Proof step 8 from proof addbar-refval-01 (previous step)

# ints = m + 1, ∀ st, r, i, ints0. # ints0 < m + 1 → (0 ≤ i ∧ i < n→i(# ints0) → ints0 = [] ∨ is_bytevalue(addarray(r, byte_type, mkjavavalues(is2bs(ints0)), st)[r -- i '])) ⊦ ints = [], is_bytevalue(mkjavavalues(is2bs(ints)) .last)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 7:
⊦ bytes ≠ [] → mkjavavalues(bytes) .last = byteval(bytes .last)

Rule argument

[speclemmaarg: ,bytes ≠ [] → mkjavavalues(bytes) .last = byteval(bytes .last) ,[bytes] → [is2bs(ints)] ,F ,valuesfuns , ,mkvalues-last ]
