Proof step 9 from proof okclass-init (previous step)

⊦ r = r0, reftypep(refval(r0), addarray(r, ty, vals, st)) ∧ (r0 ≠ jvmref → r0 -- _type ∈ st ∧ st[r0 -- _type] = typeval(mkclasstype(class1))) ↔ okclass(refval(r0), class1, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 4:
⊦ okclass(val, class1, st) ↔ reftypep(val, st) ∧ (val .refval ≠ jvmref → val .refval -- _type ∈ st ∧ st[val .refval -- _type] = typeval(mkclasstype(class1)))
Proof step 8:
⊦ r = r0, reftypep(refval(r0), addarray(r, ty, vals, st)) ∧ (r0 ≠ jvmref → r0 -- _type ∈ st ∧ st[r0 -- _type] = typeval(mkclasstype(class1))) ↔ reftypep(refval(r0), st) ∧ (refval(r0) .refval ≠ jvmref → refval(r0) .refval -- _type ∈ st ∧ st[refval(r0) .refval -- _type] = typeval(mkclasstype(class1)))
