  41. # We are using a recursive build, so we need to do a little thinking
  42. # to get the ordering right.
  43. #
  44. # Most importantly: sub-Makefiles should only ever modify files in
  45. # their own directory. If in some directory we have a dependency on
  46. # a file in another dir (which doesn't happen often, but it's often
  47. # unavoidable when linking the built-in.o targets which finally
  48. # turn into vmlinux), we will call a sub make in that other dir, and
  49. # after that we are sure that everything which is in that other dir
  50. # is now up to date.
  51. #
  52. # The only cases where we need to modify files which have global
  53. # effects are thus separated out and done before the recursive
  54. # descending is started. They are now explicitly listed as the
  55. # prepare rule.

  63. # quiet_cmd_cc_o_c = Compiling $(RELDIR)/$@
  64. # cmd_cc_o_c = $(CC) $(c_flags) -c -o $@ $<
