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.
