We also probably have to set SSA_NAME_DEF_STMT to NULL in bsi_remove in order to be sure that an SSA name with no uses isn't actually associated with a stmt any more (you can have valid defs with no uses). It is set when the SSA_NAME is created, but I don't think that field ever gets cleared anywhere else. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23940
