Proof step 8 from proof ac-in-09 (previous step)

fs = mkfs(class, ty, fieldvar), ∀ r, class1, st. r = jvmref ∨ (r ∈ addclass(class1, fis0, st) ↔ r ∈ st) ⊦ r ∈ addclass(class, (fs ' × val) ' + fis0, st) ↔ r ∈ st, r = jvmref

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 4:
⊦ addclass(class1, (mkfs(class1, ty, fieldvar) ' × val) ' + fis, st) = (addclass(class1, fis, st)[jvmref -- mkfs(class1, ty, fieldvar) ', val])
Proof step 7:
∀ r, class1, st. r = jvmref ∨ (r ∈ addclass(class1, fis0, st) ↔ r ∈ st) ⊦ r = jvmref, r ∈ addclass(class, fis0, st) ↔ r ∈ st

Rule argument
