--- Comment #9 from alalaw01 at gcc dot gnu.org --- Author: alalaw01 Date: Mon Oct 27 14:04:43 2014 New Revision: 216736 URL: https://gcc.gnu.org/viewcvs?rev=216736&root=gcc&view=rev Log: [Vectorizer] Make REDUC_xxx_EXPR tree codes produce a scalar result PR tree-optimization/61114 * expr.c (expand_expr_real_2): For REDUC_{MIN,MAX,PLUS}_EXPR, add extract_bit_field around optab result. * fold-const.c (fold_unary_loc): For REDUC_{MIN,MAX,PLUS}_EXPR, produce scalar not vector. * tree-cfg.c (verify_gimple_assign_unary): Check result vs operand type for REDUC_{MIN,MAX,PLUS}_EXPR. * tree-vect-loop.c (vect_analyze_loop): Update comment. (vect_create_epilog_for_reduction): For direct vector reduction, use result of tree code directly without extract_bit_field. * tree.def (REDUC_MAX_EXPR, REDUC_MIN_EXPR, REDUC_PLUS_EXPR): Update comment.
