Proof step 5 from proof junkrefs-bytearray (conclusion)

⊦ junkrefs(str, r ' + refs, mkarraytype(byte_type), st) ↔ r ≠ jvmref ∧ ¬ okbytearray(r, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ is_primtype(ty) → (junkrefs(str, r ' + refs, mkarraytype(ty), st) ↔ r ≠ jvmref ∧ ¬ okarray(r, ty, st))
Proof step 4:
is_primtype(byte_type) ⊦ r ≠ jvmref ∧ ¬ okarray(r, byte_type, st) ↔ r ≠ jvmref ∧ ¬ okbytearray(r, st)

Rule argument

[crewrite-arg: junkrefs-primarray , F , [st, ty, refs, r, str] → [st, byte_type, refs, r, str] ]
