Masahiro Yamada0d68fb12014-02-04 17:24:28 +090029# We are using a recursive build, so we need to do a little thinking
30# to get the ordering right.
31#
32# Most importantly: sub-Makefiles should only ever modify files in
33# their own directory. If in some directory we have a dependency on
34# a file in another dir (which doesn't happen often, but it's often
35# unavoidable when linking the built-in.o targets which finally
36# turn into vmlinux), we will call a sub make in that other dir, and
37# after that we are sure that everything which is in that other dir
38# is now up to date.
39#
40# The only cases where we need to modify files which have global
41# effects are thus separated out and done before the recursive
42# descending is started. They are now explicitly listed as the
43# prepare rule.

46# ---------------------------------------------------------------------------
47#
48# Normally, we echo the whole command before executing it. By making
49# that echo $($(quiet)$(cmd)), we now have the possibility to set
50# $(quiet) to choose other forms of output instead, e.g.
51#
52# quiet_cmd_cc_o_c = Compiling $(RELDIR)/$@
53# cmd_cc_o_c = $(CC) $(c_flags) -c -o $@ $<
54#
55# If $(quiet) is empty, the whole command will be printed.
56# If it is set to "quiet_", only the short version will be printed.
57# If it is set to "silent_", nothing will be printed at all, since
58# the variable $(silent_cmd_cc_o_c) doesn't exist.
59#
60# A simple variant is to prefix commands with $(Q) - that's useful
61# for commands that shall be hidden in non-verbose mode.
62#
63# $(Q)ln $@ :<
64#
