Proof step 20 from proof ushort-inj (previous step)

s2i(sho) + 65536 = s2i(sho0), s2i(sho0) ≤ 32767, 0 ≤ s2i(sho0), s2i(sho) < 0 ⊦ sho = sho0

User applied rule insert equation

And closed the goal!

pos: left 1 flags: rotate, discard

Additional information

Used simplifier rules: short-nle: ⊦ ¬ s2i(sho) ≤ ~32769;% ⊦ i + (* j) ≤ (* j0) ↔ i ≤ j0 - j;% ⊦ i + j + i0 = (i + j) + i0;% ⊦ i + j = j + i;
