Proof step 6 from proof okbytearray-isarray (previous step)

okbytearray(r, st) ⊦ is_array(r, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ is_array(r, st) ↔ r ≠ jvmref ∧ r -- _type ∈ st ∧ is_typevalue(st[r -- _type]) ∧ is_arraytype(st[r -- _type] .type) ∧ okarray(r, st[r -- _type] .type .type, st)
Proof step 2:
⊦ okbytearray(r, st) → st[r -- _type] = typeval(mkarraytype(byte_type))
Proof step 3:
⊦ ¬ okbytearray(jvmref, st)
Proof step 4:
⊦ ¬ r -- _type ∈ st → ¬ okbytearray(r, st)
Proof step 5:
⊦ ¬ okarray(r, byte_type, st) → ¬ okbytearray(r, st)

Rule argument

[crewrite-arg: is-any-array, F, [st, r] → [st, r]]
