Proof step 6 from proof ao-init-01 (previous step)

⊦ r = jvmref, jvmref -- mkfs(class1, void_type, `initstate' .field) ' ∈ st ∧ st[jvmref -- mkfs(class1, void_type, `initstate' .field) '] = initval(undone) ∨ _uninit ∈ addobj(r, class2, fis, st) ∧ ¬ jvmref -- mkfs(class1, void_type, `initstate' .field) ' ∈ st ↔ (jvmref -- mkfs(class1, void_type, `initstate' .field) ') × initval(undone) ∈ st ∨ ¬ jvmref -- mkfs(class1, void_type, `initstate' .field) ' ∈ st ∧ _uninit ∈ st

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 5:
⊦ r ≠ jvmref → (_uninit ∈ addobj(r, class, fis, st) ↔ _uninit ∈ st)
