Proof step 11 from proof ushort-inj (previous step)

s2i(sho) = s2i(sho0) + 65536, s2i(sho0) < 0, ~65536 ≤ s2i(sho0), s2i(sho) ≤ 32767, ~32768 ≤ s2i(sho) ⊦ sho = sho0

User applied rule insert equation

And obtained the following new goals

Proof step 12:
s2i(sho0) < 0, ~65536 ≤ s2i(sho0), s2i(sho0) + 65536 ≤ 32767, ~32768 ≤ s2i(sho0) + 65536 ⊦ sho = sho0

Rule argument

pos: left 1 flags: discard
