At the time this problem first occurred, the prototype was rtx *reg_known_value; Richard Henderson changed the prototype on March 24. There have been several problems appear on the hppa64 port and I was trying to deal with them sequently. PR 14829 ocurred just after, then the cgraph merge by Jan Hubicka on April 2 introduced another problem. I will check if Richard's change plus my fix for PR 14829 resolves the problem. If it does, I think Richard's change needs to be backported to 3.3 and 3.4. Dave -- J. David Anglin dave.anglin@nrc-cnrc.gc.ca National Research Council of Canada (613) 990-0752 (FAX: 952-6602)
