Proof step 11 from proof is_valid_ref-addobj-01 (previous step)

is_obj(r, addobj(r, class, fis, st)), class+∃(str, class) ∧ ¬ is_abstract(class) ∨ type∃(str, (addobj(r, class, fis, st)[r -- _type]) .type) ∧ (addobj(r, class, fis, st)[r -- _type]) .type .jtelemtype ≠ void_type ∧ (addobj(r, class, fis, st)[r -- _type]) .type .jtelemtype ≠ abstract_type ∧ is_array(r, addobj(r, class, fis, st)) ⊦ _type ∈ fis, is_obj(str, r, addobj(r, class, fis, st))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 6:
¬ _type ∈ fis ⊦ (addobj(r, class1, fis, st)[r -- _type]) = typeval(mkclasstype(class1))
Proof step 7:
⊦ is_obj(r, st) → ¬ is_array(r, st)
Proof step 10:
is_obj(r, addobj(r, class, fis, st)), class+∃(str, class) ⊦ _type ∈ fis, is_obj(str, r, addobj(r, class, fis, st)), is_abstract(class)
