Proof step 20 from proof prepost-wl-get-free-min (previous step)

¬ boolvar ↔ free-ecs(wlar, m0) = ∅, m0 < # wlar, boolvar → n = free-ecs(wlar, m0).min ⊦ (boolvar → n = free-ecs(wlar, m0 + 1).min) ∧ (¬ boolvar ↔ free-ecs(wlar, m0 + 1) = ∅), wlar[m0].status = free ∧ (¬ boolvar ∨ wlar[m0].ec < n)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Rule argument

spec: wlentry name: elim-02 seq: ⊦ m = wle.ec ∧ stat = wle.status ↔ wle = wl-entry(m, stat) subst: [wle, m, stat] → [wlar[m0], m, stat]

Additional information

Used simplifier rules: ⊦ m = wle.ec ∧ stat = wle.status ↔ wle = wl-entry(m, stat); (elim) Used terms: wlar[m0], m, stat
