This finally removes the Y constraint from the vector patterns while
folding some of them using a code iterator.
gcc/ChangeLog:
2016-03-01 Andreas Krebbel <krebbel@linux.vnet.ibm.com>
* config/s390/subst.md (DSI_VI): New mode iterator.
("addr_style_op_subst"): Use DSI_VI instead of DSI.
* config/s390/vector.md ("vec_set<mode>"): Move expander before
the insn definition.
("*vec_set<mode>"): Change predicate and add alternative to
support only either register or const_int operands as element
selector.
("*vec_set<mode>_plus"): New pattern to support reg + const_int
operands.
("vec_extract<mode>"): New expander.
("*vec_extract<mode>"): New insn definition supporting reg and
const_int element selectors.
("*vec_extract<mode>_plus"): New insn definition supporting
reg+const_int element selectors.
("rotl<mode>3", "ashl<mode>3", "ashr<mode>3"): Merge into the

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.
