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

  66. #
  67. # quiet_cmd_cc_o_c = Compiling $(RELDIR)/$@
  68. # cmd_cc_o_c = $(CC) $(c_flags) -c -o $@ $<

  72. # If it is set to "silent_", nothing will be printed at all, since
  73. # the variable $(silent_cmd_cc_o_c) doesn't exist.
