Proof step 3 from proof in-write-refsize (previous step)

n ∈ st ⊦ adr ∈ st[n, st[n].ref-size:= m] ↔ adr ∈ st

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 4:
⊦ adr ∈ st ↔ adr.lnum ∈ st ∧ @(adr.pos, adr.size) ∈ st[adr.lnum].ladrlist
Proof step 5:
n ∈ st ⊦ adr.lnum ∈ st[n, st[n].ref-size:= m] ∧ @(adr.pos, adr.size) ∈ st[n, st[n].ref-size:= m][adr.lnum].ladrlist ↔ adr ∈ st

Rule argument

spec: <toplevel> name: in seq: ⊦ adr ∈ st ↔ adr.lnum ∈ st ∧ @(adr.pos, adr.size) ∈ st[adr.lnum].ladrlist subst: [st, adr] → [st[n, st[n].ref-size:= m], adr] flags: <all paths>

Additional information

Used terms: st[n, st[n].ref-size:= m], adr
