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. | |
