Proof step 23 from proof ac-init (previous step)

initdone(class, addclass(class, fis0, st)), void_type ≠ ty ∨ `initstate' .field ≠ fieldvar ⊦ mkfs(class, void_type, `initstate' .field) ' ∈ fis0, ¬ initerror(class, addclass(class, fis0, st)[jvmref -- mkfs(class, ty, fieldvar) ', val]) ∧ ¬ initundone(class, addclass(class, fis0, st)[jvmref -- mkfs(class, ty, fieldvar) ', val])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 9:
⊦ initdone(class1, st) ↔ ¬ initerror(class1, st) ∧ ¬ initundone(class1, st)
Proof step 22:
¬ initerror(class, addclass(class, fis0, st)) ∧ ¬ initundone(class, addclass(class, fis0, st)), void_type ≠ ty ∨ `initstate' .field ≠ fieldvar ⊦ mkfs(class, void_type, `initstate' .field) ' ∈ fis0, ¬ initerror(class, addclass(class, fis0, st)[jvmref -- mkfs(class, ty, fieldvar) ', val]) ∧ ¬ initundone(class, addclass(class, fis0, st)[jvmref -- mkfs(class, ty, fieldvar) ', val])
