Proof step 5 from proof classof-03 (conclusion)

⊦ classof(r, class1, st) → (st[r -- _type] .type ≠ mkclasstype(class1) ↔ false)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ classof(r, class1, st) → r ∈ st
Proof step 2:
⊦ classof(r, class1, st) → r ≠ jvmref
Proof step 4:
classof(r, class1, st), r ∈ st ⊦ st[r -- _type] .type = mkclasstype(class1), r = jvmref

Rule argument

[emptyarg]
