Proof step 7 from proof okbar-bytes2int-same (previous step)

0 ≤ st[r1 -- _length] .intval, bytes2int(getbytearray(r, st)) = bytes2int(getbytearray(r1, st)), st[r -- _length] .intval = st[r1 -- _length] .intval, okarray(r, byte_type, st), okarray(r1, byte_type, st), r ∈ st, r1 ∈ st ⊦ r = jvmref, r1 = jvmref, # getbytearray(r, st) = i→n(st[r1 -- _length] .intval)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 5:
⊦ 0 ≤ st[r -- _length] .intval → # getbytearray(r, st) = i→n(st[r -- _length] .intval)
Proof step 6:
⊦ okarray(r, ty, st) → ¬ st[r -- _length] .intval < 0
