Add VEC_SERIES_EXPR and associated optab
Similarly to the VEC_DUPLICATE_EXPR, this patch adds a tree code equivalent of the VEC_SERIES rtx code: VEC_SERIES_EXPR. 2017-12-16 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * doc/generic.texi (VEC_SERIES_EXPR): Document. * doc/md.texi (vec_series@var{m}): Document. * tree.def (VEC_SERIES_EXPR): New tree code. * tree.h (build_vec_series): Declare. * tree.c (build_vec_series): New function. * cfgexpand.c (expand_debug_expr): Handle VEC_SERIES_EXPR. * tree-pretty-print.c (dump_generic_node): Likewise. * gimple-pretty-print.c (dump_binary_rhs): Likewise. * tree-inline.c (estimate_operator_cost): Likewise. * expr.c (expand_expr_real_2): Likewise. * optabs-tree.c (optab_for_tree_code): Likewise. * tree-cfg.c (verify_gimple_assign_binary): Likewise. * fold-const.c (const_binop): Fold VEC_SERIES_EXPRs of constants. * expmed.c (make_tree): Handle VEC_SERIES. * optabs.def (vec_series_optab): New optab. * optabs.h (expand_vec_series_expr): Declare. * optabs.c (expand_vec_series_expr): New function. * tree-vect-generic.c (expand_vector_operations_1): Check that the operands also have vector type.
