* config/rs6000/rs6000.c (emit_allocate_stack): Add copy_r11
parameter. Copy stack_reg to r11 where appropriate.
(no_global_regs_above): Add gpr parameter.
(rs6000_stack_info): Only add padding for SPE save area if we
are saving SPE GPRs and CR.
(saveres_routine_syms): New variable.
(FIRST_SAVRES_REGISTER, LAST_SAVRES_REGISTER, N_SAVRES_REGISTERS):
Define.
(rs6000_savres_routine_sym): New function.
(rs6000_emit_stack_reset, rs6000_restore_saved_cr): New functions,
split out of...
(rs6000_emit_epilogue): ...here. Use rs6000_use_multiple_p and
rs6000_savres_strategy. Restore GPRs out-of-line if appropriate.
Tweak FPR out-of-line saving.
(rs6000_make_savres_rtx): New function.
(rs6000_use_multiple_p): New function.
(rs6000_savres_strategy): New function.
(rs6000_emit_prologue): Use rs6000_savres_strategy. Save GPRs
out-of-line if appropriate.
* config/rs6000/sysv4.h (FP_SAVE_INLINE): Save FPRs out-of-line
if we are optimizing for size.
(GP_SAVE_INLINE): Define.
(SAVE_FP_SUFFIX, RESTORE_FP_SUFFIX): Only use _l on 64-bit targets.
* config/rs6000/darwin.h (GP_SAVE_INLINE): Define.
* config/rs6000/aix.h (GP_SAVE_INLINE): Define.
* config/rs6000/rs6000.md (*save_gpregs_<mode>): New insn.
(*save_fpregs_<mode>): Add use of r11.
(*restore_gpregs_<mode>): New insn.
(*return_and_restore_gpregs_<mode>): New insn.
(*return_and_restore_fpregs_<mode>): Adjust to clobber LR and
use r11.
* config/rs6000/spe.md (*save_gpregs_spe): New insn.
(*restore_gpregs_spe): New insn.
(*return_and_restore_gpregs_spe): New insn.
* config/rs6000/predicates.md (save_world_operation): Fix check.
