26 # We are using a recursive build, so we need to do a little thinking
27 # to get the ordering right.
29 # Most importantly: sub-Makefiles should only ever modify files in
30 # their own directory. If in some directory we have a dependency on
31 # a file in another dir (which doesn't happen often, but it's often
32 # unavoidable when linking the built-in.o targets which finally
33 # turn into vmlinux), we will call a sub make in that other dir, and
34 # after that we are sure that everything which is in that other dir
37 # The only cases where we need to modify files which have global
38 # effects are thus separated out and done before the recursive
39 # descending is started. They are now explicitly listed as the
43 # ---------------------------------------------------------------------------
45 # Normally, we echo the whole command before executing it. By making
46 # that echo $($(quiet)$(cmd)), we now have the possibility to set
47 # $(quiet) to choose other forms of output instead, e.g.
49 # quiet_cmd_cc_o_c = Compiling $(RELDIR)/$@
50 # cmd_cc_o_c = $(CC) $(c_flags) -c -o $@ $<
52 # If $(quiet) is empty, the whole command will be printed.
53 # If it is set to "quiet_", only the short version will be printed.
54 # If it is set to "silent_", nothing will be printed at all, since
55 # the variable $(silent_cmd_cc_o_c) doesn't exist.
57 # A simple variant is to prefix commands with $(Q) - that's useful
58 # for commands that shall be hidden in non-verbose mode.
62 # If KBUILD_VERBOSE equals 0 then the above command will be hidden.
63 # If KBUILD_VERBOSE equals 1 then the above command is displayed.
