| # 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.
