non-incremental/QF_BV/brummayerbiere2/smulov3bw0064.smt2

We verify a verification condition for a signed multiplication
overflow detection unit, which is described in
"Combined Unsigned and Two's Complement Saturating Multipliers"
by M. Schulte et al.

Let n be the bit-width, which is even.
If the n/2 + 1 most significant bits of the operands are zero, then
the overflow detection unit must not yield an overflow.

Bit-width: 64
