Proof step 2 from proof nodes-write-refsize (previous step)

st[n] = mkblock(x, lax, m0), n ∈ st ⊦ nodes(st[n, mkblock(x, lax, m1)]) = nodes(st)

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: store, inst: address-store name: k-Extension seq: ⊦ ast = ast0 ↔ (∀ adr. (adr ∈ ast ↔ adr ∈ ast0) ∧ (adr ∈ ast → ast[adr] = ast0[adr])) subst: [ast0, ast] → [nodes(st), nodes(st[n, mkblock(x, lax, m1)])] flags: <all paths>

Additional information

Used terms: nodes(st), nodes(st[n, mkblock(x, lax, m1)])
