Benchmark
non-incremental/QF_NIA/20230328-sqrtmodinv-hoenicke/modInvVar1.smt2
This checks the validity of a line in computing the inverse of
denominator mod 2^256. The code is:
assume s > 1 && (denominator * inv1) mod s = 1
inv2 = inv1 * (2 - denominator * inv1)
assert (denominator * inv2) mod (s * s) = 1
See mulInvStepSimplified.smt2 for the reason why this benchmark is unsat.
