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

217 kx #
217 kx # quiet_cmd_cc_o_c = Compiling $(RELDIR)/$@
217 kx # cmd_cc_o_c = $(CC) $(c_flags) -c -o $@ $<
217 kx #
217 kx # If $(quiet) is empty, the whole command will be printed.
217 kx # If it is set to "quiet_", only the short version will be printed.
