masahiro Yamada6825a952014-02-04 17:24:28 +090051# We are using a recursive build, so we need to do a little thinking
52# to get the ordering right.
53#
54# Most importantly: sub-Makefiles should only ever modify files in
55# their own directory. If in some directory we have a dependency on
56# a file in another dir (which doesn't happen often, but it's often
57# unavoidable when linking the built-in.o targets which finally
58# turn into vmlinux), we will call a sub make in that other dir, and
59# after that we are sure that everything which is in that other dir
60# is now up to date.
61#
62# The only cases where we need to modify files which have global
63# effects are thus separated out and done before the recursive
64# descending is started. They are now explicitly listed as the
65# prepare rule.

68# ---------------------------------------------------------------------------
69#
70# Normally, we echo the whole command before executing it. By making
71# that echo $($(quiet)$(cmd)), we now have the possibility to set
72# $(quiet) to choose other forms of output instead, e.g.
73#
74# quiet_cmd_cc_o_c = Compiling $(RELDIR)/$@
75# cmd_cc_o_c = $(CC) $(c_flags) -c -o $@ $<
76#
77# If $(quiet) is empty, the whole command will be printed.
78# If it is set to "quiet_", only the short version will be printed.
79# If it is set to "silent_", nothing will be printed at all, since
80# the variable $(silent_cmd_cc_o_c) doesn't exist.
81#
82# A simple variant is to prefix commands with $(Q) - that's useful
83# for commands that shall be hidden in non-verbose mode.
84#
85# $(Q)ln $@ :<
86#
