# $NetBSD: Makefile.powerpc,v 1.61 2018/09/22 12:24:03 rin Exp $
#
# Makefile for NetBSD
#
# This makefile is constructed from a machine description:
# config machineid
# Most changes should be made in the machine description
# /sys/arch/powerpc/conf/``machineid''
# after which you should do
# config machineid
# Machine generic makefile changes should be made in
# /sys/arch/powerpc/conf/Makefile.powerpc
# 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_*"
