acsawdey at gcc dot gnu.org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |acsawdey at gcc dot gnu.org --- Comment #1 from acsawdey at gcc dot gnu.org --- Looks to me like this configuration is not including rs6000-string.o. Can you see if this is fixed by adding rs6000-string.o to extra_objs in the *-*-darwin section of gcc/config.gcc?
