* optabs.def (vcondeq_optab, vec_cmpeq_optab): New optabs.
* optabs.c (expand_vec_cond_expr): For comparison codes
EQ_EXPR and NE_EXPR, attempt vcondeq_optab as fallback.
(expand_vec_cmp_expr): For comparison codes
EQ_EXPR and NE_EXPR, attempt vec_cmpeq_optab as fallback.
* optabs-tree.h (expand_vec_cmp_expr_p, expand_vec_cond_expr_p):
Add enum tree_code argument.
* optabs-query.h (get_vec_cmp_eq_icode, get_vcond_eq_icode): New
inline functions.

CODE EQ_EXPR or NE_EXPR, attempt to use vec_cmpeq_optab as
fallback.
(expand_vec_cond_expr_p): Add CODE argument. For CODE EQ_EXPR or
NE_EXPR, attempt to use vcondeq_optab as fallback.
* tree-vect-generic.c (expand_vector_comparison,
expand_vector_divmod, expand_vector_condition): Adjust
expand_vec_cmp_expr_p and expand_vec_cond_expr_p callers.

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.
