Proof step 10 from proof isobj-put-02 (previous step)

r -- _type ∈ st, is_typevalue(st[r -- _type]), is_classtype(st[r -- _type] .type), is_obj(r, st[r -- _type] .type .class, st), okval(val, ty), r ∈ st ⊦ ty = void_type, r = jvmref, is_obj(r, st[r1 -- mkfs(class, ty, fieldvar) ', val])

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 9:
st[r -- _type] .type = mkclasstype(class0), r -- _type ∈ st, is_typevalue(st[r -- _type]), is_classtype(st[r -- _type] .type), is_obj(r, class0, st), okval(val, ty), r ∈ st ⊦ ty = void_type, r = jvmref, is_obj(r, st[r1 -- mkfs(class, ty, fieldvar) ', val])

Rule argument

[speclemmaarg: ,is_classtype(ty) → (class = ty .class ↔ ty = mkclasstype(class)) ,[ty, class] → [st[r -- _type] .type, class0] ,T ,javatype , ,elim-02 ]
