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

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

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