Masahiro Yamada0d68fb12014-02-04 17:24:28 +090048# We are using a recursive build, so we need to do a little thinking
49# to get the ordering right.
50#
51# Most importantly: sub-Makefiles should only ever modify files in
52# their own directory. If in some directory we have a dependency on
53# a file in another dir (which doesn't happen often, but it's often
54# unavoidable when linking the built-in.o targets which finally
55# turn into vmlinux), we will call a sub make in that other dir, and
56# after that we are sure that everything which is in that other dir
57# is now up to date.
58#
59# The only cases where we need to modify files which have global
60# effects are thus separated out and done before the recursive
61# descending is started. They are now explicitly listed as the
62# prepare rule.

65# ---------------------------------------------------------------------------

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