* config/arm/arm.md (maddhidi4): Remove '*' from name.
* expr.c (expand_expr_real_2): Use find_widening_optab_handler.
* optabs.c (find_widening_optab_handler_and_mode): New function.
(expand_widen_pattern_expr): Use find_widening_optab_handler.
(expand_binop_directly): Likewise.
(expand_binop): Likewise.
* optabs.h (find_widening_optab_handler): New macro define.
(find_widening_optab_handler_and_mode): New prototype.
* tree-cfg.c (verify_gimple_assign_binary): Adjust WIDEN_MULT_EXPR
type precision rules.
(verify_gimple_assign_ternary): Likewise for WIDEN_MULT_PLUS_EXPR.
* tree-ssa-math-opts.c (build_and_insert_cast): New function.
(is_widening_mult_rhs_p): Allow widening by more than one mode.
Explicitly disallow mis-matched input types.
(convert_mult_to_widen): Use find_widening_optab_handler, and cast
input types to fit the new handler.
