48 # We are using a recursive build, so we need to do a little thinking
49 # to get the ordering right.
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
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
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.
71 # quiet_cmd_cc_o_c = Compiling $(RELDIR)/$@

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.
