  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.
  38. # Beautify output
  39. # ---------------------------------------------------------------------------
  40. #
  41. # Normally, we echo the whole command before executing it. By making
  42. # that echo $($(quiet)$(cmd)), we now have the possibility to set
  43. # $(quiet) to choose other forms of output instead, e.g.
  44. #
  45. # quiet_cmd_cc_o_c = Compiling $(RELDIR)/$@
  46. # cmd_cc_o_c = $(CC) $(c_flags) -c -o $@ $<
  47. #
  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.
  52. #
  53. # A simple variant is to prefix commands with $(Q) - that's useful
  54. # for commands that shall be hidden in non-verbose mode.
  55. #
  56. # $(Q)ln $@ :<
  57. #
  58. # If KBUILD_VERBOSE equals 0 then the above command will be hidden.
  59. # If KBUILD_VERBOSE equals 1 then the above command is displayed.
  60. #
  61. # To put more focus on warnings, be less verbose as default
  62. # Use 'make V=1' to see the full commands
