Proof step 8 from proof isobj-addobj-03 (previous step)

∀ sk. sk ∈ instfields(class0) → goodfieldandtype(r, sk, addobj(r0, class, fis, st)), st[r -- _type] = typeval(mkclasstype(class0)), r -- _type ∈ st, r ∈ st ⊦ ∀ sk. sk ∈ instfields(class0) → goodfieldandtype(r, sk, st), r = jvmref, r = r0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 6:
⊦ r ≠ r0 → (goodfieldandtype(r, sk, addobj(r0, class, fis, st)) ↔ goodfieldandtype(r, sk, st))
Proof step 7:
st[r -- _type] = typeval(mkclasstype(class0)), sk ∈ instfields(class0), r -- _type ∈ st, r ∈ st, ∀ sk0. sk0 ∈ instfields(class0) → goodfieldandtype(r, sk0, st) ⊦ r = jvmref, r = r0, goodfieldandtype(r, sk, st)
