Proof step 5 from proof inv-io-read (previous step)

# buf = n1 + n0 + n, buf0 = buf, m < # pebs, mtd-cons(pebs), n0 + n ≤ # buf, m0 + n ≤ PEB_SIZE, ¬ pebs[m].bad ⊦ ⟪ubi_io_read#(m, m0, n0, n, pebs; buf; bitflips, err)⟫ ( # buf = # buf0 ∧ range=(buf, 0, buf0, 0, n0) ∧ range=(buf, n0 + n, buf0, n0 + n, n1) ∧ (err = ESUCCESS ∨ ⌊err⌋ ) ∧ (err = ESUCCESS → subarray(buf, n0, n) = subarray(pebs[m].data, m0, n)))

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 6:
# buf = n1 + n0 + n, pebs[m] = mkpeb(buf1, m1, boolvar), ¬ boolvar, buf0 = buf, m < # pebs, mtd-cons(pebs), m0 + n ≤ PEB_SIZE, n0 + n ≤ # buf ⊦ ⟪ubi_io_read#(m, m0, n0, n, pebs; buf; bitflips, err)⟫ ( # buf = # buf0 ∧ range=(buf, 0, buf0, 0, n0) ∧ range=(buf, n0 + n, buf0, n0 + n, n1) ∧ (err = ESUCCESS ∨ ⌊err⌋ ) ∧ (err = ESUCCESS → subarray(buf, n0, n) = subarray(buf1, m0, n)))

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[m], buf1, m1, boolvar]

Additional information

Used simplifier rules: ⊦ (buf = peb.data ∧ m = peb.fill) ∧ (boolvar ↔ peb.bad) ↔ peb = mkpeb(buf, m, boolvar); (elim) Used terms: pebs[m], buf1, m1, boolvar
