Proof step 2 from proof junkref-addarray-02 (previous step)

junkref(str, r, addarray(r0, ty, i, st)), newref(r0, st) ⊦ r0 = jvmref, junkref(str, r, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ ¬ junkref(str, r, st) ∧ st ⊆ st1 → ¬ junkref(str, r, st1)

Rule argument

[crewrite-arg: junkref-subset , F , [str, r, st, st1] → [str, r, st, addarray(r0, ty, i, st)] ]
