Proof step 10 from proof exactarray-02-01 (previous step)

⊦ r = r0, r ∈ st ∧ r -- _type ∈ st ∧ is_typevalue(st[r -- _type]) ∧ st[r -- _type] .type = mkarraytype(ty) ∧ r ≠ jvmref ∧ r -- _length ∈ st ∧ st[r -- _length] = intval(i) ∧ is_arrayref(r, i, st) ↔ exactarray(refval(r), ty, i, st), is_classtype(ty), is_arraytype(ty)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ 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 9:
⊦ r = r0, r ∈ st ∧ r -- _type ∈ st ∧ is_typevalue(st[r -- _type]) ∧ st[r -- _type] .type = mkarraytype(ty) ∧ r ≠ jvmref ∧ r -- _length ∈ 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), is_classtype(ty), is_arraytype(ty)

Rule argument
