Proof step 8 from proof fits-law-shr-01 (previous step)

abs(s2i(sho) i>> band(i, 31)) ≤ abs(s2i(sho)) ⊦ s2i(sho) i>> band(i, 31) = s2i(i2s(s2i(sho) i>> band(i, 31))), ¬ 0 < s2i(sho) i>> band(i, 31) ∧ ¬ 0 < s2i(sho)

User applied rule cut formula

And obtained the following new goals

Proof step 9:
0 < s2i(sho), abs(s2i(sho) i>> band(i, 31)) ≤ abs(s2i(sho)) ⊦ s2i(sho) i>> band(i, 31) = s2i(i2s(s2i(sho) i>> band(i, 31))), ¬ 0 < s2i(sho) i>> band(i, 31) ∧ ¬ 0 < s2i(sho)
Proof step 18:
abs(s2i(sho) i>> band(i, 31)) ≤ abs(s2i(sho)) ⊦ 0 < s2i(sho), s2i(sho) i>> band(i, 31) = s2i(i2s(s2i(sho) i>> band(i, 31))), ¬ 0 < s2i(sho) i>> band(i, 31) ∧ ¬ 0 < s2i(sho)

Rule argument

fma: 0 < s2i(sho)
