	(extract_cie_info): Handle S flag in augmentation string.
	(execute_cfa_program): If context->signal_frame, execute also
	fs->pc == context->ra instructions.
	(uw_frame_state_for): If context->signal_frame, don't subtract one
	from context->ra to find FDE.
	(uw_update_context_1): Set context->signal_frame to
	fs->signal_frame.
	(_Unwind_GetIPInfo): New function.
	* unwind-dw2.h (_Unwind_FrameState): Add signal_frame field.
	* unwind-c.c (PERSONALITY_FUNCTION): Use _Unwind_GetIPInfo instead
	of _Unwind_GetIP.
	* unwind-sjlj.c (_Unwind_GetIPInfo): New function.
	* unwind-generic.h (_Unwind_GetIPInfo): New prototype.
	* unwind-compat.c (_Unwind_GetIPInfo): New function.
	* libgcc-std.ver (_Unwind_GetIPInfo): Export @@GCC_4.2.0.
	* config/ia64/unwind-ia64.c (_Unwind_GetIPInfo): New function.
	* config/arm/unwind-arm.h (_Unwind_GetIPInfo): Define.
	* config/i386/linux-unwind.h (x86_fallback_frame_state,
