SUIF does not have many code generators. SUIF is not supported software. It is distributed without warranty. We will do what we can to help you with problems, but in the end you're on your own. The SUIF system is now distributed in several different pieces.
Some pieces are more stable and others less so.
For example, the basic parallelization system is separated from the base SUIF system, so those who are interested in only the basic compiler infrastructure don't have to deal with all the overhead and greater instability of the parallelizer. This allows frequently changing releases of the more experimental parts without affecting the continuity of the more stable parts of the system. It also allows researchers at other sites to maintain and release their own pieces without having to coordinate with Stanford. The base SUIF system, required before any of the other packages can be used. Signed pgp certificates for all packages are also available in the same directory with the suffix .asc appended to the compressed tar file name.
