(leaf_reg_backmap): Delete.
(sparc_flat_compute_frame_size): Renamed from sparc_frw_compute_frame_size. All callers changed. (sparc_flat_save_restore): Likewise. (sparc_flat_output_function_prologue): Likewise. Delete decl of call_used_regs. Delete reference to frame_base_name, use frame pointer explicitly. Print prologue end marker. (sparc_flat_output_function_epilogue): Likewise (renaming). Delete decls of asm_out_data_file, asm_out_file, call_used_regs. Print epilogue start marker. (sparc_flat_epilogue_delay_slots): Likewise (renaming). (sparc_flat_eligible_for_epilogue_delay): Likewise. From-SVN: r7258
