Proof step 7 from proof getbar-mod (previous step)

onlyModified(r, st, st0) ⊦ r = r0, getbytearray(r0, 0, st[r0 -- _length] .intval, st) = getbytearray(r0, st0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ getbytearray(r, st) = getbytearray(r, 0, st[r -- _length] .intval, st)
Proof step 6:
onlyModified(r, st, st0) ⊦ r = r0, getbytearray(r0, 0, st[r0 -- _length] .intval, st) = getbytearray(r0, 0, st0[r0 -- _length] .intval, st0)

Rule argument

[crewrite-arg: getByteArray-all, F, [st, r] → [st0, r0]]
