Proof step 22 from proof prepost-get-pebs-for-wl (previous step)

# apebs = # wlar, wlar[m].ec = free-ecs(wlar).min, wlar[m].status = free, m < # wlar, bflipset-cons(bflipset, wlar), unique-sqns(apebs), valid-ebatbl(apebs, wlar, vols, vtblpnum1), valid-eraseq(q), valid-eraseq(wlar, q), valid-eraseq(apebs, q), valid-global-sqn(apebs, sqnum), valid-vtbl(apebs, vols, wlar, vtblpnum1), valid-wl(apebs, wlar) ⊦ # free-ecs(wlar) = 0, free-ecs(wlar) = ∅, VTBL_VOLID ∈ vols, vtblpnum1 ∈ q, ∃ m. m < # wlar ∧ wlar[m].ec < free-ecs(wlar).min + 2 * WL_THRESHOLD ∧ wlar[m].status = free

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 23:
# apebs = # wlar, wlar[m] = wl-entry(m0, stat), m0 = free-ecs(wlar).min, stat = free, m < # wlar, bflipset-cons(bflipset, wlar), unique-sqns(apebs), valid-ebatbl(apebs, wlar, vols, vtblpnum1), valid-eraseq(apebs, q), valid-eraseq(wlar, q), valid-eraseq(q), valid-global-sqn(apebs, sqnum), valid-vtbl(apebs, vols, wlar, vtblpnum1), valid-wl(apebs, wlar) ⊦ # free-ecs(wlar) = 0, free-ecs(wlar) = ∅, vtblpnum1 ∈ q, VTBL_VOLID ∈ vols, ∃ m. m < # wlar ∧ wlar[m].ec < free-ecs(wlar).min + 2 * WL_THRESHOLD ∧ wlar[m].status = free

Rule argument

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

Additional information

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