Proof step 10 from proof normal-lookup-02 (conclusion)

⊦ st0 = st[r -- sk, val] ∧ newref(r, st) ∧ normalmode(st) → normalmode(st0)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ newref(r, st) ↔ r ≠ jvmref ∧ (∀ rk. rk ∈ st → rk .ref ≠ r)
Proof step 2:
⊦ normalmode(st) → ¬ is_return_mode(st[_mode])
Proof step 3:
⊦ normalmode(st) → st[_mode] = noval
Proof step 9:
normalmode(st), ∀ rk. rk ∈ st → rk .ref ≠ r ⊦ r = jvmref, normalmode(st[r -- sk, val])

Rule argument
