Proof step 136 from proof compat-addobj (previous step)

st[r0 -- _type] = typeval(ty), is_classtype(ty), class+∃(str, ty .class), r0 ∈ st, r0 -- _type ∈ st, compatstatic(str, st), compatmode(str, st), newref(r, st), is_predefined_class(class), compatobj(str, r0, st) ⊦ r0 = jvmref, r = jvmref, compatobj(str, r0, addobj(r, class, [], st))

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 135:
ty = mkclasstype(class0), st[r0 -- _type] = typeval(ty), is_classtype(ty), class+∃(str, class0), r0 ∈ st, r0 -- _type ∈ st, compatstatic(str, st), compatmode(str, st), newref(r, st), is_predefined_class(class), compatobj(str, r0, st) ⊦ r0 = jvmref, r = jvmref, compatobj(str, r0, addobj(r, class, [], st))
