Proof step 5 from proof hasSharing-addarray (previous step)

hasSharing(r, addarray(newref(st), ty, vals, st)) ⊦ junkref(str, r, st), hasSharing(r, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ ¬ junkref(str, r, st) ∧ st ⊆ st1 ∧ ¬ hasSharing(r, st) → ¬ hasSharing(r, st1)
Proof step 4:
¬ (¬ junkref(str, r, st) ∧ st ⊆ addarray(newref(st), ty, vals, st) ∧ ¬ hasSharing(r, st)), hasSharing(r, addarray(newref(st), ty, vals, st)) ⊦ junkref(str, r, st), hasSharing(r, st)

Rule argument

[crewrite-arg: hasSharing-subset , F , [str, r, st, st1] → [str, r, st, addarray(newref(st), ty, vals, st)] ]
