Proof step 1 from proof fits-law-shr-01 (conclusion)

⊦ s2i(sho) i>> i = s2i(i2s(s2i(sho) i>> i))

User applied rule insert spec-lemma

And obtained the following new goals

Proof step 2:
⊦ abs(i i>> j) ≤ abs(i)
Proof step 3:
abs(s2i(sho) i>> i) ≤ abs(s2i(sho)) ⊦ s2i(sho) i>> i = s2i(i2s(s2i(sho) i>> i))

Rule argument

seq: ⊦ abs(i i>> j) ≤ abs(i) subst: [i, j] → [s2i(sho), i] rotate: F spec: intops inst: name: shiftrsign-abs-le

Additional information

Used terms: s2i(sho), i
