Proof step 23 from proof fits-law-bxor-02 (previous step)

~32768 ≤ bcompl(s2i(sho2)), bcompl(s2i(sho2)) ≤ 32767 ⊦ bor(band(s2i(sho1), bcompl(s2i(sho2))), band(bcompl(s2i(sho1)), s2i(sho2))) = s2i(i2s(bor(band(s2i(sho1), bcompl(s2i(sho2))), band(bcompl(s2i(sho1)), s2i(sho2))))), s2i(i2s(band(bcompl(s2i(sho1)), s2i(sho2)))) = band(bcompl(s2i(sho1)), s2i(sho2)), s2i(i2s(bcompl(s2i(sho1)))) = bcompl(s2i(sho1))

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 24:
⊦ i ∈short → s2i(i2s(bcompl(i))) = bcompl(i)

Rule argument

name: bcompl-sis rotate: F subst: [i] → [s2i(sho1)]
