  29# 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.
  44
  45# Beautify output
  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#
  65# If KBUILD_VERBOSE equals 0 then the above command will be hidden.
  66# If KBUILD_VERBOSE equals 1 then the above command is displayed.
