Proof step 6 from proof is_array-okbytearray (conclusion)

⊦ okbytearray(r, st) → is_array(str, r, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ is_array(str, r, st) ↔ ¬ ¬ ( type∃(str, st[r -- _type] .type) ∧ st[r -- _type] .type .jtelemtype ≠ void_type ∧ st[r -- _type] .type .jtelemtype ≠ abstract_type ∧ is_array(r, st))
Proof step 2:
⊦ okbytearray(r, st) → st[r -- _type] = typeval(mkarraytype(byte_type))
Proof step 5:
okbytearray(r, st) ⊦ is_array(r, st)

Rule argument
