Proof step 7 from proof instore-addobj-rec (previous step)

instore(r, class, [], addobj(r1, class1, fis1, st)) ⊦ instore(r, class, [], st), r = r1

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ instore(r, class, [], st) ↔ r ≠ jvmref ∧ r -- _type ∈ st ∧ st[r -- _type] = typeval(mkclasstype(class))
Proof step 6:
r ≠ jvmref ∧ r -- _type ∈ addobj(r1, class1, fis1, st) ∧ (addobj(r1, class1, fis1, st)[r -- _type]) = typeval(mkclasstype(class)) ⊦ instore(r, class, [], st), r = r1

Rule argument

[speclemmaarg: , instore(r, class, [], st) ↔ r ≠ jvmref ∧ r -- _type ∈ st ∧ st[r -- _type] = typeval(mkclasstype(class)) ,[st, class, r] → [addobj(r1, class1, fis1, st), class, r] ,F ,okfuns , ,instore-empty ]
