	gcc            : ChangeLog 
	gcc/config/arm : arm-protos.h arm.c arm.h arm.md 

Log message:
	* arm.c (use_return_insn): New argument, SIBLING.  Support returning
	with a single instruction if the stack has been decremented by 4
	and we have a frame pointer.  Update all callers.
	(output_return_instruction): Likewise.
	(arm_output_epilogue): Change argument to SIBLING.  Calculate
	really_return from the new argument.  Update all callers.
	* arm.h (USE_RETURN_INSN): Pass NULL for the sibling.
	* arm.md (sibcall_epilogue): Call use_return_insn directly, and
	pass the sibling call.
	* arm-protos.h (use_return_insn, arm_output_epilogue): Update
	prototypes.
