Proof step 2 from proof longshiftzero-zero-03 (previous step)

0 ≤ i ⊦ i l>>> j = 0 ↔ i / 2 ^ band(j, 63) = 0

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ 0 ≤ i → i l>>> j = i >> band(j, 63)
Proof step 4:
0 ≤ i, 0 ≤ i ⊦ i >> band(j, 63) = 0 ↔ i / 2 ^ band(j, 63) = 0

Rule argument

name: longshiftzero-def-pos rotate: F subst: [j, i] → [j, i]

Additional information

Used terms: j, i
