- # 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.
