Proof step 28 from proof intshiftright-ls-01 (previous step)

bits2uint((false ' + bitsinvert(sublist(0, m, bits)))+1) = 0, mklist(true, i→n(j)) + int2bits(i) = true ' + bits, # int2bits(i) = m + 1, i < 0, 0 ≤ j, j < 32 ⊦ i = 0

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

seq: ⊦ true ∈ bits → bits2uint(bits) ≠ 0 subst: [bits] → [(false ' + bitsinvert(sublist(0, m, bits)))+1] rotate: F spec: int2bits inst: name: bits2uint-not-zero

Additional information

Used simplifier rules: ⊦ ¬ true ∈ bits → bits2uint(bits) = 0;% ⊦ ¬ true ∈ bits +1 ↔ false; Used terms: (false ' + bitsinvert(sublist(0, m, bits)))+1
