Proof step 6 from proof getbar-mod (previous step)

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

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ onlyModified(r, st, st0) → st[r0 -- _length] = st0[r0 -- _length]
Proof step 5:
onlyModified(r, st, st0), onlyModified(r, st, st0) ⊦ r = r0, getbytearray(r0, 0, st0[r0 -- _length] .intval, st) = getbytearray(r0, 0, st0[r0 -- _length] .intval, st0)
