Hi All, I seem to have broken the s390 bootstrap because I added a new parameter to the store_bit_field function to indicate whether the value the field of is being set is currently undefined. If it's undefined we use a subreg instead. In this case the value of false restores the old behavior. Ok for master? Thanks, Tamar gcc/ChangeLog: * config/s390/s390.cc (s390_expand_atomic): Pass false to store_bit_field to indicate that the value is not undefined.
