Proof step 1 from proof bits2int-zeros-01 (conclusion)

⊦ ¬ true ∈ bits → bits2int(bits + false ' + bits0) = bits2int(false + bits0)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ bits2int(bits + false ' + bits0) = bits2uint(bits0), true ∈ bits

Rule argument

Additional information

Used simplifier rules: bits2int-pos: ⊦ bits2int(false ' + bits) = bits2uint(bits);% ⊦ (bits + bits0) + bits1 = bits + bits0 + bits1;% ⊦ boolvar + bits = boolvar ' + bits;
