# NOTES ON AMIGA VERSION:
#   Amiga modifications by Kjetil Jacobsen / Ymir's Thoughts
#   The distributed binaries were compiled with gcc2.3.3, using gmake and flex.
#   You need ixemul v39.47 (or later) to run SPIM.
#   This Amiga version is based on spim/xspim version 5.4
#
# To make spim, type:
#
#   make spim
#
# To make xpsim, type:
#
#   make xspim
#

#
# To make cl-spim (cycle level SPIM simulator), type:
#
#   make cl-spim
#
# To make cl-xpsim, type:
#
#   make cl-xspim
#

# This is amiga specific, so it's got an unique vesion number.
