Proof step 4 from proof instore-afterputs (previous step)

st[r -- _type] = typeval(mkclasstype(class)), r -- _type ∈ st, r -- sk ∈ st, r ∈ st ⊦ r = jvmref, _type = sk, instore(r, class, [], st[r -- sk, refval(r1)])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ instore(r, class, [], st) ↔ r ≠ jvmref ∧ r -- _type ∈ st ∧ st[r -- _type] = typeval(mkclasstype(class))

Rule argument

[crewrite-arg: instore-empty , F , [st, class, r] → [st[r -- sk, refval(r1)], class, r] ]
