Proof step 33 from proof ac-in (previous step)

⊦ jvmref -- mkfs(class1, ty, fieldvar) ' ∈ addclass(class1, fis, st) ↔ ty = void_type ∧ fieldvar = `initstate' .field ∨ mkfs(class1, ty, fieldvar) ' ∈ fis ∨ jvmref -- mkfs(class1, ty, fieldvar) ' ∈ st

User applied rule structural induction

And obtained the following new goals

Proof step 1:
⊦ addclass(class1, [], st) = st[jvmref -- mkfs(class1, void_type, `initstate' .field) ', initval(done)]
Proof step 32:
∀ class1, ty, fieldvar, st. jvmref -- mkfs(class1, ty, fieldvar) ' ∈ addclass(class1, fis0, st) ↔ ty = void_type ∧ fieldvar = `initstate' .field ∨ mkfs(class1, ty, fieldvar) ' ∈ fis0 ∨ jvmref -- mkfs(class1, ty, fieldvar) ' ∈ st ⊦ jvmref -- mkfs(class1, ty, fieldvar) ' ∈ addclass(class1, fv + fis0, st) ↔ ty = void_type ∧ fieldvar = `initstate' .field ∨ mkfs(class1, ty, fieldvar) ' ∈ fv + fis0 ∨ jvmref -- mkfs(class1, ty, fieldvar) ' ∈ st
