34 # Most importantly: sub-Makefiles should only ever modify files in
35 # their own directory. If in some directory we have a dependency on
36 # a file in another dir (which doesn't happen often, but it's often
37 # unavoidable when linking the built-in.o targets which finally
38 # turn into vmlinux), we will call a sub make in that other dir, and
39 # after that we are sure that everything which is in that other dir

43 # effects are thus separated out and done before the recursive
44 # descending is started. They are now explicitly listed as the

50 # Normally, we echo the whole command before executing it. By making
