Add MULT_HIGHPART_EXPR
* tree.def (MULT_HIGHPART_EXPR): New. * cfgexpand.c (expand_debug_expr): Ignore it. * expr.c (expand_expr_real_2): Handle it. * fold-const.c (int_const_binop_1): Likewise. * optabs.c (optab_for_tree_code): Likewise. * tree-cfg.c (verify_gimple_assign_binary): Likewise. * tree-inline.c (estimate_operator_cost): Likewise. * tree-pretty-print.c (dump_generic_node): Likewise. (op_code_prio, op_symbol_code): Likewise. * tree.c (commutative_tree_code): Likewise. Also handle WIDEN_MULT_EXPR, VEC_WIDEN_MULT_HI_EXPR, VEC_WIDEN_MULT_LO_EXPR. From-SVN: r189027
