regs.h (target_regs): Add x_hard_regs_of_mode...
gcc/
* regs.h (target_regs): Add x_hard_regs_of_mode, x_contains_reg_of_mode,
x_move_cost, x_may_move_in_cost, x_may_move_out_cost and
x_last_mode_for_init_move_cost.
(have_regs_of_mode, contains_reg_of_mode, move_cost)
(may_move_in_cost, may_move_out_cost): Redefine as macros.
* reginfo.c (have_regs_of_mode, contains_reg_of_mode, move_cost)
(may_move_in_cost, may_move_out_cost): Delete.
(last_mode_for_init_move_cost): Redefine as a macro.
