Masahiro Yamada6825a952014-02-04 17:24:28 +090031# We are using a recursive build, so we need to do a little thinking
32# to get the ordering right.
33#
34# Most importantly: sub-Makefiles should only ever modify files in
35# their own directory. If in some directory we have a dependency on
36# a file in another dir (which doesn't happen often, but it's often
37# unavoidable when linking the built-in.o targets which finally
38# turn into vmlinux), we will call a sub make in that other dir, and
39# after that we are sure that everything which is in that other dir
40# is now up to date.
41#
42# The only cases where we need to modify files which have global
43# effects are thus separated out and done before the recursive
44# descending is started. They are now explicitly listed as the
45# prepare rule.

48# ---------------------------------------------------------------------------
49#
50# Normally, we echo the whole command before executing it. By making
51# that echo $($(quiet)$(cmd)), we now have the possibility to set
52# $(quiet) to choose other forms of output instead, e.g.
53#
54# quiet_cmd_cc_o_c = Compiling $(RELDIR)/$@
55# cmd_cc_o_c = $(CC) $(c_flags) -c -o $@ $<
56#
57# If $(quiet) is empty, the whole command will be printed.
58# If it is set to "quiet_", only the short version will be printed.
59# If it is set to "silent_", nothing will be printed at all, since
60# the variable $(silent_cmd_cc_o_c) doesn't exist.
61#
62# A simple variant is to prefix commands with $(Q) - that's useful
63# for commands that shall be hidden in non-verbose mode.
64#
65# $(Q)ln $@ :<
66#
67# If KBUILD_VERBOSE equals 0 then the above command will be hidden.
