(output_move_double): If the dest is register pair and both regs are
used in src address, use ADDR to compute src address, not ADDD, which
throws away scaled index.

include tree.h
(const_ok_for_arm): Add fast return for 0 or just a single non-zero bit.
(const_ok_for_op): New function.
(arm_split_constant): New function.
(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.
(output_func_prologue): Remove all code that outputs instructions, just print
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.
From-SVN: r7537
(MODES_TIEABLE_P): All modes of the same class are tieable.
(CONST_OK_FOR_LETTER_P): Add 'M' for constants valid in a shift.
(FUNCTION_PROFILER): Don't call arm_increase_location.
(INITIAL_ELIMINATION_OFFSET): Call saved regs are no-longer pushed for
functions that don't return.
(LEGITIMIZE_ADDRESS): Push constants that will never be legitimate -- symbols
and labels -- into registers. Handle DImode better.
(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.
(PRINT_OPERAND_ADDRESS): Let arm_print operand output the ", " for shifts.
From-SVN: r7536
(STARTFILE_SPEC): Look in the correct places for start files.
(LIB_SPEC): Define.
(LINK_SPEC): Define.
(TARGET_WHEN_DEBUGGING): Delete.
(DEFAULT_SIGNED_CHAR): Set to unsigned.
(SIZE_TYPE, PTRDIFF_TYPE, TARGET_EDOM): Define.

Rewrite as expand patterns.
(rotlsi3): New expand.
(matchers, and split patterns for above): New.
(all patterns with shifts): Let arm_print_operand output the ", " before a
shift if it is needed.
(zero_extendqihi2): Delete.
(zero_extendqisi2): Expand to (and ...) if not memory.
(movsi): Call arm_split_constant to generate a constant.
(movqi): Only force a MEM into a register if not reloading.
(movsf, movdf): If loading a non-immediate floating point value, or loading
and floating point immediate into integer regs, push the constant straight
into the pool.
(movdf): Get rid of the scratch register.
(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.
(matcher for movxf): Recognize even when XFmode code is disabled, so that
prologue insns can be generated.
(Matcher for reversed conditional jump): Don't match if the mode of the
CC register is not reversible.
(prologue): New expand.
(matcher for multi_register_push insn): New.
From-SVN: r7533
(expand_binop): New variable next_methods; pass to most recursive calls when
trying to avoid libcalls.
Always check for a return value of zero in recursive calls.
(expand_float): Ensure TARGET has proper mode.
Pass OPTAB_LIB_WIDEN to expand_binop calls.
