ZERO_EXTRACT since the recognizer function forces them to match the

(const_ok_for_arm): Add fast return for 0 or just a single non-zero bit.

(arm_rtx_costs): New function.
(reg_or_int_operand): New function.
(shift_operator): Accept ROTATERT.
(multi_register_push): New function.
(shift_op): Don't abort if a constant is outside the acceptable range, but
convert the whole shift expression into something legal.  If the shift is
zero, then return NULL.
(output_return_instruction): Output a call to abort if the function is
volatile.
(arm_volatile_func): New function.
(get_prologue_size): Remove all adjustments for insns that are now output as
rtx.

a few comments.
(output_func_epilogue): Output a call to abort if a volatile function tries
to return.
(emit_multi_reg_push): New function.
(arm_expand_prologue): New function.  Don't bother to push call-saved regs
if we will never return.
(arm_print_operand, case 'S'): If shift_op returns NULL, then no shift is
required.

(DEFAULT_SIGNED_CHAR): Use unsigned unless already defined.
(RTX_COSTS): Call arm_rtx_costs.
(ADDRESS_COST): Since most operations have the same rtx cost, make the
more complex addresses cheaper.
(PREDICATE_CODES): Add ROTATERT to shift_operator; and new predicates for
reg_or_int_operand and multi_register_push.
(DBX_CONTIN_LENGTH): Only define if not already done.

(reload_outdf): Rewrite to expand to the two required insns.
(matcher for movdf): Remove alternative that used scratch register for
storing.
(movxf): rewrite as expand.
