| | 31 | # We are using a recursive build, so we need to do a little thinking |
| | 32 | # to get the ordering right. |
| | 33 | # |
| | 34 | # Most importantly: sub-Makefiles should only ever modify files in |
| | 35 | # their own directory. If in some directory we have a dependency on |
| | 36 | # a file in another dir (which doesn't happen often, but it's often |
| | 37 | # unavoidable when linking the built-in.o targets which finally |
| | 38 | # turn into vmlinux), we will call a sub make in that other dir, and |
| | 39 | # after that we are sure that everything which is in that other dir |
| | 40 | # is now up to date. |
| | 41 | # |
| | 42 | # The only cases where we need to modify files which have global |
| | 43 | # effects are thus separated out and done before the recursive |
| | 44 | # descending is started. They are now explicitly listed as the |
| | 45 | # prepare rule. |
| | 46 | |
| | 47 | # Beautify output |
| | 48 | # --------------------------------------------------------------------------- |
| | 49 | # |
| | 50 | # Normally, we echo the whole command before executing it. By making |
| | 51 | # that echo $($(quiet)$(cmd)), we now have the possibility to set |
| | 52 | # $(quiet) to choose other forms of output instead, e.g. |
| | 53 | # |
| | 54 | # quiet_cmd_cc_o_c = Compiling $(RELDIR)/$@ |
| | 55 | # cmd_cc_o_c = $(CC) $(c_flags) -c -o $@ $< |
| | 56 | # |
| | 57 | # If $(quiet) is empty, the whole command will be printed. |
| | 58 | # If it is set to "quiet_", only the short version will be printed. |
| | 59 | # If it is set to "silent_", nothing will be printed at all, since |
| | 60 | # the variable $(silent_cmd_cc_o_c) doesn't exist. |
| | 61 | # |
