Proof step 5 from proof refine-read-data (previous step)

apebs[m] = mkpeb(aehdr, avhdr, buf1, m1, false), buf = buf0, m < # apebs, abs(pebs, apebs), mtd-cons(pebs), ubi-io-inv(apebs), n + n0 ≤ # buf0, m0 + n0 ≤ LEB_SIZE ⊦ ⟪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 nonrecursive calls applied rule call right

And obtained the following new goals

Proof step 6:
apebs[m3] = mkpeb(aehdr, avhdr, buf1, m2, false), buf = buf0, m = EB_PAGE_SIZE, m1 = m3, n = n1, n0 = n2, m3 < # apebs, abs(pebs, apebs), mtd-cons(pebs), ubi-io-inv(apebs), m0 + n1 ≤ LEB_SIZE, n2 + n1 ≤ # buf0 ⊦ ⟪if m1 < # pebs ∧ ¬ pebs[m1].bad ∧ m0 + n ≤ LEB_SIZE ∧ n0 + n ≤ # buf then ubi_io_read#(m1, m0 + 2 * m, n0, n, pebs; buf; bitflips, err) else abort⟫ ⟨aubi_io_read_data#(m3, m0, n2, n1, apebs; buf0; isbad, err0)⟩ (buf = buf0 ∧ (bitflips ↔ isbad) ∧ err = err0)
