Proof step 36 from proof okbytearray-validref (conclusion)

⊦ validref(str, r, mkarraytype(byte_type), st) ↔ okbytearray(r, st) ∨ r = jvmref

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ ¬ okbytearray(r, st) ∧ r ≠ jvmref → ¬ validref(str, r, mkarraytype(byte_type), st)
Proof step 35:
¬ (¬ okbytearray(r, st) ∧ r ≠ jvmref) ⊦ validref(str, r, mkarraytype(byte_type), st) ↔ okbytearray(r, st) ∨ r = jvmref

Rule argument

[crewrite-arg: okbytearray-02, F, [st, r, str] → [st, r, str]]
