Chained Linear Paths

Start location: l2
Program variables: x_promoted_1^0
   2: l2 -> l1 : x_promoted_1^0'=x_promoted_1^post1, (-x_promoted_1^post2+x_promoted_1^0 == 0 /\ x_promoted_1^post1 == 0), cost: 1

	Eliminating location l0 by chaining:

	Applied chaining

	First rule:
	l2 -> l0 : x_promoted_1^0'=x_promoted_1^post2, -x_promoted_1^post2+x_promoted_1^0 == 0, cost: 1
	Second rule:
	l0 -> l1 : x_promoted_1^0'=x_promoted_1^post1, x_promoted_1^post1 == 0, cost: 1
	New rule:
	l2 -> l1 : x_promoted_1^0'=x_promoted_1^post1, (-x_promoted_1^post2+x_promoted_1^0 == 0 /\ x_promoted_1^post1 == 0), cost: 1
	
	Applied deletion

	Removed the following rules: 0 1

Simplified Transitions

   3: l2 -> l1 : x_promoted_1^0'=0, T, cost: 1

	Propagated Equalities

	Original rule:
	l2 -> l1 : x_promoted_1^0'=x_promoted_1^post1, (-x_promoted_1^post2+x_promoted_1^0 == 0 /\ x_promoted_1^post1 == 0), cost: 1
	New rule:
	l2 -> l1 : x_promoted_1^0'=0, (0 == 0 /\ -x_promoted_1^post2+x_promoted_1^0 == 0), cost: 1
	
		propagated equality x_promoted_1^post1 = 0
		
	Propagated Equalities

	Original rule:
	l2 -> l1 : x_promoted_1^0'=0, (0 == 0 /\ -x_promoted_1^post2+x_promoted_1^0 == 0), cost: 1
	New rule:
	l2 -> l1 : x_promoted_1^0'=0, 0 == 0, cost: 1
	
		propagated equality x_promoted_1^post2 = x_promoted_1^0
		
	Simplified Guard

	Original rule:
	l2 -> l1 : x_promoted_1^0'=0, 0 == 0, cost: 1
	New rule:
	l2 -> l1 : x_promoted_1^0'=0, T, cost: 1
