[PATCH][s390]: Fix the usage of store_bit_field in the backend.
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.
