Proof step 5 from proof intshiftright-unbounded-same (previous step)

i < 32, 0 ≤ i ⊦ bits2int(sublist(0, # int2bits(j), mklist(¬ 0 ≤ j, i→n(i)) + int2bits(j))) = j >> i

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 6:
⊦ i >> j = bits2int(sublist(0, # int2bits(i), mklist(int2bits(i).first, i→n(j)) + int2bits(i)))

Rule argument

name: shiftrsign-01 rotate: F subst: [j, i] → [i, j]

Additional information

Used simplifier rules: ⊦ int2bits(j).first ↔ j < 0;% ⊦ ¬ i < j ↔ j ≤ i; Used terms: i, j
