--- Comment #17 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Author: jakub Date: Tue Oct 25 16:26:12 2016 New Revision: 241525 URL: https://gcc.gnu.org/viewcvs?rev=241525&root=gcc&view=rev Log: PR target/78102 * 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. * optabs-tree.c (expand_vec_cmp_expr_p): Add CODE argument. For 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. * tree-vect-stmts.c (vectorizable_condition, vectorizable_comparison): Likewise. * tree-vect-patterns.c (vect_recog_mixed_size_cond_pattern, check_bool_pattern, search_type_for_mask_1): Likewise. * expr.c (do_store_flag): Likewise. * doc/md.texi (@code{vec_cmpeq@var{m}@var{n}}, @code{vcondeq@var{m}@var{n}}): Document. * config/i386/sse.md (vec_cmpeqv2div2di, vcondeq<VI8F_128:mode>v2di): New expanders. testsuite/ * gcc.target/i386/pr78102.c: New test.
