	PR 15813
	* dwarf2out.c (reg_save): Output DW_CFA_same_value when a
	register is saved in itself.
	(initial_return_save): If the return address is a register,
	it's already there, don't bother to mention it in the CFI.
	(struct queued_reg_save): Add field saved_reg.
	(struct reg_saved_in_data): New.
	(regs_saved_in_regs): New.
	(num_regs_saved_in_regs): New.
	(queue_reg_save): Add extra parameter to specify register saved
	in register.  Remove duplicate entries from queue.  Add comment
	for function.
	(flush_queued_reg_saves): Handle registers saved in registers.
	Update regs_saved_in_regs.  Add comment for function.
	(clobbers_queued_reg_save): Add comment for function.  Allow
	for regs_saved_in_regs.
	(reg_saved_in): New.
	(dwarf2out_frame_debug_expr): Handle saving registers in other
	registers.
	(dwarf2out_frame_debug): Reset regs_saved_in_regs.
	* unwind-dw2.c (execute_cfa_program): Correct handling of
	DW_CFA_same_value.  Add FIXME comment about incorrect implementation
	of DW_CFA_restore_extended.
	* config/rs6000/rs6000.c (rs6000_emit_prologue): Let
	dwarf2out_frame_debug_expr see instructions that save registers
	in other registers or save those other registers in memory.
	
	* unwind-dw2.c (DWARF_FRAME_REGISTERS): Move to unwind-dw2.h.
	(_Unwind_FrameState): Likewise.
	* unwind-dw2.h: New.
	* Makefile.in (LIB2ADDEHDEP): Add unwind-dw2.h.
	* config/rs6000/darwin-fallback.c: New file.
	* config/rs6000/darwin.h (MD_FALLBACK_FRAME_STATE_FOR): Define.
