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

⊦ r = r0, getbytearray(r, 0, st[r -- _length] .intval, addarray(r0, ty, vals, st)) = getbytearray(r, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ getbytearray(r, st) = getbytearray(r, 0, st[r -- _length] .intval, st)
Proof step 5:
⊦ r = r0, getbytearray(r, 0, st[r -- _length] .intval, addarray(r0, ty, vals, st)) = getbytearray(r, 0, st[r -- _length] .intval, st)

Rule argument

[speclemmaarg: , getbytearray(r, st) = getbytearray(r, 0, st[r -- _length] .intval, st) ,[st, r] → [st, r] ,F ,storearrays , ,getByteArray-all ]
