Proof step 9 from proof addobj-initundone (previous step)

⊦ r = jvmref, jvmref -- mkfs(class0, void_type, `initstate' .field) ' ∈ st ∧ st[jvmref -- mkfs(class0, void_type, `initstate' .field) '] = initval(undone) ∨ ¬ jvmref -- mkfs(class0, void_type, `initstate' .field) ' ∈ st ∧ _uninit ∈ addobj(r, class, sks, st) ↔ initundone(class0, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 4:
⊦ initundone(class1, st) ↔ (jvmref -- mkfs(class1, void_type, `initstate' .field) ') × initval(undone) ∈ st ∨ ¬ jvmref -- mkfs(class1, void_type, `initstate' .field) ' ∈ st ∧ _uninit ∈ st
Proof step 8:
⊦ r = jvmref, jvmref -- mkfs(class0, void_type, `initstate' .field) ' ∈ st ∧ st[jvmref -- mkfs(class0, void_type, `initstate' .field) '] = initval(undone) ∨ ¬ jvmref -- mkfs(class0, void_type, `initstate' .field) ' ∈ st ∧ _uninit ∈ addobj(r, class, sks, st) ↔ (jvmref -- mkfs(class0, void_type, `initstate' .field) ') × initval(undone) ∈ st ∨ ¬ jvmref -- mkfs(class0, void_type, `initstate' .field) ' ∈ st ∧ _uninit ∈ st
