Proof step 7 from proof exactarray-put-07 (previous step)

⊦ r = val .refval, exactarray(val, ty, i, st[r -- sk, val0]) ↔ exactarray(val, ty, i, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ exactarray(val, ty, i, st) ↔ exactreftype(val, mkarraytype(ty), st) ∧ val .refval ≠ jvmref ∧ (val .refval -- _length) × intval(i) ∈ st ∧ is_arrayref(val .refval, i, st)
Proof step 6:
⊦ r = val .refval, exactreftype(val, mkarraytype(ty), st[r -- sk, val0]) ∧ val .refval ≠ jvmref ∧ (val .refval -- _length) × intval(i) ∈ st[r -- sk, val0] ∧ is_arrayref(val .refval, i, st[r -- sk, val0]) ↔ exactarray(val, ty, i, st)

Rule argument

[crewrite-arg: exactarray-01 , F , [st, i, ty, val] → [st[r -- sk, val0], i, ty, val] ]
