Proof step 28 from proof addarrays-initdone (conclusion)

⊦ initdone(class, addarrays(refs, ty, ints, i, st)) ↔ initdone(class, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ initdone(class1, st) ↔ ¬ initerror(class1, st) ∧ ¬ initundone(class1, st)
Proof step 27:
⊦ ¬ initerror(class, addarrays(refs, ty, ints, i, st)) ∧ ¬ initundone(class, addarrays(refs, ty, ints, i, st)) ↔ initdone(class, st)

Rule argument

[speclemmaarg: , initdone(class1, st) ↔ ¬ initerror(class1, st) ∧ ¬ initundone(class1, st) ,[st, class1] → [addarrays(refs, ty, ints, i, st), class] ,F ,storefuns , ,initdone ]
