Proof step 3 from proof init-uninit-01 (previous step)

init(st), _uninit ∈ st, ∀ rk. rk ∈ st ∧ rk .ref = jvmref ∧ is_fskey(rk .key) ∧ rk .key .fs .type = void_type ∧ rk .key .fs .field = `initstate' .field → st[rk] = initval(undone) ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ init(st) ↔ ¬ _uninit ∈ st ∧ (∀ rk. rk ∈ st ∧ rk .ref = jvmref ∧ is_fskey(rk .key) ∧ rk .key .fs .type = void_type ∧ rk .key .fs .field = `initstate' .field → st[rk] ≠ initval(undone) ∧ st[rk] ≠ initval(error))

Rule argument

[crewrite-arg: init-def, F, [st] → [st]]
