Proof step 14 from proof ac-init-01 (previous step)

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

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 5:
⊦ initundone(class1, st) ↔ (jvmref -- mkfs(class1, void_type, `initstate' .field) ') × initval(undone) ∈ st ∨ ¬ jvmref -- mkfs(class1, void_type, `initstate' .field) ' ∈ st ∧ _uninit ∈ st
Proof step 13:
initundone(class, addclass(class, fis0, st)[jvmref -- mkfs(class, ty, fieldvar) ', val]), void_type ≠ ty ∨ `initstate' .field ≠ fieldvar ⊦ mkfs(class, void_type, `initstate' .field) ' ∈ fis0, (jvmref -- mkfs(class, void_type, `initstate' .field) ') × initval(undone) ∈ addclass(class, fis0, st) ∨ ¬ jvmref -- mkfs(class, void_type, `initstate' .field) ' ∈ addclass(class, fis0, st) ∧ _uninit ∈ addclass(class, fis0, st)
