Proof step 3 from proof refine-read-data (previous step)

buf = buf0, m < # apebs, abs(pebs, apebs), mtd-cons(pebs), ubi-io-inv(apebs), n + n0 ≤ # buf0, m0 + n0 ≤ LEB_SIZE, ¬ apebs[m].bad ⊦ ⟪ubi_io_read_data#(m, m0, n, n0, EB_PAGE_SIZE, pebs; buf; bitflips, err)⟫ ⟨aubi_io_read_data#(m, m0, n, n0, apebs; buf0; isbad, err0)⟩ (buf = buf0 ∧ (bitflips ↔ isbad) ∧ err = err0)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 4:
apebs[m] = mkpeb(aehdr, avhdr, buf1, m1, boolvar), ¬ boolvar, buf = buf0, m < # apebs, abs(pebs, apebs), mtd-cons(pebs), ubi-io-inv(apebs), m0 + n0 ≤ LEB_SIZE, n + n0 ≤ # buf0 ⊦ ⟪ubi_io_read_data#(m, m0, n, n0, EB_PAGE_SIZE, pebs; buf; bitflips, err)⟫ ⟨aubi_io_read_data#(m, m0, n, n0, apebs; buf0; isbad, err0)⟩ (buf = buf0 ∧ (bitflips ↔ isbad) ∧ err = err0)

Rule argument

spec: apeb name: elim seq: ⊦ ( ( (aehdr = apeb.echdr ∧ avhdr = apeb.vidhdr) ∧ buf = apeb.data) ∧ m = apeb.fill) ∧ (boolvar ↔ apeb.bad) ↔ apeb = mkpeb(aehdr, avhdr, buf, m, boolvar) subst: [apeb, aehdr, avhdr, buf, m, boolvar] → [apebs[m], aehdr, avhdr, buf1, m1, boolvar]

Additional information

Used simplifier rules: ⊦ ( ((aehdr = apeb.echdr ∧ avhdr = apeb.vidhdr) ∧ buf = apeb.data) ∧ m = apeb.fill) ∧ (boolvar ↔ apeb.bad) ↔ apeb = mkpeb(aehdr, avhdr, buf, m, boolvar); (elim) Used terms: apebs[m], aehdr, avhdr, buf1, m1, boolvar
