Proof step 2 from proof okarray-put-03 (previous step)

⊦ r = r0, okarray(refval(r), byte_type, i, st[r0 -- sk, val0]) ↔ okarray(refval(r), byte_type, i, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ ¬ is_classtype(ty) ∧ ¬ is_arraytype(ty) ∧ r ≠ r0 → (okarray(refval(r), ty, i, st[r0 -- sk, val0]) ↔ okarray(refval(r), ty, i, st))

Rule argument

[crewrite-arg: okarray-02 , F , [val0, sk, r0, st, i, ty, r] → [val0, sk, r0, st, i, byte_type, r] ]
