# We are using a recursive build, so we need to do a little thinking
|
# to get the ordering right.
|
#
|
# Most importantly: sub-Makefiles should only ever modify files in
|
# their own directory. If in some directory we have a dependency on
|
# a file in another dir (which doesn't happen often, but it's often
|
# unavoidable when linking the built-in.o targets which finally
|
# turn into vmlinux), we will call a sub make in that other dir, and
|
# after that we are sure that everything which is in that other dir
|
# is now up to date.
|
#
|
# The only cases where we need to modify files which have global
|
# effects are thus separated out and done before the recursive
|
# descending is started. They are now explicitly listed as the
|
# prepare rule.
|
|
# Beautify output
|
# ---------------------------------------------------------------------------
|
#
|
# Normally, we echo the whole command before executing it. By making
|
# that echo $($(quiet)$(cmd)), we now have the possibility to set
|
# $(quiet) to choose other forms of output instead, e.g.
|
#
|
# quiet_cmd_cc_o_c = Compiling $(RELDIR)/$@
|
# cmd_cc_o_c = $(CC) $(c_flags) -c -o $@ $<
|
#
|
# If $(quiet) is empty, the whole command will be printed.
|
# If it is set to "quiet_", only the short version will be printed.
|
# If it is set to "silent_", nothing will be printed at all, since
|
# the variable $(silent_cmd_cc_o_c) doesn't exist.
|

# for commands that shall be hidden in non-verbose mode.
