Proof step 20 from proof wand-shift (previous step)

P0(H1), P1(H), P2(H ∪ H0), H1 ⊥ H0, H ⊥ H1, H ⊥ H0 ⊦ (H ∪ H1) ∪ H0 = H1 ∪ H ∪ H0

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 21:
⊦ H0 ⊥ H1 → H1 ∪ H0 = H0 ∪ H1
Proof step 22:
P0(H1), P1(H), P2(H ∪ H0), H ⊥ H0, H ⊥ H1, H1 ⊥ H0, H1 ⊥ H ⊦ (H1 ∪ H) ∪ H0 = H1 ∪ H ∪ H0

Rule argument

spec: heap name: uni-com seq: ⊦ H0 ⊥ H1 → H1 ∪ H0 = H0 ∪ H1 subst: [H0, H1] → [H1, H] flags: <all paths>

Additional information

Used simplifier rules: ⊦ H0 ⊥ H1 → H1 ⊥ H0; (s) Used terms: H1, H
