| 32 | # We are using a recursive build, so we need to do a little thinking |
| 33 | # to get the ordering right. |
| 34 | # |
| 35 | # Most importantly: sub-Makefiles should only ever modify files in |
| 36 | # their own directory. If in some directory we have a dependency on |
| 37 | # a file in another dir (which doesn't happen often, but it's often |
| 38 | # unavoidable when linking the built-in.o targets which finally |
| 39 | # turn into vmlinux), we will call a sub make in that other dir, and |
| 40 | # after that we are sure that everything which is in that other dir |
| 41 | # is now up to date. |
| 42 | # |
| 43 | # The only cases where we need to modify files which have global |
| 44 | # effects are thus separated out and done before the recursive |
| 45 | # descending is started. They are now explicitly listed as the |
| 46 | # prepare rule. |
