Proof step 4 from proof bytes2int-mone (previous step)

b2i(by) < 0 ⊦ bits2int(bytes2bits(i2b(~1) ' + by ' + bytes)) = bytes2int(by ' + bytes)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 5:
b2i(by) < 0 ⊦ bits2int(byte2bits(i2b(~1)) + byte2bits(by) + bytes2bits(bytes)) = bytes2int(by ' + bytes)

Rule argument

Additional information

Used simplifier rules: bytes2bits-rec: ⊦ bytes2bits(by ' + bytes) = byte2bits(by) + bytes2bits(bytes);% ⊦ (bytes + bytes0) + bytes1 = bytes + bytes0 + bytes1;
