S/390: Enable wraparound in s390_contiguous_bitmask_p.
gcc/ChangeLog:
2016-09-23 Dominik Vogt <vogt@linux.vnet.ibm.com>
* config/s390/predicates.md ("contiguous_bitmask_operand"): Adapt to new
interface of s390_contiguous_bitmask_p.
("contiguous_bitmask_nowrap_operand"): New predicate.
* ("*anddi3_cc", "*anddi3_cconly", "*anddi3"): Replace NxxDq with NxxDw.
* config/s390/constraints.md ("NxxDw", "NxxSq"): Adapt to new interface
of s390_contiguous_bitmask_p.
* ("NxxDw"): Rename NxxDq constraint to NxxDw.
("NxxSw"): New constraint.
* config/s390/s390.md ("*andsi3_zarch"): Enable bitmask wraparound.
* config/s390/s390-protos.h (s390_contiguous_bitmask_p): Updated
interface.
(s390_contiguous_bitmask_nowrap_p): Export.
* config/s390/s390.c (s390_contiguous_bitmask_nowrap_p): New name of
former s390_contiguous_bitmask_p.
(s390_contiguous_bitmask_p): Use s390_contiguous_bitmask_nowrap_p to
detect contiguous bit ranges with wraparound. Change signature to
return START and END position instead of POS and LENGTH.
(s390_contiguous_bitmask_vector_p): Remove extra code for continous bit
ranges with wraparound.
(s390_extzv_shift_ok): Use s390_contiguous_bitmask_nowrap_p.
(s390_contiguous_bitmask_vector_p,s390_extzv_shift_ok,print_operand):
Adapt to new signature of s390_contiguous_bitmask_p.
