5 # This makefile is constructed from a machine description:
6 # config machineid
7 # Most changes should be made in the machine description
8 # /sys/arch/powerpc/conf/``machineid''
9 # after which you should do
10 # config machineid
11 # Machine generic makefile changes should be made in
12 # /sys/arch/powerpc/conf/Makefile.powerpc
13 # after which config should be rerun for all machines of that type.
14 #
15 # To specify debugging, add the config line: makeoptions DEBUG="-g"
16 # A better way is to specify -g only for a few files.
17 #
18 # makeoptions DEBUGLIST="uvm* trap if_*"
