Proof step 8 from proof normal-lookup-01 (conclusion)

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

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ normalmode(st) → ¬ is_return_mode(st[_mode])
Proof step 2:
⊦ normalmode(st) → st[_mode] = noval
Proof step 7:
normalmode(st) ⊦ r = jvmref, normalmode(st[r -- sk, val])

Rule argument

[emptyarg]
