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

64 | # Beautify output |
65 | # --------------------------------------------------------------------------- | |
66 | # | |
67 | # Normally, we echo the whole command before executing it. By making | |
68 | # that echo $($(quiet)$(cmd)), we now have the possibility to set | |
69 | # $(quiet) to choose other forms of output instead, e.g. | |
70 | # | |
71 | # quiet_cmd_cc_o_c = Compiling $(RELDIR)/$@ | |
72 | # cmd_cc_o_c = $(CC) $(c_flags) -c -o $@ $< | |
73 | # | |
74 | # If $(quiet) is empty, the whole command will be printed. | |
75 | # If it is set to "quiet_", only the short version will be printed. | |
76 | # If it is set to "silent_", nothing will be printed at all, since | |
77 | # the variable $(silent_cmd_cc_o_c) doesn't exist. | |
78 | # | |
79 | # A simple variant is to prefix commands with $(Q) - that's useful | |
80 | # for commands that shall be hidden in non-verbose mode. | |
81 | # | |
82 | # $(Q)ln $@ :< | |
83 | # | |
84 | # If KBUILD_VERBOSE equals 0 then the above command will be hidden. | |
85 | # If KBUILD_VERBOSE equals 1 then the above command is displayed. | |
