Proof step 2 from proof okarray-init (previous step)

⊦ r = r0, okarray(refval(r), byte_type, i, addarray(r0, ty0, vals, st)) ↔ okarray(refval(r), byte_type, i, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ r ≠ val .refval → (okarray(val, ty0, i, addarray(r, ty, vals, st)) ↔ okarray(val, ty0, i, st))

Rule argument

[crewrite-arg: add-okarray , F , [st, vals, ty, r, i, ty0, val] → [st, vals, ty0, r0, i, byte_type, refval(r)] ]
