  23. # We are using a recursive build, so we need to do a little thinking
  24. # to get the ordering right.
  25. #
  26. # Most importantly: sub-Makefiles should only ever modify files in
  27. # their own directory. If in some directory we have a dependency on
  28. # a file in another dir (which doesn't happen often, but it's often
  29. # unavoidable when linking the built-in.o targets which finally
  30. # turn into vmlinux), we will call a sub make in that other dir, and
  31. # after that we are sure that everything which is in that other dir
  32. # is now up to date.
  33. #
  34. # The only cases where we need to modify files which have global
  35. # effects are thus separated out and done before the recursive
  36. # descending is started. They are now explicitly listed as the
  37. # prepare rule.

  46. # cmd_cc_o_c = $(CC) $(c_flags) -c -o $@ $<

  48. # If $(quiet) is empty, the whole command will be printed.
  49. # If it is set to "quiet_", only the short version will be printed.
  50. # If it is set to "silent_", nothing will be printed at all, since
  51. # the variable $(silent_cmd_cc_o_c) doesn't exist.
