Proof step 4 from proof init-put-14 (conclusion)

⊦ initundone(class1, st[r -- mkfs(class0, boolean_type, fieldvar) ', val]) ↔ initundone(class1, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ rk ≠ _uninit ∧ rk ≠ jvmref -- mkfs(class, void_type, `initstate' .field) ' → (initundone(class, st[rk, val]) ↔ initundone(class, st))
Proof step 2:
⊦ 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 3:
⊦ initundone(class1, st) ↔ (jvmref -- mkfs(class1, void_type, `initstate' .field) ') × initval(undone) ∈ st ∨ ¬ jvmref -- mkfs(class1, void_type, `initstate' .field) ' ∈ st ∧ _uninit ∈ st
