15 # This makefile is constructed from a machine description:
16 # config machineid
17 # Most changes should be made in the machine description
18 # /sys/arch/sparc64/conf/``machineid''
19 # after which you should do
20 # config machineid
21 # Machine generic makefile changes should be made in
22 # /sys/arch/sparc64/conf/Makefile.sparc64
23 # after which config should be rerun for all machines of that type.
24 #
25 # To specify debugging, add the config line: makeoptions DEBUG="-g"
26 # A better way is to specify -g only for a few files.
27 #
28 # makeoptions DEBUGLIST="uvm* trap if_*"

30 # Default to 32-bit. Set the MACHINE_ARCH accordingly.
31 #
32 # You must also be using the correct toolchain or the kernel build
33 # will fail.
