26 | # We are using a recursive build, so we need to do a little thinking |
27 | # to get the ordering right. |
28 | # |
29 | # Most importantly: sub-Makefiles should only ever modify files in |
30 | # their own directory. If in some directory we have a dependency on |
31 | # a file in another dir (which doesn't happen often, but it's often |
32 | # unavoidable when linking the built-in.o targets which finally |
33 | # turn into vmlinux), we will call a sub make in that other dir, and |
34 | # after that we are sure that everything which is in that other dir |
35 | # is now up to date. |
36 | # |
37 | # The only cases where we need to modify files which have global |
38 | # effects are thus separated out and done before the recursive |
39 | # descending is started. They are now explicitly listed as the |
40 | # prepare rule. |
41 | |
42 | # Beautify output |
43 | # --------------------------------------------------------------------------- |
44 | # |
45 | # Normally, we echo the whole command before executing it. By making |
46 | # that echo $($(quiet)$(cmd)), we now have the possibility to set |
47 | # $(quiet) to choose other forms of output instead, e.g. |
48 | # |
49 | # quiet_cmd_cc_o_c = Compiling $(RELDIR)/$@ |
50 | # cmd_cc_o_c = $(CC) $(c_flags) -c -o $@ $< |
51 | # |
52 | # If $(quiet) is empty, the whole command will be printed. |
53 | # If it is set to "quiet_", only the short version will be printed. |
54 | # If it is set to "silent_", nothing will be printed at all, since |
55 | # the variable $(silent_cmd_cc_o_c) doesn't exist. |
56 | # |

58 | # for commands that shall be hidden in non-verbose mode. |

61 | # |
62 | # If KBUILD_VERBOSE equals 0 then the above command will be hidden. |
