	Simplified Guard

	Original rule:
	l6 -> l4 : a^0'=1, ret_returnone3^0'=1, tmp^0'=tmp^0, 0 == 0, cost: 1
	New rule:
	l6 -> l4 : a^0'=1, ret_returnone3^0'=1, tmp^0'=tmp^0, T, cost: 1
	
	Removed Trivial Updates

	Original rule:
	l6 -> l4 : a^0'=1, ret_returnone3^0'=1, tmp^0'=tmp^0, T, cost: 1
	New rule:
	l6 -> l4 : a^0'=1, ret_returnone3^0'=1, T, cost: 1
