- # 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_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.
