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

apebs[m] = mkpeb(aehdr, avhdr, buf0, m1, false), avhdr.valid?, aehdr.valid?, m < # apebs, abs(pebs, apebs), is-aligned(n0, EB_PAGE_SIZE), is-aligned(m0, EB_PAGE_SIZE), mtd-cons(pebs), ubi-io-inv(apebs), n + n0 ≤ # buf, m0 + n0 ≤ LEB_SIZE, m1 ≤ m0 ⊦ ⟪ubi_io_write_data#(m, m0, n, n0, buf, EB_PAGE_SIZE; pebs; err)⟫ ⟨aubi_io_write_data#(m, m0, n, n0, buf; apebs; err0)⟩ (abs(pebs, apebs) ∧ err = err0)

Heuristic nonrecursive calls applied rule call right

And obtained the following new goals

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

Additional information

Used simplifier rules: ubi_io_write_data#(PNUM, OFFSET, N0, N, BUF, PAGESIZE; PEBS; ERR) {if PNUM < # PEBS ∧ ¬ PEBS[PNUM].bad ∧ PEBS[PNUM].fill ≤ OFFSET + 2 * EB_PAGE_SIZE ∧ OFFSET + N ≤ LEB_SIZE ∧ N0 + N ≤ # BUF ∧ is-aligned(OFFSET, EB_PAGE_SIZE) ∧ is-aligned(N, EB_PAGE_SIZE) then mtd_asm_write# (PNUM, OFFSET + 2 * PAGESIZE, N0, N, BUF; PEBS; ERR) else abort };
