non-incremental/QF_BV/brummayerbiere3/maxxor032.smt2 

Propagating bounds through logical operators (unsigned context).
The maxXOR(a, b, c, d) algorithm computes the maximum of x ^ y, where
a <= x <= b  and  c <= y <= d.

From the book "Hacker's delight" by Henry S. Warren, Jr., page 62
We verify that the result is indeed the maximum.
