Proof step 5 from proof okbytearray-02 (previous step)

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

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ validref(str, r, ty, st) ↔ r = jvmref ∨ st[r -- _type] .type ≤ ty ∧ ¬ junkref(str, r, st)
Proof step 4:
r = jvmref ∨ st[r -- _type] .type ≤ mkarraytype(byte_type) ∧ ¬ junkref(str, r, st) ⊦ r = jvmref, okbytearray(r, st)

Rule argument

[crewrite-arg: validref-def , F , [st, ty, r, str] → [st, mkarraytype(byte_type), r, str] ]
