Proof step 95 from proof ushort-band-shift (previous step)

255 + j0 = i * 256 + j1, 0 ≤ i, 0 ≤ j1, 256 * j0 + j < 0, j0 < 0, ~255 ≤ j0, ~256 ≤ j, j < 0, ~256 < j, ~65536 ≤ 256 * j0 + j, j1 < 256 ⊦ 255 + j0 = j1, j = 0

User applied rule cut formula

And obtained the following new goals

Proof step 96:
255 + j0 = i * 256 + j1, 0 ≤ i, 0 ≤ j1, 256 * j0 + j < 0, j0 < 0, ~255 ≤ j0, ~256 ≤ j, j < 0, ~256 < j, ~65536 ≤ 256 * j0 + j, j1 < 256 ⊦ i = 0, 255 + j0 = j1, j = 0

Rule argument

fma: i = 0

Additional information

Used simplifier rules: ⊦ i + 0 = i;% ⊦ i + j + i0 = (i + j) + i0;% ⊦ i + j = j + i; Used formulas: i = 0
