Proof step 34 from proof unchNorec-isobj (previous step)

unchangedNorec(r, st, st0), is_obj(r, st) ⊦ is_obj(r, st0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ is_obj(r, st) ↔ r ≠ jvmref ∧ r -- _type ∈ st ∧ is_typevalue(st[r -- _type]) ∧ is_classtype(st[r -- _type] .type) ∧ is_obj(r, st[r -- _type] .type .class, st)
Proof step 33:
unchangedNorec(r, st, st0), is_obj(r, st) ⊦ r ≠ jvmref ∧ r -- _type ∈ st0 ∧ is_typevalue(st0[r -- _type]) ∧ is_classtype(st0[r -- _type] .type) ∧ is_obj(r, st0[r -- _type] .type .class, st0)
