Proof step 14 from proof addclass-exactarray (previous step)

⊦ r = jvmref, exactreftype(refval(r), mkarraytype(ty), addclass(class0, fis, st)) ∧ r -- _length ∈ addclass(class0, fis, st) ∧ st[r -- _length] = intval(i) ∧ is_arrayref(r, i, st) ↔ exactarray(refval(r), ty, i, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 4:
⊦ 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 13:
⊦ r = jvmref, exactreftype(refval(r), mkarraytype(ty), addclass(class0, fis, st)) ∧ r -- _length ∈ addclass(class0, fis, st) ∧ st[r -- _length] = intval(i) ∧ is_arrayref(r, i, st) ↔ exactreftype(refval(r), mkarraytype(ty), st) ∧ refval(r) .refval ≠ jvmref ∧ (refval(r) .refval -- _length) × intval(i) ∈ st ∧ is_arrayref(refval(r) .refval, i, st)
