This is the Amiga implementation of the GNU superoptimizer version 2.3. There are four different binaries in this distribution named: gsoXX_YY XX = 00 program runs on all Amigas (even on machines with a plain 68000 processor) XX = 20 program only runs on Amigas with a 68020 or better processor YY = 00 the optimized code is for a 68000 processor YY = 20 the optimized code is for a 68020 processor or better To run this program you will need the ixemul.library (that is not a part of this distribution). Have fun Andre florath@jupiter.stochastik.rwth-aachen.de PS: In the file 'goal.def' are all functions listed that gso understands.
