Proof step 26 from proof isobj-addarray (previous step)

r1 -- _type ∈ st, is_typevalue(st[r1 -- _type]), is_classtype(st[r1 -- _type] .type), is_obj(r1, st[r1 -- _type] .type .class, addarray(r0, ty, vals, st)), r1 ∈ st ⊦ r1 = r0, r1 = jvmref, is_obj(r1, st)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 25:
st[r1 -- _type] .type = mkclasstype(class), r1 -- _type ∈ st, is_typevalue(st[r1 -- _type]), is_classtype(st[r1 -- _type] .type), is_obj(r1, class, addarray(r0, ty, vals, st)), r1 ∈ st ⊦ r1 = r0, r1 = jvmref, is_obj(r1, st)

Rule argument

[speclemmaarg: ,is_classtype(ty) → (class = ty .class ↔ ty = mkclasstype(class)) ,[ty, class] → [st[r1 -- _type] .type, class] ,T ,javatype , ,elim-02 ]
