newsuif - convert an old SUIF file to the current SUIF format
newsuif infile outfile
After converting a SUIF file to the old format with the oldsuif program and running some passes from the old SUIF system, you need to run the newsuif program to convert back to the current SUIF file format. If the file has been modified extensively, newsuif may have trouble recovering some of the information that is missing from the old SUIF format, but so far that has not been a problem. Note that newsuif will not handle arbitrary old SUIF files, but only those that were originally created by oldsuif.
