# 	$NetBSD: Makefile.sparc64,v 1.40 2001/10/24 18:49:39 thorpej 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/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.

# Always use sparc64 as the MACHINE_ARCH, so we select the correct
# toolchain (i.e. need v9 instruction support in the assembler, etc.)
# 32-bit vs. 64-bit will be selected based on compiler/assember options.
