Proof step 8 from proof lf-vtbl-info (previous step)

avhdr.leb = VTBL_LNUM, wlar[n].status = used, avhdr.vol = VTBL_VOLID, apebs[n] = mkpeb(aehdr, avhdr, buf, m, boolvar), n < # apebs, n < # wlar, is-encoded(to-vtbl(vols), buf), valid-eraseq(wlar, q), n ∈ q ⊦

Heuristic elimination applied rule insert elim lemma

And closed the goal!

Rule argument

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

Additional information

Used simplifier rules: lf-used-info: ⊦ n < # wlar ∧ wlar[n] = wl-entry(m, used) ∧ valid-eraseq(wlar, q) → ¬ n ∈ q;% ⊦ m = wle.ec ∧ stat = wle.status ↔ wle = wl-entry(m, stat); (elim) Used terms: wlar[n], m0, stat
