Proof step 7 from proof junkref-ac (previous step)

⊦ r = jvmref, junkref(str, r, addclass(class, [], st)) ↔ junkref(str, r, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ addclass(class1, [], st) = st[jvmref -- mkfs(class1, void_type, `initstate' .field) ', initval(done)]
Proof step 6:
⊦ r = jvmref, junkref(str, r, st[jvmref -- mkfs(class, void_type, `initstate' .field) ', initval(done)]) ↔ junkref(str, r, st)

Rule argument

[speclemmaarg: , addclass(class1, [], st) = st[jvmref -- mkfs(class1, void_type, `initstate' .field) ', initval(done)] ,[st, class1] → [st, class] ,F ,addfuns , ,addclass-base ]
