  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.

  46 # ---------------------------------------------------------------------------

  48 # Normally, we echo the whole command before executing it. By making
  49 # that echo $($(quiet)$(cmd)), we now have the possibility to set

  51 #

  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.
