3# Makefile for NetBSD
4#
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/sparc64/conf/``machineid''
9# after which you should do
10#	config machineid
11# Machine generic makefile changes should be made in
12#	/sys/arch/sparc64/conf/Makefile.sparc64
13# after which config should be rerun for all machines of that type.
14
15# Always use sparc64 as the MACHINE_ARCH, so we select the correct
16# toolchain (i.e. need v9 instruction support in the assembler, etc.)
17# 32-bit vs. 64-bit will be selected based on compiler/assember options.
