Proof step 7 from proof intshiftrsign-abs-le (previous step)

abs(i) < abs(i i>> band(j, 31)) ⊦ ¬ i < 0 ∧ ¬ band(j, 31) ≤ 0

User applied rule cut formula

And obtained the following new goals

Proof step 8:
abs(i) < abs(i i>> band(j, 31)) ⊦ band(j, 31) = 0, ¬ i < 0 ∧ ¬ band(j, 31) ≤ 0

Rule argument

fma: band(j, 31) = 0

Additional information

Used simplifier rules: intshiftrsign-zero: ⊦ i i>> 0 = i;% ⊦ ¬ i < i; Used formulas: band(j, 31) = 0
