Proof step 9 from proof validrefkeynotnull-notnewref (previous step)

st[rk] = refval(r), newref(r, st), rk ∈ st, validrefvalnotnull(str, refval(r), ty, st) ⊦ r = jvmref

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ validrefvalnotnull(str, val, ty, st) ↔ is_referencevalue(val) ∧ validrefnotnull(str, val .refval, ty, st)
Proof step 8:
st[rk] = refval(r), newref(r, st), rk ∈ st, is_referencevalue(refval(r)) ∧ validrefnotnull(str, refval(r) .refval, ty, st) ⊦ r = jvmref

Rule argument

[crewrite-arg: validrefvalnotnull-def , F , [st, ty, val, str] → [st, ty, refval(r), str] ]
