Proof step 2 from proof bytes2int-rec-bor (previous step)

⊦ bytes = [], bytes2int(bytes + by ') = bor(bytes2int(bytes) * 256, band(b2i(by), 255))

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ bytes ≠ [] → bytes2int(bytes + by ') = bytes2int(bytes) * 256 + band(b2i(by), 255)
Proof step 4:
bytes ≠ [] ⊦ bytes = [], bytes2int(bytes) * 256 + band(b2i(by), 255) = bor(bytes2int(bytes) * 256, band(b2i(by), 255))

Rule argument

name: bytes2int-rec rotate: F subst: [by, bytes] → [by, bytes]

Additional information

Used terms: by, bytes
