Proof step 8 from proof refine-write-data (previous step)

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

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 9:
apebs[m3] = mkpeb(aehdr, avhdr, buf0, m2, false), pebs[m3] = mkpeb(buf1, m, boolvar), ¬ boolvar, aehdr.valid?, avhdr.valid?, m3 < # apebs, m3 < # pebs, 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, m ≤ m0 + 2 * EB_PAGE_SIZE ⊦ ⟪mtd_asm_write#(m3, m0 + 2 * EB_PAGE_SIZE, n2, n1, buf; pebs; err)⟫ ⟨aubi_io_write_data#(m3, m0, n2, n1, buf; apebs; err0)⟩ (abs(pebs, apebs) ∧ err = err0)

Rule argument

spec: peb name: elim seq: ⊦ (buf = peb.data ∧ m = peb.fill) ∧ (boolvar ↔ peb.bad) ↔ peb = mkpeb(buf, m, boolvar) subst: [peb, buf, m, boolvar] → [pebs[m3], buf1, m, boolvar]

Additional information

Used simplifier rules: ⊦ (buf = peb.data ∧ m = peb.fill) ∧ (boolvar ↔ peb.bad) ↔ peb = mkpeb(buf, m, boolvar); (elim) Used terms: pebs[m3], buf1, m, boolvar
