266825a95bSMasahiro Yamada# We are using a recursive build, so we need to do a little thinking
276825a95bSMasahiro Yamada# to get the ordering right.
286825a95bSMasahiro Yamada#
296825a95bSMasahiro Yamada# Most importantly: sub-Makefiles should only ever modify files in
306825a95bSMasahiro Yamada# their own directory. If in some directory we have a dependency on
316825a95bSMasahiro Yamada# a file in another dir (which doesn't happen often, but it's often
326825a95bSMasahiro Yamada# unavoidable when linking the built-in.o targets which finally
336825a95bSMasahiro Yamada# turn into vmlinux), we will call a sub make in that other dir, and
346825a95bSMasahiro Yamada# after that we are sure that everything which is in that other dir
356825a95bSMasahiro Yamada# is now up to date.
366825a95bSMasahiro Yamada#
376825a95bSMasahiro Yamada# The only cases where we need to modify files which have global
386825a95bSMasahiro Yamada# effects are thus separated out and done before the recursive
396825a95bSMasahiro Yamada# descending is started. They are now explicitly listed as the
406825a95bSMasahiro Yamada# prepare rule.

42ffe29ebcSMasahiro Yamada# Beautify output
43ffe29ebcSMasahiro Yamada# ---------------------------------------------------------------------------
44ffe29ebcSMasahiro Yamada#
45ffe29ebcSMasahiro Yamada# Normally, we echo the whole command before executing it. By making
46ffe29ebcSMasahiro Yamada# that echo $($(quiet)$(cmd)), we now have the possibility to set
47ffe29ebcSMasahiro Yamada# $(quiet) to choose other forms of output instead, e.g.
48ffe29ebcSMasahiro Yamada#
49ffe29ebcSMasahiro Yamada#         quiet_cmd_cc_o_c = Compiling $(RELDIR)/$@
50ffe29ebcSMasahiro Yamada#         cmd_cc_o_c       = $(CC) $(c_flags) -c -o $@ $<
51ffe29ebcSMasahiro Yamada#
52ffe29ebcSMasahiro Yamada# If $(quiet) is empty, the whole command will be printed.
53ffe29ebcSMasahiro Yamada# If it is set to "quiet_", only the short version will be printed.
54ffe29ebcSMasahiro Yamada# If it is set to "silent_", nothing will be printed at all, since
55ffe29ebcSMasahiro Yamada# the variable $(silent_cmd_cc_o_c) doesn't exist.
56ffe29ebcSMasahiro Yamada#
57ffe29ebcSMasahiro Yamada# A simple variant is to prefix commands with $(Q) - that's useful
58ffe29ebcSMasahiro Yamada# for commands that shall be hidden in non-verbose mode.
