	gcc            : ChangeLog reg-stack.c 

Log message:
	* reg-stack.c (compensate_edge): Remove original prototype.
	(propagate_stack): New function to copy the stack layout
	at the start of a basic block from the layout at the end of
	one of its predecessors.
	(compensate_edge): Assume that both source and destination
	blocks have already had their stack layouts defined.
	(compensate_edges): Traverse all non-entry edges in the CFG
	and call compensate_edge on each in turn.
	(convert_regs_1): Change return type to void.  Call
	propagate_stack instead of compensate_edge.
	(convert_regs_2): Change return type to void.  Update call
	to convert_regs_1 to ignore the (now void) return value.
	(convert_regs): Update calls to convert_regs_2 to ignore
	the (now void) return value.  After all the basic blocks have
	been processed, call compensate_edges to actually emit new
	insns.
	(reg_to_stack): Initialize the aux info for each basic block
	with FOR_EACH_BB instead of which FOR_EACH_BB_REVERSE.
