	gcc/config/arm : arm.c arm.h 
	gcc/config/m68k: m68k.h 
	gcc/config/ns32k: ns32k.h 
	gcc/config/sparc: sparc.h 

Log message:
	Implement dwarf2 exception handling for the ARM.
	* config/arm/arm.h (INCOMING_RETURN_ADDR_RTX): Define.
	(DWARF_FRAME_RETURN_COLUMN): Define.
	* config/arm/arm.c (emit_multi_reg_push): Return rtx.  Attach
	REG_FRAME_RELATED_EXPR note.
	(emit_sfm): Likewise.
	(arm_expand_prologue): Set RTX_FRAME_RELATED_P on everything.
	* dwarf2out.c (reg_save): Handle saving a register to itself.
	(dwarf2out_frame_debug_expr): Handle an intermediate cfa reg.
	* except.c (eh_regs): Don't use the static chain reg if it's
	callee-saved.
	* frame.h (frame_state): Add cfa_saved field.
	* frame.c (execute_cfa_insn): Set it.
	* libgcc2.c (throw_helper): Don't adjust sp if it's restored in
	the epilogue.
	* function.c (ARG_POINTER_CFA_OFFSET): Default to FIRST_PARM_OFFSET.
	Now takes a parm.
	(instantiate_virtual_regs): Adjust.
	* tm.texi: Adjust.
	* config/m68k/m68k.h (ARG_POINTER_CFA_OFFSET): Don't define.
	* config/ns32k/ns32k.h (ARG_POINTER_CFA_OFFSET): Don't define.
	* config/sparc/sparc.h (ARG_POINTER_CFA_OFFSET): Take a parm.
	
	* dwarf2out.c (reg_number): Refer to FIRST_PSEUDO_REGISTER.
	(initial_return_save): Use DWARF_FRAME_REGNUM, not reg_number.
