Masahiro Yamada6825a952014-02-04 17:24:28 +090026# We are using a recursive build, so we need to do a little thinking
27# to get the ordering right.
28#
29# Most importantly: sub-Makefiles should only ever modify files in
30# their own directory. If in some directory we have a dependency on
31# a file in another dir (which doesn't happen often, but it's often
32# unavoidable when linking the built-in.o targets which finally
33# turn into vmlinux), we will call a sub make in that other dir, and
34# after that we are sure that everything which is in that other dir
35# is now up to date.
36#
37# The only cases where we need to modify files which have global
38# effects are thus separated out and done before the recursive
39# descending is started. They are now explicitly listed as the
40# prepare rule.

Masahiro Yamadaffe29eb2014-10-30 11:06:11 +090042# Beautify output
43# ---------------------------------------------------------------------------
44#
45# Normally, we echo the whole command before executing it. By making
46# that echo $($(quiet)$(cmd)), we now have the possibility to set
47# $(quiet) to choose other forms of output instead, e.g.
48#
49# quiet_cmd_cc_o_c = Compiling $(RELDIR)/$@
50# cmd_cc_o_c = $(CC) $(c_flags) -c -o $@ $<
51#
52# If $(quiet) is empty, the whole command will be printed.
53# If it is set to "quiet_", only the short version will be printed.
54# If it is set to "silent_", nothing will be printed at all, since
55# the variable $(silent_cmd_cc_o_c) doesn't exist.
56#
57# A simple variant is to prefix commands with $(Q) - that's useful
58# for commands that shall be hidden in non-verbose mode.
59#
60# $(Q)ln $@ :<
61#
62# If KBUILD_VERBOSE equals 0 then the above command will be hidden.
63# If KBUILD_VERBOSE equals 1 then the above command is displayed.
