Proof step 13 from proof lebs-write (previous step)

n = m ∨ adr.lnum = n ∧ adr ∈ ri ⊦ key ∈ ri, ∃ adr. adr.lnum = n ∧ adr ∈ ri[key, @(m, m0, m1)]

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 14:
adr = @(m2, m3, m4), n = m ∨ m2 = n ∧ adr ∈ ri ⊦ key ∈ ri, ∃ adr. adr.lnum = n ∧ adr ∈ ri[key, @(m, m0, m1)]

Rule argument

spec: address-data name: elim seq: ⊦ (m = adr.lnum ∧ m0 = adr.pos) ∧ m1 = adr.size ↔ adr = @(m, m0, m1) subst: [adr, m, m0, m1] → [adr, m2, m3, m4]

Additional information

Used simplifier rules: ⊦ (m = adr.lnum ∧ m0 = adr.pos) ∧ m1 = adr.size ↔ adr = @(m, m0, m1); (elim) Used terms: adr, m2, m3, m4
