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):

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
