expr.c (expand_expr_real_2): Use widening_optab_handler.
2011-08-19 Andrew Stubbs <ams@codesourcery.com>
gcc/
* expr.c (expand_expr_real_2): Use widening_optab_handler.
* genopinit.c (optabs): Use set_widening_optab_handler for $N.
(gen_insn): $N now means $a must be wider than $b, not consecutive.
* optabs.c (widened_mode): New function.
(expand_widen_pattern_expr): Use widening_optab_handler.
(expand_binop_directly): Likewise.
(expand_binop): Likewise.
* optabs.h (widening_optab_handlers): New struct.
(optab_d): New member, 'widening'.
(widening_optab_handler): New function.
(set_widening_optab_handler): New function.
* tree-ssa-math-opts.c (convert_mult_to_widen): Use
widening_optab_handler.
(convert_plusminus_to_widen): Likewise.
