Proof step 4 from proof okbytearray-this (previous step)

⊦ r = jvmref, okbytearray(r, addarray(r, byte_type, i, st)) ↔ ¬ i < 0

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ okbytearray(r, st) ↔ okarray(r, byte_type, st)
Proof step 3:
⊦ r = jvmref, okarray(r, byte_type, addarray(r, byte_type, i, st)) ↔ ¬ i < 0

Rule argument

[speclemmaarg: ,okbytearray(r, st) ↔ okarray(r, byte_type, st) ,[st, r] → [addarray(r, byte_type, i, st), r] ,F ,okfuns , ,okbytearray-01 ]
