Proof step 6 from proof add-class (previous step)

⊦ r = r0, r0 ≠ jvmref ∧ r0 -- _type ∈ addobj(r, class1, fis, st) ∧ (addobj(r, class1, fis, st)[r0 -- _type]) = typeval(mkclasstype(class0)) ↔ classof(r0, class0, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ r ≠ r0 → (r -- sk ∈ addobj(r0, class1, fis, st) ↔ r -- sk ∈ st)
Proof step 3:
⊦ r ≠ r0 → (addobj(r, class1, fis, st)[r0 -- sk]) = st[r0 -- sk]
Proof step 5:
⊦ r = r0, r0 ≠ jvmref ∧ r0 -- _type ∈ st ∧ st[r0 -- _type] = typeval(mkclasstype(class0)) ↔ classof(r0, class0, st)
