#    Description:
#      This file is the host make file for the International
#      Components for Unicode (ICU) library.
#

# To cross-compile, ICU needs to be bootstrapped for whatever the
# native build host is. In our environment, that's the simulator.  At
# some point in the future, we should tease apart truly building for
# the simulator and just building host-native stuff to support a build
# target.

#TODO QUESTION what is this?  diamondsim // diamond3sim?
