Proof step 1 from proof inv-flashsize-append (conclusion)

⊦ inv-flashsize(x + a ', lax + ladr ') ↔ inv-flashsize(x, lax) ∧ ladr.size = a.flashsize

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 2:
ladr = @(m, m0) ⊦ inv-flashsize(x + a ', lax + ladr ') ↔ inv-flashsize(x, lax) ∧ m0 = a.flashsize

Rule argument

spec: laddress name: elim seq: ⊦ m = ladr.off ∧ m0 = ladr.size ↔ ladr = @(m, m0) subst: [ladr, m, m0] → [ladr, m, m0]

Additional information

Used simplifier rules: ⊦ m = ladr.off ∧ m0 = ladr.size ↔ ladr = @(m, m0); (elim) Used terms: ladr, m, m0
