# Makefile for NetBSD

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

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