#
# Toplevel makefile for the mipsi simulator for use with CSE 451.
#

#
# Running "make" will compile mipsi-orig, mipsi, and the sample
# user level applications.  You can also selectively make each target
# as described below.
#
# To make the default version of mipsi (the one that doesn't have VM),
# use "make mipsi-orig".
#
# To make the version of mipsi that you have to implement, 
# use "make mipsi".
#
# To make the default applications, use "make apps".
#
# To remove all object files and executables so that you can rebuild
# from scratch, use "make clean"
