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

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