Proof step 8 from proof getar-putbar (previous step)

∀ r, r1, st. r = r1 ∨ getarray(r, putByteArray(bytes0, r1, st)) = getarray(r, st) ⊦ r = r1, getarray(r, putByteArray(by ' + bytes0, r1, st)) = getarray(r, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 4:
⊦ putByteArray(bytes, r, st) = putByteArray(bytes, r, 0, st)
Proof step 7:
∀ r, r1, st. r = r1 ∨ getarray(r, putByteArray(bytes0, r1, st)) = getarray(r, st) ⊦ r = r1, getarray(r, putByteArray(by ' + bytes0, r1, 0, st)) = getarray(r, st)

Rule argument

[crewrite-arg: putByteArray-all , F , [st, r, bytes] → [st, r1, by ' + bytes0] ]
