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

∀ class1, st, val. class1 = `java.lang.Object' .class ∨ addclass(class1, fis0, st[_out, val]) = (addclass(class1, fis0, st)[_out, val]) ⊦ fs .class = class1, class1 = `java.lang.Object' .class, addclass(class1, fis0, st[_out, val]) = (addclass(class1, fis0, st)[_out, val])

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 22:
fs = mkfs(class, ty, fieldvar), ∀ class1, st, val. class1 = `java.lang.Object' .class ∨ addclass(class1, fis0, st[_out, val]) = (addclass(class1, fis0, st)[_out, val]) ⊦ class = class1, class1 = `java.lang.Object' .class, addclass(class1, fis0, st[_out, val]) = (addclass(class1, fis0, st)[_out, val])

Rule argument
